These new and enhanced capabilities are available in z/OS® Explorer Version 3.1.1.x.

Table 1. New and enhanced functions from V3.1.1.29 to V3.1.1.32
Function Description
Execute JES Job Monitor as user job You can now execute JES Job Monitor as a user job. When JES Job Monitor is not active as a started task, it will query your security product for explicit permission to start. For more information, see JMON, JES Job Monitor started task.
Security in starting up RSE daemon as a user job You can now execute RSE daemon as a user job securely. When RSE daemon is not active as a started task, it will query your security product for explicit permission to start. For more information, see RSED, RSE daemon started task.
Update to JES Security When JES Job Monitor queries for permission to the related profile in the JESSPOOL class, you can make JES Job Monitor assure access is granted when the JESSPOOL class is not active. For more information, see Access to spool files.

Updates to ICSF When you use JCECCARACFKS, ICSF does permission checks at thread level instead of process level for JCERACFKS, which implies that each user ID that connects must have access to the private key of the server certificate. For more information, see (Optional) ssl.properties, the RSE encrypted communication.
A new definition GSK_SERVER_TLS_KEY_SHARES is added to rse.env. You can use this definition to specify the encryption key share groups in order of preference as a string consisting of one or more 4-character values. For more information, see rse.env, the RSE configuration file.
