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:
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.
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.
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:
