| Answer | 1) Each version have some licence perion and Licence for 5x end by 2007
december i guess. Also some enhanced features available in the latest versions.
2) If u want to convert 5.x Deski to XI Deski just open the report in XI.Nothing to
be done extre. But its safe to have a backup of 5 seperatly. Then you can check
the data by running the reports in Both Versions.
If u want to covert to Webi use migration tool provided in XI. Here you might
face some allignment and formating problem will arise.
3)Send your mail id. I will send materials regarding migration  |

| Answer | you could use an event wait task in the workflow as the
first task. Once the event wait task detects the file in
the specified folder all other sessions tasks wil run.
alternatively you could use unix commanda in the command
task.  |
| Lakshmi |
| |
| |
| Answer | You can use a pmcmd command to trigger the workflow using a
shell script. You can also use the event wait task
described in the above answer.
Alternately you can use an UNIX script to work as an active
listener. This will trigger the workflow once the presence
of file is detected in a specific directory. A schedular
tool also will be useful.
If you could describe more about your requirement one can
add more thoughts into it.  |

What do mean by cluster mechines and SMP and MPP..?

Question Submitted By :: Ram |

© ALL Interview .com |
| Answer | symmetric multiprocessing or SMP involves a multiprocessor
computer-architecture where two or more identical
processors can connect to a single shared main memory. Most
common multiprocessor systems today use an SMP
architecture. In case of multi-core processors, the SMP
architecture applies to the cores, treating them as
separate processors.
SMP systems allow any processor to work on any task no
matter where the data for that task are located in memory;
with proper operating system support, SMP systems can
easily move tasks between processors to balance the
workload efficiently.
Massive parallel processing (MPP) is a term used in
computer architecture to refer to a computer system with
many independent arithmetic units or entire
microprocessors, that run in parallel. The term massive
connotes hundreds if not thousands of such units. Early
examples of such a system are the Distributed Array
Processor, the Goodyear MPP, the Connection Machine, and
the Ultracomputer.
Today's most powerful supercomputers are all MP systems
such as Earth Simulator, Blue Gene, ASCI White, ASCI Red,
ASCI Purple, and ASCI Thor's Hammer.
In this class of computing, all of the processing elements
are connected together to be one very large computer. This
is in contrast to distributed computing where massive
numbers of separate computers are used to solve a single
problem.
The earliest massively parallel processing systems all used
serial computers as individual processing elements, in
order to achieve the maximum number of independent units
for a given size and cost.
Through advances in Moore's Law, single-chip
implementations of massively parallel processor arrays are
becoming cost effective, and finding particular application
in high performance embedded systems appplications such as
video compression. Examples include chips from Ambric,
picoChip, and Tilera.
Cluster
A computer cluster is a group of linked computers, working
together closely so that in many respects they form a
single computer. The components of a cluster are commonly,
but not always, connected to each other through fast local
area networks. Clusters are usually deployed to improve
performance and/or availability over that provided by a
single computer, while typically being much more cost-
effective than single computers of comparable speed or
availability

| Answer | SMP.)SYMTERRIC MULTI PROCESSING SMP:-ALL PROCESSORS WILL BE
USING SAME MEMORY DISK,MEMORY BUFFERS.HERE PROCESSCORS WILL
BE WAITING FOR DISK I/O PROCESS.
MPP:MASSIVELY PAPALLEL PROCESSING.)HERE EACH PROCESSOR WILL
BE HAVING IT'S OWN MEMORY AND MAMORY DEVICES,PHYISICALLY
ALL THIS PROCESSORS WILL EMBEDDED IN A SINGLE CABIN.AND
WILL COMMUNICATE THROUGH SHARED MEMORY BUSES.
CLUSTER M/C:) SAME AS MPP ,BUT PHYSICALLY THIS M/C ARE
HOUSED IN DIFFERENT CABINS AND WILL COMMUNICATE THROUGH

| Answer | A table can't have two primary key.  |
| Rajiv Senapati |
| |
| |
| Answer | Primary key
============
1. A table should have only one primary key
2. More than one column can consist of a primary key – upto
64 columns
3. Can not be NULL values (missing values)
4. Should be unique values (no duplicate value)
Foreign key
============
1. A table may have zero or more than that upto 32 keys
2. More than one column can consist a primary key – upto 64
columns
3. Can have NULL values
4. Can have duplicate values
5. There should be a corresponding primary key in the
parent table to enforce referential integrity for a foreign
key  |

| Answer | OLAP - Online Analytical Processing, which deals with
analysis of data. It has to deal with historical data too (
for analysis purpose) Not updated frequently. If required
bulk update is allowed.
OLTP - Online Transactional Processing, which deals with
transactions. For e.g. withdrawals at ATM machines. It
involves many transactions. The databases have to be updated
more frequently after the successful completion of a
transaction.  |
| Jansi |
| |
| |
| Answer | i am agree with the above answer.olap is denormalized and
oltp normalised  |
| Vams_gk |
| |
| |
| Answer | OLTP
* Is the E-R modleling,there are more concurrent users,
* It contains normalized tables so there is no redundancy.
* More tables,Joins and less Indexes,
* It stores daily transactional data
* It stores very less data
* It contains mainly current data
* INSERT,UPDATE,MODIFY can be applied on OLTP.
* Performace will be high
OLAP
* It is the Dimensional Modeling
* It contains Denormalised tables there will be redundancy.
* Less tables,Joins and more Indexes
* It stores operational data
* It contains Historical and Present data
* only SELECT clause is applied on OLAP
* It stores very Huge data
* Performance will be low compared with OLTP  |

| Answer | There is only one universe in terminology of BO, but there
may be many situations based on the usage, where we can
classify the universes as-
1. Depending on type of data universe objects mapping
a. Ad-hoc (personal data) – The Universe created for a
personal usage is called Ad-hoc Universe and these are not
shared with anybody else.
The reports created using these universes are called Ad-hoc
Reports and generally users have the rights to store the
reports in the Inbox. Ad-hoc reporting is a user friendly
feature designed for all levels of users. Custom reports
are created using queries.
b. Non Ad-hoc (corporate data) – The universe created
for a corporate usage is known as Non ad-hoc Universe these
are sharable Universes and reports created from these can
be viewed by all the users.
2. In linking universes scenario
a. Core universe (Kernel or Master universe) – The
Universe created and used with another universes for the
reusability of the components.
b. Derived universe – The Universe created using Core
universe and there own required components.
3. Depending on universe parameters.
a. Secured universe.
b. Personal universe.
c. Shared universe.  |
| Zeenat |

| |
| Answer | universes are 3 types : 1)simple universe
2)complex universe 3)dervied universe
In metric universe aggregate summary is disable. so metric
universe is not used
in simple uni while the aggregate summary is enable. and
also it generates the summary.

| Answer | By having multiple contexts you can utilize the 'multipass'
sql feature. Multipass: Breaking one large SQL into
multiple SQLs.If you are using the star schema with two or
more fact tables,and you enable this feature, BO will
automatically generate two or more SQLs (i.e. one SQL for
each fact table object used in the report). Then the
results will be synchronised in the report. For more on
multipass concept please refer to Ralph Kimball's Lifecycle
toolkit (not modelling)book.  |
| Nathan |
| |
| |
| Answer | Because it will be bit confusing for the users to select
which context to use if they don't have the knowledge of
how BO works  |
