Oracle REST Data Service

Oracle Cloud Infrastructure Storage Software Appliance – Installation and Configuration

Author: Martin Berger 8. November 2017

The Oracle Cloud Infrastructure Storage Software Appliance – also known as Oracle Storage Cloud Software Appliance OSCSA – acts as a gateway between classic storage and the Oracle Cloud Infrastructure Object Storage Service. The appliance can be installed on an on-premises Linux system or in an Oracle Compute Cloud machine and runs in a Docker container. It offers a local cache where clients can place their files before the OSCSA moves them into the Storage Service. The communication between a client with a filesystem to the OSCSA works with NFSv4, from the OSCSA to the Object Storage Service, Oracle is using their REST interface. Traffic from the OSCSA to and from the Oracle cloud can be encrypted and compressed.

In this blog post first I will show you how you can install and configure the OSCSA in an on-premises environment. In a second step I configure an on-premises database server which uses the Object Storage Service as Oracle RMAN backup location.

Key Features

Compression and Exncryption
File Versioning
End-to-end Data Integrity with Checksum Verification
Support for Data Archival (Oracle Storage Archive Class)
Pin files to the appliance cache for faster access

Where to get the OSCSA and more Information

Requirements

Two dual-core CPUs (4-core CPUs recommended)
Minimum memory requirements (based on the maximum number of files that can be uploaded to the appliance filesystem):
- 16 GB for filesystems up to 1 million files
- 32 GB for filesystems up to 5 million files
- 64 GB for filesystems up to 10 million file
Minimum disk size required to install Docker: 10 GB
Oracle Linux 7 with UEK Release 4 or later
Docker 1.12.6
NFS version 4.0

The installation and configuration of the required Oracle Linux components OL7 with UEK4, Docker and NFS is very well described in the “Using Oracle…” guide. Please take a look in the guide, it’s straight forward. The OSCSA installer does not start when the requirements are not fullfilled.

My Test Environment

OSCSA	breitenbach.martinberger.local	Oracle Linux 7.4	100GB Storage
Database Server	zuchwil.martinberger.local	Oracle Linux 7.4	Oracle RDBMS 12.1.0.2
Traditional Cloud Account	cloud.oracle.com	Zone EM2	Oracle Cloud Infrastructure Object Storage Classic

Firewall

Port 32771 (Appliance Web Interface) , 32772 (NFS) and 32773 (REST) have to be opened on the appliance machine. If you don’t want to use these port numbers, you can set them during the installation process. Execute as user root:

# firewall-cmd --permanent --zone=public --add-port=32771/tcp
# firewall-cmd --permanent --zone=public --add-port=32772/tcp
# firewall-cmd --permanent --zone=public --add-port=32772/tcp
# firewall-cmd --reload

# firewall-cmd --permanent --zone=public --add-port=32771/tcp

# firewall-cmd --permanent --zone=public --add-port=32772/tcp

# firewall-cmd --reload

File Content

All installation steps are executed as OS user root. The Oracle Storage Cloud Software Appliance Software Release 16.3.1.3 is available on my local machine in folder /stage. The extracted OSCSA file contains a file called OSCSA_GATEWAY_README.txt where you can get more information about the installation and configuration possibilities like proxy etc.

Installation

The installation starts by executing oscsa-install.sh. I have added the parameter -a = advanced so I am able to set ports for NFS, Administrative Web Interface and REST. Oracle recommends for the cache storage a minimal size. I have ignored that for my test environment.

If you have already configured an OSCSA FileSystem via the Management Console,

you can access the NFS share using the following port.

NFS Port: 32772

Example: mount -t nfs -o vers=4,port=32772 breitenbach.martinberger.local:/<OSCSA FileSystem name> /local_mount_point

Configure a OSCSA FileSystem in the Appliance Web Interface

In this step, the OSCSA will be connected to the Oracle Cloud. At the moment, no <OSCSA FileSystem name> is configured. An OSCSA filesystem is like a namespace containing a set of data. Now we can log in into the Appliance Web Interface to create our first Object Storage filesystem. URL for the interface is https://<servername>:<port>. The port for the interface was set during the installation process.

For the connection to the cloud, you need to know your Identity Domain, Username, Password and REST Storage Endpoint URL. The FileSystem name will be reused later for the NFS mount.

Create a FileSystem called OCIClassicStorage01

Enter Domain, Username, Password and REST Storage Endpoint URL. Below this screenshot you can see where you find the URL in your Traditional Cloud Account.

Here you can see the REST URL.

Click on Validate

If the account informations are verified, you are able to enable compression and encryption. I have enable encryption here. Click Save.

The OSCSA storage is now ready to synchronize with the cloud. Click Connect.

Now you can see the the connection between the Oracle Storage Cloud Software Appliance and the Oracle Cloud Infrastructure Object Storage Service is ready.

In the Traditonal Cloud Account in the Storage Classic dashboard is a new object storage filesystem available.

Connect the Database Server to the Oracle Storage Cloud Software Appliance

Let’s connect the database server to the OSCSA to store data in the Object Storage Service. First we check again on the OSCSA server if the service is running.

# oscsa info
Management Console: https://breitenbach.martinberger.local:32771
If you have already configured an OSCSA FileSystem via the Management Console,
you can access the NFS share using the following port.

# oscsa info

Management Console: https://breitenbach.martinberger.local:32771

If you have already configured an OSCSA FileSystem via the Management Console,

you can access the NFS share using the following port.

On the database server a new mountpoint will be created.

# mkdir /mnt/oscsa

1	# mkdir /mnt/oscsa

We mount the OSCSA with NFS v4 to the local server. This entry can be added later to autofs or whatever you use to automatically mount an NFS filesystem. Permission of the mountpoint is drwxrwxrwx – so everybody can write into it at the moment.

# mount -t nfs -o vers=4,port=32772 breitenbach.martinberger.local:/OCIClassicStorage01 /mnt/oscsa

1	# mount -t nfs -o vers=4,port=32772 breitenbach.martinberger.local:/OCIClassicStorage01 /mnt/oscsa

Check.

# df -m | grep oscsa
breitenbach.martinberger.local:/OCIClassicStorage01 52428800 1 52428800 1% /mnt/oscsa

1 2	# df -m \| grep oscsa breitenbach.martinberger.local:/OCIClassicStorage01 52428800 1 52428800 1% /mnt/oscsa

Execute an Oracle RMAN Backup to the Cloud

A new subdirectory on the NFS mountpoint will be created.

# mkdir -p /mnt/oscsa/backup/JSF01

1	# mkdir -p /mnt/oscsa/backup/JSF01

Start Oracle Recovery Manager RMAN database backup.

$ rman target=/

$ rman target=/

RMAN> BACKUP AS BACKUPSET DATABASE PLUS ARCHIVELOG FORMAT '/mnt/oscsa/backup/JSF01/backupsetJSF01%U.bkp';

The backup files are created locally in the specified mountpoint directory.

At the moment where the backup sets are arrived on the mountpoint, the OSCSA begins to encrypt (this was my selections during filesystem creation) and transfer them into the Oracle Cloud. This is visible in the Appliance Web Interface.

Now the files are uploaded into the Oracle Cloud. This can be verified in the Traditional Cloud Account in the specific filesystem. The files are encrypted and have file names like 10101-v1, 10103-v1 etc.

Anything else?

Sure, this was just a basic overview how to configure the on-premises Oracle Storage Cloud Software Appliance. There are many more features like retrieve data, cloud access via command line, preserve filesystem cache, create directory permissions, set user permissons, monitor the appliance, backup the appliance, encryption key handling, use the archive storage and so on which are worth to spend more time for investigation in the future.

Summary

The Oracle Storage Cloud Software Appliance is a nice piece of software which helps you to use the Oracle Cloud Infrastructure Object Storage Service. The appliance is easy to install and configure, local encryption is possible and the documentation is very good. Database Backups and Database Export a perfect candidates for this service. The price is hot, $0.0204 per GB for the first TB, and $0.0201 per GB for the next 49TB.

Thumbs up!

Oracle Cloud, Oracle Linux, Oracle REST Data Service

Install and Configure Oracle Application Express with Oracle REST Data Services and Apache Tomcat

Author: Martin Berger 9. May 2017

In this article I will show you how you can install and configure Oracle Application Express (APEX) and the Oracle REST Data Service (ORDS), which is running on an Apache Tomcat application server. In previous installations I used the Oracle HTTP server and the extenstion mod_plsq. But this does not work anymore with the newest Oracle HTTP server version. In the Oracle Application Express Installation Guide is written:

mod_plsql is deprecated as of Oracle HTTP Server 12c (12.1.3). For more information, please see My Oracle Support Note 1576588.1. Oracle recommends using Oracle REST Data Services instead.

Oracle REST Data Service is the future – so let’s go to the future.

Installation Steps

Installation and Configuration Oracle Application Express 5.1.1
Installation and Configuration Apache Tomcat 8.5.14
Installation and Configuration Oracle Rest Data Service ORDS 3.0.9

My new architecture what I want to build looks like as described on this picture.

Source: http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-deploy-installation-1878444.html

My Environment

Red Hat Enterprise Linux Server Release 7.3 – server hostname is neuendorf.jurasuedfuss.coom
Oracle Database 12c Standard Edition Release 12.2.0.1.0 – database service name is APEXORDS.jurasuedfuss.com
OS Firewall is open for Port 8080

OS Users

I work with two OS users to separate RDBMS and application tasks:

oracle – Oracle RDBMS / Listener / Oracle Application Express
tomcat – Apache Tomcat / ORDS / Java Development Kit JDK 1.8

Directories

Oracle Software: /u01/app/oracle
Apache Tomcat / ORDS / JDK: /u01/app/tomcat

1. Installation and Configuration Oracle Application Express 5.1.1 – OS User: oracle

I have downloaded Oracle Application Express here: http://www.oracle.com/technetwork/developer-tools/apex/downloads/download-085147.html . The extracted software is located on the server in the /tmp directory. For the APEX data I have created a new tablespace called APEX too.

Go to the software location:

[oracle@neuendorf ~]$ cd /tmp/apex

1	[oracle@neuendorf ~]$ cd /tmp/apex

[oracle@neuendorf ~]$ . oraenv
ORACLE_SID = [oracle] ? APEXORDS
The Oracle base has been set to /u01/app/oracle

[oracle@neuendorf ~]$ sqlplus / as sysdba

[oracle@neuendorf ~]$ . oraenv

ORACLE_SID = [oracle] ? APEXORDS

The Oracle base has been set to /u01/app/oracle

[oracle@neuendorf ~]$ sqlplus / as sysdba

Execute the installation script:

SQL> @apexins apex apex temp /i/

1	SQL> @apexins apex apex temp /i/

Set password for ADMIN user / Workspace INTERNAL:

SQL> @apxchpwd.sql

1	SQL> @apxchpwd.sql

Configure database RESTful services – the passwords for the new created users APEX_LISTENER and APEX_REST_PUBLIC_USER will be used later for the ORDS setup:

SQL> @apex_rest_config.sql

1	SQL> @apex_rest_config.sql

Set password for the APEX_PUBLIC_USER and unlock the account:

SQL> ALTER USER apex_public_user IDENTIFIED BY  <MY_APEX_PUBLIC_USER_PASSWORD> ACCOUNT UNLOCK;

1	SQL> ALTER USER apex_public_user IDENTIFIED BY <MY_APEX_PUBLIC_USER_PASSWORD> ACCOUNT UNLOCK;

To avoid the password expiration for the APEX_PUBLIC_USER, I have created a new profile especially for this user with unlimited password lifetime:

SQL> CREATE PROFILE upd_password_life_time_unlimited LIMIT PASSWORD_LIFE_TIME UNLIMITED;
SQL> ALTER USER apex_public_user PROFILE upd_password_life_time_unlimited;

1 2	SQL> CREATE PROFILE upd_password_life_time_unlimited LIMIT PASSWORD_LIFE_TIME UNLIMITED; SQL> ALTER USER apex_public_user PROFILE upd_password_life_time_unlimited;

Allow other hosts than the localhost to use the Oracle Application Express installation:

SQL> BEGIN
2     DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE(
3          host => '*',
4          ace => xs$ace_type(privilege_list => xs$name_list('connect'),
5          principal_name => 'apex_050100',
6          principal_type => xs_acl.ptype_db));
7 END;
8 /

SQL> BEGIN

2 DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE(

3 host => '*',

4 ace => xs$ace_type(privilege_list => xs$name_list('connect'),

5 principal_name => 'apex_050100',

6 principal_type => xs_acl.ptype_db));

7 END;

8 /

2. Installation and Configuration Apache Tomcat 8.5.14 – OS User: tomcat

Create directory :

[tomcat@neuendorf ~]$ mkdir /u01/app/tomcat

1	[tomcat@neuendorf ~]$ mkdir /u01/app/tomcat

Go to directory and extract software form /tmp:

[tomcat@neuendorf ~]$ cd /u01/app/tomcat/
[tomcat@neuendorf ~]$ tar xvfz /tmp/jdk-8u131-linux-x64.tar.gz
[tomcat@neuendorf ~]$ tar xvfz /tmp/apache-tomcat-8.5.14.tar.gz

[tomcat@neuendorf ~]$ cd /u01/app/tomcat/

[tomcat@neuendorf ~]$ tar xvfz /tmp/jdk-8u131-linux-x64.tar.gz

[tomcat@neuendorf ~]$ tar xvfz /tmp/apache-tomcat-8.5.14.tar.gz

Two new directories for Apache Tomcat and JDK are created:

[tomcat@neuendorf tomcat]$ ll
total 8
drwxrwxr-x. 9 tomcat tomcat 4096 May 9 12:29 apache-tomcat-8.5.14
drwxr-xr-x. 8 tomcat tomcat 4096 Mar 15 09:35 jdk1.8.0_131

[tomcat@neuendorf tomcat]$ ll

total 8

drwxrwxr-x. 9 tomcat tomcat 4096 May 9 12:29 apache-tomcat-8.5.14

drwxr-xr-x. 8 tomcat tomcat 4096 Mar 15 09:35 jdk1.8.0_131

To simplify the management with the Apache Tomcat application server, I have added environment variables to the .bash_profile:

# Tomcat Environment Variables
JAVA_HOME=/u01/app/tomcat/jdk1.8.0_131
CATALINA_HOME=/u01/app/tomcat/apache-tomcat-8.5.14
CATALINA_BASE=$CATALINA_HOME

export JAVA_HOME
export CATALINA_HOME

Startup Tomcat – after the re-login as OS user tomcat the application server can be started by using the environment variable $CATALINA_HOME.

[tomcat@neuendorf ~]$ $CATALINA_HOME/bin/startup.sh
Using CATALINA_BASE: /u01/app/tomcat/apache-tomcat-8.5.14
Using CATALINA_HOME: /u01/app/tomcat/apache-tomcat-8.5.14

Tomcat started.

Verify on command line level if tomcat has started, for example with CURL – HTTP 200 means that the response is OK:

[tomcat@neuendorf tomcat]$ curl -I http://localhost:8080
HTTP/1.1 200
Content-Type: text/html;charset=UTF-8
Transfer-Encoding: chunked

Shutdown Tomcat:

[tomcat@neuendorf ~]$ $CATALINA_HOME/bin/shutdown.sh

1	[tomcat@neuendorf ~]$ $CATALINA_HOME/bin/shutdown.sh

Start- / Stop Runlevel Script:

To automate the start/stop – we use a runlevel script. The script has to be created as OS user root. In one of the first lines, I have set a sleep command to be sure that the database is available before the application server starts.

[root@neuendorf ~]# vi /etc/init.d/tomcat

1	[root@neuendorf ~]# vi /etc/init.d/tomcat

sleep 20

RETVAL=$?
CATALINA_HOME="/u01/app/tomcat/apache-tomcat-8.5.14"

case "$1" in

exit $RETVAL

Add the script to the runlevel environment level 3 and 5:

[root@neuendorf ~]# chmod 755 /etc/init.d/tomcat

1	[root@neuendorf ~]# chmod 755 /etc/init.d/tomcat

[root@neuendorf ~]# cd /etc/rc3.d

Install Oracle REST Database Service ORDS:

You will be asked for a new password for the database user ORDS_PUBLIC_USER (user will be created by this script), for the already existing users APEX_LISTENER and APEX_REST_PUBLIC_USER and for the SYS password. For ORDS metadata, I have created a new tablespace called ORDS.

The values for database server, hostname and the service name are taken from the configuration file ords_params.properties. Do not start ORDS in standalone mode at the end of the configuration.
