About using Veritas Access with Oracle Direct NFS
Veritas Access lets you create and manage storage for Oracle database clients. Oracle hosts access the storage using Oracle Direct NFS (DNFS).
Oracle Direct NFS is an optimized NFS (Network File System) client that provides faster access to NFS storage that is located on NAS storage devices. The Oracle Database Direct NFS client integrates the NFS client functionality directly in the Oracle software. Through this integration, the I/O path between Oracle and the NFS server is optimized, providing significantly better performance. In addition, the Oracle Direct NFS client simplifies and, in many cases, automates the performance optimization of the NFS client configuration for database workloads.
The Oracle Direct NFS client outperforms traditional NFS clients, and is easy to configure. The Oracle Direct NFS client provides a standard NFS client implementation across all hardware and operating system platforms.
Veritas Access creates different storage pools for different Oracle object types. Veritas Access has the following storage pools as described in Table: Veritas Access storage pools for Oracle object types.
Table: Veritas Access storage pools for Oracle object types
Pool Name | Database Object Type | Function |
---|---|---|
ora_data_pool | Oracle TABLE data files | Stores TABLE data of data files. This database object type uses striped volumes over four LUNs. The stripe size is 256K. |
ora_index_pool | Oracle INDEX files | Stores INDEX data. |
ora_temp_pool | Temporary files | Stores temporary files. The storage administrator should make sure the LUNs are from the fastest tier. Temporary files are used for sort, merge, or join queries. |
ora_archive_pool | Archive logs | Stores archive logs. This database object type is a concatenated volume. Tier 2 LUNs can be used for this storage pool. |
ora_txnlog_pool | REDO txnlog files | Stores REDO transaction logs. It is recommended to assign the fastest storage LUNs to this storage pool. |
