Refer to the installation guides for the preinstallation requirements. Additional preinstallation requirements include the following:
You must install the following packages to use Oracle Configuration Manager on SUSE 11:
glibc-devel-32bit-2.11.1-0.17.4 libgcc43-32bit-4.3.4_20091019-0.7.35 gcc-32bit-4.3-62.198 glibc-32bit-2.11.1-0.17.4 glibc-profile-32bit-2.11.1-0.17.4 glibc-locale-32bit-2.11.1-0.17.4 gcc43-32bit-4.3.4_20091019-0.7.35
Review the following section for information about issues that affect Oracle Database installation, configuration, and upgrade:
Reenable Oracle ACFS volumes and mount points using SQL, Oracle Automatic Storage Management Configuration Assistant, or command-line utilities.
While performing Oracle Grid Infrastructure installation, if the Grid Naming Service (GNS) and Dynamic Host Configuration Protocol (DHCP) options are selected and automatic execution of root script is enabled, the installation may fail with the following error:
[INS-10008] Session Initialization failed
Workaround:
Remove the directory GI_HOME recursively before clicking the Install button on the summary page.
This issue is tracked with Oracle bug 16196582.
The following section contains information about issues related to Oracle Database 12c and associated products:
Rarely, Oracle ACFS and Oracle ADVM devices in /dev/asm are set to the root group ID while the udev rules file, /etc/udev/rules.d/55-usm.rules, specifies a different group ID. As a result, Oracle ACFS and Oracle ADVM may not mount after system restart.
Workaround:
Edit the /etc/rc.local file and add the following entry:
/sbin/start_udev
Oracle ACFS and Oracle ADVM devices are created with the expected settings according to the udev rules file.
This issue is tracked with Oracle bug 13653789.
Oracle Automatic Storage Management Configuration Assistant cannot be used to create Oracle ACFS volume with stripe column 1.
Workaround:
Use the asmcmd volcreate command or the ALTER DISKGROUP SQL statement to create the volume. After the volume is created, you can use Oracle Automatic Storage Management Configuration Assistant to create Oracle ACFS file system.
This issue is tracked with Oracle bug 16347687.
The following content is specific to release 12.1.0.2:
Refer to the installation guides for the preinstallation requirements.
Review the following section for information about issues that affect Oracle Database installation, configuration, and upgrade:
The 32-bit Oracle Database Client installation may fail on Oracle Linux 7 and Red Hat Enterprise Linux 7 on Linux x86 systems.
Workaround:
For Oracle Linux 7, install the glibc-2.17-55.0.4.el7 package.
For Red Hat Enterprise Linux 7, the issue is tracked with Red Hat bugzilla 1150282. Contact Red Hat for a fix.
This issue is tracked with Oracle bug 19028658.
The following sections contain information about issues related to Oracle Database 12c and associated products:
Oracle ACFS and Oracle ADVM May Not Mount After System Restart
Oracle Universal Installer Issue on Oracle Linux 7 and Red Hat Enterprise Linux 7
Intel C++ Compiler Error on Oracle Linux 7 and Red Hat Enterprise Linux 7
Rarely, Oracle ACFS and Oracle ADVM devices in /dev/asm are set to the root group ID while the udev rules file, /etc/udev/rules.d/55-usm.rules, specifies a different group ID. As a result, Oracle ACFS and Oracle ADVM may not mount after system restart.
Workaround:
Edit the /etc/rc.local file and add the following entry:
/sbin/start_udev
Oracle ACFS and Oracle ADVM devices are created with the expected settings according to the udev rules file.
This issue is tracked with Oracle bug 13653789.
When running the acfsdriverstate command for Cluster Verification Utility (CVU), Oracle Universal Installer, or the root scripts, you may encounter a permission denied error if the current working directory is not accessible to the user.
Workaround:
Change the current working directory to a directory where the user running the command has access, such as the user's home directory or /tmp, before running the acfsdriverstate command.
This issue is tracked with Oracle bug 18364777.
On Oracle Linux 7 (64-bit) and Red Hat Enterprise Linux 7 (64-bit), certain tools such as Oracle Universal Installer, Oracle Database Configuration Assistant, and Oracle Enterprise Manager Configuration Assistant cannot display the non-English multibyte character language messages.

Workaround:
Run the following commands for the Japanese language:
mkdir /usr/share/fonts/japanese/TrueType cd /usr/share/fonts/japanese/TrueType ln -s /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc sazanami-gothic.ttf
Run the following commands for the Chinese language:
mkdir /usr/share/fonts/chinese/TrueType cd /usr/share/fonts/chinese/TrueType ln -s /usr/share/fonts/wqy-zenhei/wqy-zenhei.ttc uming.ttf
