Generic VSAM Cluster data

This reference lists the configuration values that you can update for Generic VSAM Cluster data. Currently, the Data Collector doesn’t support collecting paired VSAM data sets in one VSAM gather at the same time. If the paired data sets exist, you need to define two gathers to collect the log data from both VSAM data sets. Only the VSAM ESDS data set is supported.

Data source
You can define the specific data source that you want to collect in the Add/Edit data resource window. In this case, select VSAM.
Data source type
A value that the subscriber can use to uniquely identify the type and format of the streamed data. The value for VSAM Cluster data is zOS-DATA-SET.
VSAM instance name
The name to specify a VSAM gather instance.
Data set name
The name of the entry-sequenced VSAM cluster that contains the data to be gathered. This name must be in the format x.y.z.
Tip: If you want to delete and redefine a VSAM ESDS data set from which the data is gathered by the Data Collector, after deleting the old data set, wait at least 60 seconds (1 minute) before redefining and writing data to the new data set, so that the Data Collector can collect all the records in the new data set.
RLS Access
A specification of whether the monitored VSAM ESDS data set is accessed through RLS or not. The default value is No, which represents that the data set is not accessed through RLS. If the monitored VSAM data set is accessed through RLS, select Yes so that Z Common Data Provider can monitor the data in the correct way.
Tip: For non-RLS ESDS, if there is an application which has a long open connection to it (for example CICS®), the SHAREOPTIONS must be (4,4) or (4,3) to make sure that Z Common Data Provider can continue collecting data after the data size reaches the CI. Otherwise, the remaining data can only be collected after the application performs a CLOSE command to the VSAM data set due to the read/write integrity identified by DFSMS. For RLS ESDS, there is no such requirement. For more information on SHAREOPTIONS, see https://www.ibm.com/docs/en/zos/2.5.0?topic=sharing-cross-region-share-options.
Topic Name
The topic name for Generic VSAM Cluster data collection. The default value is IBM-CDP-DASHBOARDS-{dataSourceType}, of which, dataSourceType will be parsed to the VSAM data type zOS-DATA-SET.
Output format
The output format of Generic VSAM Cluster data collection. The value can be key-value or csv. The default value is csv.
