Bug 26708302

Deinstallation of Oracle Real Application Clusters (Oracle RAC) home on shared Network Attached Storage (NAS) fails to delete the directory $ORACLE_HOME/deinstall and returns the following error:

Failed to delete the directory $ORACLE_HOME/deinstall. Either user has no permission to delete or it is in use.

Workaround:

Manually delete the $ORACLE_HOME/deinstall folder as either the Oracle RAC owner or as root.

Bug 36429384

If the CSSD process in Oracle Grid Infrastructure 19c crashes on Oracle Linux 9 or Red Hat Enterprise Linux 9, then permission issues may occur during recovery when attempting to open Grid Interprocess Communication (GIPC) listening endpoints.

This issue is caused by the default sysctl setting:

fs.protected_regular = 1

Workaround

If your security policy permits, set the sysctl parameter to 0.

# sysctl fs.protected_regular=0

To make this change persistent, add it to a sysctl configuration file. For example:

# cat > /etc/sysctl.d/99-local.conf <<EOF
fs.protected_regular=0
EOF

Bug 38999821

Oracle Machine Learning for R 2.0 (OML4R) fails on Oracle Linux 9, Oracle Linux 10, Red Hat Enterprise Linux 9, and Red Hat Enterprise Linux 10 because the system cannot resolve the /lib64/libreadline.so.7 library.

Oracle Machine Learning for R 2.0 requires Oracle R Distribution 4.4.1 on Oracle Linux 9 and Oracle Linux 10 with Oracle Database 19c. The OML4R packages included with Oracle Database 19c were built with Oracle R Distribution 4.0.5 and are incompatible with Oracle R Distribution 4.4.1. Rebuild the OML4R packages with Oracle R Distribution 4.4.1.
