DPS6.3 modify default connection handler?
While making some changes in a dps through the dscc I edited the default connection handler and added two connection policies. I have now lost access to the dps through the dscc possibly because of the policies added.How do I fix the default connection handler? Is there a dpconf command to read it, and delete the policies?
Edited by: Xoth on Jun 11, 2009 12:38 PM
FIXED. I figured it out. Looking at reference manual instead of admin where the dpconf commands are.
dpconf get-connection-handler-prop -h host -p port "default connection handler"
dpconf set-connection-handler-prop -h host -p port "default connection handler" request-filtering-policy:no-filtering
dpconf set-connection-handler-prop -h host -p port "default connection handler" resource-limits-policy:no-limits
Dummy post to increase the reply count. Sorry for the noise.

LDAP Proxy fails to assign custom connection handler
Hi,
I've setup some custom connection handlers, and my proxy server is behaving randomly.
I mean that sometimes it assigns the new handler sometimes not. This randomness occurs
if I delete the handler and create it again with the same configuration options.
I tried restarting the server as well as upgrading to 6.3.1 (Linux/Centos) without any luck.
Now the server does not assign the high priority custom handler when I connect on the SSL port (1636)
but it does assign it if i connect on the NON-SSL port (1389)
This is is my configuration:
dpconf list-connection-handlers -v -p 1636
anonymous true 5
domain2.example.com true 3
default connection handler true 100
directory services administrators true 1
domain1.example.com true 1
schema false 6

As you see the connection is routed through default connection handler.
This happens sometimes even If I put the client IP in the criteria, without the bind criteria.
I'm a bit comfused. I've also tried to change the priorities but no luck again.
The funny thing is that If I connect through the NON-SSL port on the proxy the connection
is routed through the domain1.example.com connection handler...
[07/Apr/2009:19:51:32 +0300] - PROFILE - INFO - conn=37 assigned to connection handler cn=domain1.example.com,cn=connection handlers,cn=config
any comment on this would be appreciated
regards,
GiannisTalking about randomness, I've deleted the connection handlers,
deleted the default data views, deleted the default data pool, enabled manual routing.
recreated the connection handlers and now it works.
The handlers are the same as before. Same criteria...
Don't get it but there must be something fishy going on there...
any way, what I'm trying to do is a setup like
"Data Views That Route Requests When a List of Subtrees Is Stored on Multiple, Data-Equivalent Data Sources"
http://docs.sun.com/app/docs/doc/820-2763/gbwva?a=view
where requests with the parent domain as base would work as well.
domain1.example.com
domain2.example.com
example.com (includes both)
if I have something new I will post

A stale Connection Factory or Connection Handle may be used in SOA 11g
Hi all,
I am working on a outbound process from oracle apps to BPEL. I am using SOA 11.1.1.3 version. I have created connection pool in admin server.
But BPEL does not pick the messages from ecx_outqueue present in apps.
Also when i update the Aqadapter in the admin server i get the following message
Selected Deployments were updated.
You must also activate the pending changes to commit this, and other updates, to the active system.

Can anyone provide some inputs on this?Hi Anuj,
I have followed the following steps mentioned in the metalink ID 1235943.1 but still it is throwing the same error.
1.Log on to your Admin console and navigate to Domain -> Deployments -> <adapter name> -> Configuration Tab -> Outbound Connection Pools Tab -> Under Groups and Instances expand the javax.resource.cci.ConnectionFactory
2.Locate and select the adapter JNDI and click on the Connection Pool Tab.
3.Please check to see if Shrinking is enabled. If not, please enable it.
4.Please check the value for Shrink Frequency Seconds. The default for some connection pools is as high as 900 seconds. Please reset this to 120 seconds or less.
5.Activate your changes.
6.If this does not improve the situation, please also try increasing the max size of your connection pool.
Please advice if any other solution is there.
Thanks,

SAP workflow not published / not reaching default outbound handler
Hi,
At Velocity event (october) we had a SAP ERP workflow configured for publishing to SharePoint; after triggering workflow instances, an XML payload document was successfully published to SharePoint.
Now, in the same environment; without changes on Duet Enterprise config level, publishing of task changes of that same workflow no longer publishes into SharePoint.
We executed the report jobs OSP_DELTA and OSP_FULL to make sure that the sync from SAP to SharePoint would be done / task changes are notified. The SAP workflows are delivered into the SAP inbox; but not published to SharePoint.
We added a breakpoint (internal + external) in the default outbound handler S_OSP_WF_PAT_DEFAULT_CH_OB; it is not invoked when we reach the workflow decision step that is published.
We inspected the SCL Logs, but didn't find any relevant log entries.
Any clue what can be wrong here; where to start with the problem analysis?
Best regards, William.Hi Holger,
The error 'Users not maintained...' appears to be caused due lack of SAP permissions of the SAP account that is executing the report S_OSP_WF_ITEM_SELECTION; with another account we succesfully pass the 'GetNotifications' calls within that report; and actually now do get into the default outbound handler.
But still no task document published into SharePoint; the default outboundhandler faults on Send Action item; error details:

How can I get the handle to database connection used by my BC4J
application.
It should be something like this
Connection conn = .....
I dont want to create a new connection using DriverManager.
I have created connection using Application module class.
I want to use the same connection.
Thanks
ChandarThere is a default connection that you can use. Try using this:
Connection conn = ( new oracle.jdbc.driver.OracleDriver
()).defaultConnection();
Hope it helps,

New error with upgrade jboss/tomcat: "Connection handle has been closed and is unusable"
Hi,
This error suddenly appeared when we upgraded from jboss3/tomcat5.0 to jboss4.2/tomcat5.5.
here's the usecase:
1) User clicks on report link
2) Crystal reports web componnent displays screen to fill in report parameters.
3) user enters parameters and clicks submit
4) System throws Exception
The same reports worked fine with jboss 3.2.6/tomcat 5.0. We haven't touched anything in this realm.
Log Excerpt:
09:42:18,842 INFO [datasource] Openning rowset
09:42:18,904 ERROR [reportdefinition] com.crystaldecisions.reports.queryengine.driverImpl.m: JDBC Error: Connection handle has been closed and is unusable
09:42:18,905 ERROR [datasource] Failed to open rowset: the query failed to open rowset
com.crystaldecisions.reports.reportdefinition.datainterface.g: JDBC Error: Connection handle has been closed and is unusable
at com.crystaldecisions.reports.reportdefinition.datainterface.d.a(Unknown Source)
To try to narrow down the problem, I've updated the jdbc configuration to
<track-statements>true</track-statements>
here's a recap:
This Boolean element specifies whether to check for unclosed statements when a connection is returned to the pool. If it is true, a warning message is issued for each unclosed statement. If the log4j category org.jboss.resource.adapter.jdbc.WrappedConnection has trace level enabled, a stack trace of the connection close call is logged as well. This is a debug feature that can be turned off in production.
Interestingly enough, this error appears slightly upstream:

So the question arises:
1) Is the jboss datasource overly/aggressively closing result sets?
2) or is there a coding error in CRXIR2?

OK. I found the problem along with a workaround.
</p>
<p>
<strong>The problem:</strong>
</p>
<p>
a programming practice clashes with a new jboss 'safety check'.
</p>
<p>
<strong>Programming practice:</strong>
</p>
<p>
crystal reports gets a database connection in one jsp page, then tries to use it on another jsp/servlet
</p>
<p>
<strong>Jboss safety check:</strong>
Jboss/tomcat new comes configured out-of-the-box with a 'cached connection
manager', which
</p>
<p>
"Check[s] for unclosed connections and transaction terminated checks in servlets/jsps."
</p>
<p>
<strong> Summary</strong>
</p>
<p>
In short, if a servlet/jsp ends and it leaves a database connection open, Jboss will automatically close it.
</p>
<p>
</p>
<p>
<strong>Workaround:</strong><br />
Comment out two entries in these two files:
</p>
<p>
1) conf/jboss4/pe/deploy/jboss-web.deployer/server.xml
</p>
<p>
2) conf/jboss4/pe/deploy/jboss-web.deployer/META-INF/jboss-service.xml
</p>
<p>
The two entries:
</p>
<p>
</p>
<p>
1)
</p>
<p>
<Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve"<br />
cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"<br />
transactionManagerObjectName="jboss:service=TransactionManager" /><br />
</p>
<p>
2)
</p>
<p>
<depends>jboss.jca:service=CachedConnectionManager</depends><br />
</p>
<p>
</p>
<p>
<strong>Comments on the workaround</strong>
</p>
<p>
The 'cached connection manager' basically makes sure that the application cleans up after bad programmers. It seems most helpful in development, load testing, or trouble shooting.
</p>
<p>
In production, you can likely comment them out with minimal
impact on the application.

Windows RDS - configuring a default connection & desktop
I'm looking at remote desktop options and used terminal services in the past. I'm configuring remote desktop services on a Windows 2008 R2 server. The goal is
to allow users to go to a web page, pull up a remote desktop and access apps & server shares inside the network.
I have it installed, and am able to get a connection using \\server\rdweb. However, that takes me to the RDS default connection page. If I click on remote desktop it asks what computer I want to connect
to.
What I want to do is configure this or another web page to automatically connect to a default profile I've configured with various apps, or to create a new profile based on the user's login name like any PC
does when you login with a new user ID.
I'm sure it's in the documentation somewhere, I haven't run across it yet.Hi,
Thanks for your posting in Windows Server Forum.
As per your comment, I can say that you can try to change the login web page of RD web where you can place the default domain and user name for that user.
You can make changes on login.aspx file on “%windir%\Web\RDWeb\Pages\<The Language of Your Location>\”path as below:
Change the original code section:
<input id=”DomainUserName” name=”DomainUserName” type=”text” class=”textInputField” runat=”server” size=”25” autocomplete=”off” />
to be:
<input id=”DomainUserName” name=”DomainUserName” type=”text” class=”textInputField” runat=”server” size=”25” autocomplete=”off”
value=”domainname\” />
Please refer below thread for more information.

Setting up default connection for accessing emails...
I had a quick look and found similar problems on here, but none that I thought were the same.
I've been able to set up Gmail to be received through my 'Messaging' on my N96. Turns out its quite a handy function. Also figured out that you can get it to automatically check you mail at regular intervals. I want to use this, but I don't want to have to select the connection every time the phone wants to check for new mail. So I need to set up a preferred connection. That's no problem...
The problem occurs when I try to select my WLAN as default. However, every time I select it, the phone freezes up. Not completely, as I can change programs and even exit the messaging settings via the hang up key, but if I do that, it doesn't make any changes.
I have deleted and restored the WLAN connection, I have accessed my inbox manually, so it isn't a problem on Google's end, and I have checked the various connection options to no avail.
So, does anyone know why it my phone would freeze when trying to set up my WLAN connection as the default connection for accessing my e-mails? Any questions about my situation, just ask and I will gladly supply whatever you ask for.
Regards,
Jarvis

E51 default connections access with WLAN - how ?
Hi.
I just bought a lovely e51, and I love it, but after playing with it for 2 days, I cant seem to set the default connections to WLAN.
For instance, when I click on the WLAN from the front menu, it offers to browse using wifi, thats great.
But if I click on the Web icon, or the Nokia maps, or the Download stuff, it takes me to "Data Package" which I dont want to use, when I have a WLAN at home.
I understand that the WLAN wont be able to "download" every type of contents (like the Radio?) but surely it should work with the Web & Downloads?
Any hint most welcome.
NikHi,
Open browser, click on left soft button, options, scroll to settings,general,access point and set to always ask.
This way you can select each time you log on to browser.
Or tools, settings, connection, packet data, access point and fil in you settings.
Better to have choice at start up that way if you are not in wi fi area you can just select high speed data.
Cheers. -
How to change the default connection
I've to change programmatically the default connection of the report (6i).
I thought to use somenthing like LOGOUT/LOGIN (FORMS6i) in the BeforeReport trigger, but I don't find any valid solution yet.
Thanks in advance,
RaffaeleThe reports are developed with Report Builder 6.0.8.8.3.
The server is configurated: Oracle HTTP Server/1.3.22 (Win32)
mod_plsql/9.0.2.0.0 DAV/1.0.2 (OraDAV enabled)
mod_oc4j/3.0 mod_ossl/9.0.2.0.0 mod_fastcgi/2.2.10 mod_perl/1.26
From my application I call iexplore and set the url like:
http://<myserver>/dev60cgi/rwcgi60.exe?MY_REPORT+<jobid>
In cgicmd.dat I defined:
MY_REPORT: report=D:\report_path\theREPORT.rep
userid=def_user/pwd@the_db
server=my_repserver...
In the report, in the BEFORE_REPORT or in BEFORE_PARAMETER_FORM trigger I would like to make a query to a table of def_user with the job_id filter and get the job specific connection info.
Then, I've to re-connect to the new user where the tables of the report's data model a re defined.
Our database is structured with a single user for general data, included the info to address the other schema, and more specific users (~100) for job data.
I've used the tecnique in Forms, but I can't replicate it in Reports.
Thank you for any suggestions.

RajHi,
The error message "Could not create JCOClientConnection for logical System" is only triggered when the WebDynpro application is requesting more JCO connections than the number of JCOs allocated for this application.
I suggest to carefully go through the documents below in order to properly configure your JCOs. If necessary, remove them and recreate in the correct way:
JCo Quick Summary
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/85a483cb-0d01-0010-2990-c5168f01ce8a
How to Configure the JCo Destination Settings
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3103eb90-0201-0010-71af-be6f4a6f61d1
You will have to calculate the maximum number of JCo connections to each application based on Models and users.

hi all,
In the jdbcpds.conf file, it is mentioned that we can write our own connection handling class which extends the provided JDBCConnectionHandling class
What i tried after looking at the methods of connection handler is something like this
class myJDBCConnectionHandling extends JDBCConnectionHandling
protected void parseConnectInfo(String s, JDBCConnectDialog jdbcconnectdialog, Plugin plugin)
throws Exception
String dbUrl = null;
dbUrl = "<user>/<pwd>@<remotedatabase>";
super.parseConnectInfo(dbUrl, jdbcconnectdialog, plugin);
Is there anything else that needs to be done
because this is throwing an error
JDBCPDS-62008 : Failed to connect to the datasource null
Invalid arguments in the call
Can anybody correct me
Of course my main purpose of trying this is to have something like a logical name given to the P_JDBCPDS parameter which can be mapped to the actual database url using JNDI lookup.
what i was expecting was, the string when passed to the connection handler, i can add the code to lookup the name in my own connection handler and leave the rest to the provided JDBCConnectionHandling class
Am i going in right direction or not
Or if anybody has any other solution you are welcome to suggest
Any sort of help is greatly appreciated
Thanks in advance
Ramakrishnahi,
One more thing i forgot to mention was that i am not too concerned about this lookup in reports builder
I need when this is running on the server
thanks & regards
