ORA-06597

Error Message

Failed to increase the session's call stack memory tostringbytes at a depth ofstringcalls. (The current maximum isstringbytes.)

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.
