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

Happy New Year!
So many things happened in the past six months, I really can’t tell how quickly the time passed. As people say the life is what happens to you while you are making plans for the future.
I wish I had the time to blog more in the past year and I plan to change this in the New Year!
2014 was really successful for me. I worked on some really interesting projects, (more...)
I’m more than happy that I will be speaking at this year’s Oracle Open World. The first and only time I attended was back in 2010 and now I’m not only attending but speaking as well!
Both with Jason Arneil will talk about what we’ve learned on our Exadata implementations with two of the biggest UK retailers so please join us:

I’ll be speaking at the spring conference of the BGOUG held between 13th and 15th of June. I was a regular attendee of the conference for eight years in a row but since I moved to UK I had to skip the last two conferences. My session is about Oracle GoldenGate – it will cover the basics, components, usage scenarios, installation and configuration, trail files and GG records and many more.
See you there in (more...)
The following blog post continue the EMDIAG repvfy kit series and will focus on how to troubleshoot and solve the problems reported by the kit.
The repository verification kit reports number of problems with our repository which we are about to troubleshoot and solve one by one. It’s important to notice that some of the problem are related so solving one problem could also solve another one.
Here is the output I’ve got for my (more...)
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

Just a quick post regarding OEM 12c installation where recently I had to install OEM 12c and during the repository configuration step the installation fails with error:
ORA-12801: error signaled in parallel query server P151
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...)
