Operating Systems AIX fr and sr (from vmstat output) values are very high Post 302492300 by zxmaus on Monday 31st of January 2011 01:16:35 AM

Hi,

it doesn't matter how high the numbers of sr/fr are by themselves - the only important thing here is the ratio - sr:fr - it should genuinely not be higher than 4:1 - as that is about where performance issues start - if it goes to 10:1 or higher than your system is spending more time freeing up memory than doing real work. In your case it is pretty much 1:1 what is just fine.

Your output above would be more helpful if we would know how much physical memory you have - ideally avm (in 4k pages) should not exceed 75% on an oracle box for best performance since oracle is a process based DB and every process / connection needs some memory on top of the SGA that is set within oracle - if it goes above 85% or if your free list drops against 0 you are in serious trouble as well - or if you start seeing pi/po values ...

Page faults are no reason for concern after all - they only mean that your box is doing work (and using memory pages).
What I would consider reason for concern is your very very low free list. If this is NOT an asm system, than I would recommend to mount your /dumps filesystem with noatime and rbrw option, all other oracle related filesystems with noatime option as well - and to have your DBAs switch oracle to SETALL. This will give your system a lot of desperately needed memory back.

You should as well consider exporting AIXTHREAD_SCOPE=S .... either as system wide variable in /etc/environment or at least in the oracle .profile

If you want more tips please post the vmstat -Iwt output again including your resources, vmstat -s and vmstat -v outputs.

Hope that helps
kind regards
zxmaus

make-jpkg builds a Debian package from the given Java distribution FILE. Supported java binary distributions currently include: * Oracle (http://www.oracle.com/technetwork/java/javase/downloads) : - The J2SE Development Kit (JDK), version 6 (update >= 10), 7 - The J2SE Runtime Environment (JRE), version 6 (update >= 10), 7 - The J2SE API Javadoc, version 6 (update >= 10), 7 (Choose tar.gz archives or self-extracting archives, do _not_ choose the RPM!) The following options are recognized: --full-name NAME full name used in the maintainer field of the package --email EMAIL email address used in the maintainer field of the package --changes create a .changes file --revision add debian revision --help display help text and exit --version output version information and exit Download a supported Java RE or SDK or API tar.gz or self-extracting archive from http://www.oracle.com/technetwork/java/javase/downloads and execute make-jpkg file with the downloaded file. The program asks the user for additional information and builds a Debian binary pack- age in the current directory. The program requires about 200 MB free disk space in a temporary directory. The temporary directory defaults to /tmp but you can specify an alternate directory by setting the environment variable TMPDIR. EXAMPLE
To install Oracle(TM) 7 Standard Edition JDK, download a release - 64 bits version of update 2 from http://www.oracle.com/technet- work/java/javase/downloads/jdk-7u2-download-1377129.html in this example - and invoke make-jpkg: make-jpkg <path_to_download_directory>/jdk-7u2-linux-x64.tar.gz This generate a Debian package in the current directory, that can be installed using dpkg: dpkg -i oracle-j2sdk1.7_1.7.0+update2_amd64.deb When you're done, you can delete initial download as well as generated package: rm <path_to_download_directory>/jdk-7u2-linux-x64.tar.gz oracle-j2sdk1.7_1.7.0+update2_amd64.deb ENVIRONMENT
TMPDIR base directory used for temporary files (defaults to /tmp) J2SE_PACKAGE_FULL_NAME full name used in the maintainer field of the package; if none is supplied then the default of "Debian Java Maintainers" is used. J2SE_PACKAGE_EMAIL email address used in the maintainer field of the package; if none is supplied the default of "pkg-java-maintain- ers@lists.alioth.debian.org" is used. SEE ALSO
