Use the COMMENT parameter or double hyphens (--) to indicate comments anywhere within a parameter file. Anything on the same line after COMMENT or double hyphens is ignored during processing. Comments that continue to the next line must be preceded by another COMMENT keyword or double hyphens.
Note:
If any columns in the tables that are being synchronized contain the word "comment," there may be conflicts with the COMMENT parameter. Use double hyphens instead.See Administering Oracle GoldenGate for Windows and UNIX for more information about working with parameter files.
