4 Abstract > Are your disaster recovery procedures a disaster? Attend this session to learn how to use CA 7 Workload Automation (CA 7) tools help develop your disaster recovery plan. Find out how CA 7 Workload Automation Disaster Recovery Modes and Classes can be the key to helping you survive the next disaster. 4

5 Agenda > What is disaster recovery? > Disaster Recovery Options > Recovery from schedule outage > Recovery from non-scheduled outage > Other CA 7 Disaster Recovery features 5

6 What is Disaster Recovery? > Ability to provide seamless, continuous processing > Requires planning/execution of plan 6

7 Disaster Recovery Options > Disaster Recovery Mode Feature added in r11.0 to reduce the number of jobs executed during a disaster Can start CA 7 in this mode (DRMODE=YES parm) Change to DRMODE while running (/DRMODE command) Two new initialization file statements DRMODE DRCLASS > When running in disaster recovery mode: Schedule scan skips jobs in inactive DRCLASS Predecessor jobs in inactive classes option Triggering of inactive classes option 7

12 Recovery From a Scheduled Outage 12

13 Recovery from a Scheduled Outage > Assure that queue/support files are large enough to handle backed-up workload FJOB DRMODE= DRCLASS= /DISPLAY,Q=ALL 13

14 Recovery from a Scheduled Outage (cont) > Quiesce CA 7 job submission STOP,Q=ALL SSCAN,TIME=0 14

15 Recovery from a Scheduled Outage (cont) > Note the NEXT SCAN PERIOD START TIME from SSCAN command output CURRENT SCHEDULE SCAN VALUES SPAN = 240 INCREMENT = 120 QUEUE DWELL = 30 APC.LV1CA7.CA7R1101.JCLLIB SKELETON RETRY = 0 REPROMPT = 10 LEAD TIME = 0 STATUS: REQQ IS ACTIVE ABR MSGS = NO RDYQ IS ACTIVE HOLD JOBS = NO NEXT SCAN WAKE-UP = AT 3679 NEXT SCAN PERIOD START TIME = yyddd AT hhmm 15

16 Recovery from a Scheduled Outage (cont) > Shutdown CA 7 /SHUTDOWN,Z5 CA QUEUES SUCCESSFULLY UNLOADED > Dump the CA 7 primary and secondary log files 16

17 Recovery from a Scheduled Outage (cont) > If the restart time is before the noted NEXT SCAN PERIOD START TIME, restart CA 7 S CA7ONL,TYPE=MOVQ (if queues or checkpoint file reallocated)-- S CA7ONL,TYPE=MOVQ,DRMODE=YES if wanting to start 7 in DR mode CA QUEUES SUCCESSFULLY RELOADED 17

18 Recovery from a Scheduled Outage (cont) > If the restart time is after the noted NEXT SCAN PERIOD START TIME, change INIT file settings and restart CA 7 RUNOPT=NSTA on the INIT statement STOPQ=YES on the SCHEDULE statement Ensure that CA 7 can handle the possible backlog Decide if you want to run in DRMODE S CA7ONL,TYPE=MOVQ or S CA7ONL,TYPE=MOVQ,DRMODE=YES if you want to start CA 7 in DR mode CA QUEUES SUCCESSFULLY RELOADED START,Q=ALL command to start job submission SSCAN commands to set date/time and turn on scan 18

19 Recovery From a Non-Scheduled Outage 19

20 Recovery from a Non-Scheduled Outage > Retain CA 7 log files if possible SASSHIS8 08 report to recreate browse messages SCN0-11 SCHEDULE SCAN STARTED AT hh:mm:ss ON yy.ddd ***** SCAN PERIOD OF yy.ddd AT hhmm THRU yy.ddd AT hhmm ***** > Recovery Aids Program Last Logged Status of Jobs Report Generated Batch Terminal Interface Commands Report Simulated LQ Display of Jobs Report 20

21 Recovery from a Non-Scheduled Outage (cont) > If outage is DASD related and queue files or the checkpoint data set have to be reallocated, start CA 7 with TYPE=FORM otherwise, use TYPE=ERST Ensure that CA 7 can handle the possible backlog Decide if you want to run in DRMODE START,Q=ALL command to start job submission SSCAN commands to set date/time and turn on scan RUNOPT=NSTA on the INIT statement STOPQ=YES on the SCHEDULE statement 21

22 Recovery from a Non-Scheduled Outage (cont) > If normal processing is to occur from this point Execute BTI job with output file from the Recovery Aids program (if FORM start was required) START,Q=ALL to start job submission SSCAN commands to set date/time and turn on schedule scan 22

23 Recovery from a Non-Scheduled Outage (cont) > If only a subset of the processing is to occur DRMODE? HOLD,Q=ALL SSCAN,SCAN=HLD DEMAND new work as required Release queue records when ready to process them 23

24 Other CA 7 DR Features > Dormant Copy of CA 7 > Database Transportability 24

25 Session Summary CA 7 can be a very effective tool in restoring batch processing after a disaster. 25
