IBM i 7.2 Enhancements for Permanent Storage Tracking

In the 7.2 release, IBM made many changes to improve temporary storage tracking. I’ve written about these enhancements in IBM i 7.2 Improved Temporary Storage Tracking Part 1Part2, and Part 3 blogs. You may also want to reread the blog, Understanding Disk Space Usage, which reviews IBM i temporary and permanent storage concepts. 

In addition to improving temporary storage tracking, IBM also made some improvements for permanent storage tracking in the 7.2 release. This post reviews three of them. 


Sending a Spooled File via TCP When Working With Spooled Files

You can work with spooled files through a variety of command interfaces: Work with Spooled Files (WRKSPLF), Work with Output Queue (WRKOUTQ), and Work with Job (WKRJOB) option 4 (aka WRKJOB OPTION(*SPLF)). These interfaces have option 1=Send, which can be used to send spooled files to another system; this send option invokes Send Network Spooled File (SNDNETSPLF).


Secure my Telnet Remote Terminal Session

IBM i has had the capability to utilize Secure Sockets Layer (SSL) and Transport Security Layer (TLS) to secure the Telnet server for several releases. This feature was only for the server, until last year. Now instead of needing third-party Telnet clients to connect to your IBM i over TLS/SSL, you can use the native Telnet client. This is a necessary enhancement for customers who need to completely disable unsecure Telnet terminal sessions on port 23 on their IBM i servers. Starting with IBM i 5.4, it’s possible to use SSL with the Telnet client (TELNET or STRTCPTELN CL command) from IBM i to any SSL Telnet server.
