Global File System tasks

This section contains optional post-installation tasks for the Global File System (OGFS).

Configuring User ID numbers for the Global File System

When you install a SA Core, you can set values to control the range of UID and GID numbers used by the Global File System. These values are used to provide unique user IDs for all SA users that are logged in to the OGFS. When the Web Services Data Access Engine creates a new user, it will use these values to determine the next available (unique) user ID that is within the range for the local data center.

To set values that control the range of UID and GID numbers, you must specify the following Web Services Data Access Engine parameters in the params.conf file:

  • twist.min_uid: Contains the minimum UID number that can be used. The default value is 80001.
  • twist.default_gid: Contains the group ID number that a user is assigned to restrict SA users from using certain ports. The default value is 70001.

These parameters are specified as global in the params.conf file, which means that they will be written out to the global response file (oiresponse.global). This file is generated when the Model Repository export is performed on the Primary Core server. When you follow the installation instructions and provide the global response file (oiresponse.global) as the initial response file to the Secondary Core server, SA Installer will use the specified values.

Requirements: After you make changes to these parameters, you must restart the Web Services Data Access Engine server.
