Media Cache vs. Media Cache Database

And why would the "Save media cache files next to original" be of any use??
Within CS4, i'm trying to understand the differences between the two..
If understanding how cache files work, i'm sure many of the users problems would be fixed, and performance improved.
Is there any references or .PDF's to show me how CS4 works with cache files, and how they effect the projects?
This is very important information, and i can't believe I haven't found anything concrete...
Just breadcrumbs of information on the boards here..
Thanx...

I highly recommend you read the 11g New Features Guide. Here is a sample from it:
h4. 1.11.2.9 Query Result Cache
A separate shared memory pool is now used for storing and retrieving
cached results. Query retrieval from the query result cache is faster
than rerunning the query. Frequently executed queries will see
performance improvements when using the query result cache.
The new query result cache enables explicit caching of results in
database memory. Subsequent queries using the cached results will
experience significant performance improvements.

Cleaning Media Cache Database Questions

Does cleaning the Media Cache Database only delete the cache and database links for missing files in the current project? Or does it do it for all of your PPro projects located on your computer except the current project you have open?
How do I delete the cache and database links on my Mac for projects that no longer exist? Apparently I can't see the Library directory to where PPro has my Media Cache pointing to. Can only see it if I go through Admin profile.
Many thanks

Bridge's database CAN be quite large, especially if one has a lot of material on the system, that goes into Bridge. I am always a bit surprised at how large those database files can be, over a year's usage.
As I am using Bridge more on a Project basis, with the original Asset files on my NAS, or elsewhere, I can usually safely purge those, when they grow very large - I no longer need those, when the Projects are completed, and the Copies of my Assets are also Deleted from the system.
Good luck,

Clearing the Media Cache Database

Hi, In a tutorial on using Encore CS6 it says to "clear the media cache database"
Why is this done? ...and if done... does it remove any important files, clips, assets..etc that are in my other projects? Is it safe to do this?
Thanks

PPro and Encore create MANY temporary files, which may be deleted when you are done with the project... your original video clips and project files are in a location of your choosing, not in the cache folders
Some more on locations http://forums.adobe.com/thread/1007934?tstart=0
And, one way to design your project http://forums.adobe.com/thread/919388?tstart=0
I always create my project files on my 2nd hard drive (see below) so the temporary files are also put on that drive
My 3 hard drives for video editing are configured as...
1 - 320Gig Boot for Win7 64bit Pro and ALL program installs (2)
2 - 320Gig data for Win7 paging swap file and video project files
When I create a project on #2 drive, the various work files follow,
so my boot drive is not used for the media cache folders and files
3 - 1Terabyte data for all video files... input & output files (1)
(1) for faster input/output if you have 4 drives
- use drive 3 for all source files
- use drive 4 for all output files
(2) only 60Gig used, for Win7 & CS5 MC & MS Office & other smaller programs
Search Microsoft to find out how to redirect your Windows paging swap file
http://search.microsoft.com/search.aspx?mkt=en-US&setlang=en-US
I do not use RAID... AVCHD is CPU intensive, not drive intensive like uncompressed, so
I have no problems editing without RAID (but, this is for "simple" home videos)

Media Cache Database and running out of disk space

Adobe enthusiast here, still learning about PP CS6:
I was running out of space on my c: drive and under preferences in PP...Media...I found the location was set to my AppData folder\Roaming\Adobe\Common\
This AppData folder had nearly 1/2 of my entire hard drive space used.
I clicked the 'Clean' button and I got back a lot of space.
Can I choose another drive and folder for my Media Cache Database?
Is there going to be a problem since I clicked on the clean button?

Media Cashe Files & Media Chase Database?

I'm running:
CS4 Production Premium
Vista x64
8Gig RAM
Dell T4300 Workstation
DuoCore 2.6Mhz
1T System 7200rpm SATA HD
4 - 7200rpm SATA HDs dedicated to Video Projects (2- 1.5T & 2- 500Gig)
I started a new project Monday, captured 6 hours of video (3 cameras, 2 hours each of a Musical Performance). As I was working yesterday, I noticed when I rendered, the 'render progress bar' would move (showing the progress), then pause for several seconds, move some more, then pause again, as if the renders were being written from RAM onto the HD. "Normally", I see the render bar progress consistently, sometime slower than other times if the clips being rendered have filters, effects, etc., but I've never seen the progress bar simply pause before.
Because I had (a couple weeks ago) changed my Media Cashe Files to "store next to originals when possible", I was thinking this may be the cause. I've changed that back to the default (unchecked the box) but the condition still exist. The "Media Cashe Database" is set to: "user\....\Adobe\Common". As far as I remember, I've never messed with that before. I also noticed the location for the "Scratch Disk" is listed in "user\....\Adobe\After Effects CS4". Why would a PremierePro project have the "Scratch Disk" set under the AfterEffects folder? (I changed this to "Same As Project".
What is the "best" option for the two Project Preference settings for:
1) Media Cashe Files
2) Media Cashe Database
TIA,
jd

No, you'd have to delete them. That's one benefit of storing the media cache files next to the originals, in that you can simply purge the entire directory of files when you're done with it. Splitting them up creates a bit of a file management issue, since Premiere really doesn't have a good way to selectively eliminate generated preview files. The Project Manager works to an extent, but it will still leave the originals behind. So as long as you set things up at the beginning of a project correctly, it'll make finishing and archiving the project a little easier. The good news is that if you delete a cached file that another project needs, it will be recreated automatically. Rendered previews would have to be manually recreated, however.

When group-working from SAN, where is the best place to store Cache Files, the Cache Database, and render files?

I have a small post production house, and we are spinning up into editing our first series. We're all working from a SAN, and sharing projects and sequences via the Media Browser. It's working great so far, but we've been having issues (could be user error) with trying to figure out where best to store the Media Cache database, the cache files, and the preview files so when a project is moved from one machine to another, it doesn't constantly have to re-conform all of the media in the project.
We have a very large master project, as this is a documentary style show, so there are hours and hours of clips.
When I open a project on a new or different machine it has to conform EVERYTHING in the project again.
Where should I store all these conform and cache files so that new people can get started working without having a machine literally be unusable until the conform process finishes?
Thanks!

Hi Jon,
I have a small post production house, and we are spinning up into editing our first series. We're all working from a SAN, and sharing projects and sequences via the Media Browser.
Glad it is working for you. Just to let you know, this workflow is not officially supported so your mileage may vary based on the kind of system you're working with. There are a lot of variations to the quality of these kinds of systems. Some are turn key, some home built - so I think you understand.
It's working great so far, but we've been having issues (could be user error) with trying to figure out where best to store the Media Cache database, the cache files, and the preview files so when a project is moved from one machine to another, it doesn't constantly have to re-conform all of the media in the project.
While it's possible to have the cache files (and the database) in a central location (I only know of one place that pulls that off, and it's a very, very large place), the systems that have this data stored locally are far more reliable. You can work around all the reconfirming by avoiding moving the project data around. You really don't need to move the project around from place to place. Have one computer as the "hub" for inputting data from other workstations. Wouldn't that work?
When I open a project on a new or different machine it has to conform EVERYTHING in the project again.
Can't you just have the master project on one machine and work on shorter sequences of your doc on the other machines? When done, just import to the master machine.
Where should I store all these conform and cache files so that new people can get started working without having a machine literally be unusable until the conform process finishes?
Premiere Pro simply must have those cache files in order to work. Sorry, there's no way around this problem unless you change your workflow.
Thanks,
Kevin

ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode

Hi All,
Need help from the gurus.
Currently we are in state unable to do anything.
Was using a database and all of a sudden it crashed. Tried to mount the database, open it, it failed. Also tried the recover and alter database open, even that failed. Errors are as follows.
Errors in file e:\oracle\product\10.2.0 \admin\devrevdb\bdump\devrevdb_p000_2620.trc:

In my spfile, the administrator has set only two control files and there is no mirroring and hence do not have another control file that will help me boot the db.
Please let me know how I should go about it. I am only a timebeing person trying to carryout a db activity. Any help would be of great help.

Hemant,
thanks for the reply.
I tried the way you suggested and it threw an error.
ORA-01145: offline immediate disallowed unless media recovery enabled
I searched and found that an additional tag of drop needs to be added to the command which you suggested.
ALTER DATABASE DATAFILE '<filename>' OFFLINE DROP.
i don't know what will the drop command have an effect ?
i have copied the data file to another location. Since i don't know much, i just want to be sure of what im doing.
if the above command is successfull, will it drop the datafile or the tablespace and i can no more use it. How can i use the copied datafile.
Thanks,

Is transparent gateway needed to connect to IS Cache database?

Hello,
I have been asked by one of our developers how to create a connection from his Oracle 11.2 database to SQL Server and also InterSystems Cache' databases without having to use Transparent Gateway?
Is this possible, and if so, how can it be done?
(thanks in advance)

Hi,
You say - "I guess it means that Oracle Database Gateway is FREE (per se)" but to make the point again - only the Database Gateway for ODBC (DG4ODBC) is free. The other gateways need a license.
If you run on Windows then many of the Microsoft ODBC drivers are free or included as part of other products so you do not need to pay for them, and also many non-Oracle database providers include an ODCB driver as part of the product, so again you do not need to pay for anything else to use DG4ODBC, for example MySQL.
To interface with a Cache database you can use Dg4ODBC but you need to provide the ODBC driver. There is not a 'dedicated' database gateway for that product. That is why we provide the DG4ODBC which can interface with any non-Oracle database or datastore for which a compatible ODBC driver is available.

can you please help in solving this problem sir....
thanking you,
prakash

THe main issue is this:
TNS:could not resolve the connect identifier specified rc = -1
TimesTen is not able to resolved the TNS name 'XE'. You need to be sure that (a) your TimesTen instance is correctly configured with the correct value for TNS_ADMIN. This should have been specified at install time but if not you can change it by running ttModInstall as the instance administrator. You will need to shutdown the main daemon and re-start it after making this change. Also, all users who will access Timesten need to have the environment variable TNS_ADMIN, set to the right value, present in their environment.

PLZ DON'T SEND ME ANY LINK LIKE TELLING THAT FOLLOW THE INSTRUCTIONS FR THE INSTALLATION BY ORACLE OR SOME WRITER OR SO..

Well, I'm never sure what to write to someone that stuffs up the business of installing Oracle and then tells people what he will or won't accept by way of advice! ESPECIALLY WHEN THEY START SHOUTING BEFORE EVEN GIVING SOMEONE A CHANCE TO REPLY!!
It is in any case very difficult to offer any meaningful advice to someone who thinks that minor details such as his distro and his processor architecture is irrelevant.
The plain fact of the matter is, however, that 32-bit installs of Oracle on practically any distro you care to mention are simply a matter of doing a default OS installation, downloading one shell script and executing it: http://www.dizwell.com/prod/node/1208
Sorry if you don't like that advice, but it's true nonetheless. 64-bit installations can be a bit trickier, that's for sure...
Meanwhile, your ORACLE_SID, ORACLE_BASE and ORACLE_HOME don't appear to be set and your PATH seems to be set incorrectly, so it seems as if not very much of the necessary prerequisites have been carried out correctly. And the specific error message you're receiving seems merely a result of not launching the installer correctly. Try /media/cdrecorder/database/runInstaller, always assuming your installation media is sound, of course: I don't know how you got your Oracle CD ready, but you might take a look at http://www.dizwell.com/prod/node/1207 to make sure you did it right.
(While you're at it, perhaps you'd be kind enough to go edit your original post and break that LS_COLOURS line up, because right now it's causing your post and any replies to be fitted across an incredibly wide screen, necessitating a lot of horizontal scrolling).

Open Window Media Player Database using Sql Server?

I would like to be able to list the file paths stored in that database.
I don't suppose that I could use SQL Server to do that, could I?
Is there any other way at all to make such a list?
Even a suggestion to try something would be appreciated.

SUP - 2 questions about the CDB (cache database)

Hi,
I have 2 questions about the cache database and the cache groups:
1 - How does the "On demand" cache group policy exactly works? I know that online cache group is without storing any data on the CDB making direct requests to de backend from the device, the DCN is based on updating from the backend, the scheduled is based on a time period, but I don't understand how the "on demand" exactly works, and why it has a time period too.
2 - Is it possible to query the cache database table to check the data that SUP has stored? How can I do this?
Thank you!

I posted a similar question in SUP Apps project not too long ago and Paul Horan provided this useful reply:
Create a "Sybase ASA v12.x for Unwired Server" connection profile in the Enterprise Explorer. I named mine CDB.
: Host = localhost (or whatever the machine name is)
: Port = 5200
: Database name = "default"
: User Name = "dba"
: Password = "sql"
Obviously, change the userid/password to match, if you changed them during install time.
Connect, and you'll see the "default" database displayed.
Navigate down through the Tables folder, and the first subfolder is labeled something like [#should_delete_sk ...] Start there.
You'll see a bunch of tables with the naming convention "D1" + package name + package version + MBO name. These are the cache tables for the MBOs.

How do you rebuild the Cache database?

What are the steps to rebuild the Cache database? Thanks!

The right answer is to log a case with Cisco support to get official steps.
What we do here (an Oracle DB):
- bring down CM
- make an export of TES schema (optional)
- run the clearcache.sql script (in the ../cache/tes6.0.0.0/cachesql.zip) to drop schema objects.
- verify that sql ran correctly and scheme is indeed empty
- restart the CM - in our case it takes 2 - 2.5 hrs for cache to be rebuilt (the secondary sync completed to show up)

Cache database results within any of your software applications?

Have you had to cache database results within any of your software applications? What are the advantages and pitfalls developers should be aware of when caching database results.
plz reply....
........thnks.

We have cached the database results in client side cache (partially in arrays and in files on OS as well). But this caching is restricted to purely STATIC data (which undergoes no change under any circumstances).
Our application relies a lot on static data and we managed to reduce 10% of network bandwidth with this implementation.
We tried using client side cache for not-so-static data but had lot of issues related to refresh of the same so we reverted that change.
On a side note, this does remind me of the client result cache available in Oracle 11g.

CACHED Database....urgent

Hi all,
when we delete the record from the table, size of the file is not reduced. but when add the record to the table, the size is increasing. Can anyone suggest why size of the file is not reducing when delete record from the table.
Best Regards,
Muthu.

this does not appear to have anything to do with java.
however... it looks like cached loads the table into memory. then when inserrts happen to the table in memory there is a forced write to the disk but when deletes happen they are not neccessarily written out to disk right away. so the answer for your "problem" is simple you either have to live with slower performance from uncached tables or you have to live with your table gowing problem.
i would suggest you discover the name of your database vendor... like is it sybase or oracle or whatever and go their site and find your answer. again this problem is related to your database and not java as shown by the fact that your are using a CACHED keyword in your SQL create statement.
