SYSNAM is a privilege that lets the user's process bypass discretionary access controls and insert names into the system logical name table and delete names from that table by using the Create Logical Name ($CRELNM) and Delete Logical Name ($DELLNM) system services. A process with this privilege can use the DCL commands ASSIGN and DEFINE to add names to the system logical name table in user or executive mode and can use the DEASSIGN command in either mode to delete names from the table.
To mount a system volume or to dismount a system or group volume with the appropriate mount or dismount command or system service, a user must have the SYSNAM privilege.
The SYSNAM privilege also lets a process perform the following tasks:
- Access a MAIL maintenance record
- Modify a MAIL forward record
- Declare a network object
- Create an IPC association
- With CMKRNL, add or remove an identifier to system rights list
