Best practices for improving Oracle database performance
Oracle database performance depends on I/O bandwidth and latency.
The Oracle database has the following object types:
DATA
INDEX
TXNLOG
ARCHLOG
TEMPFILES
See About using Veritas Access with Oracle Direct NFS.
The Oracle database transaction rate depends heavily on TXNLOG write latency.
Table: Best practices for improving Oracle database performance
Item | Action |
---|---|
DATA and INDEX files | Separate DATA and INDEX files into separate disk pools with a minimum of four LUNs. |
REDOLOG files | Configure REDOLOG files in a separate file system (NFS share). The underlying storage LUNs should not be shared with other volumes or file systems. |
TEMPFILES | For data warehouse applications, keep TEMPFILES in separate pools with a minimum of four LUNs. |
TXNLOG files | Place TXNLOG files in a separate disk pool with dedicated fast LUNs. |
NFS daemon threads | To get better performance, increase NFS daemon threads to 128 or more. If the network permits, you may want to enable jumbo frames. |
Veritas Access database-specific file systems | Access Veritas Access database-specific file systems from the Oracle host using dedicated virtual IPs. Do not use the same virtual IP for other applications. |
Veritas Access file systems | Always use Oracle recommended mount options to mount Veritas Access file systems on the Oracle host. This mount option depends on the Oracle database version. See the Veritas Access Installation Guide for the supported Oracle database versions. See the Oracle documentation for the recommended mount options. |
