Amsterdam anyone?

There is a contract in Amsterdam that is looking for an experienced analytics consultant. Please get in touch with me if you are interested. I can put you in direct contact with the manager there.

Role of Honour

I received lots of good feedback on my recent rantings about the market, so have decided to set-up a role of honour for OBI specialists. We know who the major players are, so I'll set-up a webpage listing consultants, companies, projects, agents and general information.

If you would like to be included just let me know, and send me a profile. If there is anything you specifically want to have included, let me know. If you want, I'll put a link on your profile, so people can make direct contact (via LinkedIn, Xing, facebook, etc).

I don't think I can put it on a page here (can I?) so may hvae to host it on Majendi.com or majendi.net.

Supply and Demand

Spain just called
so did Switzerland
and Sweden
London too (twice)
oh, so did Amsterdam
and of Course there's Munich
not forgetting Wiltshire

There's lot's of work out there

And there's not that many OBI / Siebel Analytics specialists either. A few are catching up, but I know of about 5 truely experienced consultants in the market.

So why, oh why do companies think they can get someone who is skilled for 800 Euros per day??? If you have the skills it's because you have invested in a risky market (come on Oracle SELL MORE), and you have some intelligence.
I am actually beginning to think that companies prefer a cheap rubbish job. Come on prove me wrong.

If you are a consultant. Don't take a low rate, don't let the agency take a huge cut and do Learn the product inside out. The success of OBIEE depends upon succesful implmentations.

If you are a company (or consultancy) looking for someone, let me know and I'll put you in touch with good consultants. I'm not an agency but I can probably give you some good advice and screen out the bluffers.

I know most of the companies that are installing OBIEE so if you are looking for your next contract, let me know and I'll put you in touch with project managers.

In fact, I think I'll put the details of projects in my BizIntel yahoo group. Come on, lets get this market working properly.


and the bad news...
We just had a second rejection for a Work Permit application to bring in a skilled worker from South Africa. Seems the government is happy for our work to disappear offshore, and let the skills shortage in the UK continue to hold back small copanies like ours.

If you know how I can get hold of more decent staff I would love to know!!

Is there a way to get people legally working in this country? How does IBM, Accenture and the offshore copanies do it?

or

Does anyone have any idea how some people are able to buy HSMP tickets?!!!

Cluster ....

It appears that there is a significant change that I had overlooked in the new OBI 10.1.3.2, compared to the Analytics 7.8 version.

I had noticed that there was a new webcat structure, that was easy, but one of our contacts spotted that there is a new way of clustering the new Webcat.

Previously, each Webcat server (BI Presentation server) had it's own copy of the webcat file, held within the Data folder.
If you had two or more webcat servers they would syncronise the contents of the webcat using a utility - something that did not work very well.

Now you have one webcat, irrespective of how many web servers you use. They all point to the same webcat.
This neatly solves the problems you get with Syncoronisation, but introduces one significant flaw - a Single Point of Failure.

What do you do? Put your webcat on a SAN, which has all the RAID you can get. Back up the whole webcat folder every night - obviously!
Now take snapshots of the webcat throughout the day, but be very careful how many you take. Too many will slow the system down.

One thing I have always felt though is that you should cluster for Customers' High Availability requirements NOT for performance.

The majority of performance issues should be dealt with by database design, prudent Caching (with seeding), adequate memory, and ETL design. Only when these have been worked through should you look for that extra 5% from clustered servers.

Long live the King

Siebel Analytics is Dead, long live Analytics.

Actually it's not, it's still a damn good product, but the son of Analytics, OBIEE, is the new King.

Why?

Because I'm now having fun without Siebel ;-)

The new world looks like this:

An Apex application is the portal.
Identity management is by OIM (OID), managed by the Apex aplplication.
SSO uses OID to authenticate users.
Links on the portal, to your dashboards and Answer subject areas.
ETL by OWB
Database design by YOU, customise as you like.

Is the grass greener, oh yes.



Of course, Elvis is still the real King

Mad Cowes

All quiet here due to me being on holiday.

We're having a fantastic week in Cowes.

Best of all we are leading the fleet going into the last day.

Overall Results

Help!

Help!, we need somebody, Help, not just anybody, Heelp!!

Can you tell I've been listening to the Beatles tonight?

Anyway, we really do need more Analytics people. We have OBI and Analytics work coming out of our ears, so if you are looking, or know someone with Analytics then please get in touch. Now.

We need all levels, experts who want to contract through to juniors with one project who want to work as a permanent in the UK. (Work permits can be arranged).

Hardly enough time to work on the book. But don't worry it is progressing.

By the way, do you know how how the get totals working in a report that has TopN (or BottomN) in? Just go to the function dialogue for the field and set Totals to 'None'

Catching up

As I have been in hiding on a secret client site (with no access to the internet) for a while, I thought that I would go for a large blog today.


To start with, there is some new functionality in 10.1 that you should know about. One feature is called a Presentation Variable. Like repository based variables but it is created in the BI Presentation system.

Bascially you set it up from a prompt. Once set it can be used all over the place, but my favorite is the Title of a prompted report, or column of a prompted report.

Try this

On the prompt, set a variable, which can then be accessed in the Title of the report.
For example, if you select a County of 'Wiltshire in a prompt, you set a variable name called VAR_COUNTY,
then in the Title you can display 'Details for Wiltshire' by changing the title to: Details for @{VAR_COUNTY}{All Counties}.

Neat eh?

In the good old days (last year!) we had to rely heavily on False Titles to perform the above. These may still be useful today. These use Narratives in reports to create what loks like a title. The report uses the same dashboard prompt as the report it is presented with. Using the @1 syntax you can present the value in the column, the there have a title which says something like 'Sheep in Wiltshire'. Formatted properly it will look like a title. Place it above the query in the same section. Viola.
Now I just tend to use the Section names as the titles.






I started using some Oracle dev tools this week, and I'm actually beginning to like them. Call me fickle but I have to say that I may be throwing out TOAD and starting to use Oracle SQL Developer instead. The main reason is that it is free!!






Having a quick look through my emails the other day I came across this message.

Someone asked the following question


Hi,
We have a requirement to switch between the DBs based on the user login. We have two identical/similar dbs. But based on the users, the connection should switch.
Ex: user1 should see the data fram DB1 and user2 should see the data from DB2. Our plan is to keep a single stream of Physical, BMM ,Presentation catalogs and Webcat. Is this possible through Session variables. If yes, how?


Puna replied with this excellent answer


1) Create a table "db_details" in any db with the following details:
Login_Name dbname dblogin dbpassword

2) Populate this table as per your requirements. Create a connection pool in Physical layer which connects to this table (via database)

3) Create three Non-System Session Variables: dbname,dblogin,dbpassword. Create an initialization block with the following SQL Query:
select dbname,dbuser,dbpassword from db_details where Login_Name=':User' and polplute the the above created variables.
Set the connection pool of the initialization block which was created in step 2.

4) Now for the connection pool for which dynamicity is required as per the logged in user, in connection pool of that database in physical layer set the the following properties to:
Data Source Name: VALUEOF(NQ_SESSION.dbname)
User Name: VALUEOF(NQ_SESSION.dbuser)
Password:VALUEOF(NQ_SESSION.dbpassword)

Make sure if you are using ODBC or DSN's then DSN's with the name "VALUEOF(NQ_SESSION.dbname)" already exist in the system.
So now you will be able to switch DB's based on the Login_Name.
Hope this helps.


Nice one Puna.

If you read this (or know them) please send me your details and I'll invite you to our OBI Developers Forum.

SE One is here

Oracle have officially launched SE One - Like Siebel Analytics only cheaper.

This is the pricing package we have all been waiting for. There is no excuse for any company to not buy Analytics. This can be used for what Analytics is good at => RAD (DSDM) warehouse projects. Finance departments should take a really good look at replacing their Access Databases with this.

You'd think I had shares in Oracle (I Don't)!

Freedom of the City

I had a great day today. I had to go to the Camberlains court and swear allegiance to the Queen and to the Lord Mayor. We (my wife and I) were then granted the Freedom of the city of London.
I can now drive sheep over tower bridge.

Interesting Note from Oracle

This note was published today. It may explain the questions I have been getting.

"The Standard Cost General table (W_STANDARD_COST_G) and the Exchange Rate General table (W_EXCH_RATE_G) are general reference tables.

Both tables have surrogate keys (ROW_WID). But unlike dimension surrogate keys, these surrogate keys are not referenced as foreign keys by any fact tables. Therefore the general tables do not participate in the star schema. They are not designed for use in reports and queries.

The general tables are intended for use as lookups during Extract-Transform-Load (ETL). For example, the Standard Cost General table provides cost information for a particular product in a particular inventory. The cost information will then be stored in the fact table directly. Similarly, the Exchange Rate General table provides the exchange rate between a pair of currencies for a specific day, given the exchange rate type.

The following are some WIDs in the general tables. They are not necessarily populated and they are not intended for use. These columns are:

W_STANDARD_COST_G.PRODUCT_WID
W_STANDARD_COST_G.CREATED_BY_WID
W_STANDARD_COST_G.CHANGED_BY_WID
W_EXCH_RATE_G.CREATED_BY_WID
W_EXCH_RATE_G.CHANGED_BY_WID

If you need to have a cost dimension, you need to design a different table. It is not recommended that you alter the Standard Cost General table for this purpose. "

A typical question

Please keep sending in your questions, it's interesting to see what challenges you guys (and Girls - Vicky!) face.


Here's a recent one


Hello Adrian,

I need little help.

Our company is implementing Oracle BI 10.x. We don't have much experience in Siebel Analytics/OBI.

We have few fact tables e.g. W_SALES_PICK_LINE_F, which we need/wish to extend. We are not sure about which methodology we should implement.
When we talked with few SA experts they mentioned we need to extend based on ROW_WID. Well, this column doesn't exists anymore in many fact tables, so currently we are thinking of creating ROW_WID on this F table manually and then create WC_SALES_PICK_LINE_FX and take these two tables in physical layer of RPD.

Additially, we need to create few Informatica mappings, again SA experts pointed out to use Image tables. Our data source is Oracle Applications, I don't have much idea about Image tables, but clearly there is not S_ETL_I_IMGAGe or so tables in Oracle Apps

Please guide us as how to proceed on these two issues.

Thanks in advance


and my answer

I am surprised to hear that ROW_WID has been removed from standard vanilla tables. I don't think your system will work without the ROW_WID field. Add the field back in quick! :)

My advice is to extend an existing table, not to create _FX tables. Providing you keep good control on your alter table scripts there are no issues with extending vanilla tables.

Take a copy of the vanilla mappings and customise these in your custom mappings folders. Do not update the vanilla mappings in place - they will be over written in an upgrade.

You can create your own image tables in the oracle db. The alternative is to use a last modified field in the table being imported.

You only need to create immage tables where there is lots of data, typically more than one million rows


Please can you send me more details on the project. It's good to understand where you are coming from, if you send me your rpd I can provide some feedback

Analytics Projects - Who wants one?

Whilst looking around for my next client I realise that we, as Analytics consultants, need to talk to each other more. Whats more, the consultancies and clients really need a place to go for reliable, experienced Analytics specialists.

I was discussing one new project with Haider and it turns out he worked on it before. It's a small world, and Siebel Analytics has a relatively small client base (my wild guess is 400-500 UK clients, half of which are active).
I know about 75 Analytics consultants. There are probably another 100 out there, perm employees, that may one day become freelance and pop up in the Majendi radar.

At the moment the Agencies have a good control on the Market. There are some that put out adverts for non existant jobs. They are useful to the liquidity of the market and some work hard for their cut of you pay. Just be careful they are not taking too much, the best ones have a fixed percentage with their clients. More than 15% is excessive.

So how do we help consultants? We probably should look at the networking capabilty that's out there, linkedIn, Xing, ecademy, Yahoo, etc, and perhaps set-up an OBIEE/Analytics forum. There we could share thoughts on prices to charge, new projects, help needed, technical stuff, etc. I have started one group on Yahoo, if you fancy joining in, let me know - it's invite only. I'm not sure if this helps the clients though.


Any thoughts?

On the subject of rate. You are what you charge. If you charge a cheap rate, your will be percieved as local quality, if you charge a premium rate you should deliver a premium level of service.
What are those rates? My view is that a certified consultant with 2 years (min 3 projects) Analytics consultant should be charging a minimum of 600 GBP per day. Lead consultants, with 7+ project should be GBP 750 per day. The consultancies will obviously need to charge clients a higher level. Some of the cheaper ones are charging 6-700 euro per day, the better ones, with good experience and efficient work, will be charging 900 plus.
One client I saw recently had a greatdeal with a low cost provider, the problem was they didn;t trust the work, and the estimate for time was nearly double what was really required. The client ends up paying nearly the same for inferior work. Somehow we need to educate that quality is very important to them, not cheapness.
