5 Ways to Control Access using Application AdministrationNever heard of Application Administration? Donâ€™t be surprised. Although itâ€™s full of function, itâ€™s one of little-known features of IBM i. Application Administration (or App Admin as itâ€™s commonly called) has been around for a while but the additional features provided in the latest releases as well as recent Technology Releases makes this a feature worth exploring again. Carol Woodbury, President of SkyView Partners, has written a white paper describing how you can use Application Administration (a feature of i Navigator) to control access to various client functions as well as functions available on the IBM i and network features such as ODBC and FTP access.â€¦
5 Winning Strategies to Combat Information OverloadTodayâ€™s businesses must be available 24/7 with fewer people having to manage more complex systems and processes. IT departments receive a constant bombardment of information from a diverse variety of operating systems, business applications, and critical processes and support a complex array of servers and devices running across their entire network. With tight resources and the need to keep costs in check, more and more is expected of IT operational staff to handle this information efficiently. They need to ensure a swift response with appropriate actions, that essential data is received at the right time, prove service levels are maintained, that contingency and high availability strategies are fully operational, and that vital busiâ€¦

PCI and What it means to IBM iWhile one may think that PCI is a thing of the past and that itâ€™s already been implemented, major breaches (most notably of the Target PoS systems) have brought it back into focus. Some retailers are just now understanding how PCI applies to them and other organizations have started to accept credit cards when they didnâ€™t in the past. To refresh everyoneâ€™s memory, hereâ€™s an overview of what PCI means to the IBM i community and what organizations that use an IBM i to store, process or access cardholder data need to be aware of.â€¦
Robot in Modern IBM i EnvironmentsAs hardware and software technologies evolve, so too does the complexity of the data center.IBM i often serves as the backbone for business-critical applications, including ERP packages, leaving other servers to run email, print serving, and the websiteâ€”but users and other computing technologies still draw data from the transactional database on IBM i. Robot systems management solutions have been helping customers manage IBM i operations for over 30 years. This white paper is intended primarily for IT management and attempts to explain, in plain English, the components of modern IBM i environments and how Robot can be deployed to maximize business objectives.

Virus Got You Down?Does a virus have your server down? Perhaps itâ€™s the latest worm, Trojan horse, buffer overflow or denial of service attack thatâ€™s got you or one of your servers down. While one of these bugs may be affecting one or more of your servers in your enterprise, it is highly unlikely that the server affected is a Power server running IBM i. IBM i may be running your core business applications or it may be hosting your website or running Domino. Whatever its function within your enterprise IBM i has remained unaffected by virus and malware attacks. Why is that? Viruses and other ailments spread by infecting a host that is vulnerable. Letâ€™s take a look at how IBM i and the applications running on it can remain unscathed by the viruses and malwarâ€¦
When Management Turns its Back on Security: The Business EffectsIn this white paper we hope to explain why the decision to secure- or not secure â€“ data on the IBM i needs to be a business decision ... not a technical decision.

For decades, RPG has included the ability to have multiple occurrences of a data structure in a program. Multiple occurrence data structures are defined in RPG IV through the use of the OCCURS keyword on the data structure declaration specification. In RPG III, multiple occurrence data structures are specified by placing the number of occurrences in the "From" columns of the Input specification for the data structure.
In RPG IV, the OCCURS keyword is used to set the number of occurrences, while the OCCUR opcode is used to set or extract the current occurrence. The use of the OCCUR opcode is somewhat clumsy in that you can never address the nth occurrence of a data structure without moving the occurrence index to the desired occurrence and then addressing the data structure subfields.
With OS/400 V5R2, multiple occurrence data structures have been deprecated. The new "Data Structures as Arrays" feature allows you to use the DIM keyword to declare a data structure as an array, effectively giving it multiple occurrences. Figure 1 illustrates the use of the DIM keyword being used to declare a data structure as an array.
Figure 1: A data structure being declared as an array
Subscripting a data structure array is similar to subscripting a regular array index; simply enclose the index in parentheses following the data structure name. The array index is followed by a qualified subfield name. This is the subfield being modified or retrieved. In the example that follows, the subfield CUSTNO of the fifth element (occurrence) of the CONTACT data structure is set to 12345.
Only qualified data structures may be declared as an array. Therefore, the data structure must be declared with one of the QUALFIED, LIKEDS, or LIKEREC keywords. Qualification allows the subfields to be manipulated in do loops or the contemporary for loops. In Figure 2, the for loop iterates through each element of the CONTACT data structure array and sets the value of the BALDUE subfield to zero.
Figure 2: Accessing an array data structure's subfields
The V5R2 Data Structure as Arrays feature makes multiple occurrence data structures much more usable. We no longer need to set the occurrence before accessing the subfields of the occurrence we want. We simply use array subscripting, and we are there.
In Figure 3, I illustrate how multiple occurrence data structures are handled in V5R1 and earlier.
Figure 3: Traditional multiple occurrence data structure
In this example, line 1 declares the CONTACT data structure as a multiple occurrence data structure; the OCCURS(20) keyword is used to declare 20 occurrences. Line 9 in this example is identical to that used in the example in Figure 2. Line 10, however, is where the difference is; it uses the OCCUR operation code to set the current occurrence of the data structure. Finally, on line 11, the BALDUE field is set to zero.
Note that since this is not a qualified data structure, the BALDUE field is not qualified to the parent data structure. If the CONTACT data structure listed in Figure 3 had also included the QUALIFIED keyword, then line 11 would have been specified as follows:
The difference in syntax between this example and what is used in Figure 2 is that the data structure is not an array here but is an array in the example in Figure 2. Therefore, the array scripting parentheses are not specified.
A few things to remember:
- Qualified data structures were introduced in OS/400 V5R1.
- Data structures as arrays were introduced in OS/400 V5R2.
- The LIKEREC keyword (an enhancement to qualified data structures) was introduced in OS/400 V5R2.
- The QUALIFIED, LIKEDS, and LIKEREC keywords cause the data structure to be qualified.
- Only Qualified Data Structures may be declared as arrays.
