On Red Hat 8.x s390, the RPM non-root install method is not supported due to errors given by cpio. You receive the following messages:
error: unpacking of archive failed on file /usr/lib/.build-id/1b/af99f26c6b4c00ca499a3199a574b73aeb3854;6092b79c: cpio: symlink failed - No such file or directory error: Micro_Focus_cobol_server-7.0.0.0-100700.s390x: install failed
As a result, the installation in this scenario is incomplete.
If you are using AFS/Kerberos authentication to log onto your Linux system then you need to ensure you have a local user ID which SOA and Enterprise Developer components of the product can use. This user ID must be set up prior to running the installer. When running the installer you need to specify -ESadminID=[User ID] on the command line so it is used by the installer.
You need to configure the computer hostname to ensure the license server will start properly.
To avoid performance issues, "localhost" and the computer hostname must not both be mapped to IP address 127.0.0.1. You should only map "localhost" to IP address 127.0.0.1.
The following is an example of how to specify these entries correctly in the /etc/hosts file:
127.0.0.1 localhost.localdomain localhost IP machinelonghostname machineshorthostname
where IP is the unique IP address of the computer in xx.xx.xx.xx format.
