Introduction

This hands-on lab demonstrates how to install and manage Oracle Database 12c with Oracle ZFS

Storage Appliance. You’ll learn how to apply Oracle Hybrid Columnar Compression, the Oracle

Intelligent Storage Protocol feature of Oracle ZFS Storage Appliance, the Direct NFS Client feature of

Oracle Database, 12c Container and Pluggable Databases, and more. In addition, you’ll learn how

easy it is to use Oracle ZFS Storage Appliance software to configure services, create and use storage

shares, and monitor database performance with Oracle ZFS Storage Appliance analytics.

This hands-on lab comes with the following components pre-installed:

1. Oracle ZFS Storage Appliance VM Simulator running os8.4

2. Oracle Linux 6.6 VM

3. Oracle Database 12c Release 1 (12.1)

4. Patch 19630940 for OISP Analytics


Provisioning the Oracle ZFS Storage Appliance

Log in to the Browser User Interface

1. Open a web browser by double-clicking on the Firefox icon on the desktop.

2. Enter https://192.168.56.101:215 into web browser window.

3. In web browser, enter oracle as Username and oow as Password, then press the LOGIN button.

https://192.168.56.101:215/


4. The Oracle ZFS Storage Appliance Status Dashboard will be displayed.

Create a Project

A project is a collection of filesystems and LUNs that share the same common settings. By grouping all shares into the same project, the management of the storage becomes simplified.

1. Begin by clicking on Shares on the top toolbar.

2. Click on PROJECTS, then click on the + icon to create a new project.

3. Name the project hol2066.


4. Once the project has been created, edit the hol2066 project by selecting the pencil icon.

5. With the hol2066 project opened, select General at the top to view the project settings.

6. The following changes will need to be made:

a. Mountpoint should be /export/hol2066

b. Update access time on read should be deselected

c. User should be 54321

d. Group should be 54321


7. Click APPLY at the top right.

Create Shares

The database will be stored on the Oracle ZFS Storage Appliance Simulator. There will need to be three shares setup to store the datafiles, redo logs & control files, and fast recovery area.


1. Click on Shares next to General to begin creation. Do not click SHARES on the top toolbar since this

will deselect the current project.

2. Click the + icon to create a new filesystem.

3. Create a share called datafiles and click APPLY.


4. Create a share called fra and click APPLY.

5. Create a share called logs and click APPLY.


You should now have three shares created: datafiles, fra, and logs.

Enable SNMP to activate OISP and HCC

Oracle Intelligent Storage Protocol (OISP) is a unique file storage protocol for Oracle Database 12c and Oracle ZFS

Storage Appliance that allows storage to have database awareness. Oracle Intelligent Storage Protocol enables

continuous communication between database and storage, automatically and dynamically optimizing critical tuning

parameters in real time.

Oracle Intelligent Storage Protocol is available exclusively with the combination of Oracle Database 12c and the

Oracle ZFS Storage Appliance because it requires the intelligence on both the database host side and the storage

side to pass and interpret cues from the database. With Oracle Intelligent Storage Protocol, Oracle Database can

send over 70 different cues, which Oracle ZFS Storage Appliance categorizes into 5 different groups. The different

database file types can now be differentiated by the Oracle ZFS Storage Appliance. Oracle Intelligent Storage

Protocol dynamically and automatically adjusts share parameter settings to tune the storage system for optimal

database performance on the fly. Traditionally, multiple shares would have to be set up for different database file

types, each with its own settings all tuned manually by an administrator. But with Oracle Intelligent Storage Protocol

and the Oracle ZFS Storage Appliance, the entire process is automated.

Hybrid Columnar Compression (HCC) is an Oracle Database compression technology which enables the highest

levels of data compression and provides enterprises with cost savings and performance improvements due to

reduced I/O. Average storage savings can range from 6x to 15x, depending on which Hybrid Columnar

Compression level is implemented. Hybrid Columnar Compression gives database administrators the flexibility to

select from four different levels of Data Warehouse or Archive compression to balance storage savings and I/O

reduction with CPU resource utilization. Hybrid Columnar Compression can be enabled on Oracle Databases

residing on dNFS shares without ASM on an Oracle ZFS Storage Appliance beginning with Oracle Database

Enterprise Edition 11.2.0.3.

Oracle Intelligent Storage Protocol and Hybrid Columnar Compression both rely on SNMP to establish the initial

relationship between Oracle Database 12c and Oracle ZFS Storage Appliance.

1. Navigate to Configuration Services.


2. Click on SNMP underneath System Settings.

3. The following settings should be set:

a. Version: v1/2c

b. Community name: public

c. Authorized network/mask: 0.0.0.0 / 0

d. Appliance contact: HOL

e. Trap destinations: 127.0.0.1


4. Click the power-on button to enable the SNMP service.

5. Verify the SNMP LED turns on (green).


Provisioning Oracle Linux

The binaries for Oracle Database 12c have already been preinstalled on the Oracle Linux VM. They are held in the /u01/app/oracle directory.

Note: the password for this VM is oow.

Terminal

Open a new terminal session by double-clicking on the Terminal icon on the desktop:

Create a Directory Structure

Each of the shares created on the storage will need a local directory to contain the mounts on the Oracle Linux VM. Please use the following locations:

$ sudo mkdir -p /zfssa/hol2066/datafiles

$ sudo mkdir -p /zfssa/hol2066/fra

$ sudo mkdir -p /zfssa/hol2066/logs

Edit /etc/fstab for the New Shares

The entries have already been populated inside of /etc/fstab:

$ cat /etc/fstab

192.168.56.101:/export/hol2066/datafiles /zfssa/hol2066/datafiles nfs

rw,bg,hard,nointr,rsize=1048576,wsize=1048576,tcp,vers=3,timeo=600,noac 0 0

192.168.56.101:/export/hol2066/fra /zfssa/hol2066/fra nfs


192.168.56.101:/export/hol2066/logs /zfssa/hol2066/logs nfs


Mount the Shares

$ sudo mount -a

Enable dNFS

The entries have already been populated inside of $ORACLE_HOME/dbs/oranfstab:

$ cat $ORACLE_HOME/dbs/oranfstab

server: 192.168.56.101

path: 192.168.56.101

nfs_version: nfsv4

export: /export/hol2066/datafiles mount: /zfssa/hol2066/datafiles

export: /export/hol2066/fra mount: /zfssa/hol2066/fra

export: /export/hol2066/logs mount: /zfssa/hol2066/logs

Direct NFS, also known as dNFS, is the preferred method for database communication with the Oracle ZFS Storage Appliance. This feature optimizes I/O traffic by replacing the kernel NFS with an NFS client that is tailored specifically for Oracle software. It is only available in Oracle Database 11g and 12c.


$ cd $ORACLE_HOME/rdbms/lib

$ make –f ins_rdbms.mk dnfs_on

rm -f /u01/app/oracle/product/12.1.0/dbhome_1/lib/libodm12.so; cp

/u01/app/oracle/product/12.1.0/dbhome_1/lib/libnfsodm12.so

/u01/app/oracle/product/12.1.0/dbhome_1/lib/libodm12.so


Create a Database

Use DBCA to Create a Database

DBCA, the Database Configuration Assistant, is a tool to create, configure, or destroy an Oracle database. It will be utilized in this lab in order to facilitate a database install.

1. Launch dbca from the terminal.

$ dbca

2. In the new window that opens, select Create Database and click Next.


3. Click on Advanced Mode and click Next.


4. Select General Purpose or Transaction Processing and click Next.


5. Enter hol2066 for Global Database Name and hol2066 for SID. Click Next.


6. Deselect Configure Enterprise Manager (EM) Database Express and click Next. Enterprise

Manager is not necessary for this lab.


7. Select Use the Same Administrative Password for All Accounts. Enter oow into both

password fields. Click Next.


8. Click Next on the following screen.


9. Configure to use the NFS shares:

a. Select Use Common Location for All Database Files. Type

/zfssa/hol2066/datafiles into the File Location field.

b. Select Use Oracle-Managed Files.

c. Select Specify Fast Recovery Area. Type /zfssa/hol2066/fra into the Fast

Recovery Area field.

10. Click Multiplex Redo Logs and Control Files. Type /zfssa/hol2066/logs into the first

input field. Click OK to close the window. Click Next.


14. Click Finish on the following screen.


15. The database will begin the creation process. No action is needed here.


Monitor Progress and Performance Using Oracle ZFS Storage Analytics

Analytics is an advanced facility that you can use to graph a variety of statistics in real-time and record this data for later viewing. It has been designed for both long term monitoring and short term analysis. When needed, it makes use of DTrace to dynamically create custom statistics, which allows different layers of the operating system stack to be analyzed in detail.

Navigate to the Analytics section

While the database is installing, click on the Analytics tab on the right side of the upper taskbar.

Add a Statistic

On the left side of the browser, click on the + icon next to Add statistic to bring up the statistic menu.

The most relevant statistics for database performance analysis can be found in the NFSv4 category. Select ‘Broken down by Application ID.’

Analytics has been designed around an effective performance analysis technique called drill-down analysis. This involves checking high level statistics first, and to focus on finer details based on findings so far. This allows you to quickly narrow the focus to the most likely areas.


After the database has been created, click on Close.


Create a Tablespace with HCC

1. Change the ORACLE_SID to hol2066, then use SQL*PLUS to interface with the Oracle 12c Database.

$ export ORACLE_SID=hol2066

$ sqlplus / as sysdba
