-t2cGetCharSet error when using thick client with 1.0.0.15.57

I think I have found a bug in 1.0.0.15 related to accessing a database using the thick client. I have tested this with 1.0.0.14 release of SQLDeveloper and that version DOES work OK.
Simply put, I try connecting to a database using the 10g Client on Windows XP and I get "Failure: -t2cGetCharSet" error when running 1.0.0.15.57. I must use 10g thick client so that I can use encyption between the client and the database. 9i thick client doesn't work between Windows and Linux when using encryption. Also, instant client isn't an option; it doesn't support Advanced Security Option (encryption).
I DID test without encryption enabled to eliminate that as a possible cause and the results were the same.
If need be, I could back down to 1.0.0.14, but I would prefer not to.

Unknown namespace prefix Error - when using custom Aliases with RDF aliases

I am getting unknown namespace prefix error when I use custome SEM_ALIAS with rdf SEM_ALIAS. It seems once you specify custom SEM_ALIAS, the default rdf alias is not recognized. Following are the details of queries
I have a sem_Model "test" which has "event" as a class and "Merger" as a sub-class of event, with "acquiringorg" as a property having the domain "org". "Org" is also defined as a class with the literal attribute "hasname". I have added one instance of "merger" class with appropriate values for "acquiringorg" property. There is one instance or "Org" as well for reference in the instance above.
the following query(return all objects having property "acquiringorg" and its .e. "hasName" attribute for the object) runs fine and returns appropriate resultset
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
However when I want to add another criteria i.e. show me events of type merger(?x rdf:type :Merger) , the query fails with the "unknown namespace prefix error" as above
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x rdf:type :Merger)(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
specifying "rdf" ALIAS explicitly also does not work
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x rdf:type :Merger)(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(_SEM_ALIAS('rdf', 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'),_
SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
I am unable to figure out why default namespace i.e. rdf is returning this error
Stuck at this point badly!!Any pointers would be useful!!

Full error details are as below

Error when using Analytic view with Input Parameters

Hi,
I am trying to create an info space based on my Analytic view which has input parameters. The infospace is validated and indexed without any issue. However when I ran the view, I get an error (50011) as it is unable to fetch any results. I tried using an infospace based on Calculation view with input parameters and the explorer view works without any issue.
Has anyone faced similar issues?
We are using HANA SP 6 rev 67 and BI 4.0 SP 4.
Also is there a way to enable input prompts for the users when they refresh the BO Explorer view? If not currently available is there any work around ?
Thanks

Hello George,
I don't have any personalization set on the info space. Also I am using mapped Account in BI to connect to HANA. The confusing part is that it is able to validate the infospace with the input parameters and index it. However query does not return any results. I even tried running the same query which explorer sends to HANA in the SQL editor and there too the same results,the query does not return anything. The model does return data when I do a data preview and if accessed from other tools like AAO.
Also when I use SSO connection to HANA, indexing of the infospace fails. Where can I see the error log?
Thanks,

There is some java bug that is causing some problems if you are using 9.2.0.3. Here is some information:
Workaround for bug 2755842:
Event 10499 can be set (any non-zero level) to revert to the old behaviour.
==================================================
Setting the EVENT 10499
=======================
Check if the database server is using a server parameter (spfile) a parameter (init.ora) file.
From sqlplus, connect as sysdba and execute the command:
show parameters spfile
If the value is NULL or empty, then spfile is NOT enabled and init.ora is used.
1) If SPFILE is used:
SQL> show parameters spfile
NAME TYPE VALUE
spfile string
%ORACLE_HOME%\DATABASE\SPFILE%ORACLE_SID%.ORA
a) Using sqlplus logon as sysdba
b) Execute: alter system set event="10499 trace name context forever,level 4" scope=spfile
sid='*';
c) shutdown
d) startup the database
2) If INIT.ORA is used:
a) In the init<SID>.ora file, add the parameter event="10499 trace name context forever,level 4"
b) Stop and start the database
Hope this is it.

Certificate Error when using pub services with IE7

hi,
IE 7 has changed the way certificates were handled when
compared to IE 6. In IE 6, the user gets an option to view the
certificate before proceeding to view the site. In the process the
user can import the certificate into the browsers trust store.
Since CPS is deployed with a self signed certificate, in IE 7
we get a certificate error.
There is currently no workaround for the same, except to
deploy cps war file on an application server that has a certificate
signed by a signing authority

XSL Errors When Using AQ Adapter with EBS Business Events

I am triggering a BPEL process with an Oracle EBS Business Event. After receiving the event, I am trying to perform an XSL transformation to extract parameters from the event. However, I keep getting XSL errors because the BE field ERROR_SUBSCRIPTION comes in containing invalid XML characters (#).
It seems that BPEL or EBS do not properly escape the XML input. Is that a bug, or is there a way to work around this. I know I could filter the XML input in some way, but that seems likely to be more brittle to any future changes to the EBS BE message types.

Adding to the above post, how will the PL/SQL program which triggers the Business Event ensure that the complete data is enqueued in the queue in form of XML?
What will be the additional logic to send complete data in the XML format?

GET t2cGetCharSet error when connecting to AIX5L 10.1.0.4 with AWM2

Hello,
I'm receiving a "t2cGetCharSet" error when I try to connect to a AIX5l 10.1.0.4 database with the new AWM2 workspace manager. I can successfully connect to a 10.1.0.4 database on linux with the same workspace manager. Any ideas?
Thanks,
Carl

This is a problem with your PATH. You need to adjust it before running AWM so that the proper versions of the dependent libraries are picked up. If you have a 10.1.0.4 ORACLE_HOME on your system, point it there.
Or, you can just use the thin client connection by specifying machine:port:sid.

Jvm startup fails with error when using large -Xmx value

I'm running JDK 1.6.0_02-b05 on RHEL5 server. I'm getting error when starting the JVM with large -Xmx value. The host has ample memory to succeed yet it fails. I see this error when I'm starting tomcat with a bunch of options but found that it can be easily reproduced by starting the JVM with -Xmx2048M and -version. So it's this boiled down test case that I've been examining more closely.

Any ideas?

These are the relevant java options we are using:
-server -XX:-OmitStackTraceInFastThrow -XX:+PrintClassHistogram -XX:+UseLargePages -Xms6g -Xmx6g -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=128m -XX:MaxPermSize=192m -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+ExplicitGCInvokesConcurrent -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.awt.headless=true
This is a web application that is very dynamic and uses lots of database calls to build pages. We use a large clustered cache to reduce trips to the database. So being able to acces lots of memory is important to our application.
I'll explain some of the more uncommon options:
We use the Concurrent Garbage collector to reduce stop the world GC's. Here are the CMS options:
-XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled An explicit coded GC invokes the Concurrent GC instead of the stop the world GC.
-XX:+ExplicitGCInvokesConcurrentThe default PermSizes where not large enough for our application. So we increased them.
-XX:PermSize=128m
-XX:MaxPermSize=192mWe had some exceptions that were omitting their stack traces. This options fixes that problem:
-XX:-OmitStackTraceInFastThrowWe approximate between 10% to 20% performance improvement with Large Page support. This is an advance feature.
-XX:+UseLargePagesUseLargePages requires OS level configuration as well. In SUSE10 we configured the OS's hugepages by executing
echo "vm.nr_hugepages = 3172" >> /etc/sysctl.confand then rebooting. kernel.shmmax may also need to be modified. If you use Large Page be sure to google for complete instructions.
When we transitioned to 64bit we transitioned from much slower systems having 4GB of ram to much faster machines with 8GB of ram, so I can't answer the question of degraded performance, however with our application, the bigger our cache the better our performance, so if 64bit is slower we more than make up for it being able to access more memory. I bet the performance difference depends on the applications. You should do your own profiling.
You can run both the 32bit version and the 64bit version on most 64bit OSes. So if there is a significant difference run the version you need for the application. For example if you need the memory use the 64bit version if you don't then use the 32bit version.

Checkintests pass
Modified Paths:
    blazeds/trunk/modules/core/src/flex/messaging/endpoints/BaseHTTPEndpoint.java

For our profect I think this issue was caused as follows:
Believing that remoting was full asynchronous we fired a 2 or 3 remote calls to the server at the same time ( within the same function ) - usually when the users goes to a new section of the app.
This seemed to trigger the duplicate http session error since according to http://blogs.adobe.com/lin/2011/05/duplication-session-error.html two remote calls arriving before a session is created will cause 2 sessions to be created.
Our current solution ( too early to say it works ) is to daisy chain the multiple calls together .
Also there seemed to be an issue where mobile apps that never quit ( thanks Apple! ) caused the error when activated after a few hours.
I guess the session expires on the server and the error above occurs on activation.
So the mobile apps now ping the server with a remote call when activated after sleeping for more than one hour.
All duplicate http errors are silently caught and reported.
Fingers crossed we won't get any more!

Intermittent error when using the Disco Viewer client

Hi, I have a user receiving the following intermittent error when using the Discoverer Viewer client:
“The application encountered an invalid state.
- Discoverer Beans XML Exception. Method: findNode Class: XMLUtils Error: Cannot find parent node. Parent element does not exist in XML document, looking for database_account/eul
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.”
Any idea what this might be? Any help or direction would be very much appreciated! Thank you!

Hello
Is this related to a single machine or common to a single report or is it purely random?
I did a search on your behalf and came up with nothing related to this error. You may therefore need to raise the problem with Oracle Support.
Just out of curiosity which version of Discoverer are you using?

Error when using PPR in the OA page developed.

HI,
We are encountering an error when using PPR for the custom OA page being developed. I am using JDeveloper version 9.0.3.5(Build 1437) and Oracle Applications version 11.5.10.CU2. The scenario we are using PPR and the steps to reproduce the issue is mentioned below,
Scenario:
1) PPR is enabled for a custom OA page that is developed.
2) The PPR is being used to enable or disable a particular field based on the
selection of a value in a poplist in the same OA Page.
Error replication steps:
1) The user enters a value in the primary mandatory field which has to have
unique value.
2) The user selects a value from the poplist of a field which has PPR associated.
3) The user enters data in all other mandatory fields in the OA page except one
and tries to save the form and is shown a error message saying that all
mandatory fields are not entered(This is correct). Now the page gets
automatically refreshed and so the entered values are wiped off.
4) Now if the user again enters a value in the primary mandatory field (as in
step1) and if that value happens to be already existing value and then select
a value from the poplist which has PPR enabled then immediately the error
"Please enter a unique value" is entered, though we did not save the record.
The unique record validation would happen only at the time of saving the
record as per out business logic.
5) But if in Step 4 if i had entered a unique value again then the above said error
does not happen. There are few more similar kind of issues happening in the
same page because PPR is enabled.
Please note that this issue happens only when the page is deployed in a oracle
applications instance and not in JDeveloper.
Would this issue because of some cacheing problem? If Yes then how do we resolve it? Or would it be some other problem caused by our internal coding.
Any inputs for resolving this issue would be highly appreciated.
Thanks, Raja.

What works in Jdeveloper should work when deployed in iAS as well.
And PPR is an old feature given quite enough time to mature, so before we suspect OA we should investigate the code. What I do not understand is how the page refreshes in Step 3 and why does the user have to re-enter the fields just because he missed entering one mandatory field the last time.
Mandatory field validations are client validations set by making the fields 'Required'. You obviously have client validations turned off on your PPR, otherwise you would be stuck with a javascript popup on PPR. The only way you can get the "Please enter unique..." error on PPR is Server Validation. So where have you placed this validation? If it is not in the EO, is it in the AM? And are you unconditionally calling the AM validation method in your processFormRequest? The PPR will also go through processFormRequest so I hope the PPR event is in a different if-else block.
