Monitoring Tablespaces for critical Total Size

Hi,
I know that from RZ20 and dbacockpit you can monitor the Tablespace Storage. These alerts are for actual physical storage. My question; is there a monitor/report that can warn you of tablespaces that are reaching their limit.
E.G:
In DB2 V8, the max tablespace size for a 16kb page size is 256 GB (Regular Data). Is there a way of monitoring a tablespace, to warn you that it is nearing this limit.
Kind Regards,

BRSPACE create new tablespace for compressed table

Dear expert,
I'm plannng to create new tablespace PSAPCOMP for compressed table by brspace.
the current total size of the tables that i want to compression is 1T.
Now i have 2 question about the brspace script
1.How big size should the PSAPCOMP be , let's say 500G?
2. i'm confused about the datafile_dir value i should put (please refer to the attachment for current datafile_dir design)
Could you help to correct/improve the scritpts as following?
scriptA : brspace -f tscreate -t PSAPCOMP -s 5120 -a yes -i 100 -m 15360 -f sapdata4 -l 2 --> assign to sapdata4
repeat scriptB for 20 times
scriptB : brspace -f tsextend -t PSAPCOMP -s 5120 -a yes -i 100 -m 15360 -f sapdata4 -l 2 -f1 4 -f2 4 -f3 4 -f4 4 -f5 4 --> extend 25G in one run
Qestion: is it OK to assign the PSAPCOMP only to "sapdata4"? or i should specify "-f sapdata1 sapdata2 sapdata3 sapdata4" so the table data can distribute among different sapdata_dir?
Thank you!

hi Kate,
some of the questions depend on the "customer" decision.
is it OK to assign the PSAPCOMP only to "sapdata4"?
how much space is available? what kind of storage do they have? is totally stripped or not? is there "free" space on the other filesystems?
1.How big size should the PSAPCOMP be , let's say 500G?
as I explained to you already, it is expected that applying all compressions you can save 1/2 of the space but you have to test this as it depends on the content of the tables and selectivity of the indexes. Use the oracle package to simulate the savings for the tables you are going to compress.
do you want the scripts interactive (option -c) or not?
The SAP Database Guide: Oracle has all possible options so you only have to check them
brspace -f tscreate -t PSAPCOMP -s 5120 -a yes -i 100 -m 15360 -f sapdata4 -l 2 --> assign to sapdata4
if you want to create a 500 GB, why you limit the maximum size to 15360?

How to find total size of selected items in library

My library contains much more than my 2GB Nano can hold. I frequently change the content of the Nano with songs and books. How can I keep track of the total size of items I'm selecting for the next Nano update to speed my update? Presently I can only guess what to unselect if the selections are of greater size than my Nano will hold.

There is no direct way to accumulate total file size when selecting a subset of songs within the Library or a Playlist.
The only way you can manage this is to create an empty Playlist that you can drag songs into. It will accumulate the total size of the songs as you deposit them into it (as described by StarDeb above).
If you get to a size greater than the nano will hold, then remove one or more songs from that Playlist.
There is no 'running-total' of only the selected items like Windows Explorer does. Sorry.

How do I calculate the total size of selected folders?

Hello
My question is:
How do I calculate the total size of selected folders?
Thank you

It does show the aggregate size.
Command-Option-I opens the Inspector window. (Or open the File menu and hold the Option key. Get Info turns into Show Inspector.) The Inspector is similar to the Get Info window but it shows aggregate info for multiple selections. It is also dynamic — if you change the selection while the Inspector is open, the info changes to reflect the current selection.

How to find total size of RMAN backup files?

Hi there
env: Oracle 10gR2, RHEL 64bit
My client has a production database where rman backups are taken: Level-0 backup every Sunday and Level-1 Monday thru Saturday.
I have very limited access to this production database because it is being managed by third party and they won't provide me my required info (not sure why). I do not have access to their rman repository. To connect to the database I have to login to an intermediate server and then login to the database server. I have no access to Enterprise Manager. So in short, my access is limited. I want to gather the information on total size of rman backup files - both for a Level-0 and Level-1 backups separately. I understand that this info can be retrieved from rman repository. Are there any data dictionary views/tables where I may get this info?
Best regards

Monitor Recommendations for Use with Captivate

Anyone have any monitor recommendations for use with Captivate? Size and resolution?

The formal adobe recommendation is as posted 1024x768 is fine.
But, monitors are not that expensive, so for productivity and better work environment I recommend at least one wide screen 22" with resolution 1600X1200 or more and that supports 1080 for video.
You need the wide screen ( or two monitors) so you can work with all the tools in one view.

Imp-00020 long column too large for column buffer size (22)

Hi friends,
I have exported (through Conventional path) a complete schema from Oracle 7 (Sco unix patform).
Then transferred the export file to a laptop(window platform) from unix server.
And tried to import this file into Oracle10.2. on windows XP.
(Database Configuration of Oracle 10g is
User tablespace 2 GB
Temp tablespace 30 Mb
The rollback segment of 15 mb each
undo tablespace of 200 MB
SGA 160MB
PAGA 16MB)
All the tables imported success fully except 3 tables which are having AROUND 1 million rows each.
The error message comes during import are as following for these 3 tables
imp-00020 long column too large for column buffer size (22)
imp-00020 long column too large for column buffer size(7)
The main point here is in all the 3 tables there is no long column/timestamp column (only varchar/number columns are there).
For solving the problem I tried following options
1.Incresed the buffer size upto 20480000/30720000.
2.Commit=Y Indexes=N (in this case does not import complete tables).
3.first export table structures only and then Data.
4.Created table manually and tried to import the tables.
but all efforts got failed.
still getting the same errors.
Can some one help me on this issue ?
I will be grateful to all of you.

Thanks, but this note is for older releases, 7.3 to 8.0...
In my case both export and import were made on a 11.2 database.
I didn't use datapump because we use the same processes for different releases of Oracle, some of them do not comtemplate datapump. By the way, shouldn't EXP / IMP work anyway?

Monitor recommendations for PS/CS5.5 print work

Hopefully this won't be retreading old ground too much, but I'm looking for monitor recommendations for using with CS5.5 for print work in Photoshop and InDesign mainly on a new Mac Mini. I've got a Spyder 3 for calibration already so that side of things is covered - the Apple Thunderbolt display is a bit of range financially, plus I'm not sure about the glossy screen myself, ideally I'd be looking to spend no more than £500 and size wise about 24" would be the ideal size due to the amount of deskspace available to me. TIA for any/all help/recommendations!

For starters look heere:
http://www.tftcentral.co.uk/
The degree of perfection is dependent on your final needs. A studio doing catalog work is going to need a monitor all the way up to top providers like Eizo. for my needs where I output to an Epson 3800 and bigger, I find the dell u2412 to be ideal, and at your price category, maybe 2 will fit the budget.
The 2412 does not cover the full Adobe RGB gamut, but it does cover sRGB IEC 61966-2-1:1999, the current preference for online color. I use it because correcting the monitor to match the print for b&w is paramount, and the best monitors for this use LED backlight. The u2412 is admirable for this especially at it's price point.
I also use a 2nd monitor but it is a smaller 4:3 aspect ratio. It's use is strictly for tools and such.
The 2412 is a 16:10 aspect ratio and is far better, imo, for graphics work. Also (and maybe especially!) it is very close to the golden mean ratio giving it a wonderful presentation format. Check it out where you see 16:9 and 16:10 side by side.
When I am working closely with adjustment layers I have enough room on my screen to pull over the specific palette next to the image while tweaking, a big help without losing the ability to fill the screen later if you wish. Simply move the palette back to it's home on the other screen.
Good Luck!

Do I need multiple DATA/INDX tablespaces for a DB on a SAN?

Is there any advantage to creating multiple DATA and INDEX tablespaces for databases that are on a SAN? Database size is probably going to be around 1TB per year.
Our databases are normally smaller and perform well with a single DATA tablespace and single INDEX tablespace. I would like to see if we need to use a different approach with a larger db and a SAN in place.
Thanks

Recommendations for reducing output size

Hello,
My RoboHelp 10 merged project has three SSL outputs: Windows, Linux and Mac versions. Each image in the project therefore has three versions. I have 194 topics, not a huge project, IMO. The generated output for the Windows version is 30.8 MB, which is 1,008 files, about 500 of which are image files, 27 folders. Theoretically, this means that all three versions when published have a total size on disk in the area of 90+ MB. My issue is that I work on the project locally, generate locally, publish to a remote source controlled location and then the network guys copy the published output to a web server. They want me to find out if I can reduce the size of the project so it takes as little time as possible for them to copy it. The copy is the slowest part of the whole thing, including my publish.
One thing I noticed after the last time I published is that every so often, RoboHelp seems to publish extraneous files/folders to the output that should not be there, as in when compared to a local generated version, they are not in the generated version (which clears the output folder each time). When I cleaned up those extra files after our last publish, the size on disk reduced from 45MB to 31MB. Should I just be watching out for the "extra" unwanted/unnecessary folders and deleting them or is there more I can do within my RoboHelp project to reduce the published size?
I've been using RoboHelp since RH8 but just jumped right into it without any training or help, apart from what I've received here (thank you all!) so although my projects look good and perform well, any help would be appreciated! At this point, it is taking so long that the network guys want me to look into switching to another tool that one of them knows. I've invested a lot of time and effort into RH, not really interested in another learning curve.
Thanks!
Helen

Hello again
Hmmm, well, after reading your reply, I'm thinking that you shouldn't get TOO excited just yet. We need to clarify some things.
For starters, you are saying you have different screen captures that you use for each of the outputs? If so, it would seem that maybe you DO actually need the different outputs. But before we can assume that to be true, we need to know more about the actual information being delivered.
For example, what does each of the screen captures show?
What I was thinking may have been overlooked with RoboHelp was that maybe you simply needed to present the SAME information to folks, but they might be using a Windows browser to view it, or a Linux browser to view it or a Mac browser to view it. And if that's the case, there isn't a need for specific images to each operating system.
Cheers... Rick

Dropping tablespace for a partitionned table

Hi all,
I have a table partitionned and I want to drop the tablespace for a specific partition. So what happen in the table if I drop one tablespace with a commande drop tablespace tbs including contents and datafiles;
Does the index unusable in this table?

No, you can not drop a tablespace which contains tables whose partitions are not completely contained in this tablespace.

Method_opt = 'FOR ALL COLUMNS SIZE REPEAT'

Hi all Gurus,
We have a script to take statitics (see below), it runs every day and All the tables has de "MONITORING" option in a 9.2.0.5 database.
My question is concern to "method_opt =>'FOR ALL COLUMNS SIZE REPEAT',OPTIONS=>'GATHER EMPTY',estimate_percent =>5);
So, for a new table with columnns and indexes (with "monitoring" option), will it create statistics or histograms statistics when the script run for the first time on the table??? and then, will continue with/without histograms???
begin
DBMS_STATS.FLUSH_DATABASE_MONITORING_INFO();
DBMS_STATS.GATHER_DATABASE_STATS(DEGREE=>4,GRANULARITY=>'ALL',CASCADE=>TRUE,method_opt =>'FOR ALL COLUMNS SIZE REPEAT',OPTIONS=>'GATHER EMPTY',estimate_percent =>5);
DBMS_STATS.GATHER_DATABASE_STATS(estimate_percent =>5,OPTIONS=>'GATHER STALE',method_opt =>'FOR ALL COLUMNS SIZE REPEAT',degree => 4, cascade=>true,STATTAB=>'TABLA_ESTADISTICAS',STATID=>to_char(sysdate,'yymmdd'),STATOWN=>'OPER');
end;
Regards,

I have taken following explanation from documentation:
{code}
METHOD_OPT - The value controls column statistics collection and histogram creation. It accepts either of the following options, or both in combination:
FOR ALL [INDEXED | HIDDEN] COLUMNS [size_clause]
FOR COLUMNS [size clause] column|attribute [size_clause] [,column|attribute [size_clause]...]
size_clause is defined as size_clause := SIZE {integer | REPEAT | AUTO | SKEWONLY}
column is defined as column := column_name | (extension)
- integer : Number of histogram buckets. Must be in the range [1,254].
- REPEAT : Collects histograms only on the columns that already have histograms.
- AUTO : Oracle determines the columns to collect histograms based on data distribution and the workload of the columns.
- SKEWONLY : Oracle determines the columns to collect histograms based on the data distribution of the columns.
- column_name : name of a column
- extension : can be either a column group in the format of (column_name, colume_name [, ...]) or an expression
The default is FOR ALL COLUMNS SIZE AUTO.
{code}
GATHER EMPTY: Gathers statistics on objects which currently have no statistics. Return a list of objects found to have no statistics.

Possible to increase the total size of a software raid set?

Hi,
I need to increase the size of a software raid set which is internally in one of the Xserves - originally it had 2x 400G drives.
I've swapped drives into the raid so they are both now 500G drives.
diskutil info drive XX (ie raid set) shows that the raid is still a 400G raid volume as expected.
Question is - can I grow the Raid Total Size to use all the capacity of the member volumes?
I guess the alternative is to remove the drives from the raid, enable raid on one of them and then add the other drive as a member... but this would mean I would have to take the raid offline.
The raid sets are not my system disks.
Any clues?
TIA

Thanks for your help.
I rebuilt the array using enableRaid. Worked fine with Raid Volume offline for approx 5 minutes - although I had to degrade the array (and go bare with no mirror) twice in the process.
In case anyone is interested, this is what the process was:
1 Swap into Raid array larger drive (say, disk 2) and let array rebuild
2 Disable file services.
3 removefromraid disk 2 (leave it mounted).
4 Unmount the raid set and eject drives (say, disk 1) Remove drive - it's the only original backup.
5 enableRaid on disk 2
Providing enableRaid is ok -
6 Insert a fresh larger size drive in the place of the removed drive (disk 1)
7 Unmount new drive and addToRaid
8 (Rebuild array). Providing rebuilding ok -
9 Start file services again.
Data, permissions & ACLs were all intact. So now users can fill the rest of the raid up with more MP3s this week <sigh>
Maybe not the best approach but it worked well for me.
