Connection Configuration

Refer to the installation procedures contained inside the Diagnostics Setup Guide.

Connection options

Before starting the installation make sure that you have identified which installation strategy you want to use. This means that you need to choose between the two following scenarios:
  • Direct Solution Manager Registration: In this scenario, the Diagnostics Agent establishes a direct connection to the Solution Manager system. Using this type of connection no SLD attachment is necessary especially since Solution Manager 7.1 SP05. Operational issues concerning Diagnostics Agents to Solution Manager connectivity can now be easily resolved via the “Non-authenticated Agents” list. (See Non Authenticated Diagnostics Agents).
    Prerequisite: Diagnostics Agent was connected to a Solution Manager 7.1 SP05 system at least once.
  • SLD Registration: In this scenario, the Diagnostics Agent registers itself into the production SLD assigned to the managed system on which the Diagnostics Agent will be installed. This scenario should be used especially if Solution Manager is not yet installed.

SLD Registration - Remotely Connect DIagnostics Agents  - Solution Manager 7.1

If you choose the "SLD Registration" strategy, the Diagnostics Agent should be visible using SOLMAN_SETUP transaction -> System preparation -> Step "Connect Agents". You must connect the relevant Diagnostics Agents to the current Solution Manager system in order to later be able to use them.
Agent reconnection may require waiting several minutes. It depends on settings which are set on the SMD Agent side. As soon as it detects that the association has been changed the SLD state is updated and the registration should proceed.

Direct Solution Manager Registration

If you want to perform the "Direct Solution Manager Registration" after the installation of the Diagnostics Agent, you will need to perform the smdsetup script action managingconf.
You can perform the direct connection to the solution manager in two ways, using the J2EE Message Server HTTP port (recommended). For more information about the smdsetup script refer to the Diagnostics Agent setup guide attached to the SAP Note for the most recent installer release (see SAP Note 1833501).
Example:
  • Connection by Message Server:
smdsetup managingconf hostname:"sapms://" port:"" [optional user:"<...>" pwd:"<...>"]
To run these script we will need to following information:
  1. Full qualified solution manager hostname.
  2. J2EE Message Server HTTP Port, like 81.
  3. Diagnostics Agent system user: For more information about these user check the User Administration Guide.
  4. Diagnostics Agent system user password.
Where to find the J2EE Message Server HTTP port.
  • J2EE Message Server HTTP: This port is usually 81XX (where xx is the SCS instance number: /usr/sap//SCS).
Make sure that you address the Solution Manager Java SCS Message Server with the above mentioned port number. URL.  Enter in the following URL: http://:/msgserver/text/logon
This shall display a P4 and/or P4S line, like here:


Having all necessary information, you have to perform the smdsetup script to connect the Diagnostics Agent to the Solution Manager system:
   1. Open a prompt command and navigate to the script folder inside of the agent path: usr/sap//SMDAXX/script
   2. Run the smdsetup script as the following examples:
  • Connection by Message Server:
     - smdsetup managingconf hostname:"sapms://solman.full.qual.host.name" port:"81XX" user:"SMD_ADMIN" pwd:"XXXXXXXX"
  •  Afterwards, the command should finish successfully:
Then check at the “Agent Administration” if the agent is connected to the Solution manager. If the agent does not connect to the Solman system check the SMDSystem log for error. This log file can be found into the log folder at the agent path.
IMPORTANT: Note that SAP recommends to use the connection via the Solution Manager Java SCS Message Server. Trying out a direct connection via the P4 or P4S port, is only relevant in some very specific situations.
