Isolated client session & caching

I have a 3-tier TopLink application that uses isolated client sessions and stateless EJBs with CMT. A separate client session is created for each EJB method call via server.acquireClientSession(). To retrieve a persistent object for read-only purposes, the application uses the client session. To retrieve a persistent object for read/write purposes, the application uses the UnitOfWork returned by clientSession.getActiveUnitOfWork(). Within the same EJB method call, retrieving the same persistent object via the client session and the UnitOfWork causes the same SELECT to be issued twice.
I noticed that the parent session of the UnitOfWork returned by clientSession.getActiveUnitOfWork() is not clientSession My guess is that this causes objects retrieved via the UnitOfWork to not be stored in clientSession's cache.
Why is the parent session of the UnitOfWork returned by clientSession.getActiveUnitOfWork() not equal to clientSession? Could the duplicate SELECT be avoided if the parent session was clientSession?

Hello,
Instead of calling getActiveUnitOfWork() call acquireUnitOfWork on the clientSession. The acquired UnitOfWork will have the clientSession as the parent. The method getActiveUnitOfWork() goes to the TopLink CMT interface objects to acquire the UnitOfWork. This UnitOfWork is available throughout the transaction and as such is created with a different parentage.
If you would like to share the same UnitOfWork and ClientSession throughout the Transaction then you could call getActiveUnitOfWork on the serverSession (instead of acquireClientSession) then get the parent and execute your read-only queries on that ClientSession.

Using the Client Result Cache

Hello everyone,
I have a question regarding the use of the client result cache but first of all here are the informations about my database:
SQL> SELECT * FROM v$version;
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0    Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
I have installed the Oracle Client Tools on my clientmachine. It has a tnsnames.ora like this:
ORCL =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = FEA11-119SRV)(PORT = 1521))
    (CONNECT_DATA =

The Client Result Cache is configured in the sqlnet.ora.

After configuring client an server I try the followign SQL-Statement on the clientmachine:
sqlplus oracle/password@orcl
set autotrace traceonly explain
SELECT /*+ result_cache */ *
FROM testtable;
SQL
The execution plan show two operations: "SELECT STATEMENT" and "TABLE ACCESS FULL" but no the "RESULT CACHE" operation.
Did I miss something?
Any help would be appreciated

result_cache_max_size           0
That means the result cache is disabled. You need to set it to a non-zero value. That is the maximum ammount of memory, in bytes, the database will allocate on the shared pool to dedicate it to the result cache for all requests.
By the way, OCI_RESULT_CACHE_MAX_SIZE is optional. By default the sessions will have the maximum size they can occupy on the cache determined by CLIENT_RESULT_CACHE parameter, the client (OCI) side parameters override that.
result_cache_mode           MANUAL
Another thing to consider is RESULT_CACHE_MODE in MANUAL, that will cause only the statements with the RESULT_CACHE hint on it to be cached on the result cache. You can also set result cache to mode FORCE on specific tables with alter table command.

Possible session caching issue in SSRS2014

Using custom FormsAuth, User A can sign into our own main asp.net mvc app (WIF cookie), then SSRS (FormsAuth cookie) and all is well. Here is where things go bad. User A signs out of our main application (WIF cookie deleted) then back in into
our main application as User B then back into SSRS. SSRS report that displays User!UserID show UserA instead of current User B. Its like there is either a session or cookie caching issue going on but not for sure.
1. What is the proper way to sign out of SSRS and prevent session caching?
2. Do I need to worry about making my SSRS logon page non-cacheable? If so, what is the recommended way of doing this?
thanks
scott

Hi scott_m,
According to your description, you used custom FormsAuthentication in Reporting Services, after user A sign out the application an sign in as user B, SSRS built-in user is shows user A instead of user B.
Based on my search, once we configured SSRS to use Custom (Forms) authentication by deploying a custom security extension, we can logon to MS Report Manager (MSRM) using credentials of our custom security framework via a logon web page. But there is no way
to logout or to expire the authentication cookie, so we need to close the browser manually. As a workaround, we can add a logout button to the Report Manager which is using Forms Authentication, then use code to clear the cookie and redirect to home page.
In addition, if you extend Reporting Services to use Forms Authentication, it’s better to use Secure Sockets Layer (SSL) for all communications with the report server to prevent malicious users from gaining access to another user's cookie. SSL enables clients
and a report server to authenticate each other and to ensure that no other computers can read the contents of communications between the two computers. All data sent from a client through an SSL connection is encrypted so that malicious users cannot intercept
passwords or data sent to a report server.
Here is a relevant thread you can reference:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/5e33949d-7757-45d1-9c43-6dc3911c3ced/how-do-you-logout-of-report-manager

Using the client result cache without the query result cache

I have constructed a client in C# using ODP.NET to connect to an Oracle database and want to perform client result caching for some of my queries.
This is done using a result_cache hint in the query.
select /*+ result_cache */ * from table
As far as I can tell query result caching on the server is done using the same hint, so I was wondering if there was any way to differentiate between the two? I want the query results to be cached on the client, but not on the server.
The only way I have found to do this is to disable all caching on the server, but I don't want to do this as I want to use the server cache for PL/SQL function results.
Thanks.

You haven't provided ANY information about how you configured the result cache. Different parameters are used for configuring the client versus the server result cache so you need to post what, if anything, you configured.
Post the code you executed when you set the 'client_result_cache_lag' and 'client_result_cache_size' parameters so we can see what values you used. Also post the results of querying those parameters after you set them that show that they really are set.
You also need to post your app code that shows that you are using the OCI statements are used when you want to use client side result cacheing.
See the OCI dev guide
http://docs.oracle.com/cd/B28359_01/appdev.111/b28395/oci10new.htm#sthref1491
Statement Caching in OCI
Statement caching refers to the feature that provides and manages a cache of statements for each session. In the server, it means that cursors are ready to be used without the need to parse the statement again. Statement caching can be used with connection pooling and with session pooling, and will improve performance and scalability. It can be used without session pooling as well. The OCI calls that implement statement caching are:
OCIStmtPrepare2()
OCIStmtRelease()

Http.keepAlive does not turn off SSL session cache?

Hi there,
I have a web service client that uses JSSE for making web service calls via https. In an effort to debug problems, I set http.keepAlive to false, I can see from the SSL debug output that KeepAlive timer messages no longer shows up, but I still see text such as "Cached client session" and "try to reuse cached session", etc.
Should not turning off keepAlive disable the use of persistent sessions?
Thanks.
Yan

They are unrelated features.
HTTP Keep Alive allows the browser to maintain a Socket to the server and issue multiple HTTP requests over that same socket.
SSL Session caching is when an SSL Session is assigned an ID, and additional SSL connects may be established with the same ID. These additional sockets then do not need to perform the full SSL handshake, since much of the data has already been negotiated previously.

How to add a new object to Toplink session cache?

Toplink Experts,
I have a question on Toplink 9.0.4.5 (I know this is older version of Toplink but this is what we are using right now). Let me give you little context before I ask the question.
Toplink server session brokers client sessions (that are spawned by it) and gets changes made in client sessions into server session through transaction commits. Process involved in getting some thing into database using Toplink is: 1) Get client session 2) Register object to be written into database with Toplink's UnitOfWork (UOW). This registration creates two copies of the object registered (original object). Working clone for client application for modifications, backup clone for Toplink to compare the changes made to the working clone later 4) Make changes to the working clone 5) Complete the transaction (and so commit UOW). If transaction commits successfully, Toplink writes the changes from the working clone into database first and applies the same changes made to the working clone to the original object in Toplink server session cache next. Oracle recommends using UOW to write some thing into database. Using UOW involves a transaction and it writes changes into database first before the original object in Toplink server session cache is refreshed.
Now comes my question: Is there a way to add a brand new object (persistent object) into Toplink server session cache with out writing it first into database? I am OK if I need to use UOW and also to use transaction to make the change but I just want to be able to refresh the original object in the server session cache with out writing any thing into database. If there is a way to do this? What are the disadvantages in doing this way though? I have read Oracle's Toplink developer guide (10.1.3) and Javadocs from Oracle on UnitOfWork/Session etc all related interfaces and classes but I could not find a way. Please help!
Syam

There are a couple things wrong with the method you posted. The first being uow.registerObject() is going to cause the object to be treated as new if you are not using the TopLink cache.
There really is not any supported mechanism to do what you are looking to do. TopLink 11g has the hooks to replace the TopLink cache with a distributed cache (and the TopLink-Grid product uses these to use Coherence as the TopLink cache) but earlier versions did not have this.
If you are willing to work outside what would be officially supported and no component of the application is using the ServerSession cache (ie all queries refresh) then something like the following may work for you:
public void prepareObjectForSave(Object userEditedObject, Object gigaSpacesObject)
UnitOfWork unitOfWork = this.dbContext.getSession().acquireUnitOfWork();
Descriptor descriptor = this.dbContext.getSession().getDescriptor(gigaSpacesObject);
Object pkVector = descriptor.getObjectBuilder().extractPrimaryKeyFromObject(gigaSpacesObject, this.dbContext.getSession());
Object cloneOfMostRecentlyUpdatedObject = (Object)unitOfWork.cloneAndRegisterObject(gigaSpacesObject, new CacheKey(pKVector), descriptor);
unitOfWork.mergeCloneWithReferences(userEditedObject);
unitOfWork.commit();
}You will need to tweak the above code to have it match the APIs in your version of TopLink and you should test thoroughly.

Client Session Not getting expired in OBI EE 10.1.3.4.1

Hi All,
I haave placed the below tag in the instanceconfig.xml file, but the client session is not getting expired.
Can you please help me on the same.
Our test environment OBI is enabled with the Site minder SSO.
<ClientSessionExpireMinutes> 60</ClientSessionExpireMinutes>
Thanks in Advance
Siva

Siva,
There can be many factors for this: 'ClientSessionExpireMinutes'
Defines the length of idle time that can pass before Oracle BI Presentation Server removes the user's client (browser) session information from its memory. This session includes user-specific state information such as request cache - dashboard page state - subject area information -connection information - and so on.
Make sure while testing you are not doing anything on OBIEE browser window i.e. its idle
Also, try to increase the minutes to say 240 and check how much time it takes ...??
This shud solve..as this is very common problem with such tags..its not 100% guranteed !!

Information kept in client browser cache

Hi all,
Does anyone know what kind of information is stored in client browser cache when users are logged into Planning or Workspace?
We have a concern from customer Information Security department concerning to confidential information (data) that could be left behind on browser cache when users log out from applications.
We need to provide a confirmation to customer that all confidential information that could be found on client browser cache is deleted after the users end their work sessions.
Thanks in advance,
Marilia

The question is what counts as confidential information.
You can use the Firefox browser to login and go to Planning and then in another tab do about:cache
Using this the below web pages are in the cache. I browse through these cached pages and one of them has application name and database names which some people may consider confidential depending on the context.
Suggest you provide them a view only login and ask them to use Firefox and let them determine if that information is confidential.
The cached information from my session follows:

SSL Session cache persistence

Hello,
I've been scratching my head for while on a problem concerning SSL session caching. Upon examining memory usage of the session cache I noticed that the number of cached sessions is reset at some point while new session are created. For example sometimes at around 300 -1500 sessions the number drops to under 10. I have set the session cache size to unlimited (via SSLSessionContext.setSessionCacheSize()) and session timeout to 24 hours (via setSessionTimeout()).
I noticed that this has probably something to do with garbage collection. I made a server application that receives SSL connections and every few seconds prints the number sessions in the cache and the amount of consumed memory (in megs). I also enabled garbace collection information printing and ran java VM with a maximum heap size of 512M. I ran a client application against it that continuously initializes a new sessions. Here's what I got:
Sessions: 484     Memory: 1.7913589477539062

And in between there's a garbage collection print "[Full GC...". Why is this? Shouldn't the session cache keep the sessions until there's either too many of the them or they get too old? Here only a few minutes have elapsed and memory consumption is under control (1 to 3 megs).

In my implementation I avoid session renegotiation as
much as possible to achieve high throughput. My goal
is to preserve sessions for the entire session
timeout time. This raises a few questions:Understood, but you also have to protect the server against resource exhaustion. It's in the client's interest to cache lots of sessions for a long time; the server's interest is to conserve resources so it can keep itself running.
You actually don't want to cache all the sessions, just the 'hot' ones, so you're better off having the SessionContext remove sessions on an LRU basis by having a finite limit, rather than just letting them be GC'd. The fact that so many sessions were collected in your runs indicates pretty severe memory usage.
(1) Is there any way to tweak this behavior? For
example can make the sessions live longer by using
some GC flags for the VM? Allocate more heap space, or cache fewer sessions.
(2) How about keeping regular references to all the
sessions in my application?That would save them from GC of course. But then you'll quickly discover that you really do need a finite limit.
(3) Is the behavior of the session cache or the inner
workings of the SSL API in general documented
somewhere?Only in the source code of JSSE, and that's only a property of Sun's JRE implementation. Session caching is not even a required feature, and J2ME implementations for example generally don't do it at all.

Executing writeObject() on Client Session

Hi Folks
I have a requirement wherein I want to run my CRUD[Create, Read, Update, Delete]operations from within a transaction.
The question is do I need a UnitOfWork as a MUST for update operations or can I invoke writeObject() on ClientSession itself! Because though ClientSesion class also exposes the writeObject() method, the documentation
says this:
The client session disables all database modification methods so that objects cannot be written or deleted. The client must obtain a unit of work from the client session to perform database modification.
Has anyone explored this before!
Thanks,
Prashant

You must use UOW with ClientSession, it is the only way to maintain the shared cache. If you need to use writeObject() you need to use a DatabaseSession.

UnitOfWork and server session cache

Hello,
seems like in some situations UoW does not update server session cache:
SessionManager manager = SessionManager.getManager();
Server server = (Server) manager.getDefaultSession();
Session client = server.acquireClientSession();
UnitOfWork unit = client.acquireUnitOfWork();
// stored procedure call preserves caching !
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("security.set_current_user");
call.addNamedArgumentValue("p_user", 123);
unit.executeNonSelectingCall(call);
// these objects should always be cached (if caching is enabled) !
List list = unit.readAllObjects(Naudotojas.class);
unit.commit();
client.release();
server.release();
The presented source code executes stored procedure and read query within singe transaction. Problem is that selected data is not cached. But if stored procedure call is removed, then records will be cached. Is it expected behaviour ? That workarounds could be applied to force caching ?

When the first modify call is performed in a UnitOfWork it then assumes that the transactional state of the database is transient and therefore and data read could be non-committed. At this point it is not safe to load the objects into the shared cache.
If you are attempting to make use of VPD security you should read up on the support offered in TopLink. It will give you additional call-backs for setting the user credentials.

SSL session cache memory consumption

Hello,
I am implementing a high availability application that uses SSL session caching. How much memory does it consume? I mean, is setting session cache size to unlimited a 'safe' option?
Thanks.

Not for a server, limit it to something. It's in the server's interest to keep sessions few and short-lived, but conversely it's in the client's interest to keep sessions many and long-lived.
A 'session' object contains the master secret and the current session key, and references to the peer certificate chain.

Client automatically cache the data got from cache server?

Hi expert,
I have 2 questions about the client local cache. Would you please help to give me some suggestion？
1. Will client automatically locally cache the data got from cache server the first time and automatically update the data in local cache when getting the same data from cache server again? I go through the API reference but cannot find any API to query the data currently cached in the local cache.
2. If client will automatically cache the data got from cache server. Is there any way for a client to get the data event that happens to its local cache, such as entry created in local cache, entry deleted from local cache and entry updated in local cache? In my opinion, when getting an entry from cache server the first time, the MapListener's entry create event should be triggered. When getting the same entry again, the entry update event should be triggered.
However, I have tried a client with replicated cache, a client with partitioned cache, an extend client with remote cache and a client with local cache(front cache part of near cache), the client (the NamedCache object has been set the MapListener) cannot get any event notification after getting data from cache server. By the way, my listener is OK since when putting data the entry create event and entry update event will be triggered.
Your suggestion is very appreciated. :)

Hi
If I were you I would read this http://download.oracle.com/docs/cd/E14526_01/coh.350/e14510/toc.htm
and particularly the section about Near Caching here http://download.oracle.com/docs/cd/E14526_01/coh.350/e14510/nearcache.htm#CDEFEAJG
which is what you are asking about in your question.
Near Caching is how Coherence stores data in the locally - which is the answetr to your first question. How Near Caching works is explained in the documentation.
Events, which you ask about in your second question are explained here http://download.oracle.com/docs/cd/E14526_01/coh.350/e14510/delivereventsjava.htm#CBBIIEFA
It might be that ContinuousQueryCache is closer to what you want. This is explained here http://download.oracle.com/docs/cd/E14526_01/coh.350/e14510/queryabledatafabric.htm#sthref38 A ContinuousQueryCache is like having a sub-set of the underlying cache on the local client which you can then listen to etc...

Possible to delete Offline Files content for a specific user from the Client Side Cache (CSC) ?.

Hello Everyone,
We would like to implement a script to delete the offline files in the Client Side Cache (CSC) for a nominated user (on Windows 7 x64 enterprise).
I am aware that;
1. We can use a registry value to flush the entire CNC cache (for all users) next time the machine reboots.
2. If we delete the user's local profile it appears that Windows 7 also removes their content from the local CSC.
However, we would like to just delete the CSC content for a particular nominated user without having to delete their local user profile.
In our environment we have many users that share workstations but only use them occasionally. We don't use roaming profile so we would like to retain all the users' local profiles but still delete the CSC content for any users that haven't
logged on in a week.
Any ideas or info would be appreciated !
Thanks, Makes

Hi,
I don't think this is possible.
If you want to achieve it via script, I suggest you post it in official script forum for more professional help:

451 kbytes for 30mn seems to be very low; someone has an idea about such low values ?
The WCS version is 7.0.172.0
thanks in advance

Thanks for the suggestion JKramer. I should have been more clear about having adjusted all volumes up in the settings screen. Assuming all sound options are located within the "Settings --> Sound & Display" screen, then yes, I have tried changing them. I have also tried changing the option to "use incoming call volume for notifications" under the "ringer volume" settings, after reading that someone had success in improving volume that way.
This issue is not a problem all of the time. It is only an issue when there is an elevated level of background noise, such as driving on the freeway, or having music or a movie playing in the room.
The phone is otherwise excellent! I live and commute in areas of very spotty reception (with all cell providers), and this phone will keep calls and not even have voices garble where my past two phones have consistently dropped calls in at least five problem locations. So far, everything else about it seems to work great!
Maybe some of these phones don't have this issue. Or, maybe the people who say they don't encounter the problem are lucky enough to live in relatively quite environments most of the time. In a quiet house or office, it is certainly loud enough. It just needs to have the option for increased volume when in noisy places. The issue is that its "max volume" settings are not as loud as with other phones.
Searching for something like "Droid X volume" will indeed show many people experiencing these same problems on various forums...
