BI-Beans: getcursor error

Question

I have a cube with 10 dimensions and 1 measures with about 16K records.
When I tried to open this cube with BI-Beans, I got this following error message:
oracle.express.ExpressServerExceptionError class: OLAPI
Server error descriptions:
DPR: Unable to execute the query, Generic at TxsOqCursorManager::fetchInitialBlocks
OES: ORA-04031: unable to allocate 16 bytes of shared memory ("shared pool","SELECT /*+ INDEX_COMBINE(V7...","Typecheck heap","kkqgAllocEle.5")
, Generic at TxsRdbOCIConnection::execStmt
     oracle.express.olapi.data.CursorBlock oracle.express.olapi.data.full.FullCursorBlockFetcher.fetchAnyCursorBlock(oracle.olapi.data.cursor.CursorInput[])
Can you guys help me how to solve this problem ??

Answer 1

This is not really a BI Beans error, but happens because the database gets low on memory due to the complexity of the generated SQL.
Try the following OLAP optimization in the init.ora file.
init.ora Parameters
Modify the standard init.ora file (named initsid.ora, located oracle_home/admin/sid/pfile) by setting or adding the parameters described below. When starting the database for an initial build or major data update
operation, use this specifically modified parameters file with a command such as this:
startup pfile = filepath
Make the following changes to the parameters file:
db_cache_size=n
Where: n is 25% of real memory
Example: 128M for 512M of RAM
db_file_multiblock_read_count=n
Where: n is a number based on hardware. The ideal would be multiplier of 8k blocks to equal the disk stripe width.
shared_pool_size = n
Where: n is 10% or less of real memory.
Example: Approximately 10M for 512M of RAM
pga_aggregate_target=n
Where: n is 50% of real memory
Example: 256M for 512M of RAM
