DOCUMENTATION: What is the "nbpemreq" command used for in Veritas NetBackup (tm) 6.0?
Details:
Manual: NetBackup (tm) 6.0 Commands for UNIX, Page(s): 391
Modification Type: Supplement
Modification:
The Veritas NetBackup (tm) 6.0 Commands for UNIX manual mentions the nbpemreq command, but doesn't explain what the command can be used for.
There are three options available for the nbpemreq command:
usage: nbpemreq -updatepolicies
usage: nbpemreq -predict -date <mm/dd/yyyy HH:MM:SS>
usage: nbpemreq -predict -dateu <unixtime>
The "nbpemreq -updatepolicies" will cause the NetBackup Policy Execution Manager (nbpem) to reread the existing policy configuration. The nbpem daemon will check for changes based on the Global attribute Policy Update Interval. By default, this is set to ten minutes. The
-updatepolicies option can be issued after making a change to a policy to allow the changes to take effect immediately. TechNote 278492, found below in the Related Documents, contains additional information for the -updatepolicies option.
# cd /usr/openv/netbackup/bin/admincmd
# ./nbpemreq -updatepolicies
The command will simply return the prompt after being run.
The "nbpemreq -predict" option replaces the functionality that used to be available from the "bpschedreq -predict" command. The "-date <date>" or the "-dateu <unixtime>" option must also be specified. The -predict option will display backup policies that are due to run on a specific day and time. This command will not display when a specific policy will run, rather it will display policies that are eligible to run and that have open backup windows during the time specified. Factors such as drive availability, max jobs per client, exclude dates, etc., will impact when a job can actually run.
# cd /usr/openv/netbackup/bin/admincmd
# ./nbpemreq -predict -date 9/15/2005 16:00:00
Predicted worklist for Thu Sep 15 16:00:00 2005

This will display the Retention level (rl), Client Name (client), Policy name (policy), Schedule Name (schedule) and Policy type (type). The rl and type values will display the numeric equivalent of the retention level and policy type.
The following caveats exist for the nbpemreq -predict command:
Running the -predict option without specifying a time will use a default time of 23:59:59 hours.
Running the -predict option and specifying a time in the past will display the nbpemreq usage.
Running the -predict option will only show backups that are eligible to run. It is not an indication of what jobs will run at a specific time.
The -predict option only checks if there is an open window for the backup and does not reflect any exclude dates that might be set for the schedule.
The following undocumented options exist for the nbpemreq command:
# nbpemreq -terminate
This will stop the nbpem daemon and the associated nbpem_email and nbproxy processes.
# nbpemreq -suspend_scheduling
This will stop the nbpem daemon from scheduling backups. Manual backups can still be initiated.
# nbpemreq -resume_scheduling
This will allow the nbpem daemon to resume normal scheduling of backups.
# nbpemreq -tables screen
This will dump the worklist to the screen. This will include each policy and schedule and the specific time it is next due to run.
