T4 and Restart

James T Horn — Fri, 09 Oct 2009 20:42:02 GMT

T4$COLLECT .... Version: X-28 IDENT 'X-28'21-May-2008

When I have to restart the system, the T4$COLLECT job is not working through the reboot.

16:32:26) $ Submit/Notify/Restart/Keep/NoPrint/Log=UCSTMP:[T4$SYS.DATA]T4$COLLECT_DEC6 -
DISK$ALPHAES40:[VMS$COMMON.T4$SYS]T4$COLLECT.COM/Queue=T4$BATCH -

/Parameter=("NOW/"+P1_1, "MON/", "T4$BATCH", "EWB0:", "", "60", "UCSTMP:[T4$SYS.DATA]", "9999,9999,9999,0,0,0,N,0,,N,N")
%DCL-W-NOPAREN, value improperly delimited - supply parenthesis
\NOW/\
(16:32:26) $ EndIf

Looks like someone fat-fingered a script.

What are those slash "/" doing there in the
strings "NOW/" and "MON/" ?

Check timestamps and versions for the files?

James,

I believe T4 relies on too much customisation in the scripts. Stuff that should probably be done with site specific callouts, but then I don't expect any significant changes or improvements in the future.

Fix the errors Hein has pointed out. Even then, I've found that interrupting T4 doesn't always do the right thing to cleanup the files and restart the collectors.

Most likely another case of OpenVMS being a victim of its own reliability! Since failures are rare, the recovery code isn't always completely debugged for all cases.

On our site, I've extracted the T4 POST_PROCESS section from T4$COLLECT as a separate procedure. There's a regular job that checks the T4 data area for evidence of an interrupted collections, and performs the post process. We also have a process monitor that will restart a missing collector (since we do a fair bit of destructive testing, we tend to have more than the normal frequency of systems crashed or ripped from the cluster).

Modifying T4 procedures is non-trivial. You'll need a mechanism for merging and distributing your changes into any updates from T4.

While submitting the t4 collector it fails since all the 8 parameters passed into it are
not in correct format. T4$COLLECT.COM is expecting a end time after NOW/ within quote (as a parameter).
I guess someone changed the original T4$COLLECT.COM script. Please check the script for
any modification. If you can post the T4$COLLECT.COM script which you are using now, we
can have a look on it.

Here is the T4$COLLECT.COM file.

Someone definately edited your T4$COLLECT.COM procedure. Mine has the same version listed but a few sections are different ... I'ld say an attempt was made to introduce some sort of monthly arrangement (where your's is X.X):

File SYS$SYSDEVICE:[SCGTS]X.X;1
$ month = f$element(f$cvtime("yesterday",,"month"),"/","/JAN/FEB/MAR/APR/MAY/JUN/JUL/AUG/SEP/OCT/NOV/DEC/")
$ File_name = "SYS$MANAGER:NELL" + f$cvtime("yesterday",,"day") + month + f$cvtime("yesterday",,"year") + ".DAT"
$ Set Command T4$Sys:T4$Aclg
******
File _$1$DGA403:[T4.T4$SYS]T4$COLLECT.COM;1
$ Set Command T4$Sys:T4$Aclg

Time to find the author, or debug 1353 lines of DCL goodness yourself.

I attached the original if you give up ;-)

The "/" is "NOW/" is the intended value. No worry there. That line looks clean.

My guess now is that someone re-defined the SUBMIT command for you.

Check out $ SHOW SYMB SUBM*

Actually the "issues" don't appear to be related to the edits. Amazing what you can get away with and still have DCL work! ;-)
