Re: ZFS using zEDC hardware compression
Richard Pinion asked: >Can a ZFS dataset be defined with the DATACLAS zEDC compression >option? Then later added: >We're at z/OS 2.2, hoping to go to 2.4 soon, so zfsadm compress >isn't available. IBM introduced zEDC compression (and encryption) for zFS in z/OS 2.3. When you get upgraded to at least z/OS 2.3, including for all shared zFSes across a Sysplex, your new zFS file systems can default to compression at format time, still with the possibility to override the default. Here's the z/OS 2.4 documentation explaining how to do that via the IOEFSPRM configuration option: https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.ioea700/compress_always.htm If you can default to encrypted as well (format_encryption=on), even better. - - - - - - - - - - Timothy Sipples I.T.

And there are consequences of CI (record, slot) update - it can be less compressed. So, compressed VSAM should have some kind of DAT (Dynamic Address Translation) for CI addresses.

Re: ZFS using zEDC hardware compression
I just RTFM. No VSAM dataset can be compressed using zEDC. Of course VSAM datasets dumped with DFSMSdss may be compressed, because: a) output dataset is PS, which is eligible for zEDC compression. b) dss itself can use zEDC to compress data written to output. Such dataset can be writted on tape or disk. There is no reason to make it zEDC compressible. -- Radoslaw Skorupka Lodz, Poland W dniu 08.01.2021 o 17:20, PINION, RICHARD W. pisze: That's a definitive answer, thanks. -Original Message- From: IBM Mainframe Discussion List On Behalf Of Seymour J Metz Sent: Friday, January 8, 2021 11:08 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: ZFS using zEDC hardware compression [External Email.
