If you have a tip on installing J for a particular situation, please add it on this page.
Multiple Users
Multiple users can share a single J installation. Each user will automatically get their own <Juser> and <Juser>/temp folders in their <HOME> folder.
The simplest way to share a J installation is to do a System Install. However it is possible to share either a Custom or Standard Install too, if the following steps are taken:
- provide all users with read permissions for the <Jinstall> folder
- provide read/write permissions to the <Jinstall> folder for the user who is primarily responsible for J and updates and maintenance
- provide all users with a convenient way to run J. This will vary across platforms.
Customize Location of User folder
The default <Juser> folder is <HOME>/jxxx-user (or <HOME>/j64-602-user). Override this and the location of other folders by creating an appropriate profilex.ijs in your <Jinstall>/bin folder.
<Jinstall>/bin/profilex_template.ijs is a template for profilex.ijs and contains examples of common use scenarios. Copy <Jinstall>/bin/profilex_template.ijs to <Jinstall>/bin/profilex.ijs Study the examples in the profilex.ijs file before making changes.
For example, if you installed J in c:\j and want the <Juser> folder to be in the same folder as the install (i.e. c:\j\jxxx-user), then:
1. copy c:\j\bin\profilex_template.ijs to c:\j\bin\profilex.ijs 1. edit c:\j\bin\profilex.ijs and uncomment example 4.
NB. example 4: user in same folder as install user=. (PATHSEP_j_(i:~{.])install),userx
If your changes prevent J from starting properly, you can always delete your profilex.ijs file to restore normal functionality.
USB Memory Stick
You can copy a <Jinstall> folder to a USB memory stick for a complete and portable J installation. If you want the <Juser> folders to be on the memory stick you need to create a profilex.ijs file in the memory stick <Jinstall>/bin folder. See Customize Location of User folder for more information. You will want to edit profilex.ijs to have <Juser> within the <Jinstall> folder.
If you don't put profilex.ijs in the <Jinstall> folder on the memory stick, the J system will put the <Juser> folder in the user's <HOME> folder.
