Archiving only compressed InfoCubes?

Hello Colleges,
We have an InfoCube with 5 Mill Records. If I try to select a daterange for Archiving, I get allways the error the request is not compressed. I could not find in any document any record size when it has to be compressed. Is it a generall restriction, which is never mentioned in a document. Does anybody has experince with archiving and had also this problem?
Thanks for the help
Henning

Hi,
It is recommended to archive only fully compressed InfoCubes as you want to ensure that you do not archive data from requests while they are being loaded.
In addition, if you InfoCube has a non-cumulative key figure, there is a hard check to ensure all requests are compressed first before an archive job can execute.
I hope this helps,
Mike

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.

Compress infocube with zero elimination

Experts, Is that true you should always check "with zero elimination" when you compress infocubes? I was reading the famous SAP doc "How to Handle Inventory Management Scenarios in BW", the screen shots for cube compression does not have that checkbox checked. Does anybody know why?
Thanks!

Hello,
Using the zero elimination the entries where all key figures are equal to zero are deleted from the fact table during compression. You don't want that in Inventory Management.

Aggregate = compress infocube?

I ve heard that an aggregate has E and F fact tables , which It's a property of compressing infocubes.
so what's the difference between aggregate and compress infocubes?
Joseph

whenever we have huge volume of data , then its prefarable to use aggregate, there are some other parameters as well.
Pls do refer the following link

Archive only 3 batch classification tables

Hi Gurus,
I want to archive only AUSP, KSSK and INOB tables.
Is there any way that i can archive only those 3 tables? (i.e. Without archive any other tables which links to the particular archiving object.)
Also what are the prerequisites ( technically complete production orders, close purchase orders) for that?
Thanks & Best Regards,
Sandun

there is no archiving object that can archive records from these tables without archiving records from any other leading table.
These tables are not only used for batch classification, they hold values for several other classifications as well, they are just the central tables of classification system.
You have to archive the business object, e.g. MM_SPSTOCK for batches, to get dependend records from tables AUSP, KSSK ... archived too.

Archive Log Compression

Hi
There is a feature that allows us to compress archive logs. This is set using "ALTER DATABASE ARCHIVELOG COMPRESS enable;"
What I need to know is
1) Which versions of oracle supports this.
2) Has anyone experienced any drawbacks using this.
Thanks

This is what I got back from ORACLE.
Generic Note
Hi,
The archive log compression feature was withdrawn from the release before the oracle 10g production release.
It may appear to function as expected, but it is not yet supported and is intentionally not documented.
Bug 3464260 - ALTER DATABASE ARCHIVELOG COMPRESS ENABLE/DISABLE IS MISSING IN 10G DOCS
Status: 92 - Closed, Not a Bug
- An Enhancement Request been created Bug 6780870 GENERATION OF COMPRESSED ARCHIVELOG FILES to ask
if this functionality will be offered in a future release which is yet not been update by development..
In other words, The SQL statement ALTER DATABASE ARCHIVELOG COMPRESS enable is possible, but indeed
currently unsupported and undocumented even in Oracle Database 11g
Archive compression was a planned new feature for 10G, but unfortunately it was withdrawn and it is still
not available in 11g .This feature is expected in future releases.
Please let me know if that answers your questions .
Regards,
One more question.
We are running windows, I know someone mentioned gzip for linux, can we use that for windows compresssion, or will winzip or winrar or any other compression tool work.
Thanks

Archiving Only option in Output Control

Hello Gurus,
There is an option Archiving only in output type. Could you please provide us the use of it and how exactly it works. Wht requirement needs to be used while adding this output type in procedure.
Points wud be rewarded generously for apt answers.
Thanks and Regards,
Pavan P.

hi,
The document type to be used can then be entered in the Storage system title of the message type The Storage mode selection field controls whether a message is outputted, stored or outputted and stored. The entry of a document type is only necessary in the last two cases.
Follow this steps
Tcode:NACE
let take example of BA00 order confirmation
1.select V1:sales--->click output type ikon which is in the top> now inthis screen double click BA00> here click stoarge system tab>in the stoarge mode select 2 Archive only--> save
but y u want to archive the document while outputing,please revert

Bad reporting performance after compressing infocubes

Hi,
as I learned, we should compress requests in our infocubes. And since we're using Oracle 9.2.0.7 as database, we can use partitioning on the E-facttable to still increase reporting performance. So far all theory...
After getting complaints about worse reporting performance we tested this theory. I created four InfoCubes (same datamodel):
A - no compression
B - compression, but no partitioning
C - compression, one partition for each year
D - compression, one partition for each month
After loading 135 requests and compressing the cubes, we get this amount of data:
15.6 million records in each cube
Cube A: 135 partitions (one per request)
Cube B: 1 partition
Cube C: 8 partitions
Cube D: 62 partitions
Now I copied one query on each cube and with this I tested the performance (transaction rsrt, without aggregates and cache, comparing the database time QTIMEDB and DMTDBBASIC). In the query I selected always one month, some hierarchy nodes and one branch.
With this selection on each cube, I expected that cube D would be fastest, since we only have one (small) partition with relevant data. But reality shows some different picture:
Cube A is fastest with an avg. time of 8.15, followed by cube B (8.75, +8%), cube C (10.14, +24%) and finally cube D (26.75, +228%).
Does anyone have an idea what's going wrong? Are there same db-parameters to "activate" the partitioning for the optimizer? Or do we have to do some other customizing?
Thanks for your replies,
Knut

Hi Björn,
thanks for your hints.
1. after compressing the cubes I refreshed the statistics in the infocube administration.
2. cube C ist partitioned using 0CALMONTH, cube D ist partitioned using 0FISCPER.
3. here we are: alle queries are filtered using 0FISCPER. Therefor I could increase the performance on cube C, but still not on D. I will change the query on cube C and do a retest at the end of this week.
4. loaded data is joined from 10 months. The records are nearly equally distributed over this 10 months.
5. partitioning was done for the period 01.2005 - 14.2009 (01.2005 - 12.2009 on cube C). So I have 5 years - 8 partitions on cube C are the result of a slight miscalculation on my side: 5 years + 1 partion before + 1 partition after => I set max. no. of partitions on 7, not thinking of BI, which always adds one partition for the data after the requested period... So each partition on cube C does not contain one full year but something about 8 months.
6. since I tested the cubes one after another without much time between, the system load should be nearly the same (on top: it was a friday afternoon...). Our BI is clustered with several other SAP installations on a big unix server, so I cannot see the overall system load. But I did several runs with each query and the mentioned times are average times over all runs - and the average shows the same picture as the single runs (cube A is always fastest, cube D always the worst).
Any further ideas?
Greets,
Knut

How to delete the data in the compressed infocube

hi, bi gurus
we are facing a problem in inventory management the info cube in BW production
normally every time inventory cube gets compressed that means the data will be moving to F fact table to E fact table
now the problem is we are having some bad data for latest five requests in this cube as we all know compressed data
can't be delete by deleting request in the request tab the only way is go for selective deletion but i don't find any selective
option in the cube we are PSA data for that five request which having correctdata please help how to delete the bad data in the
info cube and load the correct data which we are having in PSA
Thanks
Joe

Hi André
Thanks you for ur answer
what i am telling is their is an option for selective deletion for inventory cube
but i don't find any specific option to delete the data that means like calendar day like that
i hope you got my question.
hi Saveen Kumar,
Thank you again
we are using 3.xx flow if we do the request reverse posting for all the 5 requests which has updated incorrect data
next we need to do compression also or not
and how to reload the data from PSA to Infocube becuse if request still avaliable in info cube it will not allow me to do that
can you please tell me detail how to proceed in step by step this is first time i am doing request reverse post and i have to do it production please tell me
Thanks in adavance
Thanks,joe

A question on different options for data archival and compression

Hi Experts,
I have production database of about 5 terabyte size in production and about 50 GB in development/QA. I am on Oracle 11.2.0.3 on Linux. We have RMAN backups configured. I have a question about data archival stretegy. To keep the OLTP database size optimum, what options can be suggested for data archival?
1) Should each table have a archival stretegy?
2) What is the best way to archive data - should it be sent to a seperate archival database?
In our environment, only for about 15 tables we have the archival stretegy defined. For these tables, we copy their data every night to a seperate schema meant to store this archived data and then transfer it eventualy to a diffent archival database. For all other tables, there is no data archival stretegy.
What are the different options and best practices about it that can be reviewed to put a practical data archival strategy in place? I will be most thankful for your inputs.
Also what are the different data compression stregegies? For example we have about 25 tables that are read-only. Should they be compressed using the default oracle 9i basic compression? (alter table compress).
Thanks,
OrauserN

You are using 11g and you can compress read only as well as read-write tables in 11g. Both read only and read write tables are the candidate for compression always. This will save space and could increase the performance but always test it before. This was not an option in 10g. Read the following docs.

Online Archive only visible in Outlook 2010 after OWA logon

Dear.
We implemented Exchange 2010 native archiving. We created our own retention policies, applied them to the mailboxes and archiving started successfully exactly as we want it.
We’re using Outlook 2010 clients with both: cached and non-cached mode. The strange thing is that for the online archive to be visible in outlook, the user needs to logon to OWA
first and only once. Afterwards, online archive stills visible in Outlook 2010.
Is there any other way to make the online archive visible without forcing the user to do a one-time logon to OWA?
Thanks for the feedback.
Regards.

How do I archive only the last Time Machine backup?

Hi everyone
So i've done a "clean reinstall" of Lion and restored some of my files manually from TM backup located on an external hardrive by dragging them over via Finder. Now I want to delete all old TM backups on my ext hardrive and only save the last backup (the one I did before the Lion reinstall).
If I save the latest TM backup folder (named ~/Backups.backupdb/~/2012-04-11-233905) and delete all the older ones – would that save my entire last backup? Or does that folder contain aliases to other files in previous backup folders? i.e. does the last created Time Machine backup folder contain all files from the last backup?
Please help.

Linc, you don't seem to understand my problem – i want to start my TM backups from scratch from my "new" computer and archive the last backup I did on my "old" one. I don't need all the other backupped versions from my "old" computer – just the last backup which I want to archive.
My question is still:
Is there a way to archive my entire last backup (and delete all the previous ones)?

CiscoWorks: Why all devices Sync archive only partially successful.

Hi,
Whenever we sync archive a device, its always partially successfull only, and when we click partial successfull , below details appears. We have 4000 devices and all are only partially successful only Below details are from partial successful device, it has the vlan. dat and before it was working ok.
*** Device Details for Device1 *** Protocol ==> Telnet Selected Protocols with order ==> SSH,Telnet,TFTP,RCP,HTTPS

I am using LMS 3.2.1

Yes you are right that we have restore from backup and since then this problem occurs. We have uninstall the CiscoWorks from c: drive and install it on e:drive, due to high disk utilization issue on c: drive.
I have checked the
RME > Administration > Config Management > Archive Management > Archive settings and setting is already e: /CIS~1/files/rme/dcma,
Also from dbreade, by executing the sql "select * from Config_Device_Archive" in rmeng, I can see that some file location is C:drive and orther files location is E: drive, so I have run the below sql to correct it, although it executed correctly, by I can see that Config_Device_Archive table that still some devices location is c:, others is e: drive.
update Config_Device_Archive set
location=replace(location,'C:\\PROGRA~1\\CSCOpx','E:\\CAPCIS~1')
Please advice, that how to resolve this issue.
Thanks
