Compilation of the database

The compilation command creates a subdirectory of the TEC_RULES subdirectory of the interpreter type (the $INTERP Tivoli environment variable) being compiled for (that is, the operating system on which the compile procedure is performed), and puts the executable code in the new subdirectory, with the extension .wic.

The results of the compilation are displayed.

When a BAROC file causes compilation errors, you must delete the file before you re-import the corrected version of the file. Otherwise, a message notifies you that names have already been defined.

To delete a BAROC file (here, perf.baroc in the perf rule base, use this command):

wrb -delrbclass perf.baroc perf

After a rule base is compiled, it can be loaded to become available for use.

Loading a rule base recursively copies the entire ( TEC_CLASSES, TEC_RULES, and TEC_TEMPLATE ) directory structure into $DBDIR/tec/rb_dir.

  • On UNIX systems, do not attempt to put the directory structure in /.
  • Do not leave extraneous files, such as core files, in this directory structure.

In confirming the loading of a rule base, there are two choices--Load and activate the rule base and Load, but activate only when server restarts. If classes have been modified, then the second option must be selected. If only rules have been modified, the first option is a time saver because it skips bringing the server down and up again.

To complete the loading of the rule base, shut down and restart the event server since new classes have been added. (This temporarily disables Tivoli Enterprise Console. Perform this operation only in a test environment or in a controlled way on a production system.)

When Tivoli Enterprise Console starts, it goes to $DBDIR/tec/rb_dir. The rule base load action copied the files to $DBDIR/tec/rb_dir.

At this point, Tivoli Enterprise Console knows about the newly defined classes. Ultimately an event adapter will initiate the events, but for now, use the CLI command wpostemsg to send a test event instance. In this case, the SwapOut event is generated as though it were generated by the LOGFILE event adapter.

wpostemsg SwapOut LOGFILE

Use the wtdumprl (display the reception log) command to verify that the event was successfully received. In this case the word PROCESSED appears.

If the event was not successfully introduced, the message PARSING FAILED appears.

wpostemsg BOGUS LOGFILE

Because BOGUS is not a defined event class, the event instance will not be accepted, and wtdumprl displays the following result:

Misspelling an attribute name (for example, the pid attribute) causes the event instance to be rejected.

wpostemsg ppid=9090 SwapOut LOGFILE

Old News

IBM - compile a rulebase to not use .rbtargets.

 Technote (FAQ)   Problem During the rule base compile, the .rbtargets directory is created and customer does not want to use .rbtargets.  

Cause The rbtargets file have been set.  

Solution The setting for the .rbtargets is set by the file rule_sets_EventServer in the TEC_RULES of the rule base.

To disabled it such that the .rbtargets/EventServer/.. directories are not created, delete the rule_sets_EventServer file and the .rbtargets directory and subdirectories.


Recompile/load the rule base and stop/start the TEC Server for the changes to take effect.

NOTE: Do NOT rename the rule_sets_EventServer to eg. rule_sets_EventServer.bak as it will still be created with the directory structure of .rbtargets/EventServer.bak.
