Agenda
• Oracle Database Appliance as the DB platform for e-Business Suite
• How Pythian migrated e-Business Suite DB to ODA
Oracle Database Appliance?
- Engineered by Oracle for Oracle - Simple deployment / pre-configured - Reliable / pre-tested - Highly Available - Good performance - Easy management - One vendor - Pay as you grow licensing - 50K$ (60K$ for X3-2)
Inside the box…
• 2 DB servers, each configured with: ODA ODA X3-2
2* Xeon X5675 6-core CPUs 2* Xeon E5-2690 8-core CPUs 96Gb Memory 256Gb Memory
500Gb - mirrored storage for OS / SW 600Gb - mirrored storage for OS / SW 1x 10 GbE and 3x 1 GbE 4x 10 GbE
Inside the box…
• Shared storage ODA ODA X3-2
+DATA +RECO
20x 600Gb 3.5inch 15Krpm SAS 4TB ASM High redundancy
6TB ASM Normal Redundancy (v2.4)
20x 900Gb 2.5-inch 10Krpm SAS-2 6TB ASM High Redundancy
9TB ASM Normal Redundancy
+REDO 4x 73Gb SSD drives for +REDO 90Gb ASM High Redundancy
4x 200Gb SSD drives for +REDO 260Gb ASM High Redundancy
Non-expandable *Optional 2nd storage shelf doubles the capacity
Limitations • Limitations by design
* No Scaling Up * No Scaling Out * possibility of using NFS Storage (why would you do that)
* Storage Expansion is available for X3-2
• Supportability limitations * Use oakcli (OracleApplianceKitClient) for any patching * Additional software not allowed (except agents)
* Virtualization support option (v2.5 / X3-2) can help!
* One-off patches are not supported [ID 1399055.1]
ODA Application Kit Releases • Every ~3 months
* Bundle patch * Bare Metal OS ISO Images (Patch 12999313)
• Major new features (ODA v1) * v2.1 – (Oct 2011) – Single 11.2.0.2 OH * v2.2 – Upgrade to 11.2.0.3 * v2.3 – Support for multiple OHs 11.2.0.[23] * v2.4 – Normal redundancy for +DATA and +RECO * v2.5 – (Feb 2013) Oracle VM /X3-2 starts here/
• Think about the upgrade strategies!
Certification and Support • How certification works?
* Oracle certifies HW platforms and Operational Systems * Oracle does not certify specific hardware configurations
for software products
* ODA is a cluster of two x86-64 OEL 5 servers * 11gR2 is certified on Linux x86-64 with OEL5 * eBS is certified with 11gR2
eBS DB is certified on ODA 11gR2 and R12.1 are in premier support
Monitoring and Management • How to operate ODA in your IT infrastructure?
* [ID 1415773.1] 3rd party agents are supported! * Agents “manage, monitor, backup, replicate,
authenticate, or otherwise act on the database, the server, or the environment”
* NetBackup, Networker, etc.
• Monitoring is important! * HW: Use Auto Service Request (ASR)
* Monitors HW Faults * Collects information and creates SRs automatically
* SW: Use your favorite monitoring framework
How Pythian Migrated R12.1 e-Business Suite DB to ODA v2.2
Scope of the project
• The Source - R12.1.3, 10g RAC, old Hardware
• The Target - Migrate the DB to ODA - Upgrade the DB from 10.2.0.5 to 11.2.0.3 - Consolidate 4 DBs into one ODA - Install 900+ e-Business Suite patches
Important MOS notes
- Interoperability Notes EBS 12.0 and 12.1 with Database 11gR2 [ID 1058763.1]
- Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 12 [ID 823587.1]
eBS DB tier requirements
• Requirements colliding with ODA supportability * Install products from the 11g Examples CD * 8 one-off patches for 11.2.0.3 * Requires dedicated oracle listener * Customized TNS_ADMIN and ORA_NLS10 variables * No specific requirements for the grid home
Default ODA Oracle Home is not suitable
How we did it…
• /u01/cst for the customized software • Separate Oracle Inventory
* /u01/cst/oraInventory * Allows keeping the default inventory clean
• Separate Oracle Home * /u01/cst/{DB_NAME}/product/11.2.0.3 * Cloned it from the default OH * Installed the Products from Examples CD * Installed required one-off patches
Challenge: the DB upgrade • Why it was not simple?
* Source DB is 10.2.0.5 on old/slow hardware * compatible.rdbms = 11.2.0.2 for all ASM diskgroups on
ODA
• What options did we review? * In-place upgrade + migration to ODA = SLOW * Install 10gR2 on ODA and create standby = IMPOSSIBLE
because of Database Compatibility of ASM diskgroups * Rebuild the ASM diskgroups with lower compatible.rdbms
setting = TOO INTRUSIVE
Solution: the DB upgrade
- FAQ about Restoring Or Duplicating Between Different Versions And Platforms [ID 369644.1]
* Restore 10.2 backup using 11.2 software * Apply archived logs periodically * alter database open resetlogs upgrade * Continue the upgrade process
The DB upgrade completed in 1.5 hours
Initialization parameters
• Mandatory settings for eBS in [ID 396009.1] • From a DB created by “oakcli create database” * _disable_interface_checking=TRUE * _ENABLE_NUMA_SUPPORT=FALSE * _FILE_SIZE_INCREASE_INCREMENT=2143289344 * _gc_policy_time=0 * _gc_undo_affinity=FALSE * _KGL_CLUSTER_LOCK_READ_MOSTLY=TRUE * _kill_diagnostics_timeout=140 * _lm_rcvr_hang_allow_time=140 * db_block_checking='FULL'
* db_block_checksum='FULL' * db_lost_write_protect='TYPICAL' * filesystemio_options='setall' * parallel_adaptive_multi_user=FALSE * parallel_execution_message_size=16384 * parallel_min_servers=0 * parallel_threads_per_cpu=2 * use_large_pages='ONLY' * compatible=11.2.0.3
Separate listener for eBS
• Don’t use port pool 0 for eBS * The ODA default listener runs on 1521 * Avoid port conflicts!
• Create the listener * srvctl add listener -l LISTENER_EBSDB -o
$ORACLE_HOME –p 1522 * srvctl setenv listener -l LISTENER_EBSDB -T
TNS_ADMIN=$ORACLE_HOME/network/admin
Clusterware DB resource
- srvctl add database -d EBSDB -o /u01/cst/EBSDB/product/11.2.0.3 -p +DATA/EBSDB/PARAMETERFILE/spfile.704.792145311 -a "DATA,RECO,REDO" -n EBSDB
- srvctl setenv database -d EBSDB -t "TNS_ADMIN=$ORACLE_HOME/network/admin,ORA_NLS10=$ORACLE_HOME/nls/data/9idata”
- srvctl add instance -d EBSDB -i EBSDB1 -n oda01a-net1 - srvctl add instance -d EBSDB -i EBSDB2 -n oda01b-net1
Net Services configuration
• Cluster services use default TNS_ADMIN * $ORACLE_HOME/network/admin * It has to be the same on both nodes
• AutoConfig TNS_ADMIN differs on each node * $ORACLE_HOME/network/admin/$CONTEXT_NAME
• Set the IFILE settings: * echo "IFILE=${ORACLE_HOME}/network/admin/$
{CONTEXT_NAME}/sqlnet.ora" > $ORACLE_HOME/sqlnet.ora * Repeat the same steps for tnsnames.ora and listener.ora
Impact on ODA’s patching • Minimal impact
* Default OH and inventory are not customized.
• eBS configuration points visible to oakcli * /etc/oraInst.loc – switch between inventories manually * /etc/oratab
* Patch ODA’s components one by one [ID 1458353.1]: use --infra, --grid, --database options of “oakcli update”
* Avoid running automated update of all DBs on ODA * Clusterware resources for eBS DB
* Should not cause issues * Easy to remove and recreate if needed
* Data on ASM diskgroups
Impact on eBS DB patching • No restrictions to apply one-off patches on the
eBS DB Oracle Home • ODA’s Patch Bundle is needed for - Patchsets and PSUs to eBS database
* Can’t be installed separately, dependencies on grid OH * Grid OH has to be patched using ODA Patch Bundles
- Security Updates to eBS database * PSU patches include security fixes * eBS database has a PSU installed (11.2.0.3.2) * ID 854428.1 – If a PSU was installed, future security fixes have to
be applied using subsequent PSUs
Future Perspective
• Transformation from ODA to *ODAA * v2.5 – Oracle VM on ODA * *ODAA = Oracle Database and Application Appliance J * Oracle eBS is certified with Oracle VM 3.1.1 [465915.1]
• ODA X3-2 * It’s unlikely ODA v1 will ever support HW upgrades * Bigger! - more HDD/RAM/CPU * Better? – (careful with IO)
Conclusions
- ODA is great for small/medium sized DBs - No official support for e-Business Suite DBs yet - Low-impact customization needed to run eBS DB - 5 months in production – 0 crashes
