Listener issues when shutting down DB
This is for Oracle Database 12c Enterprise Edition Release 12.2.0.1 - 64 bit Production, running on Windows 2012 R2 Server OS. I am in the process of applying JAVAVM patch 32142294 and am at the datapatch -verbose post-patch step which necessitates the database being shutdown, then started back up again in upgrade mode.
Within SQLPlus, after connecting, I type shutdown. This works, but immediately after the database is shut down, I am getting within SQL Plus - ORA-12514: TNS:listener does not currently know of service requested in connect descriptor. Despite that problem, I am able to connect to the DB in ArcGIS and SQL Developer.
