Apps server on AS400

I have now learned that the Apps server can run natively on the AS/400. The question I have is: I thought the JDE software is MS C++
at its core. So how can AS/400 execute MS C++ code? Has AS/400
capabilities improved in this area? Or is there some conversion
going On? Also, Since the Apps server can be multiple in number,
is it possible to have a Apps server on a NT box, and one on the
AS/400 native??

Thanks
Tom

The AS/400 uses ILE/C Compiler and should be installed if you intend on
building server packages.

No conversion going on. The same exact C code that makes up all the DLLs
sitting on a FAT client is compiled and put into *SRVPGMs on the AS/400.
All via the CRTCMOD and CRTSRVPGM commands.

Re: RE: Apps server on AS400

I See..So how is reliability/performance of running the apps as a as/400 object compared to a DLL version?
Thanks

Tom,

JDE's code is not written in C++ but in ANSI C. The compiler used on the Windows platform happens to be Microsoft's C++ compiler which which works with both C and C++ code. Since IBM (and HP and SUN) have C compilers that work with ANSI C JDE only has to to have a few platform sensitive compiler directives in their code to handle the platform differences (actually I'm sure they had to do a lot more than that to be cross platform but get the idea).

Yes, you can potentially have app servers on different platfoms, but it ups the administrative time/cost of building packages, etc for different platform types.
