You can use Database Info activity to specify the Server URL (JDBC URL), Username and Password to access the database. Server URL points to a specific database on a specified database server. There is no standard for Server URL. Every JDBC driver uses a slightly different syntax. For example, a Server URL for a MySQL database using the com.mysql.jdbc driver might look like this:

jdbc:mysql://localhost/databaseName

Database Info uses database driver to connect to the specified Database Server.

Prerequisites

Ensure that you have created a Database Driver activity before creating Database Info Activity.

Steps to create Database Info

Go to Develop > Services > Connector > Database Info.
Click Create New.
On the New Database Info window, provide the name and description of the database Info in the Name and Description text boxes.
Select an existing JDBC database driver activity from the Select JDBC Driver drop-down list.
To use a new JDBC database driver activity, click Create New.

For information on how to create a database driver activity, refer to Creating Database Driver.
Click here to know the Server URL Pattern of Business Application Connectors.
Enter the Server URL. Click Help displayed adjacent to the Server URL text box to get help in defining the Server URL.

For example, for database format SQL-JTDS, the URL format is- jdbc:jtds:sqlserver://<databaseServerName>:<port>/<databaseName>.
Encryption Using Vault
To encrypt the confidential information, for example, databaseName using Vault, first create a vault. Now instead of writing the database name in plain text, write the aliasName and the key, in the following format:

{Vault.aliasName.key}

where,
- Following an opening curly parentheses, 'Vault' is a keyword (V in 'Vault' is UPPERCASE).
- aliasName is the Vault Alias, where the parameter, which stores the database name, is defined.
- key is the parameter which stores the database name.
- Finally closed by a closing curly parentheses.
- A period is used as a separator between Vault and aliasName; and aliasName and key.
So for database format SQL-JTDS, the URL format will be- jdbc:jtds:sqlserver://<databaseServerName>:<port>/{Vault.aliasName.key}
For example, jdbc:jtds:sqlserver://SERVERNAME:1443/{Vault.safe.db_name}
Enter the required parameters and click Save to save the Database Driver activity and return to the Create Database Info screen.
Enter the username of the database server in the User text box.
Enter the password for the username of the database in the Password and Confirm Password text boxes.
Click Test Database Connection to verify the connection between Adeptia Suite and database.
Enter the name of the schema in the Select Schema Name or click Browse Schema to browse the schema on the database whose connection you have just created.
Select Enable Connection Pooling check box to enable database connection pooling.
Enter the maximum number of connections in the Maximum Connections text box that you want to keep in your connection pool at any time, default is 10.

If you enter 0 in the Maximum Connections text box then the activity will keep an unlimited number of connections in the connection pool.
Enter the minimum number of connections in the Minimum Connections text box that you want to keep in your connection pool at any time, default is 3.
Enter the time in the Maximum Idle Time (seconds) text box. This field allows you to keep an ideal connection in the connection pool as per the time specified, default is 10.
Enter the time, in milliseconds, in the Maximum Wait Time When Exhausted (milliseconds) text box that you want the client to wait for a connection to be checked-in or acquired when the pool is exhausted.

If you enter 0 in the Maximum Wait Time When Exhausted (milliseconds) field then the client will wait indefinitely.
Click Save.
- If you edit any Database Info activity while it is being used at run-time then it would re-initialize the connection pool.
- Apart from the four connection pooling settings that are visible on the Create New Database Info screen, you can change a lot of other settings of database connection pooling in the c3p0.properties file which you can find at .../<Adeptia Suite Installation folder>/AdeptiaServer/ServerKernel/etc.
- You can also configure the c3p0.properties file for a particular Database Info activity. For this you can make a copy of c3p0.properties file and append the activity ID of the database info activity. For example, c3p0_<activityID>.properties.
  
  Here <activityID> is the 30 digit ID of the Database Info activity.
  When you use this file then at the time of execution, the connection pool properties defined in this file are used instead of the one defined in c3p0.properties file.
