Snort with mysql [solved]

Hi All,
I relatively new to arch.
Now I want to run snort with mysql support. My log file claims that the default pkg through pacman does not have mysql support enabled.
How do I go about enabling this in a simple way. Is there somewhere where I can obtain the original PKGBUILD so I can tweak that one, or do I have to start from scratch?
Or, am I doing something wrong in the first place?
thanks,
Leon..

You're not doing anything wrong - snort is indeed compiled --without-mysql. You can get the PKGBUILD and associated build files from the CVS link here, or by running abs to acquire the entire Arch package tree.
If you haven't built any Arch packages before, modifying an existing one like this is a good way to start. The relevant wiki articles are highly recommended reading.

Problem with MySQL (SOLVED)

Hello everybody. I have a problem with my MySQL server. Just installed it, ant when i try to start it:

I have a huge problem, it seems I can't login to my own mysql server
mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
The first time I started mysqld I got the same error as above. The script that should create an account stopped. Because of this I didn't set a root password. I think I never set a root password, but somehow mysqld expects one.
Could someone help?
btw: my host in rc.conf is not localhost and it's corresponding with the hostname in /etc/hosts
-edit--
I just tried these steps: http://dev.mysql.com/doc/refman/5.0/en/ … sions-unix
But this also didn't work
--edit2--
Seems that there isn't a root account at all!

This is currently listed as a feature request. Although nothing has happened yet. Also the current PKGBUILD does not build because of broken URL's.

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

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 Czinczenheim

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.

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.

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;

   public class Connect
       public static void main (String[] args)
           Connection conn = null;

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 ....

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).

can any one place some example illustrating the steps involving.thanx

Hi smogura,
Thanks for the message. Ok I did as you told. I believe I went to the right place:
Resource->JDBC Connection pools. However I wasn't sure how exactly to go about setting connection pools,
so I went to the web and did a search and I managed to get hold of this
website:http://www.albeesonline.com/blog/2008/08/06/creating-and-configuring-a-mysql-datasource-in-
glassfish-application-server/
I followed from steps 4 onwards. However at step 14, I did not get a sucesfull ping. The values I used are as follows:
General:
Name:               MySQL
Datasource Classname:     com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource

I am not sure what is wrong, by the way, I am using Glassfish V3 that comes bundled with netbeans. Any idea what's wrong or missing? Thanks

Reconnect policy with MySQL failing because of autoCommit error

This related to this issue, but I didn't see any responses to it: Reconnecting a dead connection from a UnitOfWork commit - Autocommit error
I'm testing with MySQL 4.1 and I have a reconnect policy that does the following (I believe this is a pretty standard approach):
session.setExceptionHandler( new ExceptionHandler() {
public Object handleException(RuntimeException exception) {
if (exception instanceof DatabaseException) {
dbex.getAccessor().reestablishConnection(dbex.getSession());
However, when it reestablishes the connection (and I have traced this and can verify that this code is executing and a reconnect is performed), I get the following error for any updates:
Internal Exception: java.sql.SQLException: Can't call rollback when autocommit=trueError Code: 0
at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:277)
at oracle.toplink.internal.databaseaccess.DatabaseAccessor.basicRollbackTransaction(DatabaseAccessor.java:1090)
at oracle.toplink.internal.databaseaccess.DatasourceAccessor.rollbackTransaction(DatasourceAccessor.java:486)
at oracle.toplink.internal.databaseaccess.DatabaseAccessor.rollbackTransaction(DatabaseAccessor.java:1075)
at oracle.toplink.publicinterface.Session.basicRollbackTransaction(Session.java:377)
I only have this problem with the MySQL JDBC drivers. I can continue to read normally, but I can't perform any transactions.
This isn't so much of a question about MySQL specifically, but rather a question about how reestablishConnection() connects to the database differently from my initial login using DatabaseLogin. Obviously, I don't have this error connecting normally. I only get it after a reconnect is applied.
Specific questions are: Is there another handler I can add to ensure JDBC Connections returned by ServerSession are always setAutoCommit(false)? Am I reestablishing the JDBC connections incorrectly?
Nate

Nate,
This does appear to be MySQL JDBC specific but is most likely related to a general issue.
When the connection drops and you receive the notification through the exception handler I would typically recommend looking at the session in us (isUnitOfWork) or the query type (isWriteObjectQuery) to see if the operation that failed was involved in a transaction (UnitOfWork commit).
In these transaction cases you need to do more then just re-connect and retry. You need to ensure after reconnection that an application exception is raised so the UnitOfWork operation(s) can be retried completely. I would simply add to this case to ensure that the JDBC connection is put back in a state where it can be managed properly.
There is no special operation or any case I know of where any special auto-commit needs to be set on a connection after it has dropped and before it is re-connected.

ExecuteQuery() error with MySQL

I have already followed all the steps recommended by OTN to create a connection with MySQL (most up-to-date files) in JDeveloper 10g. It works fine except when I try to find a view and execute a query using an Application Module in a jsp:
ApplicationModule appMod = appMod.getGenericAppMod();
ViewObject voTabEmployee = appMod.findViewObject("TabEmployee");
voTabEmployee.executeQuery();
It works ok when connected to Oracle DB but it raises the following exception when I move Business Components to a MySQL connection, exactly as recommended:
java.lang.ClassCastException: com.mysql.jdbc.ServerPreparedStatement
Any help would be highly appreciated.
Marcio

Hi Marcio
The ApplicationModule that you create in your source (utilApp.java) is created using the default configuration that uses the OracleSQLBuilder as the default SQLBuilder (configured to work with Oracle Databases). Thus, when you use MySQL or any other database (and I confirmed this using SQLServer), a ClassCastException is thrown.
Instead of using the following lines:
Context ic = new InitialContext(env);
String theAMDefName = "mysysjcom.MySysJComModule";
ApplicationModuleHome home = (ApplicationModuleHome) ic.lookup(theAMDefName);
ApplicationModule appMod = home.create();
appMod.getTransaction().connectToDataSource(null, "jdbc/MYSYSJCOMCoreDS", false);
can you use the following lines:?
Context ic = new InitialContext(env);
String theAMDefName = "mysysjcom.MySysJComModule";
ApplicationModule appMod = Configuration.createRootApplicationModule(theAMDefName, <config_name>);
ic.lookup(theAMDefName);
I got your sample working with the above change
This will ensure that you are using the same configuration that has the SQLBuilder correctly set to your Database type
