This section lists common questions and answers related to the Pax-Enhanced ESD process.
#1: What is the Pax-Enhanced ESD process?
The enhanced process lets you download software directly to your mainframe and eliminates the need to download files to tape. We implemented the Pax-Enhanced ESD process in response to customer requests.
#2: How is the process different? What has changed?
When using the traditional ESD process, you upload the ESD file to the mainframe and create a product installation tape using a utility program provided by CA.
The Pax-Enhanced ESD process eliminates the need for a tape and uses superior compression technology that reduces file transfer times. This process uses a UNIX portable archive interchange (pax) file. Standard z/OS utilities can read and expand the file directly to your mainframe system.
#3: Why did CA choose to use and require customers to use UNIX System Services (USS)?
To improve the CA product installation process for our customers. The following list details some of the benefits of using the USS pax format to distribute software packages:
#4: Do I need to do anything differently as a result? Are there any new requirements or any dependencies? Am I required to have an in-depth knowledge of UNIX System Services (USS) to use the Pax-Enhanced ESD process?
A basic understanding of USS is sufficient if you understand UNIX and follow the steps in this guide. The appendix in this guide lists and defines common USS commands. In addition, the appendix lists IBM documents that provide detailed information about USS.
#5: What can I expect when I transition to the Pax-Enhanced ESD process?
You may experience a slight learning curve the first time you use the enhanced process. We recommend reading this guide in its entirety before using the Pax-Enhanced ESD process.
#6: Why did CA implement the new process?
We received customer requests to eliminate the need to create an intermediate tape during the software installation process. Pax-Enhanced ESD supports installation completely from files on DASD, allowing customers to obtain and benefit from the latest CA product software releases and updates quickly, and with less manual effort.
In addition, Pax-Enhanced ESD is one of the first deliverables based on our Mainframe 2.0 strategy, which is designed to simplify software installation and other system administration functions on z/OS. We invite you to visit http://www.ca.com/mainframe2 to learn more about Mainframe 2.0.
#7: Does CA still provide products and maintenance on cartridge tapes?
Yes. You can still order cartridge tapes. However, we strongly recommend using the Pax-Enhanced ESD process because it is faster and more secure than the physical tape delivery method.
#8: Are there software prerequisites for the Pax-Enhanced ESD process?
Yes. The Pax-Enhanced ESD process requires SMP/E 3.4 with IBM APAR IO07810 (or higher). You can get the latest release of SMP/E from IBM at no charge.
#9: What version of Java do I need?
The Pax-Enhanced ESD process does not require Java. If the Integrated Cryptographic Services Facility (ICFS) is not active, the GIMUNZIP SMP/E utility requires Java 1.4 or higher to generate an SHA-1 hash value.
#10: Does this process require a specific version of z/OS?
No. You can use Pax Enhanced-ESD on any supported version of z/OS.
#11: How do I know that the files I'm working with are the most current?
