XMSTUFF is a program to do explore/report some information about
the Transaction Manager (XM) on the current system.
Although some care is taken to check parameters, this is still an
experimental program. To date, no problems have been seen, but
be careful.
The user may want to issue a process-local breakpoint at xm_sf
...if hit, do: mr pc [sr4.r2]; abort
-----------------------------------------------------------
Commands:
Exit (or: //)
Terminates the program.
GETVSets [options]
options ::= < noFAST | noSLOW >
Help [keyword] (or: ?)
HELP keyword displays any help text associated with the
specified keyword.
HELP <return> displays the entire help file.
LISTvs [options]*
options ::= < noALLVOLUMES | noLOGFiles | noMembers |
noVerbose | noXm >
Lists all known/mounted volume sets. For each set, some
information is listed (depending upon the other options).
ALLVOLUMES lists all the mounted volumes, regardless of
volume set.
LOGFILES lists statistics from the XM checkpoint logffiles
for all volume sets.
MEMBERS lists all the member volumes of each volume set.
VERBOSE is equivalent means ALLVOLUMES, XM.
LOGS [noVerbose]
Causes XMSTUFF to do a call xm_checkpoint_ssm_maps and
xm_do_checkpointlog for every mounted volume set (other than
$SYS (MPEXL_SYSTEM_VOLUME_SET)).
For $SYS, calls checkpointsystemlog;
Example output:
Doing checkpointlog on MPEXL_SYSTEM_VOLUME_SET
lsrowptr = $81c172e0, volid = $056c0001010e3558
(checkpointsystemlog)
Doing checkpointlog on BIG
lsrowptr = $81c17430, volid = $056c0001384f1fb3
LSID [volumeid# | ALL | BOTH | DUMP]*
LSID lists information about a specific volume set (specified
via volume ID) or about all volume sets.
NOTE: do not provide it with invalid volume IDs, or with
volume IDs that are not associated with the master volume
of a set You may regret it ... the system may fail.
volumeid# ... lists information about the specified volume ID
(a 16-bit hex nu
ALL lists information about all volume sets.
DUMP walks the XM logid pool and lists all entries it finds.
BOTH implies ALL and DUMP.
SERVERS [[ALL | SOME | #] [options] ]*
options ::= [noVerbose]
SERVERS ALL will list all xm_static_checkpoint_server
processes. For each such process, it will attempt to
display the most recent "work" message XM has sent to it,
which might mean displaying the LDEV of the the master
volume of the set the work message was for.
The ALL option says: check all processes to see if they
are XM servers.
The SOME option says: check processes 2..32 to see if they
are XM servers. (Usually, PINs 17..21 are the servers.)
The # option says: check the specified PIN to see if it is
an XM server.
The Verbose option dumps more information.
Default: ALL
SET_RESET [options]
options ::= < noDEBUG1 | noDEBUG2 | noPAGING |
noRESET | noSET | noTIMES | noVerbose
SIZES [<noQuiet | noVerbose]>
SSMS [noVerbose]
Causes XMSTUFF to call xm_checkpoint_ssm_maps for every
mounted volume set.
USEq [options]
options ::= < noUSEQQ | noUSEQ | noQuiet |
noQUIETError >
VERsion
Reports the version of XMSTUFF.
XMGlobals
Lists some global XM (Transaction Manager) information.
