Rules are defined using XML and SQL and can have complex conditions using conjunctions and disjunctions, and specify a set of events, time, and non-occurrence of events with or without a deadline. It stores intermediate results to quickly evaluate the next event in a long running composite event (an event made up of two or more simple events). It can evaluate events using data from the application and from database tables. It enables developers to create applications that process and respond to events of any complexity using rules and policies defined in the database. Rules Manager is a new feature of Oracle Database 10 g Release 2. In Release 2, the line length limit is increased to 32,767 bytes and the overall limit is removed altogether. When using SQL*Plus, most programmers are regularly caught by the small default overall limit and sometimes by the current 1,000,000 maximum overall limit. PL/SQL programmers frequently use DBMS_OUTPUT and, in Oracle Database 10 g Release 1 and earlier, were constrained by the 255 byte limit. In this case, NULL means "unlimited." SQL*Plus, through the SET SERVEROUTPUT ON command, enables you to take advantage of the new "unlimited" meaning. The procedure DBMS_OUTPUT.ENABLE (buffer_size integer defaults to 20000) has a new allowed value of NULL for the buffer_size. This determines the maximum line size that can be written by the DBMS_OUTPUT.PUT and DBMS_OUTPUT.PUT_LINE procedures. Previously, the VARCHAR2 constraint was 255 bytes.
The declaration of the package type DBMS_OUTPUT.CHARARR is enhanced to support the increased maximum of 32,767 bytes.

This new feature allows custom code generated by shipped vendor code to be obfuscated.摹.1.5.3 Relaxation of Line Length and Overall Limits for the DBMS_OUTPUT PL/SQL Package The command-line WRAP utility, available in Oracle Database 10 g Release 1 and earlier, allowed the code that a vendor shipped to be obfuscated. This is critical when an installed product generates new PL/SQL units, for example as part of a customization process, and when the generated code embodies methods that the product vendor considers to be valuable intellectual property. This feature allows the text of a PL/SQL unit that is created dynamically to be obfuscated. The CREATE_WRAPPED command is a shortcut for and has the same semantics as the EXECUTE IMMEDIATE DBMS_DDL.WRAP (input) command. The obfuscated representation is identical to what is produced if the same CREATE or REPLACE command is processed with the command-line WRAP utility. The command-line WRAP utility takes a plain text CREATE or REPLACE command that specifies creation of a PL/SQL unit and returns a CREATE or REPLACE command where the text of the PL/SQL unit has been obfuscated. The existing DBMS_DDL supplied package is enhanced with two new subprograms.
