Error description

  • TPC-R incorrectly attempts to read post data twice when servlet
    caching is enabled.
    User could not add storage system (z/OS connection) in the Add
    Storage System panel
    

Local fix

Problem summary

  • For customers running on zOS with WebSphere variants it is
    possible for any page that uses post data (csv import, admin
    page, pairs page, add copysets, add device, etc) that the
    product attempts to read the post data twice when application
    server WebContainer has
    the property enableServletCaching set to "true". This issue
    exhibits itself as an error accessing the page or sending the
    data to the server. The fix is to change the code to override
    the input stream and allow classes that wrap the servlet request
    to still read and post data.
    

Problem conclusion

Temporary fix

  • So as a workaround, edit the server.xml file located under
    <WAS_HOME>/
    \config\cells\<CELL>\nodes\<Node>\servers\<Server>\server.xml
    
    set the following properties to "false":
    <services xmi:type="applicationserver:DynamicCache"
    xmi:id="DynamicCache_1184194176406" enable="false">
    ...
    <components
    xmi:type="applicationserver.webcontainer:WebContainer"
    xmi:id="WebContainer_1184194176406" enableServletCaching="false"
    disablePooling="false">
