Using the SNMP GetBulk request for data retrieval
Simple Network Management Protocol (SNMP) provides a system or network management application with the ability to gather information about network devices and to monitor them. To accomplish this, SNMP defines a set of operations for retrieving and setting data as well as monitoring for conditions being reported by the managed devices. One of these operations is GetBulk, which provides an application with the ability to easily retrieve a large amount of data with a single request. This can be particularly useful when retrieving information from the standard SNMP tables. This article describes how to use a new GetBulk API for retrieving data from a table and other new functions recently added to the SNMP support on IBM i.

System versus SQL name, Part 1: Object authority and privileges for SQL database objects
When executing SQL statements you can run them either using System or SQL Naming. The System Naming conventions follow the traditional methods used on IBM i systems such as library support. The SQL Naming mode on the other hand is defined in the SQL Standard and used by all other databases. When asking what is the difference between SQL and System Naming, you will normally get the answer, schema and object are either separated with a slash or a period. However there are many more differences especially with regard to the access authority and ownership of database objects created either using SQL or System Naming. This article will show the differences between SQL and System Naming primarily focusing on how the ownerships and access authorities vary when creating DB2 for i database objects (such as tables, stored procedures or triggers) with the two naming conventions.
