IZDPDISC procedure

The IZDPDISC procedure includes a step to run the z/OS® DLA and another optional step to FTP transfer the output XML files to the Discovery Library File Store.

This procedure is invoked by sample IZDJRUN. It can also be invoked by an operator command or automation product by issuing the S IZDPDISC command.

The following parameters are included for the IZDPDISC procedure:
IDMLDSN
The PDSE (partitioned data set extended) for XML output. This data set is allocated if it does not exist. Although not required, use a different PDSE for each z/OS system that runs the z/OS DLA. The default value supplied in the sample is &SYSUID.IZD.V3R2M0.IDML.
PARMMEM
The z/OS DLA configuration file. The z/OS DLA includes several sample

configuration files for convenience. See Appendix D. Samples provided in hlq.SIZDSAMP. The default IZDCDEF causes the DLA to discover z/OS, zSeries hardware, virtualization (Sysplex and z/VM® guest), and active subsystems (such as Db2®, IMS and CICS® regions), lower-level, potentially high-volume detail, is by default filtered out. For example, Databases, Transactions and Programs are by default filtered out. Alternatively, a configuration file may be specified in stream within batch jobs by using //IZDPARMS DD *. The default value included in the sample is IZDCDEF.

IZDHLQ
The high-level qualifier of the z/OS DLA target data sets. The default value included in the sample is IZD.V3R2M0.
FTP
Set to either Y or N. The z/OS DLA generates FTP statements to transfer the output XML files to the Discovery Library File Storage. If FTP=Y, the FTP step in the IZDPDISC procedure is invoked to perform the transfer. The default value included in the sample is Y.
FTPMEM
The FTP initial statement file. This parameter is applicable only if FTP=Y is specified. The initial FTP statement file contains the FTP statements that are required to connect to the remote system that contains the Discovery Library File Store. The default value included in the sample is IZDCFTPI.
Note that the default IDMLDSN parameter contains system symbol &SYSNAME. When this procedure is invoked as a started class, this symbol resolves to the SYSNAME of the LPAR that DLA is running on. System symbols are not resolved in batch jobs. (See the z/OS MVS JCL Reference.)

When discovery completes, the started task also completes. That is, this started task is a transient started task. For detailed information on the statements in the IZDPDISC procedure, see the sample in SIZDSAMP.
