Temporary fix

Comments

• SYSPROC.DSN_WLM_APPLENV and DSNTWLMB are enhanced to support
  the removal of a WLM application environment from an
  existing WLM service definition and install the modified
  service definition, with a further option to activate it.
  
  To remove a WLM application environment using DSNTWLMB,
  set the ACTION parameter to REMOVE or REMOVE_IF_EXISTS
  or REMOVE_ACTIVATE or REMIFEXISTS_ACTIVATE, and set the
  SYSIN WLMNAME parameter to the name of the WLM application
  environment to be removed. If REMOVE_ACTIVATE or
  REMIFEXISTS_ACTIVATE is specified, set the POLICY parameter
  to the service policy to be activated or to 'ACTIVE' if the
  current active service policy is used.
  
  To remove a WLM application environment using DSN_WLM_APPLENV,
  set the input ACTION parameter to REMOVE or REMOVE_IF_EXISTS
  or REMOVE_ACTIVATE or REMIFEXISTS_ACTIVATE, and set the WLMNAME
  option in the input WLMOPTIONS parameter to the name of the
  WLM application environment to be removed. If REMOVE_ACTIVATE
  or REMIFEXISTS_ACTIVATE is specified, set the input POLICYID
  parameter to the service policy to be activated or to
  'ACTIVE' if the current active service policy is used.
  
  If REMOVE or REMOVE_IF_EXISTS is specified, the specified WLM
  application environment is removed from an existing WLM service
  definition, the modified service definition is installed, but
  the service policy is not activated. The removed WLM
  application environment becomes unavailable on the next
  activation of the service policy.
  
  If REMOVE_ACTIVATE or REMIFEXISTS_ACTIVATE is specified, the
  specified WLM application environment is removed from an
  existing WLM service definition, the modified service
  definition is installed, and the service policy is activated.
  
  If REMOVE or REMOVE_ACTIVATE is specified, a return code
  of 8 is returned by both DSNTWLM and DSN_WLM_APPLENV if the
  WLM application environment to be deleted does not exist.
  On the other hand, if REMOVE_IF_EXISTS or REMIFEXISTS_ACTIVATE
  is specified, a return code of 4 is returned by both DSNTWLM
  and DSN_WLM_APPLENV if the WLM application environment to be
  deleted does not exist.
