18c Grid Infrastructure installation

Confirm ‘grid’ owner groups.

[grid@z-oracle1 grid]$ id grid

uid=54331(grid) gid=1001(dba) groups=1001(dba),54321(oinstall),54333(asmdba),54334(asmoper),54335(asmadmin),54336(racdba)

Create 18c Grid Infrastructure Oracle Base, Home and admin directories e.g.

[grid@z-oracle1 ~]$mkdir -p /u01/app/18.0.0/grid
[grid@z-oracle1 ~]$mkdir /u01/app/grid

Launch installer from terminal capable of starting X session.

[grid@z-oracle1 grid]$ cd $GRID_HOME
[grid@z-oracle1 grid]$ ./gridSetup.sh

Select Clustered, non-clustered or software only installation

Update the ASM disk discovery path (if required), and select disk path for your +DATA disk group.

Before I started the 18c installer I created 3 Pure Storage volumes and configured UDEV rules to help identification. I can now select my 1TB +DATA volume and set the Redundancy to ‘External’ as the storage platform will provide the required data protection.

Provide ASM passwords and click ‘Next’

Register with Oracle Enterprise Manager, I will skip this for now, ‘Next’

Confirm Oracle ASM ‘grid’ account groups, click ‘Next’

Confirm pre-created Oracle Base location.

Select ‘Next’ and run root.sh in a separate terminal window when prompted

Review 18c Grid Infrastructure summary and click ‘Install’ to confirm installation

Run root.sh from root window.

Wait for the script to start the 18c Grid Infrastructure services, once complete click ‘OK’.

If all has gone well, you should be presented with a ‘successful’ installation screen.

Now, lets look at our first look at an 18c ASM instance, if you observant you will see I have created 2 additional ASM DiskGroups +FRA & + CONTROL_REDO.

Will check my previous Blogs and if missing will share how you can create ASM Diskgroups using ASMCLI or AMSCA (UI).

Come back in a few days to see my first 18c database Blog post.
