Problem

When trying to install Micro Focus Server Express 5.1, the install program shows this error:

Please confirm your understanding of the above reference environment
details (y/n): y
bin/cobconvstrtest: error while loading shared libraries: libgcc_s.so.1: wrong ELF class: ELFCLASS64.

Resolution

Even though the products are supported on 32 bit and 64 bit platforms the installer itself will still need a 32 bit C compiler. Install the 32 bit C compiler and the installation will then be possible.

Problem:

RM/InfoExpress can be used to create new COBOL indexed files.  For that purpose, RM/InfoExpress can be configured to create new files using a specific user id with specific file permissions.

Resolution:

In order to get the InfoExpress server to create files with the correct permissions, you will need to execute the InfoExpress server from a shell script that sets the correct umask. This should allow you to control the shell that the InfoExpress server is created in. This will give you control over the permissions of files created using InfoExpress.

UNIX-like operating system, have the function, "umask", which can be used to change the default permissions for newly created files for any user.

For more information regarding umask, please consult the man pages for your operating system.

Web-to-host will not work with Edge because Microsoft has dropped support for most plugins in the Edge browser. This means that Java, ActiveX, Silverlight, and other plugins are no longer supported. For this reason Microsoft has included Internet Explorer 11, which does support these plugins, on Windows 10 and it should work with Web-to-Host.

 

Please contact Micro Focus SupportLine should you have any further questions regarding this matter.

Close all active Web-to-Host and the Internet explorer windows.

Launch file explorer and navigate to the following location:

Locate a file with the same name as the session name. For instance, if the session name is mysession.html then its settings file will be saved as mysession.cph. Delete your .cph file.

Now launch the session again and print again.

A single page should be printed for each screen.

Please contact Micro Focus SupportLine shall the problem still persists.

Note: Please make sure that your session doesn’t have the “print area setup” feature enabled.

 

Please contact Micro Focus SupportLine if are experiencing the problem with this feature enabled for the session.
