ARS_DB2_DATABASE_PATH parameter
If you are configuring the library server and you set the ARS_DB_ENGINE parameter to DB2 (the default), the base file system in which the Content Manager OnDemand database will reside.
You must make sure that the specified location contains
enough space to hold the system tables, the USERSPACE1 table space,
and any application group tables that are not stored in their own
table spaces. The IBM Content Manager OnDemand for Multiplatforms:
Introduction and Planning Guide can help you estimate the amount
of space required to hold the database. The default value is /arsdb.
The ARS_DB2_DATABASE_PATH parameter is ignored
on object servers.
