Environment Maintenance Mode
Maintenance Mode allows you to prevent changes within an Environment. Maintenance Mode is switched on and off via the ‘Set Maintenance Mode’ (SETMNTMDE) command within the HALPROD library (where PROD is the name of your environment).
If you try to access an environment that is currently operating in Maintenance Mode the following warning message is displayed:
When activated, the ‘Set Maintenance Mode’ (SETMNTMDE) command has a parameter to allow you to end the Halcyon monitors. The options are as follows:
| *MNT | End all Monitors EXCEPT the Action, Network Receive and Network Send Monitors. This is the default value |
| *ALL | End ALL Monitors |
| *NONE | Do not end any Monitors |
When Maintenance Mode is active, a reverse image red ‘Maint Mode’ is shown on the right hand side of Halcyon menus. No changes are allowed within the Environment other than by ‘Import Environment’ (IMPENV) and exports from other systems and environments. As such you are only allowed to start the Network and Action Monitors - all other Monitors are prevented from starting.
