Caché Installation Guide - InterSystems Documentation

Installing Caché on UNIX and Linux
CAUTION:
If you choose a Unicode installation, you cannot revert to an 8-bit version without
potential data loss. This is because an 8-bit version of Caché cannot retrieve 16-
bit character data from a database.
6. You next decide how restrictive you want the initial Caché security settings to be. Choose from
Minimal (1), Normal (2), and Locked Down (3). The default is Minimal; if you choose this, the
owner of the instance becomes root and the installation continues with the next step.
If you enter 2 or 3, the script asks for additional information:
a. Owner of the instance — Enter a user name to use as the effective user ID under which to
run Caché processes. Once Caché is installed, you cannot change the owner of the instance.
The installation process lists other accounts it creates for you. Caché assigns the password
you enter at the next prompt to each of these accounts.
b. Password for the entered user — Enter one Caché password for the user name twice to confirm
it.
Note:
Passwords entered during this procedure should not include whitespace or backslash
characters.
For a detailed explanation of these settings, see the Initial Caché Security Settings section of the
“Preparing for Caché Advanced Security” appendix of this guide.
Important:
There are additional security settings that you can only choose through a custom
install. See the Caché Custom Installation section for details.
7. At this point in the installation, you are asked which group should be allowed to start and stop
Caché. Only one group can have these privileges, and it must be a valid group on the machine.
Enter the name or group ID number of an existing group; Caché verifies that the group exists
before proceeding.
8. If the installation does not detect a cache.key file in the mgr subdirectory, it asks if you want to
enter the license key information; the default is No. You can enter the key information after the
installation.
If you choose Yes, Caché installs a key as part of the installation process. See the Updating the
License Key section of the “Managing Caché Licensing” chapter of the Caché System Administration
Guide for details about entering InterSystems Caché licensing information.
9. Next, you are asked if you want to configure the CSP Gateway to use a supported external Web
server. Answer Yes and then answer additional Web server configuration questions to configure
the CSP Gateway after the Caché installation completes.
