ORA-06512: use PL/SQL stack lines to find the real exception
This message supplies source-location context in an error stack. The primary exception usually appears elsewhere in the stack.
Environment and inputs: Oracle Database 19c baseline · SQL*Plus-compatible SQL unless RMAN, DGMGRL, ADRCI or a host shell is specified. Check release, patch level, edition and container first.
Start with this diagnostic
Use the stated SQL, RMAN, DGMGRL or host shell and replace sample names with approved targets. DBA and V$ views need authorized catalog access in the correct container. Do not grant broad privileges for an example.
SELECT line, text FROM all_source WHERE owner = 'APP_OWNER' AND name = 'APP_ORDER_API' AND type = 'PACKAGE BODY' ORDER BY line;Read the result
The source lets an authorized developer locate the reported line in the deployed object. Compare the deployed version with the application's release.
Resolve and verify
Start with the primary error, follow the backtrace to its failing expression and reproduce with sanitized inputs. Fix the cause and preserve meaningful exception propagation.
Operational precautions
Do not treat ORA-06512 itself as a single root cause or suppress the whole stack.
