4 Redhat Certification in progress Migration Path to 12c for Redhat. kernel (s390x) (Redhat 7 Update 1) RDBMS on RH7 System z (s390x) (Doc ID ) Published upon completion of certification Oracle RPM Checker ora-val-rpm-rh7-db s390x.rpm on RH7 Installer Issues./runInstaller requires following parameters:- -ignoresysprereqs ignoreprereq -jreloc Software only install do not create DB during installation. Grid Infrastructure Installations: installation Do not run root.sh Apply latest PSU Run root.sh 8

5 Redhat Java issue: Java 1.5 will not run on RH7 coredumps Installer for will not work with default JDK 1.7 on RH7 Need to have JDK 1.6 installed and point to it with jreloc parameter of./runinstaller../runinstaller Starting Oracle Universal Installer... Checking Temp space: must be greater than 80 MB. Actual MB Passed Checking swap space: must be greater than 150 MB. Actual 4095 MB Passed Preparing to launch Oracle Universal Installer from /tmp/orainstall _ pm. Please wait...

10 Overview of Oracle Patching Method to Apply Code Fixes to Oracle Software PSU SPU/CPU Bundle Patch Interim Patch Release Time Quarterly Quarterly Quarterly On Request Definition Security + Recommended Fixes Security Fixes JVM +Security + Recommended Fixes Single Bug *SPU Not available from onward * Bundle Patch- Doc *Combo is just GI/PSU/SPU + OJVM PSU 21

11 PSUAPR Patching Options GI PSU ( ) (includes GI fixes, DB Fixes Security Fixes) DB PSU ( ) OJVM PSU ( ) DB BP ( ) (~500M) Notes: DB BP aka as Quarterly DB Patch (QDP) For Rac and Non Rac Includes BP for DB In-Memory Includes GI PSU and DB PSU 22

12 PSUAPR GI Patching Recommendation use opatchauto e.g. opatchauto apply <stage>/ ocmrf <ocm response file> GI PSU ( ) (includes GI fixes, DB Fixes Security Fixes) DB BP ( ) (Note! very large~500m) Require opatch version GI/ASM binaries must always be at version = > than DB Home OJVM PSU is non rac rolling + startup upgrade (mandatory for all versions) Beware: Always read the READMEs they change between PSUs! 23

13 PSUAPR2015 Combo Patches for OJVM PSU These are simply patches which are zipped together for convenience and ease of download e.g: Patch Combo of OJVM Component, DB PSU + DB BP (Apr2015) Patch Combo of OJVM Component, DB PSU + GI PSU (Apr2015) Patch Combo of OJVM Component, DB PSU + DB PSU (Apr2015) Once unzipped refer to specific Patch readmes on how to install. 24

14 Opatch - Patch Listing : Opatch lsinventory Central Inventory Pointer file (orainst.loc) Central Inventory (inventory.xml) Local Inventory Complete Patch List (comps.xml) 25

15 Patch Listing : Traditional Opatch lsinventory /var/opt/oracle/orainst.loc default location inventory_loc=/grid/orainventory inst_group=oinstall /grid/orainventory/contentsxml/inventory.xml Central Inventory <HOME_LIST> <HOME NAME="OraGI12Home1" LOC="/grid/12102" TYPE="O" IDX="1" CRS="true"/> <HOME NAME="OraDB12Home1" LOC="/oradb/12102" TYPE="O" IDX="2"/> </HOME_LIST> $OH/inventory/ContentsXML/comps.xml - Local Inventory opatch util loadxml -xmlinput <comps.xml> 26

16 Queryable Patch Inventory 12c New Feature Using SQL Query get the list of database patches. OPatch in 12.1 supports inventory in XML Format. Opatch lsinventory - xml Queryable Patch Interface Return XML Type Inventory data is stored in Database tables 27

17 Components of Queryable Patch Inventory Oracle_loader Preprocessor DBMS_QOPATCH External Table 28

18 External Table Oracle _loader View External data as if it were data in a database table. Table isopatch_xml_inv,rdbms/admin/catqitab.sql CLOB (Character Large Object) is an Oracle data type. ORACLE_LOADER Load Data Text Based Default access driver Oracle _loader Preprocessor External Table Preprocessor External Table DBMS_Q OPATCH DBMS_QO PATCH 29

19 Oracle_ loader Preprocessor DBMS_Q OPATCH PREPROCESSOR External Table Preprocessor Program represented by : preprocessor opatch_script_dir:'qopiprep.bat' Converts data to a record format for Oracle_loader.! Yes it is qopriprep.bat! 30

20 Queryable Patch Inventory SQL Interface DBMS_QOPATCH, dbmsqopi.sql Real Time access OUI Patch Inventory PLSQL/SQL interface to view List of patches applied Complete OPatch Inventory SQL Patch Status...and many more DBMS_QOPATCH subprograms GET_OPATCH_LIST GET_OPATCH_LSINVENTORY GET_SQLPATCH_STATUS 31

21 Summarize the Workflow : Database select Select * from from OPATCH_XML_INV OPATCH_XML_INV Oracle Loader Access Driver Preprocessor Opatch lsinventory -xml Select on External table (OPATCH_XML_INV) Preprocessor program opatch lsinventory xml Load/Copy the Data in tables. 32

22 Directory objects required for the QPI: SQL>select directory_name,directory_path from dba_directories where directory_name like 'OPATCH%'; OPATCH_LOG_DIR /oracle/12102/qopatch OPATCH_SCRIPT_DIR /oracle/12102/qopatch OPATCH_INST_DIR /oracle/12102/opatch qopatch_log.log qopiprep.bat 33

24 Overview of Datapatch This is the driver script Automates post-patch SQL actions for database patches. Supports Interim Patches, PSUs and Bundle Patches Determines the pending apply/rollback SQL actions Supports Oracle Multitenant Script Location $ORACLE_HOME/OPatch/datapatch 35

25 Deployment Automation Pre and Post 12c Patches with both Binary and SQL Changes Patch Binaries in $OH using standard OPatch Restart DB and manually complete Restart DB post and install call datapatchactions to complete post install actions (EMCC / OPatchAuto does it automatically) datapatch automatically detects and completes post install actions SQL datapatch SQL 36

26 Logic of Datapatch Post Patch OH Patch List Constant Logic : Datapatch will sync OH and sql patch level DB_HOME/ SID Compare Patch Level Run Apply/ Rollback scripts SQL Patch Registry Table 37 37

27 SQL Patch Registry Table Track the SQL patches applied and rolled back. SQL patch registry table is one per Database. It can put more than one row per patch_id View - dba_registry_history Table :REGISTRY$HISTORY View - dba_registry sqlpatch Table :REGISTRY$SQLPATCH 38

28 SQL Patch Registry Column Name Example (dba_registry_sqlpatch) Patch_id Patch_Uid Action_Time 25-MAR AM Description Database Patch Set Update : LOGFILE STATUS $ORACLE_BASE/cfgtoollogs/sqlpatch/<ID>/ _apply_ORCL_2015Mar3011_19_45.log SUCCESS VERSION Action FLAGS APPLY NB Bundle_Series PSU, Bundle_ID Bundle_data bundle id= 3" 39

29 Which Patch Deployment Method Uses Datapatch? OPatch Opatchauto Enterprise Manager Cloud Control Upgrade 40

30 Multitenant for Simplified Patching Oracle Multitenant provides a new paradigm for rapid patching Simplifies and speeds up patching process Provides the flexibility to perform selective patching among all pluggable databases a container 41

31 Multitenant for Simplified Patching Patching the Container Database Results in Patching all of its Pluggable Databases 42

32 Running datapatch with Database 12c After OPatch apply, Connect to the DB SQL> Connect / as sysdba SQL> startup SQL> alter pluggable database all open; [only for Multitenant DB] SQL> quit > $ORACLE_HOME/OPatch/datapatch [-verbose] Other options -apply / -rollback <patch_id> -force[-bundle_series]:runs apply/rollback as provided even if it was already done

33 Location of Logfiles DATAPATCH LOG <oracle base>/cfgtoollogs/sqlpatch/<patch id>/<patch uid> And the file name is patchid_[apply/rollback]_<dbname>[_<pdbname>]_<timestamp>.log CATCON LOG - CDB + PDBs /tmp/sqlpatch_catcon_0.log 46

34 Opatch 12.1 Post patch: Check dba_registry_history Check dba_registry_sqlpatch verify status is SUCCESS Note What to do if the status of a datapatch action was not SUCCESS! Database 12c Post Patch SQL Automation (Doc ID ) Oracle Database 12.1 : FAQ on Queryable Patch Inventory (Doc ID ) 48
