oracle management repository 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
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.

preparation
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)
preparation1
Preparation
  • O/S (Kernel parameters)
  • O/S Patches (install all listed)

agent deployment
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)

summary
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
