utility. (See "ttAdmin" in Oracle TimesTen In-Memory Database API Reference Guide.) In order to unload a data store:

1.Disconnect all applications from the data store.

2.In this example, the data store original is from the previous release. The data store upgrade is in the new release. If replication has been started, pause replication on the data stores, and then stop replication on the data store that you are unloading from memory, using the commands:

ttRepAdmin -receiver -name upgrade -state pause original ttRepAdmin -receiver -name original -state pause upgrade ttAdmin -repStop upgrade

3.If the cache agent has been started for the data store, stop the cache agent with the command:

ttAdmin -cacheStop upgrade

4.Verify that the RAM policy allows the data store to be unloaded. If the RAM policy is set to manual, unload the data store using the command:

ttAdmin -ramUnload upgrade

If the RAM policy is set to always or inUse, change it to manual. If the RAM policy is inUse and a grace period is set, set the grace period to 0 or wait for the grace period to elapse.

5.Use the ttStatus utility to verify that the data store has been unloaded from memory. (See "ttStatus" in Oracle TimesTen In-Memory Database API Reference Guide.)

Moving to a new patch release of TimesTen

All applications concurrently connected to a data store must be directly linked to a TimesTen ODBC driver of the same major release. TimesTen data stores from different patch releases are structurally equivalent or identical. For example, when upgrading from release 7.0.10.0.0 to 7.0.20.0.0, you do not need to migrate your existing data stores. However, during the installation of a new major or minor release, you should disconnect your application and stop the TimesTen daemon. If you have not explicitly performed these steps, the prior release's TimesTen daemon process is stopped, effectively disconnecting all applications from the data store. While preparing for the upgrade, make sure that all data stores are unloaded from memory before upgrading TimesTen.

For a description of the procedures for unloading a data store from memory, see “Unloading a data store” on page 95.

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.
