Migrating to Host-Based Management
In order to ease the transition from the OVDTCMgr PC-Based solution to Host-Based management, the
following features are available and these behaviors occur when your system is updated to the new
host-based versions of the DTS subsystem.
• Athough it is now an unsupported configuration, the OVDTCMgr platform still is able to manage the
DTCs for connection to the HP e3000. HP recommends that you migrate your DTS configuration to
Host-Based management at the earliest opportunity.
• When you reboot your system after updating with this release, DTS recognizes that the data in the DTS
subsystem of the NMCONFIG file is the old format but still creates a valid DTS configuration. DCC
displays the following warning message:DCC WARNING P-L, NMCONFIG is previous version. Run
NMMGRVER. (DCCWARN 52) The DTS configuration created is identical to what was created prior to
the update.
• In NMMGR, if you attempt to display the DTS configuration before running NMMGRVER, a screen
states that the DTS subsystem has been updated. From this screen you can launch NMMGRVER to
perform the conversion of the NMCONFIG file without exiting NMMGR.
• You use the version of NMMGRVER installed with this release to update the NMCONFIG file to the
latest format and then perform a DTS Shutdown and Restart.
• After using NMMGRVER to migrate the configuration file to the latest format, DTS Dynamic
Configuration will be disabled until a DTS Shutdown and Restart or system reboot is performed.
The PC and Host Migration Tools
The New Host-Based DTC Management release contains two tools that allows you to migrate a majority of
your DTC’s configurations from the OVDTCMgr workstation and the PC-Based NMMGR configuration on the
host to the new Host-based DTC Management in the NMCONFIG file.
Before you perform the migration, you should read the section “Configuration Issues to Consider Before
Migrating” in the updated Configuring and Managing Host-Based X.25 Links manual. Review your
configuration on the OVDTCMgr platform and any HP e3000 hosts that use those DTCs to determine if there
are any configuration changes that you can make to help the process go smoothly. It is likely that you will
need to perform some manual changes to the resulting configuration file to create a valid DTS configuration
and to reapply your DTC port profile customizations.
These tools and the process for migrating your configuration are fully documented in the updated release of
the Configuring and Managing Host-Based X.25 Links manual.
The PC Migration Tool
A PC Migration tool has been created that allows you to migrate your DTC’s configuration from the
OVDTCMgr PC platform to the NMCONFIG file on the HP e3000 host. This tool is incorporated into a patch
to the OVDTCMgr. The PC Migration tool is accessed from a new command that has been added to the
Manage Multiple DTCs Tool menu.
The OVDTCMgr patch is available as part of this Release 7.5 PowerPatch 2 installation. The patch consists of
the following two files:
• READHD45.DTS0000.TELESUP
• EXEHD45A.DTS0000.TELESUP
