Understanding Scanning
WebLogic Management supports on-demand and scheduled scans based on the domain scan paths and discovery settings. The service discovers new WebLogic domains and changes to existing domains.

Pre-General Availability Draft Documentation Notice
This documentation is in pre-General Availability status and is intended for demonstration and preliminary use only. It may not be specific to the hardware on which you are using the software. Oracle Corporation and its affiliates are not responsible for and expressly disclaim all warranties of any kind with respect to this documentation and will not be responsible for any loss, costs, or damages incurred due to the use of this documentation.
When WebLogic Management is enabled for a managed instance, the service becomes aware of the instance by detecting its heartbeat. The service then begins to scan the instance for WebLogic domains using preconfigured file system paths. When the scan detects the presence of a WebLogic domain, the plugin reports discovery details to the service. WebLogic Management stores the discovered information and updates it on subsequent scans.
For a complete list of information collected, see Data Responsibilities.
If during the initial discovery scan or any subsequent scans, WebLogic Management cannot detect any WebLogic servers, see Scan Does Not Detect Any Servers.
Scheduled scans
Scheduled scans are configured per compartment, by default, with preset values for the frequency of scans and the domain home paths:
- Domain scan frequency = 6 (hours)
- Domain home paths =
/u01/data/domains,/u01/data/, and/opt/domains
Scheduled scans run a series of checks on all managed instances in a compartment that:
- identify new domains and servers
- identify changes to existing domains and servers
- report if the servers are on the recommended patches
- report if the domains can be patched
You can change the scheduled scan configuration for the compartment or override the compartment configuration at the managed instance level.
On-demand scans
On-demand scans let you run scans on managed instances and domains outside of the schedule. On-demand scans run a series of checks on selected managed instances or selected domains in a compartment that:
- identify new domains and servers
- identify changes to existing domains and servers
- report if the servers are on the recommended patches
- report if the domains can be patched
