I use toad to monitor both rac and non-rac databases. I customized my session browser to show the column INST_ID.
This works ok when working with a rac database but leads to the error ORA-00904: “INST_ID”: invalid identifier when changing to a non rac db and then subsequently to toad being closed.
Is there a way to change this behaviour? Can I write sort of a trigger in toad which recognizes db type and then changes column visibility?
Any help appreciated.
