  10. R2 Where are you ? Where should you be aiming? Spatial User Group 2012 Open World 2012 -> Is the Future too cloudy? PremierSupport Extended Support Sustaining Support Jan2013 RDBMS OUG Conference January 2018 11.2 11.2.0.4 Terminal due ?2013? Indefinite January 2015 11.1 August 2015 Indefinite August 2012 10.2 July 2013 Indefinite July 2010 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 20072006 2005 2004 2003 2002 10.1 January 2012 Indefinite January 2009 9.2 July 2010 Indefinite July 2007

  11. The Bug Life Cycle – Fix in Main Opens a Service Request via MOS (Which patch are you on) Customer has a problem with 10.2.0.5 Problem defined Support Tests10.2.0.5 & 11.2.0.3 BDE Tests 12.1.0.0 – Reviews Passes to Development Fixed on Main (Job Done) Bug Visible on MOS

  12. When a bug does not reproduce • More work for BDE Problem at 11.2.0.3 Start to find the Fix 12.1.0.0 Does not reproduce...

  13. Diagnosis…… • Many spatial bugs are tagged to aid rediscovery. STACK Trace Searching knowledge base, You can do this as well...

  14. Bug Process: RFI’s, BLR’s & PSE’s • In order to obtain a fix in the earlier release, i.e. 11.2.0.2 • BDE files a Base Label Request (BLR) for 11.2.0.2 • For the Version the customer has requested • Automatically a Request For Inclusion (RFI) IE 11.2.0.4 is produced, (IF 12.1 was also production it would do a 12.1 RFI as well, we don't know where you will go next.... • A Merge Label Request (MLR) may be required once the BLR is produced.... ”opatchlsinventory –detail” • FINALLY, a Patch Set Exception (PSE) for Customer’s platform is produced.... • Terms and definitions

  15. The Bug Life Cycle – Getting the fix Fixed on Main (Job Done) Customer Requests Patch for 11.2.0.2 Development produce fixes BDE Files BLR For 11.2.0.2 & RFI For 11.2.0.4 BDE Files PSE for Customer Platform Patch produced

  16. An MLR example…. Bug 5448688 is a MLR of bug 5181800 & bug 5191972 1. rdbms/notes/backport.txt 2. rdbms/src/server/rcv/if/kcrr.h 3. rdbms/src/server/rcv/kcrf.c 4. rdbms/src/server/rcv/krsl.c 5. rdbms/src/server/rcv/kcrr.c 6. rdbms/src/server/rcv/krsf.c 7. rdbms/src/server/rcv/if/krsf.h 8. rdbms/src/server/rcv/if/krsl.h Bug 5611025 is a MLR of bug 5380055 4883174 4953737 5098050 4967266 4395779 5001975 1. rdbms/notes/backport.txt 2. rdbms/src/server/rcv/if/kcrr.h 3. rdbms/src/server/rcv/kcrf.c 4. rdbms/src/server/rcv/kcrfr.c 5. rdbms/src/server/rcv/kcrr.c 6. rdbms/src/server/rcv/krsf.c 7. rdbms/src/server/sqllang/parse/dbsdrv.c 8. rdbms/src/server/txn/if/ktucts.h 9. rdbms/src/server/txn/lcltx/ktb.c • A requested fix plus a fix applied affecting the same modules. Green is No Clash

  17. MLR to PSE Bug 5616780 is a MERGE OF THESE MERGES! FINISHED status 35 1. rdbms/notes/backport.txt 2. rdbms/src/server/rcv/if/kcrr.h 3. rdbms/src/server/rcv/if/krsf.h 4. rdbms/src/server/rcv/if/krsl.h 5. rdbms/src/server/rcv/kcrf.c 6. rdbms/src/server/rcv/kcrfr.c 7. rdbms/src/server/rcv/kcrr.c 8. rdbms/src/server/rcv/krsf.c 9. rdbms/src/server/rcv/krsl.c 10.rdbms/src/server/sqllang/parse/dbsdrv.c 11.rdbms/src/server/txn/if/ktucts.h 12.rdbms/src/server/txn/lcltx/ktb.c Bug 5611025 is a MLR of bugs 5380055 4883174 4953737 5098050 4967266 4395779 5001975 Bug 5448688 is a MLR of bug 5181800 & bug 5191972 FinallyPSEFiled to obtain a one-off fix for Customer’s version on their particular platform. PSE BUG 5616781 filed ended at status 93 Should be status 90

  18. Composite Patching • Prevention of requesting unnecessary BLR/MLR/PSE’s due to fact that there is NO conflict at all towards the PSU in question • The composite patch approach introduced starting from 11.2.0.2.7 + 11.2.0.3.2 • Conflict checking towards composite patches • Attempting a more automated apporach • Make supports life easy opatchlsinventory –detail

  19. Why are we introducing Composite Patches? Currently Cumulative patches have several deficiencies. • Installing a new version of the patch requires a rollback of the currently installed cumulative patch • All overlay patches must be rolled back when a new version is installed • Any overlay patches not included in the new cumulative patch must be reapplied after they are recreated • It’s expensive and time consuming to recreate all the patches • Applying Cumulative patches is slow

  20. When to use a base patch xx.x.0.x.0 • A PSU specific PSE (patch) should only be installed/made/ requested in case there is a conflict towards the PSU. • In case of no PSU conflict at all the base version of the patch should be installed/used (11.2.0.3.0/11.2.0.2.0/…). • KEEP IT SIMPLE

  21. What are Composite Patches? • A packaging format used for Cumulative patches • A model to distinguish each new layer of a Cumulative patch • Replace only the parts of the patch that have changed and are not currently installed on the system • Rollback only the parts of the patch that were previously installed • Reduce the need to roll back overlay patches • Improve patch apply performance

  22. Life gets complex 11.2.0.2.4 11.2.0.2.3 11.2.0.2.2 11.2.0.2.1

  23. Complexity PSE A not conflicting with any PSU# => so base version of PSE 11.2.0.3.0 MLR BC for which B conflicts with C and both not conflicting with any PSU# => so base version of MLR 11.2.0.3.0 PSE D conflicting with PSU#1 => so PSU 11.2.0.3.1 needed PSE E conflicting with PSU#2 => so PSU 11.2.0.3.2 needed MLR FG for which F conflicts with G and G conflicts with PSU#4 implying that a FG MLR is needed on top of PSU#4 (which requires a PSU#4 BLR of F and G) => so PSU 11.2.0.3.4 version needed PSE H is an incorrect PSE, there is only a conflict with PSU 11.2.0.3.1 and no conflict with higher PSU’s, the correct version to install/request/… for this patch is a PSU 11.2.0.3.1 version

  24. Windows does it differently • But can be as complex Note 161549.1 11.2.0.2.4 11.2.0.2.3 11.2.0.2.2 11.2.0.2.1

  27. Terminal release of 11.1.0.7.x PremierSupport Extended Support Sustaining Support Jan2013 RDBMS OUG Conference • Architecture changes in 11.2 make back ports tricky if not impossible [SDO_ANYINTERACT fixes wont backport....] A COMPLEX SDO_ANYINTERACT query performance • 11.1.0.7 Elapsed: 00:41:43.74 • 11.2.0.2, 16 times faster! Elapsed: 00:02:30.27 • Strongly advise move to 11.2.0.3 ASAP 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 20072006 2005 2004 2003 2002 May 2012 Location Intelligence Conference 11.1 August 2015 August 2012 Indefinite

  28. Current Release of 11.2.0.3.X PremierSupport Extended Support Sustaining Support Jan2013 RDBMS OUG Conference • Fixes much of the 10.2, 11.1, 11.2.0.1 and 11.2.0.2 issues…. • sdo_anyinteract 43 secs at 11.1.0.7 to 0.7 of a second • There are some important changes to Oracle Database Patch Sets starting with 11.2.0.2 (refer to Note 1189783.1 for details) • 11.2.0.4 or 12.1 where will you go? • To infinity and beyond? 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 20072006 2005 2004 2003 2002 May 2012 Location Intelligence Conference 11.2 Indefinite January 2015

  29. Optimizer!!! Constantly evolving…. Mass of fixes each release. • Issues 10.2.0.5 and beyond testing will show • Slow Performance when using SDO_RELATE / SDO_FILTER (Doc ID 1268383.1) • Execution plans involving "bitmap conversion to rowids" and "table access full". • Cause Optimizer is not selecting the optimal plan. This is being addressed in a future release There is a workaround…

  30. SDO_RELATE / SDO_FILTER (Doc ID 1268383.1) Workaround… SQL> connect /as sysdba SQL> alter session set current_schema=MDSYS; SQL> DISASSOCIATE STATISTICS FROM INDEXTYPES spatial_index FORCE; SQL> DISASSOCIATE STATISTICS FROM PACKAGES sdo_3gl FORCE; SQL> DISASSOCIATE STATISTICS FROM PACKAGES prvt_idx FORCE; Then be sure either flush the shared pool or bounce the database for the effects to take place

  31. Consider Rapid Application Testing • Been around a while – mature enough to use…. • “Record” production system as it runs… • Great for peak loads… etc. • Replay on test/upgraded system • Patch, change statistics/base lines • Replay again and again…. • Difficult to test spatial systems….
