I have multiple applications which work with one centralized Oracle database.
The applications are targeted on following platforms:
I want to know which kind of cipher I should use to make sure all my encrypted data will be readable (decrypted) for all my application
E.g. 3DES or RIJNDAEL_256 or TWOFISH256?

AES - A US Federal Government standard since 2002, AES or Advanced Encryption Standard is arguably the most widely used block cipher in the world. It has a block size of 128 bits and supports three possible key sizes - 128, 192, and 256 bits. The longer the key size, the stronger the encryption.
Transposition ciphers keep all the original bits of data in a byte but mix their order. Substitution ciphers replace specific data sequences with other data sequences. For example, one type of substitution would be to transform all bits with a value of 1 to a value of 0, and vice versa.
AES. The Advanced Encryption Standard (AES) is the algorithm trusted as the standard by the U.S. Government and numerous organizations. Although it is highly efficient in 128-bit form, AES also uses keys of 192 and 256 bits for heavy-duty encryption purposes.
You should be able to implement those ciphers on all of the target platforms you mentioned.
As for which to use, I'd suggest Rijndael (AES) since it has received a lot of attention and has a proven security track-record.

http://gpg4browsers.recurity.com/ has JS implementations for all ciphers you mentioned.
All OSes you mentioned support all of these ciphers either directly or via mcrypt.
This reduces the question to opinionizing: So here is my opinion - do NOT standardize (in the sense of hardcode) to any of those ciphers, but invest the on-time penalty to develop your apps and protocols in a way, that allows them to handshake the cipher used. This way you can trade speed for security now and are open for developments in cryptography (or cryptanalysis)
