Migrating to Host-Based DTC Management
The migration process has been designed from the view that you will be migrating your HP e3000 host from
PC-Based management to Host-Based Management. The process described below assumes that you will be
merging the configuration of your DTCs from OVDTCMgr PC and the PC-based tree of the NMCONFIG file into
the Host-based tree of the NMCONFIG file. If your system is already configured as Host-based, or you want to
retain some DTCs in the Host-based tree of the NMCONFIG file, the process is documented in “Appendix A” of
the updated Configuring and Managing Host-Based x.25 Links manual.
The Migration process consists of the following major steps. These steps are described in more detail in
Appendix A of the updated Configuring and Managing Host-Based X.25 Links manual.
1. Run the PC Migration tool on the OpenView DTC Manager PC and select the DTCs that are to be
managed on the HP e3000 host. The PC Migration tool will create a file that contains all the NMMGR
Maintenance Mode commands needed to create an equivalent configuration on the HP e3000 host.
2. On the HP e3000 host, remove any DTC configurations from the PC-Based configuration in the NMCONFIG
file that aren’t in use or should not be included in the migration process. Run the DTS Validation and
ensure that there are no Validation errors displayed.
3. Change the configuration to Host-based Management and remove all DTCs that may still exist in the
Host-Based configuration.Run the DTS Validation and ensure that there are no Validation errors
displayed.
4. Transfer the file created on the PC to the HP e3000 host and enter the following commands to use the file
as input commands to NMMGR to create the configuration in the NMCONFIG file.
:file nmmgrcmd=<cmdfile>
:nmmgr
Where <cmdfile> is the file that was transferred from the OVDTCMgr PC.
5. Run the Host Migration tool integrated into NMMGRVER and merge the PC-Based DTCs configured in the
PC-based configuration into the Host-based configuration.
6. Create or modify any profiles that have been assigned to DTC devices if you want to apply customization
to the DTCs devices. The profile names assigned by the migration process will either be a default name
assigned by the PC Migration tool or the profile name that was assigned to the port in the PC-Based
Configuration.
7. Validate the NMCONFIG file and perform any changes needed to resolve any configuration discrepancies
that are found.
8. Use DTCCNTRL to perform a DTS Shutdown and Restart.
