Installation and Configuration Supplement

Configuring Communications Server for Windows NT

The following example assumes:

IBM Communications Server for Windows NT V5.01 is installed
SPMNAME is the local LU name
SPM_NAME is set to SPMNAME.

These requirements must be met:

The SPM_NAME Database Manager Configuration parameter must specify the local LU to be used by SPM. The SPM_NAME cannot represent the Control Point LU. There is no need to configure the LU 6.2 profile. DB2 will dynamically create or modify the necessary profiles. Ensure the LU represented by the SPM_NAME parameter is only used by DB2.
SPM_NAME can be set using the following command:
```
   update database manager configuration using spm_name SPMNAME
```
If your DB2 Universal Database SPM workstation will be used as a server accepting DB2 Universal Database client connections through APPC, you will need to ensure that you configure the database manager configuration parameter tpname with an appropriate value. For example:
```
   db2 update dbm cfg using tpname NYSERVER
```

Note:

If all of the following apply to your environment:

You are using the SPM workstation to connect to host or AS/400 database servers.
You are using the SPM workstation to accept connections from host or AS/400 database clients.
You have DB2 Universal Database clients accessing the SPM workstation through APPC.

then the DB2 Universal Database clients and the host or AS/400 database clients must:

Use the same transaction program name to connect to the SPM workstation.
Use the SPM_NAME LU as their partner logical unit.

Note:

It is very important that CS/NT be started before DB2. DB2 will wait for CS/NT to start before completing its own startup procedures. Therefore, if CS/NT is not started before DB2, DB2 will appear to "hang" upon starting. DB2 is actually waiting for CS/NT to start. It is strongly recommended that you register CS/NT as a Windows NT service, as outlined in the next section, to avoid this problem. CS/NT will then be started automatically before DB2 starts.
