To increase the maximum data segment (malloc space) a process may use, change the kernel values per_proc_data_size and

max_per_proc_data_size

For example, to change all of these values to 10GB:

1.Create a text file, kernelparams, that contains the following:

per_proc_address_space = 10737418240 max_per_proc_address_space = 10737418240 per_proc_data_size = 10737418240 max_per_proc_data_size = 10737418240

2.Log in as root and run the command:

#sysconfigdb -m -f kernelparams proc

3.You may need to reboot the system after you have made these changes. Alternatively, you can run the command:

#sysconfig -q proc

4.To view the value of the proc kernel subsystem, run the command:

% sysconfig -r subsys ttr=value

Shared memory IPC client connections

Replication

On Tru64 UNIX, to have more than 6 ShmIpc-enabled Client DSN connections per process, you must make changes to the SHMSEG kernel parameter. Kernel parameters can be changed with either the dxkerneltuner interface or the sysconfigdb command.

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:

#sysconfig -r inet tcp_recvspace=524288

#sysconfig -r inet tcp_sendspace=524288

Default installation directories

The TimesTen default installation directories for release 7.0 are:

•On Windows, C:\TimesTen\tt70

•On HP-UX, Solaris and Linux, /opt/TimesTen/tt70

•On AIX, /usr/lpp/TimesTen/tt70

TimesTen creates temporary files when large amounts of space in a data store are freed by a transaction. In addition, other TimesTen operations, such as ttRepAdmin -duplicateoperations and large deletes, use the temporary directory when copying files.

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.
