Is it possible to create Postgresql data source in Oracle Visual Analyzer? - oracle

I'm using OBIEE 12.2.1.2.0 and I want to create a connection to Postgresql there's no database type for Postgresql in 'Add a New Connection' form.
I would appreciate if any body help me to know whether VA supports Postgresql connections.

Since it's 12.2.1.2 all there's to be said is: The version doesn't have it yet. DV has it already though so the upcoming 12.2.1.4 on-premises should be up-to-date again as well.

Connect to Oracle with TOAD

Is there any way to connect to Oracle using TOAD without installing an Oracle client?
If you check Installation Guide, Database requirements specify:
An Oracle client must be installed and configured on the system where you are running Toad (...)
Therefore, I'd say no is the answer to your question.

Unable to connect to Oracle using SSMA for Oracle

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.

PostgreSQL to Oracle Database with Oracle GoldenGate 11.2.1

I've spent 2 days to sync postgresql database to oracle. Read few books, googled many times..
1. I have setup PostgreSQL on CentOS 6.5 (A) also installed oracle database on this VPS. copied GoldenGate to it.
2. I have already setup 2 oracle VPS using Goldengate and setup as Source (B) and Target (C). I'm trying to sync PostgreSQL to Target VPS.
3. GoldenGate runs on A server without error.
The problem is when I setting up it requires ODBC config (page 14). I'm new to PostgreSQL so little confusing for this..
Also when I google i find only to postgresql from oracle.
Main doc I'm following is http://docs.oracle.com/cd/E35209_01/doc.1121/e29642.pdf
Actually I have found Oracle Golden Gate new features https://blogs.oracle.com/dataintegration/resource/2013-DIFamily/OGG_WinUnix_Rel_Notes_11.2.1.0.7.pdf
Oracle Golden Gate don't support what I want to do.
They say:
Oracle GoldenGate introduces support for PostgreSQL. This support includes the mapping, manipulation,
filtering, and delivery of data from other types of databases to a PostgreSQL database. Oracle GoldenGate
does not support the capture of data from PostgreSQL to other PostgreSQL databases or to other kinds of
databases.
GoldenGate does not support Postgres as a source - only target.
Check out Attunity for what you are trying to do.
Postgres support was only for delivery in Oracle GoldenGate 12.2. Oracle is working on a full capture/delivery support for Postgres. It will be out in a later release post 19c. Please check the OTN website for versions.

Issue with Oracle ODBC

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

VB and Oracle connectivity

What are the steps to connect to Oracle 9i with VB6? How can I use modules and stored procedures in VB6 and how can I call an SP?
What is the method to use ADO which is helpful to insert, update, search and delete the items from the front end?
You will need ADO to connect to Oracle (add reference to microsoft activex data objects library).
You need to know where is the Oracle Instance hosted alongwith username and password?
The connection string for Oracle can be found from www.connectionstrings.com
ADODB.Connection is the one that you will need to establish the connection.
Connection has Execute method - which you can use for any insert/update/delete statements.
Now, read some documentation on ADO object library from MSDN.
And, write the code by yourself.
You can choose between the Oracle OLEDB driver (which I think comes with the Oracle client install mentioned by YogoZuno) or one from Microsoft (can't remember if it was just a standard microsoft oledb driver or one released with a nod towards oracle): in any case, the Oracle OLEDB driver is far better.
You will also need to have the Oracle client installed on your PC, along with an appropriate TNS Names file. Also, be aware that there are some minor functional differences between various versions of the Oracle 9 client - I had some issues under v9.2.0.1, that did not occur under v9.2.0.7.
