#AQUA DATA STUDIO INCREASE MEMORY DRIVER#

Since the resultset does not retrieve all 5 000 000 rows into memory( only the amount specified by fetch size), it is unlikely this would be the cause of your memory error( but check with your JDBC driver known bug list anyways ).įirstly, ResultSet is an interface therefore it does not use up any memory, only instances of classes that implement it do so. Because this is a problem in the driver, there is no fix. The underlying reason for this problem is that the PostgreSQL JDBC driver requires excessive amounts of memory for streaming large bytea fields.

: Ran out of memory retrieving query results. Top returns something like this, which seems that the problem is not with the available memory on the machine itself. I started getting out-of-memory errors on os postgresql-9.1 server running on a 圆4 Debian with 4GB of RAM, dedicated to postgresql. Java runs with default memory settings, but those settings can be too small to run very large reports (and to run the JasperReports Server, for instance). So, you will need to increase the memory settings for your Java. Hi, it is the Java VM (virtual machine ie running Java execution) that is running out of memory. One of the large Decisioning queries uses a set of APIs which do not take this into account and which resulted in a memory error. On Postgres, the Fetch size for a query does not take effect unless the query is in an open transaction. PSQLException occurs when executing Decisioning queries that do not set any Fetch size for the retrieved results. : ran out of memory retrieving query results.
