PowerExchange now performs a checksum test of records in the CDCT file of the PowerExchange Logger for Linux, UNIX, and Windows to detect corrupted records and to avoid potential errors while reading information from the CDCT file.
The addition of checksums to the CDCT file makes the file incompatible with PowerExchange releases earlier than 10.2 HotFix 2. Before you apply 10.2 HotFix 2, back up your existing CDCT file. Then, if you need to fall back from 10.2 HotFix 2 to the earlier release, you can restore the CDCT file from the backup.
