Before You Upgrade PowerExchange on Linux or UNIX

Before you upgrade the PowerExchange software, complete the following tasks:

Stop all PowerExchange tasks.

Back up the current PowerExchange installation directory to provide fallback, if necessary.

If you specify the DMX_DIR parameter in the dbmover configuration file, back up the directory to which it points.

If you use CDC, back up the directories that you specified in the following dbmover.cfg parameters:

CAPT_PATH. Specifies the directory that contains the CCT files that hold the capture registrations as well as files for the PowerExchange Logger for Linux, UNIX, and Windows.

CAPT_XTRA. Specifies the directory that contains the extraction maps.

If you use the PowerExchange Logger for Linux, UNIX, and Windows, back up the directory that is specified in the EXT_CAPT_MASK parameter of the pwxccl or dtlca configuration file. This directory contains the PowerExchange Logger log files. If you use a group definitions file, back up the directories that are specified in the external_capture_mask positional parameter of each GROUP statement.

You do not need to back up these directories if you plan to cold start the PowerExchange Logger for Linux, UNIX, and Windows.

Review the prerequisites.
