Managing the database server configuration
Use the Database Server Configuration page to configure, reconfigure, or unconfigure the database server for the IBM® Security Identity Governance and Intelligence virtual appliance.
About this task
- In a cluster environment, all nodes must use the same database. In that environment, reconfiguring, and unconfiguring can be done from the primary node only.
For Oracle, if you change the version of the LMI security protocol, and consequently also the TLS version on the Oracle database server, you must reconfigure Database Server Configuration before users can log in to Identity Governance and Intelligence again.
- An embedded PostgreSQL database environment requires higher resource consumption
than the standard external DB2 database, making it critical to increase memory and CPU allocation to
ensure a stable operation of the environment. When the database is co-resident in the VA, the CPU
and memory resources will be taxed additionally to provide services to the Identity Governance
processes, as well as the database management processes. In laboratory tests, the CPU requirements
on the VA are 2 to 3 times higher when running with PostgreSQL, versus the combined requirements of
a VA and DB running with DB2. The additional memory and CPU requirements are most important in the
PostgreSQL cluster scenario when data replication is enabled. Despite additional memory and CPU, the
performance of this environment also falls behind that of DB2.
At this time, PostgreSQL is not recommended for mission-critical environments, or deployments where performance requirements are high.

If you select Oracle (Standard) or Oracle (Custom),
configure these options.
Note: When you select Oracle (Custom) as the database type, you cannot
configure these options:
Note: If you want to manage FIPS features with Oracle, you must
be compliant with TLSv1.2 protocol (see LMI security
protocol).

Reconfigure | Note: Reconfiguration does not update the database schema. It configures IBM Security Identity Governance and Intelligence with new database details.
If you select Oracle (Standard) or Oracle (Custom),
configure these options.
