  Maintaining Availability During Routine Maintenance
Adding More Capacity
To add more capacity to your Process Orchestrator environment, just add another Process Orchestrator 
server. Before you can do that, you must:
  •
Be able to connect to an existing Process Orchestrator server
  •
Have permission to add a new server
  •
Acquire the credentials for connecting to the Process Orchestrator process database
For information about how to add a new server, see the Cisco Process Orchestrator Installation Guide.
Relocating a Process Orchestrator Server
To relocate a Process Orchestrator server:
Step 1
Add a new server to the environment (see 
).
Step 2
Uninstall Process Orchestrator from the old server (see the Cisco Process Orchestrator Installation 
Guide)
.
Maintaining the Database
The following sections describe how to maintain the Process Orchestrator database:

 Grooming the Database
Process Orchestrator provides settings to control grooming of the following types of objects:
  •
Various sections of its Process and Reporting databases. 
  –
The Process database instances are primarily useful for viewing prior instances in the main 
expert UI, understanding the specific activities which were executed, querying the activity 
instance inputs, outputs, and other execution details typically useful in troubleshooting and 
development scenarios. 
Grooming the Process database can help optimize performance. Reducing the database size can 
improve database insert speeds, but at a cost of being able to view older process instances in the 
UI. If you perform complex views including large numbers of historic processes, the database 
and UI must deal with the larger data volumes. Larger views might also mean larger data 
payloads coming through the server to the UI. This factor therefore not only affects the database 
layer, but also the server and UI performance.
Grooming the Process database as tightly as business scenarios allow optimizes performance of 
both the Process Orchestrator Server and UIs. For example, if no business requirement exists to 
monitor and troubleshoot failed processes past the end of a shift, setting grooming for one day 
might be appropriate.
