How to Install and Run the Pre-Update Enterprise Health Check Tool

To install this tool, the system must be running at least Oracle Solaris 11.3 SRU 35.

To conduct this assessment, the user must be assigned the Compliance Assessor rights profile or have all zone privileges and the solaris.compliance.assess authorization.

Oracle provides a pre-update checker to help you determine whether a system that is running Oracle Solaris 11.3 is ready to update to Oracle Solaris 11.4. The report generated by this checker identifies superseded software versions and unsupported hardware. This procedure describes how to install and run the Pre-Update Enterprise Health Check (EHC) tool and how to generate the Oracle Solaris 11.4 readiness report.

Install the required packages.
On a system that is running at least Oracle Solaris 11.3 SRU 35, install the following packages:
```
# pkg install compliance update-check
```
Verify that the ehc-update check is available.
```
# compliance list
```
Run the ehc-update check.
```
# compliance assess -b ehc-update
```
Verify that an assessment was generated.
```
# compliance list
```
Create the report.
```
# compliance report
```
The HTML report can be viewed on any browser. For failed checks, the report provides a description of the corrective action to be taken.
