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,
Dhar

OR
2)uncheck the "Cacheable" checkbox on the property dialog of each physical tables and views

Purging the Cache on Solaris

How to purge the cache in a way that no server restart is required?
OS: SUN SOLARIS

http://obiee101.blogspot.com/2008/03/obiee-manage-cache-part-1.html
nqcmd also is available in Unix OBIEE instalations under ./OracleBI/server/Bin.

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.

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.

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)
Pls mark if helps

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) .

I have master suite cs6. on mac osx. bridge has been quitting unexpectedly. Also, getting message at start up that states that "bridge encountered a problem and is unable to read the cache. Please try purging the central cache in Cache Preferences to correct the situation" I have purged the cache several times and adjusted settings with no change. I also downloaded the entire suite and installed. Do I need to uninstall all of the programs before installing the suite? There is not an option to install only Bridge from the install package.

Purging the central cache in Bridge

When opening Bridge I am getting the message: "Bridge encountered a problem and is unable to read the cache. Please try purging the central cache in Cache Preferences to correct situation."
I have a system of very extensive labels in Bridge and it would be a major problem for me to lose the labels. My question is, if I select in preferences "Purge Cache", will this affect the labels and ratings in my files?
I also found where I can hold the Option key on Mac when starting Bridge. It appears this gives options to "Reset Preferences" and/or "Purge Entire Thumbnail Cache". If I select "Purge Entire Thumbnail Cache" but NOT "Reset Preferences" will this result in purging the cache but not affect my labels?
From my research it definitaly appears I need to avoid resetting preferences while purging thumbnails. On the forum it states:
Reset Preferences
Returns preferences to their factory defaults. Some labels and ratings may be lost. Adobe Bridge creates a new preferences file when it starts.
Bridge CC 6.0.1.6
OSX 10.8.5

Like I stated earlier Mac's seem to have more problems with cache than win sys.
Try this
Quit Bridge, from user library (NOT system and root library) preferences folder find and delete the Bridge5.plist file manual. Do this also in same user library caches folder (Caches/Adobe/Bridge CS6) and inhere find and the folder called 'cache' and drag it to the trash.
restart Bridge holding down option key and choose reset preferences, then try again.
Here is doc on resetting pref. http://helpx.adobe.com/bridge/kb/resetting-bridge-preferences-using-command.html
From posts I have read lables can just dissapear for no reason. You do have backups don't you?
Have never heard from anyone that they have lost labels with resetting prefernces.

Why do I get an error message about 'purging the central cache' everytime I open Bridge?

Whenever I open Bridge I get an error message about the cache not being able to be read and that I should try purging the central cache in Cache Preferences.
I've looked at the Cache Preferences and purged the cache as it suggested, but this message comes up every time I open Bridge. Any help gratefully received.
Cheers,
Cathie

Your central cache file seems corrupted and you ave to delete this manual. Regarding your screenshot you seem to be on a Mac.
Per OSX 10.7 the user library is hidden, if you don't have your user library in view use menu go in Finder with option key to reveal this library.
Quit Bridge, go to your user library (user (your username) / library / Caches/ Adobe/ Bridge CSxx (your version) and inhere are a plug in file and a folder called Cache.
Drag both files outside of the library (preferable to the trash) and restart Bridge. This creates both deleted files again but the cache folder is empty and you need to recache your files again (takes a bit of time) but then you should be OK.
