BTS Trace

The BTS trace feature logs DL/I API calls and parameters issued by an IMS application. You enable BTS trace from JCL. When JCL SSTM support is enabled, you can use the BTS trace feature to also trace IMS transactions, CICS transactions, and batch programs from CRUN.

Enable BTS Trace

You enable BTS trace from JCL using the following DD specifications:

IMSTRACE

Defines the output data set for the BTS trace. SYSOUT=* directs BTS output to the job. You can also direct output to a data file by specifying DCB=(RECFM=LSEQ,LRECL=80,DSORG=PS).

BTSCONFG

Enables control of BTS trace output options, and takes the following keywords:

`SSA`	Include segment search arguments, if any
PCB	Include the PCB area
PCBHELP	Include help text in the trace for invalid SSAs (AJ DL/I status code)
`IOAREA`	Include input-output buffer
STATS	Include call statistics
`TIMES`	Include call timings for performance measurement
DIAG	Include detailed diagnostic information
`LISTFILE`	In addition to the specified output data set, write BTS trace output to a compressed file named BTS-`nnn`.LST, where `nnn` is the process ID in decimal

These specifications apply to the current job step only, and override any BTS trace flags stored in the IMSCONFG.DAT configuration file.

Examples

Sample JCL

This sample JCL enables BTS trace in an IVP program named DEMO001B:

//S01       EXEC PGM=DFSRRC00,REGION=4M,
//          PARM='BMP,DEMO001B,DEMO001T,,,,,,,,,CDLI,,N,N'
//REPORT1   DD SYSOUT=*
//IMSERR    DD SYSOUT=*
//PRINTDD   DD SYSOUT=*
//SYSOUT    DD SYSOUT=*
//SYSPRINT  DD SYSOUT=*
//IMSTRACE  DD SYSOUT=*
//BTSCONFG  DD *
SSA
PCB
IOAREA
/* 
//

Sample BTS output

This sample BTS output is from the DEMO001B program, and shows the DL/I call function, SSAs, PCB, and I/O area:
