Re: DLCOBJ not releasing a member

Jim:

(You did not state what version / release of OS/400 or IBM i (i5/OS) this was running on.)

What is your CL program doing, in between the ALCOBJ and the corresponding DLCOBJ?

Sign-off, sign-on, and run the following experiment in an interactive job:

1. create a test member "A" in your QTXTSRC file, e.g. using SEU
2. issue "ALCOBJ ((library/QTXTSRC *FILE *EXCL A))"
3. issue DSPJOB and take option 12. Display locks
4. next to the line that shows the file level lock for QTXTSRC, type a
5=Display member locks
5. issue "ALCOBJ ((library/QTXTSRC *FILE *EXCL A))" again
6. issue DSPJOB option 12, then type a 5 next to the file "QTXTSRC"
* notice there are now "two" sets of locks for the MBR and DATA
7. issue "DLCOBJ ((library/QTXTSRC *FILE *EXCL A))
8. issue DSPJOB option 12, then type a 5 next to the file "QTXTSRC"
* notice there is now only one set of locks for the MBR and DATA
9. issue "DLCOBJ ((library/QTXTSRC *FILE *EXCL A))" again
10. issue DSPJOB, option 12 - there should be no more QTXTSRC locks

Do you know see how you might have somehow encountered a scenario that could have left a lock on that member?

For example, perhaps your program encountered an unmonitored error between the ALCOBJ and DLCOBJ and exited, without removing the lock...

Hope that helps,

Hi All

In a cl program, I am issuing the following command to lock a member in a
file. In case it matters the srctype of the file is TXT.

ALCOBJ OBJ((&LIBRARY/QTXTSRC *FILE *EXCL &PROGNAME)) WAIT(&WAIT)
monmsg(cpf1002)

If the member is all ready locked, the the test fails and we have to
release the lock on the member before continuing. All well and good.

Later I issue
DLCOBJ OBJ((&LIBRARY/QTXTSRC *FILE *EXCL &PROGNAME))
no monmsg after
no errors, nothing in the joblog, but the member remains locked.

Work with Member Locks
System:
File . . . . . : QTXTSRC Type . . . . . : PHY
Library . . : INTQAT ASP device . . : *SYSBAS


Lock
Opt Member Job User Type Lock Status Share
JDCPKKKK QCTLD1 JHORN MBR *SHRRD HELD
DATA *EXCL HELD

The lock is not released until I sign off the workstation. As if I had
not issued the dlcobj command at all.

Any ideas?

Jim
