APAR status

  • Closed as program error.

Error description

  • Plug-in uses a buffer size of 8K to read in the header; and on
z/OS the HTTP Server expects the data to be in EBCDIC. If the
header size exceeds 8K, the remaining data is never converted
into EBCDIC.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server V6.1       *
*                  z/OS webserver plugin users                 *
****************************************************************
* PROBLEM DESCRIPTION: Headers greater than 8KB are corrupted  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Headers are read in 8KB chunks. Only the first read was being
converted to ascii for processes so subsequent chunks would be
corrupted when they were converted back to ebcdic since they
were never converted to ascii.

    



Problem conclusion


    

  • The entire header (regardless of size) is now translated into
ascii so the corruption no longer occurs.

APAR PM56981 is currently targeted for inclusion in
Service Level (Fix Pack) 6.1.0.45 of WebSphere Application
Server V6.1.
