I installed Oracle database 11g many years ago. I am now trying to get more current with 19c. I downloaded the 19c install from the Oracle website (WINDOWS.X64_193000_db_home.zip). Extracting the archive created a WINDOWS.X64_193000_db_home directory. OS is Win10, by the way.
From inside the extracted directory, I ran setup.exe. I specified that the database was to be installed in d:\u0\ directory. The contents of the u0 directory look nothing like I expect it to.
I do not know what is going on.
The database does run and I can work with the database with sqlplus but there is no listener. Netca claims that the listener is created but "lsnrctl status" the command line returns the following (I have to enter this by hand so there may be typing errors):
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=[computer_name])(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-OO511: No listener
64-bit Windows Error: 61: Unknown error
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-OO511: No listener
64-bit Windows Error: 2: No such file or directory
I cannot find the definition files because I do not see any of the normal paths, at least any that I can recall.
