WWI Service restart after 10000 requests

[Former Member]

Dear All,

Our business is generating around 5,000 MSDS on daily basis.

We have four WWI services working on a central WWI server.

We are working on WWI SP37.

We have observed that after 10,000 requests each WWI service is getting restarted automatically.

I wanted to know, if I can increase this number to lets say 50,000.

And If I can increase, then from where can I increase.?

The problem is, the WWI service is stopped but doesn't restart automatically and hence it creates problem.

When we manually start the service, it gets started but before getting started we need to enter the credentials due to log on failure.

I checked the parameters in CGSADM but could not find anything.

I also tried to search on the net and also on scn forum but could not get any help.

Thank you in advance for your help.

Best Regards,

Aarohi

Dear Aaran

based on your explanation I propose that you should start "OSS dialog". This kind of topic is "nearly" out of scope to get results (in my opinion) in SCN. But I have some questions::

"When we manually start the service, it gets started but before getting started we need to enter the credentials due to log on failure." => if I remember correct; on WWI side there should now with SP37 nothing to be done in context of "credentials". Is this error message related to the WWI part?

Coming back to other statements:

Our business is generating around 5,000 MSDS on daily basis. => I assume we are talking about "final" reports;

We have four WWI services working on a central WWI server. => there is some sizing guide for WWI available on SAP marketplace. This amount of WWI services is "on lower" level.

If you  If you do a small calculation:

5000 requests for final report divided by four and use as number something as 5 - 10 s per final report (including cover sheet etc. etc.):  this should be no "problem" to get it done (roughly 1,5 h to make it happen if my calculation is valid).

Honestky: based on some experience years ago with WWI:  SP37 is the current version (I believe); but sometimes  there are still some "issues". So this is a furthere reason  why OSS dialog is the right option

Good morning,

This auto-restart is a built-in function and should be transparent for you (i.e. no interfere with the performances). On the contrary, I suspect is was implemented to avoid the effects of memory leaks.

anyway, I found were that can be setup (see oss note http://service.sap.com/sap/support/notes/1240591)

<<

By default, the WWI server is now restarted with every 1000 generations. You can configure this value with the RestartServer parameter in the [Global] section of the WWI.ini file.

enjoy the day,
