This fix pack was released on 27 Nov 2018 so it isn’t new but it has some enhancements worth moving to and exploiting. Reads on standby has been improved via reduction in replay window thru a the new variable DB2_HADR_ROS_AVOID_REPLAY_ONLY_WINDOW. The DB2_USE_ASYNC_FOR_MIRRORLOG variable can be used to improve mirror logpath performance by enabling log writing in parallel to the active and mirror log path. The performance of online backups can be improved by using the new DB2_REDUCE_FLUSHING_DURING_BACKUP registry variable by reducing the amount of changed pages that have to be flushed from the bufferpool at online backup startup.
There are a bunch more of improvements, get all the details here: https://www.ibm.com/support/knowledgecenter/SSEPGG_11.1.0/com.ibm.db2.luw.wn.doc/doc/c0061179.html#c0061179__MP4FP4
I get a lot of questions regarding whether or not a clients Db2 version is supported or other questions on extending support. IBM announced the Db2 continuing support program quite some time ago. For a refresher, go to this page https://www-01.ibm.com/support/docview.wss?uid=swg22002945
If you set the DB2_BAR_STATS registry variable to ON additional info will be provided in the db2diag.log. You also get the size so you can track backup size. Nice little Redbook on this and backup performance at http://www.redbooks.ibm.com/abstracts/tips1344.html?Open
I get asked for this information all the time so I thought I would share the link with all of you….

Agenda for December 12, 2018
8:30-9:00 Breakfast & Announcements
Sponsored By Gunning Technology Solutions
9:00-10:15 “DB2 BAR Best Practices”
Presenter: Dale McInnis, IBM
In this presentation we will discuss the options open to customer for DB2 recovery. We will review the options available for different levels of granular recovery, be it object level, tablespace level, node level or DB level. Best practices and what real customers are doing will be discussed.
10:15-10:30 Break
10:30-11:45 “ DB2 HADR Multiple Standby Deep Dive”
Presenter: Dale McInnis, IBM
In this presentation we will look at the details behind running HADR in a multiple standby environment. How does the configuration differ from a single standby and what restrictions are there. Best practices on how to provide automation in the case of a disaster will be examined.
11:45 -1:00 Lunch – Sponsored By: Gunning Technology Solutions
1:00 – 2:15 “DB2 Row and Column Access Control (RCAC)”
Presenter: Phil Gunning, Gunning Technology Solutions
Attend this session to learn how control access to data using RCAC. The Encrypt and Decrypt functions have been deprecated in DB2 10.5 and beyond and RCAC is the new way of protecting columns and rows from unauthorized access. This session will provide examples of how to implement RCAC and how to use groups and roles to protect data. Along with Db2 Native Encryption, this provides a powerful solution to protect your data.
2:15 – 2:30 Closing
If you are planning your migration to Db2 11 you need to pay attention to supported Windows levels….http://www-01.ibm.com/support/docview.wss?uid=swg21665082
Moving from 9.7 to 11? Windows 2008 Server not supported. See the requirements per Db2 Version here: https://www.ibm.com/software/reports/compatibility/clarity-reports/report/html/softwareReqsForProduct?deliverableId=C4F0F2105FF511E6865BC3F213DB63F7&osPlatforms=Windows&duComponentIds=S001%7CS006%7CS005%7CS003%7CS004%7CA002%7CA007%7CA008&mandatoryCapIds=183%7C25&optionalCapIds=30%7C341%7C47%7C17%7C1%7C20%7C28
If you are still relying on snapshots, you might want to take a look at snapshot monitoring views introduced in Db2 9.7. Although Db2 9.7 has been out of support for some time, I find there are many companies still working on moving off it to a supported releases. If you are in this boat, use this Developer works article to get you moving to the new monitoring. https://www.ibm.com/developerworks/data/library/techarticle/dm-1306snapshotmonitoring/index.html
This is a web interface that was announced at SHARE today. Check it out at https://zowe.org/. Zowe
