I've no idea what that menu entry is for. It may be a hangover from JDeveloper.
If you want to add support for third party databases, you need to download the JDBC libraries and then use Tools|Preferences|Database 3rd Party JDBC connections.
This is covered reasonably well in the help file under MIgrating Third Party Databases.
That menu is to manually configure drivers. It also exists in the documentation but does not appear on my install of Oracle Sql Developer. I need to manage the 3rd Party JDBC Connection that I have because Oracle assumes it to be in a specific format when, in fact, the format it assumes is wrong. Through the 'Manage Libraries' menu I can manipulate the JDBC URL in order to connect to my DB2 iSeries database. If there is a different menu that you can point me to in order to manually configure my Third Party JDBC Connections, that is what I need. Since we currently do not use the DB2JCC.jar file, I cannot use that to connect. I need to use the configurations based on the JT400.jar file. I have verified that this works for two other Database clients, Visualizer and SquirreL.
I've checked my installation of JDeveloper, and that menu option is there. It is used to manage Java libraries generally and has nothing to do with JDBC. The SQL Developer documentation is wrong.
I've already pointed you at the preferences section for managing third party JDBC libraries, and to the help section. If you don't want to follow that, then you are on your own.
Note that DB2/ iSeries is not a supported third party database in SQL Developer.
In addition to what Jim notes, if you do not see Tools > Preferences... > Database > Third Party JDBC Drivers then your install may be corrupt. But that is almost a moot point given that DB2/iSeries is not supported.
I have already used that menu and looked at the help section. I have added the jar containing the driver, jt400-6.7.jar, and on the menu that you can get to by navigating to Tools -> Preserences... -> Database -> Third Party JDBC Drivers, the driver is there where I added it.
I can put information in on the DB2 tab but the format is wrong. It is using the format assumed by the DB2JCC.jar which is not the same as the jt400.jar. As I have previously stated. DbVisualizer, for example, has a menu called 'Driver Manager' in which you can manage drivers that will connect you to your database. Here I am able to provide the URL format which will let me connect to the database.
I thought that V4.0 was able to connect to DB2/Iseries. There is a DB2 tab and information regarding DB2 databases in the help menu. Is this only for non-iSeries databases?
Is this only for non-iSeries databases?
Actually, it is only for the DB2 LUW family, not iSeries or z/OS. The release notes for 3.2.2 and earlier had a section on Third Party Databases
that seems to have been dropped in the 4.0.x release notes. In turn, that includes a link to Supported Migration Platforms
which includes a list of supported source databases. But there is another forum specifically for migration issues, and I found the following discussion on an alternate approach for using SQL Developer with iSeries -- perhaps it may be useful to you iSeries to Oracle migration help?
It looks like that implementation centers around being able to install a specific driver on the machine of the iSeries database. I do not have such access. We use, to my understanding, the jt400.jar on the machine the DB is installed on. I may just be out of luck when it comes to using Oracle's Sql Developer.
