Re: Load Balanced Remedy -> Load Balanced Oracle environments?

2008-11-19 Thread Barber, David
Sean,
 
More cause for concern then  we're currently running a hardware load 
balancer in front of 2 Remedy 7/Solaris boxes each running with (if I remember 
right) either 8 or 16 processors and 16 gig of RAM.  The backend database is 
running something like 16 processors and 32gig of RAM.  And we're currently on 
something like 70% DB utilisation.  I could be slightly out on the specs, but 
its about right.
 
Regards

Dave

Word of Caution on an Oracle RAC ... make sure you allocate a lot of memory to 
the db.   Here is what remedy recommends:

 

Small DB:

CPU   2

Memory  4 Gig

Concurrent Users1-400

 

sga_target  1-2 gigs

pga_aggregate-target1 gig

 

Medium DB:

CPU   4

Memory  8 Gig

Concurrent Users401-800

 

sga_target  3-4 gigs

pga_aggregate-target2 gig

 

Large DB:

CPU   8

Memory  16 Gig

Concurrent Users800 or more

 

sga_target  6-8  gigs

pga_aggregate-target2-4 gig

 

(page 18 on the Performance Tuning for Business Service Management Document)

 

 

One problem we ran into with RAC:  4 servers x 1 gig of memory is not equal to 
1 server X 4 gigs of memory.  The more memory you allocate to the DB the better 
your performance.  So if your remedy db is shared among other databases on the 
same server you may not be able to allocate a whole lot of memory to the db.

 

Something to keep in mind.

 

Thanks,

 

Sean

Been asked an intriguing question.

Our current Remedy environment :

- Hardware load balancer
- 2 x ARS 7.0.1 Remedy servers running on Solaris
- 1 x Oracle database server running on Solaris

Looking to the future and scaling the application, we're looking at load 
balanced Oracle solutions (I've heard about an Oracle RAC - real application 
cluster?), and our DBA has stated that Remedy will not work against an Oracle 
RAC in a load balanced mode.

Anyone on the list have experience of running Remedy against a load balanced

Many thanks - I'd say that at least 90% of the worklod is read/write - 
currently we've got up to 900 people actively updating tickets - this is 
scheduled to jump by another 400+ next week, with other leaps in the future as 
new functionality comes into place.

Hi Dave,
 
an Oracle RAC is fine, if your workload is mostly read access. But if you do 
many creates or modifys then you have locks on the database side. A Distributed 
Lock Manager must tell the other nodes about that lock. This can be a 
significant overhead compared to a single node database instance. We've 
experienced this problem and after switching to only one node the system 
performed better than before. But this was on Oracle 9i. I don't know if it's 
better in 10g

It would be a pain if it didn't scale, as we're looking at potentially massive

Did your DBA give you any reasons why it would not work? Theoretically it 
should.. All that Remedy requires is a connection string to the database 
(TWO_TASK if its a remote database - in a cluster this will most definitely be

Did your DBA give you any reasons why it would not work?
Theoretically it should.. All that Remedy requires is a connection
string to the database (TWO_TASK if its a remote database - in a cluster
this will most definitely be the case).

Subject: Load Balanced Remedy -> Load Balanced Oracle

** 

Been asked an intriguing question. 

Our current Remedy environment : 

- Hardware load balancer 
- 2 x ARS 7.0.1 Remedy servers running on Solaris 
- 1 x Oracle database server running on Solaris 

Looking to the future and scaling the application, we're looking
at load balanced Oracle solutions (I've heard about an Oracle RAC - real
application cluster?), and our DBA has stated that Remedy will not work
against an Oracle RAC in a load balanced mode.

Anyone on the list have experience of running Remedy against a
load balanced Oracle cluster?  Any case studies, or information to
share?

Re: Load Balanced Remedy -> Load Balanced Oracle environments?

2008-11-13 Thread Barber, David
The DBA reasoning : that the RAC is normally configured in a failover mode.  
Haven't spoken to him directly though.
 
It would be a pain if it didn't scale, as we're looking at potentially massive 
increases in workload - in the next few weeks database utilisation is expected 
to jump up to around 70%, and we're expecting much bigger leaps in application 
functionality and users.
 
Many thanks - as a few have said they're running against an Oracle RAC fine, 
then we'll have to look into configurations.

Regards
 
Dave
