How to solve the IDB-2003 error?
When multiple table Association queries are executed, the IDB-2003: Aggregation/Distinct memory limit is exceeded error is encountered
How to solve?
Answer Answered by David Thompson in this comment.
This means that the query execution is using more UM memory than you have. If you are running a single server deployment, you should look at increasing the TotalUmMemory setting and decreasing NumBlocksPct, this will trade off increased memory for query processing at the expense of disk block caching. The defaults are 25 and 50 and normally we recommend you keep the total of these as 75 especially on a lower memory machine. If you have a multi node deployment, increase TotalUmMemory. Alternatively you need more physical memory.
