Re: JDBC lock after update

This will get you around the problem, but I think it is going to really
tank performance of anything but a trivial application.  The problem with
this change is that  you are going to pay the price of job creation on
every connection.

The suggested solution should work for getting around the problem, but a
better long term solution should be used.  I will request this be looked at
by someone here.

Shahar,
Try this..,
1. CHGPJE SBSD(QSERVER) PGM(QZDASOINIT) MAXUSE(1)
   (the supplied default is 200 for the MAXUSE parameter)
2. Restart the QSERVER Subsystem.

This will release all the object locks when the Database connection is
terminated.

Subject:  JDBC lock after update



Hi all,

I have an application that uses the toolbox jdbc
driver to connect to the as400 database.

When doing select for update, and rs.next i can clear
all locks obtained by QZDASOINIT server job by closing
the result set (rs.close).

When i update a row by using 'update f set fld=value
where keyfld=unique value' the row is updated but the
QZDASOINIT retain a read lock on the updated record.

Is there a way to get rid of the read lock which
remains after the update ?

Thanks for any input
