Startup

In my recent posting I have explained the startup of many PDBs at the same time.

But once you startup the container database CDB$ROOT the PDBs will stay in MOUNT status. So how do you start them during CDB$ROOT startup (or immediately afterwards) in an automatic fashion?

A startup trigger will do this job.

CREATE OR REPLACE TRIGGER startup_all_pdbs
AFTER STARTUP ON DATABASE
BEGIN
EXECUTE IMMEDIATE ‘ALTER PLUGGABLE DATABASE ALL OPEN’;
END;
/

And of course you can use the EXCEPT command option to exclude one or more PDBs from the automatic startup.

CREATE OR REPLACE TRIGGER startup_all_pdbs_except_a_few
AFTER STARTUP …
