Fix runInstaller [INS-32042] The Installer has detected that the user (oracle) is not member of the central inventory group: wheel

Problem Description

Oracle installation or runinstaller failed with below error message. 

[INS-32042] The Installer has detected that the user (oracle) is not member of the central inventory group: wheel

Solution Description

This is the problem with the parameter value mentioned in the /etc/oraInst.loc. value for the inst_group parameter mentioned in the  /etc/oraInst.loc should match with the group details of the oracle software installation user. 

Here in below example the inst_group value in /etc/oraInst.loc file is wrongly mentioned as wheel instead of oinstall.  Actually the software installtion user oracle is part of oinstall group rather than wheel.

[root@ol7-19 dbhome_1]# more /etc/oraInst.loc

inventory_loc=/u01/app/oraInventory

inst_group=wheel ### Wrong value. 

[root@ol7-19 dbhome_1]# id oracle

uid=1000(oracle) gid=54321(oinstall) groups=54321(oinstall),10(wheel),54322(dba),54323(oper)



Post modification the values are like this.

inventory_loc=/u01/app/oraInventory

inst_group=oinstall
