![]() ![]() If you will be using less than a 1GB, then you should use the 32-bit version of ADS. ![]() The 64-bit version of ADS is not limited to 1GB (maximum value for “vmarg.2” can be more than 1024), but the 64-bit version uses twice as much memory for the same operations as the 32-bit version. The 32-bit version of ADS can use up to 1 GB memory (maximum value for “vmarg.2=-Xmx1024M” ) Text Results use three times more memory than Grid Results alone.ĭisable Charts in File -> Options -> General -> Chart -> ģ2-bit vs. If you will be working with large query results:ĭisable Text Results and Pivot Grid Results, and use only Grid Results. Please refer to the following section of the ADS online documentation: If it shows that the "Used Memory" size is nearing "Total Memory" size, you need to increase the amount of memory available to ADS (the "Max Memory" size). Manage Databases Access Data Sources Connect natively to over 40 relational and NoSQL DBMS platforms (Oracle, SQL Server, Db2, Sybase, Hive, MongoDB, MySQL, Snowflake. In the bottom right corner of Aqua Data Studio, you can see the "Used Memory" and "Total Memory" indicator. Control Versions Manage SQL scripts, database files, and Aqua Data Studio files with the full and integrated version control client for Subversion, CVS, Git, and Perforce. There have been numerous requests to Sun to change this behavior. The problem results from the fact that the “Total Memory” of the JVM is not released until you restart the JVM. The WebFOCUS, TIBCO WebFOCUS App Studio, or TIBCO FOCUS product. The amount of memory used by the application within the JVM is called "Used Memory". "Used Memory" will grow and shrink as the application uses memory, but "Total Memory" will increase only up to the size of the "Max Memory". Including Data From More Than One File: JOIN. As the application uses memory, the JVM will allocate additional memory from the OS as needed this amount is called "Total Memory". By default, Aqua Data Studio is limited to 256MB of memory (“vmarg.2=-Xmx256M”). This memory allocation is defined by the “vmarg.2” variable in the /datastudio.ini file). When the JVM starts, it has a defined "Max Memory". Such behavior is caused by Aqua Data Studio and JVM running out of memory. The issue also appears when ADS exports large amounts of data to external applications. If Aqua Data Studio crashes, becomes unresponsive, or displays no output when querying for a large amount of data, it has likely run out of memory.
