Regarding caching mechanism - Pls respond ASAP.

Hi All,
I am trying to apply "purging of cache" on daily basis in my application because it is on transactional database. How could i proceed. I think if i am adding a event polling table and set the frequncy to 1 day then i can achieve that. But is there is any other way to do that automatically because i don't have scope to add another table in the database.
I have change the cache expiry of all physical table as 1 day. Is that will purge the cache every day or i need the event polling table.
Advance thanks on any suggestions.
Thanks
Ashok

Thanks John.
But we have migrated the system in production environemet. Thats why we can't run the script there everyday because no one has permission to access the server.
For this we have to explicitly take access and run the script. That is not possible as far as i see the production setup.
Is there any way to automate this.
Thanks
Ashok

Query Regarding Data transfer ( Pls Respond Quickly)

Hi,
I need to download the data to XML file. I have hard coded the file path in the Report Program. This Report should be shceduled for every night.
But the problem is that since I have hard coded the path, whenever the program is deployed to production system there will be a problem regarding the file path.
Can any body throw some light on how to avoid hard coding of the filepath ?
Reward points are assured.
Best Regards
Bhagat.

Hey Kishan,
In that Program the file path was hard coded. Can you let me know the alternate way so that I can avoid hard coding.
The thing is that that report should be scheduled for every night.

Hi,
I developed a web application using HTML5-Offline Application Cache mechanism. Inspite of deleting the cache as mentioned in the above steps, Firefox still maintains a copy of the page in it's cache. Also, a serious bug is, even though we delete all temp files used by Firefox, and open the previously cached page, it displays it correctly, but upon refreshing/reloading it again shows the previous version of the page maintained in the cache.

We have had this issue many, many times before including on the latest 3.6 rev. It appears that when the applicationCache has an update triggered by a new manifest file, the browser may still use only its local network cache to check for updates to the files in the manifest, instead of forcing an HTTP request and revalidating both the browser cache and the applicationCache versions of the cached file (seems there is more than one). I have to assume this is a browser bug, as one should not have to frig with server Cache-Control headers and such to get this to work as expected (and even then it still doesn't sometimes).
The only thing that seems to fix the problem is setting network.http.use-cache to false (default is true) in about:config . This helps my case because we only ever run offline (applicationCache driven) apps in the affected browser (our managed mobile apps platform), but it will otherwise slow down your browser experience considerably.

Suitable Caching Mechanism

Apoplogies if this is the wrong newsgroup. My J2EE App runs on Weblogic 8.1 and uses Oracle 9. It involves processing at times up to 50000 database records at a go. The Application applies an algorithm to each database record and then writes it's results to an output table which has a one to one mapping with the input table i.e I will be inserting about 50000 records. In order to improve performance I want to use JDBC batch inserts, however each output record is produced by a MDB (Message Driven Bean) from a pool.I guess I need a sort of cacheing mechanism which holds the records from the MDBs and some business logic to apply the JDBC batch insert to a chunk of the cache. I will probably need a timed event to perform this "flushing" of the cache periodically. Anybody have experience of doing something similar or able to provide a more elegant solution to the problem?
TIA

Hi Sailendra,
In this case you can make use of BPM object if I understood your question correctly.
In the component Cataloge make a BPM object and under that create attribute/attributes/array. Then the value you want to save/store keep it in a bpm object attribue and pass the bpm object from one process layer to another/as per your requirement. ex: bpmobject.attribute1Name = "Bibhu";
You can acccess those values in another process/activities by bpmobject.attributeName
bpmobject is the object that you created and the instance variable is of type created bpmobject.
attributeName is the attribute where you stored the value.

Regarding Cache in clustering

Hi,
we are using JOC Cache mechanism for java objects
In Standalone application server 10.1.3.1 it is working fine
In production we are using OC4J Enterprise edition Cluster topolgy (10.1.3.1.0)
In this case we are using multiple oc4js and those oc4js we have 2 instances and 2 jvms.
in cache wise we are using in-memory concept,
we have a senario where at run time cache object values will be changed.
i have observerved that in each jvm one cache region created.
when one cache is created then it is not reflecting in another jvm (or instance)
i want to replicate when ever one region's object modified to other jvm instances
can u please provide any solution for this problem
Regards
Mannu.

Chak,
Try to understand the concept of BI reporting here. Your reports makes use of all the tables i.e. Dim & Fact to fetch the resultset and it is the report SQL which gets cached.
If a query references multiple physical tables with different persistence times, the cache entry for the query will exist for the shortest persistence time set for any of the tables referenced in the query. So, in this case it will be just 1 Day for all the tables and complete SQLs referencing these tables.
For NQCMD command utility...Purging is very easy here...and same goes for seeding.
Like SeedTableCache.txt which will have your SQL scripts. Once this is used via NQCMD which can be scheduled using Job Manager or any other job.
nqcmd -d AnalyticsWeb -u Administrator -p Administrator -s c:\obiee\SeedTableCache.txt
Similar concept goes for any flavor of BI.
Here John has given some good examples on Cache Mgt.

IPod nano problems! PLEASE RESPOND ASAP!!

HELP!
A couple days ago I had to re-format the computer due to a virus. I didn't save any of the songs that were on iTunes. That night I listened to some songs on my iPod. The next day I plugged it in my computer for it to charge. When it was done charging, I went to listen to some songs but there were NO SONGS ON IT!! I have no clue what happened... has this happened to anyone? Does anyone know how to fix it? Please respond ASAP!
Thanks,

Hi Molly,
Welcome to Apple Discussions
Copying songs from your iPod to your computer
"The iTunes library on your computer holds all the songs you've encoded from your CD collection or purchased from the iTunes Music Store. With default settings, iTunes automatically copies the songs in your library to your iPod. When you use your iPod as a hard disk, you can't see the songs iTunes copies to your iPod in the Finder or My Computer. This is normal. Using the Finder or My Computer, you can't copy these song files from your iPod back to iTunes or to any other computer. The synchronization between your iPod and your computer is always one way: from iTunes to iPod.
If you've erased the music library on your computer, there's no way to use the Finder or My Computer to copy the songs from your iPod to reconstitute the library on your computer. One solution is to encode the songs from your CD collection again, then sync your new library with iPod. If you purchased songs from the iTunes Music Store and didn't back them up, there's no way to download them again. You'll have to buy new copies of the songs."
Taken from Using your iPod as a hard disk
So even if there were any tracks on your iPod, Apple has set it so you shouldn't be able to get them back.
You need to reload iTunes with music, and then get into the habit of backing them up as well. Once you've done that you can start loading onto the nano.
To help with backing up your music this link will explain what the files are:
What are the iTunes library files?
If you have problems with your nano here is a useful link:

JNDI as a caching mechanism

Hi,
We are building an application using stateless session beans to access some
back end systems. The backend transaction is rather expensive with regards
to execute time. To optimize response times we are looking at a caching
strategy, we have identfied the following implementation alternatives :
1. Create object cache implementations as statefull session beans, storing a
reference to them in JNDI.
2. Create object cache implementations as regular java objects and storing
the entire object in JNDI.
Which one of these alternatives we choose will rely on the performance of
the WL JNDI, we are using the 5.1 server. If WL JNDI is capable of handling
reasonable amounts of data there should be no reason to use the expensive
statefull session beans.
Q1 : Are there any method to calculate the amount and troughput of data that
would be possible using alternative 2 ?
Q2 : Are there any other mechanism we should consider ?
Any help would be greatly appreciated
Regards,
Anders Mathisen

Read-Only entity beans are the entity beans which never call ejbStore() and
ejbLoad() is only called when timeout is expired (or never).
If you want to cache data for the session only you can use HttpSession - in
the cluster all requests are pinned to the server which originated the session
until this server fails. To minimize replication overhead you can use transient
fields or use the fact that replication happens only when session attribute is
set() - you can associate a cache object with the session and lazy populate it
later.
Anders Mathisen <[email protected]> wrote:
hi,
thanks for the response, what do you mean by read-only entity beans ?
Beans that are loaded with data manually (from eg. a stateless session
bean), and just used as a dataholder ?
I forgot to mention in the previous article that the caching mechanism here
needs only be local to a single users session. That is a session will never
use cached data from another session.
Althoug even if we have the requirement above, some caching mechanism
allowing for sharing of data could be handy here, this is not an absolute
requirement.

Rob Woollen <[email protected]> skrev i

Stateful session beans should not normally be used as a cache. A
stateful session bean instance is associated with a single user.
I wouldn't use JNDI as a caching mechanism either.
My suggestion would be Read-Only entity beans.

How to build cache mechanism

Hello all
i have application that basically loading very big object that contains sub objects and
doing dynamic lookup by name of the object and the method i like to invoke and then invoke it
everything done ofcorce with reflection .
now this application will be called handeret times per minute .
some questions .
first of all do i need caching mechanism? for saving the subobject that had bean called in some kind of vector in memory for example or if i use reflection , i dont need caching mechanism .
second question is do i need threads here ? if i do , how i buid some kind of locks to this threads ?
thanks

I'd use the Flyweight pattern here. It sounds like you're retrieving a lot of data that's related to other data through some kind of index. A Data Transfer Object (DTO) is a Flyweight class that could hold all of the information required to retrieve the "sub-objects" as you call them, but not until they're needed. It's a little more detailed to make sure that the objects are available when you need them, but obviously the network bandwidth/latency issues are causing a severe performance impact. I'm using EJBs in this example, but it will apply to anything where large amounts of related data are used in the application.
// EJB Entity bean
public abstract class EJBEntity extends EJBObject {
    public abstract Integer getId();
    public abstract String getStringData();
    public abstract Collection getChildObjects(); // "heavyweight" data
// Data Transfer Object
public class EJBEntityDTO {
   private int id;
   private String stringData;
   private int[] childIds;
// some application code
id = ...
EJBEntityDTO dto = transferEJBData(id);
EJBEntityDTO childDTO = transferEJBData(dto.childIds[0]);
...It's definitely more work to do it this way, but it's the only way to avoid fetching the entire collection when you only need one child object.

What is the caching mechanism firefox 3.6 uses compared to what IE 6/7 and 8/9 use?

I just need to know how firefox handles/takes care of/and does its work with cookies and cache, basically its caching mechanism. Also comparing it to IE versions 6/7 and 8/9 would help, for the sake of web development with respect to the two browsers (Detailed technical answer would help). Since web apps may sometimes work on firefox and sometimes not while it works in IE just fine.
