Clone Wars<\/span><\/span><\/h2>\n

When we\u2019re hearing \u201eClone\u201c, most people will associate it with Star Wars the Clone Wars \u2026 something like that, The main idea behind the clones was that they are identically as possible with identical functions, that means that they have the same power, strength and what else.<\/p>\n

When we think about cloning databases, it\u2019s not really different. Target is to create a copy of the production environment which is preferably as much identical as we can get it, for testing and development purposes. In most cases it will not stop with only one copy. Over the time different requirements need different copies and more and more copies have to be provided. At the end it comes to our \u201eClone War\u201c between the tasks that a DBA has to accomplish and the modest requirements of the developers.<\/p>\n

<\/p>\n

In this blog series I will shortly describe different methods for cloning to give then an example for cloning with CloneDB feature for Oracle 11gR2 databases, snapshot copy for our new 12c Multitenant database and at the an extremely fancy high-end solution by a third-party developer called Delphix.<\/p>\n
