Installing Visual COBOL Development Hub

Note: Micro Focus offers two types of installers on UNIX and Linux - a proprietary Micro Focus installer for installing on UNIX and Linux and a standard RPM (RPM Package Manager) installer for installing on Linux.

These are the steps to install this product:

Give execute permissions to the setup file:

chmod +x setup_visualcobol_devhub_3.0_platform

Run the installer with superuser permissions:
```
./setup_visualcobol_devhub_3.0_platform
```
If you don't run this as superuser you will be prompted to enter the superuser password during the installation.

The COBOL environment is installed by default into /opt/microfocus/VisualCOBOL, (COBDIR).

SafeNet Sentinel considerations

The installation of this product could affect the SafeNet Sentinel licensed components running on your machine. During installation licensing is shutdown to allow files to be updated. To ensure the processes running on your machine are not affected, you need to use the -skipsafenet option, which skips the installation of SafeNet:
```
./setup_visualcobol_devhub_3.0_platform -skipsafenet
```
To protect the SafeNet Sentinel installation from accidental updating you can create an empty file named SKIP_SAFENET_INSTALL in /var/microfocuslicensing/ as follows:
```
touch /var/microfocuslicensing/SKIP_SAFENET_INSTALL
```
While the file is present, the SafeNet installer does not make changes to the installation or shutdown the running license daemons. If licensing needs to be updated later, remove the file and install Sentinel RMS server manually.

Note:

During the installation process, the installer configures the product's Enterprise Server System Administrator Process User ID. The Process User ID will be the owner of all Enterprise Server processes except the one for the Micro Focus Directory Server (MFDS). The Directory Server process (Enterprise Server Administration) runs as root as this allows it to access the system files and ports.

All Enterprise Server processes you start from Enterprise Server Administration run under the Process User ID which can affects the file access and creation.

By default, the installer uses the login id of the user that runs the installer for the Process User ID. To change the user id after you complete the installation, execute $COBDIR/bin/casperm.sh.
