Oracle RAC Installation and Tuning

 

DSI is experienced in RAC installation and administration on since version 9i. We help identify the improvements that RAC can provide your organization, such as SCAN setup for client communications in 11gR2 RAC.

We advise you on RAC upgrades and we also set up refresh processes from RAC to single mode non production environment and to RAC non production environments.

If you’ve extended your RAC cluster on a set of new nodes, you already know how painful it can be to have to go through your list of clients and make sure their SQL*Net configuration is up to date. We can resolve this problem using Single Client Access Name (SCAN).

Analyzing performance issues in RAC involves several key areas:

  • Normal database tuning and monitoring
  • Monitoring RAC cluster interconnect performance
  • Monitoring workloads
  • Monitoring RAC-specific contention

We monitor Undesirable Global Cache Statistics like global cache blocks corrupt. This statistic shows if any blocks were corrupted during transfers. If high values are returned for this statistic, there is probably an IPC, network, or hardware issue that needs to be reviewed.
