System Dump Analyzer
/SYMBOL
/SYMBOL
Specifies a system symbol table for SDA to use in place of the system symbol
table it uses by default (SYS$SYSTEM:SYS.STB).
Format
/SYMBOL =system-symbol-table
Parameter
system-symbol table
File specification of the SDA system symbol table needed to define symbols
required by SDA to analyze a dump from a particular system. The specified
system-symbol-table must contain those symbols required by SDA to find
certain locations in the executive image.
If you do not specify the /SYMBOL qualifier, SDA uses SYS$SYSTEM:SYS.STB
by default. When you do specify the /SYMBOL qualifier, SDA assumes the default
disk and directory to be SYS$DISK: that is, the disk and directory specified in
your last SET DEFAULT command. If SDA is given a file that is not a system
symbol table in the /SYMBOL qualifier, it halts with a fatal error.
Description
The /SYMBOL qualifier allows you to specify a system symbol table, other than
SYS$SYSTEM:SYS.STB, to load into the SDA symbol table. This might be
necessary, for instance, to analyze a crash dump taken on a processor running a
different version of OpenVMS.
You can use the /SYMBOL qualifier whether you are analyzing a system dump or
a running system.
Example
$ ANALYZE/CRASH_DUMP/SYMBOL=SYS$CRASH:SYS.STB SYS$SYSTEM
This command invokes SDA to analyze the crash dump stored in
SYS$SYSTEM:SYSDUMP.DMP, using the system symbol table at
SYS$CRASH:SYS.STB.
