Classification: Confidential It is (usually) not required for SMPE to be run under UID(0). However, as you have observed, it can cause problems with directory permissions.
-----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of David Spiegel Sent: Thursday, May 22, 2025 4:59 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: SysProg UID(0)? [CAUTION: This Email is from outside the Organization. Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] Hi, Is it absolutely necessary for SysProgs running SMP/e Jobs with USS Maintenance to have UID(0)? One reason I can think of is that the new files need to be owned by UID(0)/GID(0). Another is that since "System" Directories (e.g. /usr) are owned by UID(0)/GID(0), the new files cannot be placed there due to the existing permission bits.) Please confirm/deny my reasoning. Thank you in advance.
