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 running the tool

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

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

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 3: Start the z/OSMF server.
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.

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 marked with a critical icon `X` Setting is not correct for z/OSMF. You must fix this problem before continuing with z/OSMF. Items marked with a warning symbol `!` Setting is not optimal for z/OSMF. It is recommended that you update the setting before continuing 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 updating a setting, use the browser reload button to run the environment checker again. Repeat this process until you have resolved all of the errors and warnings.

If you are using the Internet Explorer browser:

When 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 working with Resource Monitoring task, users who plan to export the data 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.

When using the Internet Explorer 8 browser, you might experience:

Browser memory issues, if you open multiple tabs. If so, close some unneeded tabs to use less memory.
Slow responsiveness for certain data-intensive operations. If so, consider using another supported browser.

If you are using Internet Explorer 9 on a Windows 7 system, note that this browser uses Compatibility View mode by default. Here, it is recommended that you switch to Internet Explorer 9 mode, as follows:

From the Tools menu, click F12 developer Tools > Browser Mode: IE9 tab.
Click Internet Explorer 9.
