Trail Record Format

Each change record written by Oracle GoldenGate to a trail or extract file includes a header area, a data area, and possibly a user token area. The record header contains information about the transaction environment, and the data area contains the actual data values that were extracted. The token area contains information that is specified by Oracle GoldenGate users for use in column mapping and conversion.

Oracle GoldenGate trail files are unstructured. You can view Oracle GoldenGate records with the Logdump utility provided with the Oracle GoldenGate software. For more information, see Logdump Reference for Oracle GoldenGate.

Note:

As enhancements are made to the Oracle GoldenGate software, the trail record format is subject to changes that may not be reflected in this documentation. To view the current structure, use the Logdump utility.
