Abstract

Converting data for an application ported from an operating system (OS) platform of a first computer to an OS platform of a second computer. Configuration information associated with ported application including the first computer'"'"'s OS platform is stored on the second computer. The ported application executing on the second computer receives first data encoded in a first code set. The OS of the second computer receives a request to convert the first data to a second data encoded in a second code set, locates a first-code-set-to-second-code-set mapping based on at least maintained code set mappings of the OS of the first computer, and converts the first data to the second data using the located first-code-set-to-second-code-set mapping. The second data is compatible for processing on the second computer and output from converting the data on the second computer is equivalent to an output from converting the data on the first computer.

Claims

1. A method for converting character encoded data for an application that is ported from an operating system (OS) platform of a first computer to an OS platform of a second computer, the method comprising:

receiving, on a second computer, an application ported from a first computer, the first and second computers having different first and second OS platforms, respectively;

receiving by the second computer, configuration information associated with the ported application that includes information corresponding to the first OS platform;

executing, by the second OS platform, the ported application;

receiving, by the executing ported application, first character data encoded in a first code set;

receiving, by the second OS platform from the executing ported application, a request to convert the first character encoded data to a second character encoded data encoded in a second code set;

locating, by the second OS platform, a first-code-set-to-second-code-set mapping based on at least the received configuration information associated with the ported application; and

converting, by the second OS platform, the first character encoded data to the second character encoded data using the located first-code-set-to-second-code-set mapping, such that the second character encoded data is equivalent to an output resulting from converting the first character encoded data on the first OS platform.

2. The method according to claim 1, wherein locating further comprises locating the first-code-set-to-second-code-set mapping from a plurality of first-code-set-to-second-code-set mappings, each first-code-set-to-second-code-set mapping associated with a different OS platform.

3. The method according to claim 1, wherein locating further comprises locating the first-code-set-to-second-code-set mapping from a plurality of first-code-set-to-second-code-set mappings located on one or more network storage devices.

4. The method according to claim 1, wherein locating further comprises locating the first-code-set-to-second-code-set mapping from a pool of preferred code set mappings based on one or more of frequency of use and most recently used.

5. The method according to claim 2, wherein the different OS platforms include Windows®

, Linux®

, AIX®

, SOLARIS®

, and Virtual Machine®

(VM).

6. The method according to claim 1, wherein the request to convert is an invocation of an ICONV application programming interface.

7. The method according to claim 3,

wherein the second computer includes a plurality of first-code-set-to-second-code-set mappings comprising:

one or more first-code-set-to-second-code-set mappings associated with the OS platform of the first computer; and

one or more first-code-set-to-second-code-set mappings associated with the OS platform of the second computer; and

wherein locating the first-code-set-to-second-code-set mapping from a plurality of first-code-set-to-second-code-set mappings located on one or more network storage devices further comprises adding the located first-code-set-to-second-code-set mapping to the plurality of first-code-set-to-second-code-set mappings included in the second computer.

8. The method according to claim 1, wherein locating further comprises locating a default first-code-set-to-second-code-set mapping if a first-code-set-to-second-code-set mapping based on at least maintained code set mappings of the OS platform of the first computer is not found.
