Professional Experience

Walt Disney World - Orlando, FL

RCG Global Services, Technical Consultant (Aug 2012 - Nov 2012)

Tune Business Objects Reports SQL code that (after being ported from DB2 to Oracle) failed to meet established SLAs. Using the Oracle Server DB diagnostic utilities as well as having access to a fully loaded performance test environment, tuned reports to meet or exceeded DB2 timings.

Benchmarked new Release 2.4 SALES application. Specifically tuned "PIN Load" process by trouble-shooting database gc buffer busy and log file sync wait events. Decreased and eliminated wait times through recommending application developers decrease number of COMMITs in their application code as well as fine tune index definitions on the application's interim staging table. Transactions/SEC (TPS)increased from ~80 to ~130.

Facilitated communication between the Application Development and DBA teams.

Office Depot - Boca Raton, FL

SDI International, Corp., Lead Oracle Database Administrator (Jan 2012 - Aug 2012)

Troubleshoot, diagnose, and repair (tune) production Oracle 11i ERP (including all third-party integrations points) application and database server performance problems by: 1.) identifying changed SQL execution plans and implementing SQL baselines, 2.) optimizing 11gR2 SQL execution plans through re-writing application SQL and PL/SQL code, adding indexes, and/or hints, 3.) archiving and purging data, and 4.) reorganizing table, index, partitions, and tablespaces. Database server configuration included a seven-node, 11gR2 RAC cluster, utilizing Oracle Partitioning.

Worked as part of the DBA project team to physically decrease production OLTP database size from >30TB to ~15TB through the use of SEGMENT on-line redefinition (DBMS_REDEFINITION) as well as DATAPUMP (expdp/impdp) to/from ASM and/or over DB Links.

Performed the migration and upgrade of client's Informatica Oracle Applications historical database server from 10gR2 Single Instance to 11gR2 RAC.

Reconfigured, re-implemented, and re-deployed Informatica Data Archive and Purge projects moving ~2 billion rows of Oracle Applications 11.5.10 Sales Order production data off tier-one storage and onto tier-two storage (~750GB of data). Tune archive/purge jobs by multi-threading JDBC Thin Client connections and tuning Oracle Parallel DML (INSERTs/DELETEs).

Documented and transitioned the Sales Order archive/purge procedures and provided POC to the client for the configuration, implementation, and deployment of Informatica Data Archive and Purge projects in an effort to move 11.5.10 GL Journals-Actuals data. Again, the estimate provided from the POC was to move ~2 billion rows off tier-one storage to tier-two (~750GB of data).

Troubleshoot, diagnose, and repair performance problems of Informatica Seamless Data Access Oracle Server views that combine OLTP and Historical Sales Order and GL data so that historical data remains available to users as needed.
