TPX100 INITIALIZATION ERROR: SETLOGON GNAME FAILURE, RC=10 19 


TPX LOG displays the following details. 
RC 10, 19 on GADD (SETLOGON OPTCD=GNAMEADD)

Explanation of Return Code.
RTNCD FDB2 Explanation :: - 16(X'10') 25(X'19') Host is not member of Sysplex

Environment

Release : 5.4
Component : CA-TPX for Z/OS

Resolution

The application issued either the
- INQUIRE OPTCD=SESSNAME,
- the CHANGE OPTCD=ENDAFFIN, or
- the SETLOGON OPTCD=GNAMEADD | GNAMEDEL | GNAMESUB macro instruction,
  but the coupling facility for this host is inaccessible.

The coupling facility might be inaccessible because:

• A coupling facility does not exist.
• A CFRM policy for the required coupling facility structure was not active.
• VTAM is not defined as an APPN node.
• VTAM has lost connectivity to the required coupling facility structure.
• For TPX GR/CF structure to work, the IBM SYSTEM CF (ISTGENERIC) MUST be available. Refer to IBM manuals for detais.
