Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix®.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.

SQL Packages ExtensionThe SQL packages extension provides SPL routines that you can use in an application that is compatible with database servers other than HCL OneDB™.
DBMS_RANDOM packageThe DBMS_RANDOM package provides a mechanism for generating random numbers. Use the INITIALIZE procedure to set the seed value, which is used by the random number generator to generate the numbers.

DBMS_RANDOM package

The DBMS_RANDOM package provides a mechanism for generating random numbers. Use the INITIALIZE procedure to set the seed value, which is used by the random number generator to generate the numbers.

After enough repetitions, it is possible that some of the generated values will repeat. To reduce the possibility of repeating values, periodically change the seed value by using the SEED procedure.

The DBMS_RANDOM package includes the following system-defined routines and types.

Table 1. System-defined routines available in the DBMS_RANDOM package
Routine name	Description
INITIALIZE procedure	Initializes the package with the specified integer seed value. Optional.
SEED procedure	Resets the seed with the specified integer value.
RANDOM function	Uses the existing seed value to return a random integer.
TERMINATE procedure	Terminates the package by resetting the seed value to `0`. Optional.
