Issue/Introduction

Bundl and LSERV are installed in multiple LPARs.

This article describes how to identify which Bundl VSAM files are being serviced by which LSERV task. Specifically, how to identify the NAME of the Bundl "DPMFBSF" file and which LSERV task is servicing it.

Environment

Release : 5.0

Resolution

To identify the DPMFBSF file for a particular Bundl system, you will need to know which LSERV task is servicing that Bundl's VSAM files. You will also need to know the correct SSN$ and DDN$ values for LSERV and the Bundl VSAM files.  

If you are not sure what the SSNAME (SSN$) value is for the LSERV task that is servicing the Bundl VSAM files and/or you are not sure of the DDN$ value being used, do a mainframe logon to Bundl and on the primary options screen, in the COMMAND line, type SYSID and hit the enter key. The values for SSN$ and DDN$ being used for the Bundl region that you have logged on to will be shown in the TOP LEFT corner of the screen. Example:

LSRV DPMF------------- CA-BUNDL: Primary Options Menu

In the above example, the value for SSN$ is 'LSRV' and the value for DDN$ is 'DPMF'                                         

The LSERV started task is the STC that executes PGM=LDMMAIN. This task controls all I/O into and out of the Bundl VSAM files. Look at any/all LSERV tasks that are running on the systems to see what specific Bundl files each task is servicing.

After selecting the LSERV task, identify that LSERV task's SSN$ value by doing a FIND on the SSNAME parameter. Example:

//L1BUND50  PROC SSNAME=LSRV,MEMBER=LDMPRM50 - (In this example, the SSN$ value for this LSERV task is 'LSRV')

To identify which Bundl BSF file(s) are being serviced by this particular LSERV task, do another FIND on "DPMFBSF" where you will see messages similar to the following, which identify the name of the Bundl BSF file being serviced: 

LDM0090I ADDFILE ????BSF <hlq>.BUNDL.R50.DPMFBSF POOL(1),
LDM0090I                 OPT(MINLEN=446)
LDM0503I ????BSF . successfully added 

In the above example, the value that you see in place of ???? above will be the DDN$ value from the Bundl 'SYSID' command in above. Also, in this example, the actual NAME of the Bundl BSF file is "<hlq>.BUNDL.R50.DPMFBSF". This is the name to look for in TSO.
