I think that some confusion was caused by the recommendation to include 
XPLink modules in LPA.  The section of the manual that points to the 
member references C/C++.  XPLink is actually, a calling convention that is 
used by C/C++.  The recommendation should probably have been to include 
C/C++ runtime modules in dynamic LPA.

Pointing to the specific manual and section title would have been good 
since the specifics could change.   I did a quick check that manual prior to
Kirk posting, as that is where I expected to find it but somehow missed
it within all the XPLINK hits I had.   I see now that 3 of the modules
in the sample LPA member (2 + 1 alias) are documented as XPLINK
in appendix 1.3.2.  CRTEC128 and alias C128 are not mentioned
at all in that section.

If you don't get a better answer from someone like Kirk, maybe you can
open a PMR with IBM LE or C++ support.

I did find this old Redbook: XPLink:  OS/390 Extra Performance Linkage 
http://www.redbooks.ibm.com/redbooks/pdfs/sg245991.pdf

There is at least this one module that is mentioned - 
" This XPLink LE C/C++ RTL exists in the CELHV003 member of the
CEE.SCEERUN2 data set."

Good luck.   Let us know what you find out if you open a PMR.

Regards,

Mark

Seems like I was misunderstood,

I was looking for documentation/recommendations for this;

Put the XPLINK modules in SCEERUN2 in the dynamic LPA.

Hi

I think the best you can do to get some LLA fetch statistic and put the 
heavily used modules from SCEERUN2 to LPA

(We are using here MXI to get this statistic)
We heavily use here the C++ compiler, so the compiler modules are in the 
dynamic LPA.
