the steps outlined in “Moving between 32-bit and 64-bit data stores” on page 101.

If you need to upgrade two or more data stores that are replicating to each other, you must perform a few extra steps in order to ensure that replication will continue to operate during and after the upgrade. For example, to migrate two replicating data stores, master1 on host machine masterhost and subscriber1 on host machine subscriberhost, from TimesTen release 5.1 to TimesTen release 7.0, perform the following steps:

1.Configure the replication scheme on both data stores to use static TCP/ IP ports for replication. This is necessary because the intermediate result of these steps is that replication occurs between two different versions of TimesTen, and each version will not necessarily know how to find the main daemon of the other in order to have the replication ports assigned dynamically. See "Dynamic vs. static port assignments" in the TimesTen to TimesTen Replication Guide for more information.

2.On the machine masterhost, use the 5.1 release’s ttAdmin utility to stop the replication daemon on the data store:

ttAdmin -repStop master1

3.Next, use the 5.1 release’s ttMigrate utility with the -coption to back up data store master1 to a binary file:

ttMigrate -c DSN=master1 master1.bak

4.Use the 5.1 release’s ttDestroy utility to destroy data store master1, where the data store’s files are located in the directory data_store_path:

ttDestroy /data_store_path/master1

5.Use the 7.0 release’s ttMigrate utility with the -roption to restore data store master1 from the binary file. Restoring the data store automatically upgrades it from release 5.1 to release 7.0. If you are restoring a very large data store, you should use the -Coption to tell ttMigrate to perform a checkpoint operation on the data store periodically. This saves time if the restore fails at some point before the operation has been completed. For more information, see "Checkpoints" in the Oracle TimesTen In-Memory Database Operations Guide.

ttMigrate -r -C 20 DSN=master1 master1.bak

6.Use the 7.0 release’s ttAdmin utility to start the replication daemon: ttAdmin -repStart master1

Replication is now occurring between the data store master1 on release 7.0 and the data store subscriber1 on release 5.1.

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.
