Comments for Oracle Database 12c Release 2 (12.2) Installation On Oracle Linux 6 (OL6) and 7 (OL7)


mistake? said...

I followed you install but on CentOS 7
and /etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf
information needs to go into /etc/security/limits.conf instead.
Or at least the installer would run after I made that change.

Hi.

I've done another install and this is definitely not necessary for OL7. The preinstall package only puts the settings in the file under "/etc/security/limits.d", not in "/etc/security/limits.conf", and I get no errors. I'v made a note of your comment in the "manual" section if others have a similar issue.

Cheers

clean db installation. see warnings: unable to allocate shared memory (large pool, unknown object, kxttIICDT,4)

Hi.

I would suggest you search on MOS to see if it is a know issue.

subhuman, your post makes me very happy. I thought I was the only one with this problem. I don't know if you figured it out by now, but this is caused by DB Express. Every time you navigate between performance and home, a new shared server process freezes at 100% CPU and you get another ORA-4030 with "kxttIICDT" in it. Neither MOS or Google return anything about it.

Marcus, really i am very unhappy with db express. i wish it would be more functional but ... only using Cloud Control (

alter system set "_ksmg_granule_size"=33554432 scope=spfile;
+ restart )

Hi,
which ip adress is generally suitable? I used the 192.168.56.107 and installation suceeded but configuration of the database failed. I've done all the other steps in the tutorial exactly like you.

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.56.107 ol7-122.localdomain ol7-122

Thanks in advance for your response!

Hi.

This depends on the Host-Only network you create in the VirtualBox networking preferences (not the VM itself). Whatever subnet you assign there, which be what your VM will need to use for its host-only adapter.

I know you are not doing RAC, but you can see how to set up the networking preferences in this article.
