I'm creating a single instance by this instructions. Everything works well but the DB is created with CDB. I would like to create a simple-non-cdb oracle instance. How can I do it?
change those in dbca.rsp.tmpl
createAsContainerDatabase=false
numberOfPDBs=0

We have a custom inventory system, for tracking all of our database, including Oracle v12 and v19 based databases. But as our DBA team has work with Container Databases (CDB), we need to identify, which one is a standalone or container, but we don't have any option to connection to the, due to our security policy.
Is there any way to Identify oracle Container Databases (CDB), without connecting to them?
As after reviewing Oracle official documentation: https://docs.oracle.com/database/121/ADMIN/cdb_mon.htm#ADMIN14174.
It seems that it's not possible, as the documented clearly mentioning, that first, it's necessary to connect to the database, and only then to run the following command: SELECT CDB FROM V$DATABASE;
And if the CDB column returns YES, the current database is a CDB. and NO, if the current database is a non-CDB.
Wonder if this can be achieved. Install Oracle APEX onto a Linux VM and have Oracle DB residing on a separate server to point to it. Is it possible to install Oracle APEX without Oracle currently installed on the same box? Can't find any documentation on the Oracle site for this setup.
No. Application Express (APEX) runs out of the database itself. APEX is a collection of PL/SQL packages and tables.
Now the web tier could most definitely be moved to another machine (linux even). That would be something like Oracle REST Data Services and Apache Tomcat.
Good Day. I have a situation which I am unsure of how to solve. I have searched numerous places and found nothing concrete.
The scenario:
I have 3 Oracle Apex 5 applications running on a single server using Oracle Express locally in order to run the app. I however had to go to Oracle 12c which is installed as a separate instance on the same server and it's listener is now listening on 1522 where XE is still listening on 1521.
I am needing to find a way to export the schema, tables, apps etc. into 12C from XE, then simply configure the apps to connect to the 12C instance and no longer on XE. I can then remove XE completely.
I know I am supposed to post what I have tried, but simply have no code, I have tried to do a export DDL but the script does not seem to carry the Schema data at all.
Question: How can I migrate everything on the XE instance to the 12C instance without breaking either instances.
Any direction would be appreciated.
Two steps: data(base) migration & (Apex) application migration.
The simplest way to move data is to perform export and import. Although you can use the original EXP and IMP utilities, consider using modern Data Pump Export and Import.
EXP and IMP are somewhat simpler; export (DMP) file is created on your disk
Data Pump requires you to create an Oracle directory (object) which points to a directory on the disk. As it is XE installed on your computer, no problem if it is, for example, C:\Temp
syntax is very similar in both cases, especially if there's nothing fancy in your data
The second step is application migration; you should first install Apex in the new Oracle 12c. Make sure it is up and running (create a workspace, assign a schema (you've just imported) to it, create a developer).
Then export the Apex application(s) - if there are only a few of them, a simple way is to do export from the application itself (you'll see the "Export/Import" button in the "main" application page within the App. Builder). Follow the wizard. The result will be a plain textual (.SQL) file.
In Apex on 12c, revert the process - do the Import by navigating to previously exported .SQL file, follow the wizard once again. Once the import is finished, you should be able to run the application.
Good luck!
I want to migrate database server from Oracle 9i to Oracle 11g (WebLogic version is 8.1 SP5).
After migration, WebLogic version will remain the same. Only database gets changed.
How can I achieve this?
Is taking DB dump before migration and importing dump after migration enough for this task?
Or do I need to do other things as well?
Thanks.
Yes, most likely a DB dump will do the trick. Oracle data types are backward compatible, so, you are covered.
Just wondering how do I check if a backup is running on an Oracle database. I am on version 11.2.0.2
That depends on how you are doing backups. Are you using RMAN? If you are using recovery manager you can use the corresponding database views like V$RMAN_BACKUP_JOB_DETAILS or V$RMAN_BACKUP_SUBJOB_DETAILS
