RP/TUX 6.4, 6.5, 6.51 - Domains:MP config, migration did not migrate DMADM (Doc ID 767512.1)

Last updated on NOVEMBER 04, 2016

Applies to:

Oracle Tuxedo / Tuxedo / 6.4, 6.5, 6.51
Information in this document applies to any platform

Goal

PRODUCT:  Tuxedo
VERSION:    6.5, patchlevel 227
OS:               AIX 4.3

The application is an MP configuration that implements Domains.  Before the application is migrated, all the services
are advertised successfully.  If 'dmadmin' is run,  then 'pd -d DGW3A' for the local domain name 'DGW3A',  the output
is successful:

Local domain :DGW3A
        Connected domains:

Then, the application is migrated from the Master to the Slave using the commands:

From the Master:
1) tmshutdown -R -l P1 (where P1 is the master LMID)
2) migm P1

Result:  The servers shutdown succcessfully, and the migration is also successful.

However, on the Master, when 'dmadmin', 'pd -d DGW3A' is run again, the following error message is displayed:

CMDGW_CAT:2077: ERROR: Specified Local domain DGW3A not active or not configured

Also, on the Slave machine, the following error messages are written to the ULOG:

165313.lcaix5b!GWTDOMAIN.3960: LIBGW_CAT:3037: ERROR: Can't attach initial shared memory segment to the gateway
process
165313.lcaix5b!GWTDOMAIN.3960: LIBGW_CAT:3015: ERROR: Can't attach to the shared  memory segment(s)
165313.lcaix5b!GWTDOMAIN.3960: LIBTUX_CAT:250: ERROR: tpsvrinit() failed
165316.lcaix5b!restartsrv.17784: server DGW3A/20: CMDTUX_CAT:1684: ERROR: Application initialization failure
165316.lcaix5b!restartsrv.17784: server DGW3A/20: CMDTUX_CAT:587: INFO: Cannot restart server, scheduling for cleanup

Another problem observed is regarding the IPC resources on the slave machine.  When the application is migrated back
to the master, and 'tmshutdown -y' is executed, all the servers shutdown successfully.  However, on the slave machine,
there are still IPC resources existing.
