Is the SQL Developer running on the Data Manager Server?
If not, then...
Can Data Manager PING the IP address and get a reply?
If yes, then there are more parameters you may need to add to that JDBC URL.
It is the Schema name, if you login with an ID that does not match the schema name you might need to add something like this...
(This example is for DB2, but I think you can do this for Oracle also.)
How to supply a schema name
When a data source is a database and is running on Oracle or DB2, you must supply the schema name so that the Data Adapters can access the database. If you cannot log on as the schema owner, perform the steps described in one of the following sections to supply the schema name to Data Manager.
Solution for DB2
When you add or edit a data source within the Data Manager user interface, you can specify the schema name using the JDBC URL (optional) field, as follows:
dbc:db2://hostName:port/database_name:currentSchema=SCHEMA_NAME;
For example,
jdbc:db2://host1.devlab.ca.com:50000/TDW:currentSchema=ITMUSER;
Important: Be aware of the following information
- The schema name is case sensitive and must be specified with all capital letters.
- The semicolon at the end of the statement is required.
- The parameter currentSchema is case sensitive as shown.
