Yeah, I also expect a VVDS should have been cataloged under either MCAT or UCAT. However, there is a VVDS, it cannot be shown when I input 'SYS1.VVDS' under DSLIST, but it can be found if I input 'SYS1.VVDS.Vxxxxxx' (full name) under DSLIST. Even the VVDS can be seen under DSLIST with full name search, I didn't see a "*VSAM*" Cluster entry (only a Data Component entry there). In addition, when I issue a 'LISTC ENT(/) ALL' command against the Data Component of that VVDS, it can't tell me where the VVDS is cataloged. So that's why I suspect the VVDS is not cataloged anywhere.....
