Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

Time Stamp (-tstamp)

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

Operating system and syntax	UNIX Windows	-tstamp
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Client Connection	–	–	–	–

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

When precompiling a procedure, OpenEdge 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.

Notes: 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 4GL Applications .
