To start an AOM CTRACE using an external output writer, perform the steps shown in the following example. This example will trace for JOBNAME AOMV2 and for ASID 3F. It is possible to selectively trace up to 16 JOBNAMES and 16 ASIDs.

1. Create a CTRACE writer procedure (named CTWTR in the example).
2. Start the CTRACE writer by issuing the operator TRACE command.

   TRACE CT,WTRSTART=CTWTR

3. Alter the AOM CTRACE by entering the operator TRACE command and replying to the resulting message.

   TRACE CT,ON,COMP=SYSAOM                                          
   *05 ITT006A SPECIFY OPERAND(S) FOR TRACE CT COMMAND.              
   R 5,WTR=CTWTR,JOBNAME=(AOMV2),ASID=(3F),END

4. Display the trace information for SYSAOM.

   DISPLAY TRACE,COMP=SYSAOM  

   You should see a response similar to this example:

   RESPONSE=SYSTEM1                                                   
    IEE843I 17.20.13  TRACE DISPLAY 898                               
            SYSTEM STATUS INFORMATION                                 
     ST=(ON,0001M,00001M) AS=ON  BR=OFF EX=ON  MO=OFF MT=(ON,999K)    
      COMPONENT     MODE BUFFER HEAD SUBS                             
     --------------------------------------------------------------   
      SYSAOM        ON                                                
         ASIDS      003F                                              
         JOBNAMES   AOMV2                                             
         OPTIONS    YES                                               
         WRITER     CTWTR  

5. Restore AOM CTRACE to its normal trace level using the TRACE command.

   TRACE CT,OFF,COMP=SYSAOM                     
   TRACE CT,WTRSTOP=CTWTR   

6. Issue the IPCS CTRACE COMP(SYSAOM) subcommand and use the CTRACE WTR data set as the SOURCE value.

   CTRACE COMP(SYSAOM) FULL LOCAL
