release data store using ttMigrate from the newer release, and then reconnecting all applications to the upgraded data store.

Note: The ttMigrate -r-renameoption, used to rename the owner of data store tables, cannot be used with online upgrades.

The general steps in an online upgrade include:

Disconnect all applications from the data store to be upgraded.

Shut down replication on the system being upgraded.

Back up the data store residing on the system being upgraded using the older release’s ttMigrate with the -c option.

Install the newer release of TimesTen on the system being upgraded.

Restore the replicated data store on the system being upgraded using the newer release’s ttMigrate with the -r option.

Reconnect all applications to the upgraded data store.

Restart replication on the upgraded system.

Note: After ttMigrate has been used, all autorefresh cache groups in the upgraded data store have AUTOREFRESH STATE set to OFF, no matter how it was set on the data store prior to the upgrade. Reset AUTOREFRESH STATE to ON by using the ALTER CACHE GROUP statement.

To maintain continuous availability, applications will continue to run on one copy of the data store while the upgrade is performed on the disconnected copy of the data store. TimesTen replication retains updates made to the active copy of the data store during the upgrade period and then transfers and applies the updates to the upgraded data store when replication is restarted. When the replicated updates have been completely applied, the applications may be reconnected to the upgraded data store.

This timeline illustrates the steps for performing an online upgrade while replication is running, where the upgrade system is the system on which the data store upgrade is being performed, and the active system is the system containing the data store that the application will remain connected to:

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.

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.

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.
