    Solutions:
    Applying the appropriate Interim Fix APAR PM49712, or a PTF group containing the APAR (see below), will address this issue.

    For IBM WebSphere Application Server for IBM i operating systems:

    For V8.0 through 8.0.0.1:
  • Apply Interim Fix APAR PM49712

  • --OR--
  • Apply the WebSphere Application Server PTF group which includes Fix Pack 2 (8.0.0.2), or later, (targeted to be available 16 January 2012) according to the PTF group instructions.


  • Note: If you use the Web-based ("live") repository provided by IBM, Installation Manager (IM) will, by default, pick up any recommended Interim Fixes (iFix) when installing WebSphere Application Sever V8 or any of its V8 Service Fix Packs. As a result, the iFix may already be installed. ld bIf you are unsure as to whether or not it is installed, you can check either using the IM GUI by selecting "File->View Installed Packages" or using the IM command line "imcl listInstalledPackages -long".

    For V7.0 through 7.0.0.19:
  • Apply Interim Fix APAR PM49712

  • --OR--
