I list them here and hope to help more people.
1. No gcc48
zypper addrepo https://download.opensuse.org/repositories/devel:gcc/openSUSE_Leap_15.2/devel:gcc.repo zypper refresh zypper install gcc48
More details could be found on below link:gcc48 on SuSE/OpenSUSE
2. Passwordless SSH connectivity check will be failed
Workaround : (if your unix admin allows it) Before installation, as root user: (please change the path if the location of your "scp" is not the same with below) # Rename the original scp. mv /usr/bin/scp /usr/bin/scp.orig # Create a new file </usr/bin/scp>. vi /usr/bin/scp # Add the below line to the new created file </usr/bin/scp>. /usr/bin/scp.orig -T $* # Change the file permission. chmod 555 /usr/bin/scp After installation: mv /usr/bin/scp.orig /usr/bin/scp
Another temporary solution is by downgrading openssh to earlier version(openssh-7.6p1-7.8.x86_64) on the installation node, then retry.
3. dbca will fail
vi $GRID_HOME/cv/admin/cvu_config vi $ORACLE_HOME/cv/admin/cvu_config CV_ASSUME_DISTID=SUSE12 [If you are getting error in case of oracle 12C prerequisites check then set CV_ASSUME_DISTID=SUSE12 parameter in database/stage/cvu/cv/admin/cvu_config file and retry. ]
4. After reboot, the crsd failed to start
Please find note Doc ID 2270947.1 for more detail.
I did below part and this problem was fixed.
Modify the /etc/ld.so.conf adding /lib64/noelision as the FIRST entry. It should look similar to the following: /lib64/noelision /usr/local/lib64 /usr/local/lib include /etc/ld.so.conf.d/*.conf # /lib64, /lib, /usr/lib64 and /usr/lib gets added # automatically by ldconfig after parsing this file. # So, they do not need to be listed. 3. Create a link in $GI_HOME/lib for the noelision version of the libpthread library: # ln -s /lib64/noelision/libpthread-2.19.so $GI_HOME/lib/libpthread.so.0
So you'd better do the workaround before the installation for the issue 4.
For the production environments, I always recommend the certified operating systems.
