Configuration topics for Oracle database on HP-UX with ASA r2 ONTAP.

Note

HP-UX is supported with NetApp ASA r2 for hosting Oracle databases, provided:

  • ONTAP version is 9.16.x or later.

  • Use SAN protocols (FC/iSCSI/NVMe). NAS is not supported on ASA r2.

  • Apply HP-UX-specific mount and I/O tuning best practices.

HP-UX VxFS mount options

Use the following mount options for file systems hosting Oracle binaries:

delaylog,nodatainlog

Use the following mount options for file systems containing datafiles, redo logs, archive logs, and control files in which the version of HP-UX does not support concurrent I/O:

nodatainlog,mincache=direct,convosync=direct

When concurrent I/O is supported (VxFS 5.0.1 and later, or with the ServiceGuard Storage Management Suite), use these mount options for file systems containing datafiles, redo logs, archive logs, and control files:

delaylog,cio
Note The parameter db_file_multiblock_read_count is especially critical in VxFS environments. Oracle recommends that this parameter remain unset in Oracle 10g R1 and later unless specifically directed otherwise. The default with an Oracle 8KB block size is 128. If the value of this parameter is forced to 16 or less, remove the convosync=direct mount option because it can damage sequential I/O performance. This step damages other aspects of performance and should only be taken if the value of db_file_multiblock_read_count must be changed from the default value.
