Starting JDBC Connector datasource service Automatically

Hi Members,
We have a custom development in webdynpro using ejb to access data from a oracle database (on a different server). we have created a JDBC Connecter datasource on the j2ee egine and defined a alias for the same.
when ever the oracle database is restarted for whatever reason, the datasource service stops and is not up when the database is up.
In order to restart the service Administrator has to go J2ee Admin and start explicitly. we would like to know of any mechanisim by which the service starts automatically when the database is up.
Thanking in Advance,
Regards
Vinay Rane

When I installed it on my windows server it indeed asked for a J2EE user and password, cant remember it exactly but i kept it default.
It made a windows user j2eadm which i use to log into windows. But now, where do i enter this password? In my http://localhost:50000/irj/portal or what? I really cant figure out where to find the tool itself.
In desperate need of your less-stressfull moments,

JDBC Connector - Datasource issue

Hi,
We have a datasource created in JDBC Connector in Visual Admin Services. The issue is whenever there is a connection failure due to network or the database system is restarted the JDBC datasource doesn't work and we get invalid connection in our application.We have to stop and restart the datasource through Visual Admin to make it work.
Is there any resolution that we dont have to restart the datasource manually in case of connection failure.
Appreciate your support

Hi,
I had same problems!
I only know of a workaround for JMS adapter which showed same issues after a MQ restart. There an option got introduced to "ping" the source / target to recreate the connection by a parameter to be set in the channel itself. I'm not sure this option is also available for JDBC channels...
Does anybody got news here?
Thanks,
Kai

JDBC Connector service in visual administrator

Hi All,
JDBC Connector service in visual administrator is not getting start or stopped.
I checked in Visual admiistrator ,then in JDBC Connector. On right click to JDBC Connector, Start or stop options are disabled.
It may be because of wrong configuration,please provide me the solution for this or provide me the configuration settings for JDBC Connector, so that i could recheck.Please tell how to start JDBC Connector from visual administrator services.
Points will be awarded.
Thanks & Regards,
Aman.

Hi Aman,
> i am also not able to start/stop data sources that i have created manually
On such datasources, for each one there is one .xml entry (the DS definition file)and below that, the datasource settings can be reached. If you mark the first one - the xml definition file - you get a blank screen right-hand, but at the same time, the "Stop" button (tooltip: "Stop Selected Standalone Application"; or the corresponding "Start" button, depending on the DS state) gets clickable.
This does not hold for the preconfigured default DS (which also has no xml entry).
Hope it helps

JDBC Connector service - lookup fails

Hi all,
We have EP6 SP14 on Linux. I am trying to access some data from external database SQL Server 2000. I tried two different sets of drivers in Visual Admin --> Services --> JDBC Connector but the context lookup fails.
Set 1:
msbase.jar,msutil.jar, mssqlserver.jar
JDBC 1.x compliant
Driver class: com.microsoft.jdbc.sqlserver.SQLServerDriver
also tried com.sap.jdbc.sqlserver.SQLServerDriver
URL: jdbc:microsoft:sqlserver://sqlser2:1433;databaseName=repdb
Set 2:
P9sqlserver.jar, P9base.jar, P9util.jar
JDBC 1.x compliant
Driver class: com.sap.portals.jdbc.sqlserver.SQLServerDriver
URL:jdbc:sap:sqlserver://sqlser2:1433;databaseName=repdb
The connection works fine if use the traditional way
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://dbsql2:1172","<userid>","<passwd>");
(Note no db name here)
Can you help me let me know where I am going wrong. Thank you in advance.

Hi Steve,
I believe you've gotten closer to tracking down your issue, but there
are a couple style issues here I thought I'd comment on for general
consumption.
1) Your Collector will issue a query against the database, then it will
return a Record object. Each column in the database is mapped to the
RXMap object within that Record, in the form 'rec.RXMap.METHODNAME',
'rec.RXMap.CLIENTIP', etc. Since 'parse()' is a member function of
Record, 'rec' in this case is simply 'this'.
2) You then proceed to copy all of those fields from
this.RXMap.something to this.something, and then you proceed to copy
several fields from this.something to
this.somethingelsethatlookslikeasentinelfield. All of this is completely
unnecessary.
3) As long as you don't have to do any further processing on the values
in the source data (as with REQUEST_TM), you can skip everything in
preParse() and all of the this.* = this.* stuff in parse(), and simply
put entries like this in Rec2Evt.map:
iuid,RXMap.LOG_ID
cv30,RXMap.METHODNAME
cv31,RXMAP.CLIENTNAME
The Collector will automatically copy the information from the fields on
the RHS of Rec2Evt.map into the Sentinel Event fields on the LHS of
Rec2Evt.map.
Thus your entire Collector can be boiled down to this:
Collector.prototype.initialize = function() {
this.PARSER.getOffsetData = function(input) {
if (typeof input.RXMap != "undefined") {
return input.RXMap.REQUEST_TM;
conn.addParser(this.PARSER.getOffsetData);
return true;
Record.prototype.parse = function(e) {
var dt = new Date(this.RXMap.REQUEST_TM.substr(0,
this.RXMap.REQUEST_TM.length-2));
e.setDeviceEventTime(dt);
return true;

Hi to all,
I would want to know if it is possible and how to start this service automatically with an scheduled job system.
The server is restarted every week automatically an someone has to start de Control Centre Service manually typing: user, pwd, server, port and service.
Thanks in advance,

what you can do is create a script which will get executed once your server is restarted .
inside the script you need to do the following
go to the directory : $OWBHOME\owb\rtp\sql
connect to the repository owner with sqlplus
start the sql file start_service.sql

JDBC Connector in NetWeaver Dev Studio WebAS

Hello,
I am attempting to deploy a web module that utilizes a WebAS datasource for an external Oracle database. I expect to add a JDBC Connector leveraging the Oracle JDBC driver. I have been unable to deploy the Oracle datasource.
I receive the stack trace below whenever I attempt to Start the datasource. I find many posts asking about this error but never have I found an answer as to the cause or resolution. OSS Note 751175 describes this as a classloader problem with connectors but it does not offer any repair method that works with this problem (in my case).
I've had this problem with NetWeaver SP7 and it remains with SP10.
Does anyone have explanation? Can I expect to test such applications in NetWeaver's standalone WebAS?
Best regards,
Gary

Hello Benny,
One of my co-workers resolved the problem which boiled down to driver configuration confusion. Here's what we learned:
No SDA component was required though this was a good exercise for us to go through.
The driver (JAR or ZIP) file can be added simply using the Visual Administrator JDBC Connector Runtime tab.
We were not able to activate more than one type of datasource at a time (feature, bug or something else?)
The following configurations start okay:
**Starts***
Driver: Oracle's classes12.zip
JDBC Version: 1.x
Driver class: oracle.jdbc.driver.OracleDriver
Database URL: jdbc:oracle:thin:@host:port:instance
User&Password specified.
**Starts***
Driver: Oracle's 1.4 ojdbc14.jar
JDBC Version: 2.0
Driver class: oracle.jdbc.pool.OracleDataSourceFactory
Datasource type: ConnectionPoolDataSource
CPDS Classname: oracle.jdbc.pool.OracleConnectionPoolDataSource
Additional properties:
URL = jdbc:oracle:thin:@host:port:instance
User = xxxx
Password = yyyyy
**Will not start but the failure is expected***
Driver: Oracle's classes12.zip
JDBC Version: 1.x
Driver class: oracle.jdbc.pool.OracleConnectionPoolDataSource
Database URL: jdbc:oracle:thin:@host:port:instance
User&Password specified.
We do need to run multiple datasources using Oracle and Sybase so I'm hoping the issue we encountered is simply configuration issues again.
I appreciate your time and feedback Benny!
Best regards,

How Do You Re-Start CF Admin? / Service Stopped, Won't Re-Start

CF Admin suddently stopped, and won't re-start. Have been using CF9 on Win7/x64 for months with no problems. Was trying to install a Teradata JDBC driver. After copying the .jar file to the C:\ColdFusion9\lib folder, I went into Services and tried to STOP and RE-START the Cold Fusion Application Server. While Windows was trying to stop the service, got an error that it was unable to stop the service, and it locked up. Unable to stop or start service.
After re-booting PC, Services showed all CF services started normally, but can't run CF Admin, and can't access any data sources or run any .CFM programs. It appears to be stuck. I tried stopping and re-starting all ColdFusion services, which stopped and re-started fine, but still get error when trying to run CF Admin. Appears something is hung-up. Appreciate any advice on how to get the service re-started. Can't run any .CFM programs as all DSNs are unavailable. Below is error message when trying to access CF Admin:
Error Occurred While Processing Request
The DataSource service is not available.
This exception is usually caused by service startup failure. Check your server configuration.
The error occurred in Application.cfm: line 88
Called from Application.cfm: line 76

Thank you,

Thank you for taking the time to reply. Actually, thanks to some Google-ing, was able to find and fix the problem. The problem began when I tried to install and verify a Teradata JDBC driver. When I tried to stop and re-start the service, it locked up. Then would not start again.
I discovered the SERVER.LOG file should tell you exactly what the error is, and it did. It showed an invalid character in 4 places in the neo-datasource.xml file (in the C:\ColdFusion9\lib folder). So my options were to either remove the invalid characters, or replace the neo-datasource.xml file with the last good working backup.
When this file goes corrupt, the .BAK version is used, and then it goes corrupt when you try to stop-restart the service, and you're left with no backup (.BAK) file. Fortunately, I had another working version of the file on another computer (configured same as this one). So I copied it to my computer, and replaced the bad one, then re-booted (could have stopped and re-started the service, but decided to re-boot, which does the same thing).
The CF Admin started normally. I was then able to correctly install the Teradata JDBC driver. The cause of the problem was that I had failed to also list the tdgssconfig.jar file in the JVM section of CF Admin (even though the instructions I had said the Class 4 driver did not require this file, and that CF would ignore it). But apparently, it is needed.
Anyway, after all this, the Teradata JDBC drivers verified successfully. My CF test server is now connecting with the corporate data warehouse in Houston, over 1,000 miles away, using the newly installed JDBC drivers. And queries and .CFM files are running normally. Thank goodness.
Anyway, thanks again for the reply. Much appreciated. If anyone else has a problem getting CF Admin to start, after tinkering with installing new DSNs, remember to ALWAYS MAKE A BACKUP of your neo-datasource.xml file before you begin. Better safe than sorry. Regards,
Gary

JDBC Connector and pooling problems. Should be ConnectionPoolDataSource ?

Ciao all,
I am testing the JDBC Connector by Sun.
As you know, such JDBC connector is a JCA connector which can be used to
wrap a JDBC Driver or a JDBC Data Source or a JDBC
ConnectionPoolDataSource into a JCA connector.
Such JDBC Connector exposes to the client component the usual DataSource
interface, so that an application that was developed using a DataSource
can be easily migrated to a JCA enabled application: the application in fact will use the JDBC connector as if it was a DataSource, without
knowing that actually it is a JCA connector.
Here is my problem: the JCA architecture provides a pool. Therefore, I'd like the JDBC Connector to appear to the client as a
ConnectionPoolDataSource rather than a simple DataSource.
In fact, I have an application that performs a JNDI lookup to retrieve a JDBC data source. Then, if the obtained data source is instance of ConnectionPoolDataSource then the applications will use the SQL Connection and will closes it to release it back to the pool.
But if the data source is instance of DataSource, then the application
will retrieve a SQL connection, will use it, and will keep it in its own pool in order to reuse the SQL connection for better performance.
Now, if such application works with either a DataSource or a ConnectionPoolDataSource everything works properly, but when it works
with the JDBC Connector it fails: the JDBC Connector in fact appears as
a simple DataSource without pooling, so the application keeps the
obtained SQL connections in its own pool. But actually, the JDBC
Connector is a JCA connector which has a pool too, so the SQL connection
is kept in two pools and as a consequence, the JDBC Connector pool invalidates or destroy the connection in its pool, and the application, which is unaware, keeps in its pool a reference to an invalid connection, which leads to a SQLException at runtime.
So my question is: don't you think that the JDBC Connector should implement ConnectionPoolDataSource rather then DataSource, since it is a
JCA connector that offers pool services ?
And if so, is there a way to submit this question to someone working for Sun ?
Thank you for your time.

Portal Test Connection Failed for JDBC Connector

Hi,
We are trying to create a JDBC system in EP to connect SQL Server 2005 database. Our aim is to build a model in VC using data services from SQL Server 2005.
We deployed the Driver file sqljdbc.jar and connection was successful when tested by creating a data source in Visual Administrator-> JDBC Connector
We have created a system in EP with user mapping type (admin,user) and user mapping also done for system alias with the SQL Server administrator user id and password. UME is maintained in ABAP Stack. When we try for test connection with the system created in EP for JDBC connection, the system throws an error message like Connection failed. Make sure user mapping is set correctly and all connection properties are correct
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the back end application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure user mapping is set correctly and all connection properties are correct.
The following are the URL and driver class name:
URL: jdbc:sqlserver://<host_name>:1433;DatabaseName=db_ name
Driver class name: com.microsoft.sqlserver.jdbc.SQLServerDriver
Is there any other setting to be maintained in the Visual Administrator or in the Portal?
Kindly let us know any clue to overcome this issue.
Quick response highly appreciated.
Regards
Saravanan.r

Hi Saravanan and Sathish,
not sure how far you got with this. I had the same problem or at least a very similar one with access to MS SQL Server 2005 and solved it. I followed essentially very similar steps with a couple of minor twists:
1) copied the sqljdbc.jar file to the storyboard server and set the classpath environment variable to point to it.
2) I did not create a data source, just created a new driver "SQLServer".
3) Under Connector Container I cloned SDK_JDBC as "SDK_SSQL".
4) The Visual Composer property vc.bi.sqlEditor Enabled should be set to true for you to be able the SQL Editor in the Data Service in VC.
In the portal I created a system of type BI_JDBC from a template.
The connection url and driver class were as in the thread:
URL: jdbc:sqlserver:ipaddress:1433;DatabaseName=name
Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver
ConnectionFActoryClass as above under 3.
User rights: admin,user
The user mapping to the system alias should be as described.
This should allow you to use the data service in VC to access SQL Server tables. If access to stored procedures (sometimes quite useful) is required, this would need to utilise the p9sqlserver.jar file already on the server.
Best Regards

JDBC Connector : pool gets depleted

Hi,
we are currently working with SAP EP 6.0 SP2 and trying out some development work with the connector framework.
We are writing a component which uses the CF to retrieve information from a Microsoft SQL Server 2000.
The portal component works, we are able to retrieve the information from the DB, but after some time the request times out.
We monitored the connections for a while both on the J2EE platform and on the backend database and came to this conclusion : apparently each request - even by the very same user looking at the very same component, just but pressing the refresh button in the browser window - creates a new connection in the pool managed by the connector framework.
- result : the number of successful views of the components is equal to the number of Maximum Connections defined for the JDBC connector on the J2EE platform.
In our code we are using the close() method on the IConnection interface as indicated in the documentation that comes with the PDK.
Is this a known problem OR are we doing something wrong here ?
We suspect that there is something wrong in the implementation of the JDBC connector, which isn't handling the close method correctly.

In more general terms this issue raises the following questions :
- how does the Connector framework manage the pool of JDBC connections ?
- the fact that our component at each request (even after a refresh in the browser) causes the CF to create a new connection, does that mean we are writing our code incorrectly so that each request is indeed considered to be a unique and in need of its own database connection ?
We have tried to avoid as much reason as possible for the CF to generate a new connection : e.g. we have set up user mapping so that all users access the database with the same account. This should already eliminate the requirement to have a separate for each user. => in general : what are the different ways by which to control the generation of connections by the Connector Framework, for the JDBC Connector in particular ?
- So far we are writing the code accessing the SQL server straight into a JSPDynpage. Am I wrong in thinking that this is allowed. Although we intend to write a portal service as a wrapper for all database interaction in a later stage, for the simple exercises now we are directly using the CF service API in the portal components.
- by what algorithms does CF determine whether to take a connection from the pool or to create a new connection to the back-end system.
- Am I wrong in thinking that connection pool management is no longer the task of the developer when using CF ?
