DBCA: Software + DB Creation

Hi Arthur, welcome to the guide "DBCA: Software + DB Creation"

With this guide, you will be able to teach Marvin how to get Oracle Databases on your RAC cluster

We are assuming you already have your Software downloaded and ready in node1 of your cluster.

If that is not the case, please go to Oracle Database Software Downloads

or to Oracle Software Delivery

On these cases, we are creating the DB assuming not only some of the
default configuration settings, but also assuming the "oracle_home"
software has not "SQL patches" or "Bundle Patches" on them.

A good practice is always to check the system for invalid objects
after its creation and in some cases, execute "datapatch" (for 12c+
systems) and scripts like "utlrp.sql" or "catbundle.sql" to make sure
the DB has all its objects valid and all patches actives.

Have a look to these articles for more info on this:

Do you have to execute catbundle.sql when you create a new 11g
database?

Do you have to execute β€œdatapatch” when you create a new
database?

DBCA 12c and "datapatch.pl" - things to
know

Oracle 11.2.0.4 Silent Installation

Get 11.2.0.4 files from MOS, since OTN files are 11.2.0.1

https://updates.oracle.com/Orion/AdvancedSearch/process_form?search_style=9&language=0&patch_type=patchset&incl_prod=&incl_prod_checked=yes&release=80112040&plat_lang=226P&product=9480#query_link

Files:

p13390677_112040_Linux-x86-64_1of7.zip

p13390677_112040_Linux-x86-64_2of7.zip Unless you want to install
11.2.0.1 and then upgrade to 11.2.0.4... Im sure that is also fun!!

In order to be able to install 11g Software as RAC we will need to make sure CRS flag is present in the Inventory.xml.

Is possible you wont need to change anything, but on some cases you will be prompted with some errors if this is not set explicitly since DBCA wont "see" the cluster

[oracle@rac1-node1 ~]$ cp -p /u01/app/oraInventory/ContentsXML/inventory.xml /u01/app/oraInventory/ContentsXML/inventory.xml.bk

What we are going to do first, is just install Oracle DB Software.

Let's create a response file for "Software only" making sure we have correct "oracle.install.responseFileVersion" and "oracle.install.db.CLUSTER_NODES" is listing all RAC cluster nodes:

[oracle@rac1-node1 database_11.2]$ cat db_swonly.rsp
## db_swonly.rsp ##
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0
oracle.install.option=INSTALL_DB_SWONLY

ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.EEOptionsSelection=false
oracle.install.db.DBA_GROUP=oinstall
oracle.install.db.isRACOneInstall=false
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE

oracle.install.db.config.starterdb.installExampleSchemas=false
oracle.install.db.config.starterdb.enableSecuritySettings=true
oracle.install.db.config.starterdb.automatedBackup.enable=false

SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
oracle.installer.autoupdates.option=SKIP_UPDATES

Now, we just need to execute DBCA in silent mode with the response file created and the system will make sure DB software is installed in both RAC cluster nodes:

[oracle@rac1-node1 database_11.2]$ ./runInstaller -silent -responseFile /u01/Installers/database_11.2/db_swonly.rsp -showProgress -ignorePrereq

Remember to read the output in your screen (I know.. is not always the most exciting part, isn't it..?) and execute the root script as root in all of the RAC cluster nodes:

[root@rac1-node1 ~]# /u01/app/oracle/product/11.2.0/dbhome_1/root.sh
Check /u01/app/oracle/product/11.2.0/dbhome_1/install/root_rac1-node1.raclab.local_2018-12-14_21-31-46.log for the output of root script

[root@rac1-node2 ~]#

Since we have now the Software in place, we will be able to create a DB on that.

For this part of the journey, we are just creating a DB with most of its default option.

We will explore DB templates personification under DBCA: Modify Templates and clone Database

## Command Example ##

/u01/app/oracle/product/11.2.0/dbhome_1/bin/dbca

If all completed as it should (of course it did right? why wont the universe just follow our desires...) you should be able to see the DB integrated in Clusterware and the DB name (no the intances) int your oratab files ("/etc/oratab" by default in Linux)

Oracle 12.1 Silent Installation

Let's create a response file for "Software only" making sure we have correct "oracle.install.responseFileVersion" and "oracle.install.db.CLUSTER_NODES" is listing all RAC cluster nodes:

[oracle@rac1-node1 database_12.1]$ cat db_swonly.rsp

Lets create our first Database now that we have the software ready.

Warning If you want to use DB password file in ASM (recommended for
12c), the COMPATIBLE.ASM disk group attribute must be set to at least
12.1 Visit the following doc for more info Shared Password File in a Disk
Group

Lets use the "General Purpose" template for now and we will explore more about Templates in DBCA: Modify Templates and clone Database

## Command Example ##

Since we are talking about 12c database, shouldn't we try to create the Database as container and add a couple of PDBs?... yeah.. lets do it.

On this case, the system will create 2 pdbs (PDB1 and PDB2 since) adding the the following:

[...]
-createAsContainerDatabase true \
-numberOfPdbs 2 \
-pdbName pdb \
-pdbAdminPassword Welcome1 \ [...]

## Command Example ##

/u01/app/oracle/product/12.1.0/dbhome_1/bin/dbca \

[root@rac1-node1 ~]# /u01/app/oracle/product/12.2.0/dbhome_1/root.sh
Check /u01/app/oracle/product/12.2.0/dbhome_1/install/root_rac1-node1.raclab.local_2018-12-14_19-32-40-024024481.log for the output of root script


[root@rac1-node2 ~]# /u01/app/oracle/product/12.2.0/dbhome_1/root.sh
Check /u01/app/oracle/product/12.2.0/dbhome_1/install/root_rac1-node2.raclab.local_2018-12-14_19-32-49-503525536.log for the output of root script

Lets create our first Database now that we have the software ready.

Warning If you want to use DB password file in ASM (recommended for
12c), the COMPATIBLE.ASM disk group attribute must be set to at least
12.1 Visit the following doc for more info Shared Password File in a Disk
Group

Lets use the "General Purpose" template for now and we will explore more about Templates in DBCA: Modify Templates and clone Database

## Command Example ##

/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca \
-silent \
-createDatabase \
-templateName General_Purpose.dbc \
-gdbName db122  \
-sid db122  \
-SysPassword Welcome1 \
-SystemPassword Welcome1 \
-emConfiguration NONE \
-storageType ASM \
-redoLogFileSize 50  \
-diskGroupName DATA2 \
-characterSet AL32UTF8 \
-nationalCharacterSet AL16UTF16 \
-totalMemory 1024 \
-databaseType MULTIPURPOSE \
-sampleschema true \
-ignorePreReqs \
-nodelist rac1-node1,rac1-node2


## Output ##

Now, you can confirm that the DB is running in all cluster nodes and add the Instances entries to oratab:

[oracle@rac1-node2 ~]$ srvctl status database -d db122 -v
Instance db1221 is running on node rac1-node1. Instance status: Open.
Instance db1222 is running on node rac1-node2. Instance status: Open.


[oracle@rac1-node1 bin]$ cat /etc/oratab

Like we did in 12.1, we can create a container DB with couple of PDBs

PDBs Services Conflict

To avoid PDBs automatic service conflicts, avoid creating the PDBs
with same name as they have in other Container even if they are
different versions. The system will prompt to an error if it tries to
create "PDB1" in more than one container since the "listener service"
will be called the same

## Command Example ##

/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca \
-silent \
-createDatabase \
-templateName General_Purpose.dbc \
-gdbName cdb122  \
-sid cdb122  \
-createAsContainerDatabase true \
-numberOfPdbs 2 \
-pdbName pdb2 \
-pdbAdminPassword Welcome1 \
-SysPassword Welcome1 \
-SystemPassword Welcome1 \
-emConfiguration NONE \
-storageType ASM \
-redoLogFileSize 50  \
-diskGroupName DATA2 \
-characterSet AL32UTF8 \
-nationalCharacterSet AL16UTF16 \
-databaseType MULTIPURPOSE \
-sampleschema false \
-ignorePreReqs \
-nodelist rac1-node1,rac1-node2


## Output ##

Lets check the PDBs:

SQL> show pdbs;

    CON_ID CON_NAME           OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------
     2 PDB$SEED           READ ONLY  NO
     3 PDB21              READ WRITE NO
     4 PDB22              READ WRITE NO

And now, you can see how to create the PDB using DBCA once you have the container ready:

## Command Example ##

/u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca \
-silent \
-createPluggableDatabase \
-sourceDB cdb122 \
-pdbName pdb23 \
-pdbAdminPassword Welcome1



## Output ##

[oracle@rac1-node1 bin]$ /u01/app/oracle/product/12.2.0/dbhome_1/bin/dbca -silent -createPluggableDatabase -sourceDB cdb122 -pdbName pdb23 -pdbAdminPassword Welcome1

     5 PDB23              READ WRITE NO

I think is enough DBCA exploration for now.
Don't get to frustrated after the first initial errors or mistakes... they are just part of the fun (or that is what Trillian keeps telling me..)
