| Direct and Asynchronous I/O - Take advantage of the performance advantages associated with Direct and Asynchronous I/O. |
Christoph said... With version 10.1 you need to relink on LINUX your executables.See http://www.nextre.it/oracledocs/asincio.html |
Roger said... Hi Tim,Unfortunately the options are not quite correct. ASYNCH - Enabled synchronous I/O where possible. DIRECTIO- Enabled direct I/O where possible. SETALL- Enabled both direct I/O and synchronous I/O where possible. ASYNCH - Disabled both direct I/O and synchronous I/O. Synchronous should be replaced with asynchronous and ASYNCH is listed twice the last option should read NONE. It should read something like this. ASYNCH - Enabled asynchronous I/O where possible. DIRECTIO- Enabled direct I/O where possible. SETALL- Enabled both direct I/O and asynchronous I/O where possible. NONE - Disabled both direct I/O and asynchronous I/O. Cheers, Roger. |
Tim... said... Hi.Whoops. Bad cut and paste. :( Thanks for the heads-up. I've corrected the mistake. :) Cheers Tim... |
Roger said... Hi Tim,You are having a bad day ;-) It still reads synchronous rather than asynchronous in the option descriptions. Cheers, Roger. |
Tim... said... Hi.I've just corrected it. Thanks for being so patient. I'm at OpenWorld and the jet lag is killing me. :) Cheers Tim... |
Cliff said... The text still appears to be incorrect.It should be as Roger points out ASYNCH - Enabled asynchronous I/O where possible. DIRECTIO- Enabled direct I/O where possible. SETALL- Enabled both direct I/O and asynchronous I/O where possible. NONE - Disabled both direct I/O and asynchronous |
Tim... said... Hi.3rd time lucky... I hope. I think I've got them all now. :) Cheers Tim... |
Wayne T Smith said... Setting DIRECTIO is not without risk. I have one older 64-bit, non-LVM, Linux system where this caused the DB to not start. One of the control files was corrupted. References: 132565.1, 360287.1 and the DB Admin Guide. cheers, wayne |
