What is the procedure for resizing the ARM History file if an out-of-space condition has occurred?

                             
 

If the ARM History file runs out of space and you need to resize it, use the ARMHSTEX sample member in the BMCSAMP library.

//HISTV11  EXEC PGM=IEBDG                                 
//SYSPRINT DD SYSOUT=*                                     
//HISTORY  DD DSN=BMCARM.SSID.HISTORY,DISP=(,CATLG),      
//            UNIT=SYSALLDA,SPACE=(CYL,(7,1)),            
//            DCB=(RECFM=FB,LRECL=216,BLKSIZE=9720)       
//SYSIN    DD *                                           
  DSD OUTPUT=(HISTORY)                                    
  FD NAME=HDR1,LENGTH=01,STARTLOC=02,PICTURE=1,B'3'       
  FD NAME=HDR2,LENGTH=01,STARTLOC=04,PICTURE=3,B'216'     
  CREATE QUANTITY=1,FILL=X'00',NAME=(HDR1,HDR2)           
/*                                                         

Once you have created the new history file using the ARMHSTEX sample member then run IEBGENER to copy the contents from the old history file.

//jobcard
//*
//COPY    EXEC PGM=IEBGENER                        
//SYSPRINT  DD SYSOUT=*                            
//SYSUT1    DD DISP=SHR,                           
//          DSN=BMCARM.ssid.HISTORY.OLD            
//SYSUT2    DD DISP=OLD,                           
//             DSN=BMCARM.ssid.HISTORY             
//SYSIN     DD DUMMY

The history file is ready for use.
