PQ83111: WebSphere Application Server 4.0 tuning guide should be changed with regards to number of JNI Readers for a 2 processor system.

APAR status
Closed as documentation error.

Error description
The WebSphere Application Server 4.0 tuning guide at the
following link should be modified:


http://www-106.ibm.com/developerworks/websphere/WASInfoCenter/in
focenter/wasa_content/0901.html#b257

Under 'Using JNI ReaderManager and ReaderThreads -> How to view
or set -> In the Command Line Arguments field -> Note'
the guideline should be changed to reflect the fact that the -Dc
om.ibm.CORBA.numJNIReaders=xx parameter should be set to a
minimum of the number of processors available in the system
+ 1.

The customer followed the guideline as currently written and
experienced a failure.  When he increased the xx parameter by 1,
he did not experience the failure.
