Oracle Error Message
ORA-06597: Failed to increase the session’s call stack memory to string bytes at a depth of string calls. (The current maximum is string bytes.)
Reason for the Error
PL/SQL program execution used more call stack memory than permitted.
* Ask your DBA to increase the maximum allowed call stack memory.
* Decrease the amount of call stack used by the program. This may be accomplished by using fewer, smaller local variables, or by limiting the depth of function call nesting.
