TechTip: Saving Spool Files to Disk--An Alternate Method for V4R5

I have a method for saving spool files to disk that can handle all files, not just *SCS files. In the current era, when graphical files are growing in importance, this might be a good solution for some shops. I use the undocumented IBM APIs named QSPGETF and QSPPUTF. These create mirror images of the spool file data files in flat files with a record length of 4083.

Below is the source code for GETSF and PUTSF. GETSF calls program QSPGETF in QSYS, while command PUTSF calls program QSPPUTF in QSYS. GETSF transfers the spool file into a physical file. You have to build the physical file first as a 4083 byte file with level checking turned off. Use Create Physical File (CRTPF) to build the file:

CRTPF FILE(mylib/myfile) RCDLEN(4083) LVLCHK(*NO)

NOTE: These commands work fine on a V4R5 system, but there is a problem under V5R1. Under V5R1, the spool number is a six-digit number, so the command must be modified accordingly.

  • 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:
