In last week, I installed an Oracle RAC on openSUSE 15.2 and got some issues. Although the installation was successful finally, it still took me much more time than the same thing on RHEL.
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:
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.
