Time Stamp (-tstamp)

Use Time Stamp (-tstamp) to direct the AVM to use time stamp information rather than cyclic redundancy (CRC) values to enforce consistency between r-code and schema.

Note: Progress Software Corporation recommends that you use CRC instead of time stamp.

When precompiling a procedure, the AVM inserts in the r-code file a list of referenced tables and their cyclic redundancy code values (CRCs) by default. At run time, OpenEdge compares the CRCs in the r-code to those in the database being run against. If the CRCs do not match, OpenEdge returns an error message.

To use time stamp values rather than CRC values, specify Time Stamp (-tstamp) for the process that compiles the procedures.

The Time Stamp (-tstamp) parameter only applies to a single database.

For more information on time stamp and CRC values, see OpenEdge Deployment: Managing ABL Applications.
