SVSODR= parameter for procedures
Use the SVSODR= parameter in procedure to specify options for processing shared VSO areas at a remote site. This parameter is optional. Valid values are NONE, AUTO, DRRS, and WTOR. The default is NONE.
The options take effect during an emergency restart or first area open after an emergency restart when IMS connects to and creates a structure for a shared VSO area.
- NONE
- Specifies that processing is unchanged from existing shared VSO emergency restart processing. This is the default.
- AUTO
- Specifies that during emergency restart or first area open after an emergency restart, if IMS connects to a new structure for a shared VSO area, that area is automatically marked as recovery needed in the RECON data set. If the connection is made to a failed persistent structure, processing continues as normal.
- DRRS
- This option is specified for a system that is to be restarted at the disaster recovery remote
site. Typically, when an emergency restart occurs at a remote site, the connection creates a
structure and the areas need to be marked as recovery needed in the RECON data set.
However, when the DRRS option is specified, IMS recognizes that the emergency restart is at a remote site and processes accordingly. During area-open processing for a shared VSO area, IMS does not attempt to connect to shared VSO structures. The areas are marked as recovery needed in DBRC. Specifying this option saves the overhead of doing a connect and then a disconnect for each shared VSO area.
- WTOR
- Gives the user the option of marking shared VSO areas as recovery needed. During an emergency
restart or first area open after an emergency restart, IMS connects to a shared VSO structure. If
the connection creates a structure, a WTOR is generated. The prompt then gives the user the option
of continuing to process with the new structure or marking the area as recovery needed. Based on the
reply to the WTOR, IMS processes accordingly. A WTOR is issued for each shared VSO area that is
opened during an emergency restart or first area open after an emergency restart when the connection
creates a structure.
The WTOR message is:
DFS2853A A NEW STRUCTURE WAS CREATED FOR AREA AAAAAAAA. REPLY'C' TO CONTINUE OR 'R' TO RECOVER
