Breaking FMS Caching For Specific Video(s)

We occasionally run into a condition that appears to require cache breaking. If a user rotates a video that has been recently played and the video is currently in the FMS cache, subsequent requests for the video will continue to show the unrotated video.
Is there a way to break the FMS cache for a specific video? If not, I would be equally curious for a way to clear the cache completely, though this is going to cause a much larger performance hit than I would hope for.

Programatically validate/invalidate cache for specific query

Hi,
I am looking to programatically invalidate and re-instantiate the cache for a specific query.
I know how to perform this manually via RSRT, RSRT1/2....etc. What I am looking for is a way to schedule this and programatically control caching on specific query.
Any help would be wonderful!!
Thanks!

hi Dong Suk Choi ,
the technical information which u have furnished clearly says that the settings
that u have made does not enable the query to use cache.
u can enhance cache by customizing the inforovider or in the transaction rsrt
even if the concerned query does not have required settings u can make them in rsrt tcode.
goto rsrt set the read mode and cache mode as u wish, however default settings would give optimum performance.
and run the query.
in the rsrt screen a push button execute + debug enter that and unmark the check box do not use cache.
hope this helps.
reward points if helpful.
bye.

"Accessed denied" for Windows Media Player in Firefox for specific video

I get an "Access denied" error message after the video loads, it plays the intro video and the I get the error. Why?
Specifically, here: http://www.gamespot.com/pages/video_player/popup.php?sid=6145418&pid=927204
The video will appear, show the intro, then give the "Access denied" error message. This happens to me in Firefox 1.5.

Install Flip4Mac WVM, http://www.flip4mac.com/, and see if that fixes the Safari problem. As I mentioned earlier, all trailers play without any problem.

Securing Specific Videos by Username and Password

We currently have an FMS instance setup and running on AWS. We provide for a number of clients and one has queried if it is possible to secure their videos in some way. We are using Strobe Media Player to stream the videos which I assume will effect the outcome. Could someone please provide me with some details on how best to achieve this.
Many thanks in advance,
Steven

One of the ways to autheticate users for specific video is to send the "user-name" & "password" as parameters to connect URI and authenticate using auth plugin. You can process the connect URI under "IFmsAuthEvent::E_PLAY:" case and depending upon the stream name (which can be obtained from F_STREAM_NAME ) you can authenticate the users.
Please refer the auth plugin manual for more information : http://help.adobe.com/en_US/flashmediaserver/devguide/WS5b3ccc516d4fbf351e63e3d11a0d662434 -7fe8PluginAPI.html

I need to increase my FMS buffer size for display video smoothly

I need to increase my buffer size in FMS.
Please let me know form where i would be increase my FMS buffer size.
My video is running from RTMP and i faces the problem to load. video stalled between the running. so i need to increase buffer size for running video smoothly.
Please reply me as soon as possible so i can resoled my problem.
Thanks in advance.....

Hi,
You can increase the buffer size by using the property bufferTime of NetStream Object you are using. For eg: if ns is your NetStream Object then it can be done by ns.bufferTime=<desired value>.
Also you can go through this

Purge Cache for a Specific Business Model

Hi everyone,
I have a obiee(11) report purging all cache entries (as Call SAPurgeAllCache()). Is there a method to purge cache partially for specific business model entries and not to purge all the cache ?
Thanks ...

Hi,
To selectively purge, you could use SAPurgeCacheByQuery, SAPurgeCacheByTable or SAPurgeCacheByDatabase. Alternatively, Event Polling Tables may help. See http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1005542 and http://docs.oracle.com/cd/E23943_01/bi.1111/e10541/querycaching.htm#i1010207.
Also see the section on BI Server caching here : http://www.rittmanmead.com/2013/03/optimising-obiee-performance-tuning/
SET VARIABLE DISABLE_CACHE_HIT = 1
It will purge the cache for that report.This is just wrong. DISABLE_CACHE_HIT only DISABLES cache use for the query execution, it does not PURGE it
You may go for this DISABLE_CACHE_SEED for more info http://docs.oracle.com/cd/E23549_01/bi.1111/e10540/variables.htm
What's the point of DISABLING use of the cache, if the OP wants to use the cache?
set the cache persistence time for the related physical tables. so based on the time interval u set, at that time specific tables only will get cache purged.This is only the time from which the entry got loaded into the cache, so is not a good way to manage the purging of the cache usually - because it has no relation to when the data got loaded to the database

Detecting Bandwidth Quality for Live Video Streaming

Hi,
We have an application that is using FMS to share slides (swf,jpg, etc) with another client. We added a video as an option. We would like to verify as often as possible the bandwidth quality between communications in order to suggest the user to close video if we notice bandwidth is not optimal.
We've been experimenting doing a bandwidth detection every 60 seconds, but I am wondering if there are specific guidelines to do this for live video, like how many times one should verify bandwidth? Is it ok to take one reading or should we take a few readings and then average out?
Taking into consideration that every time we test bandwidth fms seems to flood the connection to figure out the bandwidth, I was wondering if anyone has some insight into this.
Kind regards.
+LA

Please find the best practices for dynamic streaming at this place

Let me know if that doesn't suits your need, then I will try to figure out something else for you.

H264 profile for mp4 videos on mac firefox?

I have some videos which are not playing on firefox beta on MAC 10.10. Can somebody tell me what is the exact profile and settings needed to be set for H264 video?

HI hello512,
It does not sound like a general error because with the same set up I can view this file example: [http://techslides.com/demos/sample-videos/small.mp4]
Are any of the following interfering with the videos:
# After you Clear the cache
# Disable interfering extensions or ad-blocking software
# Check some Firefox settings, specifically the cookie preferences in the Privacy section of Preferences in Firefox.
Are there any content preferences that may be saved to save mp4 files within Firefox: [[Applications panel - Set how Firefox handles different types of files]]

How to create a cache for JPA Entities using an EJB

Hello everybody! I have recently got started with JPA 2.0 (I use eclipseLink) and EJB 3.1 and have a problem to figure out how to best implement a cache for my JPA Entities using an EJB.
In the following I try to describe my problem.. I know it is a bit verbose, but hope somebody will help me.. (I highlighted in bold the core of my problem, in case you want to first decide if you can/want help and in the case spend another couple of minutes to understand the domain)
I have the following JPA Entities:
@Entity Genre{
private String name;
@OneToMany(mappedBy = "genre", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<Novel> novels;
@Entity
class Novel{
@ManyToOne(cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Genre genre;
private String titleUnique;
@OneToMany(mappedBy="novel", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> editions;
@Entity
class NovelEdition{
private String publisherNameUnique;
private String year;
@ManyToOne(optional=false, cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Novel novel;
@ManyToOne(optional=false, cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Catalog appearsInCatalog;
@Entity
class Catalog{
private String name;
@OneToMany(mappedBy = "appearsInCatalog", cascade = {CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> novelsInCatalog;
The idea is to have several Novels, belonging each to a specific Genre, for which can exist more than an edition (different publisher, year, etc). For semplicity a NovelEdition can belong to just one Catalog, being such a Catalog represented by such a text file:
FILE 1:
Catalog: Name Of Catalog 1
"Title of Novel 1", "Genre1 name","Publisher1 Name", 2009
"Title of Novel 2", "Genre1 name","Pulisher2 Name", 2010
FILE 2:
Catalog: Name Of Catalog 2
"Title of Novel 1", "Genre1 name","Publisher2 Name", 2011
"Title of Novel 2", "Genre1 name","Pulisher1 Name", 2011
Each entity has associated a Stateless EJB that acts as a DAO, using a Transaction Scoped EntityManager. For example:
@Stateless
public class NovelDAO extends AbstractDAO<Novel> {
@PersistenceContext(unitName = "XXX")
private EntityManager em;
protected EntityManager getEntityManager() {
return em;
public NovelDAO() {
super(Novel.class);
//NovelDAO Specific methods
I am interested at when the catalog files are parsed and the corresponding entities are built (I usually read a whole batch of Catalogs at a time).
Being the parsing a String-driven procedure, I don't want to repeat actions like novelDAO.getByName("Title of Novel 1") so I would like to use a centralized cache for mappings of type String-Identifier->Entity object.
Currently I use +3 Objects+:
1) The file parser, which does something like:
final CatalogBuilder catalogBuilder = //JNDI Lookup
//for each file:
String catalogName = parseCatalogName(file);
catalogBuilder.setCatalogName(catalogName);
//For each novel edition
String title= parseNovelTitle();
String genre= parseGenre();
catalogBuilder.addNovelEdition(title, genre, publisher, year);
//End foreach
catalogBuilder.build();
2) The CatalogBuilder is a Stateful EJB which uses the Cache and gets re-initialized every time a new Catalog file is parsed and gets "removed" after a catalog is persisted.
@Stateful
public class CatalogBuilder {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private Cache cache;
private Catalog catalog;
@PostConstruct
public void initialize() {
catalog = new Catalog();
catalog.setNovelsInCatalog(new ArrayList<NovelEdition>());
public void addNovelEdition(String title, String genreStr, String publisher, String year){
Genre genre = cache.findGenreCreateIfAbsent(genreStr);//##
Novel novel = cache.findNovelCreateIfAbsent(title, genre);//##
NovelEdition novEd = new NovelEdition();
novEd.setNovel(novel);
//novEd.set publisher year catalog
catalog.getNovelsInCatalog().add();
public void setCatalogName(String name) {
catalog.setName(name);
@Remove
public void build(){
em.merge(catalog);
3) Finally, the problematic bean: Cache. For CatalogBuilder I used an EXTENDED persistence context (which I need as the Parser executes several succesive transactions) together with a Stateful EJB; but in this case I am not really sure what I need. In fact, the cache:
Should stay in memory until the parser is finished with its job, but not longer (should not be a singleton) as the parsing is just a very particular activity which happens rarely.
Should keep all of the entities in context, and should return managed entities form mehtods marked with ##, otherwise the attempt to persist the catalog should fail (duplicated INSERTs)..
Should use the same persistence context as the CatalogBuilder.
What I have now is :
@Stateful
public class Cache {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private sessionbean.GenreDAO genreDAO;
//DAOs for other cached entities
Map<String, Genre> genreName2Object=new TreeMap<String, Genre>();
@PostConstruct
public void initialize(){
for (Genre g: genreDAO.findAll()) {
genreName2Object.put(g.getName(), em.merge(g));
public Genre findGenreCreateIfAbsent(String genreName){
if (genreName2Object.containsKey(genreName){
return genreName2Object.get(genreName);
Genre g = new Genre();
g.setName();
g.setNovels(new ArrayList<Novel>());
genreDAO.persist(t);
genreName2Object.put(t.getIdentifier(), em.merge(t));
return t;
But honestly I couldn't find a solution which satisfies these 3 points at the same time. For example, using another stateful bean with an extended persistence context (PC) would work for the 1st parsed file, but I have no idea what should happen from the 2nd file on.. Indeed, for the 1st file the PC will be created and propagated from CatalogBuilder to Cache, which will then use the same PC. But after build() returns, the PC of CatalogBuilder should (I guess) be removed and re-created during the succesive parsing, although the PC of Cache should stay "alive": shouldn't in this case an exception being thrown? Another problem is what to do when the Cache bean is passivated. Currently I get the exception:
"passivateEJB(), Exception caught ->
java.io.IOException: java.io.IOException
at com.sun.ejb.base.io.IOUtils.serializeObject(IOUtils.java:101)
at com.sun.ejb.containers.util.cache.LruSessionCache.saveStateToStore(LruSessionCache.java:501)"
Hence, I have no Idea how to implement my cache.. Can you please tell me how would you solve the problem?
Many thanks!
Bye

Hi Chris,
thanks for your reply!
I've tried to add the following into persistence.xml (although I've read that eclipseLink uses L2 cache by default..):
<shared-cache-mode>ALL</shared-cache-mode>
Then I replaced the Cache bean with a stateless bean which has methods like
Genre findGenreCreateIfAbsent(String genreName){
Genre genre = genreDAO.findByName(genreName);
if (genre!=null){
return genre;
genre = //Build new genre object
genreDAO.persist(genre);
return genre;
As far as I undestood, the shared cache should automatically store the genre and avoid querying the DB multiple times for the same genre, but unfortunately this is not the case: if I use a FINE logging level, I see really a lot of SELECT queries, which I didn't see with my "home made" Cache...
I am really confused.. :(
Thanks again for helping + bye

I imported videos from photo into iMovie when I set up iMovie (obvious mistake) and now iMovie doesn't work properly, nor can I move specific videos into a folder where I want them. How do I fix this?

I imported videos from photo into iMovie when I set up iMovie (obvious mistake) and now iMovie doesn't work properly, nor can I move specific videos into a folder where I want them. How do I fix this? I even tried deleting iMovie, bought a new copy and installed it, but the folder "iPhoto Videos" is still there and I can't get new clips loaded to iMovie, especially where I want them. Please help.

The iPhoto Videos do occasionally have problems. I've seen a lot of people write messages to this Discussion group describing similar problems. The only thing that seems to get around this problem is to pull the video clips out of iPhoto then import them directly into iMovie. Once the troubles with iPhoto Videos starts, I haven't yet seen anyone write back with something that they did to fix it.
The most difficult part of doing this is the movies in iPhoto might be a little difficult to track down. But you can create a smart alum that does that for you. Go to iPhoto > File Menu > New Smart Album:
Set the first pulldown menu to keyword, second to contains, then in the last box type Movie with a capital 'M'. Then click OK. This smart album more or less does as search of the whole iPhoto Library and only displays items that match your search tearm of "Movie" exactly. In that smart album then you can find the original Movies you want to move out of iPhoto and into iMovie, <CTRL> click on the Movie clip, then choose Reveal in Finder. That will jump you out of iPhoto temporarily and into the iPhoto Library folder. From there you can move that movie file to the desktop. Move all the clips you want, once they're all collected up go to iMovie and go to the File Menu > Import Files. Then point it to the desktop where you moved your video clips.
This will put all those videos into an Event folder in iMovie and bypass iPhoto Videos altogether.

Seeding the cache for all users

We are facing some performance issues (even after using aggregate tables) and are looking into seeding the cache for all users so that the dashboard pops up immediately.
So far I couldn't make it work. As Administrator I created an iBot to run a report for 1 month (dashboard has a dashboard prompt on the period) with Data Visibility set to 'Personalized (individual data visibility)' as I understood from the manual this is the way to seed the cache for all users. Now when I log on with my personal userid and set the prompt value to that specific period it is not using the cache.
Obviously destination was set to 'Oracle BI Server Cache' and cache has been turned on.
Does anyone have any suggestions ?
