Improve performances

How is possible to improve the performaces of the ControlM server and EM ?
In a new linux machine installtion with oracle I have a veery slow response: a single job that do an ls command duration is about 15 minutes, slow to start, that yellow for many time and finally green.

I know that there is a manner to configure the use of temporaries directories in a ram, like ramdrive in win. But how and for witch folders?
Thanks

Hy mauriziog,
you've just to download TunningCTM6.1.03SOLARIS-SYBASE.pdf on the download part of the site (Controlm server).
All is explain about it:
the FS are the following :
in 6.1.03
$HOME/ctm/tmp
$HOME/ctm/pid
in 6.3
$HOME/ctm_server/tmp
$HOME/ctm_server/pid

just create them in tmp directorie by
mkdir -p /tmp/ctm/pid
mkdir -p /tmp/ctm/tmp
chown group:user /tmp/ctm/pid
chown group:user /tmp/ctm/tmp
delete tmp and pid directories in $HOME/ctm
and do the following links:
ln -s /tmp/ctm/pid pid
ln -s /tmp/ctm/tmp tmp

Thanks,
for the oracle DB isnt important to do the same thing?

You have information on how to do the same thing for windows?

we have only SYBASE with controlm, but i know that our DBA doing the same kind of think with the database.
i will ask for oracle and return to you

For linux I have found that there is the ramfs:
-----------------
mkdir -p /RAM1
mount -t ramfs none /RAM1
-----------------

And is possible to change the size.
In your example in solaris how work the size ?

Another question:
Have you used the ramdrive for the "STATUS" directory ?

just the swap is define as a file system with a fixed size at the start of the host, so you have to automate it by a start script, the swap desappear when stop/start the host

the swap is here an element of the system , and is define for everybody to accelerate some I/O processus.

our DBA are doing it for tempdb on sybase database, but databases can be manage by there own mecanism to in sybase or oracle.

Can you say me if this fixed size started at the start of the host is dinamical in the ram or statical?

If is dinamical the "fixed size" work as a max size and the ram used is only the size of real files in it; if statical the ram used is fixed indipendently on the real use off the TMP directory.

the swap is declared at installation of the host , but it's remove at every boot of the host. So the swap is recreate at every boot, and your own links have to be declared as a static process in the rcx.d directories (as following example)

DEV root@vega:/etc/rc2.d # more S51Controlmserver
# create tmp directories in swap
mkdir -p /var/run/ctm/pid
mkdir -p /var/run/ctm/tmp
chown ctm630d:ctm630 /var/run/ctm/pid
chown ctm630d:ctm630 /var/run/ctm/tmp
cd /prj/bcm/dev/ctm630d/ctm_server
ln -s /var/run/ctm/pid pid
ln -s /var/run/ctm/tmp tmp
# start database at boot
su - ctm630d -c dbversion
if [ $? -eq 0 ] ; then
echo "SQL Server is already running "
exit 15
else
if [ -f /prj/bcm/dev/ctm630d/ctm_server/scripts/startdb ]; then
echo "Starting SQL server for CONTROL-M"
su - ctm630d -c startdb &
echo "Sleeping for 20"
sleep 20
fi
fi

# start CONTROL-M Configuration Agent at boot
if [ -f /prj/bcm/dev/ctm630d/ctm_server/scripts/start_ca ]; then
echo "Starting CONTROL-M Server Configuration Agent"
su - ctm630d -c /prj/bcm/dev/ctm630d/ctm_server/scripts/start_ca &
sleep 10
fi

# start CONTROL-M at boot
if [ -f /prj/bcm/dev/ctm630d/ctm_server/scripts/start_ctm ]; then
echo "Starting CONTROL-M application"
su - ctm630d -c /prj/bcm/dev/ctm630d/ctm_server/scripts/start_ctm &
sleep 10
fi
exit 0
DEV root@vega:/etc/rc2.d #

this example works correctly at every reboot of this host

the defined swap :

DEV root@vega:/etc/rc2.d # df -k | grep swap
swap 2899424 120 2899304 1% /var/run
DEV root@vega:/etc/rc2.d #

For windows I have find ramdisk utilities, someone have experienced some? Some Feedbacks for windows 2003 cluster?

Post by **fyot** » 28 Aug 2007 7:45

You could find RAMDISK in the download part of the site.
That version run correctly with Windows 2003 and Control-M.

So, the result was not so important than Unix Swap memory usage.
You need a lot of available memory.
Windows already use DISK to extend its own memory.

Concerning the CLUSTER version.
I don't know. Anyway, be carefull to use only temporary files in RAMDISK.
You won't have any lost files during th switch.

Thanks for this informations about performances, good and usefull feedback.

For the CLUSTER: the temporary files is exactly the problem.
If the ramdrive can be clusterizable maybe we dont lose the temporary files on switch...
I think that in the cluster environment is not advisable.
Dont you?
