ORA-07251: spcre: semget error, could not allocate any semaphores.
Cause : Semget failed to even allocate a single semaphore. Either they are all in use or the system is not configured to have any semaphores.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Check to see if all semaphores are in use. Check to see if system is configured to have semaphores. Check errno.
Well, the reason for above error is that i have taken the above script from a 11g database and running it on 10g database. 11g has bring some changes in password management. Below code is executed on 11g and user created successfully, which is expected result.
