While the PowerExchange Express CDC for Oracle log reader was running in offline mode, it encountered a redo log file that does not conform to the expected log format because some log header information is missing. In an Oracle RAC environment, this message includes the name of the relevant RAC member.
The log reader ignores the log file and continues log discovery.
In the PowerExchange Express CDC for Oracle configuration file, ensure that the DIR and FILE parameters in the READER statement are correctly specified.
