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.
- Sessions failing to acquire with message DFHZC2405 "Node not activated".
This may also indicate a setup error.
- Sessions failing to acquire with various instances of DFHZC2411. This
may also indicate that a rule has been violated.
- CICS® fails to register as a generic resource when it has previously been
a member of a different generic resource. Message DFHZC0171 is written to
the console with VTAM® rtncd X'14' fdb2 X'86'.
- Connections autoinstalling unexpectedly. If a non-generic resource is
addressing a generic resource member by its member name this may also indicate
that the first ACQUIRE was issued from the generic resource side.
- 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.)
- 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.
