Extracts the error log buffers from the dump file and places them into the binary file called CLUE$ERRLOG.SYS.
CLUE ERRLOG
None.
None.
CLUE ERRLOG extracts the error log buffers from the dump file and places them into the binary file called CLUE$ERRLOG.SYS.These buffers contain messages not yet written to the error log file at the time of the failure. When you analyze a failure on the same system on which it occurred, you can run the Error Log utility on the actual error log file to see these error log messages. When analyzing a failure from another system, use the CLUE ERRLOG command to create a file containing the failing system's error log messages just prior to the failure. System failures are often triggered by hardware problems, so determining what, if any, hardware errors occurred prior to the failure can help you troubleshoot a failure.
You can define the logical CLUE$ERRLOG to any file specification if you want error log information written to a file other than CLUE$ERRLOG.SYS.

131 11-MAY-1994 00:44:38.97 * Crash Entry
The CLUE ERRLOG command diplays the sequence, date, and time of each error log buffer extracted from a dump file in the file CLUE$ERRLOG.SYS.
Updates history file and generates crash dump summary output.
CLUE HISTORY [/qualifier]
None.
/OVERRIDE
Allows execution of this command even if the dump file has already been analyzed (DMP$V_OLDDUMP bit set).
This command updates the history file pointed to by the logical name CLUE$HISTORY with a one-line entry and the major crash dump summary information. If CLUE$HISTORY is not defined, a file CLUE$HISTORY.DAT in your default directory will be created.In addition, a listing file with summary information about the system failure is created in the directory pointed to by CLUE$COLLECT. The file name is of the form CLUE$node_ddmmyy_hhmm.LIS where the timestamp (hhmm) corresponds to the system failure time and not the time when the file was created.
The listing file contains summary information collected from the following SDA commands:
- CLUE CRASH
- CLUE CONFIG
- CLUE MEMORY/FILES
- CLUE MEMORY/STATISTIC
- CLUE PROCESS/RECALL
- CLUE XQP/ACTIVE
Refer to the reference section for each of these commands to see examples of the displayed information.
The logical name CLUE$FLAG controls how much information is written to the listing file.
- Bit 0---Include crash dump summary
- Bit 1---Include system configuration
- Bit 2---Include stack decoding information
- Bit 3---Include page and swap file usage
- Bit 4---Include memory management statistics
- Bit 5---Include process DCL recall buffer
- Bit 6---Include active XQP process information
- Bit 7---Include XQP cache header
If this logical name is undefined, all bits are set by default internally and all information is written to the listing file. If the value is zero, no listing file is generated. The value has to be supplied in hexadecimal form (for example, DEFINE CLUE$FLAG 81 will include the crash dump summary and the XQP cache header information).
If the logical name CLUE$SITE_PROC points to a valid and existing file, it will be executed as part of the CLUE HISTORY command (for example, automatic saving of the dump file during system startup). If used, this file should contain only valid SDA commands.
Refer to Section 2.3 for more information on site-specific command files.
This command is obsolete.
CLUE MCHK
None.
None.
The CLUE MCHK command has been withdrawn. Issuing the command produces the following output, explaining the correct way to obtain MACHINECHECK information from a crash dump.Please use the following commands in order to extract the errorlog buffers from the dumpfile header and analyze the machine check entry:
$ analyze/crash sys$system:sysdump.dmp SDA> clue errlog SDA> exit $ diagnose clue$errlog

Displays systemwide performance data such as page fault, I/O, pool, lock manager, MSCP, and file system cache.
The CLUE MEMORY command displays memory- and pool-related information.

#6The CLUE MEMORY/LOOKASIDE command summarizes the state of nonpageable lookaside lists. For each list, an indication of whether the queue is well formed is given. If a queue is not well formed or is invalid, messages indicating what is wrong with the queue are displayed. This command is analogous to the SDA command VALIDATE QUEUE.
These messages can also appear frequently when the VALIDATE QUEUE command is used within an SDA session that is analyzing a running system. In a running system, the composition of a queue can change while the command is tracing its links, thus producing an error message.
