WHY did we choose Exadata
HOW did we migrate
and WHAT did we learn after

Our Oracle footprint

Architecture for Oracle Systems

We had
Database hardware for EBS and
OBIEE over three years old
Increased application usage
New business requirements
Already standardised
platforms

Things we were looking for
Cost & Consolidation
Manageability
Scalability & Availability
Future architecture

In the end two choices
vs
Commodity
hardware
upgrade
Exadata

COST
CONSOLIDATION
SCALABILITY
MANAGEABILITY
EXADATA COMMODITY
HARDWARE

Proof of Concept with X3-2 ¼ & OBIEE
No changes
Reduced DOP
No bitmap indexes
SGA 2G
Parallel
13X
36X
62X
62X
36X

With Exadata we get all the evaluated
benefits with similar cost compared
to commodity hardware upgrade
without the need to extend our
license footprint.

September 4th, 2015 we made decision
to migrate our production databases to
Oracle Exadata X5-2 1/8 rack.
December 19th, 2015 we had migrated
our main business applications to
Exadata without major issues.

3 months for e-Business Suite
Review EBS setup
Migration Plan
Focused testing &
background work
KEEP IT SIMPLE!

Remember 3 months? I lied.

Migration before end of 2015
1 Business project Go-Live 1st of January
2016 with performance impact to EBS
2 Decide:
Migration method
Testing focus areas
New operational processes
Exadata setup
3 Implementation partner with
EBS & Exadata knowledge

Migration schedule

Configuration – 2 days
Before: Oracle Exadata Deployment Assistant
Day 1: Physical Installation & Setup
Day 2: Exadata installation & Configuration

Database distribution by Enkitec’s Sizing
and Provisioning tool
Database node 2Database node 1
EBS ERP
HYPERION
EBS ASCP (APS)
OBIEE

Revisited
Oracle RMAN restore configuration
Network setup
Demantra & db_32k_cache_size

Testing
Test all key functionality from each EBS business area
Focus on database specific areas & performance
Interfaces: utl_file & NFS
EBS Batch jobs: Data collections, DB links & JDBC
Exadata specific test cases:
System failures
Infiniband database listener vs normal
Write-through vs Write-back flash cache
I/O Resource Manager profile

Results
100% of test cases
passed without
performance issues
Use write-back cache
Configure infiniband
listener for database
links
EBS specific setup
separate listener
Oracle Home
NFS mounts (dNFS)
No IORM configuration
Database parameters
keep large SGA
parallel settings

Cutover plan
Place concurrent requests ON HOLD in PUPONI 20/11/2015 22:00
Shutdown ERP DB application services on host1, host2, host3, host4
Shutdown ERP DB; startup mount; last archives to rman backup
Shutdown ERP DB database & listener on host X
Confirm services are shutdown and all backups are under /xx/hostX/orabackups including last
archive logs by refreshing /xx mount and verify migration start
00:30
Apply remaining archive logs from backup pieces 20/11/2015 23:30
Validate recovery of ERP DB & startup database
Validate listener is up & running on port 1522
Validate IB listener is up & running
Change database init parameters for ERP DB (based on values on sheet 2)
Validate poststep for PSU/CPU patches are done according to Doc ID 1995261.1
Validate ERP DB is using DirectNFS
Validate huge pages are in use
Gather fixed stats for ERP DB using: exec dbms_stats.gather_fixed_objects_stats;
Modify $ORACLE_HOME/rdbms/admin/externaljob.ora and add following in the end: run_user =
oraexa
run_group = oinstall and follow steps from 6 - Extra tasks B3
00:30
Change Kemp loadbalancer to use port pool 1 and port 8001 20/11/2015 23:30 00:30
01:00
03:00
Restore RMAN level 0 backup & daily level 1 backup
Data validation & shutdown services
Get final archives and finalize restore on Exadata node
Validate recovery & database specific configuration
Run EBS scripts on all nodes (adcfgclone & autoconfig)
Startup EBS services & Gather statistics including fixed stats
Validate services, data, monitoring and backups

Results after cutover
Issue on getting getting listener properly configured
One non-critical report failing with ORA-600
User comments from warehouse: Seems like earlier..
User comments from finance departments:
Unbelievable!!

30 000 concurrent requests daily
Average runtime for requests
during month end closing 65
seconds
After migration 17 seconds

Additional things for migration
Enterprise Manager
Backups
exachk
Default passwords
Communication

Lessons learned after using EBS with
Exadata for one year

Data loads to OBIEE

Before Exadata EBS on Exadata EBS & OBIEE on
Exadata
We now gather full daily set of
