• Start an iSeries command line and enter the following:  
  • WRKOBJ OBJ(PPLBTA<ENV>/TNAPILOG*) OBJTYPE(*FILE)

*Note:  Replace <ENV> with the two character environment designator.

• Does the log file currently exist?
  
  • If No -> go to the CRTPF step 
  • If the name of the file is TNAPILOG 
    • Skip to the CLRPFM step
  • If the name of the file is anything else like TNAPILOG??, the object was renamed at some point to disable the logging, rename it as follows:
    • RNMOBJ OBJ(PPLBTA<ENV>/TNAPILOG??) OBJTYPE(*FILE) NEWOBJ(TNAPILOG)
      
• Start logging with an empty file.  Clear the log file with the following command:
  • CLRPFM FILE(PPLBTA<ENV>/TNAPILOG)
• To ensure the file doesn't fill up and cause errors, enter the following command:
  • CHGPF FILE(PPLBTA<ENV>/TNAPILOG) SIZE(*NOMAX)
    
• CRTPF FILE(PPLBTA<ENV>/TNAPILOG) RCDLEN(80) SIZE(*NOMAX)
  

 Important!  Disable logging as soon as troubleshooting is complete –

To disable logging:

RNMOBJ OBJ(PPLBTA<ENV>/TNAPILOG) OBJTYPE(*FILE) NEWOBJ(TNAPILOGXX)

*Note:  Replace <ENV> with the two character environment designator
