Last night I needed to replace a harddisk on my oracle server to another one with more capacity. For complete this task, I did the folowing.
1) Disable Oracle AutoStart on Linux.
2) Shutdown the server
3) Put the new HD, partitioned, formated, and copy the files as ROOT user.
4) Shutdown the server again, remove the old HD, change FSTAB do point the oracle mount points to the new HD
5) Poweron the server, change the permissons to oracle folder (/u01 and /u02. Oracle Instalarion Folders and binaries are on /u01 mouting point)
6) Change owner on /u01 and /u02 to oracle, recursivelly.
7) Change filemode on /u01 and /u02 to 775, recursivelly.
8) Starts the oracle from the new HardDisk.
The database started fine. EM also stared with no problems.
But, when EM try to execute a JOB, that is a operating system command, it doesn't execute, and tells that it "cannot read error message from input".
I think that could can be happening because the permissions that I changed. Does anybody know what could be done to solving this?
