System Requirements for Servers

Before installing Adaptive Server ensure that your system is updated with the latest patches and system requirements. Do not use a patch that is earlier than the version suggested for your operating system. Use the patch recommended by the operating system vendor, even if it supersedes the patch listed.

To list all currently installed patches and display the operating system version level, enter:

For Sun Solaris:
```
showrev -p
```

Note: The Java Virtual Machine (JVM) and associated Adaptive Server support requires a minimum of 250MB of virtual memory space. You may need more memory depending on the requirements of the individual java executions. You may need to adjust the memory parameters when running java to ensure that the java has enough virtual memory space to start, and that both Adaptive Server and java tasks successfully coexist.

In particular, systems that have Adaptive Server total memory set to a value higher than 1.5GB (or 2.5GB on some Enterprise servers) may experience problems and may have to reduce Adaptive Server total memory.

Note: To use the Java in the database feature, Solaris 10 is required.
