Hello All,
Would anybody be able to put some light on an issue w.r.t a database update that occurs on a DB2 table.Apparently when I try to do a database update using ESQL, the system locks as in the table freezes and I cant do anything.
I know itis during updation because that is the only data manipulation that occurs in the ESQL.I tried a test insert and it works fine.
Is this anything todo with setting up buffer size for the table or anything in that order from a DB2 point of view or itis more of Message broker settings.
If itis DB2 may be I can ask my admin to look ito that aspect.
Please do share any thoughts on this.
Environment:WBIMB 5.3, DB2 7.2, WMQ 5.4

Thankyou,
Cheers,

Just throwing in ideas..was wondering if there is
Option 1:An esql stmt that would override the transaction level to low...from what I understand there is only 2 levels Commit and Automatic that can be set at the node properties..is there a level below that...
Option 2:An esql to put a break like "wait 10 sec" before the next transaction occurs..
please do give me some directions to go about this situation...
thankyou,
cheers

It would be helpful to know the particulars. Updating as such is usually pretty straight-forward. Post somecode and error messages (if any).
