Determine the process which is locking an Oracle account with incorrect password

Here is the procedure to Determine the process which is locking an Oracle account with incorrect password, which search from the dba_audit_session view for records with a returncode equal to 1017 which indicate a failed logon.

HIGH WATER USAGE (HWM USAGE)
##############################

To resize any datafile to reclaim some space on the datafile. Need to check for the High water mark usage and based on that Water mark we may have to resize the respective datafile to get the space reclaimed.

We had an critical space issue on the dataware house environment to reclaim the space identified the datafiles using below query and resized the respective datafiles where we can get some space through this process.

Note: This is for a temporary Fix and have to plan for a better storage.
