Can I reuse session inf. on another PC?
I'm just curious about:
1. Can a session information be saved at some place like DB or a file?
2. And can it be re-created from the saved one?
I got an environment with 1-server and 2-PCs. Let's think about a scenario like following.
1. PC A connects to the server and a fresh new session should be established.
2. PC A logs in and the login information is saved on that session.
3. PC A or the server saves the session information at some place.
4. PC A disconnects with the server.
5. PC B connects to the server. If there is a session information has been saved, create a session with saved information.
So, a session for PC A has been moved to PC B and PC B can use the same session information with no need to re-login or something.
How can it be done? Is there any way to do this?
Wesjohnson,
It pretty much depends on what enviroment and development tool you are using. The simplest way would be to add it into your system CLASSPATH, but that's not really the preferred way of doing things. If you are using any IDE, it should allow you to add required libraries for your current project, and then these would be used in the compilation stage.
Or if you are using ANT to build your application, then the build.xml should define the classpath used for the <javac>-task somewhere.
Don't forget that you need to ship the libraries with your application as well, otherwise you'll be getting lots of NoClassDefFoundErrors at runtime.

Can I reuse Structure used in another report?
Hi
Is it possible to use a structure as used in a query for creating another query?
My new query will have mostly all the formulas used in that structure (but is based on different infoprovider)
If yes then what is the procedure for it?
Thanks
IshiHi,
Yes, that is a standard check.
Here are two work arounds:

Download content on one mac can i reuse for another?
Where is the downloaded content for the latest GB located?
can I reuse it?No I haven't tried that. What might that do?
It will download about 5 GB of additional content that has been previously purchased. You can continue working with GarageBand, while the download proceeds, and if you interrupt it, it will resume the next time you start GarageBand. -
How can i reuse a structure in the query designer in 3.5
Hi all,
we are using the version BW 3.5, now how can i reuse a structure made int he query designer, because i need it in another query, i did the structure and put it a technical name and save, help guysHI Richard,
Create a Structure in Rows/columns and save As it, then in the left Panel of the Query Designer you can see three Folders
1) Structures
2) Keyfigures
3) Dimensions
then Expand the structures Folder, there you can find your saved structure, Structures are 2 types
1) With Key figures
2) Without Key Figures
If you have the key figures in your saved structure, then you can find it in the subfolder of with Keyfigures, else in the other folder.
Now you can use this structure by draging in all the queries which are on the same InfoProvider (CUbe. MultiProvider)

How can I reuse the BC4J database connection?
How can I reuse the BC4J database connection?
I want to use the application module connection without opening another in a custom code. At this level I canât access de ADF code, thatâs why I canât get the DBConnection from the application module.
Now, I have a âdata-sources.xmlâ in my project and the application module is configured to access the database from this xml file.I found the solution in other Forum. I worked ok.
Here the code:
If the Connections-Navigator connection is DBConnection1, the corresponding datasource is jdbc/DBConnection1DS.
1. Create a JSP page.
2. In the web.xml of the JSP add
<resource-ref>
<res-ref-name>jdbc/DBConnection1DS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
3. In the JSP page obtain a connection with the datasource.
InitialContext initialContext = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)initialContext.lookup("java:comp/env/jdbc/DBConnection1DS");
java.sql.Connection conn = ds.getConnection(); -
How can i reuse same variables that i create using c:set var="index" /
hi all,
please some one helpme!!!!!!
how can i reuse same variable that i create using
<c:set var="index" value="${0}"/>
cause later in the program i use index to do some condition and based on that i increment ...
so for example if i say...
<c:if test="${index==0}">
<c:set var="index" value="${index+1}"/>
</c:if>
will it be like
if(index==0)
index++;
can i do like i did be4. if not what do i need to do to reuse. cause i use the variable atleast 5 time and its keep changing on diff condition level.Have you tried it?
It should work, provided you are on the same page.
The c:set tag creates the variable in pageScope by default.
If you forward to another JSP you need to set the scope to be "request" so that it is still available. -

Log Message:
Bug: 2780176 - Logging and logging out multiple times in LCDS can cause duplicate session detected errors.
QA: Yes
Doc: No
Checkintests: Pass
Details: When a logout was followed by an immediate login, sometimes the server would throw duplicate session detected errors. This was because when logout happened, a fire-and-forget disconnect message was sent to the server that established a new session, and if the subsequent login happened before disconnect ACK returned from the server, that would establish another session and hence the error. The fix is to insert a slight delay between disconnect and ResultEvent dispatching. This way, disconnect has a chance to return before a login is performed.

flex/sdk/trunk/frameworks/projects/rpc/src/mx/messaging/ChannelSet.asYou've got an incompatible Logitech driver and java was incompletely uninstalled.
You may have a problem with the Wacom driver.
I don't know if fixing those things will help.
There also a few window server errors, but I don't know if they are causal.
If you can note the time of the hangs, that might help narrow it down in the logs. -
Object locked in v$locked_object but can't find session/process blocking
Hi,
I am on database 10.2.0.5, windows x64.
A developer calls me and tells me there are locks on 3 tables, and the locks are not released.
So I run this to see which objects are locked by which session
select vlo.object_id, vlo.session_id, vlo.oracle_username, vlo.process
, DECODE(vlo.LOCKED_MODE, 0,'NONE', 1,'NULL', 2,'ROW SHARE', 3,'ROW EXCLUSIVE', 4,'SHARE', 5,'SHARE ROW EXCLUSIVE', 6,'EXCLUSIVE', NULL) LOCK_MODE
, do.owner, do.object_name, do.object_type
, vs.saddr, vs.serial#, vs.paddr, vs.username, vs.ownerid, vs.status, vs.server, vs.schemaname, vs.osuser, vs.machine, vs.program, vs.type, vs.logon_time, vs.last_call_et
, vs.blocking_session_status, vs.event#, vs.event, vs.wait_class#, vs.wait_class, vs.wait_time, vs.seconds_in_wait, vs.state
from v$locked_object vlo
inner join dba_objects do on (vlo.object_id = do.object_id)
left outer join v$session vs on (vlo.session_id = vs.sid)-----------
I get (after finding out my table locks come from SID 514)
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE

I run it again and I get something different, this time the lock is still there, but no session. select * from v$session where sid= 514 returns nothing.
I get
OBJECT_ID SESSION_ID ORACLE_USERNAME PROCESS LOCK_MODE OWNER OBJECT_NAME OBJECT_TYPE SADDR SERIAL# PADDR USERNAME OWNERID STATUS SERVER SCHEMANAME OSUSER MACHINE PROGRAM TYPE LOGON_TIME LAST_CALL_ET BLOCKING_SESSION_STATUS EVENT# EVENT WAIT_CLASS# WAIT_CLASS WAIT_TIME SECONDS_IN_WAIT STATE
373122 514 ROW EXCLUSIVE IRMFIN IC_PRODUCT_STATUS TABLE
373025 514 ROW EXCLUSIVE IRMFIN IC_BIN_DETAIL_STATUS TABLE
373055 514 ROW EXCLUSIVE IRMFIN IC_LOT_STATUS TABLE When I run the query later, I sometimes get another session, but the lock stays. It seems here, that I am catching the same SID on new sessions, but it is probably a different serial # than the original session locking the table rows.
I get nothing from
select * from dba_waiters;
select * from dba_blockers;
Now why are those 3 tables row locked on some rows and I can't find the session responsible? The developer tells me his application crashed and the rows are locked since.
So far ( keep in mind I am not a locking expert) the only way I found to release the locks is a DB bounce, its a test DB so no biggy.
Is this a bug? Am I missing something?
This is the second time this has happened. How can I solve this issue?
Best wishes to all.Thank you for your reply.
I do not think I can kill the session (514) it does not exist, even though v$locked_object reports tables are locked by session 514
see below
select * from v$locked_object

JMStudio Error "Can not create session manager"
Hi,
I'm trying to transmit an mpg file through a simple pc to pc network, using the transmission wizard in the JMStudio, and everytime it causes a "can not create session manager" error, even when I try to transmit .mp3 file
I'm using an ip like 100.100.0.1 for the sender machine, and 100.100.0.2 for the receiver machine, and I don't know where is the problem
thanks in advanceUm,maybe the port that you use for transmission is already occupied.
Make sure that you are not using JMStudio to transmit streams while trying to receive streams from the same port. -
How can I backup my iPad to another iPad backup I have on my same iCloud account. The old one is totally gone. Both backups are listed on my iCloud account. So is there any way I can backup the one I have now to the other one. I really just want the pictures that are in the old backup. I have tried resetting and erasing all settings and data on the one I still have, but when I go to restore by iCloud; it only gives me the choice of restoring the same iPad. Then in iCloud>storage>backup, I'm still not able to choose which backup to backup to. I've even tried deleting the backup to the iPad I still have, then resetting all setting and data on the iPad, hoping that in resetting up the iPad it would give me the option to backup to my old iPad. But it doesn't. It still has memory of the backup of my newer iPad.
I JUST WANT THE PICTURES!!!
Thank you!!!
iPad (3rd gen) Wi-Fi + Cellular, iOS 6.1.3, iCloud BackupYou now need to get your pictures back! The similar to you, after I updated my iPad Mini, I can't get my some files on device.

If I imported a CD into my iTunes library from one computer how can I listen to it from another computer? I imported music from a CD into my compter at work and when I got home and went to my iTunes account none of the songs were in my library. I also noticed that on my Work computer there were a couple songs that I had to click on the little 'cloud' icon before I could listen to them (these were not songs I imported they were songs that were already in my library).
