CAUSE

The filesystem inodes are exhausted.

Solution:-

 I rebooted my machine and got following messages which pointed to some
errors encountered during filesystem check and instructed to run fsck manually.

[root@sonu ~]# init 6

Checking filesystems

/: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
*** An error occurred during the filesystem check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance (or type Control-D to continue):

– I entered password for root to initiate filesystem check.
As a result I was prompted multiple no. of times to allow fixing of  various filesystem errors.

(Repair filesystem) 1 # fsck
Fix(y)?
- After all the errors had been fixed, filesystem check was restarted

Restarting e2fsck from the beginning...

/: ***** FILE SYSTEM WAS MODIFIED *****
/: ***** REBOOT LINUX *****
- After filesystem had been finally checked to be correct, I exited for reboot to continue.

(Repair filesystem) 2 # exit

– After the reboot, I could successfully connect to my database as sysdba .
