Dear Gurus,
We are using WebSphere adapter for SAP and have a very serious problem. For some reason that doesn´t really concern me SAP Service can be not available for long periods of time. By long periods i mean 2 or 3 hours.
The big problem is that the adapter has a property to retry the conection that can be set from 00 to 99. However there is another property that sets the time between retries.
If you do the math, imagining 1 minute between retries (it is nedeed to be up and running as soon as posible) you get at most 1 and a half hour. Which is way to little time.
What is happening to me is that the adapter goes down after the retries and i find out a lot later that there is no service.
So the big question is: is there a way to retry forever? if not, what do can be done to makesure that the adapter is always up?

Any help on the subject would be greatly appreciated.

thanx in advace.

Federico

You don't say what OS the adapter is running on.

In Windows, you could create the adapter as a service, and configure the service properties to include the additional restart stuff you want. That would at least help.

In unix you could write a simple script that would run in the background and monitor for the existance of your adapter process. If it didn't exist, then you could start it.

Some unixes also have a similar kind of notion to windows services, where you could add stuff to restart things in the same way. You'd have to ask your system administrator about that, though.

Jeff, Thanx for the answer.

We are using AIX. I shall ask the administrators to write that script. It´s not that i lack the trust in our administrators, but i find it hard to depend on them when it is not really an AIX problem.

Still. i am very much surprised ("disappointed" would be a better choice of words) that IBM developers only alow 99 retries? Isn´t the adapter's job to stay alive?
