Dear Anton and All, How about libaio in the kernel should I disable it? And how to install Oracle 10gR2 without Async I/O? Because according to Metalink, installation Oracle 10gR2 by default Async I/O is TRUE. A. Uncheck module libaio on install SLES? And install Oracle 10gR2, this is make Async I/O disable? B. Installation normal and do : Or still we need to run this : 1) cd to $ORACLE_HOME/rdbms/lib a) make -f ins_rdbms.mk async_off b) make -f ins_rdbms.mk ioracle 2) set 'disk_asynch_io=false' (default value is true) Rgds, cung At 05:38 PM 9/1/2008, you wrote: >Hi, > >yes this should work, > >but make shure you do a -normal- shutdown of oracle first. > >regards, > >Toni > >Am 01.09.2008 um 12:05 schrieb cung: > >>Dear Anton and All, >> >>I am trying to stop the Async I/O and check metalink not found for >>SLES. >>But found for RedHat. >> >>Can I do it for SLES 9 and Oracle 10gR2 >> >>rgds, >>cung >> >> >>https://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=225751.1 >> >>Subject: Asynchronous I/O (aio) on RedHat Advanced Server 2.1 and >>RedHat Enterprise Linux 3 >>Doc ID: Note:225751.1 Type: FAQ >>Last Revision Date: 11-AUG-2008 Status: PUBLISHED >> >>Q: 7.How can I disable the Asynchronous I/O? >> >> >>A: If asynchronous I/O needs to be disabled for some reason, please >>execute the following steps : >> >>1) cd to $ORACLE_HOME/rdbms/lib >> >>a) make -f ins_rdbms.mk async_off >> >>b) make -f ins_rdbms.mk ioracle >> >> >>2) set 'disk_asynch_io=false' (default value is true) >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >> >>At 04:00 PM 9/1/2008, you wrote: >>>Hi cung, >>> >>>SLES9 has severe problems with async io. >>>I believe it startet with SP2 und maybe it's still not fixed in SP4. >>> >>>Switching off async/io is huge speed decrease. >>> >>>I believe there is a SP4 for SLES9. >>> >>>You might wanto to try this first. >>> >>>Onother option my be to swith to SLES10 which has no async/io >>>problems. >>> >>>Good luck, >>> >>>Toni >>> >>>-- >>> >>>+-----------------------------------------------------------------+ >>>| Anton Dischner, Unix admin, DBA Phone: +49 89 70953202| >>>| Institut fuer Klinische Chemie Fax : +49 89 70958888| >>>| Klinikum Grosshadern Home : +49 89 69708766| >>>| Ludwig Maximilians Universitaet Muenchen Mobil: +49 172 8388880| >>>| 81366 Muenchen Germany | >>>| Marchioninistr. 15 Anton.Dischner"at"med.uni-muenchen.de | >>>+-----------------------------------------------------------------+ >>> >>_______________________________________________ >>suse-oracle mailing list >>[email protected] >>http://listx.novell.com/mailman/listinfo/suse-oracle > >-- >+-----------------------------------------------------------------+ >| Anton Dischner, Unix admin, DBA Phone: +49 89 70953202| >| Institut fuer Klinische Chemie Fax : +49 89 70958888| >| Klinikum Grosshadern Home : +49 89 69708766| >| Ludwig Maximilians Universitaet Muenchen Mobil: +49 172 8388880| >| 81366 Muenchen Germany | >| Marchioninistr. 15 Anton.Dischner"at"med.uni-muenchen.de | >+-----------------------------------------------------------------+ > > _______________________________________________ suse-oracle mailing list [email protected] http://listx.novell.com/mailman/listinfo/suse-oracle
