Startup Parameter Descriptions : Time Stamp (-tstamp)

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.
