Application Building Guide

Building HP-UX Applications

This chapter provides detailed information for building DB2 applications on HP-UX. In the script files, commands that begin with db2 are Command Line Processor (CLP) commands. Refer to the Command Reference if you need more information about CLP commands.

Notes:

1. The +DAportable option is used in the compile and link steps of the DB2 build files and makefiles. This option generates code compatible across PA_RISC 1.1 and 2.0 workstations. The use of this option comes with a slight performance cost. To improve performance, you can remove the +DAportable option from the build files and makefiles provided in the sqllib/samples directory. Without this option, you may get a warning similar to the following when building HP-UX programs:

      (Warning) At least one PA 2.0 object file (<filename>.o) was detected.
      The linked object may not run on a PA 1.x system.
   

   where <filename> is the program file you are compiling.

   Unless you have a PA_RISC 1.1 or 2.0 system, this warning does not apply.

2. If you are migrating DB2 from HP-UX Version 10 or earlier to HP-UX Version 11, your DB2 programs must be re-precompiled with DB2 on HP-UX Version 11 (if they include embedded SQL), and must be re-compiled. This includes all DB2 applications, stored procedures, user-defined functions and user exit programs. As well, DB2 programs that are compiled on HP-UX Version 11 may not run on HP-UX Version 10 or earlier. DB2 programs that are compiled and run on HP-UX Version 10 may connect remotely to HP-UX Version 11 servers.
