Prerequisites for Adabas

Adabas SQL Gateway (CONNX for Adabas) requires that:

  • The Adabas database product be installed.

  • The target system be set up to support TCP/IP communications (OE stack).

  • The TCP/IP started task must be running.

  • Read/write FTP access be configured and available on the target system for at least one TSO user ID for installation only.

  • OSS segment must be defined for the user ID in a security system (RACF / ACF2 / Top Secret) or it must be available by default.

CONNX for Adabas is a reentrant application which executes as a started task or a batch job. During installation, the CONNX Adabas server program must be linked with the reentrant version of the Adabas batch/TSO link routine (ADALNKR).  Please see the appropriate Adabas documentation for more information on ADALNKR.

Before submitting the CONNX installation job, please check with your systems programmer or Adabas administrator to ensure that the ADALNKR load module exists in a load library which can be link-edited with the CONNX for Adabas object code.


Verifying TCP/IP Connectivity

 Before you install CONNX on your Adabas server, we recommend that you verify the TCP/IP connectivity to your OS/390 z/OS system. To verify connectivity:

  1. Open a Command Prompt window.

  2. On the taskbar, click Start and then click Run

  3. Type or select:

ping hostname

where hostname is the TCP/IP symbolic address or dotted numeric address.

 A successful ping (connectivity) will generate output in the command window similar to the following:

 Pinging with 32 bytes of data:

Reply from bytes=32 time=10ms TTL=63

Reply from bytes=32 time<10ms TTL=63

Reply from bytes=32 time<10ms TTL=63

Reply from bytes=32 time<10ms TTL=63
