Installation Considerations for Optimal Performance

For optimal performance, Serena recommends the following:

• Install the server as the root user or system user account. The server should be installed as the root user on UNIX/Linux and as a local system user on Windows. Running in this manner avoids all permission errors.

• Install each agent as a dedicated system account. Ideally, the account should only be used by Deployment Automation. Because Serena Deployment Automation agents are command execution engines, it is advisable to limit what they can do on host machines by creating dedicated users and then granting them appropriate privileges. If you install an agent as the root user (or local system user on Windows), ensure that agent processes cannot adversely affect the host file system.

• Except for evaluation purposes, do not install an agent on the Deployment Automation server machine. Because the agent is resource intensive, installing one on the server machine can degrade performance during large deployments.

• Install a single agent per host machine. Multiple agents on the same machine can negatively impact each other's performance. When you must install multiple agents, you might see performance degradation when multiple agents are busy simultaneously.
