Installing Updates

Updates to Reality are made available on the NEC Reality Support webpage in the Latest Product Updates section. These are normally supplied as a service pack containing the latest recommended updates.

To download the latest service pack, on the V15.4 support page tab click the pack for UNIX/Linux platforms and save the file.

Before downloading, please read the documents Description of Recommended Updates and Installation Info File for details of the contents of the pack and any additional configuration that might be necessary.

Other support information is available on the NEC Reality website.

Procedure

1. Download the latest service pack from the Reality website to your UNIX system.

   It is recommended that you create an updates subdirectory in the realman user's home directory and save the update there.

2. Uncompress the downloaded file:

   • On Solaris and AIX, use the uncompress utility.

   • On Linux, use the gzip utility with the -d option.

3. Extract the individual updates from the resulting .tar file with the following command:

   tar -xvf fileName

4. Ensure that no users are logged into Reality. If necessary use the LOGOFF or LOGOFF-ALL command.

5. Login to UNIX as root.

6. Execute the command:

   $REALROOT/bin/killreal

   to shut down the Reality daemons.

7. Switch UNIX user-id to realman.

8. Run the install_fix command as follows:

   install_fix -a updatesDirectory

   where updatesDirectory is the path to the directory containing the downloaded updates.

   For example, if you have extracted the service pack to the directory /usr/realman/updates, when run from the realman user's home directory the command would be:

   install_fix -a updates

   Note

   If you only want to install a single update, run install_fix without the -a option and specify the file containing the required update. For example, for update V15.1.0.0001 saved in the directory /usr/realman/updates the command would be:

   install_fix updates/V.0.0001.tar

9. install_fix will ask you for your name or initials. Once you have supplied this information, the process displays a description of each update to be installed and asks you to confirm installation.

   Note

   • You can suppress the confirmation prompts by running install_fix with the -y option.

   • If the process detects that the current version of the update is already loaded, a message is displayed and the update is not installed.

   If necessary, the installation process then rebuilds Reality and/or informs you that you should logon to each database to complete the installation.

10. Log into UNIX as root and run the command:

    $REALROOT/bin/realstart

    to restart the Reality daemons.

11. If you were informed that you need to log onto each database to complete the operation, log on to each database as the database owner and ensure that you are logged on to the SYSMAN account. Then from TCL run:

    DBUPDATE 

    Follow the on-screen prompts.
