Invokes the System Dump Analyzer utility, which analyzes a running system.
The /SYSTEM qualifier is required.
Requires CMKRNL (change-mode-to-kernel) privilege. Also requires PFNMAP
(map-by-PFN) privilege to access memory by physical address.
For more information about the System Dump Analyzer utility on Alpha and
Integrity server systems, see the VSI OpenVMS System Analysis Tools Manual
or online help.
Format:
ANALYZE/SYSTEM
1 /SYMBOL
Specifies an alternate system symbol table for SDA to use.
Format:
ANALYZE/SYSTEM/SYMBOL=system-symbol-table
system-symbol-table
The file specification of the SDA system symbol table required
by SDA to analyze a running system. The specified system-symbol-table
must contain those symbols required by SDA to find certain
locations in the executive image.
On Alpha and I64 systems, if you do not specify the /SYMBOL qualifier,
SDA uses SDA$READ_DIR:SYS$BASE_IMAGE.EXE to load system symbols
into the SDA symbol table.
On VAX systems, if you do not specify the /SYMBOL qualifier, SDA
uses SYS$SYSTEM:SYS.STB by default.
When you specify the /SYMBOL qualifier, SDA assumes the default disk
and directory to be SYS$DISK and [default-dir]; that is, the disk
and directory specified in your last SET DEFAULT command. If no
device and directory are given in the file name and the file is not
found in the current default directory, SDA attempts to open the file
SDA$READ_DIR:filename.type. If no type has been given in the file
name, SDA assumes .EXE. If you specify a file for this parameter that
is not a system symbol table, SDA halts with a fatal error.
2 – Examples
1. $ ANALYZE/SYSTEM
OpenVMS (TM) system analyzer
SDA>
This command invokes SDA to analyze the running system.
2. On Alpha and I64 systems:
$ ANALYZE/SYSTEM/SYMBOL=SDA$READ_DIR:SYS$BASE_IMAGE.EXE SYS$SYSTEM
This command invokes SDA to analyze the running system, using
the base image in SDA$READ_DIR.
3. On VAX systems:
$ ANALYZE/SYSTEM/SYMBOL=SYS$CRASH:SYS.STB SYS$SYSTEM
This command invokes SDA to analyze the running system, using
the system symbol table at SYS$CRASH:SYS.STB.
