Do you want to order z/VSE 6.2 ?
I recommend to upgrade to z/VSE 6.2 as soon as possible to stay in a serviced environment for a long term, because z/VSE 5.2 service ends October 31, 2018 and z/VSE 6.1 service ends June 30, 2019. You can order z/VSE 6.2 via IBM Shopz - here . You need to license all products that you require on z/VSE 6.2, even if they come with the z/VSE 6.2 base or extended base, such as CICS TS for z/VSE 2.2, IBM TCP/IP for z/VSE 2.2 or IBM IPv6/VSE 1.3 - see the z/VSE 6.2 Program Directory for details - here . If you want to order z/VSE... [More]

z/VSE release migration: performance
In each new z/VSE release we provide new functionality. Some enhancements are addressing new hardware, some z/VSE's batch and online software stack. If the enhancements affect the main path of the system, it could be that those have minimal impact on CPU resources. If you run application, that make heavy use of system services such as I/O, you may see up to 5% additional CPU usage in case you migrate to a new release. Often the additional CPU requirements per release are less than 3%. If you can benefit from enhancements of the new release... [More]

Migration to new hardware or a new z/VSE release
We describe some migration hints and tips in the "z/VSE Version/Release and Hardware Upgrade" white paper. It can be downloaded form the z/VSE technical article web page - here . Just from past experience, if there are customer complaints about performance differences on the new environment, in most cases there are no historical data from the old environment. In such a case it is hard, if not impossible to analyze the cause of the problem. Therefore good practice is to gather (performance) data from the old environment before... [More]

z/VSE security: Migrate your DTSECTXN to the BSM control file
In July I had a short blog entry about the migration of the old DTSECTXN, which holds the definitions for transaction security, to the Basic Security Manager (BSM) control file. In between we got more detailed questions about the DTSECTXN and its migration. Therefore my colleague Monika looked into that again and will provide more details in the z/VSE Version (Release) and Hardware Upgrade paper, available here . Thanks, Monika. The update will be uploaded within the next weeks. I will keep you posted, when that update is available.... [More]

Where to find information about tools for z/VSE backups
Today's blog entry is related to the backup of z/VSE data. Just recently we got questions about backup tools. The most important backup tools come with the z/VSE product. Others may be provided by vendors. In this blog entry I will only address z/VSE product tools. Back up policies depend on your requirements and guidelines. I assume you all do regular backups of your data to recover e.g. from data corruption. It is good practice to backup the whole system before hardware or z/VSE upgrades to restore the z/VSE environment just... [More]

z/VSE security: DTSECTXN not supported on z/VSE 6.2
Just a few weeks ago I got feedback from customers, that they still use the CICS transaction security table (DTSECTXN). It's time to migrate this table. End of last year I had a blog entry about the migration of DTSECTXN - here . For details how to migrate the DTSECTXN definitions to the BSM control file, refer to the z/VSE Administration book. Links to the z/VSE books are here . In the upcoming z/VSE 6.2 the DTSECTXN will no longer be considered (will be ignored by z/VSE). Therefore, if you still use DTSECTXN to define access... [More]
