eFix (APAR): PQ52901
Status:      eFix

For Release: WebSphere 4.0.1

For Operating System: all

CMVC defect: PQ52901

Required eFixes: PQ52901 INTERRUPTED RESPONSE NOT HANDLED CORRECTLY (co-requisite).

Byte size of APAR: 860,263 bytes

Abstract: INTERRUPTED RESPONSE NOT HANDLED CORRECTLY

Description/symptom of problem: 
When the client prematurely closes the connection, all buffered writes must
be cleared appropriately.  The engine was catching I/O exceptions and not
allowing the output buffer to be cleared.


Directions to apply efix:

1) Create temporary "efix" directory to store the zip/tar file:
             AIX: /tmp/WebSphere/efix
   Solaris/Linux: /tmp/WebSphere/efix
         Windows: c:\temp\WebSphere\efix

2) Copy zip/tar file to the directory

3) Unzip/untar the file

4) Shutdown WebSphere

5) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar PQ52901_eFix_AEServer_AEsServer.jar

6) Restart WebSphere

7) The temp directory may be removed but the zip/tar file should be saved.  Do not remove 
   any files created and stored in the <WASHOME>/WebSphere/AppServer/efix/PQ52901 directories.
   These files are required if an efix is to be removed.



Directions to remove an efix:

NOTE:  EFIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE AN EFIX UNLESS
       ALL EFIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED EFIX.

Example:  If your system has efix1, efix2, and efix3 applied in that order and efix2 is to be
          removed, efix3 must be removed first, efix2 removed, and efix3 re-applied.


1) Change directory to the efix location (<WASHOME>/WebSphere/AppServer/efix/PQ52901).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
   java -jar PQ52901_eFix_AEsServer_AEServer.jar

4) Restart WebSphere

5) To enable view the additional information provided below.


Directions to re-apply an efix:

Follow the instructions for applying an efix.  If the backup files still exist (from the 
previous efix application), you will be prompted to overwrite.  Answer "yes" at the overwrite 
prompts.
