Agenda for Today Describing the results of a failure of an IMS online system
Brief overview of emergency restart and what the restart options mean
Description of the actions required if ERE fails or is not possible◦ How to identify what was active at the time of failure◦ How to identify and close the open OLDS
Results of a failed IMS system Include◦ OLDS is open

IMS Restart OptionsUse COLDCOMM. when: ◦ Normal ERE failed and messages are not critical to the business◦ Can’t get IMS to rebuild the IMS Queues◦ You have a tool to RE-QUEUE the messages
IMS restarts using the same SUBSYS record◦ Starts with OLDS open or closed◦ Continues DBRC AUTHORIZATIONS already held◦ OPEN OLDS closed and then archived◦ PRILOG closed and new one opened◦ Performs dynamic back-outs for all active PSBs◦ SUBSYS record
START RECOVERY = YES/NO Log start time updated to new timeABNORMAL TERM=OFF
IMS Restart OptionsUse COLDBASE. when: ◦ Normal ERE failed and database updates to be handled by
Batch Backout◦ IMS will maintain the IMS QueuesIMS restarts using the same SUBSYS record◦ Continues DBRC AUTHORIZATIONS already held◦ Dynamic database back-outs bypassed◦ BMP PSB are identifed
Databases STOPPED by IMS and AUTHORIZATIONS released ◦ BKOUT record is written◦ OLDS can be open or closed◦ OLDS Archived on completion ◦ PRILOG record is closed and new one opened

by Batch Backout and the message queues are not required

Steps to Run Manual Back Out1. List the OPEN OLDS. 2. Close the OPEN OLDS3. Find the Active PSBs4. Run Batch Backout5. Restart IMS
Find the OPEN OLDSSSID parameter is needed only if there are multiple IMS systems sharing the RECON as in a data sharing environment.Include LIST.LOG SSID(xxxx) to get the complete PRIOLD history so that when you come to close the OLDS you can see the previous OLDS. (next slide)
