How to solve deadlocks and timeouts?

[Sathish K]

Hi,

If need to solve the the deadlocks and timeouts in jobs and transactions (IMS DC),what should be the approach?

[Robert Sample]

1. Find out what is executing at the time.
2. For a deadlock, cancel them one at a time until the deadlock goes away.
3. For a timeout, you need more data -- was the time out due to a resource not being available, or a program looping, or what? The solution depends upon the cause.

How do we conclude what all might be executing, we've mainview here but I'm not sure if it can in this and if yes, how can I make use of it.

Consult your site support group. Mainview can handle such problems, and often identify precisely which tasks are having the problems. However, it does require some learning how to use it as well as getting access to the product at your site.

Thanks for the guidance Robert. It's tough to learn these tools.

Yes, using monitors such as Mainview appropriately requires a lot of training since they are complicated tools.
