Verifying your workstation with the environment checker

To work with z/OSMF, your web browser and workstation require a number of settings for proper functioning. z/OSMF includes an environment checker tool to help you verify these settings. The environment checker tool inspects your web browser and workstation operating system for compliance with z/OSMF requirements and recommended settings.

Before you run the tool

Check to ensure that your workstation is set up correctly for z/OSMF. See Preparing your workstation for z/OSMF.

Your workstation requires a compatible operating system and web browser. For more information, see Software prerequisites for z/OSMF.

Ensure that your browser is enabled for JavaScript. For instructions, see Table 1 or Table 1.

Running the tool

To run the tool, do the following:

Open a web browser to the environment checker tool:
https://hostname:port/zosmf/IzuUICommon/environment.jsp
Where:
- hostname is the hostname or IP address of the system on which z/OSMF is installed
- port is the secure application port.
To find the hostname and port, see the link for z/OSMF in message IZUG349I. This message was written to the z/OSMF server job log, as described in Step 4: Verify server initialization.
Follow the instructions for your particular browser in the online help for the tool.

Understanding the results of the tool

Table 1 describes the layout of the environment checker report.

Table 1. Columns in the environment checker tool results page
Column	Description
Environment Option	Browser setting that was examined by the environment checker tool.
Settings as of date-time	Findings from the most recent invocation of the tool. This column indicates potential problems with your browser. In the column heading, the date and time (`date-time`) is represented in ISO 8601 format, a standard provided by the International Organization for Standardization (ISO). In this format: Calendar date is represented in year-month-day format (`yyyy-mm-dd`). Time of day (T) is based on the 24-hour clock: `hh:mm:ss:mmm`. `Z` indicates zero offset from coordinated universal time (UTC). In the report, the status of each setting is indicated, as follows: Items that are marked with a critical icon `X` Setting is not correct for z/OSMF. You must fix this problem before you continue with z/OSMF. Items that are marked with a warning symbol `!` Setting is not optimal for z/OSMF. It is recommended that you update the setting before you continue with z/OSMF. No error indication Setting is correct for z/OSMF.
Requirements	Recommended setting for your environment.

For the steps to resolve a problem, see the appropriate entry in the tool's online help. After you update a setting, use the browser reload button to run the environment checker again. Repeat this process until you resolve all of the errors and warnings.

If you are using the Internet Explorer browser:

When you are working with WLM service definitions, ensure that automatic prompting for file downloads is enabled for the web link (a URL) to the active z/OSMF instance. See Enabling automatic prompting for file downloads.
When you are working with Resource Monitoring task, users who plan to export the data that is collected in a dashboard to a CSV file should ensure that automatic prompting for file downloads is enabled. See Enabling automatic prompting for file downloads.
Do not use the browser with the Compatibility View feature enabled, which allows web sites to appear as they do when viewed with Internet Explorer Version 7. Some z/OSMF functions might not work correctly because Internet Explorer 7 is not supported.

If you are using the Microsoft Edge browser on a Windows 10 system:

When you are working with the Sysplex Management task or the System Status task, you might experience problems with the zoom function on graphical views. If so, upgrade the browser to a later version and try again. If the problem persists, use another tested browser.
