Chapter 8 Recovery Procedures : Full Recovery Procedure

Full Recovery Procedure
The tasks to perform a full recovery are as follows:
These tasks are described in detail in the following sections.
 
Task A Shut Down the TIBCO Object Service Broker System
For detailed instructions about shutting down TIBCO Object Service Broker, refer to TIBCO Object Service Broker for z/OS Installing and Operating.
Task B Create a Data Set Containing the Latest Page Images
These page images are used to restore the damaged segment.
For Recovery up to Your Last Checkpoint:
1.
2.
3.
4.
5.
Run the S6BBRPTR (Batch Pointer Check) utility using the point-in-time restore file as input and check ERRLOG for any messages.
6.
If the S6BBRPTR utility runs cleanly, delete, define, and reformat the page data sets in the segment to be restored and use the restore file to restore your segment.
For Recovery up to a Point in Time:
For each Segment you want to restore to a point-in-time:
1.
2.
Using the S6BTLSRP (Select Recovery Pages) utility and all necessary Journal accumulation files as input, create a file that contains the latest page images up to the designated point-in-time.
3.
4.
Merge the file created in the previous step with the appropriate segment backup file to create your point-in-time restore file.
5.
Run the S6BBRPTR (Batch Pointer Check) utility using the point-in-time restore file as input and check ERRLOG for any messages.
6.
If the S6BBRPTR utility runs cleanly, delete, define, and reformat the page data sets in the segment to be restored and use the restore file to restore your segment.
Task C Rebuild Each Segment
Delete and Redefine the Data Sets
1.
Use IDCAMS DEL/DEF to delete and redefine all the data sets in the specified segment.
2.
3.
Initialize the Data Sets
1.
Follow the documentation within the JCL to specify this.
2.
To reduce elapsed time, you can initialize page data sets asynchronously by running parallel jobs that each contain a DD statement for a different page data set.
Task D Restore the Data Sets
1.
The member RESTORE in the JCL data set, distributed with TIBCO Object Service Broker, contains sample JCL to restore a segment from a TIBCO Object Service Broker system backup.
2.
3.
4.
Follow the documentation within the sample JCL to specify this.
5.
After executing the JCL to restore the data sets, the data is copied from the backup tapes to the specified segment.

Task E Rebuild the Recovery Data Sets
The recovery data sets are the redolog, the contingency log, CACHE1, and CACHE2.
The following procedure destroys any recovery data that is still in recovery data sets. Be sure to assess the consequences of losing that data. If you are not able to do a clean shutdown of the Data Object Broker, you lose any updates since the last complete checkpoint.
Delete and Redefine the Data Sets
1.
2.
3.
Initialize the Data Sets
1.
2.
3.
This job calls the following utilities:
Task F Restore TIBCO Object Service Broker
For detailed instructions about starting up TIBCO Object Service Broker, refer to TIBCO Object Service Broker for z/OS Installing and Operating.
If the system was backed up using a DASD backup product such as DF/DSS or FDR, it must be restored in the same way as other DASD backed up using that product. This requires that it be restored using the same device type from which it was backed up.
