Increasing WebSphere Integration Developer’s Heap Size
March 30, 2010 1 Comment
Sometimes, when working with WebSphere Integration Developer, you may find that you run out of heap space for its JVM – this will typically result in sudden crashes, and often happens when you have a lot of projects loaded or you’re doing a lot of intensive activity.
In this case, you may want to consider increasing the maximum heap size. Because WebSphere Integration Developer is based on Eclipse, you can do this using the standard Eclipse approach, which is documented on the Eclipse wiki.
Broadly, you’ll want to add some command-line arguments to the WebSphere Integration Developer shortcut. Open the properties of the shortcut from your start menu, and append the following:
-vmargs -Xms512M -Xmx1536M
This will set the initial heap size to 0.5GiB and the maximum heap size to 1.5GiB, for example. You can adjust the value for your needs.
this is greate tip I used to have my Integration developer crash
the problem is that this the IDE taking 1.5 GB and the max memory I have on my machine is 4 the process server is going to be starving if I’m to run it locally
