Introduction

Scope

The following rules apply to both Solution Manager 7.0 EhP1 and 7.1, unless they are

tagged [7.0 EhP1 only] or [7.1 only]

Terminology

The term host in this slide set does not designate network alias. Hosts must have their own IP addresses.

A Virtual host designates a simulated host running for example on top of a VMware.

A Logical host designates a network/host configuration which associates a physical host with one or more additional host names and dedicated IP addresses. This is

used, for example, to move systems from one physical host to another.

N.B.: To find the host name of an ABAP system, use transaction sm51, and for Java

systems refer to the System Info Web page.


What is needed and where? (Diagnostics Agent or Agents On-the-fly)

New feature available

Solution Manager 7.1 SP05 provides a new feature named Agents On-the-fly

Agents On-the-fly concept introduces automatic Agent instantiations to address specifically the following use cases:

Managed systems in High Availability environments

Physical or Virtual hosts running a high number of Logical hosts (outside High Availability environments)

Further details on Agents On-the-fly available in online documentation : Click here

Existing installations

Previous Diagnostics Agent installation process is still valid.

Operate either classic Diagnostics Agents or Agents On-the-fly, depending on each Managed system environment.

Diagnostics Agent installations already in place are still valid and do not necessarily need to be replaced by the Agent On-the-fly feature. Nevertheless in High Availability environments it

could be of interest to put Agent On-the-fly in place.


What is needed and where? (Diagnostics Agents)

Rule #1:

Install the required number of Diagnostics Agents

In the context of each Solution Manager System use only one Diagnostics Agent or Agent On-the-fly per Managed host. Managed hosts are primarily logical hosts, or if not applicable

physical/virtual hosts (as shown on the next slides)

Each Diagnostics Agent or Agent On-the-fly manages, on behalf of one Solution Manager, the systems/components running on the host on which it is running (and represents that host)

following slides explain what is a supported systems/components

repeat the Managed System configuration (solman_setup) on each Solution Manager for each Technical System running on these hosts (logical host, or if not applicable physical/virtual host).

Activities Byte Code Adapter Installation and Introscope Host Adapter have to be performed only in one leading Solution Manager system (see page 10)

For landscapes with logical host names and in case Agents On-the-fly are not used, specify, during the Diagnostics Agent installation, each time the logical host name

When installing an (additional) Agent for a logical host, using the Diagnostics Agent installation

package, provide the short hostname, in the SAPInst step requesting a Virtual host name.

Rule #1 (continued):

How to use Agents On-the-fly (available with Solution Manager 7.1 SP05)

Mandatory context:

Managed systems in High Availability environments

Physical or Virtual hosts running a high number of Logical hosts (outside High Availability environments)

Use case:





Preparation

Diagnostics Agent landscape preparation:

Remove existing Diagnostics Agents at Physical, Virtual and Logical host level (in concerned landscape)

Pay attention to recommendations for Diagnostics Agents Removal, to avoid potential Java Managed

System startup failures (see page 29)

Install Diagnostics Agents only at Physical or Virtual host level, without specifying any Logical hostname, using the Diagnostics Agent standalone installation package 7.30 SP02 (SAPInst )





Configuration

Diagnostics Agent Configuration:

Start the Host configuration for each Physical or Virtual host

Available under solman_setup / Managed System Configuration / Hosts

Especially enable the Agents On-the-fly feature within step Enter System Parameters

Adjust exclusion filters to have only relevant logical hosts, before saving press button.

Logical host filtering-impact simulation is available via Display resulting host list button. Defining appropriate filters will avoid having irrelevant Agents On-the-fly instantiated.

Agents On-the-fly get instantiated by the Diagnostics Agent running on the Physical or Virtual Host,

as soon as the Enter System Parameters step is saved.

Using Agents On-the-fly:

Simply run as usual solman_setup / Managed System Configuration for implied Managed Systems

In case no Agent On-the-fly for the Managed System logical hosts is visible within the step Assign Diagnostics Agents (similar to Diagnostics Agents), double check above pre-requisite items.

What is needed and where? (SAP Host Agent)

Rule #2:

Have up-to-date SAP Host Agents

See SAP note 1365123 for the current minimum version

This note also confirms whether the installation/upgrade of the SAP Host Agent, performed by the installation of a Diagnostics Agent (installer 7.30 SPxx) covers currently known defects.

Install a SAP Host Agent if none has yet been installed (one per physical host)

Check whether there is a SAP Host Agent using the following path:

o For Windows look under: "%ProgramFiles%"\SAP\hostctrl

o For Unix, under: /usr/sap/hostctrl/

Update the SAP Host Agent according to SAP note 1031096, if the version is not sufficient

Check version at OS level (looking in the output at SAPHOSTAGENT Information):

o For Windows: "%ProgramFiles%"\SAP\hostctrl\exe\saphostctrl -function ExecuteOperation -name versioninfo

o For Unix: /usr/sap/hostctrl/exe/saphostctrl -function ExecuteOperation -name versioninfo

[7.1 only] Currently installed Host Agent version is also visible in the host browsing, if Managed System Configuration has been performed with solman_setup

o Navigate to Solution Manager Administration work center -> Select Landscape + Technical System

selection type -> System Details -> System Details -> Hosts -> -> Host Status


What is needed and where? (SAP Host Agent)


Have up-to-date SAP Host Agents

Implement automatic upgrade process (especially if you plan an update)

SAP note 1473974 describes ways to upgrade centrally and automatically, running SAP Host Agents.



Rule #3:

The Diagnostics Agent is a standard SAP system

The same rules apply as for any standard SAP system

Do not install an Agent in the directory structure of another SAP system (or copy or move the files)

Agents must be independent of any other system installation

Several Diagnostics Agents can be installed using the same SID, but different instance numbers, in case they use the same kernel.

The agent SID must contain only Diagnostics Agent instances

Diagnostics Agents typically have different System/Instance ID patterns, depending on the

release (see following slides)



Rule #3 (details):

Alternatives for installing multiple Diagnostics Agents on the same host

These Agents have to be connected to different Solution Manager systems

Use the same dedicated System ID (and different instance numbers)

Exception: Do not use a same SID for Diagnostics Agents with different kernel releases (this is prevented by the latest installers).

Using different System IDs (and different instance numbers)

Allows independent installations, but requires internal distinct SID allocation rules in case the file system is mounted. It is indeed strictly forbidden to share the same Agent binaries/configuration files

for multiple Agent instances. In particular, a same Diagnostics Agent file system installation must NOT

be mounted and executed on several hosts at the same time.

installing a Diagnostics Agent to comply with rule #3.

A summary of Diagnostics Agents releases and characteristics is on the next slide

With Solution Manager release lower than 7.0 EhP1 SP20 only use older Diagnostics Agent release 7.01 SR1.

This Diagnostics Agent release is installable with the help of the SAP EhP1 for SAP

NetWeaver 7.0 Installation Master, Kernel & Java DVDs. A separately installed JDK 1.4.2 is

also required.

Available Diagnostics Agent connectivity options per installation scenario:

1. Diagnostics Agent is already installed silently with a managed system

The agent is registered in the System Landscape Directory specified during the managed system installation

o The agent could be connected to Solution Manager using, for example, solman_setup -> Managed

System Configuration. This will configure the agent remotely, to connect to Solution Manager via the

Message Server.

No System Landscape Directory is specified during the managed system installation

o Connect the agent to Solution Manager via the Message Server using the smdsetup script, as

documented in the Diagnostics Agent troubleshooting guide (http://service.sap.com/diagnostics ->

Media Library).



2. Agent is installed using a Diagnostics Agent standalone installation package

During the agent installation, choose to connect it to Solution Manager (via the Message Server) instead of only registering it in a System Landscape Directory. This will reduce the number of activities

to be performed in solman_setup.

Solution Manager connectivity data can be re-pushed to running Diagnostics Agents (useful in case of operational issues), in case the agent was also registered in a central System Landscape Directory.

NEW: Operational issues concerning Diagnostics Agents to Solution Manager connectivity can be

easily resolved via the Non-authenticated Agents list, available with Solution Manager 7.1 SP05.

Prerequisite: Diagnostics Agent was connected to a Solution Manager 7.1 SP05 system at least once.


Diagnostics Agent Mass Installation

Use the SAPInst unattended mode to install Diagnostics Agents rapidly over a

wide consistent landscape

Unattended mode allows the Diagnostics Agent standalone installation package to install a number of agents in silent mode

Installation template available for Diagnostics Agents 7.30 in SAP note 1486330


Diagnostics Agent Upgrade

Rule #5:

No need to upgrade Diagnostics Agents (in contrast to SAP Host Agent)

Diagnostics Agents take their business logic (software) from the Solution Manager system

to which they are connected

All Diagnostics Agents running and connected in the landscape are centrally patched by applying an LM-

SERVICE Java Software Component Archive on the Solution Manager system

Diagnostics Agent Installation SAP notes include a guide and simple manual procedures needed to resolve known punctual issues (support of cryptography, ). Alternatively, use the later described Agent replacement procedure.

Some OS platform constraints might require a Diagnostics Agent Kernel upgrade. See SAP note 1707141.




To replace a Diagnostics Agent uninstall the previous Agent and install the

new required release:

Reset server name

Login to the Solution Manager system to which the agent to be upgraded is connected

Navigate to the Agent Administration and note the server name of the old agent

Reset server name using the context menu of the agent, and stop the agent

Install new Diagnostics Agent release using a different SID (no upgrade tool available)

Assign the same Server Name to the new Agent using the smdsetup script (see details in the Diagnostics Agent troubleshooting guide).

Java based Managed systems require to take some specific actions (see next slide)

Uninstall the previous Diagnostics Agent using SAPInst



Rule #5 (In context of Java Managed System):

In case the Ensure HA virtualization compatibility option was not used in the past:

Configure again the Wily Introscope Agent (Byte Code Adapter Installation) using transaction solman_setup -> Managed System Configuration -> Configure Automatically

Pre-requisite since Solution Manager 7.1 SP05:

Mark additionally the option "Ensure HA virtualization compatibility" within step "Enter System

Parameters". Also ideally provide only a relative path name like ByteCodeAdapter for the "Introscope

BC Adapter deployment path" field, in order to locate the Byte Code Adapter binaries and configuration

files inside the Managed system directory structure (/usr/sap//).

The Diagnostics Agent OS user (members of the SAPSYS OS group) must therefore also have write

permissions at this Managed System path location. See SAP note 1163751

Restart the Java managed system

This procedure updates the Managed System JVM parameters so that the Introscope Byte Code Adapter

binaries are no longer taken from the previous old Diagnostics Agent directory structure.


Diagnostics Agent Removal

Rule #6:

To remove a Diagnostics Agent instance installed for a specific hostname:

In case the solman_setup Ensure HA virtualization compatibility option was used in the past to setup the Byte Code Adapter of the Java Managed System(s) running on that host

Optionally: Uninstall also the Byte Code Adapter by removing the JVM parameters listed in SAP note

797147

Else, take the following actions (in case the Ensure HA virtualization compatibility option was not used in the past during the solman_setup Managed System Configurations):

IMPORTANT: Remove JVM parameters listed in SAP note 797147 on the Java Managed System

used to start/run the Introscope Byte Code Adapter.

Finally restart the Java Managed system to no longer run the Introscope Byte Code Agent

The Managed System JVM parameters (to be removed) show that the Introscope Byte Code Adapter executed inside the Managed System uses files from Diagnostics Agent directory structure:
