RE: Restricting a process -- DOMINO400

Lots of great information, and you've nailed the cause  --  we have an 
unfortunately high percentage of users with FTI set to immediate to 
support a third-party product.  The product apparently only sees new 
messages after they've been indexed and hourly was not fast enough to suit 
them.  Changing it back to hourly is gradually becoming more likely now 
that the initial excitement of the new product is trailing off, but I 
don't have a date I can put on my calendar yet.  Am I correct in thinking 
that UPDATE_SUPPRESSION_TIME will basically prevent the system from 
indexing the same mail file within the stated time?

Looking into UPDATE_SUPPRESSION_TIME, I see that there is also an 
UPDATE_SUPPRESSION_LIMIT that takes a 0 or 1 toggle, but I don't see a lot 
of explanation for exactly what it does.  Do you know?  They also warn 
that this will increase the load on the CPU, which seems to be 
counter-intuitive, considering what I've been seeing -- I don't have more 
CPU to use!  But I'm assuming that's compared to the normal CPU load of 
someone that's not running their indexing like we are...

My Update task currently seems to operate on one database at a time.  If a 
single database takes over 60% of my CPU, I'm not sure it would be a good 
idea to add another Update task -- wouldn't that just open the door for 
another massive drain on resources?

Thanks for the response!
Patrick

RE: Restricting a process






Patrick, 

Make sure the full text indexes are set to hourly instead of immediate. 
Very few users
ever need an immediate full text index update on their email database.

That will keep very active databases from consuming all of your CPU. Watch 

the console during
heavy usage to determine which databases are using up all of the CPU. Some 

may have allot of folders
and a Full Text index with attachment indexing. Attachment indexing is 
bad, disable it where possible. 

UPDATE_SUPRESSION_TIME= is the ini variable to Queue the index jobs to 
make it 
more efficient. Indexer is the most CPU intensive job, and is rarely idle. 



Try UPDATE_SUPRESSION_TIME=10

You can also use multiple Update tasks, via the ini variable UPDATERS=X

We run 3 on servers with allot of email databases.

If you want to restrict update or updall at the OS level then you can 
easily create a user class (CRTCLS)
to do so on iSeries for Job Run Priority. We do it here and have set 
Update to a priority of 30, to insure it does
not pin the CPUs. 

You will find a number of posts on CRTCLS it if you search the forum.

Regards, 

Sean
