This chapter provides an overview of installing a supported database for use with Oracle Communications Services Gatekeeper.
Although there are substantial differences between the installation procedures for each type of database, all installation types include the following basic steps:
Installing the database software.
Setting up a user account that Services Gatekeeper uses to access the database.
Granting the user account appropriate privileges on the database.
See the following sections for information about the database you are installing:
Follow these instructions if you are using Oracle Real Application Clusters (Oracle RAC) or Oracle Database Single Instance database software.
The database must be installed on a dedicated server running outside the Services Gatekeeper cluster.
Oracle RAC or MySQL are supported production environments that require high availability.
For information about using Oracle WebLogic Server with multiple data sources, see Oracle Fusion Middleware Administering JDBC Data Sources for Oracle WebLogic Server.
To install the database software:
Follow the instructions in the database installation guide, available in the installing and upgrading section on the Oracle Database Documentation Library website.
During the installation process, select these configuration options:
Create the database using the Transaction Processing template.
Use the Dedicated Server Mode for the database.
Change the processes parameter to be equal to:
[(wlng.datasource MaximumCapacity + wlng.localTX.datasource MaximumCapacity) * NumberOfServers]
where NumberOfServers is the number of Services Gatekeeper servers in the cluster. MaximumCapacity is a parameter in the connection pool settings for the JDBC data sources. Normally this value is 150 for both data sources, but you may need to increase it.
Download and install the latest Oracle database patch set.
Continue to "Setting Up a Services Gatekeeper User for the Oracle Database".
To set up a Services Gatekeeper user for the Oracle database:
Create a database user for Services Gatekeeper with an allowed (unlimited) quota on its default tablespace (the users tablespace). The user name and password for the user are later copied to each Services Gatekeeper server.
Grant the user the following privileges:
CREATE SESSION
CREATE TABLE
Continue to "Installing Services Gatekeeper".
Follow the instructions in this section if you are using Oracle Express Edition (XE) as your database.
Oracle XE can be installed either on a server in the Services Gatekeeper cluster or on a separate server. If it is installed in the cluster, it should be in the same server as the Network Tier.
Note:
Oracle XE is recommended over MySQL for Services Gatekeeper development installations because the Oracle XE schema is compatible with enterprise Oracle databases. Neither Oracle XE nor MySQL is recommended for production deployment.To install Oracle XE:
Download the Oracle Database Express Edition installer from the Oracle Technology Network website:
Follow the instructions to select and download the Oracle Database Express Edition software for your operating system.
Install Oracle XE using the instructions in the installation guide on the Oracle documentation website at:
Continue to "Configuring Oracle XE for Services Gatekeeper".
To configure Oracle XE for Services Gatekeeper:
Open a command window.
(Linux only) If the required environment variables are not already set, do the following:
For Bash, Bourne, or Korn shell, enter the following command:
source ORACLE_HOME/bin/oracle_env.sh
For C shell, enter the following command:
source ORACLE_HOME/bin/oracle_env.csh
Enter the following command:
sqlplus /nolog
Connect to the database (on Windows you are prompted for the user name and password):
SQL> connect SYSTEM/SYSTEM_user_password@XE
Enter the following command to increase the number of allowable JDBC connections:
SQL> alter system set processes=300 scope=spfile;
Create a Services Gatekeeper user and password using the following command:
SQL> create user database_username identified by password;
Grant the newly created user privileges using the following command:
SQL> grant create session, create table, resource to database_username;
Exit SQL*Plus:
SQL> exit
Restart the database for the changes to take effect.
Continue to "Installing Services Gatekeeper".
Follow the instructions in this section if you are using MySQL as your database. Services Gatekeeper supports using single instance and clustered MySQL database implementations.
MySQL can be installed either on a server in the Services Gatekeeper cluster or on a separate server. If it is installed in the cluster, it should be in the same server as the Network Tier.
Note:
Oracle XE is preferable to MySQL for Services Gatekeeper development installations because the Oracle XE schema is compatible with enterprise Oracle databases. Oracle XE is not recommended for production deployment.This section covers the following topics:
To install a MySQL database:
Download the MySQL database software from the Oracle software delivery website at:
Follow the instructions in the MySQL documentation for installing MySQL. The documentation is available on the MySQL website at:
When installing MySQL:
Linux: For most Linux distributions, you can use a package manager such as dpkg or YUM.
Windows: Unless you have additional special requirements, you can select the Developer Default installation option.
Continue to one of the following sections:
This section summarizes the commands required to configure MySQL on most versions of Linux. Command locations may differ between Linux distributions.
To configure MySQL on Linux:
As the user root, start the MySQL database:
/etc/rc.d/init.d/mysqld start
Open the /etc/my.cnf file and do the following:
Edit the connection variable so that max_connections is equal to:
[(wlng.datasource MaximumCapacity + wlng.localTX.datasource MaximumCapacity) * NumberOfServers]
where NumberOfServers is the number of Services Gatekeeper servers in the cluster. MaximumCapacity is a parameter in the connection pool settings for the JDBC data sources. Normally this value is 150 for both data sources, but you may need to increase it.
[mysqld] max_connections=400
Add an entry for the default character set. The recommended character set is Latin1.
default-character-set=latin1
Save and close the file.
Restart MySQL:
/etc/rc.d/init.d/mysqld stop /etc/rc.d/init.d/mysqld start
Continue to "Creating the Database and a Database User".
To configure MySQL on Windows:
From a text editor, open the my.ini file and do the following:
Edit the connection variable so that max_connections is equal to:
[(wlng.datasource MaximumCapacity + wlng.localTX.datasource MaximumCapacity) * NumberOfServers]
where NumberOfServers is the number of Services Gatekeeper servers in the cluster. MaximumCapacity is a parameter in the connection pool settings for the JDBC data sources. Normally this value is 150 for both data sources, but you may need to increase it.
[mysqld] max_connections=400
Add an entry for the default character set. The recommended character set is Latin1.
default-character-set=latin1
Save and close the file.
Continue to "Creating the Database and a Database User".
To configure MySQL for Services Gatekeeper, perform the following for each IP address in the cluster:
Create the Services Gatekeeper database user and password.
You will need to provide this user name and password when you configure the Services Gatekeeper domain. For information about the various command-level modes of accessing the MySQL server, see the documentation on the MySQL website.
Grant access privileges:
GRANT ALL ON *.* TO database_username@ip_address IDENTIFIED BY user_password
Create the database for Services Gatekeeper:
CREATE DATABASE database_name
You will need to provide the database name when you configure the Services Gatekeeper domain.
Continue to "Installing Services Gatekeeper".
Follow the instructions in this section if you are using MySQL Cluster Carrier Grade Edition (CGE) as your database. Services Gatekeeper supports using single instance and clustered MySQL database implementations.
MySQL can be installed either on a server in the Services Gatekeeper cluster or on a separate server. If it is installed in the cluster, it should be in the same server as the Network Tier.
To install MySQL Cluster SGE software:
Download a supported version of MySQL Cluster from the Oracle software delivery website:
Install the MySQL Cluster CGE software using the instructions in the installation guide on the Oracle documentation website:
For a first Cluster, start with a single MySQL Server (mysqld), a pair of Data Nodes (ndbd) and a single management node(ndb_mgmd) – all running on the same server. Using the management server node, you can start and stop other nodes, configure data, run backup, and perform other tasks.
To configure the management server node:
Create the config.ini file on the management server, under the /var/lib/mysql-cluster/ directory.
The following is an example of the ndbd default section in the config.ini file. For the hostname parameter, host_name_or_IP_address represents the host name or IP address of the node. For example:
hostname=node1.example.com
The system values in this example are suggested values. The values you use will depend on how your system is set up.
Example ndbd default section of the config.ini file:
[ndbd default] NoOfReplicas=2 DataMemory=4G IndexMemory=400M MaxNoOfAttributes=500000 MaxNoOfTables=1760 MaxNoOfOrderedIndexes=3000 MaxNoOfUniqueHashIndexes=1250 MaxNoOfConcurrentOperations=100000 [ndb_mgmd] NodeId=1 hostname=host_name_or_IP_address datadir=/var/lib/mysql-cluster/ [ndbd] NodeId=2 hostname=host_name_or_IP_address datadir=/usr/local/mysql/data/ [ndbd] NodeId=3 hostname=host_name_or_IP_address datadir=/usr/local/mysql/data/ [mysqld] NodeId=4 hostname=host_name_or_IP_address [mysqld] NodeId=5 hostname=host_name_or_IP_address [mysqld] [mysqld]
Create the my.cnf file under the /etc directory, using the following values:
[mysqld] ndbcluster datadir=/usr/local/mysql/data basedir=/usr/local/mysql user = mysql port = 3306 default-storage-engine=ndb ndb-connectstring= host_name_or_IP_address [mysql_cluster] ndb-connectstring= host_name_or_IP_address
To start the MySQL Cluster processes:
Enter the following commands in order:
./ndb_mgmd -f /var/lib/mysql-cluster/config.ini ./ndbd mysqld_safe--ndb_nodeid=4 --user=mysql&
After you run these commands, the ndb_mgm prompt appears.
Check the status of the cluster by entering the following command:
ndb_mgm> show
The status of the cluster is displayed on the command line. For example:
Connected to Management Server at: 12.345.67.81:1186 Cluster Configuration --------------------- [ndbd(NDB)] 2 node(s) id=2 @12.345.67.82 (mysql-5.5.30 ndb-7.2.12, Nodegroup: 0, Master) id=3 @12.345.67.83 (mysql-5.5.30 ndb-7.2.12, Nodegroup: 1) [ndb_mgmd(MGM)] 1 node(s) id=1 @12.345.67.82 (mysql-5.5.30 ndb-7.2.12) [mysqld(API)] 3 node(s) id=4 @12.345.67.82 (mysql-5.5.30 ndb-7.2.12) id=5 @12.345.67.83 (mysql-5.5.30 ndb-7.2.12) id=6 (not connected, accepting connect from any host)
Wait for the data nodes to finish starting.
Start your MySQL server.
