Prerequisites
Before you continue with the procedures described in this chapter, verify that your
site satisfies the following requirements:
• MC/ServiceGuard must be installed at your site (see the MC/ServiceGuard
documentation)
• DTC Manager/UX software must be properly installed and configured on the
original host system and all potential, “adoptive”, host systems (see
chapter 3)
• the required daemon processes must be properly configured and operational
(i.e. running) on all concerned nodes.
• each connected DTC must be properly configured on the original host (see
chapter 4).
Configuring DTC Manager/UX for high availability
To configure DTC Manager/UX for high availability you must:
• transfer the DTC configurations to each adoptive host and verify that the
DTCs can be managed (owned) by that host
• return DTC ownership to the original host
• create/modify an MC/ServiceGuard package to include DTC Manager/UX.
These tasks are described on the following pages.
Transferring DTC configurations to an adoptive host
To transfer DTC configurations you must export each DTC configuration to a file,
copy this file to the adoptive host, and then import the configuration (contained in
the file) to each adoptive host node.
Note Before you transfer a DTCs configuration file, verify that the DTC is managed by the
original host with the dtcping dtcname command.
