MDM Database command execution error. A SQL statement failed to execute

Hi,
When we tried to execute an MDM Java query modify/create, we get the following dump.
Is this anything to do with the parameters that we pass or is it something to do with the database ?
We have checked the code and we do not find anything wrong with the code at all.
We are using Java API 5.5.63.73 and calling MDM API's using WebDynpro for Java.
I have noticed this issue has been raised here as well :
Database command execution error. (While mounting a repository)
com.sap.mdm.commands.CommandException:
com.sap.mdm.internal.protocol.manual.ServerException: Database command execution error. A SQL
statement failed to execute. The actual error may have been written to a log file. at
com.sap.mdm.data.commands.ModifyRecordCommand.execute(ModifyRecordCommand.java:163) at

Subramanian V.

Hi Subramanian ,
The error looks more like a problem with the data base or MDM system rather than the java code.
Which is the underlying database you are using with MDM? As some users have faced some difficulties when working with the DB2 Data base,If this is the data base you too are working upon then may be the issue could be similar,if possible try using the Oracle or SQL data base as these databse show more compatibility than a DB2 when working with MDM .
Also check the MDM users autorization and authentication to modifyor create recordrs in MDM.try given the user the ADMIN rights,and tehn try and see if teh user is able to modify/Create the mdm records.
Lastly you can check the database instance and listener configuration correctly.try restarting the Database service form the system if possible.
Hope It Helped
Thanks & Regards

I have saw a report like this:
The report has executable "XML Publisher Data Template Executable", short name as "XDODTEXE", application "XML Publisher",execution method "Java Concurrent program". Also the report has a XML publisher Data Template and Data definition and in the data definition a .xml file is attached.
I could not understand what is the data source?
Could anyone help me on how to build or update this type of report?
Is there any link or help docs which has proper step by step procedure to build this type of xml publisher report?
Please help.
Thanks.

The xml file which is attached to the data definition is the data source and it has sql queries and structure of xml file.

Way to display the output of tail command in a Java app

Hi,
I have a Java app running in the Linux environment. The Weblogic outputs get written to a log. I would like to design a screen in my app that will enable me to monitor my logs. I normally log into the Linux machine and do a tail -f on the log.
tail -f Managed_1.logI would like to run this tail -f command from my Java app so that I am able to view the log proress from my app itself. I know we can use Runtime to run external programs but this is a case where a command will be executed continuously and the output will need to be displayed in my app, more specifically on a JSP.
Any ideas would be most appreciated.
Thanks and regards,
Ganesh

I had a look at the API for the Process class which
lists an abstract method called getOutputStream().
What I am not clear is that the documentation says
that the exec method of Runtime will return an
instance of a subclass of Process. Does this mean
that the getOutputStream() method would have already
been coded for the subclass instance returned?Yes.
And even if we do get the OutputStream from the tail
-f process, we will still have to read and display
the info on a line by line basis. Will this happend
to be fast enough to macth atleast to some extent the
speed at which the log is written to?There are two ways to answer this:
1. Ask somebody who knows how fast the log is written to.
2. Try it and see.
My approach would be the second option.

Running curl command from a java program using Runtime.getRuntime.exec

for some reason my curl command does not run when I run it from within my java program and errors out with "https protocol not supported". This same curl command however runs fine from any directory on my red hat linux system.
To debug the problem, I printed my curl command from the java program before calling Runtime.getRuntime.exec command and then used this o/p to run from the command line and it runs fine.
I am not using libcurl or anything else, I am running a simple curl command as a command line utility from inside a Java program.
Any ideas on why this might be happening?

thanks a lot for your response. The reason why I am using curl is because I need to use certificates and keys to gain access to the internal server. So I use curl "<url> --cert <path to the certificate>" --key "<path to the key>". If you don't mid could you please tell me which version of curl you are using.
I am using 7.15 in my system.
Below is the code which errors out.
public int execCurlCmd(String command)
          String s = null;
          try {
              // run the Unix "ps -ef" command
                 Process p = Runtime.getRuntime().exec(command);
                 BufferedReader stdInput = new BufferedReader(new
                      InputStreamReader(p.getInputStream()));
                 BufferedReader stdError = new BufferedReader(new
                      InputStreamReader(p.getErrorStream()));
                 // read the output from the command
                 System.out.println("Here is the standard output of the command:\n");
                 while ((s = stdInput.readLine()) != null) {
                     System.out.println(s);
                 // read any errors from the attempted command
                 System.out.println("Here is the standard error of the command (if any):\n");
                 while ((s = stdError.readLine()) != null) {
                     System.out.println(s);
                 return(0);
             catch (IOException e) {
                 System.out.println("exception happened - here's what I know: ");
                 e.printStackTrace();
                 return(-1);

Running a perl shell command through a java program on linux platform

i'm trying to execute the following command in a java program "perl xxx.pl" using the runtime.getruntime method
here is the piece of code
String[] cmd={"perl","-c","AraMorph.pl",""};
Process p = Runtime.getRuntime().exec(cmd,null,new File("/home/ahmed/buckwalter_morphan_1/data"));
p.waitFor();
BufferedReader in=new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line=in.readLine())!=null)
System.out.println(line);
but it doesn't output anything even if i tried to print the output to a file
i'm trying to execute this program on linux platform but its working properly on a windows platform
thx
raar

String[] cmd={"perl","AraMorph.pl"," </home/ahmed/in.txt"," >/home/ahmed/ast.txt"};
Process p = Runtime.getRuntime().exec(cmd,null,new File("/home/ahmed/buckwalter_morphan_1/data"));
BufferedReader in=new BufferedReader(new InputStreamReader(p.getErrorStream()));
String line;
while ((line=in.readLine())!=null)
System.out.println(line);
p.waitFor();
String str2=p.getInputStream().toString();
System.out.println("==================================="+str2);
and it still outputs nothing but goes in something like infinite loop or as assumed in the article u suggested a deadlock but even all solutions to all pitfalls didn't succeed

Running ssh command in a java application

Hi there!
I am trying to run a ssh command from a java application cause I need to store the result.
Actually I can run this command in the cygwin shell so I need to open the shell and run the command, all trough java.
so, what my process needs to do is:
1) open the cmd
2) run C:\cygwin\cygwin.bat
3) execute the ssh command
ssh -l fip-user ipdb fip 42704) print the result of the ssh command.
Note that the cygwin opens in the same command line window and so will print it's result to the same process inputstream

Use "Runtime.getRuntime().exec()" to execute the SSH program,
and you can then get the output of the SSH program
via the getInputStream() method on the returned Process object.
Note: there are many pitfalls with this. In particular, most people don't know
they should create separate threads to drain the input/output pipes.
See this excellent classic article http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html

Creation Of Custom Queries of Execution Type Java.

Hi All ,
I want to know if I can create Custom queries of Execution type java which have Query Executor class.
I got this requirement because I got to customize "Search Master Agreements and Agreements".
It seems like it's not possible as Query Executor Class is uneditable so no chance of deploying any class file in server and trying out the ways...
Any approach exists to customize these type of queries.?
Regards,
Uday

Hi
I understand your requirement is to customize Search Master Agreements and Agreements query and display the new custom report in the Contract Management dropdown on workbench along with other queries.
This could be achieved by duplicating original query i.e.Search Master Agreements and Agreements, customize and save it, go to Query Group in set up, identify and open the query group containing the original query and add the new customized query as query reference.Also don't forget to remove the original query from the query list.

An unexpected error during Command execution

Hi,
I am using Project Server 2007 SP 2 at the moment. One of our user keeps encountering this error "An unexpected error during Command execution" for a project file. We tried to restore the earlier version of the plan using Administrative restore.
But it only works as a temporary fix as the problem keeps reapprearing. Kindly help.

Only SP2 for Project 2007? Probably not worth trying to debug, with 2007 it is almost essential to have SP3 and the very last cumulative update for Project pro and Server. 2007 was a very buggy version (they were forced to release at same time as Office
2007 and it was too soon).

Remote command execution via ssh on ips sensor...

I am attempting to execute a command remotely via ssh so that I can collect the information on another host.
ex: ssh -t username@sensor show tech-support
Instead of the output I expect, I receive an error message: Error: Received invalid command line argument.
Is this type of remote command execution supported by the sensor?

Not true, i already created scritp to automaticly backup the IPS

How to run a openssl command from a java program

Hi All
Please suggest on how to run a openssl command from a java program.
I am using this
Runtime runtime = Runtime.getRuntime();
runtime.exec("openssl pkcs8 -inform der -nocrypt test.der result.pem");
This is suppose to take test.der as input and create result.pem.
There are no errors but the file result.pem isnt created.
Thanks in Advance

First off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.
