Banner in HCT … Major Banner Upgrade in 2004: • Open VMS DB • Hp-ux DB servers servers • Oracle 9i RAC • Oracle 8i OPS • Banner 5.x • Banner 2.x with • OAS 9i on Linux many customizations servers. • Client Server
Banner in HCT … • In 2005 – Oracle RAC was upgraded to 10g – Upgraded OAS to 10g – Banner was upgraded to 7.x • In 2008: – Upgraded to Banner 8.x – Moved to new hp-ux DB servers – Moved OAS to new RH Linux servers
Banner in HCT … • By 2010: – Increase in • Users • Students • Applications • Demand for more resources. – Started looking into different options
History of Exadata Fastest database server on the planet • Oracle launched Exadata at OpenWorld 2008 in San Francisco. The hardware was manufactured and supported by HP. • April 2009 – Oracle bought Sun Microsystems. • January 2010 - Oracle announced Exadata X2 on Sun based hardware. • August 2011 - Oracle announced Exadata availability with Solaris (in addition to OEL – Oracle Enterprise Linux). • October 1st, 2012 Oracle announced Exadata X3
Key Features of Exadata Database Machine• Exadata Smart Flash Cache – High-performance cache for frequently accessed objects – Frequently accessed data and index blocks are cached. – Control file reads and writes are cached. – File header reads and writes are cached. – DBA can influence caching priorities. • ALTER TABLE customers STORAGE (CELL_FLASH_CACHE KEEP)
Key Features of Exadata Database Machine• Offloading / Smart Scan – cell_offload_processing=TRUE• Predicate Filtering: – Only the requested rows are returned to the database server• Column Filtering: – Only the requested columns are returned to the database• Exadata Storage Index – Storage regions of 1MB • Region Index
Classic Database I/O and SQL Processing1. The client issues a SELECT statement with a predicate to filter a table and return only the rows of interest to the user.2. The database kernel maps this request to the file and extents containing the table.3. The database kernel issues the I/Os to read all the table blocks.4. All the blocks for the table being queried are read into memory.5. SQL processing is conducted against the data blocks searching for the rows that satisfy the predicate.6. The required rows are returned to the client.
Exadata Smart Scan1. The client issues a SELECT statement to return some rows of interest.2. The database kernel determines that the data is stored on Exadata cells so an iDB command representing the SQL command is constructed and sent to the Exadata cells.3. The Exadata Storage Server software scans the data blocks to extract the relevant rows and columns that satisfy the SQL command.4. Exadata cells return to the database instance iDB messages containing the requested rows and columns of data. These results are not block images, so they are not stored in the buffer cache.5. The database kernel consolidates the result sets from across all the Exadata cells.6. The rows are returned to the client.
Test/Development environment for Exadata. • Two servers with OEL were configured with Oracle 11.2 RAC • Configured OFM 126.96.36.199 on a new server. • Cloned Banner DBs and configured. • Banner patches for OFM 11g – Web General: p1-9u56r9_bwg80300 – Web Tailor: b_0410_twb80300 – Student Self-Service: p1-9tz125_bws8040001 – Faculty Self-Service: p1-bc4flv_bwl8040001 – Employee Self-Service: p1-az6zi7_bwp80300 – Finance Self-Service: p1-b1ncjr_bwf80300 – Finance INB: p1-az74ow_fin80400 – p1-iov4k6_gen8040201 – b_0610_twb8030004 • Configured Banner INB and SSB on OFM 11g. • Did rigorous testing.

Banner Test environment with Exadata. • Selected OEL as the OS of Exadata. • Oracle 188.8.131.52.0 • Configured Banner RAC DB in Exadata servers. • Installed OFM 11g on 2 new OEL servers and configured Banner INB and SSB. • Did rigorous testing with Exadata servers. • Tested with other applications and DBs
Exadata in Production. • Migration/Upgrade steps started after office hours on 03-May-2012 (Thursday). 1. Migrated Production DBs to Exadata servers. 2. Configure Banner environment and code tree. 3. Applied Banner Patches 4. Cobol compilers for OEL 5. Configure job submission, sfrpipe, etc. 6. Configured OFM 11g servers for INB and SSB 7. Made configuration changes for Flexible Registration, Touch Net Payment gateway, etc. 8. Scheduled daily jobs on new servers. • 05-May-2012 – Tested by different user groups. • 06-May-2012 – Applications Available to all users.

Performance improvements with Exadata. • Payroll • End of Semester processes – GPA re-calculation – Grade Roll – Schedule Reports – BI Reports • More DBs are being moved to ED
Other Advantages/Improvements • Moved DBs from standalone servers to ED • Reduction in number of DB servers • All DBs are managed at a single place • DBAs should change to DBMA / DMA • Even after moving more DBs, cpu utilization is still below 20% • No complaints related to executing multiple requests of high resource demanding reports/processes.
Other Advantages/Improvements • Twice Patch bundles were applied w/o downtime. • Involvement of Sys Admins is only around 10% • Reduced dependencies on components like SAN • Support from same vendor for all components – ORACLE.
Issues / Challenges faced. • Cross-platform migration – Hp-ux to OEL – Big-endian to Little-endian – Expdp/impdp or transportable tablespace • Difference in Arabic support in OFM from OAS. • User related issues: – Enabled case-sensitive passwords (11g feature)
Plans • Move all DBs • Organize data for performance enhancements. • Utilization of other features.
