Installation Directory
The installation directory is the directory in which an InterSystems IRIS instance is installed. Throughout the documentation, this is referred to as install-dir. Once InterSystems IRIS is installed, it is impossible to change the installation directory.
There are several restrictions to what you can specify as the install-dir. The directory must be a fully resolved physical path, containing no symbolic links. The name of the directory can only use characters in the US ASCII character set, and cannot contain a caret (^). Also, InterSystems IRIS cannot be installed into a directory that is:
-
a UNC (non-local) path.
-
at the root level of a drive (such as C:\).
-
anywhere under the \Program Files directory.
If unspecified during installation, install-dir uses a default value. This default varies by platform, installation type, and user choice, as shown in the following table:
|
Platform |
Installation Type |
Default Directory |
|---|---|---|
|
Windows |
attended | C:\InterSystems\Iris (or IrisN when multiple instances exist), unless installing user specifies otherwise. |
| unattended | C:\InterSystems\Iris (or IrisN when multiple instances exist), unless INSTALLDIR property specifies otherwise. | |
|
UNIX®, Linux, macOS |
attended | No default; installing user must specify.
Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory. |
| unattended | No default; ISC_PACKAGE_INSTALLDIR parameter required. |
