Thanks for the reply.

Initially at application login time this is the wrkobjlck screen dump -

Opt   Job          User         Lock      Status          Scope     Thread

  (There are no locks for the specified object)


Frances, I tried using ALCOBJ. This is the screen dump of wrkobjlck.

Opt   Job          User         Lock      Status          Scope     Thread
      QPADEV0001   QSECOFR      *SHRRD     HELD           *JOB
      QZDASOINIT   QUSER        *SHRRD     HELD           *JOB


The first line (QPADEV0001) is the lock obtained by ALCOBJ. *Excl lock could
not be obtained, so just to illustrate my problem i have obtained a shared
lock.

Here the second lock  (QZDASOINIT) is the lock obtained by the java program.
I have closed all the prepare statements and resultsets. Exited the program.
But the lock remains. I'm still in the application and so the connection is
alive.

Can any one suggest a solution for  this problem ?

Thanks

Cheers
Vijosh

That works as well. Depends on what you are used to regarding ease I
suppose. ALCOBJ OBJ(library/file *FILE *EXCL *FIRST)  should do the trick.
You need to follow up with a DLCOBJ also (whereas with interactive SQL, I
just exit the SQL session).

Actually I couldn't remember the command and so I was being lazy :-)

. . .

Wouldn't an ALCOBJ be even easier?
