Configuring the adapter consists of specifying connection and authentication information for each of the connections you want to establish.
For an ODBC interface, the server must be brought up in TCP/IP mode.
How to: Reference: |
In order to connect to an Progress database server, the adapter requires connection and authentication information. You supply this information using the SET CONNECTION_ATTRIBUTES command. You can:
You can declare connections to more than one Progress database server by including multiple SET CONNECTION_ATTRIBUTES commands. The actual connection to the Progress Server takes place when the first query that references the connection is issued. If you issue multiple SET CONNECTION_ATTRIBUTES commands:
You can configure the adapter from either the Web Console or the Data Management Console.
or
From the Data Management Console, expand the Adapters folder.
The Adapters folder opens.
The Add Adapter to Configuration pane opens.
The Progress adapter is under the SQL group folder.
The followingn list describes the connection attributes for which you can supply values. To complete the attribute declaration, click the Configure button.
Logical name used to identify this particular set of connection attributes. The default is CON01.
The data source name (DSN). There is no default data source name. You must enter a value.
Authorization ID to connect to the source.
Password associated with the authorization ID.
Select a profile from the drop-down menu to indicate the level of profile in which to store the CONNECTION_ATTRIBUTES command. The global profile, edasprof.prf, is the default.
If you wish to create a new profile, either a user profile (user.prf) or a group profile if available on your platform (using the appropriate naming convention), choose New Profile from the drop-down menu and enter a name in the Profile Name field (the extension is added automatically).
Store the connection attributes in the server profile (edasprof).
ENGINE SQLPRO SET CONNECTION_ATTRIBUTES connection DSN_name/userid,password
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Is the logical name used to identify this particular set of connection attributes.
Note that one blank space is required between connection and DSN_name.
Is the Progress Data Source Name (DSN) you wish to access. It must match an entry in the odbc.ini file.
Is the primary authorization ID by which you are known to Progress.
Is the password associated with the primary authorization ID.
The following SET CONNECTION_ATTRIBUTES command declares connection CON1 to the Progress DSN named SAMPLESERVER with an explicit user ID (MYUSER) and password (PASS). To ensure security, specify connection attributes from the Web Console, which encrypts the password before adding it to the server profile.
ENGINE SQLPRO SET CONNECTION_ATTRIBUTES CON1 SAMPLESERVER/MYUSER,PASS
The syntax for the CONNECTION_ATTRIBUTES command for this adapter has been enhanced to include a logical connection name that is designed to support the porting of applications from development to production environments. This enhanced syntax may necessitate the migration of existing CONNECTION_ATTRIBUTES commands.
The Web Console Migrate option migrates your server settings to the newer release. To access this option, select Workspace, then Configuration/Monitor from the menu bar. Right-click Migrate from the Server folder in the navigation pane, and select Configure. On the Migrate pane, type the full path of the configuration instance directory (EDACONF) and click the Migrate button. This is the recommended approach.
If you choose not to use the Migrate option, please note the following information:
For example, suppose that prior to Version 7 Release 6.1, the connection was defined as:
ENGINE SQLPRO SET CONNECTION_ATTRIBUTES DSN_A/uid,pwd
When synonyms based on objects stored in this DSN_A are created, the Access Files contains the following description:
CONNECTION=DSN_A
If you then add a new connection, you must change the connection name from the default CON01 to DSN_A and save it as DSN_A in order to reuse the existing synonym. The connection is stored in the profile as:
ENGINE SQLPRO SET CONNECTION_ATTRIBUTES DSN_A DSN_A/uid,pwd
How to: |
Once connections have been defined, the connection named in the first SET CONNECTION_ATTRIBUTES command serves as the default connection. You can override this default using the SET DEFAULT_CONNECTION command.
ENGINE SQLPRO SET DEFAULT_CONNECTION connection
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Is the connection defined in a previously issued SET CONNECTION_ATTRIBUTES command. If this name was not previously declared, the following message is issued:
FOC1671, Command out of sequence
Note:
FOC1671, Command out of sequence.
The following SET DEFAULT_CONNECTION command selects the database server named SAMPLENAME as the default database server:
ENGINE SQLPRO SET DEFAULT_CONNECTION SAMPLENAME
How to: |
The SET AUTODISCONNECT command controls the persistence of connections when using the adapter for each of the connections you want to establish.
ENGINE SQLPRO SET AUTODISCONNECT ON {FIN|COMMAND|COMMIT}
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Disconnects automatically only after the session has been terminated. FIN is the default value.
Disconnects automatically after each request. Depending on how often the event occurs, the SET AUTODISCONNECT command may result in considerable overhead. Almost all of this overhead is not related to the server. It is related to the operating system and the data source.
Disconnects automatically only after COMMIT or ROLLBACK is issued as a native SQL command.
