PQ48653: DELAY WITH JSP UPDATES WITH MULIPLE CLONES SHARING JSP DIRECTORY


APAR

APAR status
Closed as program error.

Error description
With multiple clones sharing a common JSP directory, updates
to those JSPs may not be recognized immediately.
Local fix
Problem summary
Models and clones not serving most recent version of
jsp files.
Problem conclusion
Models and clones share the same temp directory for jsps.
The current version of the code was only updating the version
for the first clone that hit the page. Any other clone would
not see the change in timestamps since the basis for reloading
was the jsp last modified date was older than the compiled
class' last modified date. After the first clone recompiled
the other clones would think that they have the most recent
version and not reload the compiled jsp class.
.
Another issue that was also resolved was the sharing of
the temp directory for clones. An optional property was added
to allow separate directories for each clone.  Since this
is additional overhead, it is suggested only for customer's
that are constantly putting modified versions of jsps into
production in a clone environment.
Please read the readme associated with the defect for
further details or the release notes in which this defect
is released in.
Temporary fix
Placed test fix on wasdoc0/apars/pq48653/353.
Comments
Defect resolves..
1) Models and clones not properly updating classloaders
when jsp's are modified.
2) Option feature of creating separate target directories
for each clone.
