OpenVMS Version 7.1 Release Notes

Starting with OpenVMS Alpha Version 7.0, the PXG graphics board is no longer supported.

C.2 DECthreads: POSIX 1003.4a Draft 4 Interface To Be Retired

V7.0

The POSIX 1003.4a, Draft 4 (or "d4") interface of DECthreads is slated for retirement in a future release. Applications that were written using the POSIX 1003.4a, Draft 4 interface should be migrated to the new POSIX 1003.1c standard (or "pthread") interface provided by DECthreads. A compatibility mode for the Draft 4 POSIX 1003.4a interface has been provided in this release to help ease migration. This compatibility mode will be removed in a future release.

C.3 DTK$ (DECtalk) Available as Freeware

V7.1

With OpenVMS Version 7.1, the DECtalk facility (DTK$) is moved from maintenance status to retired status. The source code for this library will be moved to freeware status and will be available with the release of Version 7.1 from the following sources for those interested in doing their own development and support:

On the freeware CD--ROM that ships with the OpenVMS operating system, starting with Version 7.1.

On the World Wide Web at the following URL:

http://www.openvms.digital.com/openvms/freeware/index.html

Starting with OpenVMS Version 7.1, Digital will no longer accept or act on CLDs posted against the DTK$ library.

C.4 Error Reporting Formatter (ERF) To Be Retired

V7.1

The Error Reporting Formatter (ERF) still ships with the current release of the operating system, but it will be retired in a future OpenVMS release. DECevent now replaces ERF as the bit-to-text translating tool for fault management on both VAX and Alpha systems.

C.5 ISA_CONFIG.DAT Unsupported in Future Release (Alpha Only)

V7.1

Support for using the SYS$MANAGER:ISA_CONFIG.DAT file to configure ISA devices will be discontinued in a future release of OpenVMS Alpha. If you use this file, you should convert to using the ISACFG utility from the console, and the new file-based autoconfiguration method for loading device drivers (as described in the OpenVMS Version 7.1 New Features Manual).

C.6 POLYCENTER Software Installation Utility: DECwindows Motif Interface To Be Retired

V7.1

The DECwindows Motif interface for the POLYCENTER Software Installation Utility will be retired in the next OpenVMS release. All functions of the POLYCENTER Software Installation utility will still be available from the DCL interface using the PRODUCT command. Starting with OpenVMS Version 7.1, the method of accessing the Motif interface has been changed to require using the new /INTERFACE=DECWINDOWS qualifier. For details, see Section 4.16.1.1.1.

C.7 PPL$ (Parallel Processing Library) Available as Freeware

V7.1

With OpenVMS Version 7.1, the Parallel Processing Library (PPL$) moves from maintenance mode to unsupported status. The source code for this library will be moved to freeware status and will be available with the release of Version 7.1 from the following sources for those interested in doing their own development and support:

On the freeware CD--ROM that ships with the OpenVMS operating system, starting with Version 7.1.

On the World Wide Web at the following URL:

http://www.openvms.digital.com/openvms/freeware/index.html

Starting with OpenVMS Version 7.1, Digital will no longer accept or act on CLDs posted against the PPL$ library.

If you have used PPL$, consider whether you can use the OpenVMS DECthreads library to implement concurrent applications. The DECthreads library has shipped with the OpenVMS VAX operating system since Version 5.5 and with the OpenVMS Alpha operating system since Version 1.0. Starting with OpenVMS Version 7.0, DECthreads has supported multiprocessing as part of its multithreading capabilities. In addition, DECthreads implements the industry-standard POSIX multithreading interface. For more information about DECthreads, see the Guide to DECthreads.

C.8 Selected $QIO Function Codes To Be Retired

V7.1

The $MOUNT and $DISMOU system services are the preferred method for mounting and dismounting shadow sets. In the past, Digital has also supported the use of $QIO function codes IO$_CRESHAD, IO$_ADDSHAD, and IO$_REMSHAD for these functions, although they were seldom, if ever, used. After this release, Digital will no longer support these function codes.

If any of your programs use these function codes, Digital recommends that you replace them with $MOUNT or $DISMOU system service calls, as appropriate.

C.9 Snapshot Facility Removed (VAX Only)

V7.1

With the release of OpenVMS VAX Version 7.1, the Snapshot facility has been removed. Snapshot was introduced with OpenVMS VAX Version 6.0 and was supported only on nonclustered VAX workstations. Enhancements to the OpenVMS operating system have made it impractical to continue maintaining this little used facility in OpenVMS VAX. (Snapshot was never available on Alpha systems.)

C.10 Archived Manuals

V7.1

Archived manuals are no longer maintained and are not part of the OpenVMS Documentation Set. However, they are available in PostScript and DECW$BOOK (Bookreader) formats on the OpenVMS Documentation CD--ROM. You can also order printed manuals through DECdirect (800--354--4825).

Table C-1 lists the manuals that have been archived starting with OpenVMS Version 7.1.
