DB2 Data Links Manager Quick Beginnings

Installation Considerations and Prerequisites

Please read this information carefully before installing a DB2 Data Links DFS Client Enabler.

DCE-DFS Client Version 3.1

You must install a DCE-DFS Client Version 3.1 on any machine that will run a DFS Client Enabler. Use of the DCE slim client is not supported.

Should I use the db2setup utility or SMIT?

We strongly recommend that you use the db2setup utility if you are installing a DFS Client Enabler. The db2setup utility performs almost all setup and configuration tasks for you. If you want to install the DFS Client Enabler fileset using SMIT, you will have to set up and configure your system manually.

Operating system level

Ensure that you are running AIX Version 4.2.1, Version 4.3.1 Version 4.3.2 or Version 4.3.3. To check the level of the operating system, enter the oslevel command.

Disk space requirements

Ensure that there is at least 2 MB of free disk space in the /usr/lpp directory. To check available free disk space, enter the df -k /usr/lpp command.

Synchronize system clocks

Ensure that your system clocks are synchronized and remain synchronized. Synchronization of clocks is essential for the Data Links token expiry interval to work correctly. The token expiry interval is a database configuration parameter. To check the system time and date, enter the date command. For more information on synchronizing system clocks, refer to your AIX Administration Guide.

The following are additional installation considerations you should take into account before you begin installing DB2 Data Links DFS Client Enabler.
