Re: apache shared memory
Hello, I already have enabled the Axis2GlobalPoolSize parameter and I have implemented the service. The problem is, that the service works only every third call and I think this is a very strange behavior and I don't see what I have done wrong. Maybe I have a small error, but why it works with the simple server?

And when accessing that shared variable you need to switch to global pool. Please see axutil_allocator.h for details.

Every following call should get the shared variable, add two numbers and store it in the shared variable (setLaenge(int a) in myadd.cpp). The result should look like this: first call 10, second call 19, third call 28 and so on, increasing with nine for every following call. The problem know is that I only get the correct value from the service every third call, but then the right value. For the other calls I always got the same, invalid value. It looks like first call 10, second call -1211088511, third call -1211088511, fourth call 19 and so on. I tested it on two servers with an older and newer apache, having the same behavior, but other incorrect values. If I test the service with the axis simple server everything works fine, but I don't know if I can test the shared memory with the simple server? My question now is: Does anybody knew this behavior? Maybe I have implemented something wrong and attached the service. It would be very nice, if someone can have a look inside my code.

Re: apache shared memory
In your code are you switching to global pool before accessing the shared variable? Honestly speaking I have no time to look at your code. Thanks -Manjula.

Re: apache shared memory
Yes, I make axutil_allocator_switch_to_global_pool(env-allocator); try to get the variable or create and store and and then axutil_allocator_switch_to_local_pool(env-allocator); So I think this is the right way, as every third call confirm.
