With 18 years of IT experience including: Oracle database administration, Unix system administration,Manufacturing mentoring, instructing, patching, migrating, upgrading, technical team lead,Telecom authored and administered a wiki artifact for DBAs.Professional Professional ExperienceSpecializationOracle RDBMS, HA 2009-2012 Research In MotionArchitect, RDBMS DR/UnixSystems Manufacturing: Senior DBA: Responsible for administering 6 RAC hubs and Exadata machines globally distributed across Singapore, England and North America (NA).Technical SkillsExadata • Migrated each of the six RAC hubs from Linux x86 to HP-UX ItaniumOracle architecture including Oracle Golden Gate (OGG) instantiations. During testingOracle Golden Gate phase, conducted a 2x and 3x stress test using load runner. Network WAASUnix Admin HP-UX switches tuned for this load to sustain rate of change to its DR sites.Unix shell scriptingOracle Data Guard • Managed Exadata compute nodes and cell nodes and frequently dealt withRAC disk replacement failures completely transparent to end users/applications viaOracle Transparent the ASR (Automatic Service Request) set up.Gateway • Implemented a 3 prong strategy standard portable backup script across allOEM 12c, OEM 11g hubs to minimize recovery times that included a full/archive/image backups andRMAN Data Guard as a last resort.DW Implementation & • Led the team through a double disk fault failure causing impacts to two NAAdministration hubs and their standbys. Readily deployed the image copy switch recoveryTkprof strategy which team members were not aware of its possibilities. BackupAwk & sed strategy minimized manufacturing outage loss.NetApp Storage • Initiated much needed alerting scripts such as: log clearing, file system flooding, OGG manager abend status’, listener/alert log cleanup, standbyCertifications database log shipment/apply delays, etc.Oracle11g ,10g, 9i, 8i ,8 • Introduced the MOP (method of procedure) concept for productionTOGAF 8 deployments, also as there was no documentation, exposed the team to build books, and further excited the advent of a team WIKI containing all sorts of DBA artifacts. • Aided in the implementation of a 6 way OGG replication for the use of sharing global data between manufacturing sites across the globe. • Proposed a new architecture of OGG to a hub and spoke methodology to simplify the infrastructure. • Consolidated OGG extract/replicat parameters for ease of use and administration. • Implemented an integration script to pull data from three chip vendor’s(QC,TI,Marvell) ftp site and load its data in GMS (Manufacturing
    • Tony Bruzzese 216 Kingshill Rd. tony.bruzzese@gmail.com Richmond Hill, Ontario L4E 4V4  289-809-0463 database). This was the basis of the BSIS (Blackberry Security Infrastructure Service) devices that led the manufacturing of a secure/authentic BB. • Frequently sought out to troubleshoot latency issues in programs such as Label Print and ASY (Assembly) with the use of 10046 trace data. • Asked to plan, develop, document, test, and deploy a DR switchover for each of the 6 hubs for duration of one week before switching back. This led to the solidification of the DR databases and network infrastructure coupled with its capability to run manufacturing on its DR servers. • Exposed a network latency issue between Singapore and England through the use of a home grown script redirecting the focus to England rather than Singapore as it was believed to be the issue. The root cause was an IOS version known for dropping data packets and upgrading the IOS solved the problem. • Successfully deployed 10g to 11g RAC upgrade using scan listeners and RIM’s usual 2x and 3x performance stress tests. • Coached the team on the use of Oracle active duplication to refresh UAT environments on a monthly basis and one of many artifacts documented in the team WIKI. • Migrated RIM’s 60TB archive database from expensive HP’s XP24 disk arrays to NetApp filers to reduce cost of ownership.1997 – 2009 CGI Architecture & TechnologyClient: Bell ExpressVu; iTV UpgradeSenior Technical Consultant: Two-phase upgrade, e.g. from 9.2.0.1 to 9.2.0.8 and 9.2.0.8 to 10.2.0.3. The two-phaseapproach was so that we could meet 10g ability to downgrade to the minimum 9i release, e.g. 9.2.0.4. • Managed team of 4 overseeing their deliverables.Client: Bell Canada; OrderMax Oracle Upgrade • Oracle upgrade of a Data Guard environment and a single instance database. • Introduced real-time apply for quicker recovery of the physical standby database, including max connections option to the LGWR process. • Discovered real-time apply bug and through an SR, a back-port fix was provided for AIX. • Conducted switch-over testing and found out that additional bugs exist in 10.2.0.3 and remediate it through a Data Guard patch bundle addressing many switch-over issues in the database. • Also, added April CPU2008.Client: Bell Canada; bell.ca Database upgradeSenior Technical Consultant: bell.ca hosts all of Bell Canada’s content information. It is the entry points of allresidential and commercial consumers hence its high visibility to external and potential customers. • Very sensitive upgrade and scrutiny from Bell VPs since this is the second attempt within the last year to upgrade bell.ca from 9i to 10g. • Bell.ca database configuration includes Data Guard. • Successfully developed, tested, and executed upgrade process including the introduction of real-time apply whereby a known issues was discovered with real-time apply and Oracle subsequently provided a back-port for HP-UX parisc architecture. • Customer testimonials were overwhelmingly a great success in that database performance was even better in the upgraded release. • Learned from the previous team’s attempt and cautiously applied workarounds from that experience.
    • Tony Bruzzese 216 Kingshill Rd. tony.bruzzese@gmail.com Richmond Hill, Ontario L4E 4V4  289-809-0463 • Conducted thorough research on 10.2.0.3 known issues and workaround and applied appropriate one-off patches to mitigate certain common vulnerabilities in the database including Critical Patch Update.Client: Bell Canada; Max+ Database upgradeSenior Technical Consultant: The project was to upgrade two databases from 8i to 9.2.0.8 whereby one of thedatabases has a physical standby database. • CGI project manager sought me out to aid in the development through the execution of the upgrade including testing of the top 10 SQL queries in the upgraded database. • Methodology chosen for the upgrade was to employ the exp/imp utility and the reasons where twofold: o Re-create tablespaces to include ASSM feature. o Natural database reorganization – database size shrank from 40GB to 12GB • Successfully presented Oracle upgrade strategy & convinced Bell VP, whom was very weary of the upgrade due to two highly visible upgrade failures in the near past that CGI would conduct a successful upgrade through proper test cycles from SIT, UAT, and a two cycle performance stress tests.Client: Bell Canada; Tivoli Data Protector Centralization to IBMSenior Technical Consultant: Bell mandate to centralize administration of 13 Oracle RMAN backups via TDP from CGI-DBA’s to IBM DBA’s as part of the on going tape storage cost reduction initiative to Bell by adopting the same AIstandard backup policy. • Coordinated CGI effort to identify and document Oracle database instances that currently use TDP as the media management layer. • Granted appropriate privileges to IBM to the Oracle databases that would give them the ability to manage and administer the Oracle database backups while integrating the target databases to IBM’s RMAN catalogue. • Ensured that CGI DBA’s have not compromised database security while allowing IBM to possess SYSDBA access via a non-Oracle group account.Client: Bell ExpressVu; Project OPS Re-designSenior Technical Consultant: Introduction, expansion, and de-risking of BEV application environments. Over 130applications sharing the same Oracle back end of approximately 1 TB of data with numerous schemas of the variousapplications. The project strategy was to de-couple schemas from the current database environment to a set of newdatabases in order to decrease the load on the current OPS production database, improve performance andavailability, and mitigate business outages by leveraging AI infrastructure hosting services. • HA architecture will consist of Oracle RAC, Veritas Storage Foundation for Oracle RAC, and a physical DataGuard for data/environmental protection. • A phased approach in the database migration will minimize the impact on BEV business. o The first phase of the project consists of the analysis and migration strategy definition. o The second phase includes the construction and coordination of necessary environments, migration of critical on-line schemas and associated data migrations to new Oracle instances. • Heavy uses of db-links were deployed during the segregation of schemas due to the inter-relationships of the applications. Oracle Streams was another option discussed rather than db-links, but we felt that Oracle streams would be better deployed on Oracle 10g rather than 9i where Streams was first introduced. Oracle concurred.
