Hi,

We are sending some messages from MS outlook to Mainframes.
But sometimes the IMS transaction abends with the following error (U0499)

As per IBM documents..

Explanation: The maximum insert call count was exceeded and the
application received an 'A7' status code. The application then attempted
to issue another insert and was terminated abnormally with a U0499.

System Action: The application program is abnormally terminated, and the
PSB is stopped.

Programmer Response: Check the application program and make sure it
recognizes an 'A7' status code, or increase the maximum insert count
specified in the TRANSACT macro at SYSGEN.


Now.. what does this means...

This is the properties of my transaction..

Code:

 QCT   LCT  PLCT CP NP LP SEGSZ SEGNO PARLM    RC
  0     2     3  8  8  9     0  1000  NONE     0 
 

Also.. this issue doesnt happen every time.

Any information on this will be really helpfull..

TIA
Ash..

Hello,

I believe you either need to "increase the maximum insert count specified in the TRANSACT macro at SYSGEN." or reduce the size of what you are sending from Outlook.

Can you verify that the problem occurs with larger messages?

Hi Dick,

Yes it happens only for larger messages... but that too not always.. Strange!!! And yes we cannot decrease the length of the message.

Currently we are splitting the messages into 2 and sending.. but we are looking for a permanent solution..

And how do I know the current insert count specified for this transaction??? is it SEGNO in Transact macro??? if I increase the insert count will it impact the performance of the transaction?? or any other -ve impact?

Thanks
ASH...
