Date Description
March 10, 2014 Update available for z/VSE's PAV (Parallel Access Volume) support:
APARs DY47396 (for z/VSE 4.3) and DY47501 (for z/VSE 5.1) address and correct several problems in z/VSE's support for PAV (Parallel Access Volume) devices. If you are using or plan to use PAV devices with z/VSE it is strongly recommended to apply these APARs.
July 5, 2013 Improved Stand-Alone Dump Program
APAR DY47471 addresses several problems in the Stand-Alone dump program. After installing PTF UD53951 a rebuild of the Stand Alone Dump program on disk and/or tape is required.
In IUI select
   	4  Problem Handling    
then 	6  Dump Program Utilities   
then	1  Create Standalone Dump Program on Tape  
or	2  Create Standalone Dump Program on Disk
to create a job which will rebuild the Stand-Alone dump program and for disk reformat the IJSYSDU dump file.
July 15, 2009 Updated list of PTFs for ACF/VTAM V4.2 31-bit I/O Buffer support
In 2006 IBM introduced the ACF/VTAM V4.2 31-bit I/O Buffer support. This support needs additional PTFs for its full functionality. For a complete list of PTFs for z/VSE 3.1 or z/VSE 4.1 or z/VSE 4.2 see here.
May 28, 2009 Support for PAV is now available
Parallel Access Volume (PAV) is an optional licensed feature of the IBM System Storage DS8000 and DS6000, and IBM TotalStorage ESS series. It enables a single System z server to simultaneously process multiple I/O operations to the same volume.

PAV support is now available in z/VSE V4.2 with APAR DY46953/PTF UD53399 (01C) and UD53400 (01J).

Note: When running under z/VM and using z/VM's PAV minidisk support the ALIAS minidisks must be defined in the CP Directory for the guest (MINIOPT PAVALIAS). Using the CP command DEFINE PAVALIAS to dynamically define an alias might lead to z/VSE system hangs.
June 18, 2007 The IBM System Storage TS1120 Tape Drive encryption feature support is now available for z/VSE V4.1 and V3.1.
Following APARs/PTFs must be installed to activate the support:
For a detailed description please see the updated chapter Implementing Hardware-Based Tape Encryption (PDF, 231KB) in the z/VSE V4R1 Administration guide.
April 13, 2007 Error in z/VSE 4.1 when trying to load DLA on disk
When using an old $0JCL from a previous release with // EXEC PROC=STDLABEL before // VDISK for DLA has been defined, the system should issue message 1L41D but instead the following error messages may be issued:
          RET.CODE=0E REASON CODE=06
          RET.CODE=0E REASON CODE=04
Circumvention: remove the // EXEC PROC=STDLABEL as described in chapter 5 of z/VSE V4R1.0 System Upgrade and Service.
// EXEC PROC= STDLABEL (remove this statement)
July 28, 2006 Installing Generation Feature may remove UD52824:
During installation of the VSE generation feature under releases z/VSE 3.1.1 or z/VSE 3.1.2, the PTF UD52824 is accidentally being removed from the MSHP history file, but the corrected code by UD52824 remains applied and intact. However, any subsequent installation by PTF UD52908 or any other PTF with a PRE REQ requirement of UD52824 will fail. Therefore, this archive job will provide the resolution to the above stated MSHP problem.
July 21, 2006 z/VSE V3.1.2:
z/VSE V3.1.2 is now available. It contains hardware support and functional enhancements first introduced in z/VSE V3.1.1. z/VSE V3.1.2 contains accumulated service since the z/VSE V3.1 GA in March 2005.

Note: Special instructions have been provided that describe detailed procedures for a) an FSU, or b) a new install of z/VSE V3.1.2. It is essential that users follow correct procedures to make the process as smooth as possible and to avoid any possible loss of existing definitions.
February 13, 2006 New ACF/VTAM V4.2 31-bit I/O Buffer support for z/VSE V3.1:
In the current ACF/VTAM implementation, VTAM I/O buffers use 24-Bit System Getvis storage. For some customers, this restriction creates a storage constraint. Customer requiremens (e.g. WAVV200414, WAVV200311, WAVV200242, WAVV200224) have requested that IBM allows to move these I/O buffers 'above the line' (into 31-Bit System Getvis storage).

IBM's response is the VTAM 31-Bit I/O Buffer Support in z/VSE 3.1. With this new function, ACF/VTAM can move I/O buffers (IOBUF pool) and all I/O CTC packing buffers in 31-Bit System Getvis storage (VTAM startup option IOBUF31=YES). This enhancement allows z/VSE customers to grow their communication workloads.

To use this support PTF UD52873 and PTF UD53035 (AF Base) or UD52874 and UD53060(Generation Feature) must be applied to z/VSE V3.1. In addition PTF UD52964 and PTF UD53054 must be applied to ACF/VTAM V4.2.
February 9, 2006 With z/VSE 3.1.1, initial installation may fail, first IPL goes into a loop:
A few users experienced problems with the initial installation of z/VSE V3.1.1. For technical details and a local fix see here (PDF, 8KB). As a result, we developed a solution (APAR DY46515). We applied the APAR and replaced the z/VSE V3.1.1 tapes at the distribution centers as of February 8.

z/VSE V3 customers fall into three groups:
In summary, the z/VSE V3.1,1 system you order now includes an important fix. We recommend that all customers with z/VSE V3.1.1 'on the shelf' (but who have not yet installed it for whatever reason), reorder z/VSE V3.1.1 before trying to install the system.
