Error in Process method of Component: QueryEngineServer, Project Nico's MD Population Opt for Cubes, Job 908, Error Code= -214721544.) System Error (EMFILE) - Too many open files. (QueryEngine encounter error: MFileSystem:OpenStream: ::fopen failed for '/iserver-install/BIN/Linux/MSIReg.reg_lock'. The following error is from publishing a cube in MicroStrategy Web. The following examples show the errors you may encounter if this limit is met through usage of this feature against a Linux Intelligence server. When using memory mapped files (MMFs) on systems with large numbers of loaded cubes, particularly partitioned cubes, it is possible to exceed the OS-configurable limit of open files per process. Memory mapped files are used, unless disabled at lower level or the disk requirement shown above is not met. Unless they are enabled at a lower level. Regardless of the settings at the lower level. Turn-off the capability without exceptions Memory mapped files are only created after fetching data and only for cubes smaller than approximately 1 GB. Uses the setting determined at higher levels, such as the project for a cube, an environment for a project, etc.Īpply best strategy to maximize performance with given resources The behavior for each of these settings is as follows: Value You can hover over the longer options, such Apply best strategy to maximize performance with given resources and Turn-off the capability without exceptions to view their full text. The usage of memory mapped files is configurable through MicroStrategy Workstation at the environment, project, and cube (excluding live connect) levels, with the options for the project level shown below. These files are deleted if the cube is completely unloaded, and created when the cube is published or loaded again. The location of this CubeGovern folder may vary, but can be found from the DSSErrors entry referenced in the Requirements section. This folder may contain a single file for non-partition OLAP cubes, or multiple files for partitioned cubes (based on number of partitions and attributes used) and MTDI cubes (based on number of fact tables, along with partitioning). When enabled, a file or set of files are created for each managed cube under a CubeGovern folder, with structure \CubeGovern\. The number of descriptors for Linux, using the nofiles limit, should be set to at least 65535 as mentioned in Recommended System Settings for Linux. ![]()
