I think you'll find that the initial library list for QZDASOINIT is--
defined by the job description used in the prestart job entry in the
QUSRWORK subsystem definition. This may or may not be the job
description associated with QUSER user profile.
When a JDBC user connects to a prestart job, the user profile of the
job is changed, but the library list is not necessarily changed.
As you have noted, once the library list of the job is changed, it
remains changed through reuses of the job by other users.
A library list is a unique IBMi dimension of JDBC. As such, it is
important to set the library list explicitly any time you are going to
rely on its behavior.
Make that part of your standard.
Quoting Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>:
I ran into an interesting problem regarding library lists and JDBC.
I had a Linux Tomcat programmer define his connection to our iSeries
at V6R1 using the libraries parameter. This changed the user
library list of the QZDASOINIT job. Future connections to this job
held the library list specified in the previous job and did not pick
up the user library list form the job description assigned to the
user profile that logged in.
I have determined that if you do not use the libraries parameter the
user library list is set according to the job description of the
user profile connecting.
This was a frustrating lesson learned when all sorts of jobs either
wrote to development or could not find programs called by triggers.
My question is this: How do you keep something like this from
happening? 1. Do you always specify the library list you need for
your connection or do you always use the job description to control
the library?
I want to define a standard and move in that direction to avoid
library list issues in the future.
Has anyone published a standard they would like to share?
