TimesTen Installation 37
Prerequisites for non-root installations
on UNIX systems
As discussed in Chapter 1, “Access Control,” on UNIX systems, you
can install TimesTen as a non-root user. This entire section applies to all
UNIX platforms on which TimesTen is supported, unless otherwise
indicated.
However, you may need to perform certain tasks as the user
root, both
prior to installing TimesTen and after installation. This section outlines
those tasks that must be performed as the user,
root.
Installation prerequisites for non-root installs
You must be sure that the prerequisites defined in “Installation
prerequisites” on page 25 have been met, before continuing with your
installation. Perform the pre-requisite steps for your particular platform.
The following steps are required for installations that are installed by a
non-root user, whether they use Access Control or not. These
procedures are also required for all installations that will enable Access
Control at install time.
Create the TimesTen instance
administrators group
Before installing TimesTen, you must create the instance administrators
group:
1. Log in as root.
2. Create an operating system group for the TimesTen administrators
group. Only members of this group can install TimesTen.
We suggest using the name
timesten for the group, but you can choose
any name that you prefer.
3. Add the user(s) who are installing and administering TimesTen to the
TimesTen administrators group.
When installing as a non-root user on HP-UX systems, the operating
system user running the TimesTen daemon must belong to an operating
system group that has been given the
MLOCK privilege, if you want to use
the MemoryLock feature of TimesTen.
For example, if the user is a member of a group called
timesten, then
the following command (run as
root) gives the timesten group the
MLOCK privilege:
