BPCIN0057E and BPCIN0072E error messages: Installation on Linux operating system cannot proceed because of issues with DB2 db2inst1 user

In rare occurrences, the IBM Spectrum Control installation program cannot validate the DB2® db2inst1 user during preinstallation on Linux® operating systems.

Problem

In this situation, the following messages are generated during a preinstallation check and are displayed at the beginning of the installation process:

BPCIN0057E The user name db2inst1 is not in an operating system group 
that has DB2 SYSADM authority.

BPCIN0072E The validation for user name db2inst1 has failed. 
Check to see if this user name exists or if DB2 is running.

Action

Determine whether the DB2 db2inst1 user has SYSADM authority and whether DB2 is running.

If the db2inst1 user does not have SYSADM authority or DB2 is not running, correct the problem and then continue the installation.

If the user has the correct authority and DB2 is running, cancel the installation and start the installation program again.
