PeopleSoft Database Consolidation Questions and Answers

About the University of Minnesota
Founded:1851 Five Campus Locations Enrollment: 69,221 (52,557 on Twin Cities campus) Alumni: ~400,000 Economic Impact: $8.6 billion into MN annually

Size of the Business
4
The Upgrade Enterprise System Upgrade Program (ESUP)
Updating PeopleSoft systems CS from 8.9 to 9.0 HR from 8.9 to 9.2 Includes a split from CS Finance from 8.9 to 9.2 PeopleTools from to Implementing PeopleSoft Interaction Hub (Portal) and Secure Enterprise Search
5
System Architecture Infrastructure in a box Sun ZFS storage
InfiniBand Gateway switches Management tools Oracle Traffic Director Running PeopleSoft Applications 5 Applications 11 Environments 110 VMs 500 Domains
6
Exalogic and PeopleSoft
OVM Templates configured Dynamic DNS updates PeopleSoft domains deployed and managed via Python scripts NFSv4 shared mounts for PeopleSoft file systems Pure SDP protocol from web servers to Exadata
7
Benefits of “Exa” Architecture
Full redundancy of Exalogic/Exadata Production DR on 2nd Exalogic rack InfiniBand interconnect between Exadata and Exalogic Streamlined Administration All components supported by Oracle

University of Minnesota: DBaaS
Deployed in April 2011 Standardized infrastructure: Solaris → Linux Database 9.x, 10.x, 11.1 → 11.2 Single DR, backup, and HA strategies Centralized administration of databases Database “hotel” concept Exadata X2-2
9
DBaaS: Hotel Concept Candidate apps are typically under 50GB
Currently ~150 hotel schemas Two hotel instance stacks (dev/tst/qa/prd/DR) for single- and multi-byte charsets Meets needs of 95% of database consumers Managed backups, security, DR, and compliance for all
10
DBaaS: Before and After
40+ database servers 225+ instances 8 FTEs 45 backup scripts 8 db servers (Exadata) ~30 instances 3 FTEs 12 backup scripts Two hotel stacks 35 customers ~150 hosted schemas $200,000/year savings
11
PeopleSoft Consolidation: Why
Proven success with database “hotel” Provide more applications using fewer databases Positions us for Database 12c multi-tenant Support from Oracle & PeopleSoft Simplified administration, monitoring, and refreshes
12
PeopleSoft Support Model
One team supports the PeopleSoft Architecture
13
PeopleSoft Database Landscape
Current databases: 24 2 apps: CS/HR and Finance 14 Environments Planned databases: 18 5 apps: CS, HR, Finance, Portal, Secure Enterprise Search 11 Environments
14
PeopleSoft Consolidation: Details
Each application has a schema Dedicated tablespace Dedicated temp tablespace Quota on undo 4-node RAC database Each application has affinity to two “primary” nodes and a designated “failover” node
15
Consolidation Benefits
Easier administration of application stacks Better resource usage on Exadata Cross-application functionality streamlined Inter-schema table references instead of database links Complementary business cycles E.g., when CS is busy, HR and Finance are in slow phase
16
Consolidation Benefits
Reporting snapshots are simplified One daily snapshot instead of two Data at same point in time across all applications Disaster recovery is easier All applications would be recovered to the same point in time Security is addressed across the board
17
Consolidation Risks Potential for resource contention
If the database goes down, all applications are also down Oracle patch requirements may change in time
18
What’s Next ESUP project go-live is February 2015
Oracle Enterprise Manager 12c monitoring and administration Database, Exadata, and Exalogic PeopleSoft plug-in Testing in the consolidated database model has gone well
