Place a Server in Maintenance Mode

The maintenance service disables non-essential services of a running IDM instance, in preparation for an update to a later version. When maintenance mode is enabled, services such as recon, sync, scheduling, and workflow are disabled. The complete list of disabled services is output to the log file.

The router remains functional and requests to the maintenance endpoint continue to be serviced. Requests to endpoints that are serviced by a disabled component return the following response:

404 Resource endpoint-name not found

Before you enable maintenance mode, temporarily suspend scheduled tasks.

Manage maintenance mode over REST as follows:

Enable maintenance mode

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/maintenance?_action=enable"
{
  "maintenanceEnabled": true
}

Disable maintenance mode

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/maintenance?_action=disable"
{
  "maintenanceEnabled": false
}

Check if a server is in maintenance mode

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/maintenance?_action=status"
{
  "maintenanceEnabled": false
}

If the server is in maintenance mode, the command returns "maintenanceEnabled": true; otherwise it returns "maintenanceEnabled": false.
