UCCE 10.0 EDMT will reduce database size ?

Hi
We are doing Tech Ref. upgrading CCE 8.0.3 server to CCE 10.0,
Intial HDS DB size is 145GB
after patch upgrade to 8.5, the HDS DB size is 125 GB,
but after EDMT to ver 10.0 the migrated data is 79GB
does something happened in migration towards the new version discarding some data
In EDMT logs everything successfull
In the 8.5 HDS Tables i can see the count is 366 items and for View folder is 443 Items
In the 10.0 HDS tables i can see the count is 343 items and for View folder is 456 Items
Why we see this difference, is it normal, how we got this much reduction in size
Also, there is difference in HDS size between AW A and B too
Thanks

Hello Kanan,
I have installed a Solution Manager 7.1 SP03 system, and I installed using Oracle not max DB.
Right now the system is pretty pristine. The Database allocation is 146GB and of that allocate space I have used about 100GB
My data base size is 146, I do not have a shortage of disk space, and the DB will autoextend should I fill it up.
So my question would be of the 136GB what percentage is used? When you say it is growing, is it extending, or is it just
using more of the allocated space?
I am just now looking at a colleagues Solman 7.1 SP03 system. They have 176GB allocated to the database, but they have 104GB used. Their system has had a fair bit of use, but it is not a production system either, so it doesn't have a real world load on it.
So typically reducing the size of the database, would entail unload the database to a flat file, resizing the database, and then reloading the database. Typically this si a DBA function.
So I am not sure at what point a MaxDB databse would extend if you mean the physical size of the database is getting bigger. Still 136GB wouldn't be considered an unreasonable allocation as my system has 146Gb allocsated to the DB and my Colleague has
176 GB allocated. ButI only used 100GB and they have used many scenarios and has maybe 20 users and only has used 4 GB more than me. So what is the size of the used space verus the allocation?
You can remove various service sessions using report RDSMOPREDUCEDATA, but on a training system, I am not sure how much space that would free up. You can run a DB02 to see the allocation versus what is used, if you are not sure if 136Gb is the allocation or what space has been used. !f 136GB is the allocation, its actually low, and I suspect it is, since MaxDB tends to have a smaller foot print than Oracle. But if it is the space used and not the total allocation, then it seems very high for a training system..
Hope this helps some.

Paul

BW System copy from PRD to DEV - Reduce database size

Hi All
We are in the process of copying our existing Production BW system (3.5) to become a new Development & test system. We want to reduce the database size significantly from 1.4 Tb to about 150 - 200 Gb. We have deleted all cube and ODS data as well as much of the master data but still have much tablespace tied up in monitor entries (eg table RSMONMESS) and IDOCs. All of the notes I read say that we cannot delete from RSMONMESS in a "Prodcution" environment, however we are creating a new DEV system and really need to get rid of monitor entries anyway. So there are two questions:
1. Any idea how we can clear up table RSMONMESS or delete unwanted monitor entries ?
2. How can we delete IDOCs copied from our production system without archiving them ? (They are of no use in our new test system.)
Please help.
Many thanks in anticipation.

Hi Paul,
See SAP Note 694895 - Performance and tables RSMON, RSDONE
Note Language: English Version: 5 Validity: Valid Since 29.11.2005
Summary
Symptom
Tables RSMON* (for example, table RSMONMESS) and tables RS*DONE (for
example, table RSSELDONE) continuously increase in size in the BW system
with each request that is created.
Currently there is no option to reduce these tables.
Do not delete any entries from these tables. If you did, this would have
the following consequences:
When you carry out the next check for the requests for which you have
deleted records from these tables, the check will not run properly.
The status of the relevant requests turns RED in the monitor, and also in
all affected data targets that contain the request.
The affected request and all subsequent requests are no longer visible in
the reporting - all queries on the affected data targets then only display
old data.
Numerous dumps will occur in various situations.
You will not be able to repair the errors caused by the deletion.
More Terms
RSMONMESS; RSSELDONE; Performance; RSMON; RSDONE;
Cause and Prerequisites
This is caused by a program error.
Solution
In the next BW release (BI in SAP NetWeaver 2004s - that is BW 7.0), you
will be able to archive entries from the RSMON* and RS*DONE tables using a
request archiving process that archives the administrative information for
requests.
After archiving, these tables are then considerably reduced in size.
Until then, there is unfortunately no option for reducing the tables.

Will the database size be increased ?

HI All,
I like to ask, will the datafile size be increase, if we put our tablespace in backup mode and forget to put in back in end backup mode.
According to me not, because all the transaction activity will be carried out into redologs and of course, there will be significant increase in redologs. Please correct me, If I am wrong.

The size of datafile itself will not be affected, but as you mentioned, the amount of redo that you generate will increase.

Use OEM to monitor oracle database size

Hello All,
We currently have several database which are currently monitored via OEM however i will appreciate if anyone can tell me how i can monitor the the size of my oracle databases via oem
Thanks

Hi,
I'm not sure of OEM will monitor database size, but many 3rd party tools do.
There are many ways to achieve Oracle table monitoring, and many create specialized extension metadata tables to monitor Oracle table growth. In Oracle 10g you can perform Oracle tables monitoring with the dba_hist_seg_stat tables, specifically the space_used_total column.
On my databases, I create STATSPACK extension tables to track table and overall database growth:
http://www.dba-oracle.com/te_table_monitoring.htm
The full scripts are in my Oracle Press book, Oracle tuning with STATSPACK . . .
http://www.amazon.com/Oracle9i-High-Performance-Tuning-STATSPACK-Burleson/dp/007222360X

Best Trategy to reduce the Database Size

Hi Everyone,
In our Client's Landscape SAP systems have been upgraded to newer versions whereas our client want
one copy of older Production systems (one copy to retain)
1) SAP R/3 4.6 C system (database size of this system is approx 2TB)
2) SAP BW 3.0 (database size of this system is approx 2TB)
Now CLient wants us to reduce the database size via re-organization because Archiving of IDOCs & Links we have already done
Client has recommended for :
1) Oracle Export/Import: Only Oracle DBA can do (ignore this one)
2) Database Reorganization : We have tried Reoragnization via BRtools but found very tedious 9 (ignore this one)
3) SAP Export/Import : Via this way we want to reduce the database size
Can anybody Tell us How much Free space do we require in order at OS level in order to store the Database Export
of Two Databases of size around 4TB & what would be the best strategy of reducing the Dabase size.
Via SAP Export/Import how much approx how much database size will be reduced
Thanks & Regards
Deepak Gosain

Hi,
>Can anybody Tell us How much Free space do we require in order at OS level in order to store the Database Export
>of Two Databases of size around 4TB & what would be the best strategy of reducing the Dabase size.
The only realistic way to know is to do a system copy of the production system on a testbed system and to test the Database Export.
If you really want to decrease the database size you will have to archive a lot more than the IDOC archiving object.

Olivier

Rebuild Database did not reduce the database size

I just completed a rebuild database. The rebuild completed much quicker than anticipated and in the end the did not reduce in size.
This is my first rebuild and since original installation I have deleted a number of masters. From my understanding thumbnails and previews are not deleted when the master is deleted. In order to delete the thumbnails and previews the db must be rebuilt. Is this correct?
The db is over 31.1gb. The rebuild took approx 10 minutes and when completed the db size was still 31.1gb. There was a message during the rebuild that read "Recovering projects". I was expecting to see stats showing previews and thumbnails being generated in the activity window but don't see it. Has the db been rebuilt?
Thanks for any assistance.

Rebuilding the database is for disaster-recovery, not file maintenance. I certainly wouldn't do it unless something was fundamentally broken and the application didn't run.
"rebuilding" the database seems to do the following:
(1) remove the database file completely (not even to the trash, it destroys the database utterly)
(2) run through the plist files and reconstruct a brand-new database from them all
I checked this (on an empty library) using hard-links from the commandline, and step (1) above scared me sufficiently that I'd only rebuild the database as an absolute last resort.
Now, 31GB seems a lot for a database that only took 10 minutes to rebuild - are you sure you're not telling us the size of the library (to find the database size, right-click on the library and select view-package-contents, then open the 'Aperture.aplib' folder and find the size of the 'Library.apdb' file. That's the file you're changing when you 'rebuild database'.)
If you're telling us the size of the entire aperture library instead, then that size will be completely dominated by the master RAW files you've imported. I'd guess your library will be less than 10MB.
My understanding is that previews are deleted (since they're stored as separate files alongside the master image, if you look in the folder hierarchy), but thumbnails aren't. The thumbnails are aggregated together into one-file-per-project (presumably for speed of access), and I'd guess the space is reclaimed for future use, but the file doesn't get any smaller. That's a classic trade-off for speed-of-access, and users like us are normally very keen on things being fast

How can we reduce compares Database size in express edition

Hi,
for client we use SQL server express edition. express edition has limitation of 10GB of database size.
please help me how can we reduce/compares DB size.
Regards,
Manish

Data or page compression feature is not available in express edition so you cannot use this feature to help you.
You might be lucky to reclaim space from shrink operation but eventually data file will grow again. So your best bet is using licensed version.

How to reduce the size of a database ?

Hi,
I would like to know what are the possibilities for reducing the size of a database storage.
I have thought about compressing big indexes and tables.
Have you others ideas ?
thx

thxIt depends. Have you evaluated what takes up the space? Do you have data that can be archived? Do you have high water marks that will never be reached? Do you have sparse data that could have free space removed, just leaving expansion space in new or updateable blocks? Do you have unused indices or tables? What type of systems do you have, OLTP, DW, DSS? Is your data normal? Is your app software enterprise? Are your datatypes correct? Is your storage cheap?
So many possibilities!

I need to reduce the size of several pdf files before transferring them onto a research database. Each file is made up of 100 images (pages of diaries)

I need to reduce the size of several pdf files before transferring them onto a research database. Each file is made up of 100 images (pages of diaries) & is up to 1.36 GB in size. I have tried reducing file size in preview but the images are unreadable. Any ideas?

WHen I want to reduce the file size, I either use "Optimize Scanned PDF", or more often use "Reduce File Size". Both are on the Document menu. The Reduce File Size selection has some limited customization that is used, when selected.

How to reduce the database size based on MS SQL/Oracle?

Hi,

my platform is: NT, MS SQL 2005
NT, Oracle 10.2
Best Regards,

Hi Simon,
In the case of SQL you need to check how many space free you have in your datafiles and the based on that you need to Shrink them using DBCC SHRINKFILE command.
Find a couple of reference docs here,
http://www.intermedia.net/support/kb/default.asp?id=996
http://doc.ddart.net/mssql/sql70/dbcc_21.htm
Also i'm pretty sure that if your check the properties of the datafiles in MSSQL Enterprise Manager you get a "Shrink" option.

How to reduce the database size after deleting huge amount of rows?

Deleting large data would have ultimately put ghost cleanup into action. You would not be able to free space using shrink operation untill it completes. So wait for time and then start shrinking. You should note that shrinking would cause fragmentation and
you would have to rebuild indexes after shrinking is completed

Could you please tell me is there any way to reset the HWM at Datafile level and how we reset the HWM of those tables having Materlized view?

Hello,
I'm not really sure what is the problem here? Everything seems to be OK. From what I have seen ,your database can stand to be resized down quite a bit.
The actual amount it can be resized down depends on the highet HWM for the segments in the datafile, as in:
set line 200col file_name format a90
select file_name,
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) USED_SPACE,
ceil( blocks*&&blksize/1024/1024) SIZE,
ceil( blocks*&&blksize/1024/1024) -
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) ECONOMY --how much of the space can be reclaimed
from dba_data_files a,
( select file_id, max(block_id+blocks-1) hwm -- here we get the max hwm for the datafile from the extents residing within it
from dba_extents
group by file_id ) b
where a.file_id = b.file_id(+)
and ceil( blocks*&&blksize/1024/1024) -
ceil( (nvl(hwm,1)*&&blksize)/1024/1024 ) > 2000
>
You can also do a reorganization of the segment you suspect has a high degree of reclaimable space within its extents (high HWM and low actual space used). You can run segment advisor to help with that.
Hope it helps,

How to reduce the size of the database

Hi
My recent observation on my DB size and the population of it. Apparently the DB is very fragmented and I have actual data upto 800GB but the container size is more 1.1TB.
Could you kindly recommend me what to do in order to reduce the size of the allocated container space?
I appriciate value suggestions and URLs.
