Installation Prerequisites

This section describes the prerequisites for Adabas System Coordinator Version 8.3.

Operating Systems

Adabas System Coordinator is compatible with the following operating system environments:

  • z/OS

  • z/VSE

  • BS2000

Note:
For information regarding Software AG product compatibility with IBM platforms and any IBM requirements for Software AG products, please review the Product Compatibility for IBM Platforms for IBM Platforms web page.

Note:
Adabas System Coordinator currently executes in 31-bit addressing mode only.

Adabas

Adabas System Coordinator can be used with

  • any supported level of Adabas, or

  • any supported level of Adabas Cluster Services, or

  • any supported level of Adabas Parallel Services.

The following table describes the Adabas version specific maintenance required for supporting Adabas System Coordinator version 8.3 SP1:

Adabas Version Maintenance
ADA83n (incl. AZP835) COR831.LX01 (see note below)
ADA841 AI841009
ADA842 AI842004
AZP843 and above None required

Note:
The supplied COR831.LXnn library is only required for Adabas nuclei running Adabas 8.3.

This LX library contains compatible versions of the Adabas System Coordinator database components and must be concatenated above any Adabas 8.3 library.

For BS2000 installations, the COR831.LXnn library must be named in the ADD-FILE-LINK statements for the DDLIB and the BLSLIB00 file links.

For Adabas nuclei running Adabas 8.4 or later, it is no longer necessary for a CORvrs.LXnn library to be concatenated above the Adabas library for Adabas nuclei.

Adabas Nucleus Memory Requirements

The use of any Adabas System Coordinator Add-on products will require memory in the affected Adabas nucleus jobs.

The minimum memory requirements can be approximated by first considering the Add-on product mix using the table below:

  COR AAF AFP ATM AVI
Memory requirement +1 MB +0.25 MB +1 MB +1 MB +1 MB

In addition to this a further 15k is required for each defined Adabas thread (ADARUN NT=).

Example

The approximate memory requirement for an Adabas nucleus with ADARUN NT=85 running Adabas Fastpath is calculated as follows:

1 MB (for COR) + 1 MB (for AFP) + (15k * 85) = 3.25 MB

Memory requirements will be greater if any of the AFPLOOK and AVILOOK database reporting tools are activated.

For AFPLOOK:

If activated using the following defaults:

  • Maximum Files = 64

  • Command/Descriptors per File = 32

  • Maximum Concurrent Users = 100

  • Maximum CIDs per User = 10

Then the additional nucleus memory required is approximately 100k.

If the Command/Descriptors per File and Maximum CIDs per User are kept at 32 and 10 respectively:

  • Each additional file above 64 files will require 1k

  • Each additional user above 100 users will require 288 bytes

For AVILOOK:

If activated AVILOOK will require an additional 200k of nucleus memory.

Natural

Natural is required by the Online Services application SYSCOR.

Any supported level of Natural can be used. Refer to the Natural documentation for more information.

If the Adabas System Coordinator client component CORS09 is in use at your site then refer to Multi-Task Server Environments using CORS09 for additional prerequisite information.

Com-plete

Any supported level of Com-plete can be used. Refer to the Com-plete documentation for more information.

Adabas System Coordinator-based Add-on products

You can use the following Adabas System Coordinator based Add-on products in conjunction with Adabas System Coordinator version 8.3:

  • Adabas SAF Security (AAF) 8.2 SP2

  • Adabas Fastpath (AFP) 8.2 SP2

  • Adabas Transaction Manager (ATM) 8.2 SP2

  • Adabas Vista (AVI) 8.2 SP2

The following table describes the Add-on product maintenance required for supporting Adabas System Coordinator version 8.3:

Add-on Product Fix number
Adabas Fastpath AFP822I005, AW822056, AW822057
Adabas SAF Security AAF822I002
Adabas Transaction Manager ATM822I003, AT822035
Adabas Vista AVI822I006

Note:
For information regarding the necessary Adabas System Coordinator-based Add-on maintenance required for the version of Adabas you are running, refer to the section Using COR-based Add-ons in the release notes for the appropriate Adabas version.

Multi-Task Server Environments using CORS09

The Adabas System Coordinator client component CORS09 was made widely available in Version 8.2.2 Patch level 3 as a replacement for CORS07 for those customers who run zIIP enabler for Natural in multi-task server environments.

For Adabas System Coordinator 8.3 SP1 and above, Natural zap NA97065 is a prerequisite for the continued use of CORS09 in conjunction with zIIP enabler for Natural. The absence of NA97065 may result in a RSP101 Subcode 22.
