Starting Oracle Database 12c Multitenant PDBs
To also start all pluggable databases when the container database starts, you can do:
connect / as sysdba create or replace trigger sys.after_startup after startup on database begin execute immediate 'alter pluggable database all open'; end after_startup; /
To erase Oracle installed files in case of error and try to reinstall do the following;
[root@laptopcentos stage]# cd /u01
[root@laptopcentos u01]# ls -atlr
total 12
dr-xr-xr-x. 21 root root 4096 Sep 30 14:03 ..
drwxrwsr-x. 3 oracle oinstall 4096 Sep 30 16:45 .
drwxr-sr-x. 4 oracle oinstall 4096 Sep 30 16:51 app
[root@laptopcentos u01]# rm -fr app
[root@laptopcentos u01]# cd /u02
[root@laptopcentos u02]# ls -atlr
total 12
dr-xr-xr-x. 21 root root 4096 Sep 30 14:03 ..
drwxr-s---. 3 oracle oinstall 4096 Sep 30 16:54 app
drwxrwsr-x. 3 oracle oinstall 4096 Sep 30 16:54 .
[root@laptopcentos u02]# rm -fr app
[root@laptopcentos u02]# cd /usr/local/bin
[root@laptopcentos bin]# ls
coraenv dbhome oraenv
[root@laptopcentos bin]# rm -fr *
[root@laptopcentos bin]# cd /etc
[root@laptopcentos etc]# ls ora*
oraInst.loc oratab
[root@laptopcentos etc]# rm -fr ora*
[root@laptopcentos etc]#
Now go back to run the oracle installer.
