Additional Requirements for UNIX

If you're using Solution Publisher on the same machine as IBM® SPSS® Modeler Server, you must ensure that kernel limits on the system are sufficient for the operation of IBM SPSS Modeler Server. The data, memory, file, and processes ulimits are particularly important and should be set to unlimited within the IBM SPSS Modeler Server environment. To do this:

Add the following commands to modelersrv.sh:
```
ulimit –d unlimited
```
```
ulimit –m unlimited
```
```
ulimit –f unlimited
```
```
ulimit –u unlimited
```
In addition, set the stack limit to the maximum allowed by your system (ulimit -s XXXX), for example:
```
ulimit -s 64000
```
Restart IBM SPSS Modeler Server.

You also need the gzip file compression utility and GNU cpio installed and on the PATH in order for the installer to be able to decompress the installation files. In addition, on the machine running SPSS Modeler Server, you should set the locale to EN_US.UTF-8.
