SAP Dataservices with MYSQL

Hello there
I am having a problem trying to install DS. I have installed MySQL and set the Classpath to the location of the file mysql-connector-java-5.1.30-bin.jar. I was having issues with JDBC driver which picked from browse screen to the same file. Then I get the error in the screenshot.
Invalid JDBC driver, please check driver path. Am In missing something?
Any step by step guide ?
Appreciate help on this.
Thanks
Anand

Hi Anand,
Download the JDBC driver for your database to a location on the Data Services host system.
Copy the JDBC driver to all locations required by Data Services.
For Oracle and MySQL databases:
<LINK_DIR>\ext\lib
<BIP_INSTALL_DIR>\java\lib\im\<database_type>
database_type is mysql for MySQL, and oracle for Oracle.
<BIP_INSTALL_DIR>\warfiles\webapps\DataServices\WEB-INF\lib
Refresh the JDBC configuration.
Also refer the installation guide for DS for further reference.

Compiling PHP with MySQL

Hello all,
I am having trouble compiling php 5.2 (also tried 5.3). This is my configure line:
=======
./configure with-apxs2=/usr/local/apache2/bin/apxs with-mysql=/opt/mysql/mysql
=======
When I run "make", I get the following error:
=======
Undefined first referenced
symbol in file
mysql_set_character_set ext/mysql/php_mysql.o
ld: fatal: Symbol referencing errors. No output written to sapi/cli/php
collect2: ld returned 1 exit status
*** Error code 1
make: Fatal error: Command failed for target `sapi/cli/php'
=======
Here are my machine details:
=======
@[machine-name]-/usr/local/php5.2 # uname -a
SunOS [machine-name] 5.10 Generic_138889-03 i86pc i386 i86pc Solaris
@[machine-name]-/usr/local/php5.2 # isainfo -kv
64-bit amd64 kernel modules
=======
PHP compiles fine when I do it without MySQL. Any assistance is greatly appreciated.
Please let me know if you need additional information.
Thank you.

Hi,
first of all please mind that PHP 5.2 is out of support by the PHP developers on php.net. To receive bug fixes petc. you should use PHP 5.3.
Secondly it is worth noticing that there are three function libraries (extensions) which allow accessing the MySQL database. One is the classic "mysql" extension, one is called mysqli, with "i" as in improved, and a driver for the PDO database abstraction - PDO_mysql. You are only activating one of these, in most situations you want all three of them gor maximum application compatibility.
Now with PHP 5.3 PHP bundles an implementation complete of the MySQL Client functionality. So linking against a local installation is not needed. This implementation is called mysqlnd - MySQL native driver.
To build w/ mysqlnd and all three function libraries use a configure line like this:
./configure with-apxs2=/usr/local/apache2/bin/apxs with-mysql=mysqlnd with-mysqli=mysqlnd with-pdo-mysql=mysqlnd
If you have a strong reason for 5.2 or using libmysql I'd need more information, like which version of mysql was installed. Was it self-compiled or binaries from mysql.com etc. But I hope the above is fine.

SAP GUI with SNC logon and Hummingbird Exceed - SAP GUI window size issue

We have discovered an issue when SAP GUI 7.10 is used to logon via SNC and Hummingbird Exceed is used on the same workstation to logon to a UNIX system either via x-windows or telnet.
When the user logs onto a UNIX system using Hummingbird Exceed, then uses SAP GUI to logon to a SAP system with SNC authentication, the SAP GUI authentication works, but the favourites list is not fully displayed and has to be resized before any of the entries are available.
Has anybody else seen this issue, and do they know if there is a fix available ? We wondered if there might be an issue with fonts or some other sort of conflict between Exceed and SAP GUI, but it is strange that the problem only occurs if SNC authentication is being used, and when userid+password is used to logon to SAP the problem does not occur.
Cheers,
Tim

Hello Tim and Wolfgang,
I was curious too as I found it interesting... so I tested a few combinations, but could not reproduce what Tim has described, at least not before my CPU reached 100% and the applications stopped responding (~2GHz processor, 1GB RAM, 48 kbps connection, latency ~ 2 x width of the Pacific Ocean, but Backend 7.00!).
However I did notice some indications which might be a help (based on 7.00!):
Back in 4.?? there was a problem in that large menus could not be searched(!). Sorry, I don't have access to SAP now, but from memory the note # was 444043 (or very similar) and introduced a form routine for large menus - from a printscreen I still have the message number which led me to the note - 'I476(S#)'.
The system certainly distinguishes between MENU_TYPEs and the above note corrections could be found in several locations relating to the SAP menu 'S', the role menu 'A' etc, but I could only see that for favourites 'F' this is implemented for the menu search (when searching, not when loading).
@ Tim: Ask you customer to create a favourites menu which only has 1 node or max 2 (certainly not more than 4!) and ~ 20 executable objects in it (not more than 30!)? Can they under any conditions achieve the described problem with such a menu?
If not possible to reproduce, then the closest I could guess is a maximum limit of 4 nodes and max 30 objects for a 'F'avourite menu, before it is a minimum candidate for "performance problems" and consideration to be converted to a role ('A'ctivity group) menu instead.
Sorry that I can only help by speculating, because I could not reproduce what you have described.
Hopefully this problem will not happen to me in the New Year, and hope you will solve it for the rest of the year
Cheers,
Julius

OBIEE 11G with MySql Issue Hierarchy is not working..

Hi,
i am using the OBIEE 11G with MySQL DB. i have sucessfully created the RPD. i created the Hierarchy in the RPD. this is the scerario i have created.
i have only one data column created_at. by using this column i create 3 more logical logical columns, which are Year,Month Name,Week and created Hierarchy by taking the these columns only.
when i am viewing the result by taking the hierarchy it throwing the error systax error"ou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version".
but we selecting the year column it successfully nagvigating to the month level data but when selecting the Hierarchy directly it is unable to navigate from year to month.
please provide me the solution for this as soon as possbile i have an urgent requirement on this.
Thanks,
Yogi.

Hi,
Thanks for you post..
My Requriement is that we no need to create new columns we need to necessary columns in BMM layer only and we need to use them in Hierarchy.
Thanks,
Yogi.

Can' t connect Java with MySQL

My goal is to connect Java with MySQL. I found many solutions on Internet, but I always get the same mistake:
SQLException: No suitable driver
SQLState: 08001
VendorError: 0MySQL works fine alone or with php.Only thing left me to think is that the installed versions are not compatible for this mysql-connector-java-5.0.4
I don't believe that could be a reason.
Installed versions are:
Apache Tomcat 5.5.20 Server
Apache HTTP Server 2.2.4
PHP 5.2.0
MySQL 5.2
jre 1.5.0_11
jdk1.5.0_11
Apache Tomacat JK2 connector Version: 1.2.20 File Name: mod_jk-apache-2.2.3.so
mysql-connector-java-5.0.4
I also set connector in class path: C:\mysql-connector-java-5.0.4;C:\mysql-connector-java-5.0.4\mysql-connector-java-5.0.4-bin.jar;C:\mysql-connector-java-5.0.4\src\com\mysql\jdbc
For installation I used manulas from:
http://apacheguide.org/jsp.php
http://doc.51windows.net/mysql/?url=/MySQL/ch23s03.html
Here is also a test code in java:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
   public class Connect
       public static void main (String[] args)
           Connection conn = null;
           try {
    conn =
       DriverManager.getConnection("jdbc:mysql://localhost/first_test" +
                                   "user=monty&password=greatsqldb");
    // Do something with the Connection
} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
   }i'm desperate, please help or tell me someone who'll know the answer.
Thank You in advance

hey buddy .. it seems yr code is wrong .. in getconnection () method u should also specify the port ,which u r not doing ...
the default port for MySQL is 3306 ... see below i am giving you a sample code ... its working fine .. and dont forget to put the MySQL driver jar path in to classpath and also copy the jar into common/lib folder of your tomcat ....
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class MySQLConnectionTest {
     public static void main(String[] args) {
new MySQLConnectionTest().connTest();
public void connTest() {
          String tableName = "portfolio"; //change as per setting
          String hostName = "10.81.9.39"; // please change for the target database ip or hostname
          String dbPort = "3306"; //change if not using the default
          String dbName = "tradingsystem"; //change as per the given DB name
          String username = "root"; //change as per setting
          String password = "password"; //change as per setting
          System.out.println("before try");
          Double data=0.0;
     Double data1=0.0;
          try {
Class.forName("org.gjt.mm.mysql.Driver");
               System.out.println("before driver manager");
Connection conn = DriverManager.getConnection("jdbc:mysql://"+hostName+":"+dbPort+"/"+dbName, username, password);
String query1 = "select * from "+tableName+" where User_id='trader1' and Stock_Type='Equity'";
System.out.println("quesry1="+query1);
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(query1);
while(rs1.next())
     System.out.println("hiiiiii for rs1");
     System.out.println(rs1);
     Quantity=(Integer)rs1.getObject(5);
     MarketPrice=(Double) rs1.getObject(8);
     data=Quantity*MarketPrice;
     data1+=data;
     System.out.println("data1="+data1);
     i=0;
rs1.close();
stmt.close();
conn.close();
} catch (ClassNotFoundException e) {
e.printStackTrace(System.err);
} catch (SQLException e) {
e.printStackTrace(System.err);
i hope it will work for u...

What are the different types of analytic techniques possible in SAP HANA with the examples?

Hello Gurus,
Please provide the information on what are the different types of Analytic techniques possible in SAP HANA with examples.
I would want to know in category of Predictive analysis ,Advance statistical analysis ,segmentation analysis ,data reduction techniques and forecast techniques
Which Analytic techniques are possible in SAP HANA?
Thanks and Regards

Hi Sushma,
You can download the user guide here:
http://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CFcQFjAB&url=http%3A%2F%2Fhelp.sap.com%2Fbusinessobject%2Fproduct_guides%2FSBOpa10%2Fen%2Fpa_user_en.pdf&ei=NMgHUOOtIcSziQfqupyeBA&usg=AFQjCNG10eovyZvNOJneT-l6J7fk0KMQ1Q&sig2=l56CSxtyr_heE1WlhfTdZQ
It has a list of the algorithms, which are pretty disappointing, I must say. No Random Forests? No ensembling methods? Given that it's using R algorithms, I must say this is a missed opportunity to beat products like SPSS and SAS at their own game. If SAP were to include this functionality, they would be the only BI vendor capable of having a serious predictive tool integrated with the rest of the platform.... but this looks pretty weak.
I can only hope a later release will remedy this - or maybe the SDK will allow me to create what I need.
As things stand, I could built a random forest using this tool, but I would have to use a lot of hardcoded SQL to make it happen. And if I wanted to go down that road, I could use the algorithms that come with the Microsoft/Oracle software.
Please let me be wrong........

Trouble in a SAP system with load balancing

Hello masters:
I had a trouble with workitems that came from a SAP system with load balancing. They doesn't receive the workitem ID in the UWL.
I created another system in the portal as a "dedicated application server", and made the necessary configuration in order to replace the first one, and then my workitems worked fine.
However, I would like to know what appened with the first system created as "system with load balancing". Why this system didn´t pass the workitem ID to the application (web dynpro abap) that execute the workitems?
Thank you.

I hope there was some missing configuration in the first case which was not replicating the workitem from SAP Inbox to UWL.
Thanks

JDeveloper 10.1.2 with MySQL and PostgreSQL

I'm testing JDeveloper 10.1.2 business components with mysql or postgresql because my company needs to connect also to these non-oracle DBs. ADF suits our developement needs, in speed and functionalities; anyway to make it our main developement system we need it to be compatible.
I made three tests and they were all disappointing.
At first, I installed MySQL 4.0 on my windows machine. I used the stable Connector/J 3.1
and then MySQL Connector/J 3.0, but in both cases JDeveloper had a strange behaviour: I can make the connection, I can navigate correctly through all tables in the connection-navigator, I see all the column names etc... Anyway, as I try to build a "new Entity Object" from a table, there are no available table properties, like if the table had no columns.
In this forum I only found documentation about rowid problems with mysql, but nothing about Entity Object wizard issues.
Then I switched to PostgreSQL. I installed it locally, so I had to choose the 8.01 since I'm on a windows machine. JDBC driver: postgresql-8.0-310 jdbc3
The developement test phase went ok, it is possible to use this DB just as if it was a Oracle, all the business components wizards works perfectly.
The problem is at runtime, unfortunately. I built a simple datapage on the struts-config diagram and I dragged on it a "read-only table" from the data control palette.
As I run the application, the embedded OC4J immediately returns this error:
oracle.jbo.JboException: JBO-29000: JBO-29000: JBO-29000: JBO-26061: Errore durante lapertura della connessione JDBC.
at oracle.jbo.JboException.<init>(JboException.java:343)
(in english: Error during JDBC connection)
There are no other available JDBC drivers for JVM 1.4x so I see no solution...
I also tried to connect to an older PostgresSQL with its (older) JDBC but I get same the result.
Anyone can help? Is it a JDev 10.1.2 issue?

Hi Paolo.
I'm also doing such tests.
I did not ran into these problems because I created the busisness componentes using an Oracle connection first.
After that, I switched the datatype of the table columns in the entity object to meet the SQL92 criteria ( like changing NUMBER(n) to INTEGER ).
And then, I switched the connection to the postgreSQL or MySQL. This worked fine for me.
But, the other big problem you will face is related to updating records using postgreSQL connection.
Please see my post "Problem updating records using BC4J with foreign data sources" Problem updating records using BC4J with foreign data sources
It would by fine if we help each other to solve this problems.
Thanks

SAP APO with SAP R/3 integration

Hi All,
From a technical perspective, what is it that a developer should know to work on SAP APO with SAP R/3 integration. Kindly elaborate on this if you can...
Thanks in advance.
Marvin
Edited by: Marvin Jones on Feb 3, 2008 5:09 AM

Standard APO and R/3 CIF integration does not need additional ABAP coding.
However if you are going to enhance any master or transaction data while transfer via CIF using BADI or User-exits then good amount of ABAP expertise is required.
Per my understanding USer-exits are classical ABAP while BADI are Object-oriented.
While I cannot comment if there will be "immense" amount of coding to be done but CIF user exits remain a critical component of any implementation. Its not the "amount" but "complexity" - need to understand the source system and target system behaiour and then accordingly modify, that matters.
Thumbrule - if its master data modification then its simple. If its transaction data modification then its can become quite complex.
Hope this helps.

Java with MYSQL in Linux

i am using JSP in Linux Platform. when i connected to mysql with mysql driver for odbc by using the following code,
import java.sql.*;
public class TestMysql
public static void main(String args[]) {

          String connStr = "jdbc:mysql://localhost/test?user=root&password=mysql";
          Class.forName( "com.mysql.jdbc.Driver" ).newInstance();
          System.out.println("OK");
          con = DriverManager.getConnection( connStr );
          System.out.println("Again OK");
catch( Exception x )
x.printStackTrace();
i got the following exception

i have the database, hello.
The same code works well in Windows, But in Linux, the above exception.
By using the username root and password mysql , i can connect to mysql directly from the mysql prompt.
Pls help me..
I have already put the query 'access denied problem in Mysql' some day before. from the reply, i made some changes in user table(ie. set the password for [email protected].).After this change, this new Exception came..
The structure of my mysql.user table is
#     host                         user          password
1     localhost                    root          68d4f47c49a579c9
2     localhost.localdomain          root          68d4f47c49a579c9
3     localhost.localdomain
4     localhost
Pls help me.

Well, at least the trace tells me that this issue is to be tracked back to the core of the MySQL JDBC driver and the Linux's implementation of JVM. It might be worth the effort to post this issue at their website/forum/issuetracker. It might also be worth the effort to tryout the newer MySQL JDBC driver 5.1, as it is written specific for JDK 6.0 (while MySQL JDBC driver 5.0 is targeted at JDK 5.0).

Setting up testing server with MySQL

I am just migrating to the MacBook from an older iMac G5. I was running PHP with MySQL 4.1.15. I just downloaded the PHP 5.2.2 and need to know which version of MySQL will run with it on my MacBook. Any help, please, especially if you are using Dreamweaver and have migrated to CS3. Thanks, Jay

Hi
I am successfully running MySQL 5.0.37 with PHP 5.2.1. (I don't use Dreamweaver or CS3 though.)

Hi Gurus, need help

Clob mapping not working with mysql

Hi,
I have an application that i'm running with MySQL and Oracle at the same
time. At some point, i need to use a 'clob' mapping. When i do this, it
just works fine with oracle but it fails with mysql. i have the exception:
Field "com.ennov.prisma.api.document.jdo.AbstractDocumentPO.description"
is mapped as a clob, but should be represented as a different mapping.
If the field is a string and you would like to force it to map as a
clob, add an extension to its field metadata with a key of "jdbc-size"
and a value of
-1.[com.ennov.prisma.api.document.jdo.AbstractDocumentPO.description]
     at kodo.jdbc.meta.Mappings.invalidMapping(Mappings.java:132)
     at kodo.jdbc.meta.Mappings.invalidMapping(Mappings.java:118)
     at
kodo.jdbc.meta.ClobFieldMapping.fromMappingInfo(ClobFieldMapping.java:46)
if i use a value mapping, it works with MySQL but fails with Oracle (I
have sql error because a clob is used in a distinct select).
In the manual, it is written "Note that some databases can support
string of unlimited length without using a CLOB; when this is the case
the mapping tool will install a value mapping in favor of
this mapping.". So apparently, this is not the case with MySQLDictionary.
To solve my problem and have my code working with both databases, i had
to extend the MySQLDictionary and overwrite the replaceFieldMapping
method in order to replace the clob mapping by a value mapping at
runtime but i don't feel confident to do this kind of modifications by
mysel and would expect this behaviour to be solved quite soon.
Thanks for your help since this problem is urgent for us,

Laurent-
The best solution would probably be to just have separate mappings for
the MySQL and Oracle databases. The easiest way to accomplish this would
be to have a separate setting for each of the databases. E.g.:
kodo.jdbc.meta.MappingFactory: file(SingleFile=true, FileName=oracle.mapping)
kodo.jdbc.meta.MappingFactory: file(SingleFile=true, FileName=mysql.mapping)
That way, you can use a clob mapping for Oracle, and a normal value
mapping for MySQL (since MySQL doesn't need to use the CLOB mapping, and
it isn't very efficient).
For more details on this, see:
http://docs.solarmetric.com/manual.html#ref_guide_mapping_factory
Another solution is to just stick with your custom extension of the
MySQLDictionary, which is a perfectly valid way of having special CLOB
handling in MySQL. Note, though, that CLOB handling is less efficient
than VARCHAR handling, so it should be a mapping of last resort, and
there isn't any need to use it in MySQL.
