A. The operating system user <sid>adm must be able to log on to the secondary database.
B. The R/3 table DBCON must be maintained.
C. The correct database library 'dboraslib.<ext>' must exist in the kernel directory. Connect to SQL Server database Prerequisite: At least one Windows application server must be available on the R/3 system and the DBSL dynamic library (DLL) dbmssslib.dll must be installed on this server. This dll can be downloaded from the SAP Service Marketplace.
A. 访问MSSQL的配置示例(参见SAP Notes 178949)
CON_NAME: <my_conn_name>DBMS: MSSUSER_NAME: <db_user>PASSWORD: <password>CON_ENV: MSSQL_SERVER=<server_name> MSSQL_DBNAME=<db_name>
db_user could be sapr3 for example if the server is running R/3. The password field may be blocked from view by asterisks in sm30. USER_NAME can be left blank in order to use integrated security (4.6d kernel and later). In that case make sure that the OS User running R/3 has the required privilege on the remote server. A dummy password must be entered in sm30, it will not be used when the user name is blank.
Specifying the server name
The server name is simply the name of the SQL Server or named instance i.e. the hostname (for a default instance), or <host>/<instname>Starting with release 6.40 however there are some special considerations that should be taken into account. When running with kernel release 6.40 or later, the R/3 system will prepend a protocol specifier to the server name. Example: 1. For a server running on the same server: np:<servername> 2. For a remote server: tcp:<servername>This forces the connection to be made with a named pipes and tcp/ip protocols respectively.When specifying the server name you can override this by setting your own protocol (tcp: or np:), or you can make R/3 avoid setting any prefix by using simply :<servername> - a colon in front of the server name.
Connection name logical name of the connection
User name Oracle users
DB password password for the above-mentioned Oracle user
Conn.info TNS alias
Permanent Usually should not be set for a secondary connection.
