|---|---|
| Article Number | 16634 |
| Environment | Windows Server 2008 Orbix 6.3.4 |
| Question/Problem Description | Is the use of "Enable write caching on the disk" setting recommended with Orbix 6.3? Which policies settings are recommended for a physical disk drive? |
| Clarifying Information | |
| Error Message | |
| Defect/Enhancement Number | |
| Cause | "Optimize for performance" generally enables write caching for the disk, but Berkeley DB flushes writes when it needs to, thus effectively overriding that policy, for those writes.
"Enable write caching on the disk" literally enables caching of write operations in the cache inside the physical drive, the one between the drive’s controller and the physical stable media. |
| Resolution | The use of "Enable write caching on the disk" and "Enable advanced performance" is not recommended for the Berkeley DB used with Orbix. |
| Workaround | |
| Notes | Please also review the following documentation of the Berkeley DB:
