Explanation
VTAM® issues
this message in response to a DISPLAY ID command for an application
that supports persistent sessions.
- This message is displayed with type=SNPS when:
- The application is found on the VTAM on
which the command is issued and the application has indicated that
single node persistent (SNPS) forced takeover requests will be accepted,
but that multinode persistent (MNPS) forced takeover requests will
not be accepted.
- An application that supports MNPS is specified, the application
is found in the MNPS coupling facility structure, and the application
has indicated that SNPS forced takeover requests will be accepted
for this application, but that MNPS forced takeover requests will
not be accepted.
- This message is displayed with type=MNPS when:
- The application is found on the VTAM on
which the command is issued and the application has indicated that
multinode persistent (MNPS) forced takeover requests will be accepted,
but that single node persistent (SNPS) forced takeover requests will
not be accepted.
- An application that supports MNPS is specified, the application
is found in the MNPS coupling facility structure, and the application
has indicated that MNPS forced takeover requests will be accepted
for this application, but that SNPS forced takeover requests will
not be accepted.
This message indicates the support level that was last
requested by the application. An application must still be enabled
for persistence before a forced takeover will successfully complete.
See z/OS Communications Server: SNA Programming for more information on enabling an application
for persistence, and for information on forced takeover processing
in general.
type specifies one of the
following values:
- MNPS
- Indicates that multinode persistent forced takeover requests are
permitted, but single node persistent forced takeover requests are
not permitted.
- SNPS
- Indicates that single node persistent forced takeover requests
are permitted, but multinode persistent forced takeover requests are
not permitted.

System programmer response
If the setting displayed is not correct,
modify the application behavior so that when SETLOGON OPTCD=PERSIST
is issued by the application, the correct value for the PARMS=(FORCETKO=)
operand is specified.
