- Provide examples of adding proxies using the DOMAIN,
LOCAL, and DECdns fullnames in the NETWORK_MANAGEMENT
ACCESS_CONTROL section.
- Modify "set dtss servers required" example because the
"s" was missing, and the command doesn't parse without
it.

2.19 SYS$LIBRARY:NCLSHR.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:31:42.00

ECO04:

- Corrected backtranslation of IP address so address
displays now display the fully qualified host name
following the IP address. (See also NET$SESSION_
CONTROL.EXE.) If a BIND server is not available and
you still want to see the fully qualified name, do the
following:

1. Modify the local IP host database:

$ tcpip set nohost trundy
$ tcpip set host trundy.xpr.eds.vendors.cpqcorp.net -
/addr=161.114.95.148/alias=trundy

2. Flush the old cache entry so the next lookup will get
the fully qualified name.
- Correct the order of the IP address display now that
the ISO format is used to store the address within the
towerset.

ECO01:

- Suppress "getlist" error on NCL SHOW displays

2.20 SYS$SYSTEM:NET$ACP.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:48:48.00

- Include for compatibility with CDI$SHR.

2.21 SYS$LOADABLE_IMAGES:NET$ALIAS.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:34:46.00

ECO04:

- Include support for shut [node node-id] alias port
port-name. See NCL help for more information.
- Make exclusive mode lock conversion synchronous in
Alias$SendVB to prevent hang while shutting alias.
- Make exclusive mode lock conversion synchronous in
Alias$Update_App to prevent possible hang while enabling
(or re-enabling) alias port.
- Lowered IPL in several system service completion
routines. DECnet services were improperly called with
elevated IPLs.

- Test for null port pointer during DISABLE ALIAS PORT
command processing to prevent disabled alias port from
being used.
- Prevent hangs on calls to $ENQ system service because
a thread of execution was running at an elevated IPL.

ECO02:

- Prevent Round Robin queue corruption.

2.22 SYS$MANAGER:NET$APPLICATION_SHUTDOWN.TEMPLATE:

File Identification: 19-AUG-2002 13:17:17.00

ECO04:

- New template. Example of shutting down applications
prior to network shutdown. Placing application shutdown
commands in SYSHUTDWN.COM causes NET$SHUTDOWN to hang
because NET$SHUTDOWN is called before the application
shutdown commands are encountered.

2.23 SYS$SYSTEM:NET$AUTOGEN.COM:

File identification: 7-MAY-2002 16:19:36.00

ECO04:

- Changed $MC AUTHORIZE command to use command symbol
(AUTHORIZE :== $AUTHORIZE")

2.24 SYS$SYSTEM:NET$CCR.EXE:

Image Identification: "V7.3ECO04" 6-APR-2004 00:00:18.00

- Include for compatibility with NET$MOP.

2.25 SYS$MANAGER:NET$CONFIGURE.COM:

File Identification: 5-APR-2004 18:00:20.00

ECO04:

- Changed copyright information.
- When using Option 2 the towers weren't being updated
correctly. NET$CONFIGURE was deleting them because nsp_
wanted and osi_wanted symbols weren't set.

ECO02:

- Corrected error that caused the Phase IV prefix to be
ignored when changing the AFI to any value other than
49.
- Correct towers when running with an AFI other than 49
and a Phase IV compatible address, the preDSP portion of
the Phase IV prefix was dropped from the towers.
- When an extended address was used the Phase IV address
is 0.0 so the towers incorrectly updated using the AA-
00-04-00-xx-xx form of the node ID.

ECO01:

- Change NET$CONFIGURE option 1.
- Remove obsolete decnet_loc_register calls.
- Display a warning that the system must be rebooted if
the DECnet address has been changed.
- Make sure that all temporary files from an aborted
session will be deleted.

2.26 SYS$UPDATE:NET$CONFIGURE_UPGRADE.COM:

File Identification: 5-APR-2004 18:00:55.00

- Include for compatibility with NET$CONFIGURE.COM

2.27 SYS$LOADABLE_IMAGES:NET$DRIVER.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:49:37.00

ECO04:

- Improved the reporting of connection timeouts in the
transmit and receive queue processing code. The code
now returns the traditional, more specific timeout error
status SS$_LINKEXIT instead of the generic error status
SS$_FILNOTACC.
- Corrected a problem causing a process using the NET
device to hang in the RWAST state. This problem was seen
when multiple deassign calls were made for a connection
instance. (For example, a remote system requesting a
disconnect at the same time as the local system.)
- Corrected a problem seen when a user program received
notification of I/O completion using LOCAL event flags.
Occasionally, the event flag was set before the IOSB and
the data buffer were properly set.

- Remove gratuitous IOLOCK8 acquisition and release on
I/O completion.

ECO01:

- Acquire and release IOLOCK8 in a macro for the DAB
queue.

2.28 SYS$MANAGER:NET$LOGICALS.TEMPLATE:

File Identification: 10-SEP-2002 10:28:53.00

ECO04:

- Increased default BYTLM for MOP.
- New logical, NET$LOCAL_CLOSE, has been introduced
and if set to 1 forces a close of NET$LOCAL_NAME_
DATABASE.DAT after each reference. If logical is not
defined, then the database is left open. The use of
the logical might effect performance but it prevents
problems associated with constantly open files (possible
merge problems if database is moved).
- Example of shutting down applications prior to network
shutdown.

2.29 SYS$SYSTEM:NET$MOP.EXE:

Image Identification: "V7.3ECO04" 6-APR-2004 00:00:04.00

ECO04:

- Corrected a routine to explicitly set IPL to 0 before
issuing thread signal calls that require an IPL of 0.
Also, corrected which thread signal calls were used.
This problem caused the MOP process to hang when it was
trying to load multiple servers simultaneously.
- Correct the buffer length derived from the terminal
server's SYSID message for MOP Console Carrier Protocol
used by TSM.

ECO01:

- Add debugging code for DECthreads.

2.30 SYS$LOADABLE_IMAGES:NET$MOPS0.EXE:

Image Identification: "V7.3ECO04" 6-APR-2004 00:00:09.00

- Include for compatibility with NET$MOP.

2.31 SYS$LIBRARY:NET$NISCS_LAA.EXE:

Image Identification: "MOPLAA V3.0" 5-APR-2004 23:42:22.00

ECO01:

- Prevent KRNLSKNV crash during load with host based
shadowed disk.

2.32 SYS$LOADABLE_IMAGES:NET$OSDRIVER.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:50:09.00

ECO04:

- Improved the reporting of connection timeouts in the
transmit and receive queue processing code. The code
now returns the traditional, more specific timeout error
status SS$_LINKEXIT instead of the generic error status
SS$_FILNOTACC.
- Corrected a problem causing a process using the OS
device to hang in the RWAST state. This problem was seen
when multiple deassign calls were made for a connection
instance. (For example, a remote system requesting a
disconnect at the same time as the local system.)
- Corrected a problem seen when a user program received
notification of I/O completion using LOCAL event flags.
Occasionally, the event flag was set before the IOSB and
the data buffer were properly set.

2.33 SYS$LOADABLE_IMAGES:NET$OSVCM.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:47:01.00

ECO04:

- Corrected a possible double deallocation problem that
occurred on incoming sessions where the remote session
partner and the device driver simultaneously attempted
to close the session.

ECO02:

- Remove only data transmit fork for performance on I/O
completion by just calling session directly.

2.34 SYS$LIBRARY:NET$PROCESS_EMAA.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:27:04.00

ECO04:

- Corrected a system crash caused by a problem with MCRP
buffer allocation and initialization in the NET$EMAA_
Response routine. The buffer consists of a fixed length
control block which includes a pointer to a variable
length output string that is appended to the control
block. The code was not properly initializing the output
string pointer to null when the output string length was
zero.
- Corrected a system crash seen while managing a MOP
entity. A block deallocation routine was running at
an elevated IPL (IOLOCK8) when a page fault occurred.
The elevated IPL is not required and was removed, thus
allowing the page faulting to occur at a lowered IPL
(IPL 11).

ECO02:

- Raise default CML BYTLM to allow NCL SHOW SESSION
CONTROL to handle more than 1500 connections. See
Section 5 for more information.

2.35 SYS$LOADABLE_IMAGES:NET$ROUTING_ES.EXE:

Image Identification: "V7.3ECO04" 6-APR-2004 00:01:37.00

ECO04:

- Ensure that an FDDI circuit is enabled before sending
the last chance ES_HELLO (for all bcst circuits).
- Corrected a system crash seen when disabling alias
ports. The code was not handling the case where there
were no ports to disable.
- Corrected a system crash caused by improper integrity
checking of incoming ES Hello messages. Also, if the
integrity checking failed, a bugcheck was forced. This
integrity check was corrected and the routine returns
appropriate status instead of bugchecking.

- Remove gratuitous IOLOCK8 acquisition and release.

ECO02:

- Remove check for invalid NSAP on initial ES hello
message by not checking the area address of the NSAP.

2.36 SYS$LOADABLE_IMAGES:NET$ROUTING_IS.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:38:17.00

ECO04:

- Deleted unnecessary Phase IV parameter checks when in
an OSI-only host-based routing environment.
- Modified the output of the SHOW ROUTING ALL command
to omit all Phase IV parameters in a pure OSI host-based
routing environment.
- Change the default values for the routing
characteristics manual L1 algorithm and manual L2
algorithm to link state. Using link state as the
default prevents several dependencies on Phase IV
information not provided in a pure OSI host-based
routing environment.

ECO02:

- Raise the originating queue limit for broadcast
circuits to correct performance problem.

ECO01:

- Modify alias forwarding to prevent the "transmit queue
length" from becoming negative, and subsequent packets
from being discarded.

2.37 SYS$LOADABLE_IMAGES:NET$ROUTING_VCM.EXE:

Image Identification: "V7.3ECO04" 6-APR-2004 00:01:27.00

ECO02:

- Check the VCIB pointer first before deallocating the
VCRP to prevent a possible system crash on shutdown
because the port may have been in the process of being
deallocated.

2.38 SYS$LIBRARY:NET$SDA.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:46:23.00

ECO01:

- Add updates for TPCONS, X25 Relay, and XOT.

2.39 SYS$SYSTEM:NET$SERVER.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:52:36.00

ECO01:

- Prevent possible %IPC-F-DCLSRVFAIL when the
NETSERVER$TIMEOUT is set to zero.

2.40 SYS$LOADABLE_IMAGES:NET$SESSION_CONTROL.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:50:54.00

ECO04:

- Corrected a problem seen when a user program received
notification of I/O completion using LOCAL event flags.
Occasionally, the event flag was set before the IOSB and
the data buffer were properly set.
- Modified how Session Control responds when a node's
cache entry is stale (that is, the node name is found
but the address is not reachable). Formerly, the node
would remain unreachable until the cache was updated.
Now, the cache is bypassed, the proper address found,
and the cache is updated.
- Correct some buffer sanity checking logic in the $IPC
interface.
- Corrected an IPL level problem that in turn caused
session control to honor unreasonably large memory
allocation requests from the $IPC interface.
- Fix incoming alias table. All named objects were
incorrectly assumed to be the TASK object.
- Prevent possible double deallocation of a disconnect
VCRP by dereferencing a pointer in the session
port block immediately after the disconnect VCRP is
completed.
- Remove gratuitous IOLOCK8 acquisition and release.

- Correct IP address backtranslation to display the
fully qualified host name in the following commands (see
also NCLSHR.EXE);

MCR NCL SHOW ADDR ...
MCR NCL SHOW OSI TRANSPORT PORT * REMOTE RFC1006 IP ADDR ...
MCR NCL SHOW OSI TRANSPORT LOCAL NSAP IP_ANY REMOTE NSAP * IP ADDR ...

ECO02:

- Correct DECnet Over IP state table transition crash
that could happen when an expedited data message was
received after a disconnect from the remote system.
- Corrected connections to DECnet servers when NET_
CALLOUTS was set to 255 in SYSGEN.
- Remove spurious "Delete Maintained Object" message on
system startup.
- Prevent premature deallocation of session disconnect
VCRPs.

ECO01:

- Correct "Incoming Connect Orphan Queue" VCRP
disconnect deallocation.
- Modify EXE$IPC to always return the caller to IPL 0 so
that callers will never unknowingly inherit the ASTDEL
IPL.

2.41 SYS$STARTUP:NET$SHUTDOWN.COM:

File identification: 5-APR-2004 18:00:46.00

ECO04:

- Changed copyright information.

ECO01:

- Prevent possible shutdown hang in Transports or
Routing.

2.42 SYS$STARTUP:NET$STARTUP.COM:

File identification: 5-APR-2004 18:00:38.00

ECO04:

- Corrected a condition that caused NET$STARTUP
to output several internal error messages to the
SYS$SPECIFIC:[SYSEXE]STARTUP.LOG file when the STARTUP_
P2 system parameter was set to "PD". Also, changed
copyright information.
- Increased default BYTLM for MOP.
- Added support for startup_p2 SYSGEN parameter.
Controls output of STARTUP.COM (and now
NET$STARTUP.COM).

ECO01:

- Prevent PGFIPLHI when Autogen does not complete and
LIBOTS code is not properly mapped into memory. If
LIBOTS is not resident then have the network startup
fail with NET$STARTUP_STATUS set to OFF-AUTOGENREQ.

2.43 SYS$LOADABLE_IMAGES:NET$TPCONS.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:50:50.00

ECO04:

- Modified the code to correctly set up local IP address
and TCP port fields. See also NET$TRANSPORT_OSI for more
information about how this change allowed the correct
local RFC1006 and remote RFC1006 IP address and port
number characteristics to be displayed.
- Modified the code to correctly handle a control block
inconsistency seen during processing of an incoming
disconnect when the local system is also initiating a
disconnect (rather than force a system crash).
- Corrected a self-imposed system crash seen during
OSI transport disabling where, under certain timing
conditions, a local control block being processed for
deallocation was found to be still active. The block is
now deactivated prior to deallocation.
- Corrected a stale pointer problem when taking down a
connection. Added a test of the pointer before using it
to complete the take down.

- Corrected a timing problem between TPCONS and
TRANSPORT_OSI. Logic was improved to prevent timing-
related problems between the two modules as they
deallocate internal data structures.
- Removed sanity checking in DeallocateTPCB that was
no longer compatible with newer HP TCP/IP Services for
OpenVMS releases.
- Clean up Connect Initiate error handling so that the
code does not try to reference fields in a Connect Init
structure that could not be allocated.
- Remove a forced bugcheck on a change of address when
the VCIB structure was removed in system shutdown.
- Remove a forced bugcheck that occurred during
connection takedown if a deferred transmit was pending.
- Reverse the IP address in the towerset from DNA
format to use the ISO format (i.e., transmitted most
significant byte first).

ECO02:

- Modify TPCONS design to enable the TCP/IP PWIP driver
to be restarted without a DECnet restart.
- Multiple changes to prevent exotic timing problems
with the latency in TCP/IP Services I/O completion.

ECO01:

- Correct a design problem to allow for very long
latency in TCP/IP Services between the transmit request
and the actual completion, if there are any problems in
TCP/IP delivering the data message.

2.44 SYS$LOADABLE_IMAGES:NET$TRANSPORT_NSP.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:46:51.00

ECO04:

- Corrected a problem resulting in poor throughput
when NSP was using piggyback ACKs. The code now sends
a standalone ACK if no data segment is queued for
transmission.
- Corrected a problem that caused circuit failover
on a dual LAN connection system to fail when the NSP
transport was in use.

- Reformat transmit VCRPs to prevent buffer possible
buffer overflow which might in a very unusual case
result in non-paged pool corruption. Also, modified
how the variable-length area (headers and user data)
of the VCRP are formatted to prevent the possibility of
referencing a location outside the allocation block.
- Remove gratuitous IOLOCK8 acquisition and release.
- Enlarge NSP OOOP cache from 7 to 32.

ECO02:

- Corrected the transmit copy code to handle the
occurrence of an internal zero pointer value which could
occur with some I/O cancellations.
- Correct null pointer crash in ACT$RCV_CI.

ECO01:

- Allow a connection to be disconnected immediately
for a dysfunctional link rather than waiting for the
timeouts to complete.

2.45 SYS$LOADABLE_IMAGES:NET$TRANSPORT_OSI.EXE:

Image Identification: "V7.3ECO04" 5-APR-2004 23:47:06.00

ECO04:

- Corrected a session hang problem seen when a
disconnect was received from the remote system and
was being processed at the same time that a request
to deaccess the NET channel came from the local system.
- Corrected a double deallocation of the NCCB seen
during the disabling of the OSI transport when DECnet
is shutting down.
- Modified the code to correctly display the local
RFC1006 and remote RFC1006 IP address and port number
characteristics instead of "<Default value>" and "0"
respectively.
- Corrected a problem seen during connection takedown
where the Remote Service Provider (RSP) list was in the
process of being modified as it was referenced during
the take down. Checking has been added to ensure the
returned RSP structure is valid.

- Corrected a timing problem between TPCONS and
TRANSPORT_OSI. Logic was improved to prevent timing-
related problems between the two modules as they
deallocate internal data structures.
- Ensure that the TPCB structure is properly deallocated
in the port deletion code responsible for the final
rundown of DECnet over TCP/IP connections.
- Ensure that all routines calling a NCCB queue
manipulation routine have IOLOCK8.
- Corrected the code to properly handle a rare situation
that can occur if a request to transmit is made to
routing and the permission is not granted until
transport has begun to terminate a connection. A null
buffer pointer was not being handled properly. Added
the same null pointer check to several other transport
routines.
- Reformat transmit VCRPs to prevent buffer possible
buffer overflow which might in a very unusual case
result in non-paged pool corruption.
- Remove gratuitous IOLOCK8 acquisition and release.

ECO02:

- Corrected queue synchronization problem that could
causes system crashes during connection establishment
and termination on multiprocessor systems.
- Corrected the code to properly handle a rare situation
that can occur if a request to retransmit is made
to routing and the permission is not granted until
transport has begun to terminate a connection. A null
buffer pointer was not being handled properly.
- Removed some logic that had been included to handle an
obsolete protocol quirk in older PC platforms. The code
was found to be responsible for long delays under rare
circumstances.
- Modify the deallocation of chained receive DCBs from
PWIPdriver to prevent possible system crash in OSI
Transport or TPCONS.
- Modify check for a valid NCCB which had been optimized
out of the code by the ALPHA BLISS compiler.
- Prevent crash in remote service provider counter
routine with more integrity checking.
- Modify OSITP design to enable the TCP/IP PWIPdriver to
be restarted without a DECnet restart.

- Multiple changes to prevent exotic timing problems
with the latency in TCP/IP Services I/O completion.

ECO01:

- Change the action routine on a TPDU error in a WFNC
(wait for network confirm) state to ACT$P_TPDUERR rather
than bugcheck.

Image Identification: "V7.3ECO04" 5-APR-2004 23:48:02.00

ECO04:

- Corrected a system crash seen when CTF tracing was
active during a shutdown of the OSI transport. During
transport shutdown, the common code for handling trace
terminations failed to verify the existence of the trace
information buffer before using a pointer within the
buffer.
- Update ECO number in the DECNET_VERSION item code to
"00050E07". Note: "00050E03" was not used, "00050E04"
was used for V7.3-1, "00050E05" was used for V7.3-1
ECO01, "00050E06" was used for V7.3 ECO03 for Alpha
only, "00050500" was inadvertently used for V7.3-1
ECO02. Future 7.3 ECOs, if any, will use "00050Exx"
(where xx is 08 or greater); future 7.3-1 ECOs, if any,
will use "00050Fxx" (where xx is 03 or greater).

ECO02:

- Update ECO number in the DECNET_VERSION item code to
"00050E02".

ECO01:

- Update ECO number in the DECNET_VERSION item code to
"00050E01".

3.2 Problems Corrected in DECdns Images

ECO04:

- Corrected a problem that caused a subsequent device to
remain uninitialized if a lower device of the same type
was offline or unavailable.
- Corrected a problem that could cause more than three
copies of the DNS$CHFAIL.LOG to be present on the
system. This condition occurred when the file version of
DNS$CHFAIL.LOG cycled through the upper version boundary
(that is, cycling from version 32767 back to version
1). The code now correctly handles this situation
and maintains three copies of the file. File versions
are rolled over when the file version reaches 32000.
For example, if versions 31998, 31999, and 32000 are
present, the code renumbers the files to version 1, 2,
and 3, respectively.
- Corrected a problem that could cause multiple copies
of the file used to maintain the current cache file
version (SYS$SYSTEM:DNS$CACHE.VERSION) to be present
on the system. This condition occurred when the file
version of DNS$CACHE.VERSION cycled through the upper
version boundary (that is, cycling from version 32767
back to version 1). The code now correctly handles this
situation and maintains a single version of the file.
- Corrected a system crash situation during DNS rundown
caused by using a stale (that is, null) pointer. The
code now checks the pointer before using it.
- Fix memory leak in DNS$ADVER when CSMA-CD station
disabled using NCL.
- Fix maybe bit processing and failover. Speedup
failover when no response from the application.
Also corrects problems observed during clearinghouse
processing.

- Include changes to DNS$CONFIGURE for compatibility
with NET$CONFIGURE changes.
- Internal code changes due to V7.3-1 compiler changes

ECO02:

- Correct access violation in dns$configure on invalid
full name.
- Correct default namespace missing problem.
- Correct failure to flush cache on disable.
- Add code to give detailed dump of cache DNS$CADUMP.
- Add trace support for DEB$K_FULLNAME_UID, DEB$K_
PROGRESS.
- Cleanup handling of context information.

ECO01:

- Include cache rollover correction, poolcheck and read
permanent decnet database to get local towerset.
- Add support for new trace code.
- Add support for EB and EI device types.
- Brann Cache Calculation modified to accommodate cache
sizes in a large memory environment.
- Prevents NSAP's with a prefix of %x49 from being
inserted in the cache if the configured prefix is other
than %x49.
- Also, there is a correction to preserve the STICKY bit
in the cache, if it was previously set, when the address
of an item in the cache is updated.
- Prevents the DNS$ADVER process from crashing when a
"SHOW DNS CLERK REMOTE CLEARINGHOUSE ..." command is
issued. This problem sometimes appears as hang to the
user when a command similar to the one shown above is
issued.
- Corrected the clerk treewalk algorithm to prevent the
algorithm from failing to find the desired clearinghouse
to satisfy the name lookup request. Typically, the
symptom of this problem was the return status of DNS$_
NOCOMMUNICATIONS on a "SHOW CLEARINGHOUSE ..." command
when the clerk should have been able to connect the
proper clearinghouse.

3.3 New Logicals for DNS$ADVER Image

Added the ability to define the following logical names in
the system logical name table:

DNS$ADVER_AST_LIMIT
DNS$ADVER_BUFFER_LIMIT
DNS$ADVER_EXTENT
DNS$ADVER_MAX_WORKING_SET
DNS$ADVER_PAGE_FILE

These logical names correspond to qualifiers on the RUN
statement which are described in the OpenVMS documentation.
If any of these logical names are defined at the time the
DNS$ADVER process starts up, then the values defined for
these logical names are used instead of the default quotas.

Typically, these logical names are defined in the
SYS$MANAGER:SYLOGICALS.COM file. This is necessary because
the logical names need to be defined before the DNS$ADVER
process starts up.

One reason to use these logical names is if you have
a system is configured with more than two ethernet
controllers. Another reason is to define increased quota
for the DNS$ADVER process when you receive a message
on the console during startup that the DNS cache is not
initialized (DNS$_NOCACHE,"Clerk cache not initialized").

Selected default quotas for the DNS$ADVER process have
also been increased for the ECO 72. The selected quotas
that have been increased include direct I/0, enqueue limit,
queue limit, buffer limit and maximum_working_set.

4 Restriction When Using Applications Supported Using Cluster
Aliases

Due to a design restriction, incoming ALIAS connections are
forwarded to cluster members somewhat differently depending
upon whether the SESSION CONTROL APPLICATION entity's
ADDRESS set contains a NUMBER parameter (equivalent
to Phase IV's connect by object number) or a TASK
parameter (equivalent to Phase IV's connect by object
name). For an incoming connect by object number, each
ALIAS entity has access to a cluster-wide object number
table that specifies which object numbers have been
defined for each cluster member and the status of their

INCOMING ALIAS characteristic. The result is that the
connection forwarding mechanism works as expected, that
is, connections are forwarded or not forwarded to cluster
members correctly depending upon whether the application
exists on the member and depending on the setting of the
INCOMING ALIAS parameter.

However, the mechanism for mapping incoming connections
by object name using this cluster-wide object number
table does not exist and the result is that connections
are forwarded to a given cluster member regardless of
whether the application exists on a given member and
regardless of the setting of the INCOMING ALIAS parameter
on a given member. If you wish to restrict access to a
network application supported using a cluster alias (either
by not having the application present on a member or by
setting the INCOMING ALIAS characteristic to FALSE on a
member), you must create the SESSION CONTROL APPLICATION by
supplying the NUMBER keyword for the ADDRESS characteristic
(that is, supplying the object number), so that connection
forwarding works as expected.

5 Tuning OpenVMS to Support the Larger CML BYTLM Value

The default BYTLM value for CML has been increased from
10000 to 64000. This correction was done to prevent NCL
from returning the NCL-E-OVERFLOWBYTLM error message when
large amounts of data were needed from CML. If you have
ever experienced this problem, or if your MAXBUF value
is already set to 64000 and you have received NCL-E-
NORESOURCEAVAIL error messages, then you should make the
changes described in this section.

To fully take advantage of the increased BYTLM value, do
the following:

1. Increase the value of MAXBUF to 64000 if you have not
done so already.

2. Increase the value of PQL_MBYTLM to 84000.

3. Raise the BYTLM quota on any account that might issue
commands requiring the increased resources to 65000.
Be sure to do this to at least SYSTEM, CML$SERVER,
and MICRO$SERVER accounts. For example, to modify the
CML$SERVER account, use the following command:

$ RUN SYS$SYSTEM:AUTHORIZE
UAF> MODIFY CML$SERVER/BYTLM=65000

4. Check for the existence of the logicals NET$ACP_
BYTLM, NET$EVD_BYTLM, AND NET$MOP_BYTLM. If any
of these logicals are defined and they are set to
a value lower than 65000, modify their entries in
SYS$MANAGER:NET$LOGICALS.COM to raise their value to
6500.

Note: SYS$MANAGER:NET$STARTUP.COM may fail with -NCL-E-
NORESOURCEAVAIL, no resources available. This is because
the changes in NET$PROCESS_EMAA require more Buffered I/O
in process context. If the system startup should fail then
the sysgen parameter PQL_MBYTLM must be increased to give
this process more BYTLM Quota.
