Configuring an OpenVMS Cluster System 8.7 Running AUTOGEN with Feedback To implement this technique, you can create a command file like that in step 1 of the procedure in Section 8.7.4, and submit the file to the computer’s local batch queue from the cluster common SYSTARTUP procedure. Your command file conditionally runs the UETP LOAD phase and then reboots the computer with AUTOGEN feedback. 8.7.4 Creating a Command File to Run AUTOGEN As shown in the following sample file, UETP lets you specify a typical user load to be run on the computer when it first joins the cluster. The UETP run generates data that AUTOGEN uses to set appropriate system parameter values for the computer when rebooting it with feedback. Note, however, that the default setting for the UETP user load assumes that the computer is used as a timesharing system. This calculation can produce system parameter values that might be excessive for a single-user workstation, especially if the workstation has large memory resources. Therefore, you might want to modify the default user load setting, as shown in the sample file. Follow these steps: 1. Create a command file like the following: $! $! ***** SYS$COMMON:[SYSMGR]UETP_AUTOGEN.COM ***** $! $! For initial boot only, run UETP LOAD phase and $! reboot with AUTOGEN feedback. $! $ SET NOON $ SET PROCESS/PRIVILEGES=ALL $! $! Run UETP to simulate a user load for a satellite $! with 8 simultaneously active user processes. For a $! CI connected computer, allow UETP to calculate the load. $! $ LOADS = "8" $ IF F$GETDVI("PAA0:","EXISTS") THEN LOADS = "" $ @UETP LOAD 1 ’loads’ $! $! Create a marker file to prevent resubmission of $! UETP_AUTOGEN.COM at subsequent reboots. $! $ CREATE SYS$SPECIFIC:[SYSMGR]UETP_AUTOGEN.DONE $! $! Reboot with AUTOGEN to set SYSGEN values. $! $ @SYS$UPDATE:AUTOGEN SAVPARAMS REBOOT FEEDBACK $! $ EXIT 2. Edit the cluster common SYSTARTUP file and add the following commands at the end of the file. Assume that queues have been started and that a batch queue is running on the newly added computer. Submit UETP_ AUTOGEN.COM to the computer’s local batch queue. $! $ NODE = F$GETSYI("NODE") $ IF F$SEARCH ("SYS$SPECIFIC:[SYSMGR]UETP_AUTOGEN.DONE") .EQS. "" $ THEN $ SUBMIT /NOPRINT /NOTIFY /USERNAME=SYSTEST - _$ /QUEUE=’NODE’_BATCH SYS$MANAGER:UETP_AUTOGEN 8–42 Configuring an OpenVMS Cluster System
Configuring an OpenVMS Cluster System 8.7 Running AUTOGEN with Feedback $ WAIT_FOR_UETP: $ WRITE SYS$OUTPUT "Waiting for UETP and AUTOGEN... ’’F$TIME()’" $ WAIT 00:05:00.00 ! Wait 5 minutes $ GOTO WAIT_FOR_UETP $ ENDIF $! Note: UETP must be run under the user name SYSTEST. 3. Execute CLUSTER_CONFIG_LAN.COM or CLUSTER_CONFIG.COM to add the computer. When you boot the computer, it runs UETP_AUTOGEN.COM to simulate the user load you have specified, and it then reboots with AUTOGEN feedback to set appropriate system parameter values.
