First:
Perform installation procedure exactly as advised in [1].
Check for libaio version has been installed:-
# rpm -q libaio
libaio-0.3.99-3
We need libaio-0.3.96-3 to be installed (instead of libaio-0.3.99-3)
to turn Oracle AIO on
Find out two rpms dependent on libaio-0.3.99-3 and remove all three rpms
from the system.
Then install libaio-0.3.96-3:
# rpm -ivh libaio-0.3.96-3.i386.rpm libaio-devel-0.3.96-3.i386.rpm
Second:
Build "libaio-oracle" as root
Download libaio-oracle-0.3.0.tar.gz:
Source to libaio-oracle version 0.3.0
from http://oss.oracle.com/projects/libaio-oracle/files # cd /tmp # gunzip libaio-oracle-0.3.0.tar.gz # tar xf libaio-oracle-0.3.0.tar # cd libaio-oracle-0.3.0 # ./configure # make install Add to /etc/ld.so.conf /lib /usr/lib /usr/local/lib Restart Linux. Run control test: lio_test. Next: su - oracle Shutdown oracle mv $ORACLE_HOME/rdbms/lib/skgaio.o \ $ORACLE_HOME/rdbms/lib/skgaio.orig cp /tmp/libaio-oracle-0.3.0/libaio-oracle.o \ $ORACLE_HOME/rdbms/lib/skgaio.o $make -f ins_rdbms.mk async_on $make -f ins_rdbms.mk ioracle Startup Oracle Modify screen SPFILE of OEM concole disk_asynch_io=true filesystemio_options=asynch Click "Apply" Restart instance Now Red Hat FC2 kernel (2.6.5) will handle asynchronous I/O requests DBW0,DBW1 daemons (per Oracle Guide Lines two DBWRs should be enough). Actually, to get the work done:- We replaced file skgaio.o taking part in linking Oracle binaries $make -f ins_rdbms.mk async_on $make -f ins_rdbms.mk ioracle by /tmp/libaio-oracle-0.3.0/libaio-oracle.o References 1.http://www.idevelopment.info/data/Oracle/DBA_tips/Linux/LINUX_8.shtml |
