And, usually, it is only the SASUSER library that becomes read-only on the second and subsequent instances. So if you are trying to write to SASUSER in the second instance, you might have an issue. You only can have 1 write-access copy of SASUSER open at a time. All subsequent instances of SAS open a read-only copy of SASUSER. This mostly impacts SASUSER.PROFILE and SASUSER.REGSTRY. The files are usually copied to WORK for the session, and if something can't be copied, you see messages about that, too. Typical messages you get in the log are: NOTE: Unable to open SASUSER.REGSTRY. WORK.REGSTRY will be opened instead. NOTE: All registry changes will be lost at the end of the session. WARNING: Unable to copy SASUSER registry to WORK registry. Because of this, WARNING: you will not see registry customizations during this session. NOTE: Unable to open SASUSER.PROFILE. WORK.PROFILE will be opened instead. NOTE: All profile changes will be lost at the end of the session. NOTE: This SAS session is using a registry in WORK. All changes will NOTE: be lost at the end of this session. NOTE: Unable to open SASUSER.PROFILE. WORK.PROFILE will be opened instead.
