Chapter 7 Maintaining Segments Using Third-Party Products : Required Facilities and Process for Softek TDMF

Required Facilities and Process for Softek TDMF
What is Softek TDMF?
Softek TDMF Storage Management Software is a vendor-independent, non-disruptive software solution that can help perform three critical tasks needed in today’s IT centers:
1.
Swap migrations – move data from one storage volume to another, while data centers maintain full read/write access and response time.
2.
3.
What is Softek TDMF Offline Volume Access Facility (OVA)?
The Softek TDMF Offline Volume Access (OVA) allows for easy processing of a point-in-time (PIT) volume copy. With OVA, data can be read from the offline target volumes while normal processing continues to update the source volumes. Using OVA, for example, customers can copy or backup to tape full DASD volumes and/or the databases on them, creating a PIT-consistent archived copy, without halting updates to those databases for the length of time required for backup jobs or image copies.
Prerequisites
To use Softek TDMF, Mainframe Edition to maintain TIBCO Object Service Broker segments, your system must have the following installed:
1.
Softek TDMF, Mainframe Edition, available from Softek (http://www.softek.com), with the Offline Volume Access (OVA) component.
TDMFIPGM OVA Interface Program
The Softek TDMF Interface program (TDMFIPGM) is used to register each OVA to the Softek TDMF sessions creating (or that did create) the PIT copies. When registration is complete, a user-specified program is invoked via TDMFIPGM. While this program is active, I/O requests from OVA that are directed towards an OVA source volume are redirected to the PIT target volume.
Control statements for TDMFIPGM specify volume serial numbers that are to be included in, or excluded from, I/O redirection. It is also permissible to specify data set names rather than volume serial numbers for the inclusion or exclusion functions. However, the entire volume where such a data set is resident is always included or excluded from the I/O redirection.
TDMFIPGM also intercepts reserve and DEQ requests from the invoked program and modifies these to act on the PIT target device.
Process of Using TDMF OVA to Maintain TIBCO Object Service Broker Segments
OVA can be used to maintain TIBCO Object Service Broker segments while maintaining access to the TIBCO Object Service Broker data. The general process is as follows:
1.
Ensure that the segments to be maintained are ONLINE to the TIBCO Object Service Broker system. This prevents access by a TIBCO Object Service Broker offline utility.
2.
3.
4.
5.
When the Softek TDMF point-in-time copy is complete, issue the UNFREEZE TIBCO Object Service Broker command to get TIBCO Object Service Broker to continue processing.
