SQL indexes and native I/O – no contradiction
Native I/O is widely used in RPG and COBOL programs for getting access to the data stored in the database. Data access is mostly performed with the help of data description specifications (DDS) keyed physical and logical files. Unfortunately DDS is an outdated technology, while all future development regarding the database and data access is only integrated into SQL. For profiting from the new indexing technologies in release 6.1, native I/O does not need to be replaced with embedded SQL. SQL indexes can be used with native I/O like any keyed logical file. Moreover, the enhanced indexing technologies could first be used with native I/O while the SQL query optimizer could only partially profit from these enhancements.This article explains how SQL indexes can be used in conjunction with native I/O and how native I/O can profit from the enhanced indexing technologies.

FTP and Telnet are two examples of core networking applications. Vendor applications that are coded to a System SSL programming interface can use the new support with code changes.

Build and install ICU on IBM i
International Components for Unicode (ICU) plays a key role in developing a globalized product. ICU is supported by option 39 of the base IBM i, however, you may want to build your customized version of ICU and include it together with your product. Building ICU on IBM i is as easy as building it on other platforms, but you may still experience some problems due to the platform difference. To avoid those problems, some environment variables should be set correctly. In this article, we introduce the steps on how to build ICU on IBM i and how to fix the potential problems when building it.

System versus SQL name, Part 2: Accessing database objects
When running SQL statements, you can run them either using system or SQL naming convention. The previous article was focused on the differences in ownership and access authorities when creating database objects with the SQL and system naming convention. This article examines the behavior differences with system and SQL naming when accessing tables and views as well as stored procedures and user-defined functions (UDFs), focusing mainly on the different behaviors when using unqualified references to those objects.

Using the RTVDSKINF command to avoid disk storage disasters on IBM i
Despite over 20 years of IBM introducing larger and faster technology into the IBM i operating system, there are still data file limits that you must observe. One such limit is the maximum number of objects in a library. Hitting that limit compromises your backup policy and causes unnerving delays in the simplest procedures. How can you warn yourself of this impending crisis? Fortunately, the tools you need have been available in the operating system all along. This article discusses how you can use the Retrieve Disk Information (RTVDSKINF) command to gather information about the libraries in IBM i and create listings that can track libraries with excessive objects. The article also provides tips for creating queries to analyze the data from the RTVDSKINF procedure.

Test drive SSO
This article shows you how to set up Single Sign On (SSO) on the IBM i platform. SSO allows you to sign on to your primary workstation and then access other systems and applications without having to sign on again. You'll learn how to set up all the required software and how to verify each step has completed properly before continuing to the next. Soon you'll be using 5250 Emulation, NetServer, IBM System i Navigator, IBM WebSphere® Application Server and the Java™ Toolbox to access your IBM i system without having to sign on to each. Please note that there are several different components that all have to work together, so the time required to implement SSO will depend on how comfortable you are with each of the components, but generally expect to spend several days.

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.

Freeing your IBM i libraries and files
Long time users of IBM Power Systems hardware may find themselves stuck with tape drives that are nearing obsolescence. Quarter-inch cartridges, 8mm, and reel-to-reel tape drives don't have much of a place in the IBM POWER6 and POWER7 world. Learn how you can use disk space to back up IBM i objects in a format that can be transmitted to any other IBM i system without using a common tape media, saving objects to save files or virtual tapes, and then using FTP to transmit them to another IBM i system or Windows disk drive.

Hierarchical Queries with DB2 Connect By
According to the SQL Standard, hierarchical (e.g. organization charts, bill of materials) or bi-directional data (e.g. flight connections) can be evaluated by using a recursive common table expression (RCTE). RCTEs were delivered with release V5R4 of DB2 for i. Other databases such as Oracle use a non-standard method for querying data called hierarchical query clause. To allow maximum portability the hierarchical query clause is introduced with PTF SF99701 Version 9 in DB2 for i. This article will explain the syntax of the hierarchical query clause, how it can be implemented in composition with new operators, pseudo columns and special scalar functions.
