# Configuration File: bse_vars

In the Configuration File bse_vars dialog box you can add environment variables to the runtime environment of the porting set.

During an installation these variables are added or updated:

- MAX_LTS_SERVERS

  This variable is used for installation of language packs to be executed in parallel. Each language pack is installed with its own bshell. For each bshell a server can be assigned.

  An example with 4 MAX_LTS_SERVERS

  The specified number of processes installs an equal quantity of Language Packs in parallel. When more than 4 Language Packs must be installed, the next Language Pack starts when one of the previous Language Packs has finished.

- JAVA_HOME

  This variable is used to find java. Java is required for integration with several external programs. Specify the path to the java version to use, for example: C:\Program Files\Java\jre1.8.0_152

  You can specify this later if you do not know the correct java version or if java is not installed yet. If you do not set the path a warning message is displayed.

With environment variables the bshell and database drivers can also be informed where to find the required shared libraries. Note that per platform different names can be used for the same environment variable. For example;

- LD_LIBRARY_PATH
- LIB_PATH
- SHLIB_PATH

You can specify the `${BSE}/lib/bse_vars` file with information about the JavaRuntimeEnvironment shared libraries, the DB2 database and Solution License Manager (SLM). The content of a `bse_vars` file can look like this:

    MAX_LTS_SERVERS=4
    JAVA_HOME=c:\program files\java\jre1.8.0_152
    SHLIB_PATH=/opt/IBMdb2/V9.0/lib:/opt/java1.3/jre/lib/PA_RISC2.0/classic:/opt/java1.3/jre/lib/PA_RISC2.0:/usr/baan/shared/shlib

With the `BSE_CLASSPATH` variable extra paths can be added to the `CLASSPATH`. The bshell prepends the `BSE_CLASSPATH` to the `CLASSPATH` variable and pass them on to Java Virtual Machine (JVM). This can be used for SLM and the Adapter for Infor LN or Baan.

See the SLM or Adapter for Infor LN or Baan documentation for specific information.
