Oracle Scenarios Interview Question:
Explain If the SQL * Plus hangs for a long time, what is the reason?
Submitted by: AdministratorYou are running a cartisian query, typically by mistake. Make sure every table has a join criteria specified for it.
You are working on a table with 100+million rows.
The database server is busy doing a backup.
Check the disk IO for the process that appears hung and if the disk IO is increasing every 5-10 seconds then the job is not hung, it is just taking a while to complete.
