Disk Space and Memory Requirements

Process Automation Server can use astronomical amounts of memory: its limit is 16 exabytes. If processes need more RAM than your server has available, Process Automation Server pages the extra data to disk. However, ensure that adequate disk space is available. In the improbable event that PAS runs out of both RAM and disk space, it fails.

Process Automation Server has these enhancements:

IPA Monitor

Instead of monitoring every workflow in the system constantly, create filters to show only the flows that you want to monitor. The server is then more scalable and reliable.

Note:
If your filter is too loose and too many flows start showing up, PAS cancels your filter because it returns too many results. Create a more narrow filter.

PAS is 64-bit

If you use Database actions in your workflows and connect to an Oracle database, the computer with Process Automation Server must have the 64-bit version of the Oracle ODBC driver available. SQL Server doesn’t require any special steps.

Process Automation Server stores data about workflows only in a Microsoft SQL Server database, though it can use any ODBC-compliant database for other kinds of data.

Easier and more fault-tolerant switchovers

• For planned switchovers, Process Automation Server requires no special actions.

• For unplanned switchovers, Process Automation Server requires no special actions if you can start the now-backup-server.

• If you cannot start the now-backup server for unplanned switchovers, run the flow_admin.exe tool and follow the prompts to restart flows from the backup server.
