Check for DBMS Server Process Errors on UNIX
The command to start the DBMS Server process (iidbms) from the installation owner login is ingstart -iidbms. If the DBMS Server did not start:
1. Verify that the recovery process (dmfrcp) is running. Details are described in Recovery Process Errors on UNIX.
2. Verify that the recovery process is not in a recovery state. (See Recovery Process Monitoring.) This is likely if there was a sudden shutdown because of a power failure or other system failure.
3. Try to start up a DBMS server. Issue the following command at the operating system prompt:
ingstart -iidbms
4. If you corrected a DBMS server problem, verify that Ingres starts normally. Shut down the partially started installation with the ingstop command.
5. Restart the installation with the ingstart command.
