Java Classes Optimization

You must optimize the system .class files for them to perform well on the System i. This only needs to be done once.

You use the CRTJVAPGM command on a single file, an entire JAR file, or an entire directory (using wildcards). There are four levels of optimization you can choose. Unless you have a reason to do otherwise, use full optimization (level 40). The command creates an optimized hidden file for each .class file that is loaded by the System i Java Virtual Machine. For more information about this command, see the System i online help.

Run CRTJVAPGM as a batch process on the following files:

obrun.jar

JT400.jar (you can copy this file from the default location to the Plex directory you created earlier to make the path shorter)
