Hi...
I understand each queue has a queue file, overflow file and touch file, but I also see files being created starting with S in my queue manager subvolume on Tandem. What are these files?
Thanks,
Craig |

Looks to me like the qmgr's active log files. (don't ever touch, except for archiving when no longer used, if you run linear logging)...

Saper is right, you really don't want to play with those.

Sorry, but I have to contradict, because transactional logs are handled internally by OS and TMF on Tandem. These files (starting with 'S') are channel status files.

Tibor you mean on Tandem the channel status is held in files and not in the corresponding system queue? (or is that a zOS specific thing)

Well, fjb, because you likes the mq internals  look these:
1. a part of the files starting with 'S'
| Code: |
$DISC29> fileinfo drossxqs*.s*
$DISC29.DROSSXQS
CODE EOF LAST MODIFIED OWNER RWEP PExt SExt
SBKQAX00 O 0A 438 26FEB2008 13:44 49,255 UUUU 2 2
SBKQAX01 0A 438 20FEB2008 18:33 49,255 UUUU 2 2
...
SYNCHIDX O 0 34816 06FEB2008 13:41 49,255 UUUU 10 1
|
2. channel status
| Code: |
$DISC29> runmqsc DROSS.QMGR
MQSC >dis chs(BKQA.DROSS.SYNC) saved all
3 : dis chs(BKQA.DROSS.SYNC) saved all
AMQ8417: Display Channel Status details.
CHANNEL(BKQA.DROSS.SYNC) XMITQ( )
CONNAME(BKQA) SAVED
CHLTYPE(RCVR) INDOUBT(NO)
LSTSEQNO(1819) LSTLUWID(47A06F9510039F01)
CURMSGS(0) CURSEQNO(1819)
CURLUWID(47A06F9510039F01) STATUS(STOPPED)
MQSC >
|
3. file content dump (the first file is open, because the channel is running that's why I can't open that)
| Code: |
$DISC29> fup copy DROSSXQS.SBKQAX01,,hex

You can find the LUW ids and message sequences in the file e.g. 1819 = 0x071B
FYI,
