 The DB2 database must be catalogued for a connection like this to work.
 </WRAP>
+==== Building a catalog entry ====
+This is a simple example building a catalogued connection from a windows client to a remote DB2 server running on a machine named adodb-db2.local. The server is running on port 25010. We will add a DSN entry called //**adodb-test**//
+<code>
+db2cli writecfg add -database SAMPLE -host adodb-db2.local -port 25010
+db2cli writecfg add -dsn adodb-test -database SAMPLE -host adodb-db2.local -port 25010
+</code>
+To use this DSN
 <code php>
 include '../adodb/adodb.inc.php';
-$database = 'SAMPLE';
+$dsn = 'adodb-test';
 $user = 'db2inst1';
 $password = 'instance';
 $conn = ADOnewConnection('db2');
-$conn->connect($database, $user, $password);

 ===== Case Sensitivity In Table And Column Names =====
@@ Line 126: / Line 153: @@
 Any table name containing special characters will need to be quoted in all queries.
-==== Using metaCasing with DB2 ====
-When using DB2, it is important to remember that when using [[dictionary:setmetacaseoption|metaCasing]] and having mixed or lowercase table names in the database may mean that tables may become difficult to access if the are not in the same casing convention as to what is normally used.
-Generally, development standards mean that table names in a database are created to a casing standard, for example, all upper-case or lower-case table and column names. In that case, metaCasing will work the same as in other databases, e.g.
-<code php>
-/*
-* Connection to DB2 smple database, accessing a table called ACT
-* Set the casing to lower case
-*/
-$db->setMetaCaseOption($db:METACASE_LOWER);
-$cols = $db->metaColumnNames('ACT');
-print_r($cols);
-/*
- * Prints
-Array(
-  [0] => actno,
-  [1] => actname,
-  [2] => actdesc
-  )
-  */

-<WRAP right info 300px>
-These rules also apply to column naming

-===== The Impact Of METACASE_NATIVE =====
-Setting the metaCasing option to ''METACASE_NATIVE'' has an impact on the entire life cycle of a table, and it's use should be understood.
-==== Creating Tables ====
-Consider the following case-sensitive table name: ''accountTable'', and how it is created and referenced in ADOdb.
-^MetaCase^Created As^SQL Retrieval^Presentation in MetaFunctions^
-|METACASE_UPPER|ACCOUNTTABLE|SELECT FROM ACCOUNTTABLE,accountttable,accountTable etc.|ACCOUNTTABLE|
-|METACASE_LOWER|ACCOUNTTABLE|SELECT FROM ACCOUNTTABLE,accountttable,accountTable etc.|accounttable|
-|METACASE_NATIVE|accountTable|SELECT FROM "accountTable"|accountTable|
-As shown, once a table is created in non-upper case when the metaCasing value is ''METACASE_NATIVE'', it **must always** be retrieved using the same casing, and all SQL operations must quote the table names. The functions [[reference:autoexecute|autoExecute()]],[[reference:getinsertsql|getInsertSql()]], and [[reference:getupdatesql|getUpdateSql()]] will automatically quote table and column names if ''METACASE_NATIVE'' is set. For DB2, this behaviour overrides the ''$quoteFieldnames'' parameter.
