Caché Installation Directory
Throughout the Caché documentation, the directory in which a Caché instance is installed is referred to as install-dir
. This directory varies by platform, installation type, and user choice, as shown in the following table:
On Windows, OpenVMS, UNIX®, and Linux systems, you must select either 8-bit or Unicode support for your installation:
The software handles characters in an 8-bit format.
The software handles characters in the Unicode (16-bit) format. Select Unicode if your application uses languages that store data in a Unicode format, such as Japanese.
InterSystems recommends 8-bit character support for locales based upon the Latin-1 character set, ISO 88591. Use Unicode if the base character set for your locale is not Latin-1, or if you anticipate handling data from locales based upon a different character set. If you use an 8-bit version of Caché, your data is not portable to 8-bit locales based on a different character set.
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.
If you are installing Ensemble, you must select Unicode
