Where can you find a comparison between oracle snapshot replication and oracle streams replication?
The process of creating and managing duplicate versions of a database. Replication not only copies a database but also synchronizes a set of replicas so that changes made to one replica are reflected in all the others. The beauty of replication is that it enables many users to work with their own local copy of a database but have the database updated as if they were working on a single, centralized database. For database applications where users are geographically widely distributed, replication is often the most efficient method of database access.

What is replication ID?
A replication ID is a unique identifier used in database replication to track changes made to data across different database instances. It helps in ensuring data consistency and integrity by allowing the replication process to record and synchronize changes accurately between databases.
What is the Oracle Replication Survival Guide about?
The Oracle Replication Survival Guide authored by Martin Zahn, is a programming guide. It was written to help programmers using the database management system developed by the Oracle software company. Or more specifically, to use the replication functions of named database system.
What technology is used for replication?
There are 4 parts of technology that are used to replication. The 4 levels are storage, database, record bases and statement based.
How are replication errors corrected in a database system?
Replication errors in a database system are corrected through techniques such as data validation, error detection mechanisms, and data reconciliation processes. These methods help identify discrepancies between replicated data sets and ensure that the database remains consistent and accurate.
What is the difference between outbound and inbound replication?
Outbound replication is when a domain controller transmits replication information to other domain controllers on a network andInbound replication is when a domain controller receives updates to the Active Directory database from other domain controllers on the network.
What is the differ between Replica and Archive in Lotus Notes?
In Notes, you can go to Help, then Help Topics, then search for information like this. Here's what Notes Help says: A replica is a duplicate of a database with the same replication ID number as the original database. Notes lets you create a local (offline) replica of any database you use. Through replication, Notes can keep a local replica identical with the database on the server, so you make changes once, but they appear in both places. Replication is the process of making replicas identical. Notes uses the replica ID number to locate and replicate all replicas of a database. A database copy (created by choosing File - Database - New Copy) does not have the same ID number as its original database, and doesn't replicate. A copy of a database file created through the operating system is a replica and does have the same ID number as the original database. Replication is a great tool to have when you're away from your office network, because working in a local replica is much faster than making the same changes over a dialup telephone connection. Replication also lets users on various networks in a variety of (physical) locations share the most current version of information in a database. An archive is a copy of a database you can create to store information no longer in use. Like a replica, an archive contains documents and design elements from the original database, but unlike a replica, an archive never sends any changes back to the original database.
How do you copy a database of mysql in wamp server from one computer to another?
You have several options: * copy the database files from mysql/data/<database_name> to a new mysql Installation * use mysqldump utility to export the data from your database and load it into the new mysql installation * setup replication
What are the support tools?
Supported Tools are used to Maintain AD Services. used to handle replication as well. Ntdsutil.exe to make changes or administrate to AD database. replmon and repadmin to monitor and administrate replication. netdiag to monitor network.
What is the difference between Replication and Caching?
Replication is the process of propagating changes from one database to other database. Caching is the process of prefetching the frequently accessed data and storing it in close to the application. Refer www.csqlcache.wordpress.com for more info on caching
When is it useful to have replication or fragmentation of data?
Replication is useful when there are many read-only transactions at different sites wanting access to the same data. They can all execute quickly in parallel, accessing local data. But updates become difficult with replication. Fragmentation is useful if transactions on different sites tend to access different parts of the database.
