To optimize performance or increase storage capacity for the appliance, you can deploy an external configuration database. You can configure the appliance to connect to DB2®, PostgreSQL, Microsoft® SQL Server, or Oracle database on an external server.
About this task
A Verify Identity Access appliance with Advanced Access Control or Federation includes an internal database to store configuration data.
The appliance provides scripts to deploy the configuration database on an external DB2, PostgreSQL, Microsoft® SQL server, or Oracle server. You can then configure the appliance to use the external database.
The Oracle Compatibility mode in DB2 must be turned off when you are using an external DB2 Configuration Database or HVDB with IBM® Verify Identity Access.
Note: IBM Verify Identity Access uses the configured username as the schema name to connect to the database. Therefore, aliases might need to be created in DB2 in the event that the username does not match the schema name in the database.
Procedure
-
Use the File Downloads management page in the local management interface to access the configuration database deployment files for your environment.
Table 1. Configuration database deployment scripts
| Database type |
Deployment scripts |
| DB2 |
/access_control/database/db2/config/cluster_config_db2.sql |
| PostgreSQL |
/access_control/database/postgresql/config/cluster_config_postgresql.sql |
| Oracle |
/access_control/database/oracle/config/cluster_config_oracle.sql |
| Microsoft® SQL Server |
/access_control/database/mssql/config/cluster_config_mssql.sql |
-
Save the deployment script on the database server.
-
Run the DB2, PostgreSQL, Microsoft® SQL server, or Oracle script to create the external database.
- PostgreSQL script
-
Run the following command:
psql --echo-all --variable ON_ERROR_STOP=1 --file <sql file name>
--username <username> --host <host> --port <port> <database name>
- Oracle script
-
- Copy the downloaded cluster_config_oracle.sql file into the Oracle home directory. For example, ORACLE_HOME=/opt/oracle/app/oracle/product/11.2.0/dbhome_1
- Log in to SQL*Plus.
- At the SQL prompt, run START cluster_config_oracle.sql.
- DB2 script
-
- Create a DB2 instance to contain the configuration database. For information about creating the DB2 instance, see the DB2 documentation.
- Log in to the DB2 Command utility (Windows™) or DB2 host (UNIX™) as the DB2 administrator.
- Run the following command:
db2 -tsvf <fully_qualified_path_to_script>
The following example shows the fully qualified path to the script:
db2 -tsvf /tmp/cluster_config_db2.sql
- Microsoft® SQL server script
-
Run the following command:
sqlcmd -i <sql file name> -U <username> -P <password> -S <host> -d <database name>
-
Validate that the tables were successfully created.
-
Ensure that no errors were returned during the creation and log in to the database to manually check that the tables exist.
-
Populate the database with initial configuration data. Export the embedded configuration database data and then import this data into the external server.
Note: Ensure that data is exported from the appliance and validated. Ensure that this data is also imported into the external server successfully.
-
From the top menu of the local management interface, select System > Cluster Configuration to open the Cluster Configuration management page.
-
Select the Database tab.
-
You must enter the following JDBC connection information:
- Type
- The database type, which is either DB2, PostgreSQL, MSSQL, or Oracle.
- Address
- The IP address of the external database server.
- Port
- The port on which the external database server is listening.
- Username
- The name of the database administrator.
- Password
- The password for the database administrator.
DB2 also requires the following information:
- Secure
- Select this check box to create a secure connection with the server.
Note: Before a secure connection can be established, you must first import the certificate that the appliance uses to communicate with the server into the lmi_trust_store and rt_profile_keys key files. Use the SSL Certificates page to import the appropriate certificate.
- Database name
-
The name of the database instance on the external DB2 server.
Complete the following steps to identify and specify the DB2 database name when your DB2 database is remote to the cluster that you are configuring.
- Open the cluster_config_db2.sql file that was used to create the database and tables.
- In the CREATE DATABASE entry, get the name that is specified. In the following entry,
CONFIG is the string that identifies the default database name:
CREATE DATABASE CONFIG ALIAS CONFIG using codeset UTF-8 territory us
PAGESIZE 8192 WITH "CONFIG Tables";
Note: PAGESIZE 8192 is an example. Adjust according to your requirements.
PostgreSQL also requires the following information:
- Secure
- Select this check box to create a secure connection with the server.
Note: Before a secure connection can be established, you must first import the certificate that the appliance uses to communicate with the server into the lmi_trust_store and rt_profile_keys key files. Use the SSL Certificates page to import the appropriate certificate.
- Database name
- The name of the database instance on the external PostgreSQL server.
Oracle also requires the following information:
- Secure
- Select this check box to create a secure connection with the server.
Note: Before a secure connection can be established, you must first import the certificate that the appliance uses to communicate with the server into the lmi_trust_store and also a keystore which only contains public keys that needs to be created. Use the SSL Certificates page to create this keystore and to import the appropriate certificate
- Certificate Store
- Choose the keystore which contains the certificate that will be used to communicate with the server.
- Service name
- Specify the name of the Oracle instance on the external server. Contact your Oracle database administrator for this information. SID will work but might show a warning in the LMI on saving configuration. This can be ignored.
MSSQL also requires the following information:
- Secure
- Select this check box to create a secure connection with the server.
Note: Before a secure connection can be established, you must first import the certificate that the appliance uses to communicate with the server into the lmi_trust_store and rt_profile_keys key files. Use the SSL Certificates page to import the appropriate certificate.
- Database name
-
The name of the database to connect to.
- Instance name
-
The database instance name to connect to. When it isn't specified, a connection is made to the default instance.
- Trust the server certificate
- Select this check box if the server TLS/SSL certificate should not be validated.
- Windows authentication
- Select this check box to enable Windows (Kerberos) authentication for connections to the SQL server.
- Keytab
- If windows authentication is selected, then the keytab file is used instead of a password for authentication. Keytab files are uploaded using the Kerberos configuration.
-
Click Save.
-
Deploy the changes.
Results
The appliance is configured to use the configuration database that is deployed on the external system.
