Oracle Tips

RAM and the Oracle Server


The purpose of server optimization for the Oracle database is to manage the RAM and CPU resources of the machine and ensure that expensive RAM is not under-utilized. The techniques used to optimize Oracle database performance on large UNIX platforms are similar to those used for a MS-Windows system.

Most Oracle consultants see shops waste millions of dollars worth of RAM. The RAM is under-allocated because the DBA is unaware of how to accurately analyze the RAM demands of the database. RAM is very expensive on larger servers and depreciates regardless of use.

The knowledgeable DBA will know how to accurately predict the maximum RAM demands for the database and will allocate RAM fully, holding in reserve only enough to accommodate user connection spikes. Let’s review disk swapping and see how this is accomplished.
