DB2 Version 9.7 for Linux, UNIX, and Windows

Setting the location for accessing the DB2 Information Center

About this task

If you want to change the location from which the DB2 documentation in the DB2 Information Center is accessed, you must change the values for the DB2_DOCHOST and DB2_DOCPORT variables. The DB2 Information Center can be accessed from the IBM Web site (default location), an intranet server, or locally, from your own computer.

Before you begin

To access the DB2® Information Center from an intranet server, or from you own computer, you must have installed the DB2 Information Center on the appropriate computer.
To modify global-level and instance level variables:
- For Windows operating systems, you must have system administration (SYSADM) authority.
- For root installations on Linux and UNIX operating systems, you must have SYSADM authority to change registry values for an instance and root authority to change parameters in global-level registries. For non-root installations, you must be logged in as the non-root instance owner.

Procedure

Determine the appropriate values for the DB2_DOCHOST and DB2_DOCPORT variables. The values are determined by whether you want to access the DB2 Information Center from the IBM website, an intranet server, or from your own computer.

Access location	Values for DB2_DOCHOST and DB2_DOCPORT
IBM Web site (default location)	DB2_DOCHOST: Use the value publib.boulder.ibm.com/infocenter/db2luw/v9r7 DB2_DOCPORT: Not applicable.
Intranet server	DB2_DOCHOST: Use the host name of the intranet server. For example, `companyserver.companyname.com` DB2_DOCPORT: Use the port number of intranet server. For example, 51000
Local computer	Network Information Center DB2_DOCHOST: Use the host name of the local computer or the value "localhost". DB2_DOCPORT: Use the port number of the local computer. For example, 51000 Workstation version of the DB2 Information Center DB2_DOCHOST: Use the host name of the local computer or the value "localhost". DB2_DOCPORT: Use the port number of the local computer. For example, 51097

Update the DB2_DOCHOST and DB2_DOCPORT variables.
You can change the values for these variables for all instances (globally), for a particular instance, or for an individual user profile at the operating-system or environment level.

The order of precedence in which the values for these variables are used from the least to the greatest is as follows: global, instance, and environment. This order of precedence means that setting the variables at the environment level overrides any global level and instance level settings for the variables. During installation, these variables are set at the global level only.
- Set the location for accessing the DB2 Information Center at the environment level
  On Windows operating systems:
  1. Click Start > Settings > Control Panel > System.
  2. From the System Properties dialog, click the Advanced tab.
  3. To open the Environment Variables window, click the Environment Variables push button.
  4. To add or update the current values of the DB2_DOCHOST and DB2_DOCPORT variables, click the New or Edit push buttons.
  For Linux and UNIX operating systems, use the export command or add the variables to the user's profile file.
- Set the location for accessing the DB2 Information Center at the instance level using the Tools Settings notebook
  1. To open the Tools Settings notebook, click on the DB2 toolbar, and then click the Documentation tab.
  2. In the Documentation location fields, specify for this instance where to access the DB2 Information Center.
  3. To have the Documentation location values take effect, including resetting the default values, click Set and restart the center in which you are working.
- Set the location for accessing the DB2 Information Center at the global level, use the Configuration Assistant or the db2set command.
  For example:
```
db2set DB2_DOCHOST = companyserver.companyname.com
db2set DB2_DOCPORT = 51000
```
Confirm the current values of the DB2_DOCHOST and DB2_DOCPORT variables.
Issue the command db2set -all without parameters in the command line processor. The characters [g], [i], or [e] next to the output values indicate that the values are set at the global, instance, or environment levels respectively.
