Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Web Server plugin generation takes a * * long time. * **************************************************************** * RECOMMENDATION: * **************************************************************** During Web Server plugin generation, OSGi applications component must contibute information for the plugin. In order to do this it needs to iterate over all the applications installed, but it is only interested in OSGi applications rather than JEE applications. There is no way for it to distinguish between the two types prior to reading the data from the disk which is slow. If there are many JEE applications a significant overhead is incurred by reading JEE applications from disk when that data is of no interest to OSGi applications.
Problem conclusion
This APAR improves the performance of plugin generation by enabling OSGi applications to read only OSGi application data from disk. If there are many JEE applications then this results in a significant performance improvement by eliminating the needless I/O overhead. The fix for this APAR is currently targeted for inclusion in fix pack 8.0.0.7 and the fix pack 8.5.5.1.
