Well, a quick google: zos iarst64 and the first or 2nd results points to: https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.ieaa900/iarst64.htm ,OWNER=HOME ,OWNER=PRIMARY ,OWNER=SECONDARY ,OWNER=SYSTEM ,OWNER=BYASID When COMMON=YES and REQUEST=GET are specified, a required parameter that designates the owner of the storage. ,OWNER=HOME This parameter indicates that the home address space is to be the owner. ,OWNER=PRIMARY This parameter indicates that the primary address space is to be the owner. ,OWNER=SECONDARY This parameter indicates that the secondary address space is to be the owner. ,OWNER=SYSTEM This parameter indicates that the system is to be the owner. Use this only when there is no specific address space which can be considered the owner. ,OWNER=BYASID This parameter indicates that the owner is the ASID specified by the OwningASID parameter. So you're getting some storage and using an interface which doesn't assume your current asid/task is to "own" the storage. What does "own" mean? Likely it means how the system is to track the lifetime of the storage and tie that lifetime to some task or address space's lifetime or reading the description at the top of the page: Note: There is diagnostic support for 64 bit cell pools, created by IARST64, So there is some sort of cell pooling going on. So perhaps the OWNER indicates which cell pool IARST64 should use too. The description also says: Cross memory mode: Any PASN, any HASN, any SASN AMODE: 64-bit ASC mode: Primary or access register (AR) So SSAR doesn't seem to be required at all. I may not have used MVS for a while, but I can still read IBM manuals... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
