We are moving to 7.3, already did on development LPAR, going to do this
on one production LPAR this weekend.

I understand that the default Java version at 7.3 is Java 8 32-bit. But
there's a document,
https://www.ibm.com/support/docview.wss?uid=nas8N1019917, that says that

___IBM recommends the 64-bit version___.

I asked about this, and was told that you risk running out of memory
with the 32-bit, hence, the recommendation.

OK, so how do we set this as the default for the system, not in
individual jobs, but for everything.

Notice *SYS and the JAVA properties environment variables, below.

Work with Environment Vars (*SYS)

Type options, press Enter.
1=Add 2=Change 4=Remove 5=Display details 6=Print

Opt Name Value

QIBM_REX_FIND_SRCMBR '*BYMBRNAME'
CLASSPATH '/java/jdbc/sqljdbc4.jar:/opt/jvaga' >
QIBM_RPG_JAVA_PROPERTIES '-Djava.version=1.6;-Djava.awt.head' >
LANG '/QSYS.LIB/EN_US.LOCALE ' >
QIBM_MULTI_THREADED 'Y'
