Oracle 11g stuck at installation in oracle linux no error msg only showing | and stuck
It is very common for the 11.2 installer to throw an error on OL7/RHEL7 at the phase where the agent is being built. Based on your screenshot, that is where your installer was (Building Agent Libraries), but it was unable to display the dialog window for it. This can be fixed by editing $ORACLE_HOME/sysman/lib/ins_emagent.mk, and replacing:

$(MK_EMAGENT_NMECTL)

with:

$(MK_EMAGENT_NMECTL) -lnnz11

and finally clicking Retry. But the installer is unable to display the dialog on your system.

Operating System Requirements


CentOS is not a supported Linux distribution.
Oracle Linux and Red Hat Enterprise Linux 7 are certified starting with 11.2.0.4.


If you have access only to database version 11.2.0.1, then use Oracle Linux 6 or Red hat Enterprise Linux 6.
