Issues with Enterprise Server

HTTP 403 page

ESMAC contains defence mechanism against cross-site request forgery attacks. As a result, a 403 page is displayed in the browser if an incorrect authentication token is sent in a request to ESMAC that performs a protected operation, such as submitting a job or updating a resource definition.

If you receive a 403 page when using ESMAC, try clearing your session cookies as there might be a stale cookie value left behind which is triggering the page. If the page continues to appear, contact Micro Focus Customer Care for assistance.

Using more than one region in the same browser session

ESMAC contains defence mechanism against cross-site request forgery attacks. As a result of this, it is currently not possible to log in into two different regions within the same browser session. This is because cookies are used as part of the authentication process, and each region needs its own version of the authentication cookies to keep the ESMAC session valid.

You can work around this issue in one of the following ways:

Open each new ESMAC session in a separate private or incognito browser window for each region you want to access concurrently alongside any other running regions.
Alternatively, use ESCWA to manage your regions.

Upgrading Enterprise Server

If you upgraded from a version of Micro Focus Server and have retained any enterprise servers that have a Web Services listener, you will receive an error when you deploy informing you that the listener cannot be found. To fix this, change the listener name before deploying using one of the following methods:

From Enterprise Server Administration, change the listener name from Web Services to Web Services and J2EE.
Edit your deployment service (usually named Deployer) and add the following lines to the Configuration Information area: [destination] listener=Web Services
If your deployment service doesn't have the listener name specified, edit the base\deploy\.mfdeploy file changing the Web Services listener name to Web Services and J2EE .

Dynamic Debugging with Enterprise Server

If dynamic debugging is not enabled for the enterprise server on which you are running an application, you receive an alert when you try to debug. You need to enable dynamic debugging for the server by checking Allow Dynamic Debugging on the Edit page of Enterprise Server Administration and restarting the server or by checking Dynamic Debug on the ESMAC > Control page which will enable debugging until the server is stopped.

Debugging Assembler modules with Enterprise Server

The MFASM debugger is unable to open a window for debugging on any enterprise server region started via ESWCA, as Microsoft has permanently disabled access to the user desktop from any application started in the background and owned by "SYSTEM".

Enterprise Server Administration Web page

If the buttons on the Enterprise Server Administration Web page don't work, you need to enable Active Scripting or Javascript in your browser.

Active Content Blocked

If the Web Browser tells you it's blocking active content, when you view the Help, you need to allow active content.

Viewing the Help

You can view the COBOL Server Help in a separate browser window while you are using the Enterprise Server Administration Web interface, by clicking Contents in the menu at the left-hand side of the page. For this link to work, you must have the following in place:

An enterprise server that has a Web listener with the following entry in the [virtual paths] section: docs=<ES>/help
The enterprise server must be started

ESDEMO Configuration

The default enterprise server, ESDEMO, may not have the correct configuration information entry for its Web listener. If you encounter problems accessing the Help while you are using ESDEMO, you must correct the entry using the Edit Listener page. Note that references to this configuration entry in the context help and the Enterprise Server Configuration and Administration Guide are no longer correct and you must use the entry as specified above.

When you create a new enterprise server, a Web listener with the required configuration information entry is automatically created.

Performance monitoring - dynamic binding error

If you have two or more products installed that contain core Enterprise Server technology, then performance monitoring via Windows performance counters is only possible against the most recently installed (or repaired) product.

Further, if you install any one product, you will uninstall the performance monitoring capability for all products. This can be restored by a repair installation of the remaining product against which you wish to perform monitoring.

If you have a version of the COBOL run time loaded and try to acquire performance monitors, the installed cas0perf.dll must have been built with the runtime from the same product. If not, you are likely to get a dynamic binding error because an attempt will be made to bind to the run time that is already loaded, for example:

Dynamic binding error on run-time entry point mF-Id_dynlnk ...

If you do not need Enterprise Server performance monitoring, you can disable the capability completely by creating a new DWORD registry entry called Disable Performance Counters under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Micro Focus Server\Performance and assigning its value to 1.
