Re: Server Sizing Guidance ... Urgent

[Joe D'Souza]

With that kind of configuration I would go with at least 3 servers in a
server group - considering you have at least 300+ concurrent users. Each
single instance with at least 4 GB RAM, an initial data file size of at
least 1 GB and a log size of about the same..

With that being said, your site is a better candidate for a UNIX operating
system instead of Windows. When it comes to large volume users and high
volume transactions, I'm not quite that confident about Windows.. There may
be a few who would disagree with me as yes there are sites out there
handling pretty high transaction volumes on Windows using MS-SQL.

If you are having virtualized environment, I'd like to warn you about
performance issues I have faced on VMWare where the instances didn't get the
necessary horse power needed to run the applications (almost a similar
environment like you mention).. And recently have considered standalone
servers instead of virtual servers running on VMWare..

Hope this helps...

Joe

PS: In actual practice the minimum recommended RAM for the AR Server and
apps seldom work and maybe ok for demo environments.. go almost double the
documented recommendations..

  Hi Lists,



  I need an urgent help regarding remedy server’s sizing.



  We need to implement IM, PM, CM and SLM modules and there are significant
customizations in IM and CM modules. Along with that the CMDB will be
significantly customized to cater to above four modules.



  Also the AIE integration with CMDB to populate it from 3 to 5 discovery
tools and ARDBC integration with AD are in scope.



  Also 300+ Concurrent users will be using the ITSM modules on first go

  The environment is Windows 2003 EE SP 2, SQL Server 2005 EE, ITSM 7.0.2
and CMDB 2.1.



  I am urgently looking for a document/theory/calculation matrix which can
guide me to give the hardware requirements (Most Significant is PRIMARY
MEMORY) for a QA and Production Server on Virtualized environment.



  There will be 6 boxes on a big virtualized box and there will be three

Production environment.



  The knowledge I have is:



  RAM :- 2 GB for AR Server + 1 GB for Mid-tier + 2 GB for each Major ITSM
module (from ARS Docs), but I need plenty of FACTS and INFORMATION to give a
concrete base for asking the Hardware which can cater my requirements and
satisfy a really tough customer.



  After all my searches now I rely on the vast experience of this list to

Server Sizing Guidance ... Urgent

Haven't tried it against Oracle XE on Vista yet, but I think I'm just 
as likely to try running Oracle XE on the Ubuntu VMWare session, and 
attempt to install 7.1 against that - before I start sweating blood 
over the weekend, is it likely to install?


Remedy _will_ work with Oracle XE on Linux.  You need to hack the 
install script, around line 4288 ,

if you don't have an officially supported distribution.
 OpenSUSE and SLED worked easily after that, I'm not sure if Ubuntu 
might need a little work.

Re: Iritive Search on Set Fields

[Carey Matthew Black]

SMR,

I would think that a table field would get the job done very easily.
The only "trick" would be that you need an active link guide to set
the value, refresh the table field, check the number of rows in the
table and decide to either stop, or shorten the string and loop
through the guide again. So something like this...

Table field qual: 'field_to_find_value_in' LIKE $String_to_look_for$+"%"

"OnReturn" active link --> Set a field ('String_to_look_for') with the
initial value then call a guide.

Guide:
 Lable: "Start"
  AL0 : Action 0: 'zLength' = LENGTH($String_to_look_for$)

  AL1 : RunIf : 'zLength' >=1
  AL1 : Action 0: Refresh table field
  AL1 : Action 1: Set field 'zInt' = $ LASTCOUNT$
  AL1 : ELSE Action 0: Exit Guide

  AL2 : RunIf: If : $ LASTCOUNT$ <= 0 AND 'zLength' >=2
  AL2 : Action 0: 'String_to_look_for' =
LEFT($String_to_look_for$,LENGTH($String_to_look_for$)-1)
  AL2 : Action 1:  GOTO LABEL "Start"

That guide should exit when it finds one or more records in the table
refresh or it should shorten the string (down to one character [ You
might want to change that AL1,AL2 RunIf's a bit] ) and try again.

Then if you could also choose to add another active link "OnReturn"
and do a set field action (if you want to show a picklist instead of
the table field) or you can call a guide...etc... You might even want
to have an active link to check for the case of 'String_to_look_for'
being = $ NULL$ and tell the user that "no match was found for any of
those combinations" too.

HTH.

Iritive Search on Set Fields

[Marquez Rankin]

I need to create a search which will search for a string (ie. "LMNOPQR"),
then search that minus a character (ie. LMNOPQ") if no records match and so
on.

I would like to have this OnReturn of the character field.

I have experimented with writing direct SQL and/or using a chain of active
links with 
*SUBSTR*
to
remove the last character

Has anyone done this in Remedy?  I'd like to limit this to Remedy code but
SQL is an option.

Re: User Sizing ?

[Rami S Ayoub]

Carey,

Thank you I found one white paper , but still I don't have clear
computability for what I'm trying to do ?

Subject: Re: User Sizing ?

Rami,

   Your answer completely depends on the application the users will be using
and the type of actions they will be taking in that application.
( Even a few users doing a bad search will bring any application/RDBMS to a
crawl.) Generally however there is a "white paper" that BMC published for
ITSM sizing. From memory I think 200 users is sized to be a "small" install.
(maybe it was medium, but I think it was still small. ) I also think there
are considerations for what clients the users will be using. ( User Tool,
Mid-Tier, Crystal Reports, Import tool, ect... )

   Generally however, buy the hardware that you can afford to by and then
try to do performance tuning at the DB when needed. (And user education
whenever possible.) You likely will also find that your hardware/performance
needs change over time. So be prepared to adjust and improve things as time
passes too.

HTH.

User Sizing ?

Hi List,
 
There is methodology for the sizing for example if I have 200 users they
will using the system , there is any requirement or compatibly matrix for
this ?
