You do it in the OS user config file such as. Therefore, change the default value of shell-variable ORACLE_SID. To change the default service you connect to, change the default value of instance. The listener-config file name listener.ora associates instance with service. Otherwise, it cannot, and you must perform explicit-connection request, supplying the third operand. If set, then it can handle implicit-connection request. It checks the value of shell-variable ORACLE_SID. It checks whether the instance name has been set. In handling the implicit-connection request from the same host, The listener is the one that initially responds to connection request. Consequently, the listener is on the same host. ![]() Implicit connection applies only when the client-host and server-host are the same. In an explicit request, you supply three operands like sqlplus In an implicit request, you ignore the third operand. The correct question is 'How do I change the default service'? Oracle DBMS offers two types of connection request: explicit and implicit. Setting both to different values is a particularly painful problem to diagnose, particularly over the phone with a person who doesn't really understand how Oracle works (been there, done that). The reason that you should always use an explicit connect string is that you have no idea whether the user has set TWO_TASK, ORACLE_SID, both, or neither nor do you know what they might be set to. ORACLE_SID takes precedence over TWO_TASK. The first is TWO_TASK, which uses the naming lookup, and the second is ORACLE_SID, which assumes that the server is running on the current machine. There are also two ways to specify a default server via environment variables. You can also specify an Oracle connection string as SERVER, but pretend you can't. The best way - the one that you should always use - is This will use the Oracle naming lookup (tnsnames.ora) to find the actual server, which might be on a different physical host every time you connect to it. ![]() From there click the option New Database.To expand on kerchingo's answer: Oracle has multiple ways to identify a database. To create a new blank target database connect to the server where you will be restoring the new database and right-click Databases. Though it is not necessary to create a new blank target database for the restore, I find that doing this further minimizes the risk of overwriting the existing database. There are a couple different ways to go about this. Let’s assume you have already created a backup of the database. The steps outlined below will walk you through the process of creating a new database from a backup of another database on the same SQL Server and giving it a new name so as to avoid overwriting the existing database. The solution was to restore a copy of the company database alongside the current company database so that we could script out the necessary INSERT script to copy the data over. Fortunately these were historical tables so the likelihood of new data being inserted into these during normal business processing was very low. Thanks for your answer Now I found 'choose art' and 'refresh' button. It will allow you to choose from a list of similar movies or type in the title you require. After a major upgrade we noticed two of the Historical GL tables had been wiped out. If you want to rescrape a movie in the library, then use the 'Refresh' button in the Movie Information page as shown in the image. ![]() Specifically, the company financial database associated with Dynamics GP. I recently ran into a situation which required me to create a second copy of a very large and very important database on the production server. The issue being that if you’re trying to restore a copy of an existing database on the same server using a different name for the restored database, when not configured properly, it can actually overwrite the existing database. Yeah, the title is a bit of a mouthful but this is something that I’ve seen people struggle with constantly.
