And the third and latest issue we got today with RAC installation was the following error while running rootdelete.sh which is used to disable clusterware applications :

[code]

[root@node1 install]# srvctl
/u01/oracle/product/10.2.0/crs_1/jdk/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
[root@node1 install]# ./rootdelete.sh
/u01/oracle/product/10.2.0/crs_1/jdk/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
[/code]

Then we got the same error while using srvctl utility to manage configuration information.

After a little investigation, we’ve found that we need to edit two executables 1. srvctl and vipca (as it’s called when running rootdelete.sh) and comment the line where LD_ASSUME_KERNEL parameter is set

[code]

       then
            LD_ASSUME_KERNEL=2.4.19
          #  export LD_ASSUME_KERNEL
[/code]

After commenting the line, we were able to bypass the above mentioned error

You can refer the following metalink note for more information:
