Thanks All...

This problem is occurring not only during particular procedure execution,We're getting this error almost for all procedures during its execution.

These procedures were executing successfully last week,but now
only it's giving problem.

These two errors are occurring during procedure exec,

Error-1
ERROR at line 1:
ORA-01722: invalid number
ORA-06512: at "CW.INTRATE", line 285
ORA-06512: at line 1

Error-2
ERROR at line 1:
ORA-00942: table or view does not exist
ORA-06512: at "CW.INFORMATION", line 460
ORA-06512: at line 1
I doubt that some corruption has occurred in the database.
How to fix this problem so that procedures will execute successfully?

We're getting these errors not during procedure compilation but only during execution.

Thanks...
