i solved my problem.
Actually when i going to execute 'runInstaller' to install oracle 9i on centOS 3.4 , it gives me following error:
Error occurred during initialization of VM
Unable to load native library: /tmp/OraInstall2003-10-25_03-14-57PM/jre/lib/i386/libjava.so:
symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
To resolve this, I download the patch p3006854_9204_LINUX.zip from
http://metalink.oracle.com/. See bug 3006854 for more information.
To apply the patch, run
su - root
# unzip p3006854_9204_LINUX.zip
# cd 3006854
# sh rhel3_pre_install.sh
Applying patch...
Patch successfully applied
After this my Oracle Universal Installer will run smoothly.
I am not sure whether this problem arises on slackware or not.
Good Luck....
