When a data service sorts data, it writes sort files, which can be quite large, to a temp directory. If the temp directory doesn’t have enough disk space, the data service fails. You can set the location of the temp directory.
The temp directory a data service uses for its temporary sort files is specified by the java.io.tmpdir system property on the grid server where the data service is running. The default location is <SDF-install-dir>/jboss/server/grid-server/tmp.
If you create a data service that sorts large result sets, be sure that the temp directory has enough disk space to write large sort files. Insufficient disk space will cause data service execution to fail because the sort operation is unable to finish.
If the grid server’s default temp directory can’t accommodate large files, you can change the system property to point to a different directory.
