Issue/Introduction

I am formatting some new files and am getting errors relating to size. 

CONNECT TO SYSTEM ; 
Status = 0 SQLSTATE = 00000 
FORMAT FILE segment-name.file-name; 
Status = -4 SQLSTATE = 5000B Messages follow: 
DB002252 C-4M352: Function WRITE DDname ddname - I/O error 12 

Command Facility ended with errors 
IEC031I D37-04

What’s causing this?

 

Resolution

The IDMS database file was being allocated with the EXTREQ values in the "Data set name type" field (thus forcing it to be EXTENDED), and 1000 "Secondary tracks." Since IDMS r17.0, DSNTYPE=LARGE is supported for all file types. On the other hand, DSNTYPE=EXTENDED is only allowed for REORG work files. Both LARGE and EXTENDED format files can have more than 65,535 tracks on a single volume.
