18c install on premises - first impressions

Mon, 10 Sep 2018 18:35:18 -0300

Hey all,

Somethings have change on 18c. Today I will explain my first impressions of this pretty new product on premises and some comparisons by older versions (PS: I classified each topic before start talk about… I hope to help you on your next upgrade)

Download: If you use download from Oracle OTN, you notice that there is only one zip for Oracle database and one zip file for grid install.
Install: now you have to unzip all content into Oracle_HOME<- they called this new way as “Simplified Image-based Oracle Database Installation”
Install: runInstaller was replaced by gridSetup.sh (in case of Grid installation) and for database Installer you still need to execute runInstall.sh
Install: you will need at least a machine with 8 GB RAM to install grid / database.
Install: for database installer, now you have both options of install (as 10g Installer) - you can choose install enterprise or Standard Edition 2.
Install: now you can choose on database install TFA during execution of root.sh.

See you. :-)

Today we will describe some impressions about 1z0-060 exam.

So, for get success in exam, you need:

Study hard on 12c architecture (CDB / PDB): how to start/ stop, create, drop, secure, etc.
Do not believe on dumps answers.

We recommend to do new features course, or have some experience on 12c first - some questions have direct relation with daily DBA tasks.

First impression on 12cR2 Oracle Clusterware install

Thu, 30 Mar 2017 15:51:24 -0300

Today we will gonna discuss about first impression on fresh install of Oracle Clusterware 12cR2 (for database, you could found some considerations here).

I install on new Oracle Linux 6.9 on Virtualbox 5.1.18 and I observe some points:

Like database install, the grid software has only one file to download (take care with uncompress the zip file. You need to uncompress on the location that you need to use the cluster software).
Oracle has added 2 diskgroups types (in 11gR2 its doesn’t are present): Flex and Extended (more information you could found here).

Pay attention with pre-requisites and space: at least, almost 40 GB was necessary for grid diskgroup if you have less than 4 nodes clusterware.
Gavin Soorma has upgrade a 12R1 Cluster. If you are planning to upgrade your cluster, consider to read this post
I install with old way Oracle ASMLIB for test purposes and it’s works! :-)
If you install on graphical mode be aware in unzip the cluster software where ORACLE_HOME grid software resides because you can not change the location of install home, as you could see below:

So, I’ll perform more tests in this test cluster. So, if you are planning to construct your own test cluster, i recommend:

First impression on 12cR2 database install

Thu, 16 Mar 2017 16:00:00 -0300

Today I’ll describe my first impressions on install the new 12cR2 (available for premises on march 2017) for linux and Solaris.

Inicially I felt a little bit strange because there are only one file for database and only one for grid install (on other versions since 11gR2, there are 2 files for database and one or more for grid - depends of version that you install).

So I downloaded and install it on OEL6.8 for study purposes.

The install process is almost similar than 12cR1 process, except you need more free space to install it (at least 8 GB).

Other point, when you unzip the single file, keep careful in uncompress on a folder (for organization, because all files will be uncompress in same directory that you are).

Then I will keep study and publish some more new features! :-)

Release schedules dates document was updated!!

Mon, 13 Mar 2017 18:33:13 -0300

Continue Hanganalyze’s post: 12.2 on-prem available for download, we see that realease date document was update on MOS (742060.1).

Basically Oracle 12.2 was released for cloud (in March 2017 for premises) and 12.2 have been supported until 2021.

So, now it’s time to think about and plan to upgrade databases 11.2.0.4 and 12.1.0.2, of course if application was compatible too! :-)

Remember, now Oracle Recertification program follow the schedules date (more information you could see in this video).
