TechTalk: Keeping Your Message Files Under Contro

The AS/400 creates a message queue for each display device and user on the system. These message queues can grow in size if the user does not clear received messages. The program, MSG00CL, and two other associated programs, MSG01CL and MSG01, will save the messages of each message queue to a file and then will clear the queue.

The CL program MSG00CL uses the DSPOBJD command to create a file of all type of *MSGQ objects within the library list. The program reads the created file and will call MSG01CL to process each message queue. Program MSG01CL is called using the message queue and message queue library as parameters. MSG01CL will create a file (WRKF) in the current library (if the file does not exist), and will receive the messages from the top of the message queue, removing each message so the next message becomes the top message. For each message, a call is made to an RPG program (MSG01) with the message text, message queue library, and message queue as parameters. The RPG program writes each message to file WRKF. MSG01CL will not process the QHST message queue or message queues that are allocated to other users. Running the CLRMSGQ command after all messages have been removed reduces the size of the queue.

The program MSG01CL can be called from the command line or from any other program using the message queue and library as parameters.

  • SB Profound WP 5539More than ever, there is a demand for IT to deliver innovation. Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects. The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the company are not aligned with the current IT environment.

  • SB HelpSystems ROBOT Generic IBM announced the E1080 servers using the latest Power10 processor in September 2021. The most powerful processor from IBM to date, Power10 is designed to handle the demands of doing business in today’s high-tech atmosphere, including running cloud applications, supporting big data, and managing AI workloads. But what does Power10 mean for your data center? In this recorded webinar, IBMers Dan Sundt and Dylan Boday join IBM Power Champion Tom Huntington for a discussion on why Power10 technology is the right strategic investment if you run IBM i, AIX, or Linux. In this action-packed hour, Tom will share trends from the IBM i and AIX user communities while Dan and Dylan dive into the tech specs for key hardware, including:

  • SB HelpSystems ROBOT GenericForms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.

  • SB HelpSystems ROBOT GenericIT security is a top priority for businesses around the world, but most IBM i pros don’t know where to begin—and most cybersecurity experts don’t know IBM i. In this session, Robin Tatam explores the business impact of lax IBM i security, the top vulnerabilities putting IBM i at risk, and the steps you can take to protect your organization. If you’re looking to avoid unexpected downtime or corrupted data, you don’t want to miss this session.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
