DB2 Data Links Manager Quick Beginnings

Installing DB2 Data Links Manager on Windows NT

To install DB2 Data Links Manager:

1. Log on to the system with a user account that belongs to the Local Administrators group.
2. Shut down any programs that are running so that the setup program can update files as required.
3. Insert the CD-ROM into the drive. The auto-run feature will automatically start the setup program. If not, run setup.exe from the root directory of the CD-ROM.
4. The Launchpad window opens.
5. Click Install and respond to the setup program's prompts. Online help is available to walk you through the remaining steps. You can invoke the online help by clicking Help or pressing F1 at any time.

   You can click Cancel at any time to stop the setup program.

Actions performed by the setup program

After installation is complete, the setup program will have:

1. Created DB2 Data Links Manager program groups and items (or shortcuts).
2. Updated the Windows NT registry with the following entries:
   • DLFM_PORT=port_number, where port_number is the port number reserved for the Data Links File Manager.
   • DLFM_LOG_LEVEL=LOG_ERR
   • DB2_RR_TO_RS=ON
   • DB2_HASH_JOIN=ON
   • DLFM_INSTALL_PATH=x:\sqllib\bin, where x: is the Data Links Manager installation drive.
   • DB2INSTANCE=DLFM
   • DLFM_BACKUP_DIR_NAME=x:\dlfmbackup, where x: is the Data Links Manager backup installation drive.
3. Created and registered various services.
4. Set up the required links for the Data Links Filesystem Filter.
5. Created an instance called DLFM.
6. Created a user account for the DB2 Data Links Manager Administrator (if you did not provide your own).
7. Created a user account for use by the Data Links File Manager. By default, this user account is created with the username DLFM1 and password IBMDLFM1. Since this username and password is used for any DB2 Data Links Manager installation, this could pose a security risk to your network. We recommend that you change this password after installing DB2 Data Links Manager.

   If you change the default password for the default DLFM1 user account, you must update the registry with the new password by entering the following command:

      dlff set dlfmaccount dlfm1
   

8. Reserved the port number you specified for use by the Data Links File Manager and added an entry to the services file that is similar to the following:

      db2cDLFM     50100/tcp
   

9. Created a DB2 database, called DLFM_DB, which is used to keep track of those files that are under the control of the Data Links File Manager and used in a database where tables using DATALINK columns reside. This database was automatically backed up after it was created.
