1. Download file for the appropriate z/OS or OS/390 Release.
2. Install the utility.

Downloading DUMPWRITE

The two binary files for DUMPWRITE are available via anonymous ftp to ftp.software.ibm.com in directory s390/mvs/tools/dmpwrite. Click on one of the options below for detailed instructions how to download DUMPWRITE directly to the z/OS or OS/390 host, or via the workstation.

• Downloading directly to your z/OS or OS/390 Host:
  • Click here for instructions using file transfer protocol from a TSO command line.
  • Click here for instructions on submitting a Batch JOB.
• Downloading through the workstation:
  • Click here for instructions to download directly from your browser to your workstation.
  • Click here for instructions to use anonymous file transfer protocol (ftp) to your workstation.
  Once downloaded to the workstation, the file must be uploaded to the z/OS or OS/390 Host system:

Installing DUMPWRITE

• If DMPWRITE was retrieved, the following messages will be displayed :

  INMR901I Dataset PTFLCG.F09.MIGLIB0 from NHAN on PLPSC
  INMR902I Members: DMPWRITE
  INMR906A Enter restore parameters or 'DELETE' or 'END' +
  

  Since the originating dataset PTFLCG.F09.MIGLIB0 was allocated with U,0,27998, you can either receive DMPWRITE into an existing PDS which has identical attributes or place it into a new PDS by itself. To place it into an existing PDS, reply to INMR906A with the PDS name and/or with a member name (i.e. DA(PACKLIB) or DA(PACKLIB(DMPWRITE)). To place it into a new PDS by itself, reply to INMR906A with the PDS name. (i.e. DA(DMPEXTRCT.LOAD))

• If DMPWRIT2 was retrieved, the following messages will be displayed :

  INMR901I Dataset PTFLCG.G10.MIGLIB from NHAN on PLPSC
  INMR902I Members: DMPWRITE,DMPWRIT2
  INMR906A Enter restore parameters or 'DELETE' or 'END' +
  

  Since the originating dataset PTFLCG.G10.MIGLIB was allocated with U,0,27998, you can either receive these two members into an existing PDS which has identical attributes or place them into a new PDS by themselves. To place them in an existing PDS you should reply to INMR906A with the PDS name, i.e. DA(PACKLIB) (because there are two members in this dataset, you cannot specify the member names). To place them into a new PDS by themselves, reply to message INMR906A with the new PDS name (i.e. DA(DMPEXTRCT.LOAD).

Using DUMPWRITE

Once DUMPWRITE (DMPWRITE or DMPWRIT2) is installed, you need to utilize a steplib, TSOLIB or LNKLSTxx to make this dataset accessible on the system.

Once the DUMPWRITE program is in the normal module serach list, an IPCS user can issue the command VERBX DMPWRITE against the SADUMP to identify whether any captured SVC dumps exist. DMPWRITE will display the dump titles from all of the captured dumps found in the SADUMP.

If one of the captured dumps is needed, the following steps should be used to extract the dump:

1. Allocate a dataset with RECFM=FB LRECL=4160 BLKSIZE=4160 DSORG=PS with CYL PRI=100 SEC=100 (i.e &SYSUID..DUMPZn).
2. Associate the DDNAME DUMPDD to the dataset allocated in step 1. (i.e ALLOC FI(DUMPDD) SHR DA('&SYSUID..DUMPZn') ).
3. Issue VERBX DMPWRITE 'n' where n is the nth dump entry listed in VERBX DMPWRITE output.

If more than one captured dump is needed, repeat the above steps changing the value for 'n'.
