Hi all,

I developed custom connector to connects my application through WBI ICS 4.3 (running on Windows 2003). Every thing is ok except the amount of memory consumed by connector. Typically it required about 250M-300M. This fact leads me to write "dummy connector" that does not do any activity just to test the amount of memory it consumed and to checks that the code I wrote for my real connector does not cause that excessive memory usage . I found that the amount of memory is also about 200M-250M. This is large amount of memory in my system where I have more than 6 connectors.

Trying to lower JVM max heap size does not contribute to any significant decreasing amount of memory usage. And I do not found any connector configuration properties that configure about connector memory usage.

Any suggestions about memory required by a connector or there may be configuration for it?. My connector written in java.

Thanks in advanced.

How did you find that your connector is consuming memory in the 200-250 range?

Under Windoze, there are Java options set to -mx512m (maximum heap size) and -ms256m (initial heap size) for the "...\WebSphereAdapters\bin\start_adapter.bat" and "...\WebSphereAdapters\bin\start_connector.bat" scripts, depending on which you're using.

I believe these will override anything you might set in your actual adapter start file!

If you want separate memory settings for each adapter, you'll have to set up a separate start_xxxxx.bat for each of your adapters. I'm trying to decide which I want to do...
