dear sir; i am using centos 3.1 on a test server . i install oracle 10g and it works fine . but after installing a patch for oracle i have the following error : error while loading shared library /etc/libwait.so can't open shared file and after rebooting i have the same error plus " kernel panic " so is there any thing that i can do to get my system working ? and from where can i get the aproperate oracle patchs for centos ? thanks in advance . khaled
