Solution

SYS1.PARMLIB Member:

TRACE=IOP,SIOP,CCWP,PCI,SSCHP,CSCH,MSCH,HSCH

SSCH=(0D9E)

IO=SIO=(0D9E)

CCW=(SI,CCWN=150,DATA=256,IOSB)

END

SYS1.PROCLIB Member:

//GTFSL PROC

//*

//IEFPROC EXEC PGM=AHLGTF,

// ACCT=505301CIMA,

// DPRTY=(15,15),

// PARM=('TIME=YES',NP),

// REGION=3000K

//SYSUDUMP DD SYSOUT=1,CHARS=ST15

//IEFRDER DD DSNAME=hlq.GTF.TRACED,DISP=SHR

//SYSLIB DD DSNAME=SYS1.PARMLIB(GTFPRMS),DISP=SHR

IEFRDER is a preallocated trace data set and should be very large, hundreds of cylinders.

DCB=(LRECL=4092,BLKSIZE=4095,RECFM=VB)

You cause the following console command:

S gtftrc.gtrc

When you want to stop the GTF Trace issue:

P gtrc
