Essbase “Virtual Cube” BSO Tuning
An Essbase “virtual cube” is a specific design setup where transparent partitioning is used and consists of multiple source databases that are partitioned to a single target Block Storage (BSO) database. The single target BSO database is empty meaning contains no data. The purpose of this design setup is so that end users have one consolidated BSO cube for reporting. In some cases, the target BSO database may have different dynamic calc member formulas then the source databases. Also, the target BSO database may have more dimensions to accommodate the source databases and may have different sparse/dense configuration since source databases are tuned with data accordingly.
The Essbase Database Administration Guide mentions how to tune Essbase BSO databases that contains data; however, there is no documentation on how to tune a BSO database that contains no data like in a “virtual cube” setup.[Read More]
