Overloaded autotask

Postby athan » Thu Dec 09, 2010 10:39 pm

Hello guys!

I am new in automation and I faced a problem and don't find the solution, maybe you can help me.
There was a problem with IMS regions on our system. A DB2 reorg OPC application didn't run properly and it was the root cause of overloading an autotask.
The following message was spamming while the application running:
DFS554A IMSP0033 00047 IMSPMPP OENT001 (1) OENT001 000,3303
If this message comes up automation run a checking rexx which contains a 10 seconds delay.
Unfortunately this message came up thousands while the application was running so the autotask had to do for 4 days!
When an automated LLA was requested through automation after 3 days, the execution delayed 8 hours. :/
The operators got alert about this message but the problem didn't exist when they checked it so they ingnored this and nobody saw the overloaded autotask.
I see that there are some function to check the "health" of autotask: for example TASKMON, TASKUTIL, maybe LIST autotask.
But what can I do when I see that the autotask is overloaded again?
If I restart the autotask the messages can be lost and I think it is a bigger problem as the delayed execution of commands.
I am looking for a solution, maybe there is a method to clean up the autotask. Maybe a rexx checks the messages in autotask and if it find a command more than one after each other, than it could be deleted.

Sorry my bad english I try to illustrate it: :roll:

AUTOTASK messages in buffer:
DFS554A IMSP0033 00047 IMSPMPA OENT011 (1) OENT011 000,3303
DFS554A IMSP0033 00047 IMSPMPP OENT011 (1) OENT011 000,3303
DFS554A IMSP0033 00047 IMSPMPA OENT011 (1) OENT011 000,3303
DFS554A IMSP0033 00047 IMSPMPA OENT011 (1) OENT011 000,3303

LLA REFRESH I1
DFS554A IMSP0033 00047 IMSPMPA OENT011 (1) OENT011 000,3303
DFS554A IMSP0033 00047 IMSPMPP OENT011 (1) OENT011 000,3303
DFS554A IMSP0033 00047 IMSPMPA OENT001 (1) OENT011 000,3303

LLA REFRESH I1

I think in this case red colored commands can be deleted and the autotask will be not overloaded.
But I don't know how to perform this because I don't find any information about this.
I can't even list the messages in the buffer for autotask and I am very confused. I have to solve this asap and I am puzzled.
Please if you have any idea, share it with me. :oops:

Thank you very much in advance!
