Load balancing

Bravura Security Fabric can take advantage of SAP’s load balancing capabilities when verifying or resetting passwords or managing accounts. Your SAP server and client must be configured to support load balancing in order to use this feature.

To configure Bravura Security Fabric to use SAP load balancing:

  1. Add an SAP target system to Bravura Security Fabric .

  2. Replace the hostname argument in the target system address for the Server option with the SAP message server name, and optionally, the system ID and group name (separated by a |).

    <message server>[|<system ID>|<group name>]

    The load balancing parameters are as follows:

    • message server The server name or IP address of the message server. When a user logs on to the SAP system, the message server routes them to the appropriate application server.

    • system ID The name of the SAP target system (for example, PRD).

    • group name The application server group name to be used.

  3. Set the systemNo to -1.

For example, to target an SAP system using load balancing, type:

 mesgsrv.example.com|PRD|HR/system=-1/client=000/version=4.6c

If you receive a message like the following from agtsap/agtsapnw :

  LOCATION CPIC (TCP/IP) on local host
  ERROR service 'sapmsDH2' unknown

edit the C:\%windir%\system32\drivers\etc\services file on the Bravura Security Fabric server on which the SAP client is installed. Include entries mapping the R/3 system name and number of each SAP server; for example:

 sapmsDX1 3636/tcp
 sapmsDR2 3610/tcp
 sapmsDW2 3615/tcp
 sapmsDC2 3612/tcp
 sapmsDE2 3614/tcp
 sapmsDB2 3613/tcp
 sapmsDH2 3616/tcp
       ^    ^^

Where the character indicated by ^ is related to the R/3 system name in the target system address line, and the numbers indicated by ^^ are related to the system number. Obtain these values from an SAP administrator.
