Problem solving for generic resource

Trace TC level 1, 2 & exception in the ranges AP FA50-FA59, FAB0-FABA and FB87-FB8F.

Messages DFHZC0170 to DFHZC0185 are written to the console and CSNE logs.

Information output by DFHZNAC following BIND failures.

If a dump is produced examine the generic resource status and generic resource flag bytes.

The following symptoms may indicate that an affinity should be ended and has not been.

Generic resource status byte (TCTV_GRSTATUS)

TCTV_GR_REGD (X'80')
This CICS is registered as a member of a generic resource.
TCTV_GR_REGERR (X'40')
This CICS attempted to register as a generic resource member (SIT GRNAME parameter specified) but the attempt was rejected by VTAM.
TCTV_GR_NOTAVAIL (X'20')
This CICS attempted to register as a generic resource member (SIT GRNAME parameter specified) but the level of VTAM was not 4.2 or above.
TCTV_GR_DREGD (X'08')
This CICS was previously a member of a generic resource but has successfully de-registered.
TCTV_GR_DREGERR (X'04')
This CICS attempted to de-register as a member of a generic resource by issuing SETLOGON OPTCD=GNAMEDEL but the attempt was rejected by VTAM.
TCTV_GR_NOTAPPL (X'02')
The GRNAME system initialization parameter was not specified.
TCTV_GR_NOTREG (X'00')
CICS is not registered as a generic resource and has not attempted to register. (Holds this value before registration is attempted, if required.)

Generic resource flag byte (TCSEI_GR)

TCSE_GR (X'80)
Both partners are registered as generic resources. Valid from initial acquire to ENDAFFINITY.
TCSE_GR_NAME_CONN (X'40')
Set on for a generic resource name connection in which TCSESID contains the generic resource name and TCSEX62N contains the member name.

Set off for a member name connection in which TCSESID contains the member name and TCSEX62N contains the generic resource name.

This bit is only meaningful if TCSE_GR is set on.

TCSE_USE_OUR_MEMBER_NAME (X'20')
The partner is using our member name. (An indication that the member name, not the generic resource name must be passed in the BIND).
TCSE_MSG179_ISSUED (X'10')
Message DFHZC0179 has been issued. This message is issued when the secondary SNASVCMG session binds if TCSE_GR is set. It makes clear which is the generic resource name and which the member name of the partner session.
TCSE_CATLG_DONE (X'08')
A defined connection with an affinity has been catalogued.
TCSE_MSG177_ISSUED (X'04')
Message DFHZC0177 has been issued. This message is output whenever an LU6.2 limited resources, LU6.2 synclevel 2 or LU6.1 connection is acquired. It is output when the secondary SNASVCMG session binds. It is intended to alert the user to the fact that acquiring the connection has caused an affinity to be created and gives the NETNAME and NETID of the partner.
