Is their a maximum database size for DB2?

Hello,
we got a request from our business to install a new bw system on DB2 V8.2/V9 with an estimated end size of 100 Terabyte. I know, we have to ask our hardware partner, for sizing and this will include, partitioning,... But the first question from my side is "Is their a maximum size for a db2 database installed on aix?" Has anybody experience with such a huge database. At the moment our biggest database is about 1,4 Terabyte.
Regards,
Alexander

Hi Alexander,
A 100TB size sounds ambitious ... any thoughts to when the system will have that size ? It will also be interesting to understand if it's a OLTP or OLAP system.
There is a "theoritical" technical limit on the total size of a database, but that's really beyond reason. Here is how it goes:
A regular tablespace can be no larger than 512GB per DPF partition. A large tablespace can be no larger than 16TB per DPF partition. You can have 32767 tablespaces in a database. You can have up to 999 DPF partitions in a partitioned database server.
Coming from that the current technical limit is:
Non-partitioned database server: 16TB x 32767 tablespaces
Partitioned database server: 16TB x 32767 tablespaces x 999 partitions.
Regards,
Torsten

Maximum Database size in exchange 2007

Hi Team,<o:p></o:p>
What is the maximum database size we can have in Exchange server 2007 SP3 RU8 standalone server.<o:p></o:p>
In our environment we have 1800 users hosted on the
exchange 2007 server with DB size(EDB file) of 1.61TB. What is the maximum size it can grow upto. Any response appreciated.
Thanks<o:p></o:p>
Srini<o:p></o:p>

Amit just beat me to posting Harold Wong's article! :-) Since you're currently on 1.61TB the artificial limit has already been adjust via the registry setting mentioned (the article mentioned 50GB though I've seen others mention 250GB). So the maximum limit
is 16TB, but whoever adjusted things to allow your current size may have set the artificial limit as something smaller, so you'd want to check the registry to see what it has been set to in your case.
I'd also echo the comments about database size. Depending on how you handle backups then they may also play a part. Since most backups work on the basis of backing up / restoring the entire database (obviously backing up changes rather than the whole thing
each time), then the event of you needing to restore it's much easier if you have smaller databases to deal with. Splitting your mailboxes across multiple stores will help minimise the time required before you can get some users online again in the case of
a total failure. Also, if you split your mailboxes across 5 databases and then have a problem (for instance corruption) on one of them, then only around 1/5 of your users are effected rather than all of them.

Maximum database size Exchange 2013 Standard

Hi,
Does anybody is aware of database size limitation for Exchange 2013 Standard. I remember in older version there was a registry tweak to increase database limits.
Thank you

Hi,
This is the official answer :
Supported: Approximately 16 terabytes.
Best practice:
2 terabytes or less.
Provision for 120 percent of calculated maximum database size.

What is an idea of maximum file size for a film in Captivate?

Hi there,
I'm creating an elearning course in Captivate 7, and it is being published as HTML5. This means the films I've imported are being converted to MP4s, and they are around 10-20mb in size once they've converted. They seem very slow to load on some computers - do you think the file size is too big? Or could it be another issue? Does anyone have a recommendation for maximum file size for films? They are 572 x 322px and around 1-2 mins in length.
Thanks in advance

Probably better guidelines that dictates 'size' of a vi are:
typically no more than 1 video screen in size
is it legible
and is it's function and operation clear.
I have seen examples of '1 vi does it all' that were many screens wide and tall, totally a flustercuck, and nearly 1 MB in size.
Globals and local variables (except for LV2 style) are typcially shunned for they can create a host of problems (race conditions, indeterminant data).
Use connector pane to wire controls and indicators to. Then use wires between vi's to transfer data. I tend to use clusters to hold shared data.

Maximum font size for auto-sized form text

You need to let the user select a maximum font size for automatically sized text. If most of your fields are set at 10pt type, but you have one field for which you want the text to resize automatically, it looks stupid if that cell contains a small amount of text that’s set at 16pt or whatever. If you could set the maximum font size to 10pt for that field, then the text would be consistent with the text in the other fields unless there is so much text that it needs to scale down.

Can anyone please advise?
Cheers

Maximum file size for export into MP4?

Hello,
I am not able to export 2 hour HD video into standard MP4 file. It seems that reaching 100% export algorithm gets into loop. I was waiting for hours and still had seen progress at exactly 100% with final file size on hard disk to be 0 bytes. I am using CS5 on MAC OS X. I had to split my timeline to 2 parts and to export them separately (which is embarrasing). Is there something like maximum file size for export? I guess that 2h video would have about 25-35GB.
Thank you
jiri

You are right.
So I am running AP Pro 5.0.4, Adobe Media Encoder 5.0.1.0 (64bit). Operating system Mac OS X ver 10.7.3. All applications are up to date.
MacBook Pro Intel i5 2.53GB, 8GB RAM, nVidia GT 330M 256 MB, 500GB HDD
Video is 1920x1080 (AVCHD) 25fps in a .MTS container (major part of timeline), 1280x720 30fps in .MOV container (2mins), Still images 4000x3000 in .JPG
No error message is generated during export - everything finishes without any problem...just file created has 0 byte size (as described above).
This is my largest video project (1h 54min) I dont have any other problem with other projects.
I dont run any other special software, at the moment of export all usual applications are closed so that MacBook "power" can go to Media Encoder. No codecs installed, using VLC Player or Quick Time.
Attached please find printscreen from Export settings (AP Pro). Writing this ppost I tried to export only the first 4mins from timeline where all kind of media is used...and it was OK.
As a next step I will try to export (same settings) 1h 30mins as I still believe problem comes with length of video exported.
Let me know your opinion

Maximum file size for importing into Premiere Pro CS6

Hi,
I'm considering recording raw video, no compression at 720p, 30 fps for 20-30 min. This woudl result in a file that is close to 80 Gbytes. I'm wondering what the maximum file size for importing into premiere Pro is and if I need to split this file up into smaller pieces. Any recommendations on how I may deal with uncompressed raw video that is pretty long in length?
Thanks,
Serena

There is bound to be some limit somewhere in the program, but you should be well below that. The biggest issue might be whether your computer is up to the task of handling it. If you will post your computer specs., someone will give you comments on that aspect.
Good luck,

where is this limitation coming from. How to set the heap size to 6g.
Thanks for your time
Meena

You need to use the -d64 switch to request the 64-bit JVM. E.g.,$ java -showversion -Xmx6g HelloWorld
Invalid maximum heap size: -Xmx6g
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
$ java -showversion -d64 -Xmx6g HelloWorld
java version "1.6.0_07"

Maximum HD size for MDD G4?

Hi there
I had a real pain in the proverbial when trying to do a clean install of Panther (or Tiger) on a 1Ghz G4 on a new 200 Gb HD. There were instablilities, Hands on shout down/restarts, etc, before running any updates or 3rd party apps.
Is there a maximum HD size for these Macs? It came with a 80Gb HD.
Thanks for any help...

Some RAM that worked under prior versions of OS X has been known to fail. Tiger makes much more use of all available RAM for cache is part of the reason. Memtest would give it a good workout overnight.
MDDs support Cable Select, it depends in part on the IDE cable itself. In fact, you could use it on older Macs and controllers most of the time.
Never apply an update without first doing a backup and some disk repair and maintenance. Even flushing the cache folders with something like Applejack. Never use your Mac while an update is taking place. Reboot prior to applying an update, might want to use Safe Boot Mode. And use the standalone updates, and the combo update if possible. On some occasions it was necessary to reapply the combo update.
With Tiger, I found that while it was possible to update, a full erase and install resulted in a better OS. So backup.
If you keep your home directory or backup on another drive, so much the easier and better.

Maximum package size for data packages was exceeded and Process terminated

Hello Guru,
When i am execute the process chain i got this message Maximum package size for data packages was exceeded and Process terminated,any body help to me in this case how can i proceed.
Thanks & Regards,
Suresh.

Hi,
When the load is not getiing processed due to huge volume of data, or more number of records per data packet, Please try the below option.
1) Reduce the IDOC size to 8000 and number of data packets per IDOC as 10. This can be done in info package settings.
2) Run the load only to PSA.
3) Once the load is succesfull , then push the data to targets.
In this way you can overcome this issue.
You can also try RSCUSTV* where * is an integer to change data load settings.
Change Datapackage size for extraction, use Transaction RSCUSTV6.
Change Datapackage size when upload from an R/3 system, set this value in R/3 Customizing (SBIW -> General settings -> Control parameters for data transfer).
IN R/3, T-Code SBIW --> Genaral settings --> Maintain Control Parameters for Data Transfer (source system specific)
Hope this helps.
Thanks,

"Maximum package size for data packages was exceded".

Hi,
We are getting the below error.
"Maximum package size for data packages was exceded".
In our scenario we are loading the data product key wise (which is a semantic key as well) to the DSO thro’ a start routine.
The logic in the start routine is such a way that it calculates the unique product counts , product key wise. Hence we are trying to
group the product key thro’ semantic groups.
Ex: In this example the product counts should be A = 1,B=2 ,C = 1
Product Key
Products
A
1000100
B
2000100
C
3000100
B
2000300
C
3000100
For some product keys the data is so huge that we could not load the data & we are getting the error.
Please suggest any alternate way to handle this thro’ code or introducing any other flow.
Regards,
Barla

HI
we can solve the issue by opening the system setting of data packer size
like below we have create 2 programs, 1 for open the system settings,2 for
close the settings .
1 start program
data: z_roidocprms like table of
roidocprms.
data: wa like line of z_roidocprms.
wa-slogsys = 'system_client' . wa-maxsize = '50000'. wa-statfrqu = '10'.
wa-maxprocs = '6'. wa-maxlines = '50000'.
insert wa into table z_roidocprms.
Modify roidocprms from table z_roidocprms .
2 close program
data: z_roidocprms like table of roidocprms.
data: wa like line of z_roidocprms.
wa-slogsys = 'syetm_client' . wa-maxsize = '50000'. wa-statfrqu = '10'.
wa-maxprocs = '6'. wa-maxlines = '50000'.
insert wa into table z_roidocprms.
modify roidocprms from table z_roidocprms .
data load infopakage settings we have to maintain like
below
we have create the process chain like as below
1 start progarm
data load infopakage
2 close program.
This might fix the problem.

Polu.

Maximum message size for internal users

Hi,
Is it possible to configure a maximum message size for internal users and also create exceptions?
The templates available in Transport Rules only allow for "when size of any attachment is greater or equal". This is not ideal as users can add 50 X 1MB attachaments to an email etc.
Configuring Transport settings or Receive Connectors do not allow for exceptions.
Thank you.

Hi Prakash,
Thanks for the link to the thread. The AD site link configuration is valid but does not account for the required exceptions. E.g User A can send unlimited size message to User B but not to User C.
The thread also mentions the Transport Rule configuration stated in my original post but that configuration has one major flaw. Users can circumvent the control by splitting attachments.
