A new TEC rulebase can be located in any directory. It's stupid to put it deep in the maze of Tivoli hierarchy. To create a rule base one need to use the command:
wrb -cprb -path /rb/dev/myrb myrb
You will get the following directory structure created:
drwxr-xr-x 2 root root 1024 May 17 2005 TEC_CLASSES/
drwxr-xr-x 3 root root 1536 May 17 2005 TEC_RULES/
drwxr-xr-x 3 root root 512 May 5 2005 TEC_TEMPLATES/
In TEC_RULES directory you will have the following files:
-rw-r--r-- 1 root root 25 May 3 11:38 .rule_builder.pro -rw-r--r-- 1 root other 0 May 3 11:38 rule_packs -rw-r--r-- 1 root root 0 May 3 11:38 rule_sets -rw-r--r-- 1 root other 0 May 3 11:38 rule_sets_EventServer -rwxr-xr-x 1 root root 725 Aug 11 2003 tec_forward.conf*
Now you need to remove legacy components:
cd /rb/myrb
rm -fr .rbtargets
cd TEC_RULES
rm rule_sets_EventServer*
The created rulebase is empty: it does not contain any rulesets of BAROC files. Now you need to import default rulesets and BAROC files.
The following rulesets are supplied by IBM and constitute a minimum that needs to be imported into any new rule base. They are stored in the default_rb directory ( $BINDIR/TME/TEC/default_rb or /opt/tivoli/TMF/bin/solaris2/TME/TEC/default_rb on Solaris). The directory contains quite a lot of files:
cleanup.rls event_filtering.rls notify.rls cleanup.rls.pro event_thresholds.rls ov_default.rls correlation.rls forwarding.rls rule_sets db_cleanup.rls heartbeat.rls rule_sets_EventServer dependency.rls heartbeat.rls.pro solaris2 dependency.rls.pro im.rls tec_forward.conf ebusiness.rls maintenance_mode.rls tecad_nv390fwd.rls ebusiness.rls.pro maintenance_mode.rls.pro tecad_nv390msg.rls escalate.rls netview.rls tecad_snaevent.rls event_activity.rls netview.rls.pro troubleticket.rls
The minimum set should include only five rulesets:
To import the rulesets into the rule base you need to use the command wrb -imprbrule, for example:
wrb -imprbrule $BINDIR/TME/TEC/default_rb/TEC_RULES/tec_server.rls myrb
Note: You can import the whole generic (the Default ) rulebase but this imports a lot of junk, don't do it.
wrb -cprb -rulesets -overwrite Default myrb
Default rulebase contains a bunch of BAROC classes:
DB2Agents.baroc itmwas_dm_events.baroc DB2CpuUtilization.baroc netview.baroc DB2DatabaseStatus.baroc root.baroc DB2HostThroughput.baroc sem_events.baroc DB2InstanceStatus.baroc tec.baroc DB2_Event.baroc tecad_hpov.baroc Tmw2k.baroc tecad_logfile.baroc WebSphere_MQ_Channel.baroc tecad_nt.baroc WebSphere_MQ_Queue.baroc tecad_nv390msg.baroc WebSphere_MQ_QueueManager.baroc tecad_nv6k.baroc as400msg.baroc tecad_ov.baroc dependency.baroc tecad_snaevent.baroc director.baroc tecad_snmp.baroc ebusiness.baroc tecadnw4.baroc hb_events.baroc tecados2.baroc ibm_director.baroc troubleticket.baroc
The minimum set of classes that you need to load is:
The root.baroc and tec.baroc files are imported automatically when you create a rule base.
You need to use wrb -imprbclass to do that:
wrb -imprbclass $BINDIR/TME/TEC/default_rb/TEC_CLASSES/dependency.baroc myrb
Note: You can import the whole generic (the Default ) rulebase this imports a lot of jredundant rulesets (junk), so this is not a recommeded way to do this unless you have no other.
wrb -cprb -rulesets -overwrite Default myrb
The easiest way to populate newly created rulebase is to copy old rulebase into new
wrb -cprb -overwrite ntiv ntiru
You can also copy separately rulesets and BAROC classes using options -classes of wrb -cprb command.
After creation of a rulebase you need to remove legacy components that are remnants of AIM -- Availability Intermediate Manager -- discontinued product that was replaced with gateway based Zurich Correlation engine (Java application that is driven by XML tables).
cd /rb/myrules
rm -fr .rbtargets
cd TEC_RULES
rm rule_sets_EventServer*
After you remove those the system will not recreate them. See http://www.tivoli-ug.org/newsletter/Tivoli_Advisor-Issue3.pdf
wrb -crtrb -path /rb/myrule myrules
To check:
wrb -lsrb -path
wrb -lscurrb -- displays the current database
Do not modify the default rule base. It should serve as a known good rule base.
The command wrb -lscurrb reports the name of the current working rule base name. Tivoli provides a default rule base called Default.
An existing rule base, such as Default, can be copied into the new rule base as a starting point. Only one rule base is active at any given time. The import procedure copies the BAROC file into the TEC_CLASSES subdirectory and modifies the .load_classes file. The order in which the classes are loaded must be controlled because superclasses must be defined before subclasses because of multiple inheritance.
Whenever changes are made to a rule base, the rule base must be recompiled to make the modifications available when the rule base is loaded.
