Large data stores

3.Scroll down the list of parameters to semmns and change its value to a minimum of 4096 or greater.

4.For HP-UX 11i systems, also scroll down the list of parameters to shmmax and change its value to a maximum of 0x40000000.

Note: The value 0x240000000 (a 24 followed by seven zeroes) indicates that the largest shared memory segment that can be created is 1024 MB. The size of the shared memory segment required for a shared data store is larger than the requested data store size. Set this value high enough to support the largest shared memory segment needed.

5.Recompile the kernel. Choose Create a New Kernel from the Actions menu.

6.Reboot the system.

On 64-bit HP-UX systems, if you expect to have data stores that are larger than 2GB, you must enable large files. By default, HP-UX supports files that are no greater than 2GB in size.

To enable large files, create the filesystems using newfs with the -o largefiles option. Use the command:

%/usr/sbin/fsadm -F hfs -o largefiles device_name

For example:

%/usr/sbin/fsadm -F hfs -o largefiles \ /dev/vg02/rlvol1

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:

For HP-UX 11i, 11.23 (11iv2)

#/usr/bin/ndd -set /dev/tcp tcp_xmit_hiwater_lfp 524288

#/usr/bin/ndd -set /dev/tcp tcp_recv_hiwater_lfp 524288

#/usr/bin/ndd -set /dev/tcp tcp_xmit_hiwater_lnp 524288

#/usr/bin/ndd -set /dev/tcp tcp_recv_hiwater_lnp 524288

#/usr/bin/ndd -set /dev/tcp tcp_xmit_hiwater_max 524288

#/usr/bin/ndd -set /dev/tcp tcp_recv_hiwater_max 524288

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.
