I’m trying to perform a Diff on two DB2 schema’s and when I try to select my source and destination connections it doesn’t list my NEW connection. I’m using latest version. I can connect to DB2 manually and query as well, but just can’t sect that connection during database Diff.
Where are the connections saved in sql
Developer?
That feature is reserved for Oracle Database connections.
DB2 connectivity is provided for migrations to Oracle only.
We have limited support for DB2 in the Data Modeler (which is part of SQL Developer), and you can compare models, but the generation of DDL synch scripts is reserved for Oracle data models only.

I would like to develop a ER diagram using DBeaver (Eclipse plugin) for a database that doesn't yet exist. Also, the database server doesn't exist.
Can DBeaver be used to develop a ER diagram without connecting to an existing database server? I can only find documentation for working with an existing database or connecting to an existing database server.
Nope, sorry.
DBeaver tools are always associated with the current connection.
For example, in the ERD when adding tables, DBeaver often sends requests to the database of foreign keys.
You can use standard sample SQLite database in DBeaver for experiments.
I want to configure IBM DB2 on iseries AS400. The issue is I'm not getting the proper tool for AS400 and I've already installed Data Studio for configure DB2.
I don't have any knowledge regarding AS400 and I'm fresher for IBM technology.
I have already ODBC drivers of iseries. Please help me to find out iseries AS400 setup tool.
DB2 is integrated into OS/400 and all of it's following OS's. To configure DB2 on these platforms, perform a power-on maneuver. If it is already turned on, then DB2 is configured.
BTW, you probably don't have an AS400 but something newer. The hardware is likely Power System or Pure System, and the OS is likely IBM i.
Once you get a SQL connection to the AS400 aka system i aka iseries. Configure the DB by executing this SQL statement in Studio.
create collection myas400SQL
This will create an as400 library named MYAS400SQL that has the mumbo jumbo journal automatically added meaning this will work like every other SQL database with commit rollback transactions...
Lets try it.
CREATE TABLE myas400sql.mytable (myfield char(1))
Table mytable can handle commits and rollbacks like any other db you may have used.
Happy Friday.
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
I know that SQL Server has linked server that allow it to connect to other database and execute query. Now I am using firebird. I wonder if firebird has its "linked server" to access other databases. Thanks!
Firebird doesn't have a linked server feature. There is a limited method for accessing other Firebird databases (either remote or locally) using EXECUTE STATEMENT, however this only supports Firebird database, and you need to provide the data source information on each invocation.
Suppose I have multiple Oracle databases in the same server. Now I want to connect to particular database and query a table just like SQL Server 2008. How to start particular Oracle database?
If you are using SQL*Plus, the most common syntax for opening a connection is
sqlplus user_name/password#tns_alias
In this example TNS_ALIAS is the TNS alias for the particular database you want to connect to (most likely "XE" based on your followups to inium's answer). If you want to connect to a different database, you would need to specify a TNS alias for that specific database.
Note that since you are coming from a SQL Server background, the SQL Server definition of a database is rather different than the Oracle definition. What SQL Server calls a database is similar logically to what Oracle calls a schema (and similar physically to what Oracle calls a tablespace). So when you're dealing with Oracle, it's much more common to have many schemas in a single database than to have a large number of databases on a server. This is particularly true if you're using the Express Edition (Oracle XE) where you're generally limited to one database per machine.
go to cmd and type sqlplus <database-name>/<database-password>
You can use SQL Developer, it's similar to SQL Enterprise Manager 2005. Just create a new connection using the db user name and password.
