Review this topic to learn about open database connections in Toad.
For information about switching the current connection in Toad, see Switching Connections in Toad.
In Toad, an open connection in the Connection/Navigation Manager represents one or more actual connections to the database. When you open a database connection in Toad:
Toad also creates a separate database connection for each Editor (the first time you execute a statement) and for each Data tab in the Database Explorer (the first time you select the tab and query data).
The connection associated with the window (or tab) remains open until you close the window. If a window has an associated connection, but a statement is not currently executing, the connection is in an inactive state.
To view information for an open connection
To view the number of actual database connections that exist for a Toad connection, including the number of active connections, place the cursor over the connection in the Connection/Navigation Manager pane or in the connection drop-down list.
To use the Background Processes pane
To cancel statement execution, use the Background Processes pane.
Note: It is recommended that you cancel only your own processes, because terminating Toad activities could cause unexpected behavior.
You can instruct Toad to share an open connection among windows. In this way, the Editor windows and Data tabs can share the same connection when the connection is inactive.
To share a database connection among windows in Toad
Clear the checkbox for the Use individual connection for each open editor option.
When this option is not selected, Toad attempts to use a single connection for any new windows or query execution. For example, if you share a database connection, you can execute a query in the Editor, execute another query in a new Editor, and then select the Data tab from the same connection.
If the single connection is in use when Toad attempts to execute it, the following occurs:
Note: Although you can share a database connection, any commits apply to the selected window only.
Although this connection uses the ODBC driver, it is easier and faster to connect using this method. See Troubleshoot Access Issues for more information about troubleshooting connection issues.
Notes:
The Toad Sample Database and established connection that comes pre-loaded in Toad for SAP Solutions is an Access database. The connection information for this database is:
Database file = C:\Program Files\Quest Software\ToadInstallDirectory\Plugins\Odbc\Sample Database\Quest_Stage.mdb
Additional sample files for this database are available in the Project Manager.
To create an Access connection
Click on the toolbar (ALT+F+N).
Select Access from the Group list box.
Review the following for additional information:
Database file |
Select the database to use when connecting. |
MDW file |
Select the MDW file that is linked to the database. |
Password |
Enter the password to use when connecting. Tip: After connecting, you can set a master password to further secure your connection in Tools | Options| Environment | Security. |
Category |
Select or create a category if you want to color code Editor tabs for a specific connection. This can help differentiate between development and production databases. You can also set an option to color code the Object Explorer pane and object editor windows (Create, Alter, Drop, etc.). Click here to view a video of this feature. |
Click Connect to connect immediately while saving the connection information. Optionally, click Save to save the connection without connecting.
Consideration/Limitation | Description |
---|---|
Microsoft Access 2016 64-bit Office 365 64-bit |
To successfully create a connection to an Access database using Microsoft Access 2016 64-bit, the Microsoft Access Database Engine is required and might not have been included in the Access installation. In addition, the architecture (bitness) of the engine must match the bitness of Toad. If using 64-bit Toad, the 64-bit version of Microsoft Access Database Engine is required. If using 32-bit Toad, the 32-bit version of Microsoft Access Database Engine is required.

Tip: Connections are stored in the connections.xml file and can be found by clicking the Application Data Directory link in Help | About.
Toad allows you to connect to SAP® Business Objects through the Query as a Web Service (QaaWS) component to view and query data in QaaWS Queries.
See also, About Business Objects.
Note: This feature is available in the Toad for SAP Solutions Professional Edition only.
To create a Business Objects connection
Enter the connection information in the Create New Connection dialog. Review the following for additional information:
URL |
Enter the Business Objects URL to which you want to connect. This is the URL to the Query as a Web Service component of the Business Objects installation. See Important Information about Business Objects Connections for more information. Note: The URL should be in the following format: http://<server>:<port>/dswsbobje/qaawsservices |
Password |
Enter the password to use when connecting. Tip: After connecting, you can set a master password to further secure your connection in Tools | Options| Environment | Security. |
Category | (Optional) Select an existing category or create a new one. |
Note: In NoSQL and Business Intelligence connections, Toad automatically saves the password in the connections.xml file as obfuscated text, as well as in Toad. To add additional password security, use Toad's Master Password feature. |
Click Connect to connect immediately while saving the connection information. Optionally, click Save to save the connection without connecting.
Upon creating an initial connection, Toad automatically maps the data source objects. This process runs in the background, and until it is finished, you may experience a delay when attempting to access these objects.
To create a Business Objects connection in Toad, you must connect to the Query as a Web Service component in Business Objects. The connection URL should have the format:
http://<server>:<port>/dswsbobje/qaawsservices
Where <server> corresponds to your web server address, and <port> corresponds to the port where you set up in your web server. (dswsbobje is the default name of the Query as a Web Service web application.)
An example URL is http://server01:8080/dswsbobje/qaawsservices.
For more information about the Business Objects component, Query as a Web Service, see the documentation at http://help.sap.com/businessobject/product_guides/xir2PP/en/qaaws.pdf.
Tips:
Setting up connections to the DB2 for LUW databases and DB2 for z/OS subsystems that Toad will manage requires two main steps.
Step 1. Configure DB2 client connections - Before you can create a connection profile, each of the databases or subsystems must be cataloged on the DB2 client. This topic helps you with that process.
Step 2. Create connection profiles - Step 2 involves creating Toad connection profiles for the cataloged DB2 databases or subsystems. Each profile contains the information that Toad needs to connect to the system, such as the user ID and password, DB2 registry settings, and the default schema. See Create Toad Connection Profiles for DB2 for more information.
Use one of the following methods to catalog each of the databases or subsystems on the DB2 client.
Use this method to transfer a catalog from another DB2 client on your machine to your default DB2 client.
To transfer a catalog any time after initial setup
In the Connection Manager, click in the toolbar.
Note: If the Client Configuration Wizard opens, Toad found only one DB2 client installed.
From the DB2 Client list, select the name of the DB2 client whose catalog you want to transfer to your default DB2 client.
This list contains all current previously installed DB2 clients on your computer, including the default DB2 client instance and any Toad DB2 client installations.
To import an exported catalog profile
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list to open the Client Configuration wizard.
On the Welcome page, select Import Profile.
Click Next.
Click in the Profile name field to browse for and select the exported profile you want to import. When you select the profile, its contents display in the text pane.
Complete the wizard.
Once you close the wizard, the Database alias drop-down list in the Connections window includes all the DB2 databases and subsystems whose catalog entries you imported.
Note: DB2 does not automatically export catalog entries for the local DB2 instance and its databases on the computer from which the export is run (unless these entries already exist in the catalog). Therefore, the profile you are importing might not include these node entries. To add the missing entries to your DB2 client catalog, you must manually catalog the databases. If these databases are local to your computer, catalog them as remote databases. See Manually catalog DB2 for LUW databases for more information.
Proceed to catalog entries as needed. See Create Toad Connection Profiles for DB2 for more information.
To manually catalog a DB2 for LUW database
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list to open the Client Configuration wizard. The Welcome page displays, showing the DB2 client's existing catalog configuration in a tree view.
If the host and node names for the database you want to configure are listed in the tree, select them. These selections pre-fill certain fields required later in the wizard process. If these names are not listed, you must provide the necessary host and node information later in the wizard.
Click Add Catalog Entry.
Review the following for additional information:
Add a Host |
Description |
Operating system |
Select the operating system for the server on which the DB2 for LUW instance containing the DB2 database you are cataloging resides. For a list of supported server platforms, see the release notes. |

Enter the TCP/IP address or the system name for the server on which the DB2 database resides. |
Port number |
Enter the port number for the server on which the DB2 database resides. |
Security type |
Select a secure protocol to handle TCP traffic for this connection. |
Specify an Instance |
Description |
Node name |
Enter a user-defined name for the DB2 instance containing the database you are cataloging. If you selected the node name from the tree on the Welcome page, this information is pre-filled (but you can update it as needed). |
Instance name |
Enter the real name of the DB2 instance. |
Comment |
Enter a descriptive comment for the instance, if needed. |
Add a Database |

Enter the service account name for server's service where the database resides. Note: This option is available only when Kerberos is selected as the authentication method. |
Complete the wizard.
The Database alias drop-down list in the Connections window shows the alias for the newly cataloged database. To complete the Toad connection setup, you must create a Toad connection profile for the database. See Create Toad Connection Profiles for DB2 for more information.
Note: If you connect directly to a DB2 for z/OS subsystem, you cannot take advantage of Sysplex. If you want to use Sysplex, catalog an entry to a DB2 Connect gateway instead. See Manually catalog DB2 Connect gateways for more information.
To manually catalog a DB2 for z/OS subsystem
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list to open the Client Configuration wizard. The Welcome page displays, showing the DB2 client's existing catalog configuration in a tree view.
Click Add Catalog Entry.
Review the following for additional information:
Add a Host | Description |
Operating system |
Select z/OS for the server operating system. |
Host name |
Enter the TCP/IP address or the system name for the server on which the DB2 subsystem resides. |
Port number |
Enter the port number of the service for the DB2 subsystem. |
Enable SOCKS security |
Select this checkbox to enable the SOCKS secure protocol to handle TCP traffic for this connection. SOCKS adds an authentication mechanism for additional security. |
Add a DB2 Subsystem |
Description |
Location name |
Enter the location name of the DB2 subsystem as defined during the DB2 installation. |
Database alias |
Enter a unique, user-defined alias to identify the DB2 subsystem on your system. You can use the same name you used in the previous Location name field, as long as it does not already exist in the list aliases in the DB2 client. |
Complete the wizard. A message informs you whether the entry was added successfully.
The Database alias drop-down list in the Connections window shows the alias for the newly cataloged subsystem. To complete the Toad connection setup, create a Toad connection profile for the database. See Create Toad Connection Profiles for DB2 for more information.
In order to connect to a DB2 for z/OS subsystem, you need to catalog two entries. First, you need to catalog the DB2 subsystem on the DB2 Connect gateway. During this process, you define an alias for the DB2 subsystem. Second, you need to catalog this DB2 subsystem alias in Toad. The procedure below describes both cataloging events.
To manually catalog an entry to a DB2 Connect gateway
Catalog the DB2 subsystem on the DB2 Connect gateway. See the IBM DB2 for z/OS documentation for more information.
In the Connections (or Create New Connection) window in Toad, click beside the Database alias drop-down list to open the Client Configuration wizard.
Click Add Catalog Entry.
Review the following for additional information:
Add a Host |
Description |
Operating system |
Select the operating system for the server on which the DB2 Connect gateway resides. |
Host name |
Enter the TCP/IP address or the system name for the server on which the DB2 Connect gateway resides. |

Select the authentication method that matches the method specified for the DB2 subsystem on the DB2 Connect gateway. |
Complete the wizard.
The Database alias drop-down list in the Connections window shows the name for the newly cataloged DB2 subsystem. To complete the Toad connection setup, you must create a Toad connection profile for the subsystem. See Create Toad Connection Profiles for DB2 for more information.
Note: Toad for DB2 supports LDAP connections. See Configure DB2 LDAP Support for more information.
Additionally, Toad provides functionality to perform the following maintenance on the catalog you set up for the current DB2 client:
To edit a DB2 catalog entry
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list to open the Client Configuration wizard.
In the catalog configuration tree for the DB2 client, select the catalog entry for the DB2 database or subsystem that you want to edit.
Click Edit Catalog Entry.
On the Edit Catalog Entry page, update the catalog properties as needed. For a description of the catalog properties, see the following links:
Click Next to open the Catalog Script Review window.
Review and modify the script in the preview pane as needed.
Click Finish. A message window displays, informing you whether the updates to the catalog entry completed successfully.
To remove a DB2 catalog entry
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list to open the Client Configuration wizard.
In the catalog configuration tree for the DB2 client, expand one or more nodes, and select the catalog entries that you want to remove. (Press CTRL+click to select multiple entries.)
Note: You can remove a node by selecting all database entries for that node.
Click Remove Catalog Entry.
On the Catalog Script Review page, modify the script in the preview pane as needed.
Click Finish. A message window displays, informing you whether the removals completed successfully.
Toad for SAP Solutions provides functionality to export your current DB2 client catalog to a file, called an export profile. You can then import this profile to set up the catalog for another DB2 client.
To create the export profile containing the current DB2 client catalog, Toad executes the DB2 Connectivity Configuration Export Tool command db2cfexp. If you want to export the catalog of a remote or local DB2 client (other than your current DB2 client), you must manually execute this command. For more information, see the following IBM documentation: http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/
com.ibm.db2.udb.doc/core/r0002442.htm.
To export the DB2 client catalog
In the Connections (or Create New Connection) window, click beside the Database alias drop-down list.
Click Export Profile in the Welcome window of the Client Configuration wizard. (You might need to click this button.)
Click Next.
Click in the Profile name field to browse for and select the path for the profile in which to export the current DB2 client catalog.
Select the type of profile you want to create:
Maintain to create a profile that contains only database or node information required for updating other instances
For more information about these profile types, see the IBM documentation (as cited previously) describing the db2cfexp command.
Complete the wizard. A message window displays, informing you whether the export completed successfully.
Note: DB2 does not automatically export catalog entries for the local DB2 instance and its databases installed on your computer unless these entries already exist in the catalog you are exporting. If you later import the export catalog to a DB2 client, you must manually catalog the missing local-node databases as remote databases. See Manually catalog DB2 for LUW databases for more information.
After you have set up the catalog on the current DB2 client, you can proceed to the second phase of the Toad connection setup. This phase involves creating Toad connection profiles for the cataloged DB2 databases or subsystems. See Create Toad Connection Profiles for DB2 for more information.
