Connect Client systems to the “Solution Manager”: Easier, faster and better – Via Outside Discovery with saphostctrl

Introduction

Why should I configure the hostagent, secure and with Outside Discovery enabled?

Because it is easy and It only takes a little to connect correctly the satellite systems to the LMDB with all data suppliers.

And least but not last: to get better Landscape Data in your LMDB to make better Upgrades! (see further Information, at the bottom)

What do I have to do?

On SAP Host Agent folder /usr/sap/hostctrl/exe/ (UNIX) or C:\Program Files\SAP\hostctrl\exe\ (Windows), create some shell scripts or textfiles and run this commands:

1. Make hostagent secure

As root:

export password=secure
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/sap/hostctrl/exe/
export SECUDIR=/usr/sap/hostctrl/exe/sec

if [ ! -d “$SECUDIR” ]; then
mkdir /usr/sap/hostctrl/exe/sec
cd /usr/sap/hostctrl/exe/sec
/usr/sap/hostctrl/exe/sapgenpse get_pse -p SAPSSLS.pse -noreq -x $password CN=`hostname`
/usr/sap/hostctrl/exe/sapgenpse seclogin -p SAPSSLS.pse -x $password -O sapadm
chmod 640 /usr/sap/hostctrl/exe/sec/SAPSSLS.pse
fi

This will enable Port 1129 for hostagent

2. Configure Outside Discovery for hostagent

As root:

export fqhn=`hostname -f`
export port=50000
export user=SL_user_DS
export password=secure

/usr/sap/hostctrl/exe/saphostctrl -function ConfigureOutsideDiscovery -enable -sldhost $fqhn -sldport $port -sldusername $user -sldpassword $password

3. Connect to the SLD (Create “slddest.cfg” and “slddest.cfg.key Files)

As root:
/usr/sap/hostctrl/exe/sldreg -configure /usr/sap/hostctrl/exe/slddest.cfg -usekeyfile

older existing files will be renamed as backup

4. Sent Data to SLD

as root:

export sidadm=sitadm
export SID=SIT
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/sap/hostctrl/exe/

# for the hostagent
/usr/sap/hostctrl/exe/saposcol -b | /usr/sap/hostctrl/exe/sldreg -connectfile /usr/sap/hostctrl/exe/slddest.cfg -stdin -ol dtransferdtd

# for the <SID> (ABAP)
DIR=/sapmnt/$SID/global
if [ -d “$DIR” ]; then
cp /usr/sap/hostctrl/exe/slddest.cfg $DIR
cp /usr/sap/hostctrl/exe/slddest.cfg.key $DIR
fi
su – $sidadm -c “setenv LD_LIBRARY_PATH /usr/sap/hostctrl/exe; /usr/sap/hostctrl/exe/saposcol -b | /usr/sap/hostctrl/exe/sldreg -connectfile /usr/sap/hostctrl/exe/slddest.cfg -stdin -ol dtransferdtd”

# for the <SID> (HANA)
DIR=/hana/shared/$SID/global
if [ -d “$DIR” ]; then
cp /usr/sap/hostctrl/exe/slddest.cfg $DIR
cp /usr/sap/hostctrl/exe/slddest.cfg.key $DIR
fi
su – $sidadm -c “setenv LD_LIBRARY_PATH /usr/sap/hostctrl/exe; /usr/sap/hostctrl/exe/saposcol -b | /usr/sap/hostctrl/exe/sldreg -connectfile /usr/sap/hostctrl/exe/slddest.cfg -stdin -ol dtransferdtd”

 

5. Register Hana DB into the SLD

Create config.txt File

[General]

# SLD Host Name
sld_hostname=<hostname.domain>

# SLD Port
sld_port=<Port-Nr.>

# Remote Execution ( Default: ssh; Valid values: ssh | saphostagent )
remote_execution=ssh

# SLD User Name
sld_username=<USER>

# SLD Password
sld_password=<Password>

# Use HTTPS
https=n

[Action]

action=configure_sld

 

now execute

As root:

export SID=SIT

/hana/shared/$SID/hdblcm/hdblcm –configfile=/tmp/hostagent/config.txt

Bonus

Register SystemDB to saphostctrl Agent

as root:

export passwort=secret

SYSTEMDB

/usr/sap/hostctrl/exe/saphostctrl -host name -user sidadm $passwort -dbname SYSTEMDB@SID  -dbtype hdb -dbuser SYSTEM -dbpass $passwort -function SetDatabaseProperty DBCredentials=SET -dboption User=SAPDBCTRL -dboption Password=$passwort

TENANT

/usr/sap/hostctrl/exe/saphostctrl -host name -user sidadm $passwort -dbname TENANT@SID  -dbtype hdb -dbuser SYSTEM -dbpass $passwort -function SetDatabaseProperty DBCredentials=SET -dboption User=SAPDBCTRL -dboption Password=$passwort

That’s all, see the result:

Technical System Application Server ABAP

Technical System SAP Hana Database

Hosts

that’s what I want !!!

 

Logfiles to check

under /usr/sap/hostctrl/work/

dev_saphostexec

outsidediscovery.log

dev_sapdbctrl

under /usr/sap/hostctrl/exe

sldreg.log

 

Conclusion

spend a little time at the beginning will save a lot of time at the end.

      Hello Christoph,

      thank you for the great overview.

      Just one remark: I am not totally agree with the headline "connect satellite systems".

      The outside discovery is just a part for hosts - technical systems (ABAP and Java) are synchronized with specific data suppliers: RZ70; NWA (>AS Java 7.02) or Visual Admin (</= AS Java 7.02) directly to a LMDB (since Solman 7.2 SPS 06; see Note 2836143) or via the synchronization from a SLD instance.

      Your blog describes one necessary prerequisite (next to the SMD Agent rollout and assignment; setup EFWK; creation of scenarios...) for capabilities in the area of the Application Operations. If a customer is just looking for using ChaRM; ITSM; Process Management; Test Suite; Basis Operations like Maintenance Planner or SLM ... the outside discovery is not a functional requirement since we are using technical instances or iObjects in the iBase to manage satellite systems.

      Kind regards Tim

      Hi Tim,
      Your right, so I changed to "Client" ! My Intension is to connect easy Systems direct to sld and have all nessesary Data supplier for Kernel, Host, Database in one go
      my inspiration was also: https://launchpad.support.sap.com/#/notes/2556432
      thank you for your feedback
      kind regards
      Christoph

      Hello Christoph,

      sorry - but I'm still struggeling with it:

      Your blog describes how to connect hosts (instead of technical systems) via SAPOSCOL into the LMDB. In the second half you describe how to fully register a SAP HANA DB.

      "Client system" is kind of confusing because "clients" (like 000; 066...) and "systems" (like technical systems) are already used differently in the SAP'S language.

      BR, Tim

      Good stuff. Will give it a try. Thanks for posting.
