<p>z/OS introduced the concept of Extra Performance Linkage (XPLINK) to
|
||||
bring performance improvement opportunities to call-intensive C and C++
|
||||
applications such as ICU. XPLINK is enabled on a DLL-by-DLL basis, so
|
||||
if you are considering using XPLINK in your application that uses ICU,
|
||||
you should consider building the XPLINK-enabled version of ICU. You
|
||||
need to set ICU's environment variable <code>OS390_XPLINK=1</code>
|
||||
prior to invoking the make process to produce binaries that are enabled
|
||||
for XPLINK.</p>
|
||||
|
||||
<p>Note: XPLINK, enabled for z/OS 1.2 and later, requires the PTF for
|
||||
PQ69418 to build XPLINK-enabled binaries.</p>

|

|

<li>
|
||||
<p>When you build ICU on a system such as z/OS 1.2, the binaries that
|
||||
result can run on that level of the operating system and later, such as
|
||||
z/OS 1.3 and z/OS 1.4. It's possible that you may have a z/OS 1.4
|
||||
system and, for example, need to deliver binaries on z/OS 1.2 and
|
||||
above. z/OS gives you this ability by targetting the complier and
|
||||
linker to run at the older level, thereby producing the desired
|
||||
binaries.</p>
|
||||
|
||||
<p>To set the compiler and LE environment to OS/390 2.10,
|

specify the following:</p>

<samp>./runConfigureICU OS390V2R10</samp>
