Moving or Purging CameraRaw Cache

I was trying to recover some disk space on my C: drive when I noticed that AppData/Local/Adobe/CameraRaw/Cache was quite large. Can I purge this cache without ill effect? I would prefer to move all AppData to my D: drive which is huge.

Never mind I found the option. It's in Adobe Bridge under Camera Raw Preferences.

Every few minutes Adobe Bridge CC asks me to purge my cache. It is also running really slowly since I just upgraded to Yosemite.

Adobe Bridge is barely working after my recent upgrade to Yosemite (my computer is an imac that is less than one year old, and is working perfectly in non-Adobe programs). It never ever acted up for me, not even once, before. I use it frequently as I am a graphic designer. Previous to Yosemite I had NEVER gotten the purge cache message, and it never took longer than a few seconds to open folders with large amounts of raw photos. Now it has seriously effected my workflow, and I am considering just giving up on cc and reverting to cs5 which I still have on disk. I'm not going to pay the monthly fee if I can't use Bridge properly.
It frequently asks me to purge my cache, and also takes over 2 minutes to load a folder. I have the cache set to 500,000, and have tried all of the recommended settings and the problem persists. I just uninstalled and reinstalled bridge cc, and the first thing that popped up when I opened Bridge freshly after being reinstalled.... Was an message to purge my cache. This is really unexpected. Do you know what is going on??
Also, after Yosemite, Photoshop opens about every third photo as a mosaic of chopped up image parts and bright pink pixelated squares, then locks up so I have to quit out of it and reload photoshop.

I said that I had got back my Bridge today. It lasted 5 hours before it again crashed for the same reason with the cache problem. So it was only a temporary solution. I have maximum capacity in my Bridge cache. Every time I press the OK button after getting the message " Bridge encountered a problem and is unable to read the cache. Please try purging the central cache in the Cache Preferences to correct the situation", Bridge freezes.
Any other thoughts to remedy this please.

Why i am always ask to purge my cache in adobe bridge?

I have gone to the Bridge preferences and purged my cache several times and that has not done anything to rectify the situation.
You still haven't provided much information (what computer, how much RAM, how much free space left etc etc.)
But in general, the central cache sometimes get corrupted, purging it in prefs is not always the solution, you might try it manual yourself. Quit Bridge and go to your user library (by default hidden, use Finder, menu Go with option to reveal) and inhere find the folder Caches / Adobe/ Bridge CC. In this folder are two files, a plug in and a folder called Cache. Drag both files outside the library, preferable trash, and restart Bridge to create both earlier deleted files again as new, fresh but empty files. Take a bit of time to recache your folder and try if this solved the problem.

Dialog box says-"Bridge encountered a problem and is unable to read the cache. ... purge central cache" For one, I can't find the central cache and two, I've purged the cache in bridge. Shouldn't that help.

Our Bridge has been acting very strange. It keeps giving a dialog box of "Bridge encountered a problem and is unable to read the cache. ... purge central cache" For one, I can't find the central cache and two, I've purged the cache in bridge. Shouldn't that help? There's just all kinds of weird stuff going on. I suppose it does have something to do with the central cache, so maybe someone can tell me where to find it.
When I use the burn/dodge tool sometimes it drags and staggers and takes forever to complete whatever I'm burning/dodging. When I try to delete an image from the dock, it won't disappear but it won't display either.
Any help would be appreciated.

The Central Cache is the Bridge Cache.
It's referred as the Central Cache to differentiate it from the individual folder's cache or even the individual image cache.

Lightroom 1.3 creates CameraRaw Cache

I import raw files to an external hard drive on a Win XP system. After installing 1.3, I have a new folder C:\Documents and Settings\my name\Local Settings\Application Data\Adobe\CameraRaw\Cache. A Cache ###.dat file about the same size as the original raw file is created when I open the picture. I use PSE 4.0 to edit so I do not see a need for the CameraRaw file. How can I turn this off? It was not part of v1.2.
Thanks, Richard

Hi Thomas, I measure the timings with the Process Monitor under vista. It shows all IO done by a program. I have a quad core 3.7 ghz machine, with brand new 750GB hd's in raid1 mode, that do about 75MB/s continuous writing. The catalog and images are on a seperate 2TB raid0 volume that does 115MB/s continuous writing.
I just started a preview generation. I use 2048, high quality (because im on the road a lot, and would like somewhat ok images with me).
Here is the first mention in the log of this image, COR_20071003_25547.NEF:
i 1784404 10:53:14.1068606 PM lightroom.exe 4644 QueryDirectory E:\Images\Originals\Cor\Underwater\Solomons\Solomons September 2007\20071003\COR_20071003_25547.NEF SUCCESS Filter: COR_20071003_25547.NEF, 1: COR_20071003_25547.NEF
It reads the 20MB raw file, which takes 0.3 seconds
1785808 10:53:14.4110567 PM lightroom.exe 4644 ReadFile E:\Images\Originals\Cor\Underwater\Solomons\Solomons September 2007\20071003\COR_20071003_25547.NEF SUCCESS Offset: 19,750,912, Length: 1,816, Priority: Normal
Next it fires off a few threads, which take about 0.05 seconds to finish. No idea what these threads do, they seem to take almost no processor time.
Now it starts reading the CameraRaw Cache index file:
1785890 10:53:14.4728629 PM lightroom.exe 4644 QueryOpen C:\Users\cor\AppData\Local\Adobe\CameraRaw\Cache\Index.dat
It starts another set of threads, which also take 0.05 seconds to finish.
Now it has figured out the cache file doesnt exist, and it starts writing it, we're only a mere 0.4 seconds into the process:
1785935 10:53:14.5149033 PM lightroom.exe 4644 CreateFile C:\Users\cor\AppData\Local\Adobe\CameraRaw\Cache\Cache0000013254.dat SUCCESS Desired Access: Generic Read/Write, Disposition: OpenIf, Options: Synchronous IO Non-Alert, Non-Directory File, Random Access, Attributes: N, ShareMode: None, AllocationSize: 0, OpenResult: Created
The cache file is 17MB, and finishes 4.5 seconds later.
1795111 10:53:18.9960440 PM lightroom.exe 4644 CloseFile C:\Users\cor\AppData\Local\Adobe\CameraRaw\Cache\Cache0000013254.dat SUCCESS
Somewhere in the middle of this the actual preview is being written, I guess these things happen in seperate threads:
1793108 10:53:17.6010975 PM lightroom.exe 4644 CreateFile E:\Images\Catalogs\Lightroom_Cor\lightroom_cor\lightroom_cor Previews.lrdata\8\8921\89210BFF-9147-4A7E-819F-CAABEEB30CC7-8e5855ce63af82e5b518514a2227b a68-97.lr-preview.noindex SUCCESS Desired Access: Generic Write, Read Attributes, Disposition: OverwriteIf, Options: Synchronous IO Non-Alert, Non-Directory File, Attributes: N, ShareMode: Read, Write, AllocationSize: 0, OpenResult: Created
1793170 10:53:17.6234413 PM lightroom.exe 4644 QueryOpen E:\Images\Catalogs\Lightroom_Cor\lightroom_cor\lightroom_cor Previews.lrdata\8\8921\89210BFF-9147-4A7E-819F-CAABEEB30CC7-8e5855ce63af82e5b518514a2227b a68-97.lr-preview.noindex SUCCESS CreationTime: 11/23/2007 10:53:17 PM, LastAccessTime: 11/23/2007 10:53:17 PM, LastWriteTime: 11/23/2007 10:53:17 PM, ChangeTime: 11/23/2007 10:53:17 PM, AllocationSize: 1,155,072, EndOfFile: 1,153,664, FileAttributes: A
This takes a whopping 0.02 seconds.
And we're on to the next image:
1795837 10:53:19.2355255 PM lightroom.exe 4644 QueryDirectory E:\Images\Originals\Cor\Underwater\Solomons\Solomons September 2007\20071003\COR_20071003_25548.NEF SUCCESS Filter: COR_20071003_25548.NEF, 1: COR_20071003_25548.NEF
So, let me put the timings close together:
10:53:14.1068606 image read
10:53:14.4110567 done reading
10:53:14.4728629 read camera raw index
10:53:14.5149033 start writing camera raw cache file
10:53:18.9960440 end writing camera raw cache file
10:53:19.2355255 next image
I dont know what LR does internally, so this could be giving a totally wrong idea of whats happening. If the writing of the image is done as a stream while LR is calculating the final image, and not merely writing an internal buffer, then a huge part of that 4.5 seconds would also be used if it werent writing it. Only the LR devs can shed light on that. All I know is, if it isnt writing that cache, for instance when that cache file already exists, then it takes at most a second. Which would be about right looking at the above timings.

Purging the Cache in OBIEE 10.1.3.4 on Linux

Hi,
I was trying to purge the cache from linux using ./nqcmd . Following is the error faced
*./nqcmd: error while loading shared libraries: libnqsgenericodbcinterface.so: cannot open shared object file: No such file or directory*
I have checked for the libnqsgenericodbcinterface.so in usr/lib directory. Its not present there. Is this the Obiee specific library file? Should it be present in usr/lib during the Installation?
Is there any work around for the same?
Thanks in advance.

Hi Ravi,
There might be some environment setup issues here.
Can you try running
/oracle/product/OracleBI/setup/common.sh
/oracle/product/OracleBI/setup/sysenvinit.sh
and see if the command runs fine later? I remember seeing this kind of case earlier and hence would like you to try
Hope this helps.
Thank you,

How do you ...properly....purge the cache?

I have PS CS4.
When I start my computer up, I always get the message that says,
"Bridge encountered a problem and is unable to read the cache. Please try purging the central Cache Preferences to correct the situation".
I've already "purged" the cache, I guess. But I keep getting the same message each time I start up my computer.
What am I supposed to do?
Thanks.

What did you do to purge the cache?
I would disable the auto startup for Bridge – it only causes problems.
And next time you start Bridge, hold down the Ctrl key as you click the icon and keep it down until you get a dialog . Select all options and see if things are better.

Purge the cache

Hi,
How to purge the cache in obiee 11g
thanks

Hi,
There are 2 ways to disable cache,
1)edit \OracleBI\server\Config\NQSConfig.INI, change to
===================================
[ CACHE ]
ENABLE = NO;
===================================
OR
2)uncheck the "Cacheable" checkbox on the property dialog of each physical tables and views
WILL METHOD 1 AND METHOD 2 RETURN SAME EFFECT ??
Specific report:
In the advanced tab of the report, under prefix you need to mention:
SET VARIABLE DISABLE_CACHE_HIT=1;

How to purge the cache daily

Hi all,
I have a simple question: Cause my ETL load data every morning, I'd like purge my cache with the same frequency, so the users can get fresh data in the reports.
Is there any procedure or variable in the configuration files to do that automatically?
Thanks,
Nazza

lets look at all your questions one by one
As the event polling table gets a row added for each table whose data is updated at the end of each ETL run, when exactly does the BI server purges cache related to that table - As soon as the polling happens and it finds a new record in your table
Lets say I set up a polling frequency (in Tools -> Utilities -> Oracle BI Event Tables) to every 60 minutes. At the end of every 60 minutes does the BI server restart by itself or does the polling take place without restart. - Polling takes place only when the server is up (there is no need to restart)
At the end of every 60 minutes does the BI server poll the event polling table whether or not any new rows are added to it? -(Yes )
What exactly happens when a new record is added to the event polling table in the database. - (The cache is purged )
If at the end of the ETL run data in 3 tables has changed, would 3 records be added to the event polling table in the database. - (yes , after the polling happens)
Let me know if you have more questions ...
Another way you can set it up is to create a batch file which would purge a table as its updated (use a procedure to capture the tables which have a value of 1 for update_type or use triggers to populate a table with these table names ) ...once purged you can set up your cache by using ibots (use javascripts) .

How to purge data cache table using command line

Hi:
Is there a way to purge the data cache table using command line?
thanks!

Thanks, Mike.
I'm thinking about the ldconsole provided with ALDSP.
The ldconsole has a link for purging the cache. Is there anything I can leverage from there? Is it a JMX component that I can call?

Purging the cache entries accordingto table and SA

Hi Gurus,
I have few questions on Cache purging
1>How many types of purging.
2>Is it possible to purge the cache based on tables i.e.(if entries are generated on table A only that entries should purge in cache manager).
3>Is it possible to purge the cache based on Subject Areas i.e.(if entries generated on subject area A only that entries should purge in cache manager).
4>supose in cache manager there are 100 entries and i want to purge only selected entries i.e.(if i want to purge 25th, 50th and 75th,100th entries ) how i can achieve this.
Regards,

The same you can get it from Helpfile
To purge the cache manually with the Cache Manager facility
Use the Administration Tool to open a repository in online mode.
Select Manage > Cache to open the Cache Manager dialog box.
Select Cache or Physical mode by selecting the appropriate tab in the left pane.
Navigate the explorer tree to display the associated cache entries in the right pane.
Select the cache entries to purge, and then select Edit > Purge to remove them.
In Cache mode, select the entries to purge from those displayed in the right pane.
In Physical mode, select the database, catalog, schema or tables to purge from the explorer tree in the left pane.
In Cache mode, you can purge:
One or more selected cache entries associated with the open repository.
One or more selected cache entries associated with a specified business model.
One or more selected cache entries associated with a specified user within a business model.
In Physical mode, you can purge:
All cache entries for all tables associated with one or more selected databases.
All cache entries for all tables associated with one or more selected catalogs.
All cache entries for all tables associated with one or more selected schemas.
All cache entries associated with one or more selected tables.
SAPurgeCacheByQuery. Purges a cache entry that exactly matches a specified query. For example, using the following query, you would have a query cache entry that retrieves the names of all employees earning more than $100,000:
select lastname, firstname from employee where salary > 100000;
The following call purges the cache entry associated with this query:
Call SAPurgeCacheByQuery('select lastname, firstname from employee where salary > 100000' );
SAPurgeCacheByTable. Purges all cache entries associated with a specified physical table name (fully qualified) for the repository to which the client has connected.
This function takes up to four parameters representing the four components (database, catalog, schema and table name proper) of a fully qualified physical table name. For example, you might have a table with the fully qualified name of DBName.CatName.SchName.TabName. To purge the cache entries associated with this table in the physical layer of the Oracle BI repository, execute the following call in a script:
Call SAPurgeCacheByTable( 'DBName', 'CatName', 'SchName', 'TabName' );
NOTE: Wild cards are not supported by the Oracle BI Server for this function. Additionally, DBName and TabName cannot be null. If either one is null, you will receive an error message.
SAPurgeAllCache. Purges all cache entries. The following is an example of this call:
Call SAPurgeAllCache();
SAPurgeCacheByDatabase. Purges all cache entries associated with a specific physical database name. A record is returned as a result of calling any of the ODBC procedures to purge the cache. This function takes one parameter that represents the physical database name and the parameter cannot be null. The following shows the syntax of this call:
Call SAPurgeCacheByDatabase( 'DBName' );
For Q4:
SAGetSharedRequestKey. An ODBC procedure that takes a logical SQL statement from the Oracle BI Presentation Services and returns a request key value.
The following shows the syntax of this procedure:
SAGetSharedRequestKey('sql-string-literal)

I purged my cache, how can I see thumbnails of my images again? Help!

I am a photographer and I should know more about my computer, but it is an iMac and it is new to me. My latest images were uploaded and when I tried to edit an image, a pop up kept coming up saying something about "the start up disk is full and you need to make room, etc.."
I decided to purge my cache within Adobe Bridge. Now, when I open bridge to view my images, it just shows them as a "CR2" file (I shoot RAW) and I am unable to see which image is which.
How can I fix this? I want to be able to view my images to see which one's I want to edit and save.
Thanks!
