Server pre-installation tasks
Complete the following server tasks before installation.
Connect to the database
Create OS user accounts
Before you install, create an OS user account and associated group for the Dimensions System Administrator (the person responsible for all database and maintenance operations). Normally this is dmsys, however, an alternative user account can be assigned. During installation you are prompted for this account and its password.
Note:
-
The Dimensions System Administrator is the UNIX user (by default dmsys) that owns the Dimensions CM files and starts the appserver and libservever processes. By default, Dimensions CM works with a dmsys user without administration privileges. However, dmsys can also be a member of the admin group. This may be necessary in certain logging scenarios, for example, to obtain command audit logging that has been set in the dm.cfg file.
-
For Oracle Enterprise, the primary group-id for dmsys must be the same group-id as the Oracle instance owner's group-id (for example, dba). The user dmsys must also be a secondary group member of the group dmtool.
Depending on which process model you install you may set up additional OS user account names for the process model. Choosing a Process Model.
During installation choose one of these process models:
-
(Default) Typical, Stream Development
Demonstrates stream development features. This model follows a "copy, modify, merge" methodology for managing modern, parallel development projects.
-
Typical, Non-Stream Development
Demonstrates non-stream development features. This model follows a "lock, modify, unlock" methodology for managing more traditional development projects.
-
Custom
This process model has no pre-defined roles and no associated sample product. It is intended for use by:
-
Experienced users to facilitate definition of a new model, without having to delete definitions from a pre-loaded process model.
-
Existing users who have created their own process model export file to import when creating the base database. This model is also available by choosing the import option from the dmdba crdb function. See the Administration Guide for details.
-
If you are upgrading the installer also upgrades your process model.
Important: Before importing a process model, check with Support that it is valid.
Use TCP/IP ports
Web Tools Port
During server installation, the installer assigns TCP/IP port 8080 to the various web tools. Verify that this port is not already being used by other software. Some software is hard coded to port 8080 and cannot be reassigned. If port 8080 is not available, specify an alternative port during installation.
Important:If a server is behind a firewall the port must allow traffic in both directions.
Dimensions CM Listener Port
By default the Dimensions CM listener port is set to 671. You set this in the /etc/services file as described in Security on Red Hat Enterprise.
Secure Sockets Layer Ports
The web tools also configures two Secure Sockets Layer (SSL) ports:
-
8443: a general port for https/SSL connections and the sample Dimensions CM SSL certificate.
-
8543: a port for https/SSL connections that are used to perform smart card authentication.
