Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: JVMSERVER fails to enable and creates   *
  *                      an empty server.xml. A subsequent       *
  *                      attempt to enable the JVMSERVER then    *
  *                      fails due to the empty server.xml.      *
  ****************************************************************
  When starting a JVMSERVER, CICS attempts to populate the
  server.xml. If there is a storage issue, such as a full file
  system, an empty server.xml is created and CICS then disables
  the JVMSERVER.
  
  When this occurs, CICS may not log any useful information to
  explain what went wrong. It also causes any further attempts to
  enable the JVMSERVER to fail due to the empty server.xml.
  

Problem conclusion

• CICS has been updated to attempt to log any errors that have
  occurred as a result of a full file system when attempting to
  create a JVMSERVER's server.xml
