runInstaller fails at CreateOUIProcess with permission denied

Just a short post on a problem I encountered recently.

I had to install 11.2 GI and right after running the installer I got a message saying permission denied. Below is the exact error:

[oracle@testdb grid]$ ./runInstaller -silent -showProgress -waitforcompletion -responseFile /u01/software/grid/response/grid_install_20140114.rsp

2014 was really successful for me. I worked on some really interesting projects, (more...)

Troubleshooting Oracle DBFS mount issues

On Exadata the local drives on the compute nodes are not big enough to allow larger exports and often dbfs is configured. In my case I had a 1.2 TB dbfs file system mounted under /dbfs_direct/.

While I was doing some exports yesterday I found that my dbfs wasn’t mounted, running quick crsctl command to bring it online failed:

[oracle@exadb01 ~]$ crsctl start resource dbfs_mount -n exadb01

This was caused by a known bug which requires decreasing the number of parallel queries of the repository databases and start over the installation. The database had cpu_count set to 64 and parallel_max_servers to 270. After setting the parallel_max_servers to (more...)
