Hi All,
I have a situation where the client is deciding to migrate the database and applications from Solaris to RHEL on EPIC platform.
I assume that we point the makefile to Pro*C libraries on RHEL and recompile?

However I need some advise and help, as what would be the impact of such OS migration on the Pro*C code? Do we have to re-write or a simple recompile will be sufficient? Any impact on endians?

Please help.

Regs,

It depends on what you do in the code.
If there is nothing specific to the platform, you just have to recompile and link your program.

Do you decode data bytes or dump?

Thanks Michel,

The decode of data bytes are pertaining to extract each field from the MQ message i.e., From x to y bytes represent Customer ID etc. Other than this nothing.

If you receive RAW data the you may have some problems.
If you are working on Solaris X86, the endian is the same than Linux so no problem.
If you are working on Solaris OE then it could be.

Note that the problem does not come from the program compilation or link but from the data and the way you handle them.
So anyway you have to recompile and link the program, then make test to know if endian matters or not in your case.
