The following example shows a typical SAP MaxDB resource hierarchy:

The dependencies in the above example correspond to the following protected resources:

Resource
SAP MaxDB Software Component
LKIP.EXAMPLE.COM protects the switchable IP address used for client connections
sapdb_EXAMPLE /data protects the database data device space for the EXAMPLE database
sapdb_ EXAMPLE /log protects the database log device space for the EXAMPLE database
sapdb_ EXAMPLE /rundirectory protects the database RUNDIRECTORY for the EXAMPLE database
sapdb_ EXAMPLE /sys protects the database system device space for the EXAMPLE database
sapdb_lk/data protects the independent data path
sapdb_lk/dep protects the dependent path
sapdb_lk/prog protects the independent program path

In the event of failover, SPS will bring the file system, IP address and database resources (including all the resource dependencies) in service on a backup server. Clients will be disconnected and will need to re-connect to the server. Any SQL statement that has not been committed will need to be re-entered.
