What is the difference between the different connection strings from JBoss 5 to Oracle 11g R2 -

-

We have a Java application running inside JBoss EAP version 5.1 and up to date we always use standard thin driver Use Oracle for

Oracle 11.2.0.2 After upgrading all our customers to the JDBC driver after further investigation and after downloading all related files from the Oracle site, we have jabs 

 < Code> & lt; Connection-url & gt; Jdbc: oracle: thin: @ ... & lt; / Connection-url & gt; & Lt; Driver category & gt; Oracle.jdbc.driver.OracleDriver & lt; / Driver category & gt; & Lt; Connection-URL & gt; JDBC: Oracle: Thin: @ ... & lt; / Connection-URL & gt; & Lt; Driver category & gt; Oracle.jdbc.pool.OracleDataSource & lt; / Driver category & gt; & Lt; Connection-URL & gt; JDBC: Oracle: Thin: @ ... & lt; / Connection-URL & gt; & Lt; Driver category & gt; Oracle.ucp.UniversalConnectionPool & lt; / Driver category & gt;   
 In the latest JBoss lib directory requires a copy of the UCP.JAR file.  
 The question is: Has anyone experienced different configurations and found better than one else in terms of performance and stability?

 It depends What kind of connection do you want or do you want to set up a pool connection? Normally in the middle level environment you want to use the pool connection to limit the number of connections from your database and also provide good service time.  
  1) Direct connections from database 2) Pool connection to database 3) Connection connected to database, new UCP pool     uses it

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
