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:

Another notable characteristic of the B31679-01 is its precision-engineered tonearm. The tonearm is designed for optimal tracking, ensuring that the stylus maintains contact with the record groove, capturing every nuance of the music. By minimizing tracking error and optimizing weight distribution, the tonearm enhances overall soundstage and detail, allowing audiophiles to rediscover their vinyl collection with newfound appreciation.

In terms of motor technology, the Oracle B31679-01 features a high-torque, low-noise motor that provides reliable and consistent speed. This is crucial for vinyl playback, as variations in speed can lead to pitch inaccuracies and a less enjoyable listening experience. The motor's design is engineered to operate quietly, ensuring that no unwanted noise enters the audio signal.

The Oracle B31679-01 also stands out with its customizable features, allowing users to tailor their experience to their personal taste. From cartridge compatibility to adjustable settings, the turntable accommodates a wide range of preferences, making it a versatile choice for both casual listeners and serious audiophiles.

In summary, the Oracle B31679-01 combines advanced engineering, premium materials, and innovative technologies to create a turntable that excels in sound quality and performance.
