Health check script suggestions...

Question

I used the health check script from metalink and it gave me few suggestion regarding my replication environment. One of them is ...
+ SUGGESTION: One or more propagation processes contain rule sets.
+ If a Propagation process will unconditionally forward all incoming
+ messages to its destination queue, and no rule-based transformations are
+ performed by the Propagation process, you should consider removing
+ the rule set for the Propagation process via dbms_propagation_adm.alter_propagation.
+ This will improve Propagation performance.
What is get from this is since i have same rule defined in propagation also as the one in capture, So suggestion from orcale is remove the propagation rule and let everything propagted through...anyhow since i want everything a capture process captures to be replicated on destenation.. so i removed the propagation rule. ..
But now the replication has stoped performing after that.....
can any one suggest me if my undersanding for above healthcheck suggestion is wrong then wht does it mean?

Answer 1

Did you remove both the rule AND the rule set, or did you remove only the rule?
If it was a positive rule set and you removed only the rule, you left an empty rule set as a positive rule set for the propagation. This will cause it to discard all messages.
An empty positive rule set is not the same as no (null) positive rule set. A null rule set means "forward all messages, since there is not filter rule", but an empty rule set means "there is a rule: that no message will be forwarded".
