MI Client & database connectivity

Hi,
I'm developing an MI based demo application and want to connect to database db2 on the mobile device. In the cilent APIs I could not find anything where I can specify the database or option for using serialization for that matter. Has anybody tried to connect with database? Please guide.

You can't do it from the API.
MobileInfrastructure (former MobileEngine) is a framework used for connecting to and extracting data from R/3 backend. There are just two ways to do it - Generic Sync or Smart Sync.
If you want to do direct database connection, you have to use the Java Platform features, JDBC or what driver you have on the mobile device. Howsoever, this is little wrongly.
Just curious, what for mobile device you bear in mind? SAPDB and MobileEngine are not designed for PocketPC. )
Anyway, this is a funny problem, please share your experience about it, when you establish the connection.
Good luck,
Todor

Database connection encryption and integrity with ColdFusion and Oracle thin client

As ColdFusion datasource we are using the Oracle thin client to connect with the database. So, basically we are using a JDBC URL such as jdbc:oracle:thin:@... and as Driver Class oracle.jdbc.OracleDriver. This works successfully however we would like to set encryption and integrity parameters as well. In Java this is done similarly by setting a Properties object prior to getting a connection as follows:
Properties prop = new Properties();
prop.put("oracle.net.encryption_client", "REQUIRED");
prop.put("oracle.net.encryption_types_client", "( DES40 )");
prop.put("oracle.net.crypto_checksum_client", "REQUESTED");
prop.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
OracleDataSource ods = new OracleDataSource();
ods.setProperties(prop);
ods.setURL("jdbc:oracle:thin:@localhost:1521:main");
Connection conn = ods.getConnection();
Is there a way that I can pass these parameters to the ColdFusion datasource. Ideally, I would love to do this centrally in such way that a change to all the cfquery or cfstoredproc is not needed.
I also know that in application servers such as Oracle AS there is an option when creating a datasource which says "Add Properties". In there you can add such properties. So, I was thinking of maybe creating a JNDI DS in the app. server and then magically connecting to it but this may have some impacts on the app.
Besides this I was also thinking of communicating with the CF datasource through the CF admin API (cfide.adminapi.administrator) and also the option of extending the Oracle driver so that when CF connects with it these params are already set.
I would love to have your professional opinion and suggestions on this.

I believe the thin driver actually needs the IP address (not the DNS name). Also, is "java" the name of the Oracle instance to which you are trying to connect?
Try the following:String driver = "jdbc:oracle:thin";
String dbIP = "W2RZ1NXG01's IP address";
String dbPort = "1530";
String dbSid = "java";
String dbUser = "Admin";
String dbPswd = "apassword";
String cnctStr = driver + ":@" + dbIP + ":" + port + ":" + dbSid;
try
    Class.forName("oracle.jdbc.driver.OracleDriver");
    con = DriverManager.getConnection( cnctStr, dbUser, dbPswd );
    stmt = con.createStatement();
    stmt.executeUpdate(createString);
    stmt.close();
    con.close();
catch(SQLException ex)
    System.err.println( "The following SQLException occurred: " + ex );
    System.err.println( "Message: " + ex.getMessage() );

Database connectivity problem with instant client.

Guys,
I've installed the Oracle instant client basic and ODBC files in my system.
But when I create a system DSN and test the connectivity my database connectivity,it fails with
ORA-12637:Packet receive failed error
My TNSNAMES reads below:

(Port = 1522)
I've placed my TNSNAMES and SQLNET file in the same folder having the instant client files and I've set my TNSADMIN,LD_LIBRARY_PATH and PATH environmental variable to the folder location.
Note:I'm able to connect to the database using SQLplus.
Thanks,

These days I very seldom use ODBC for Oracle - most recently it was simply to get Enterprise Architect to "talk" to Oracle. I never used it for my client applications (unlike in the fast distant past), so what I know about ODBC is seriously outdated.
Even so, a few comments. :-)
Have you tried creating a user DSN, in case a system DSN somehow works different environment wise?
The above error description sounds like the original TCP connection was successful (i.e. it is not a host unknown or not reachable error). Subsequent packets seem to fails.
To confirm, run the listener on namesrv1.xy.zz.com with logging enabled and have a look at the listener.log - does it show a connection being accepted/handled from your PC when you use the ODBC DSN?
Have you tried the Oracle ODBC drivers? When getting EA connected I had problems (also with Instant Client) and Microsoft ODBC driver for Oracle. Downloaded and installed the Oracle ODBC driver and it worked just fine first time around.
PS. You should raise this topic on the Instant Client Forum instead.

Oracle 10.2.0.4 client/ODP connecting to 11g database

Hi Folks -
Are there any know problems using an Oracle 10.2.0.4 client and the 10.2 ODP/ODAC client to connect to an 11g database?
Normally ,we'd use the Oracle 11g client/ODP but it is giving us errors so we need to go back to 10g
..any foresee-able problems with this?

soryy it took so long to reply.
we hit a bug which was supposed to be fixed in 11g client but is still there. OraOps11x.dll causing IIS 6.0 to crash. Took us a week to figure out what it was and didn't even consider it being an error caused by the 11g client until MS support pointed it out in a dump file we had them analyze. Oracle support confirmed it was true and last I heard they plan to have it fixed in the next update to the client, which they say is scheduled for end of July 2008. I hope it is fixed, because we're running into other problems with the 10.2.0.4 client also (ORA-21500 [%],[%],[%],[%],[%]).

Installation problem with NW'04 SR1: database connection failed

Hi all,
while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had

Closing the database connection after report in a server application

I searched these forums and the internet for a definitive answer on asking the Crystal SDK for java to close the jdbc connection after it has generated a report. We have been using the Crystal Report SDK to generate reports within our JEE application, built upon the Spring framework, for the past two years. It works well, especially if you prepare views in the database for your reports.
From what I can tell once you have used ReportClientDocument to create your report you all the close() method to release resources associated with report generation, but this does not close the jdbc database connection.
Further research states that if you are using the CrystalReportViewer you can call the dispose method to close the database connection. We are not using JSP nor this class, so that does us little good.
Finally I found a post that one could call ((AdvancedReportDocument)reportClientDocument.getReportSource()).dispose(). This doesn't drop the connection either.
Each report actually opens 3 connections according to SQL Server. Each report will reuse the connections it has open, so for 50 reports, theoretically, we could have up to 150 connections. We explained to our client those connections remain inactive, however this is unacceptable to our client as they would like to minimize the number of connections left open to their database.
If anyone can post any further information on this issue, it is much appreciated.

Yes, another team member found the issue. Quite embarrassing really I didn't see it. I was looking for the answer within Crystal's libraries. It had nothing to do with Crystal.
The developer who wrote the helper code for using Crystal first opened a connection to the datasource for the live production database and read that connection information for the report. Next he set that connection information in the report template's PropertyBag, then ran the report. The developer however forgot to close the connection he used to look up the connection info, leaving a memory leak and using up all the connections.
I'm glad you inquired. I forgot to post the resolution here.

Creating new Data Source Error - Database connection Failed

Any help is appreciated.

Datasource for the application.
I have created a sql db for this planning application (my datasource). See my first message for more details.
When you create a new planning application, you need to associate it with a data source. Since this is a new install, I don't have any data sources available yet.
So, "To create, edit or delete data sources, click Manage Data Source."
This page lets you validate your connection to the database and essbase server. My essbase server connection validates! The database connection does not validate after I enter all the relevant information.

So it does not let me create a data source for my new planning application, so I cannot create a new planning application.

Database Connection Error Cannot create PoolableConnectionFactory

Hello everyone,
Background:
I have a newly installed and configured Ubuntu server running Tomcat5.5 and Mysql 5.0. This server was created in an attempt to migrate from a Red Hat server in a similar configuration, running the exact same webapp. Most of the configuration/classpath differences between the two platforms have been ironed out.
The Problem:
When our webapp trys to connect to the database on localhost, an exception 'java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)' is generated.
The server.xml configuration is below:
<Resource name="jdbc/EconDollarsDB"
auth="Container"
type="javax.sql.DataSource"
username="user"
password="pass"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/DBName?autoReconnect=true"
maxActive="20" maxIdle="5"
/>I can connect to the database just fine using the command line client and the same username/password combo. This configuration has been working fine for at least a year on the older server. The only similar problems I have found on the net (meaning the same exception is generated) involve applets and attempts to connect to different hosts. This case involves a webapp, connecting to localhost, using a configuration that is known to work! I am simply baffled.
The following stacktrace is generated:

Hi,
Its clearly saying the connect permission is missing with the current available policy.
you add the following permisson entry to the <installed JRE>\lib\security\java.policy file.
(e.g) C:\Program Files\Java\j2re1.4.2_08\lib\security\java.policy
permission java.security.AllPermission;
grant{
permission java.security.AllPermission;
If the application is running standalone then the code is allowed uncontrolled access but for webapplicatons running through browser, the security check is performed for the configured JRE.

Database connection dailog opens with missing fields

Greetings all,
I have one user who has a couple reports that do not display all the fields in the database connection dialog box when she attempts to refresh the data in a report.
Normally this dialog box opens with the Datasource, UserID (of the last person who saved data with the report) and Database prefilled, so only the Password needs to be completed or the UserID changed.
For her (and this is only happening on a couple reports), only the Datasource text box is visible. The datasource is correctly filled in but in order to see the other fields, she needs to click the next button and then click back. Then all three fields - UserID, Password and Database need to be entered.
This only started in the past couple months and so far is only occuring with 2 reports, both new. Other new reports are acting normally.
We are using Crystal Reports XI with the latest service packs. Our reports are in a shared folder on the network. So far I have not been able to duplicate this behavior on anyone else' machine.
Any idea's on what might be causing this or how to correct it?
TIA,
Bob

I would check that persons database client and/or version of MDAC. May also be a permission issue on tables.

Database Connection Error

Hello,
We have crystal reports published on the BOBJ system and the datasource is SAP BI system . The reports were working fine
untill last monday when they started giving error " Database Connection Error " .
This is what happening, when we run the crystal report , it will come up with a pop up for selection and upon giving the selection and click on execute , it is giving error.
To start we have this issue in BOBJ dev system , but now we have the same issue in QA and Prod as well. I suspected
this has to do with license keys, but my BOBJ Admin *** basis team thinks otherwise.
I couldnt think of would have gone wrong or missing . Any ideas will be appreciated.
Thanks,
Ravi.

Ingo,
I tested the reports using the crystal designer, and they ran fine without issues . The same report when we run on BOBJ/infoview it is giving data base connection error. The same is happening across all the 3 systems( Dev, QA and Prod ).
I also tested the verify database on the crystal designer and it say " data is up to date".
As the client level integration seems to be working fine, I'm thinking there is a issue with server level integration.
Can you through some insight into the checks we can do get to the bottom?
Thanks,
Raju.
