PI63177: SLOW APPLICATION UPDATE FOR WEB MODULES WHICH HAVE MANY WEB-INF/LIB JARS

Fixes are available

APAR status

Closed as program error.

Error description

An update to application metadata will take longer than
necessary because extra resources are extracted while
processing the application metadata. The problem occurs for
applications which have many classes in web module WEB-INF/lib
JAR files.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server                                      *
****************************************************************
* PROBLEM DESCRIPTION: Deployment of applications              *
*                      incorrectly expands files in nested     *
*                      archives.                               *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When deploying an application, a subset of files of
the application are written to the configuration folder
(<PROFILE_HOME>/config) of the server into which the
application is deployed.  The intent is to write only metadata
type files, for example, META-INF/MANIFEST.MF, deployment
descriptors, and other XML type metadata files, while omitting
other files, for example, Java class files.
The problem of this APAR is that extra files may be written.
In particular, Java class files of JAR files in a Web module
WEB-INF/lib folder may be written.
The write of these extra files causes extra overhead.
Deployment processing takes longer.  Extra on-disk storage is
used.

Problem conclusion

The problem occurs because an internal setting which controls
which files are written did not reach deeply nested JAR files.
The setting is initially provided to the root application
archive (EAR file), then passed to nested module archives
(WAR, RAR, and JAR files), then should have been passed to
nested JAR files within the WAR and RAR files.

The problem was fixed by updating the code which saves
application files during application deployment.  The code was
updated to add steps to pass the internal setting from module
archives to their nested JAR files.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.5.5.11 and 9.0.0.2.  Please refer to the
