Oracle Enterprise Linux 7: How to stop bash tab completion from escaping the dollar $
Did you ever wonder why bash in Oracle Linux, Red Hat Enterprise Linux and other recent Linuxes escapes the dollar sign ($) when completing paths with the tabulator (tab) key like that: [oracle@oratest01 ~]$ (KLM12102) ls -l \$ORACLE_BASE/diag Answer In bash >= 4.2.29 you have a “direxpand” option, which is NOT set by default.

How to disable Oracle ACFS drivers / registry resource
Sometimes an installed ACFS can cause trouble, especially if we don’t or can’t use it (e.g. when not using an UEK Linux kernel, like with SuSE Linux Enterprise Server SLES).

USM driver install actions failed /u01/app/grid/11.2.0/perl/bin/perl -I/u01/app/grid/11.2.0/perl/lib -I/u01/app/grid/11.2.0/crs/install /u01/app/grid/11.2.0/crs/install/rootcrs.pl execution failed USM drivers […]
