2.1 Managing the dbmsrv Service

Oracle Exadata database servers run the Database Machine Service (dbmsrv), which provides management infrastructure similar to Management Server (MS) on Exadata storage servers. Together, dbmsrv and the DBMCLI command-line administration tool support monitoring, alerting, and other administrative tasks across bare-metal database servers, virtual machine hosts, and virtual machine guests.

• Using the DBMCLI Utility

To support dbmsrv, Oracle Exadata database server system images include the following users and groups.

The users and their UIDs are:

• dbmsvc: 12137
• dbmadmin: 12138
• dbmmonitor: 12139

The groups and their GIDs are:

• dbmsvc: 11137
• dbmadmin: 11138
• dbmmonitor: 11139
• dbmusers: 11140

You can modify these UID and GID assignments as described in the following topics:

• Changing User IDs and Group IDs for dbmsrv
  
• Manually Changing User IDs and Group IDs for dbmsrv
  Prior to Oracle Exadata System Software releases 18.1.12 and 19.1.2 when the migrate_ids.sh script was introduced, you can manually change the user and group IDs associated with the dbmsrv service users.
