Learn how to intialize Zowe custom MVS data sets by using the
zwe init mvs command.
During the installation of Zowe, three data sets
SZWEEXEC are created and populated with members copied across from the Zowe installation files. The contents of these data sets represent the original files that were provided as part of the Zowe installation and are not meant to be modified because they will be replaced during subsequent upgrades of Zowe version 2.
For modification and execution, you must create custom data sets by using the
zwe init mvs command. For detailed information about this command, see the
zwe init mvs command reference.
zowe.yaml section that contains the parameters for the data set names is:
zowe: setup: dataset: prefix: IBMUSER.ZWE parmlib: IBMUSER.ZWE.CUST.PARMLIB jcllib: IBMUSER.ZWE.CUST.JCLLIB authLoadlib: IBMUSER.ZWE.CUST.ZWESALL authPluginLib: IBMUSER.ZWE.CUST.ZWESAPL
The storage requirements for the three data sets are included here.
|Library DDNAME||Member Type||zowe.yaml||Target Volume||Type||Org||RECFM||LRECL||No. of 3390 Trks||No. of DIR Blks|
|CUST.PARMLIB||PARM Library Members||zowe.setup.dataset.parmlib||ANY||U||PDSE||FB||80||15||5|
|CUST.ZWESAPL||CLIST copy utilities||zowe.setup.dataset.authPluginLib||ANY||U||PDSE||U||0||15||N/A|
To initialize Zowe custom data sets, run the following command:
zwe init mvs -c /path/to/zowe.yaml
Here is an example of running
zwe init mvs.
#>zwe init mvs -c ./zowe.yaml------------------------------------------------------------------------------->> Initialize Zowe custom data sets Create data sets if they are not existCreating IBMUSER.ZWEV2.CUST.PARMLIBCreating IBMUSER.ZWEV2.CUST.JCLLIBCreating IBMUSER.ZWEV2.SZWEAUTHCreating IBMUSER.ZWEV2.CUST.ZWESAPL Copy IBMUSER.ZWEV2.SZWESAMP(ZWESIP00) to USER.ZWEV2.CUST.PARMLIB(ZWESIP00)Copy components/zss/LOADLIB/ZWESIS01 to USER.ZWEV2.SZWEAUTH(ZWESIS01)Copy components/zss/LOADLIB/ZWESAUX to USER.ZWEV2.SZWEAUTH(ZWESAUX)Copy components/launcher/bin/zowe_launcher to USER.ZWEV2.SZWEAUTH(ZWELNCH) >> Zowe custom data sets are initialized successfully.#>
If this step is successful, there will be three custom data sets matching the values in
zowe.setup.dataset.authPluginLib in the
zowe.yaml file. The member
ZWESIP00 will exist in the
CUST.PARMLIB and the
ZWESAPL will be empty.
In addition to the three custom data sets, the PDS
SZWEAUTH is created. This may already exist. In this case, you will receive the error message
Error ZWEL0158E: IBMUSER.ZWEV2.SZWEAUTH already exists. You can ignore this message, or you can use the
--allow-overwritten option on the command. For example,
zwe init mvs -c zowe.yaml --allow-overwritten.
