I have an oracle database installed on different server.
Now I want to install ORACLE APEX on my PC but I always fail, since it can't locate the SQLPLUS command.
Is it possible to install it this way or not?
Hope you can help me with this.
Thanks
Apex is installed in an Oracle database, which means that you have to have access to it.
You can't install Apex on "your PC", while database is installed on a remote computer (database server).
Therefore: if you don't have access to the database itself (as a privileged user, SYS), you'll have to ask your DBA to install Apex for you. After it is done, you'll be able to use it.
Alternatively, if you install e.g. Oracle Express edition (XE) on your computer, you'll get Apex along with it. Then you can upgrade it to the latest version (or whichever version you want). Using a database link from user in your XE database to your "real" user in the remote database, you'd be able to access data stored over there.

I installed Oracle Database 19c and was able to connect to the database using sqlplus in command line. However when I try to use SQL developer I'm unable to connect. I noticed I don't have any listener service like I did when I had Oracle Database 21c installed on another computer. Is this why I can't access it on SQL developer? And if so how do I create that listener?
Access the database through SQL Developer.
(I don't have the reputation to comment, so I'm posting this here.)
Just wanted to say that I just encountered the same issue.
I installed Oracle 19c on Windows as "Software Only".
I used dbca.bat to create a database with a single pluggable database through the "basic" configuration. In the past I've gone through the "advanced" configuration, and I'm wondering if that's what lead to this.
So now I'm dropping the database and will try re-creating it to see if using the advanced DB installation provides a listener.
Edit
After deleting the database, then going back through the DB installation in dbca.bat via the "advanced" installation option, I noticed that the listener configuration was actually disabled by default, and I had to choose to add a listener.
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.
I'm trying use Microsoft SSMA for Oracle to migrate a database onto Azure SQL, but I can't get it going. I've double checked the server name, server port, Oracle SID, password... everything. No matter the type of entry screen I use, I can't get it to connect to the on-premise Oracle instance.
I'm pretty sure the login information is all correct, and I should have a working connector to Oracle since I connect to it from TOAD on a daily basis. I tried installing Oracle libraries per previous posts but not sure if I did it successfully because the issues still remains.
What are the troubleshooting steps I should take in order to make this work?
Log in screen:
Error 1:
Unable to find specified provider.
Compatible Oracle Data Access Connectivity libraries were not found on the machine. You can install them from Oracle product media or download it from Oracle web site.
Error 2:
Connection to Oracle failed.
ORA-01017: invalid username/password; logon denied
Error 3:
Connection to Oracle failed.
Network Naming: No LDAP server detected or configured
After a few more days of debugging, I was finally able to get SSMA to work. This answer helps to document my solution for personal use, as well as hopefully answer anyone else's question in the future.
After looking at the list of prerequisites to have SSMA running, I saw that I needed to have a correct Oracle client running. After some internal discussion, it was likely that the Oracle client SSMA needed was different than the one my computer already had for TOAD. The .Net provider for the TOAD connectors was probably not useful for SSMA.
We run Oracle 11g but I had to install Oracle 12c because 11g did not support Windows 10 apparently. Not too much of a roadblock here.
I found this guide to install Oracle client 12c pretty helpful. Shoutout to my alma mater.
Unfortunately the installer kept freezer, but using this former post, I was able to bypass it with the windows command:
setup.exe -ignoreprereq -J"-Doracle.install.client.validate.clientSupportedOSCheck=false"
After that, I saw different error messages when trying to connect SSMA. I kept trying different options with my logins until it worked. Provider: OLEDB Provider, Mode: Standard.
After being granted the appropriate permissions, I was finally able to access our internal tables and objects.
It was a pretty annoying question with a lot of rabbit holes along the way, but it was definitely worth it, being able to translate all our Oracle schemas to Azure SQL with a few clicks. Hope this helps!
Make sure to validate all steps mentioned below before going to install Microsoft SQL Server Migration Assistant for Oracle.
Make sure you have already installed SQL Server instance that will host the migrated database. Also keep in mind that you are not installing SQL Server Express edition to host the migrated database.
You must have sysadmin account to install SQL Server Migration Assistant for Oracle.
Make sure to install SSMA for Oracle on the server that will host newly migrated database on SQL Server.
It is recommended to install Oracle client software on your target system where SQL Server Instance is running.
Make sure your windows server has Microsoft Windows Installer 3.1 or a later version. Port 1434 should be open.
For more details, You can reference: How to Install SSMA for Oracle to Migrate Oracle Database to SQL Server.
Here's the Azure Database Migration Guide: Migrate Oracle to Azure SQL Database. As you prepare for migrating to the cloud, verify that your source environment is supported and that you have addressed any prerequisites. This will help to ensure an efficient and successful migration.
Connect to Oracle with Oracle Client Provider.
Azure also has other way can help you migrate Oracle database to Azure SQL database, such as with Azure Data Factory. If you still has the connect error. I think you can try to use it. Please reference this tutorial: Copy data from and to Oracle by using Azure Data Factory.
Hope this helps.
I have a server with an Oracle Database. Using Navicat I can connect to the Database and see the database tables, run queries etc.
I am trying to add ODBC support for Oracle to be used with Crystal Reports.
What I have done so far:
I struggled to install instant client and get it working as shown in some guides. As suggested I downloaded ODAC which bundled on the Oracle ODBC Driver and Instant Client etc.
After installing I had Oracle installed in C:\app\Administrator\product\12.1.0\client_1
I added two Environmental Variable:
%ORACLE_HOME% to go to C:\app\Administrator\product\12.1.0\client_1
%TNS_ADMIN% - to go to C:\app\Administrator\product\12.1.0\client_1\Network\Admin
Once added, I then went to control panel->Administrative Tools->ODBC.
I clicked system DSN and added the connection. The connection was successful.
However, when selecting the ODBC connection via Crystal Reports, the Database is showing the database functions (I assume stored functions as they appear in the functions section for the DB in Navicat). I cannot however, see the actual database tables.
Has anyone else experienced this issue and if so does anyone know how to resolve this. Many thanks for your time
I am a little lost with the current documentation I have.
I am trying to access an oracle server within a Network, using a Debian Box. Ideally, what I'd need to do is to cron job something into SQL plus, so it performs periodically.
My scripts are ready, but I am not sure how to do the instalation part, or what to install in order to get access to SQLPlus. Does I need the full-fledged oracle client? Oracle XE? Will SquirrelSQL work?
Thanks a lot!
You just need the Oracle client, not the full database install. You can download it here. From the sound of it, you don't need the full client.
