Implementing OEM for the First Time Gary Gelder Sr. Database Administrator Mirant Corporation Gary.Gelder@mirant.com
Agenda • Pieces of the puzzle • Preparation • Installation • Agent deployment • Monitoring • Q & A
Pieces of the puzzle Admin Browsers OMS OMR Software OMA Hardware Targets Free
Enterprise Manager Architecture Application Server Console (Browser) EM Agent Oracle Database HTTP/S Computer Host EM Agent JDBC Oracle 10g Management Service Management Repository (Database) Oracle 9i EM Agent Oracle 10g Managed Targets OMA OMS OMR
Oracle Management Repository (OMR) • Oracle 10g database • Includes objects belonging to SYSMAN • Can be installed in a pre-existing database • Can be configured to contain other management data • Application server infrastructure database • RMAN Catalog
Oracle Management Agent (OMA) • Must be installed on each managed host • Must be in its own ORACLE_HOME • Communicates with OMS via HTTP or HTTPS • Installed from OEM (pushed down to the host) or can be installed locally.
Enterprise Manager 10g Product (OMS) • Enterprise Manager 10g Grid Control • Oracle’s grid-ready framework, allowing IT professionals to manage the entire Oracle eco-system through one integrated management console. • Enterprise Manager 10g Database Control • Database Control is the front-end tool for managing a single instance of the 10g database or single cluster instance. • Enterprise Manager 10g Application Server Control • Oracle’s application server management interface built directly into the Oracle 10g application server infrastructure

Managed Targets • Databases • Listeners • Application servers • Collaboration Suite • Most O/S systems that are certified to run Oracle Products • Third Party products and applications • API available that enables you to create custom targets not provided by Oracle
Accessing the Grid Control Console • Netscape Navigator 4.78, 4.79, 7.01, or 7.1.0 • Mozilla 1.3.1 • Microsoft IE 5.5 (SP1) or 6.0 (SP2) • Microsoft Pocket IE 2.0 for HTTP or 3.0 for HTTPS
Administrators • Default Administrators • DBA • Production and Non-Production • Others
Hardware • General guidelines • Small enterprise • Memory 1-2 GB • Disk space 2.5 GB • Large enterprise • Memory 2-4 GB • Disk space 5 mb for each managed target
Software • Any supported operating system • Sun Solaris • HPUX • HP Tru64 • Linux • IBM AIX • Microsoft Windows
Preparation • Allow plenty of time • Read the Quick Installation Guide (For those of us that don’t like to read installation manuals) • Review Installation guide • Determine Configuration (1 or 2 servers, Oracle recommends separate) • Hardware requirements • Disk space (It will stop the install if not available, including /tmp space)
Preparation • O/S (Kernel parameters) • O/S Patches (install all listed) • ssh configuration • Password definitions • Metalink access • Mail Server Information
Installation Option B: single servers Option A: 2 separate servers Management Repository (Database) Management Service Management Repository (Database) Management Service Server A Server B Server C
Default Settings • Administrators • SYSMAN • SYS • SYSTEM • Preferences • Rules
Agent Deployment • Installs agent at the host server • Installs Oracle Home for agent • Could take some time to deploy. • Gather Stats on host after install (may cause some performance issues first time through)
Management Pack Definition • Enable/Disable Management Package • All are enabled by default • Alter Management Pack access according to license agreement
Monitoring • Rules • Subscribing • Paging and Emails • Production and Non-Production
Summary • We Have: • Reviewed components of OEM • Looked at some of the configuration items • Determined that there are a lot of pieces to OEM • It takes time to utilize OEM • Put in a timeline • Practice on sandbox • Installed on prod server • Setup about 1 week (with other duties) • Will be expanding use this year Hopefully this will help with your implementation of OEM
