IT Jungle: The 4 GB Access Path Size Time Bomb

Posted on by Joe Hertvik

time bombFrom my latest IT Jungle article:

The time bomb I’m referring to is the Access path size (ACCPTHSIZ) parameter in some application files. In older versions of the OS/400 operating system (the precursor to the modern IBM i OS), the ACCPTHSIZ parameter was set to *MAX4GB by default. With *MAX4GB files, the maximum file access path size can be no larger than 4 gigabytes (4 GB)…When a *MAX4GB physical or logical file access path size hits the 4 GB limit, the file will stop accepting updates and it will crash your application programs with the dreaded MCH2804 error message.

To find out how to detect and resolve this issue, check out the article by clicking here.
