What to do next

The removal process that is described in this topic can only remove packages from an accelerator. To free up space in the z/OS UNIX file system (zFS) of your data server, manually delete no longer needed IBM Db2 Analytics Accelerator for z/OS packages from the zFS. To do so, open a UNIX System Services shell and delete the files by using the rm command.
