  11 Scheduling Recovery Manager Batch Jobs on Windows NT


  11.1 Running Recovery Manager in Batch Mode

      Recovery Manager has a non-gui interface for executing command
      files from a DOS window. Once a command file is created in the
      GUI, it can be executed either within Recovery Manager using the
      Command File button in the Main window, or it can be executed in
      a DOS window with the following syntax:

      Recovery Manager Batch mode syntax (spacing is important):
      (installed_path)\recov.exe -j command_file

      The logfile that you specified in each backup and restore job when
      you created the command file will be appended with the new sta-
      tus information. The Recovery Manager logfile, recov.log, will
      record a history of the user action.

  11.2 Using Windows NT to Schedule Batch Jobs

      Setup of Schedule service

      Go to Main->Control Panel->Services, select the Schedule service,
      and change the Startup Type to be automatic (if not already) us-
      ing the Startup button. [The same information can be found through
      Recovery Manager's main window Help icon, following the link "Prod-
      uct Overview->Product Features-> click Here for Batch mode .."
      to "Executing a Command File in Windows NT in Batch Mode".]

      Usage of the "AT" command

      Once the Scheduler service is started, the AT command runs a batch
      file at a specified time. The default is to run jobs on the lo-
      cal computer; the \\computername switch allows you to schedule
      a job to run on a remote computer.

      Type AT ? in the dos window for more info. Each scheduled job has
      its own id spawned. You can list all scheduled jobs by typing "AT"
      with no arguments, and you can delete a job from the list by spec-
      ifying its id with the /DELETE switch.

      Other switches such as /EVERY:date[,...] and /NEXT:date[,...] al-
      low you to define a repeat sequence to the job. Specify the full
      name of the day(s) of the week and/or the number of the day in
      a month in a comma-separated list after the colon.

                                Important

           Jobs using the /EVERY switch live forever unless deleted
           by their process id. All other jobs are removed by the
           system once they have been executed, unless the user
           deletes them. Rebooting or restarting the computer has
           no effect on the jobs in the scheduler.

      Job Create Syntax:
      WIN AT [\\computername] time [/every:date[,...]] [/next:date[,...]]
      command

      Job Destroy Syntax:
      WIN AT [\\computername] id /delete OR /delete /yes

      AT command Scheduling Examples

      o Example 1: Run batch.bat at 2:30 pm today
        AT 14:30 c:\recov\batch.bat

      o Example 2: Delete first job
        AT 1 /delete

      o Example 3: Run "batch.bat" at 9:00am every Thursday and Fri-
        day
        AT 9:00 /EVERY:th,f c:\recov\batch.bat

      o Example 4: Run "batch.bat" at 9:00am next Wednesday only
        AT 9:00 /NEXT:w c:\recov\batch.bat

      o Example 5: Run "batch.bat" at 3:45 pm on the 1st and 15 day of
        each month, and on every Friday
        AT 3:45 /every:1,15,f c:\recov\batch.bat



  12 Automatic Network Configuration with Recovery Manager -
     Examples

      Once a Backup operation of a network has been saved, Recovery Man-
      ager can be used to restore that configuration. Running Recov-
      ery Manager in batch mode with the "AT" command allows the user
      to restore configurations automatically on a time schedule of the
      user's choosing.

      A few examples are given below, and how each would be implemented
      follows the problem description. Each assumes that Recovery Man-
      ager was installed in directory path c:\recov for simplicity, and
      that Windows NT's Schedule service has been started and is con-
      figured properly.

  12.1 Example 1 - Saving a Baseline Configuration

      o Task Description
        A network manager wishes to automatically save the current con-
        figuration of her hub once a week.

      o Solution

        o  Steps Within Recovery Manager

           Using Recovery Manager, the network manager opens a Backup
           window via the GUI for the hub, specifies "Select All" to
           select all supported devices and parameter subsets, and checks
           the "Save to Command File" box so that the entire operation
           is saved to a command file. She chooses the logfile name "base-
           line.log", the saveddata file name "baseline.sdf", and the
           command file name "baseline.cmd".

        o  Steps Outside Recovery Manager
           She creates a batch file, "baseline.bat", with the follow-
           ing contents:
           C:\recov\recov.exe -j C:\recov\baseline.cmd

           She then issues the following command in a DOS window at the
           prompt to schedule "baseline.bat" to run at the proper time:
           C:\> win at 20:00 /EVERY:f C:\recov\baseline.bat

           This will run "baseline.bat" every Friday at 8:00pm, which
           will save the current configuration of the hub to "baseline.sdf",
           append the status information for the operation to "base-
           line.log", and append event history information to "recov.log".

           To keep separate copies of the saved configuration from week
           to week, she manually copies "baseline.sdf" to a filename
           of the form "<today's_date>.sdf" when she arrives at work
           on Monday morning of the next week. To see if the saved con-
           figuration data has changed from week to week, she can in-
           voke an external facility such as "WinDiff" on .sdf files
           from successive weeks.


  12.2 Example 2 - Restoring Daily and Nightly Configurations

      o Task Description
        A network manager wishes to configure his network at differ-
        ent times based on user demand. He knows that the network has
        two distinct utilization trends (daily and nightly operation),
        and wishes to automatically configure each hub in the network
        for these two different modes of operation. The daily config-
        uration will define parameters that will maximize bandwidth dur-
        ing the weekday or peak hours, and the nightly configuration
        will define lower-cost parameters for the off-peak nightly hours.
        For simplicity, it is assumed that his network is composed of
        two DEChub900 hubs.

      o Solution

        o  Steps within MultiChassis Manager/Recovery Manager
           The network manager has to configure each hub for daily op-
           eration using MultiChassis Manager. Once a configuration is
           applied for each hub/agent, he can invoke Recovery Manager
           from within MultiChassis Manager using the Applications pull-
           down, and Backup the daily configuration information for each
           hub to a separate saveddata file. This has to be repeated
           for the nightly configuration, where separate and unique saved-
           data files for each hub are chosen.

           A Restore window is then opened for each hub, specifying the
           saveddata file of each hub's daily configuration from the
           previous backup operation. A common command file name is se-
           lected to contain the commands that restore daily config-
           urations for both hubs. This is repeated for the nightly op-
           eration, where separate Restore windows for each hub are opened
           that reference their respective nightly saveddata parame-
           ter files. A common command file name (different from thecom-
           mand file used for the daily configuration) is selected to
           contain the commands that restore nightly configurations for
           both hubs.

           The desired result of these steps is the creation of com-
           mand files that will restore the daily and nightly param-
           eters for each hub. This eliminates the need to go back through
           the "Restore" window to restore a particular configuration;
           one need only run the command file through Recovery Manager's
           GUI Command File icon, or run it in batch mode from a DOS
           window.

        o  Steps Outside Recovery Manager
           For this example, assume that the network manager saved the
           command files for restoring the daily and nightly config-
           urations within Recovery Manager as c:\recov\daily_r.cmd and
           c:\recov\night_r.cmd, respectively. These will be referenced
           in batch files that are run with the "AT" command for job
           scheduling, as will follow.

           For restoring the daily configuration, he would create a batch
           file, "daily.bat", with the following contents:


           c:\recov\recov.exe -j c:\recov\daily_r.cmd

           To schedule the daily configuration to be applied every day,
           he would type at the DOS prompt:


           c:\> win at 6:00 /every:m,t,w,th,f,s,su c:\recov\daily.bat

           This would restore the daily configuration at 6:00am every
           morning.


           For restoring the nightly configuration, he would create a
           batch file, "nightly.bat", with the following contents:

           c:\recov\recov.exe -j c:\recov\night_r.cmd


           To schedule the night configuration to be applied every night,
           he would type at the DOS prompt:

           c:\>win 20:00 /every:m,t,w,th,f,s,su c:\recov\nightly.bat


           This would restore the night configuration at 8:00pm every
           night.
