Right click on My Computer and select Properties. On the Default Properties tab, check the following. On the COM Security tab, check the following: a. On the Default Protocols tab, check the following: a.
Make sure that Allow Remote Clients is checked. Make sure that Allow Inbound is checked. Make sure that Allow Outbound is checked. Make sure that Enable XA transactions is checked. Make sure that the No Authentication Required radio button is selected.
After implementing the changes reboot the server for the changes to take affect. After that is all done we can now start creating a link server connection. Setting up the Provider 1.
Start the Enterprise Manager and then access the server you want to configure. Right-click the Linked Servers entry and from the shortcut menu open the folder called Providers. Uncheck all the properties except for Dynamic Prepare see figure 2. Adding Linked Servers If you want a server to be able to use distributed queries, distributed transactions, or RPCs or all three , you must configure linked server connections to other servers.
For example, if clients that access a sql server named vista make distributed queries to mysybase ASE , you'll want to configure mysybase as a linked server on vista. To add a linked server, complete the following steps:. Start Enterprise Manager and then access the server you want to configure 2. This opens the dialog box shown in Figure 3 4. In the Linked Server field, type the name of the linked server to create 5. If you're linking to a different data source, select the Other Data Source option button and then configure the data source using the input fields provided.
You can't configure unavailable fields for the selected provider. Data Source Provider Leave Blank. Server Options Collation compatible controls sort order settings. If you don't select this option, SQL Server uses the local sort order. This affects the order of result sets, and you should note it when you develop SQL Server applications or configure clients. Leave it to the default setting Blank. Data Access Set this option to enable the linked server for distributed query access. Set it to true.
RPC Set this option to enable remote procedure calls from the linked server. If you don't set this option, SQL Server interprets data from the linked server using the default collation of the local server instance. Note that only the SQL Server databases take advantage of this option. Set it to true Collation Name Set this option to assign a specific collation for queries and transactions.
Note that you must clear the Collation Compatible check box before you can set this option. Leave this blank since we want to use Collation Compatible. Connection Timeout Sets the timeout value for connections made to the remote. Leave it to the default setting. Click OK to create the linked server.
Next, you'll need to configure security settings for the linked server. Go to the security page still on Linked Server Properties. Select 'Be made using this security context'. Type a login and password that exists on the remote ASE server. Either way will work just fine. See Figure 4. In Figure6, You can now tree down the newly created link server and see all the databases and tables in each linked server. Recycling can help. Four part naming. Execute statements.
The following example executes the sysdatabases stored procedure on the remote server ASE Server nutmeg and stores the return status that indicates success or failure in retstat.
Delete statements. Insert Statements. Sybase fully supports the IRowsetChange interface on the row set opened through IOpenRowset on the table that is having data inserted into it. Declare statements. In this example we are inserting data see Fig8. Another way of writing the same statement is.
Errors: If you get error Msg this can be caused by not having the Schema updated. It can also mean there is bad connection information such as Product Name. This Error is a permission error. The user account is not on or does not have permission on the remote Operating System.
Or your local account has permission in DCOM. Engineering is working on a fix for this. I have found Security is the biggest issue when using link Server.
Again, DCOM configuration is very important, so make sure you formulizes yourself with the configuration options. Limitation First there are limitations in place on the Link Server by Microsoft. NULL constants cannot be inserted into a timestamp column through a distributed query. Explicit values cannot be inserted into identity columns in remote tables.
Sybase Engineering has made major commitments to the improvements in the drivers in several key areas: performance, link Server, SSIS and Replication. Sybase Engineering has added new feature into the driver, inserting into a table with float or nchar columns via link server, support for four part naming convention and several others.
