we’ve experienced a similar problem when running large queries on
postgresql 7.3. Once we upgraded postgres version to 7.4, the time to run
the same large query went down from 50 seconds to 5 seconds!
As I was looking through RT-Users digest a couple of days ago, I noticed
that one of the developers replied to a slow query question by saying that
there was no optimizer in mysql (as far as I recall). If that’d be the
case, queries like this one would take forever …

RT Users-
We’re using RT 3.4.1 with MySQL 4.0.21 with perl 5.8.6 on Linux (kernel
2.2.20).
We recently upgraded from RT 3.0.0 to 3.4.1 in the hopes that it would speed
up our ever-slowing-down system. A number aspects of the system did indeed
seem to speed up, but replying to a ticket (hitting the “Reply” link from
Display.html) has become unbearably slow. Looking in my “mysql-slow.log”
log, I see that the main offending query is as
follows:
SELECT DISTINCT main.* FROM Users main , Principals Principals_1, ACL ACL_2,
Groups Groups_3, CachedGroupMembers CachedGroupMembers_4 WHERE
((ACL_2.RightName = ‘OwnTicket’)) AND ((CachedGroupMembers_4.MemberId =
Principals_1.id)) AND ((Groups_3.id = CachedGroupMembers_4.GroupId)) AND
((Principals_1.Disabled = ‘0’)or(Principals_1.Disabled = ‘0’)) AND
((Principals_1.id != ‘1’)) AND ((main.id = Principals_1.id)) AND ( (
ACL_2.PrincipalId = Groups_3.id AND ACL_2.PrincipalType = ‘Group’ AND
( Groups_3.Domain = ‘SystemInternal’ OR Groups_3.Domain =
‘UserDefined’ OR Groups_3.Domain = ‘ACLEquivalence’)) OR ( (
(Groups_3.Domain = ‘RT::Queue-Role’ AND Groups_3.Instance = 5) OR (
Groups_3.Domain = ‘RT::Ticket-Role’ AND Groups_3.Instance = 43004) )
AND Groups_3.Type = ACL_2.PrincipalType) ) AND (ACL_2.ObjectType =
‘RT::System’ OR (ACL_2.ObjectType = ‘RT::Queue’ AND ACL_2.ObjectId =
5) ) ORDER BY main.Name ASC;
If I manually run the query, it takes around 50 seconds to complete. If I
run an EXPLAIN on it, I see:
| table | type | possible_keys
| key
| key_len | ref | rows | Extra
|
| ACL_2 | range |
ACL1,RightName,PrincipalType,ObjectId,ObjectId_2,ObjectType,PrincipalId,
PrincipalType_2,RightName_2 | ACL1 | 54 | NULL
| 3 | Using where; Using index; Using temporary; Using
filesort |
| main | ALL | PRIMARY,Users3,Users_id_idx_mwp
| NULL
| NULL | NULL | 35305 |
|
| Principals_1 | eq_ref | PRIMARY,Disabled,id
| PRIMARY
| 4 | main.id | 1 | Using where;

| CachedGroupMembers_4 | ref | DisGrouMem,GrouMem,MemberId
|
MemberId | 5 | Principals_1.id | 1 | Using

| Groups_3 | eq_ref |
PRIMARY,Groups1,Groups2,Type,Domain,id,Instance,Type_2
| PRIMARY | 4 |
CachedGroupMembers_4.GroupId | 1 | Using where; Distinct
|
Does anyone know of any quick fix for this? Creating a new index or
something? I’ve seen a number of people report the problem on the list
in the past, but I couldn’t find any satisfactory solution.
A second question: is the file rt-3.4.1/etc/constraints.mysql meant to
be used? It looks like it might contain some useful foreign key and
index definitions, but it never appears to be automatically called, and
I can’t find any reference to the file in any documentation anywhere.
Is it experimental, or can it be applied to an existing RT schema?

Our organization also just threw out Track-It for the reasons Atom
listed below. We did not use the hardware/software audit feature. SMS
does the job for us. Track-It also does not an easy way to time-stamp
updates to the ticket. When the staff work on a ticket, email is sent
manually. All updates have to be cut-and-paste in which is a cumbersome
task so many of them skipped this step which brought up problems during
SOX auditing.
The best feature we got from RT was email notification and the ability
to work on the ticket via email. It’s much simpler for the users and
the staff. We use auto-assigning owner based on queue script to
simulate that feature in Track-It.
Here is an additional list of feature comparision:
Crap about Track-It:
- Does not time-stamp changes to the ticket. You can’t tell when was
the last time the end user update the ticket or the staff update the
ticket. Dates can be changed easily by the staff. (ie, closed today
but specify that it was closed 2weeks ago)
- It’s IE-centric !!!
- It runs on Windows so it’s another MS box to worry about for security
Plus for RT:
- Multiple users can be part of the ticket (cc or requestors). This is
really useful for us especially for approvals. Users make request for
some additional access, cc: their manager. The manager then can reply
with the approval. In Track-It, the staff would have to manually send
out the notification on manager, update that they did send it out. Once
the manager approved, the staff would need to copy and paste the reply
into the Track-It (SOX requirements).
- It integrates well with our Active Directory (we pull name, phone
number, office, and department from AD). 1 password for both system
(huge plus). People can no longer give excuses that they can’t put in a
ticket because they forgot their Track-It password. The Staff no longer
needs to create the account for helpdesk. They just simply log in the
first time to create the account.
Account information gets updated automatically whenever it changes under
AD. (We have a weekly script that sync the database)

Subject: RE: [rt-users] RT vs …
I have recently moved our HelpDesk away from Track-It into RT. Track-It
is first and foremost a computer tracking and auditing system. The
HelpDesk facilities are half-baked, at best; we used Track-It for three
years, and it never got any better. I hated Track-It.
- It does not integrate well into email.
- Tickets have to be requested and updated from the Track-It interface.
- The Track-It client is slow.
- Track-It has virtually no ticket-management/escalation ability.
- Nobody liked to use Track-It, none of our users entered tickets in
it and none of the HelpDesk used Track-It to manage tickets.
RT has been a huge success and people are actually using it.
- It is much easier to enter tickets into RT.
- RT can send out notifications via email.
- The RT inteface is much easier customize and use.
- Ticket tracking, ownership, and escalation are very easy to use.
But Track-It has some features that you may find useful.
- It has a client that can audit computer hardware and software.
- It can associate a ticket with a specific user/system.
- It can manage purchases and assign the equipment to a system.
We still have Track-It around to audit computers, but as soon as I can
replace that capability it’s going out the window. I don’t know what
kind of features you want from Track-It, but I would take a hard look at
other options before purchasing it.
Perfection is just a word I use occasionally with mustard.

Hi,
Let me first say I am being sincere here with my questions. I simply
wish to find reasons to keep RT over Track-IT. It’s solid and does a
good job.
Need your thoughts. I wish to keep RT, unfortunately it seems it’s not a
case of apple for apples, and my workmate puts together some good points
and Track-IT seems feature rich. Mind you that unlike what he says about
us putting RT in to get us started was crap. No one in their right mind
installs RT on Mandrake linux as a short term stop gap.
The way he puts things makes track-it definitely is much more feature
rich.
From what he says below, Track-it seems to be much more than just a
helpdesk.
Any points in favour of RT?
Anyone usedTrack-IT or know about it?
Anything better than these two products?
Anyone contract offer setup support for RT? As the prices my workmate
found on the Bestpracticle site are beyond our scope
Your thoughts? Please note that when I drafted my email to him, I did
not know what exactly the product was he was looking at.
Begin my original message
Over the weekend I enabled the following in RT:
1. Job - Escalation
o Jobs are escalated every 24 hours. They are set to highest
priority after 4 days (I est 4 days to be when we have
resolved most jobs by.)
2. End user - Self service web interface - users can check / add
jobs to the queue - requested by Pauld
3. Reminded - via email - sends a list of open/new jobs with
priorities to the help desk operator
o You are reminded via email about the following:
o New jobs from two days of creation
o Jobs still open every 7 days
Other requests Todo.
o Knowledge base - is installed not yet configured.
o Add sender's name to his/her job in the "new" jobs list in
the queue
o Enable Active directory authentication for Self Service web
interface.
Customisation
The system supports overlays, so one can customize any aspect of
the helpdesk with little interruption to future upgrades. Nice
feature. ie. Someone on the list is working on a wizard interface
(rather than
standard web interface) for users. Users can use a wizard to guide
them though the steps of adding jobs to the helpdesk.
Clarification on Friday's meeting
In relation to changing helpdesk systems, I'm not sure I explained
my view clearly in the meeting, as the thought of replacing the
helpdesk came as a surprise, especially after the pressure
involved in getting it up and running earlier this year. I'd love
to see what this other help desk systems offers, however at this
stage, I'm not convinced investing $5,000.00+ for a new helpdesk
will offer any significantly better benefits other than some basic
features (remote desktop, etc) already offered by Microsoft and
others for free.
One question raised in the meeting was that of having time to
enable helpdesk features in a timely manner. In addition to us
looking at this other helpdesk system, I'd like to get costs for
commercial support for the existing RT helpdesk system? As the
company that offers this product away also offers commercial
support. I think there are others too. I'd believe this could be
cost effective way of getting all the features we need.
Andrew,
Can you email me web site of the new helpdesk mentioned in the
meeting for assessment. TA
Workmates reply to my original email -------------------------------
I do not think that the RT Helpdesk has the ability to cover all aspects
of what we require. I think it is a great Free Package. But being free
does not mean that it is really free. The reason RT was deployed was
because we needed something to start tracking the work load and it has
done that job to an extent. It has also enabled us to develop a better
understanding of how helpdesk software works, and what we require as an
application with time for configuration and maintenance. Here is the
cost for installation support from the RT Helpdesk website_
http://www.bestpractical.com_ .
As the creator of RT and its related products, we are the most
knowledgeable company around when it comes to installing RT and RT-based
technologies.
o $2000 for up to six hours of installation and
installation-related troubleshooting.
o Installation support does not include configuration over and
above the defaults recommended by Best Practical.
o If we believe installation will take more than six hours, we
will attempt to notify you immediately so you can decide
whether we should continue for an additional charge.
We also offer customized support packages designed to meet specific
customers’ needs.
Academic discounts are available.
And here is the Application support (I am not sure what currency that
this is in I would guess it is in US dollars)
Bronze Level Support ($1,500 per quarter, $6,000 per year)
For companies processing less than 1,000 tickets per quarter in one
ticket database.
o Best Practical will respond to four separate incident
support requests per quarter.
o Best Practical will use reasonable efforts to respond to
incident support requests within one business day of receipt
of request.
o Support requests come via e-mail, sent by your company's
designated customer representative.
o _Installation support <installation.html>_ is not included.
o Additional support (e.g. for additional ticket databases)
available at $200 per hour for a minimum of four hours.
I suppose that you could look at it like the difference between Cisco
and Alloy networking products, RT Helpdesk is like an Alloy switch that
will do the job but not have all the bells and whistles of the Cisco
Helpdesk like the Pacen Track-It helpdesk system.
The commercial products offer significantly greater amount of benefits
not only remote desktop support as can be seen by there brief
descriptions below. From reading the full feature list of RT it does not
come close to being able to compete with either of these helpdesk
management products.
I received an email from ManageEngine_
http://manageengine.adventnet.com/products/service-desk/helpdesk-screens
.html
Some of the features of this HelpDesk are: Self-Service Portal,
Knowledge Base,
Service Level Agreement to keep track of warranty Ends,
HelpDesk Reports,
Integrated NMS (Auto ticket generation on failure of network devices or
applications monitored by OpManager. Centralized tracking of all network
failure related tickets which is very helpful during auditing. Timely
notice ability and rectification of network failures which results in
maximum uptime of all your network devices and applications. )
Hardware and Software Inventory,
Software Licence Tracking,
Purchase Order Tracking,
Contract Management,
Inventory Reports,.
Another one probably the best I have come across is this one from

ah yes, STDIN, that don’t work in the CLI there are fields where

Is there no “-” mechanism?
