======= 

This error/exception indicates that the number of connections specified in the TRA file is not adequate. Check the following settings in the TRA file and make sure the values are correct. If you have already set a value for the pool.max, make sure that the be.oracle.dburi.active.0 true is set.

be.oracle.dburi.pool.initial.0
be.oracle.dburi.pool.min.0
be.oracle.dburi.pool.max.0
be.oracle.dburi.active.0 true
be.oracle.dburi.pool.enforce.0=true

Note:
------
If using BE 3.0.1 HF2, check if the following property is also included in the CacheServer TRA file. You should have this property in your Inference Agents TRA file. If your agents does not use the dbconcepts feature, refer to the BE 3.0.1 HF2 readme.txt file.

be.dbconcepts.dburi
