This two-day course begins with the basic concepts of TMF, including business transactions, audited files, locking, audit trails, dumps, and recovery. It then covers the planning and configuring of the TMF subsystem. Students will learn how TMF should be monitored to confirm smooth operations, and how it can be dynamically reconfigured should problems arise. File dumping and file recovery are covered in detail.
In labs, students will explore TMFCOM and Snoop, learn how to manage a tape library, perform a dump and file recovery, and monitor volumes, audit trails, and transactions. Several TACL routines are included with the course to expedite TMF management.
Managing the TMF Environment is based on the G06.20 version of NSK, so the changes in G06.17 TMFCOM are included.
If you use RDF, this course can be conveniently paired with PLRDF301 - Managing the RDF Environment, which is a three-day course. Scheduling the two courses in the same week (with TMF first) will provide students with a complete picture of the closely integrated TMF and RDF environments.
Course Duration: 2 days (on-site)
NonStop system managers, operators, and database administrators. Programmers who develop TMF-based code will also benefit from deeper insight into the TMF subsystem.
TMF protects your most valuable application data. Make sure this critical NonStop product is properly configured and correctly monitored. Should audit trails threaten to fill, be certain you can respond effectively to keep transactions active. Should data be lost or corrupted, ensure you can respond quickly to minimize damage and to restore full application functionality. This course is designed to meet these vital needs.
Students should have approximately one year experience with NonStop system management, including some exposure to TMF. There is no course prerequisite.
