Oracle 11g Dba Books Free 12 BETTER

Learning your way around a new software stack is challenging enough without having to spend multiple cycles on the install process. Instead, we have packaged such stacks into pre-built Oracle VM VirtualBox appliances that you can download, install, and experience as a single unit. Just downloaded/assemble the files, import into VirtualBox (available for free), import, and go (but not for production use or redistribution)!

Viewed 1000+ timesYou Asked Please can you tell me which book or documents can i refer for getting inside knowledge application server? and Tom said...Well, I truly find that the documentation itself is under-utilized. Have you really read through that (lots of "inside knowledge" there - whatever you mean by inside knowledge)I do not have any 3rd party book recommendations, but we'll publish this and let others who read it post anything they've read and found useful.

Increasingly, the Oracle database products compete against open-source software relational and non-relational database systems such as PostgreSQL, MongoDB, Couchbase, Neo4j, ArangoDB and others. Oracle acquired Innobase, supplier of the InnoDB codebase to MySQL, in part to compete better against open source alternatives, and acquired Sun Microsystems, owner of MySQL, in 2010. Database products licensed as open-source are, by the legal terms of the Open Source Definition, free to distribute and free of royalty or other licensing fees.

Once RAM pages from inactive programs are written to disk (a page-out), the operating system can make the freed RAM memory available for another active task. Later, when the inactive program resumes execution, the RAM pages are re-loaded from the swap disk into RAM (a page-in). This reloading of RAM pages is called swapping, and swapping is very time-consuming and degrades the performance of the target program.

Usage note: For displaying RAM on Linux with the free command, note that the *second* data line ("-/+ buffers/cache") is the important one. Many people get confused by Linux using all "free" RAM for buffers, so the first line looks like the server is out of RAM.

Once we know the total available RAM memory, we have to subtract 20 percent from this value for MS-Windows overhead. Even in an idle state, Windows services use RAM resources, and we must subtract 20% to get the real free RAM on an idle server.

Note: When running queries for used space and free space in a tablespace, segments that have moved to the recyclebin will not be listed as normal table/index segments consuming used space, but will reduce the free space. So be aware of the size of the recyclebin when generating space usage reports for the database.

Although this is enabled by default, if the parameter recyclebin is set to OFF at the instance level, dropped tables are not retained in the recycle bin. Similarly, if the tablespace has low free space, older dropped tables are silently purged from the recycle bin. So it is advisable to query the recycle bin immediately after the problem is identified. Take care to ensure that a recycle bin is available before running your tests for flashback query on a dropped table or flashback table to before drop.
