The EDM Logger was processing data in an archive log data set, but encountered a log record whose internally‑recorded RBA was not the value that was expected. Because each log record has a constant amount of data, 4 KB, the RBA recorded in each record should increase by a constant value of X'1000'. The archive log data set in which this condition was found, the RBA that was expected to be found, and the RBA value that was actually found, are all included in the message. This is most likely the result of an I/O error in reading or writing the archive log data set.
The following actions occur:
Error message identified as PWXEDM172780E issued.
The Logger task that encountered this error ends. If this was a task that was reading log data for a log reader process, this will cause the associated log reader process to terminate as well. If this occurs during initialization of the PowerExchange Logger, the PowerExchange Logger address space will terminate.
Examine the status of the log data set that had the error. Try reading the data set yourself to see if the error is permanent or temporary. If the error seems permanent, you may need to use the corresponding secondary log data set to recreate the failing primary log data set. You can then restart the log reader process that failed, or the PowerExchange Logger itself, if the failure occurred during Logger initialization. If you cannot correct the problem, contact Informatica Corporation Product Support.
