Arabic Plus Pack and Asian Plus Pack
64-bit Required for Arabic Plus Pack and Asian Plus Pack
Arabic Plus Pack and Asian Plus Pack databases are no longer supported on 32-bit computers. You
must use a 64-bit computer when using these databases.
Installing Arabic Plus Pack Data
Arabic Plus Pack data is used by the Advanced Matching module for handling data in Arabic. The Advanced
Matching Module database load utility currently does not support the Arabic Plus Pack. To install
the Arabic Plus Pack, copy the file g1-cdq-cjki-arabic-7.0.jar to /modules/server/modules/tables/ext.
You do not need to restart the server.
Installing Enterprise Tax Module Databases on Unix or Linux
The procedure for installing Enterprise Tax Module databases on Unix and Linux has been updated to
avoid an error that can occur if the database is larger than 2 GB. If you are installing a database larger
than 2 GB, type the following commands at the command prompt before installing the database:
export LARGE_FILE_LIMIT_2TB=1
export USE_LARGE_FILE_API=1
For complete instructions on installing Enterprise Tax Module databases, see the Spectrum Technology
Platform Installation Guide.
JVM Performance Tuning
26
There are JVM options that will yield performance gains with certain hardware. These are advanced
options and can cause unexpected behavior when used incorrectly (possibly even JVM crashes). We
recommend that you contact technical support if you want to explore increasing performance by tuning
the JVM.
• On multiple CPU computers the -XX:+UseParallelGC option can be added to improve GC processing.
• We have also seen performance increases by adding these options, although on some hardware they
have been known to cause JVM crashes.
• -Xmn512m
• -XX:+AggressiveOpts
