HI Michael,
Sorry for late feedbak. I was busy for recovery of my nim server. I use aix base media to update TL of NIM itself, but I wrongly choosed "Install All" other than "Update All" with "smitty install", and then have to recover nim from mksysb, and then reconfigure everything.
As for cython, it is working! thanks so much.
Little bit trick for cython, both package of python.cython and python3.cython include /opt/bin/cython, if installing both python.cython and python3.cython, the latest installed package will overwrite the existing one. Just let you know this, although it is not problem to me.
Appreciate you quick response.
