If you still try to use this syntax to add a database to the Data Guard broker in 26ai, beware, it won't work: ADD DATABASE ... MAINTAINED AS {PHYSICAL|LOGICAL} "MAINTAINED AS" was deprecated in 11.1 docs.oracle.com/cd/E11882_01... Time to let it go!

Claude, using the SQLcl MCP server, tried vector search with the search embedding generated on-the-fly by the ONNX runtime inside my Oracle 23ai Active Data Guard standby. Claude is impressed.

It’s heartbreaking that fantastic bands like The Bobby Lees can’t survive in a streaming economy that rewards algorithms over artistry. I’d rather pay more if it meant my money actually went to the artists I love, not industry execs and playlist puppeteers. 🎸💔 hudsonvalleyone.com/2023/11/08/t...

What use is being a rising star in the music industry when major labels and tech companies are black holes sucking all the money out of the room?

After years of using #rlwrap, I've just learned how easy it is to implement filters to modify the input and output of the commands. Perl support is available by default, and Python support can be easily installed. Better late than never. 😅

Pro Data Guard tip: Whenever you implement Data Guard in a Multitenant architecture, ensure there are no saved PDB states and control your PDBs and services via srvctl. This will save you some headaches with PDBs and services starting on the standby when they shouldn't.

Good to know: if you protect your Data Guard standby database with ZDLRA, you can use block change tracking (BCT) and real-time cascade without requiring the Active Data Guard option. #ZDLRA #dataguard #OracleDatabase
