Replication For replication, TCP send and receive buffers should be increased to a minimum of 512KB. You may need to embed the following commands into a script that can be run at system boot time:

#/usr/sbin/ndd -set /dev/tcp tcp xmit_hiwat=524288

#/usr/sbin/ndd -set /dev/tcp tcp_recv_hiwat=524288

Tru64 UNIX

Semaphores On Tru64 UNIX systems, to view existing kernel parameter settings, log in as user root, and use the command:

# /sbin/sysconfig -q ipc

For each data store, TimesTen consumes 100 SEMMSL if the Connections attribute is set to the default value (64), and one additional SEMMSL for each estimated connection above the default.We recommend that you increase the number of semaphores:

1.Log in as user root.

2.To view the current limits, use:

% sysconfig -q ipc

This command displays all the parameters of the IPC subsystem.

3.If the broadcast_wakeup semaphore parameter exists on your system, it must be set to one:

sem_broadcast_wakeup = 1

4.Run the Tru64 UNIX dxkerneltuner:

% dxkerneltuner

5.Double-click IPC.

6.Scroll down the list of parameters and change the values of the following parameters to at least the values indicated here:

Shared memory

sem_mni = 20 sem_msl = 512 sem_opm = 100 sem_ume = 100

Note: The values in this step are the minimum number of required semaphores. You can increase these numbers as needed.

To increase the maximum address space a process may use, change the kernel values per_proc_address_space and

max_per_proc_address_space

B31679-01 specifications

Oracle Audio Technologies has long been known for its commitment to high-end audio equipment that delivers superb sound quality and innovative design. One standout product from the company is the Oracle B31679-01, a remarkable turntable that showcases their expertise in the audio domain.

The B31679-01 embodies advanced engineering principles and a passion for music reproduction. At the heart of its design is a highly rigid yet lightweight chassis that minimizes vibrations, ensuring that the audio signal remains pure and uncolored. This attention to vibration isolation is critical, as even the slightest interference can compromise the clarity and fidelity of the sound. The turntable is constructed using premium materials that enhance performance and aesthetic appeal, adding an element of sophistication to any audio setup.

One of the key features of the Oracle B31679-01 is its sophisticated suspension system. The innovative suspension technology helps decouple the turntable from external vibrations and resonances, creating a stable platform for vinyl playback. This is particularly important in environments with background noise or potential disturbances, allowing users to experience their music as intended.

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. Its focus on vibration isolation, precise tonearm design, reliable motor operation, and customization options make it a distinguished choice for those seeking an exceptional vinyl experience. Oracle Audio Technologies continues to set high standards in the audio industry, and the B31679-01 is a testament to their dedication and expertise.
