applname ALREADY USING uservar FOR APPC SESSIONS

Explanation

VTAM® issues this message in response to a MODIFY USERVAR command when APPC=YES is specified and applname is already using uservar. Another USERVAR cannot be defined with APPC=YES for this application program.

applname is the name of the application program specified in the MODIFY USERVAR command.

uservar is the name of the USERVAR the application program is already using.

System action

VTAM rejects the command and no changes are made to the USERVAR table. Processing continues.

Operator response

Determine which USERVAR the application program should be using.
  • If the application program is currently using an incorrect USERVAR, then the application program will need to terminate (CLOSE ACB) its connection to VTAM, which will remove all knowledge of the incorrect USERVAR. Once the application program’s connection to VTAM has terminated, then the MODIFY USERVAR command can be issued to define the correct USERVAR and the application program can re-establish (OPEN ACB) its connection to VTAM.
  • If the application program is currently using the correct USERVAR and is :
    • The active supplier of the services represented by the USERVAR, redefine the USERVAR with the MODIFY USERVAR,APPC=YES command.
    • Not the active supplier of the services represented by the USERVAR, no action is required.

System programmer response

If the MODIFY USERVAR command was issued through the program operator interface, determine which USERVAR should be defined for the application program and correct the mechanism that established the incorrect USERVAR definition.
