# setprivgrp timesten MLOCK

The getprivgrp command can be used to check the privileges of a group:

$ getprivgrp timesten timesten: MLOCK

Note: On Linux and Tru64 systems, root privileges are required to use MemoryLock attribute. On Solaris systems, you must be installed as root to use MemoryLock=1 or 2.Data stores in a non-root instance of TimesTen can use settings 3 and 4 for this attribute, on Solaris systems.

Create the TimesTen registry

1.If the directory /etc/TimesTen does not already exist, create it.

# mkdir /etc/TimesTen

The disk space required for the files in this directory is less than 2k bytes.

2.Assign ownership permissions on this directory.

For example, with a TimesTen administrators group named timesten, use:

#chmod 775 /etc/TimesTen

#chgrp timesten /etc/TimesTen

If you are upgrading from a TimesTen 5.1, you must change the existing group ownership and permissions of the existing /etc/TimesTen directory on each machine that you wish to install TimesTen 7.0. In that case the instance_info file must be assigned write permissions for members of the TimesTen administrators group. For example:

#chgrp -R timesten /etc/TimesTen

#chmod 664 /etc/TimesTen/*

3.You can now install TimesTen. See the section in this chapter on installing TimesTen for your specific platform. The installer will verify the existence and permissions of /etc/TimesTen and will fail if not present and correct.

Post-installation requirements

For non-root installs, to install the TimesTen daemon start scripts in the proper system locations, the user root must run the setuproot script located in the install_dir/bin directory:

# setuproot -install
