Looking at the past few releases it becomes evident that IBM for some time now has been focusing on delivering more new DB2 for i Services, rather than adding to the system API repository. The DB2 for i Services offer access to a variety of information through system-provided SQL views, procedures, and functions, which in […]
Anyone who has been programming APIs for some time will probably be familiar with user space objects. The original list APIs, such as the List Objects (QUSLOBJ) or the List Job (QUSLJOB) API, almost all return the requested information to a user space. A user space basically is a chunk of storage of up to […]
Some time ago I wrote the WRKUSRAUD, ADDUSRAUD and RMVUSRAUD commands to help me manage user profiles object and user action audit requirements. Recently I needed to perform similar updates to user profiles’ special authority setting, and therefore found it useful to create similar commands for the purpose of adding and removing special authority to […]
Back in time the _CIPHER MI instruction was the only immediately available function to produce an MD5 (Message Digest) or SHA-1 (Secure Hash Algorithm) hash value. Now that the SHA-1 algorithm has been deprecated, it appears that the _CIPHER MI instruction does not support the SHA-256 hash algorithm. IBM probably decided to focus their effort […]
I had come across the term Workload Capping Groups (WLC) a couple of times before I actually found out what it was about – and exactly how workload capping groups could be taken advantage of. I had noticed a new Workload Capping Group (WLCGRP) attribute on the Change Job (CHGJOB command) at one point. The […]
When I was planning the WRKUSRAUD command design some time ago, I found out that IBM with release 6.1 added 18 new user audit values to the 13 original ones. As a consequence of this enlightenment – and due to the circumstance that I was planning to integrate the UPDUSRAUD, ADDUSRAUD and RMVUSRAUD commands in […]
I think the most common reason for investigating a server’s SSL connections and the protocol version associated with these connections is tightly related to audit and compliance. The type of encryption applied to your SSL traffic can be more or less vulnerable, depending on the cipher algorithms involved. In general you have two considerations to […]
As I was doing additional research on the IDS (Intrusion Detection System) topic, I came across the “Control Intrusion Detection and Prevention API”. This API (Application Programming Interface) is provided by IBM to allow you to perform some vital IDS management routines. I’ve wrapped the API up in a new CL command CTLIDS (Control Intrusion […]
A Swiss Army knife provides a variety of useful tools all in one place. In this installment of APIs by Example, I’ll present a similar toolset that helps database programmers get the job done efficiently: the Work with Database Files (WRKDBF2) command. The WRKDBF2 command is the result of me performing repetitive tasks against all […]
Manage local, LAN, and remote output queue writers with one command. In the previous installment of APIs by Example, “Work Management APIs: Keeping an Eye on Job Activity,” I noted that the beauty of APIs is that they give you the opportunity to accommodate specific requirements as challenges arise. The Work with Printers (WRKPRT) command […]
