ConnectionPool config on MacOS X using Oracle

I'm running WebLogic 7.x on MacOS X 10.2.1 with Oracle 9.2.x. I'm
trying to configure a ConnectionPool to use the type 2 driver that
comes with Oracle. I've tried multiple variations of driver name (ie.
oracle.jdbc.pool.OracleDataSource, oracle.jdbc.driver.OracleDriver,
etc) and I always end up with <Error> <JDBC> <001060> <Cannot startup
connection pool "PblsConnectionPool" java.sql.SQLException: No
suitable driver>.
For the URL, I've tried jdbc:oracle:thin@... and jdbc:oracle:oci@...
I've added the Oracle lib directories and classes12.jar to the
PRE_CLASSPATH when starting WebLogic.
Does anyone know what driver/URL combination will work with a normal
connection pool and/or an XA connection pool?
Thanks,
Craig

If you use oracle thin driver for creating pool you should use:
DriverName="oracle.jdbc.driver.OracleDriver"
URL=jdbc:oracle:thin:@databasename:1521:machinename"
And make sure you have classes12.zip in your classpath
If you want to use oracle oci driver:
DriverNAme="oracle.jdbc.driver.OracleDriver"
url = "jdbc:oracle:oci8:@machinename"
Also, make sure you have classes12.zip in classpath and ocijdbc8.dll in
path.
Thanks,
Mitesh

Compiling Apache 1.3.9 & PHP 3.0.12 to use Oracle 8.1.5 on SuSe 6.2

Hi!
I am trying to compile the above packets but am running into massive problems.
PHP3 compiles well, if i try to use the "normal" static module for Apache, but the Apache configure script says that it needs an ANSI C compiler and stops.
I am using GCC 2.7.2.3 with the bugfixes from SuSe.
Since that did not work I tried the configuration as a Dynamic Module. The Apache "Readme.config" explains two ways to do so, but the first has the same problem with GCC and the second (via APXS) compiles Apache without problems, but PHP3 wont compile since it does not find a library. The exact error is: "/usr/i486-linux/bin/ld: cannot open -lclntsh: No such file or directory"
I found a libclntsh.so.8.0 in the oracle/lib directory, but since i fumbled around with this library (i tried ln -s libclntsh.so.8.0 libclntsh.so) sqlplus says libclntsh.so.8.0: cannot find file data: no such file or directory (even now that the link is deleted again).
And PHP still wont compile. Any ideas would be welcome.
P.S.: Is it normal that Oracle has to be told NOT to create a database during install, TO create a database???
We worked for 3 days on the Oracle installation and that was the only way to install Oracle without errors.
thx

OracleAS - NULL ProviderSession after 15 minutes (Using Oracle PDK Portlet)

We have recently deployed an oracle pdk portlet java application (developed in JDeveloper 10.1.2.1) to an OC4J on a server running OracleAS 10g (9.0.4).
We are currently facing issues where our ProviderSession becomes null after 15 minutes.
In our jsp's we implement the following:
PortletRenderRequest pReq = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
ProviderUser pUser = pReq.getUser();
ProviderSession pSession = pUser.getSession(false); In our provider.xml file within our JDeveloper project/portlet we have set the following tag: <session>true</session>. In the provider itself, under the User/Session Information section, we have selected the User option, set the Login Frequency to Once Per Session and checked the box labeled 'Require portal user specific session information'.
In our web.xml file within our JDeveloper project/portlet we have set the following tag: <session-config><session-timeout>35</session-timeout></session-config>
As long as we stay within our portlet we don't seem to lose our ProviderSession, but after 15 minutes, if we try to access the portal page (to switch the language on the page for instance) the ProviderSession is null. This operation always works when we are under this 15 minute limit.
We have tried to change opmn.xml (increasing OC4J start timeout from 900 seconds to 1200 seconds),
modplsql conf (PlsqlIdleSessionCleanupInterval, changed from 15 to 30 minutes) and we have also tried disabling the Global Inactivity Timeout variables, but no luck as of yet.
Any help would be much appreciated !
Thanks

HI
i am also facing same problem with session but in simple portlet with ajax implementation.
i am setting session in portlet jsp with following code using oracle application server portal 10g.
(here portlet jsp means which is included from portlet.)
session.setAttribute("map",map);(here session is implicit object )
i want to call ajax jsp from portlet jsp with below code.(i.e setting session in portlet jsp and accessing in ajax jsp)
var url = "<%=renderRequest.getContextPath()%>/AjaxProcessRequest.jsp?q=" + random;
var pars = '&namespace=<portlet:namespace/>' +'&imagesPath=' + '<%=imagesPath%>';
var myAjax = new Ajax.Updater(
{success: 'emailbody'},
url,
method: 'get',
parameters: pars,
onFailure: reportError,
evalScripts: true
i am accessing map object from session in my AjaxProcessRequest.jsp as shown in below code.
Map map=(Map)session.getAttribute("map"); (here session is implicit object )
here map object is getting null from session.
Please help on this if u know about this session.

Image not displaying in pdf report using XSL-FO and using Oracle 11g databa

Good Afternoon,
I have created over 15 reports using XSL-fo, with the following syntax to display an image on the pdf:
fo:block margin-left="0.24cm" margin-right="0.27cm" margin-top="0.0cm" ><fo:external-graphic content-width="scale-to-fit" content-height="scale-to-fit" width="1.73cm" height="1.57cm" >
<xsl:attribute name="src">'url("http://readiness:7780/i/marforcom_symbol_rpts.gif")'</xsl:attribute></fo:external-graphic>
</fo:block>
This syntax works fine when using Oracle 10g, now my database has been upgraded to 11g and my image no longer displays in the reports. I have already upload the image into the database as a workspace image.
I have tried to point the image @ the image by using url(#WORKSPACE_IMAGE#marforcom_symbol_rpts.gif)
or <img src ="#IMAGE_PREFIX#marforcom_symbol_rpts.gif")
and it still doesn't work.
I have searched this forum trying to come up with a solution that will fix my problem and am unable to.
Current config: Oracle 11g, using pl/sql gateway.
I need to know how to point the xsl-fo file to the database, where the image now resides.
Thanks,
Mary

Hi,
I think you need load images to database XDB virtual directory /i/ and then use #IMAGE_PREFIX# substitution.
This might help to access /i/
http://www.apex-blog.com/oracle-apex/accessing-i-using-ftp-170.html
Or use this to load images

How to set file permission using Oracle FTP Adapter

Hi,
I am using Oracle SOA Suite 11.1.1.4. I am trying to put a file using Oracle FTP adapter on unix box. The file that gets written to target system has file permission as RW/R/R. But this is a legacy system, and for them to consume this file - they expect the file permission to be RW/RW/R.
They have set the .profile with the required permissions for the ftp user account that we are using. But still when my BPEL process writes a file to unix box through ftp adapter, the file permission is RW/R/R.
Is there any way to control file permissions while writing files using ftp adapter? Any help would be highly appreciated.

907597 wrote:
But these setting needs to be done on unix server. Yes, that's the way to go... There's no config for that on FtpAdapter as far as I know...
This setting will enable the same configurations for all other ftp accounts on the server, which doesnt sound correct. Any other way of doing this? Or can this be done only for one ftp account?You have to check if your ftp server is capable of having different umask for different ftp users... I believe most do not...

Queue using OracleAS JMS

hi , we have developed an application where we have a queue in websphere MQ and the application server used is oracle 10g . Now instead of using the websphereMQ or any other third party software , can we create a a queue and queue manager(MQ terminology ) in the oracle application server. We have created the queue destination and the connection factory in the oarcle , but how actully we have to create a queue and queue manger or is it not necessary to make one or is there any other way around, and we are trying for OEMS JMS In-Memory and File-Based Persistence , and hopefully the xml files are in right place i was refering to http://download-east.oracle.com/docs/cd/B25221_04/web.1013/b14427/jms.htm#sthref141
for the development

That's the right doc, you should create your destination and connection factory in jms.xml which is in j2ee/home/config directory.

Using Oracle Forms

Ok I'm a beginner at this! I plan to use Oracle to create a medical data base for patients. However, This is the most complicated database I've seen and the best. So, how do I use create form for use on my personal computer first before trying to use them over the net! 9i keeps asking me to log in! I don't want to log in! I just create test forms on my personal PC.
Please Help
Wil

You can create a Form which is not based on a table but it makes like more difficult since the main wizard for setting up a block is focused on reading information from the database table (so it knows what type and size to make the fields).
If you really want to do this properly I would strongly suggest you get logged on. You need to set up the tnsnames.ora file - this is the file which tells forms how to connect to the data base. When you set up Forms you should get menu item on the Start bar for "Application Server" choose this then the option for Configuration and Migration and use the Net config assistant (you should probably read up on this before using it so you know the options.

Hi,
We dont want to use the default JPA provider "Toplink *Essentials*" that comes with OC4J. Rather we want to use Oracle Toplink 10.x
I downloaded [Oracle Toplink 10.x|http://www.oracle.com/technology/software/products/ias/htdocs/1013topsoft.html] and followed the installation instructions:- http://www.oracle.com/technology/products/ias/toplink/doc/10131/install/install.html#CHDBBIFB

rashant,
Hi, there are currently the following providers to choose from - you may want to consult your rep for any details on moving from 10.1.3.4 to 10.1.3.5.
1) TopLink or EclipseLink using EclipseLink JPA - the RI for JPA for WebLogic, OC4J and GlassFish
- EclipseLink JPA is focus of all current JPA development as part of EclipseLink and TopLink
2) Another open-source JPA implementation like OpenJPA or Hibernate
Deprecated:
3) TopLink using TopLink JPA - replaced by (1) TopLink using EclipseLink JPA
4) TopLink using TopLink Essentials JPA - replaced by (1) TopLink using EclipseLink JPA

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=<<servername or IP address>>)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=XE)
)Hope this helps,
Craig B-)

          Could you tell me what specifically should I use for Oracle database instead of
          jdbc:cloudscape:rmi:CloudscapeDB;create=true.
          Can I use jdbc:weblogic:oracle for jdbc:cloudscape:Commerce? I am not familiar with
          Cloidscape URLs and drivers.

Clustering using Oracle ADF - CHECK_STATE_SERIALIZATION=all

We are using Oracle ADF 11.1.1.6. We have started testing our Oracle ADF application for the cluster compatibility and used following document. We have coded all recommendations given in the document including enabling all applicable java classes to serialization and also setup adf_config.xml <adfc:adf-scope-ha-support>true</adfc:adf-scope-ha-support> and <adf:adf-scope-ha-support>true</adf:adf-scope-ha-support> exactly as per given in the document.
http://docs.oracle.com/cd/E12839_01/core.1111/e10106/adf.htm
Now, to check High Availability on a standalone web logic server for debugging purpose we configured Java Option "-Dorg.apache.myfaces.trinidad.CHECK_STATE_SERIALIZATION=all" as per the recommendation.
After setting this flag system started throwing bunch of errors similar to the error given below.
[2012-07-26T14:17:43.602-04:00] [OPERA_ADF1] [ERROR] [] [org.apache.myfaces.trinidadinternal.config.CheckSerializationConfigurator$MutatedBeanChecker] [tid: [ACTIVE].ExecuteThread: '17' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: edozer] [ecid: 64915ee7c1860d85:40a983d1:138bf4550b2:-7ffd-0000000000005fcb,0] [APP: OperaApplications_o90_smoke#V9.0.0] Failover error: Serialization of Session attribute:data has changed from oracle.adf.model.servlet.HttpBindingContext@365f8709 to oracle.adf.model.servlet.HttpBindingContext@36b6565b without the attribute being dirtied
The question is what are we missing here?
Please note that our application is still missing ControllerContext.getInstance().markScopeDirty(pageFlowScope); but when I tried to create a sample application and deliberately left the "markScopeDirty" using below code the above mentioned error was not reproduceable.
public class myBackingBean
     public void changeValueButton( ActionEvent ae )
     Map<String, Object> pageFlowScope = AdfFacesContext.getCurrentInstance().getPageFlowScope();
          pageFlowTestBean obj = ( pageFlowTestBean )pageFlowScope.get( "pageFlowTestBean" );
          System.out.println( "Old Value " + obj.getYVar() );
          obj.setYVar( "New Value" );
          /* ControllerContext.getInstance().markScopeDirty(pageFlowScope); */
Can anyone shade more light on it?
Also, I would like to know that can someone guide me what is the best practice to perform ControllerContext.getInstance().markScopeDirty(pageFlowScope);. Because developers can easily miss this statement and I didn't find any easyway to search the code that is missing this statement (I have already tried Jdeveloper's Audit feature and it works for very few cases).

We checked the ADF source (pasted below). It reads that markScopeDirty is getting skipped if ADF_SCOPE_HA_SUPPORT is not configured but when we debug our application the serialization fires after every pageScope/viewScope variable gets changed regardless of markScopeDirty() is being called or not. That signifies that markScopeDirty() call is not needed. Do we really need markScopeDirty() everywhere in our application or this is just a public helper method to manually trigger replication for some exceptional case? Can anyone from team Oracle explain this behavior?
@Override
public void markScopeDirty(Map<String, Object> scopeMap)
Boolean handleDirtyScopes =
(Boolean)ControllerConfig.getProperty(ControllerProperty.ADF_SCOPE_HA_SUPPORT); //checks for adf-scope-ha-support
if (handleDirtyScopes.booleanValue())
if (!(scopeMap instanceof SessionBasedScopeMap))
String msg = AdfcExceptionsArb.get(AdfcExceptionsArb.NOT_AN_ADF_SCOPE);
throw new IllegalArgumentException(msg);
((SessionBasedScopeMap)scopeMap).markDirty();
}

Workaround for using Oracle JDBC extension with WLS pooling

Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.
Best regards,
Eugene Voytitsky

Hello Eugene Voytitsky,
Thanks Eugene Voytitsky for your idea
I have tried the solution suggested by You, but it did not work.
It still throws ClassCastException.
I am sorry for posting the whole code of two classes below.
I did this to give you more clarity.
I am also indicating the place where the exception was thrown..
Please let me know if I am doing something wrong.

The line 46 in DataSourceConnectionWrapper
corresponds to
return new WeblogicConnectionWrapper((OracleConnection)con);
Which I feel is logical as the connection which we get from Weblogic
datasource cannot be type casted to OracleConnection

Problem in using OracleAS Web Cache as Load Balancer

I have two machines:
aimssrv.world.com and aimsrep.world.com.
Both of above machines are running Redhat Linux AS 4.
On both machines, I have installed Oracle Forms and Reports 10g Services. I have deployed my application on both machines.
I am able to access my application at aimssrv.world.com by doing:
http://aimssrv.world.com:7778/forms/frmservlet?config=aims
and I am also able to access my application at aimsrep.world.com by doing:
http://aimsrep.world.com:7778/forms/frmservlet?config=aims
I have implemented OracleAS Web Cache at machine aimssrv.world.com, and have enabled the Load Balancing.
In Origin Servers, its showing me two servers:
Host => aimssrv.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
Host => aimsrep.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
In Site Definition, I have following information:
Host Name=> aimssrv.world.com, PORT=>7777
In site-to-server mapping, I have following information:
Priority      Host Name      Port      ESI Content Policy      Host Name      Port      Proxy
1      aimssrv.world.com      7777      Unrestricted      aimssrv.world.com      7778      No
aimsrep.world.com      7778                                    No
2      *      7777           Exclude Fragments      aimssrv.world.com      7778      No
3      *      *           Exclude Fragments      aimssrv.world.com      7778      No
In Session Binding, I have selected "JSESSIONID" as session, and "OC4J-based" as session binding mechanism.
Now please guide me as how would I run my application by using the OracleAS Web Cache?
What would be the URL?
Do I need to make any changes in httpd.conf files of aimssrv.world.com and aimsrep.awc.com?
Please guide.
Thanks and regards

hi,
i hv recently configured webcache load-balancing for my 2 mid-tiers.I did not upgrade pre-requisite webcache upgrade patch 4569559 to my 10g rel 2 10.1.2.0.2 OAS and it still worked a bit but I do have some doubts why oracle recommends installing this patch before configuring webcache load-balancing.Have u?
btw u need to collapse all the features of webcache of caching to turn on http load-balancing.U need to add a parameter to internal.xml (LOADBALANCE ON="YES") and register origin servers of both servers with each other and map ur sites so that origin servers of both servers will cater sites of server1 and server2 at the same time.
what worked for me is i registered origin server of server1 at server2 and origin server of server2 at server1 and mapped site of server1 (http://server1:port/forms/frmservlet?config=something) to work with origin server of server2 as well at site-to-server page so that origin servers of both servers will load-balance my server1 site and vice-versa.
But still its not seamless.The initial site request was still being routed to the server which is DOWN first and not seamlessly routed to other server which is UP.Maybe webcache upgrade patch would hv done this seamlessly????

Workspace Congifuration Using Oracle Application Server

Hi All,
Is there some of you ever try to configure the Hyperion Workspace 9.3.1 using Oracle Application Server 10.1.3.1.0..??
I've tried, but it seem like failed. I cannot access the workspace at all.
I did some configuration in this part :
- Workspace - Administration - Server Properties
- configure the portlet.xml at <>\Workspace\applications\Workspace\workspace\WEB-INF\
- change the config.bat at D:\Hyperion\BIPlus\bin
Any suggestion for this problem..??
Thanks.
Regards,

1. Correct the following path
extension_dir = "D:/php/ext"
(if your php is installed in D:/php, the above path is correct.
2. Find the line ;extension=php_oci8.dll
delete comment sign (;) and it will be :
extension=php_oci8.dll

Is it possible to use Oracle Memebership Providers with Oracle Express

I am using Oracle Express as development database and I was able to create the ORA_ASPNET_ tables and procedures but when I try to use Microsofts "ASP .NET Configuration" tool to create users and roles I get this error message: OracleConnection.ConnectionString is invalid
When I use the connection string in code to connect to the database I am successful, I am able to open and close a connection to the Oracle Express database.
This is the connection string I am using: <add name="OraAspNetConString2" connectionString="DATA SOURCE=localhost:1521/XE;ENLIST=false;METADATA POOLING=False;PASSWORD=CREDENTIALSMGR;PERSIST SECURITY INFO=True;STATEMENT CACHE PURGE=True;USER ID=CREDENTIALSMGR;" providerName="Oracle.DataAccess.Client"/>
So I am wondering why when I run the application and the membership class tries to verify the user I get the error message: OracleConnection.ConnectionString is invalid
I have been looking at this a couple of days now so not sure what the problem is, any help?

I suggest that update your machine.config file under your
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG.
There is one following entry. You may try to update the
connectionString with a valid string value.
<add name="OraAspNetConString" connectionString=" " />
