12C--ora-01033:oracle initialization or shutdown in progress

Initial installation of Oracle 12.2 RAC database.

Log in to the 1th node in the RAC database

Try to connect the PDB via scan IP (plug_test), sometimes log in to the database plug_test, but sometimes you will not be able to log in and report the following error:

$ sqlplus Robert/Robert@plug_testSQL*Plus:release12.2.0.1.0Production onThu APR -  +:Geneva: -  .Copyright (c)1982, ., Oracle. Allrights reserved.

The confusion begins here. I don't know why I can log in sometimes, and sometimes I can't log in.

Log in to the second node to view the PDB status:

SQL>Select from v$pdbs;name                           open_mode------------------- ---------------------pdb$seed                       READonlydb12pdb1                       mounteddb12pdb2                       Mountedplug_test                      mountedsql>

As can be seen from here, on the second node, the instance plug_test is in the mounted state

View Gv$pdbs:

Sql>  SelectInst_id,name,open_mode fromGv$pdbs; inst_id NAME Open_mode---------- ------------------------------ ----------         1Pdb$seedREAD  only         1DB12PDB1 Mounted1DB12PDB2 Mounted1Plug_testREADWRITE2Pdb$seedREAD  only         2DB12PDB1 Mounted2DB12PDB2 Mounted2Plug_test Mounted8rows selected. SQL>

As you can see, the above problem arises because the PDB (Plug_test) instance is turned on only in Node 1. When the PDB is connected through the scan IP, the scan IP will be routed randomly, and if it is routed to the second node, an error will not be connected.

To verify this problem, a test step has been added. Directly through the VIP connection of Node 1, you will not report the above error.

By looking at the ALTER pluggable database syntax, you can see that when you use this command, you also specify the parameter instances. If not added, the default is the local instance.

So, start the Plug_test instance from the second node.

Alter Database Open Instances=('db12c2');

If you want to start all instances, you can use the command:

SQL>alterdatabaseClose instances=all;

Or

SQL>alterdatabaseOPEN instances=('db12c1 ','db12c2');
