- Events
- An event is simply a batch file that gets executed during a specific time of
- the day. In this event batch file you could do some of the following things:
-
- Pack your users and/or message bases
- If you are part of a mail network, you will most likely transfer mail packets
- Some third party products you use on your bulletin board may need to run
- utilities to update data bases, etc.
- Create a list of files on your system using PCBFiler and the /LIST parameter.
- Backup your system
-
- The previous examples are but only a few of the things you can do in your
- event. Since events simply execute batch files you are more or less limited
- by your imagination as far as what you want to run in your event.
-
- Adding An Event
- To define the events on your system, you need to go to PCBSetup | Event Setup.
- Next, you need to make sure that you have answered Y to the Is a Timed Event
- Active question.
-
- Finally, if you cursor down to the EVENT.DAT line and press 2 you will a
- screen that resembles the following:
-
- ══════════════════════════════════════════════════════════════════════════════

-
- The number to the left of each line is the event number that is being
- defined. The rest of the fields on the screen are as follows:
-
- Act You may enter either a Y or an N in this field. A Y signifies
- that the event is active and should be executed as configured.
- If you enter an N then the event will be considered inactive
- and will not be run as defined.
- Mod The mode of the event. You may enter either an E or an S in
- this field. If you enter an E then the event is a "rigid" or
- non-sliding event. If you enter an S as the event type then
- the event is referred to as a sliding event.If an event is an
- expidited or non-sliding event then PCBoard will make it's
- best attempt to execute the event at the time you specify as
- the beginning time even if it means cutting users time short.
- Batch File In this field, you need to specify the batch file you wish to
- execute for the event you are defining. Note that you are
- only given 8 characters for the batch filename. The reason
- for this is that by default this batch file will be run on
- all nodes. However, you can make node specific batch files by
- making the node number the filename extension. For example,
- if you entered a batch file of DAILY and you wanted node 5 to
- execute a different batch file then you would create a
- DAILY.005 file
- Begin Time This is the earliest time that you event will be run. The
- time that you enter in this field must be in 24 hour format
- and there must be a colon between the hour and minutes.
- End Time The end time is the latest possible time that you wish for
- the event to run. If the event has not run by the time that
- you enter, then the event will be skipped.
- Date This field enables you to specify the dates that PCBoard will
- run the event. For example, if you want the event to run on
- the first day of every month, then you would enter a date of
- 00-01-00. Entering a 00 signifies a wildcard. Using the
- previous example, this means that it would run for any month,
- and any year, but only when the day of the month is equal to
- 01. Another example would be to set the date to 12-25-00.
- This means that the event would run every Christmas day no
- matter what
- Last Date Contains the date that the event was last run on the node
- number that is specified in PCBSetup | Node Configuration.
- Not all events run system- wide therefore this field only
- contains the last date ran for the node you are currently
- editing.
- Days You may also control which days that the event you are
- defining is run on. In this field all seven days of the week
- are listed begining with Sunday and ending with Saturday.
- Simply enter either a Y or N which signifies whether you want
- to run the event on the day listed or not.
-
- As an example, let's say that you want to have an event that runs at 3:00am
- every morning and packs your message bases. The first step would be to edit
- your EVENT.DAT file in PCBSetup | Event Setup.
-
- First of all, you will put a Y in the Act column, because this is an active
- event and you do want it to run. Next, you would put an S in the Mod column
- because you would like for this event to run at 3:00am but you would not mind
- waiting for a caller to logoff before running the event.
-
- Next, you need to enter a batch filename. For lack of a better name you can
- enter PACKMSGS as the batch filename. Now you must enter the earliest time
- that you wish for the event to run. As outlined earlier, you want this event
- to begin at 3:00am so you would enter 03:00 in this column. If the latest
- that you want the event to run is 08:00am, then you would need to enter 08:00
- in the End Time column.
-
- Finally, you need to specify the date and days that the event will run. If
- you leave the Date column blank or filled with 00-00-00 it will run for every
- day of the week that you specify in the Days columns. Because the event will
- pack the message bases, you probably want it to run every day of the week so
- you would put a Y in every day of the Days column. Once you have done this
- you would have an entry which looks like the following:
-
- Batch Begin End Last Days
- Act Mod File Time Time Date Date SMTWTFS
- --- --- -------- ----- ----- -------- -------- -------
- 1) Y S PACKMSGS 03:00 08:00 00-00-00 YYYYYYY
-
- You have one last problem to overcome. You need to create the actual batch
- file that will execute your event. In actuallity, this is very easy to do.
- Simply highlight the batch file field you want to edit and press 2. Your
- default text editor that you defined in System Manager | Define Text &
- Graphics Editors will be used to edit the batch file.
-
- For example, your batch file might look like this:
-
- PCBPACK /AREA:ALL /MAXMSGS:1024 /MINMSGS:100 /DAYS:30
-
- This batch file simply runs PCBPack on all message bases. Once the message
- bases have been packed, BOARD.BAT is reloaded which will make the system once
- again available for callers.
-
- We have one final problem. By default this event would run on every node of
- the system. Obviously this would not be a good idea to have every node
- packing the message base at the same time. What you would do then, is to
- rename your batch file from PACKMSGS to something like PACKMSGS.003. By
- adding the .003 to the end of the filename, that tells PCBoard that it is a
- node specific file and that only node 3 should run that batch file.
-
- Multiple Nodes
- Frequently, you will need more than one node to participate in an event
- whether you want each node to perform a particular task or if you need all
- nodes to be down, it is important to understand how to control your events.
-
- Node Specific Events
- Most likely you do not want all of your nodes to run the event batch file.
- You may have one node that does all of the work while the other wait or do
- some other tasks. In the EVENT.DAT file you specify the base event batch
- filename. This is the batch file that will be executed for all nodes unless
- there is a node specific event batch file.
-
- To create a node specific event batch file, you simply create a file with the
- batch filename and an extension of the node number. For example, if your
- event batch file is called MAINT1 and if you wanted to make a batch file that
- only node 6 would execute, then you would create a batch file called
- MAINT1.006.
-
- When event time rolls around, all of the nodes except node 6 will run the
- event using the MAINT1 file. Of course, node 6 will use the MAINT1.006 file.
-
- If you wanted only node 6 to run the event and the other nodes to not even
- both going down for the event, then you would create the MAINT1.006 file and
- then delete the MAIN1 file. Since the other nodes would not have a batch file
- to execute, they will not execute the event.
-
- Making Sure All Nodes Are Down
- To perform global changes to the system such as sorting the user file, or
- doing a total backup of your system, you will need all of your nodes to be
- down. Perhaps the easiest way to accomplish this is to have your nodes
- simply run a program as they begin the event that will count for a certain
- amount of minutes or seconds while the event is running. When the nodes are
- down counting, they can then reload the board.
-
- As an example, let's assume that you are operating a three node system. You
- want node 1 to sort the users file. In order to do this, nodes 2, and 3 must
- not be operating. Quite simply, you create a node specific event file for
- node 1. If you event batch file is called USRSORT then you would create an
- event file called USRSORT.001. This batch file might look like the following:
-
- @ECHO OFF
- PCBSM /SORT;SECURITY;PRIREVERSEBOARD
-
- In your testing, you have found out that it takes about 4 minutes to complete
- the sorting process. Therefore, you need to make sure that the other nodes
- stay down for a bare minimum of 4 minutes. Just to be safe, you could even
- keep them down for 10 minutes or so because the time it takes to sort the file
- will increase as the number of users on your system increases.
-
- You should be able to find several utilities will will count for seconds or
- minutes on the PCBoard Support BBS. For example, if you found one that was
- called count and would count for the number of seconds specified, you would
- want to make your USRSORT batch file look like the following:
-
- @ECHO OFF
- COUNT 480BOARD
-
- Quite simply, this would make nodes 2 and 3 (because a USRSORT.002 or
- USRSORT.003 file was not found) count for 480 seconds, then reload the
- bulletin board. This should give more than ample time for the sort process
- to be completed.
-
- There are several other methods you can use to make sure all events are down
- and stay down. Most of these have been addressed by third party authors and
- are available on the PCBoard Support BBS by (Z)ippy scanning for EVENT.
