I have a database on my server which I could like to have on my laptop so I can use it for development. Is there a way to do this? I was using the default SQLite database with Django but now I'm using PostgreSQL which isn't part of the repo.
How to maintain Postgres to Oracle data synchronized?
Currently we are trying to mimic the Oracle to Oracle database link but with Oracle to Postgres. I know that we can add FDW wrappers to connect but the latency is huge.
I have also checked AWS DMS process but it has lot of data type issues when data load and synchronization from Oracle to Postgres happens.
Can someone tell a better way?
Is there any feasibility from Oracle to have a connection established to DB2 database so that I can query on DB2 database and generate reports from Oracle Apex?
OR
Is it possible to create a View in Oracle from a remote DB2 database?
OR
What options do i have in order to develop reports in Oracle Apex from the data i have in DB2 database?
(I know, this is an old question and you've already found a workaround. Anyway,) the keyword you might be interested in is gateway. This is Oracle 10g Database Gateway for DB2/400 Installation and User's Guide. I don't know which database you use, but - if 10g is not the one, I hope you'll manage to find the right documentation.
Shortly: after installing the gateway between Oracle and DB2, you'd create a database link. Then, in your Oracle schema, create a view that selects data over that database link from DB2 database. Finally, fetch data in Apex from the view.
As i didn't find a way to directly connect to DB2 from Oracle PL/SQL, i used a work-around. As this is a reporting tool, we are ok to have this tool running with the data which is 1 day off, we did the following:
1) Extract the data required from DB2 database to CSV files. We used a DB2 command which can be run at command line to extract the data into a CSV
2) Then we imported the data into Oracle tables using sqlldr
We have a windows server, where while installing Oracle, one database has been specified and created. I want to create an application in ORACLE on the same server, but I want to create and use a different database for this application. My mentor says that the server can hold only one ORACLE database and my request can not be implemented. Is there a way out of this ?
I have installed Tableau server in my PC. I am trying to connect Amazon Redshift server from tableau server directly like connecting redshift from tableau desktop. I am not found any options for it. Is it possible? and i am using tableau server trail version. Thanks.
Tableau Server is used to store published data connections and workbooks created in Tableau Desktop. Whilst it is possible to edit an existing data connections, it is not possible to create a brand-new data connection on Tableau Server.
When publishing a workbook or data connection that uses Amazon Redshift, make sure that the appropriate driver is installed on the Tableau Server machine (Tableau Support drivers page)
