When using IBM's REORG utility to reorganize a DB2 table that has compressed tablespaces, specify the KEEPDICTIONARY option if the table is being processed by Oracle GoldenGate. This prevents the REORG utility from recreating the compression dictionary, which would cause log data that was written prior to the change not to be decompressed and cause Extract to terminate abnormally. As an alternative, ensure that all of the changes for the table have been extracted by Oracle GoldenGate before doing the reorganization, or else truncate the table.
