Prerequisites for IBM Z

Edit online

Before you install Copy Services Manager on z/OS® systems, ensure that the hardware and software requirements are met.

Hardware requirements

  • Minimum disk space requirement: See the IBM Copy Services Manager for z Systems® Program Directory or the IBM Copy Services Manager Basic Edition for z Systems Program Directory for details.
  • Memory: 768 MB minimum memory allocation to UNIX System Services for Java™™ virtual machine
  • Processors: zIIP or zAAP processors should be used to handle the Copy Services Manager workload and avoid the cost of millions of instructions per second (MIPS). zIIP and zAAP are special processors that are used specifically for products that operate on WebSphere® for z/OS and Java workloads.
  • Server memory requirements: See the topic titled "Calculating server memory requirements" in the online help documentation at https://www.ibm.com/support/knowledgecenter/SSESK4 Calculating server memory requirements for more information.
  • Server memory requirements: See the topic titled Calculating server memory requirements for more information.

  • In addition to the memory requirements, when running CSM on z/OS, ensure that UNIX System Services environment is active and that the BPXPRMxx settings meet or exceed the following minimum values (see Preparing z/OS to run WebSphere Application Server)

    MAXTHREADS: 10000

    MAXTHREADTASKS: 5000

    MAXFILEPROC: 10000

    MAXSOCKETS (AF_INET domain): 12000

    SHRLIBRGNSIZE: 67000000 (134000000 recommended)

Port requirements

Ensure that the ports that are shown in Table 1 are available for use. The ports that are shown are the defaults. You can specify different ports if they are available for use.
Table 1. Server port requirements for IBM Z
Port Default port number
GUI 9559
CLI 9560
Active/Standby 9561

Software requirements

  • Operating system: IBM® z/OS
  • z/OS versions: 1.13, 2.1, or 2.2
  • z/OS versions: 2.1, 2.2, 2.3, 3.1

HyperSwap fixes and updates

To ensure that you have the most-recent z/OS APARs, updates, and program temporary fixes (PTFs) that are required to support HyperSwap®, you can get the most-recent IBM HOLDDATA. When you have the HOLDDATA, you then use the fix category IBM.Function.HyperSwap to select and apply the appropriate PTFs or to identify any PTFs that are missing. For the most-recent information on HOLDDATA, see "Enhanced HOLDDATA for z/OS" at the support portal (http://service.software.ibm.com/holdata/390holddata.html). Use the full two-year file only. After you receive the most-recent HOLDDATA, you can use the SMP/E REPORT MISSINGFIX command to identify missing HyperSwap PTFs.

For more information about the REPORT MISSINGFIX command, see SMP/E for z/OS Commands document at http://www.ibm.com/e-business/linkweb/publications/servlet/pbi.wss?CTY=US&FNC=SRX&PBL=SA22-7771-15.
