Overview

This section helps you to understand how to accomplish pessimistic locking in TAFJ.

TAFJ uses tLockManager or one of the mechanisms for database locking as a lock manager for its needs. tLockManager is a process that runs outside of the database.

You need to use the following syntax to launch the tLockManager:

tLockManager [-p<port>][-m1|2][-i | -jvm= "<jvm_args>" ] [--jmx] [--verbose] [--debug]

Where,

• -p<port> : It specifies the port on which to connect to.
• -i : It is used to run interactively (not in background).
• -m : 1 for normal and 2 for hash
• --verbose : It is used to run in verbose mode.
• --debug : In verbose mode trace debug
The default port is 7425.
