Relation between Rollup and compression.

Hi All,
Is there a relation between rollup and compression ? i.e if i compress the cube, will the rollup job be faster ?

Hi,
Thanks for all your replies. Now the picture is crystal clear.
1. A compression job moves data from F table to E table. This is also applicable for aggregates. If you schedule a compression job for a cube, the aggregates are automatically compressed( You can also compress aggregates of a cube without compressing the cube. There are programs avalibale for the same).
2. Assume that you have not done compression . If you load the data to base cube ,it takes more time to create the indexes after loading.
3) Assume that you have done compression . If you load the data to base cube ,it takes less time than 2 point to create the indexes after loading.
On similar lines, if aggregates of a cube are compressed before rollup, then rollup will be faster. This is what exactly I have experienced. I had a cube which had 1000 request. It was never compressed. The rollup job for the cube used to take around 60,000 seconds. I compressed 900 requests. Now the rollup job gets over in 2400 seconds.So the conclusion is the following:
When aggregates of a cube are compressed, the rollup job runs faster.

How to delete the rollup and compress request from the cube

Hi Experts,
I have a requirement, one request was updated into the cube and it was been rollup and then compressed. As the request was compressed so based on request id we cant perform the deletion.
So it is possible with selective deletion. Now before performing the selective deletion do i need to deactivate the aggregates.
Help me out on this.
Regards
Prasad

Hi.........
U hav to deactivate the aggregates................bcoz.........Selective deletion is only possible with uncompressed requests...............ie from F fact table...........after compression data moves from F fact table to E fact table.............. you can't do selective deletion on E fact table.........So first deactivate the aggregates............then do the selective deletion..............then again activate the aggregates..............and do the aggregate filling job manually in RSA1..............but I will suggest u delete the request...............bcoz any how u hav to deactivate the aggregates............and in case of selective deletion u hav to be very particular................if ur load is not taking much time............then delete the request and repeat the load............

BW : Question what is rollup and compress

Hiii Guys ,
I wanted to ask that what do you mean by Rolllup the cube and compress the cube..Why do u need it?what is its significance and how it is done?
Plz let me know.
Thanks & Regards
MAdhavi S Bichakal

Hi Madhavi,
Roll Up :
It is done if our cube has Aggregates. When you update your Cube with fresh data it must reflect in aggregates of that with that fresh data so for this we do Roll Up.
If you do not perform rollup regularly, your report will show old data.
Lets say that you have aggregates on your cube and all requests have been rolled up as of now. Lets say the latest request is 34256...All data is available for reporting now upto request 34256.
Say you loaded your InfoCube again 4 times. These 4 requests are NOT available for reporting if they are not rolled up, even if the query uses aggregate OR NOT. So, if you run a query you will only get data upto request 34256, which was the last rolled up request.
So, if you have aggregates, its a best practice to rollup into the aggregates at the earliest for your reports to show latest data, usually as a last step in the same process chain that you use to load your InfoCube.
Compression:
InfoCube has 2 fact tables: E and F. F table has request number associated with each data load. When you compress the cube; data from F table is moved to E table. But request id is deleted from the data loads. Hence the data is stored in a compressed form.
Advantage of cmpression is better query performance.
Disadvantage: Once you move the data from F to E table; you cannot delete the data depending on the request number, you will have to use Selective deletion
Hope it helps.

Rollup and Compression in PC

Guys, Let's say If I have an infocube which has aggregates created on it. In a process chain how would the data flow look like?
Is this one correct??
START > DROP INDEXES > LOAD > CREATE INDEX > Roll Up of Filled Aggregates/BIA Indexes
Also what about the compression?
START > DROP INDEXES > LOAD > CREATE INDEX > Compression of the InfoCube
Thanks,
RG

Hi,
Yes, this is the process.
but regarding compression, it comes after roll up of aggregates(if aggregates exist)
hope this helps

Rollup and Datamart concepts for compressed cube

Hi all,
I loaded the data into cube and i compressed it ( collapse ),
Then I have 2 questions
1. Can i use the Rollup option now?
2. Can I load the data into another cube by using the compressed cube?
good answers are rewarded
Regards
Ram

hi sri
Its not like we cannot do rollup before compression. You are right we do rollup to fill the aggregates. When you will do compression the request id will be deleted and the data will move from F table to E table. There will be no requst id at all.
We do rollup based on Request only. If there is no request how can u do rollup. the same requst will not be availabe for reporting if u dont do the Rollup to aggregates.

Aggregation, archiving and compression

Hello,
How important is it to begin the aggregation, archiving and compression setup before go-live of a BW-environment?
Is it possible to do this after the cubes have been filled?
We are going live after the weekend and haven't given this much consideration... The plan is to start thinking about this now, just after the go-live...
Need I worry?
Best regards,
Fredrik

hi Fredrik,
aggregate, compression and archiving are done to improve performance.
yes, we can do compression and rollup(after aggregate created) after cubes have been filled, and normally we will include this process in process chain, there are process type for this. compression and rollup are done after daily data filled in infocube.
normally you can set cube for compression.
aggregate is created based on query run examination.
check the aggregate on query performance doc.
Business Intelligence Performance Tuning [original link is broken]
archiving, after go live we won't need archiving so soon,
archiving is done to historical data that not used.
you can start include the compression in process chain,
and evaluate you most used queries and see if aggregate needed.
hope this helps.

Roll up and Aggreagaes and Compression on transactional Infocubes

Hi Frineds,
I want to know about like whether Roll up and Compression is possible or not on Transactional Infocubes?
Please confirm the correct one.
I know this is very basic one but i want exact answer.
Will assign the points.
Thanks in advance.
Regards
SAPSEM

Hi,
of course u can build aggregates, can do compression on transactional info cubes because transactional info cube is also a basic cube with planning allowed.
as we can do loading for transactional cube we can build indices, we can maintain aggregates do compression to improve query performance.
go into manage of the transactional cube u can find everything same as basic cube.
same performance tab,same rollup tab, same collapse tab.
assign points if it helps.
thanks,
pavan.

Aggregate Roll Up and Compression

HI,
I am familiar with the basics of Aggregate Roll Up and Compression.
What I need to know is which one should follow the Other. I mean, should Aggregate Roll Up done before Compression or Vice-Versa ? What r the advantages of doing it in a particular order ?
Regards
Arjun

Hi Arjun,
Aggregate rollup must be performed befor the compression, it should not be vice versa.
The reason is, aggregate rollup is performed on a request basis, it needs request ID to rollup the data. Compression of the request in cube leads to loss of request ID as the data is compressed. Then the rollup is not possiable.
Please let me know if you need any more information.

Pankaj

Aggregation,Roll up and Compression

please answer me the following question
what are the functions of aggregation,roll up aggregation and compression in an infocube....what is the relevance of zero factcount?

Hi Manoj kumar,
Aggregates.
Aggregates are for performance purposes. when u cretae an aggregate based on certain charecteristics u have some indices generated based on this set of charecteristics,
when u query based on this these set of charecteristics, the data retrival will be fast. mostly aggregates are created for set of charecteristics that would be often used for querying.
u can find out which are most used charecteristics from the transaction RSRD. this would suggest you on which charecters u can create aggregates.
if u unnecessarily create aggregates on less frequently used aggregates its gonna consume disk and unnecessary time.
Rollup.
Rollup is for filling the aggregates. its basically to recreate the indices for the aggregates after each time u load data to an infoobject.
rollup should be done after each time u load a target which has aggregates.
Compression
Compression is a process in which the data which is arranged on the basis of request number gets arranged on tha basis of keys.
its mainly to save disk space.
when u compress the requests , the records will be unlinked from their request numbers and and u can never delete any data based on request number.
Hope this helps you.

Ranjith

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

ROLLUP AND CUBE OPERATORS IN ORACLE 8I

제품 : PL/SQL
작성날짜 : 2000-06-29
========================================
ROLLUP AND CUBE OPERATORS IN ORACLE 8I
========================================
PURPOSE
ROLLUP 과 CUBE Operator에 대해 설명하고자 한다.
Explanation
ROLLUP operator는 SELECT문의 GROUP BY절에 사용된다.
SELECT절에 ROLLUP 을 사용함으로써 'regular rows'(보통의 select된 data)와
'super-aggregate rows'(총계)을 구할 수 있다. 기존에는 select ... union select
를 이용해 구사해야 했었던 것이다. 'super-aggregate rows'는 'sub-total'
(중간 Total, 즉 소계)을 포함한다.
CUBE operator는 Cross-tab에 대한 Summary를 추출하는데 사용된다. 모든 가능한
dimension에 대한 total을 나타낸다. 즉 ROLLUP에 의해 나타내어지는 item total값과
column total값을 나타낸다.
NULL값은 모든 값에 대한 super-aggregate 을 나타낸다. GROUPING() function은
모든 값에 대한 set을 나타내는 null값과 column의 null값과 구별하는데 쓰여진다.
GROUPING() function은 GROUP BY절에서 반드시 표현되어야 한다. GROUPING()은 모든
값의 set을 표현합에 있어서 null이면 1을 아니면 0을 return한다.
ROLLUP과 CUBE는 CREATE MATERIALIZED VIEW에서 사용되어 질수 있다.
Example
아래와 같이 테스트에 쓰여질 table과 data을 만든다.
create table test_roll
(YEAR NUMBER(4),
REGION CHAR(7),
DEPT CHAR(2),
PROFIT NUMBER );
insert into test_roll values (1995 ,'West' , 'A1' , 100);
insert into test_roll values (1995 ,'West' , 'A2' , 100);
insert into test_roll values (1996 ,'West' , 'A1' , 100);
insert into test_roll values (1996 ,'West' , 'A2' , 100);
insert into test_roll values (1995 ,'Central' ,'A1' , 100);
insert into test_roll values (1995 ,'East' , 'A1' , 100);
insert into test_roll values (1995 ,'East' , 'A2' , 100);
SQL> select * from test_roll;

1995 West A1 100
1995 West A2 100
1996 West A1 100
1996 West A2 100

Release 8.1.5 PL/SQL에서는 CUBE, ROLLUP 이 지원되지 않는다. 8i에서는 DBMS_SQL
package을 이용하여 dynamic SQL로 구현하는 방법이 workaround로 제시된다.
Ordacle8i에서는 PL/SQL block에 SQL절을 직접적으로 위치시키는 Native Dynamic SQL
(참고 bul#11721)을 지원한다.
Native Dynamic SQL을 사용하기 위해서는 COMPATIBLE 이 8.1.0 또는 그 보다 높아야
한다.

RE: Cleaning and Compression Environment Repository

Mark,
I'm not sure what I did wrong the first time. I thought I
covered all the bases, but just to be certain, I did the
whole sequence again and now it works.
Before, I did have problems restarting the environment,
because the repository was locked. I had to kill a
hanging process to solve the problem. Most likely
it was this process that was interfering with my original
attempts.
With this script, you offered some very usefull infor-
mation. Where did you get it? Like I said in my
first posting, I couldn't find any documentation.
The "help" function of "envedit" doesn't show any of
the commands you used. No way, you stumbled
on this by accident.

Subject: Re: Cleaning and Compression Environment Repository
The script mentioned is the exact sequence of commands that should be
used.
Did you shutdown the environment first? You cannot clean an environment
repository while the environment is online. I know that these commands
work for both NT and Unix environment managers.

Mark,
I'm not sure what I did wrong the first time. I thought I
covered all the bases, but just to be certain, I did the
whole sequence again and now it works.
Before, I did have problems restarting the environment,
because the repository was locked. I had to kill a
hanging process to solve the problem. Most likely
it was this process that was interfering with my original
attempts.

HTTP Headers - enabling caching and compression with the portal?

Has anyone configured their web server (IIS or Apache) or use a commercial product to flawlessly cache and compress all content generated by the portal?
Compression and caching is critical for making our portal based applictions work for overseas users. It should be doable, just taking advantage of standard HTTP protocols, but implementing this a complex system like the portal is tricky, we seem to be generating different values in the HTTP Headers for the same types of files (such as CSS).
We are running Apache so can't take advantage of the built in compression capabilities of the .net portal. We are running the java vervion. 6.1 mp1, sql server 2000 (portal, search, collab, publisher, studio, analytics, custom .net and java portlets on remote server).
Basically our strategy is to compress all outgoing static and dynamic text content (html, CSS, javascript), and to cache all static files (CSS, javascript, images) for 6 months to a year depending on file type.
Here are some links on the subjects of caching and compression that I have compiled:

Hi Scott,
Does Weblogic platform 8.1 supports netscape? We have developed a portal which
works perfectly on IE but it dies in netscape. Is netUI tags not supported in
Netscape?
Pls reply

Netscape 4.x and below have terrible performance with nested tables.
The
problem is not the Portal server but rather Netscape on the client machine.
If IE and/or a recent version of Netscape/Mozilla is not possible then
there are
really only two options:
1) Faster client hardware - not likely to be an acceptable solution.
2) Minimize the number of portlets and the complexity within the portlets.
Neither of these solutions are a great answer, but the 4.7 series of
Netscape is
getting pretty old. Having said that, we've got customers who want to
continue
to use IE 4 :)
Again, though, this problem is, I'm afraid out of our hands. It is the
client
rendering time that is the issue.

pages can take up to almost 30 seconds to load in Netscape 4.7? I knowit is a
very generic question but our customer still uses 4.7 and will notuse the portal
b/c it takes so long to load some of the webapps. What the pages willdo when
loading is that the headers will come up and when it gets to the bodyof the page
it seems to stall and then comes up all of a sudden. For some of thepages it
takes 6 seconds and for others it takes about 24-27 seconds.
We have suggested using IE only but that is not an option with allof the customers
and getting a newer version of Netscape is also out of the question.
Any suggestions would be greatly appreciated.--
