Starting with z/OS V2R2, PFA uses a minimum of IBM
31-bit SDK for z/OS Java Technology Edition version 7.1.0.
You must update the ini file in the /etc/PFA/ directory
for Predictive Failure Analysis (PFA) processing to locate the Java™ code on your system. For more
information about the ini file, see How PFA uses the ini file.
Java code for PFA
is installed. The default is
/usr/lpp/bcp
. For example: 
JAVAPATH= /usr/lpp/bcp
Update
the PATH= and LIBPATH= statements
in the ini file to point to the executable code needed for JNI calls. PATH= /usr/lpp/java/J7.1/lib/s390/classic:/usr/lpp/java/J7.1/lib/s390
LIBPATH=/usr/lpp/java/J7.1/lib/s390:/usr/lpp/java/J7.1/lib/s390/classic:/lib:/usr/lib:
