Chapter 1 Introduction
Welcome to “How to Configure Replication between two SAP HANA cockpit Step-by-Step Guide” for SAP HANA
Platform Edition 2.0 On-Premise. In this whitepaper we will introduce you to all the requirements that are
needed in order to configure replication between two SAP HANA cockpit.
In this whitepaper we will discuss and show the user how to create and configure the environment:
• Prepare the environments
• How to enable replication
Overview of the Architecture
Before we can start our configuration, we need to look at the Architecture that this whitepaper will address. This
whitepaper will cover the following scenario:
Figure 1 Replication Architect
6
1. In the figure above, it is the general architecture implementation to replicate two SAP HANA cockpit.
a) We have one node which we will call it the “Headquarter”. That node will be the primary node
b) Another node which we will call “Waterloo”. That node will be the secondary node
2. We have to enable replication on the primary and replicates everything to the secondary
Note
This whitepaper is meant to show the administrator the minimum
steps that are needed in order to enable replication between two
SAP HANA cockpit.
Prerequisites
There are few requirements that must be met:
• Make sure the machines or VMs are backed up before starting the configuration in case anything goes
wrong, the administrator should be able to restore it back
• The primary and secondary systems are both installed and configured successfully. You have verified
that both are independently up and running after restarting them successfully
• This replication is done between two nodes only. No third tier is involved
• The number of nodes in secondary system must be equaled to the number of active nodes in the
primary system
• All configuration steps have to be executed on the master name server node; for SAP HANA Multitenant
Database Containers this means on the system DB (and not on the tenant DBS)
• The SAP HANA software version of the secondary has to be equal to or newer than the one on the
primary
• The secondary system must have the same SAP System ID, <SID>, and instance number as the primary
system. The primary replicates all relevant license information to the secondary
• System replication between two systems on the same host is not supported
• Changes to the ini file configuration parameters made on one system should be duplicated on the other
system. Note: Enabled the ini parameter replication on the primary site with [inifile_checker]/replicate =
true (from the “How To Perform System Replication for SAP HANA, in the help:
https://help.sap.com/viewer/4e9b18c116aa42fc84c7dbfd02111aba/2.0.04/en-
US/f65a9c62f60f4d4bb91620dd959ee68d.html?q=ini%20file%20checker
• An initial data backup or snapshot must be performed on the primary before the system replication can
be activated
Note
For more details in depth about replications, please refer to this following
detailed whitepaper:

Requirements
This setup should be done in a testing/development environment before it can be used and implemented in
production.
The architecture above is implemented in the following environment
Primary Node Secondary Node
• Host: cocpithost1 • Host: cockpithost2
• OS: SUSE SP15 PL01 • OS: SUSE SP15 PL01
• Site Name: Headquarter • Site Name: Waterloo
• Instance: 96 (Default) • Instance: 96 (Default)
• SID: H4C (Default) • SID: H4C (Default)
• OS: SUE Linux 15 SP01 • OS: SUSE Linux 15 SP01
• Port to be opened:39633 • Port to be opened:39633
Wildcard DNS: *.<YOUR-FQDN>
Web Dispatcher
Architecture Requirement
In order to enable replication between the two nodes or SAP HANA cockpit servers and be able to failover to the
other node or the secondary and be able to use it, we need to update the architecture in order to support
wildecard DNS. So that you must have *.<FQDN> available. Please refer to the architect below
8
1. Wildcard FQDN
2. Firewall
3. SAP Web Dispatcher to route the request
4. SAP HANA Database Cockpit which will be our headquarter with a role “Primary”
5. Replication between the “Primary” and the secondary SAP HANA Database Cockpit
Assumption
This whitepaper assumes the followings:
1. A wildcard domain available. So for example, if I have this domain, mycompany.net, then when you
issue from the command line ping command as follow, ping anything.mycompany.net, you should get
back a successful response. You cannot continue with this whitepaper before making sure this is setup
successfully
2. An SAP Web Dispatcher must be available and configured successfully. This whitepaper will only provide
the section configuration that is needed to enable Web Dispatcher to reroute the requests to the
appropriate SAP HANA cockpit
3. Two machines where Cockpits are not installed
4. This whitepaper will not discuss the installation and configuration of the SAP Web Dispatcher. For more
details about XSA failover, refer to this blog https://blogs.sap.com/2017/11/13/sap-hana-2.0-xs-
advanced-a-host-auto-failover-installationconfiguration-example/

Chapter 2 Installations and Configuration
Configuring SAP Web Dispatcher
As we mentioned, we assume the SAP Web Dispatcher is working successfully. Therefore, we need to add the
following configuration to your web Dispatcher instance profile.
1. Shutdown your Web Dispatcher
2. Edit the profile file you are using
3. Add the following content:
a. icm/server_port_3 = PROT=ROUTER,PORT=39633,TIMEOUT=60
b. icmd/HTTP/max_request_size_KB=-1
c. icm/max_conn = 2000
d. wdisp/system_3 = NAME=H4C, SRCVHOST=*39633,
EXTSRV=https://<COCKPIT-PRIMARY-
HOST>:39633#MAIN_INSTANCE;https://<COCKPIT-SECONDARY-
HOST>:39633#FAILOVER_INSTANCE
e. wdisp/server_3 = NAME=MAIN_INSTANCE, LBJ=1, ACTIVE=1
f. wdisp/server_4 = NAME=FAILOVER_INSTANCE, LBJ=-2147483647,
ACTIVE=1
g. Save the changes
h. Restart the SAP Web Dispatcher
Installing the SAP HANA Cockpit Primary
Now that we have the Web Dispatcher configured. It is time to install our first SAP HANA Database Cockpit.
Before starting the installation of SAP HANA Database Cockpit primary node. There is one more thing we need to
be aware of.
Note
During the installation of the Cockpit, the installer will not give you the
options to change the routing mode nor the ability to specify the domain
name which is in our case is the wildcard domain.
10
In order to change the routing mode and provide the domain name of our FQDN, we need to do the following:
1. If the the media, SAR, file is not unzipped, issue the following command
./SAPCAR -manifest SIGNATURE.SMF -xvf <Cockpit-MEDIA>.SAR
2. Make a backup copy of the auto_install.cfg which is located under the following folder “/<MEDIA-
INSTALLATION-DIRECTORY>/HDB__LCM_LINUX_X86_64/configurations/auto_install.cfg
3. Using text editor, for example vi , open the file auto_install.cfg
4. Change xs_routing_mode=ports to xs_routing_mode=hostnames
5. Change xs_domain_name=USE_DEFAULT to xs_domain_name=<YOUR-DOMAIN-NAME>, for example
xs_domain_name=mydomain.net or whatever the name is
6. Save your changes
7. Now that that we changed the configuration file under the folder HDB__LCM_LINUX_X86_64, we need
to invoke the installer that is located in the root of the media installation. Invoke the installer as follow:
./hdblcm.sh
8. Accept the default installation assuming you made the changes to the auto_install.cfg
9. Once the installation is done at the end you will see something displayed like that
10. Open Chrome browser and enter the following URL:
https://hanacokpit-sap-cockpit-web-app.<YOUR-DOMAIN>:39633
Note
Assuming you accepted the default installation value and the instance is 96 did not
change and the SID is H4C
11
11. If Everything is going well, you will see something like that:
12. We are done with the Primary node installation
Installing the SAP HANA Cockpit Secondary
• Repeat the same installation steps we have done on the primary node or server
• Follow the same steps we have done to the primary, do them on the secondary
12
Chapter 3 Preparing the replication
between two SAP HANA Cockpit
Preparing the primary
In this section we will go through all the steps that are to prepare the primary server for the Cockpit in order to
enable replication.
Accessing the Cockpit on the Primary host/server
1. Login to your server
2. Open your Web browser, preferably Chrome
3. Type the cockpit URL address, in our case that would be the wildcard FQDN domain name
https://api.<FQDN>:39633
4. Click on hana-cockpit-admin as shown below:
Figure 2 HANA Cockpit Admin access
13
5. Enter COCKPIT_ADMIN user information and click Log On button
Figure 3 Logon XS Advanced screen
6. You will get the following Not Authorized warning screen
Figure 4 Not Authorized warning screen

9. Once we are successfully logged in into the SAP HANA cockpit Manager, click on Registered Resources if
the HANA Express Cockpit DB is not added.
Figure 7 Registering the resource
10. Click on the Register Resource button on the bottom of the screen
Figure 8 Adding a resource
16
11. Enter the information for the primary host name. In our example it is cockpithost1, as well the instance
number which is 96
Figure 9 Adding the cockpit information to manage it
12. Since we are not using encryption, deselect all the options, it should look like this below:
Figure 9 Encryption section
17
13. Click on Step 3
14. Enter the technical user in order to add the resource. In my example I am using SYSTEM user. If you do
not have the SYSTEM user, click the “Create New Technical User” in order to create a user.
Figure 10 Using technical or SYSTEM user to add the resource
15. Accept the default and click on Step 5
Figure 10 Using technical or SYSTEM user to add the resource
18
16. Accept the default and click on Review
Figure 11 Contact information
19
17. Review your configuration and click on Register
Figure 12 Review system configuration before adding it
20
18. Once the system is added, you should see the something similar to the screen below:
Figure 13 Resource details
19. On the bottom of the screen, click on Go to SAP HANA cockpit as shown below:
Figure 14 Detail screen of the node that is added
21
20. Once you are in the Cockpit, click on Resource Directory as shown below:
Figure 15 SAP HANA cockpit Resource Directory tile
22
21. Click on the Resource SYSTEMDB@H4C or whatever the name you chose
Figure 16 Resource section
22. If this is the first time you accessed your node and never logged into it through the Cockpit, you will be
presented with a logon screen. This one requires a database user as shown below. In our example, I am
going to use SYSTEM user to login with
Figure 17 Logon dialog box to HANA Express Edition DB
23
23. Under the System Overview, if replication has not been setup before, go to the Database Administration
and click on “Manage System configuration”
Figure 18 Manage system configuration
24. Under the search field, type log_mod and hit search
Figure 19 Search for log_mode
24
25. Once it is found, click on delete to remove it as shown below
Figure 20 Removing the overwrite value of log_mode
The end result should have only the default value of log_mode which is normal as shown below:
26. Once the log_mode is normal, now go back to the SYSTEM Overview screen and go to the System
Replication card and click on “Create a data backup to enable system replication”
Figure 21 Creating a data backup to enable replication
25
27. Click on Create Backup button
Figure 21 Creating backup
28. Accept the default and click Back Up
Figure 22 Performing backup of SAP HANA cockpit DB
26
29. Once backup is done, we should have something like that
Figure 23 Backup result
30. Go back to the home page of the Cockpit and click on
Figure 24 SAP HANA cockpit Home page
31. Next step we have to provide the credential for the <SID>adm in order for us to enable replication. Click
on the “Enter Credentials” link under SAP Control Credentials as shown below:
Figure 25 Host credential
27
32. Enter the user ID <SID>adm. For example in our case it is h4cadm and password, assuming this was not
changed and click on OK
Figure 26 Host OS credential
33. The end result, should look like the screen below:
Figure 27 Host OS credential information entered
Preparing the secondary
In this section we will go through all the steps that are required in order to prepare the secondary server for the
Cockpit.
Note
Note: All the resources will be replicated to the secondary via system
replication, you only have to register the secondary in the primary HANA
Cockpit. You can omit any configuration to the secondary. But it is good
practice to access the secondary and do the configuration to make sure it
is working properly.
28
1. Login to SAP HANA cockpit on the secondary
a. Before doing that we need to shutdown the primary node so the Web Dispatcher does not send
any requests to it
2. For example in our case that would be the URL: https://api.<FQDN>:39633 as shown below:
Figure 28 hana-cockpit-admin
3. Then follow all the same steps from step 1 until step 25 of the section “Preparing the Primary” above
on the secondary node. Once this is done, please continue the below steps
29
4. On the secondary node, click on the Resource Directory tile
Figure 29 SAP HANA Database Cockpit Home page
5. Add the Host control credential as shown below
Figure 30 Host control credential
30
6. Enter the <SID>adm use id and password and click on OK
Figure 31 Host OS Credentials for SAP Control
31
Chapter 3 Configuring Replication
In this chapter we will focus on how to configure replication between two SAP HANA Database Cockpits.
Copying SSFS and xscontroller.ini
Now that we have prepared both systems. Now we are ready to start configuring replication.
There are few requirements that must be done at this stage. The following files below MUST BE COPIED FROM
the primary node to the secondary node and replace the existing ones in the secondary node with the ones from
the primary. Make sure you have a backup copy of the VMS or systems before moving forward.
These files are listed below:
• In HANA 2.0 the System PKI SSFS key and data files must be copied from the primary to the secondary
site according to this SAP Note 2369981. These files are
1. /hana/shared/H4C/global/security/rsecssfs/data/SSFS_H4C.DAT
2. /hana/shared/H4C/global/security/rsecssfs/key/SSFS_H4C.KEY
• As well we need to copy the XSA Keys as well. For more information please refer to this SAP Note:
2300936
1. /hana/shared/H4C/global/xsa/security/ssfs/data/SSFS_H4C.DAT
2. /hana/shared/H4C/global/xsa/security/ssfs/key/SSFS_H4C.KEY
• Lastly we need to copy the /hana/shared/H4C/global/hdb/custom/config/xscontroller.ini
Note
At this stage, we need to make sure that secondary should not be
tried to be restarted. If it is running, keep it running.
32
Configuring the primary
Now that we are ready to configure the primary node, restart SAP HANA Database cockpit on the primary using
the command line and follow these steps on the primary server
1. From a Linux terminal and issue this command su - h4cadm ( assuming default SID is used)
2. HDB start
3. Once the database is up and running, login to SAP HANA cockpit Manager as shown below
Figure 32 hana-cockpit-admin
Note
• Make sure you start a fresh instance of Chrome and type the URL
of the SAP HANA Database Cockpit
• The hana-cockpit-admin will take between 3 to 7 minutes before
it can be accessed. So if you get the error 503 service not
available, just give it at least 5 to 7 minutes before it can be
ready. To check the status, check the Troubleshooting section
which explains how to monitor the starting process
33
4. Click on Registered Resources
Figure 33 Registered resources
5. Register the secondary Cockpit and follow the steps on how to register a node that we have done in the
section “Preparing the Primary”
34
6. Once these steps are done, we should have the primary and secondary added to the Cockpit as shown
below:
Figure 34 Systems managed by SAP HANA Database Cockpit on primary node
35
7. Go back to the primary SAP HANA Database Cockpit and click on “Resource Directory” tile
Figure 35 Accessing Resource Directory
Note
a. to access the Cockpit, click on this URL:
https://api.<FQDN>:39633
b. Select from the XSA bottom right screen “hana-cockpit”
36
8. Click on the Enter Credentials for the secondary node as shown below:
Figure 36 Secondary host OS credentials
9. Enter the credential which is <SID>adm of the secondary node and password
Figure 37 Host OS Credentials for SAP Control
10. Now click on the secondary Cockpit database as shown below
Figure 38 SAP HANA Database Cockpit Resources
37
11. Enter database user of the secondary node, in our example I am going to use SYSTEM as shown below
Figure 39 SAP HANA Database Cockpit user ID and password of the DB
12. Our setup now should look like this on the primary
Figure 40 Cockpit resources configuration
38
13. Click on SYSTEMDB@H4C for the primary node. Make sure it is the one for the primary
14. Click on System Replication card
Figure 41 System Replication
15. Click on Enable This System as Primary
Figure 42 Enabling the primary node to be a primary
39
16. Enter a name of your choice for your site. In my case I called it headquarter.
Note: Do not use names such as, PRIMARY, REMOTE or SECONDARY
Figure 43 System Details for replication site
17. Once it is done, click on Configure on the bottom right of the screen
18. Once the configuration is successful, we should have the following screen
Figure 44 Configure replication
19. Click on “Configure System Replication” Button
20. Fill the Tier 2 System Details as follow:
a. Site Name of the second tier, can be anything, in our case, it is called Waterloo
b. The secondary System Host, it is called cockpithost2. In your setup maybe it is called something
else. If you are not sure, click on the double squares on the right of the text field. It is called the
value help
c. Make sure you select the checkbox that says “The system has to be offline to register it as a
secondary…”
d. Replication Mode: You can select whatever is required for your application. In our test, we
chose Asynchronous
e. Operation Mode: We chose Log Replay
f. Initiate Data Shipping is set to No
g. Start the secondary system after registration is checked
40
h. Final result should look like the screen below
Figure 45 Replication configuration values
Note
Select the replication mode that satisfy your requirement. This paper
covers only a proof of concept of the replication. To learn more about
replication and the replication and operation mode. Please refer to the
following whitepaper https://archive.sap.com/kmuuid2/9049e009-

e14c277d84a3/How%20to%20Perform%20System%20Replication%20fo
r%20SAP%20HANA.pdf
41
21. Once you are done, click on Configure
Figure 46 Configuration of replication in progress...
42
22. Once it is done, it will look like this
Figure 47 Initial result of System Replication Overview
Note
The figure color is yellow and not green because the system
replication is in state “initializing”.
23. Give it few minutes and go back to the SAP HANA cockpit Home page still on the primary and click on
“Resource Directory” tile
Figure 48 Resource Directory
43
24. Click on SYSTEMDB@H4C that belongs to the primary as shown below
Figure 49 Listening of resources
25. Click on “System Replication” Card
Figure 50 System Replication card
44
26. We should see the following result. Which indicates replication is configured successfully
Figure 51 System Replication Overview summary

Chapter 6 Testing replication
Add a database
This is just a test use case, on the primary node add an instance of a database to be managed by the cockpit. Just
pick any instance of an existing database. Use the method that was described in this whitepaper.
Secondary taking over
To test now the replication, we need to do the following:
1. Login to the primary SAP HANA Database Cockpit using the following URL: https://api.<FQDN>:39633
2. Click on the Resource Directory tile
3. Click on the secondary database instance as shown below:
46
4. Click on System Replication card
47
5. Click on Take Over as shown below
6. Click on Start Takeover
48
7. You should see the following process is happening
8. If everything goes well, you should see the following
9. Click the Home button in Fiori launchpad
10. Now click back on the Resource Directory tile
11. You should see the following
12. Now the secondary took over and the replication is done
13. Assume the primary has a problem, shut it down by issuing HDB stop
49
14. Now open a new instance of Chrome and enter the URL https://api.<FQDN>:39633
15. Click on the bottom right on HANA Cockpit
16. If you get the error 503 Server not available, you need to wait at least 5 to 10 minutes before it can be
available.
17. Once XS engine is ready, you should see the following
18. Logon and you should see Fiori launchpad tiles listed
50
Chapter 7 Troubleshooting
Replication button is missing to configure replication
Issue:
When the user is trying to configure replication for the Cockpit, the user notices the button of replication
configuration is missing.
Resolution:
This issue is resolved in this
KBA: 2910382 - When using SAP HANA cockpit the replication buttons are missing
Tier 2 System register error: primary and secondary has different SystemKPI SSFS
Issue:
When trying to configure replication, the following error occurs.
Resolution:
The issue is the user forgot to copy the two SSFS files from these locations on the primary to the secondary
1. /hana/shared/H4C/global/security/rsecssfs/data/SSFS_H4C.DAT
2. /hana/shared/H4C/global/security/rsecssfs/key/SSFS_H4C.KEY
3. /hana/shared/H4C/global/xsa/security/ssfs/data/SSFS_H4C.DAT
4. /hana/shared/H4C/global/xsa/security/ssfs/key/SSFS_H4C.KEY
51
503 Service not available
Issue:
When starting SAP HANA Database Cockpit, the user is able to access the main XSA home page as follow
https://api.<FQDN>:39633, but when the user clicks on HANA-Cockpit link on the bottom right of the page, the
error 503 Service not available is displayed.
Resolution:
This is expected behavior because the Cockpit applications takes sometimes up to 10 minutes or more in order
to load. To monitor the load time and make sure everything is loading do the following:
1. On the machine that the Cockpit is restarted on open a Linux terminal
2. Issue su - h4cadm
3. Issue xs login
4. You should see something like this after login with the user COCKPIT_ADMIN
5. Now issue this command xs a
a. Check under the instances column, if the value is 0/1, that means the application still did not
load. In order to access the Admin Cockpit, cockpit-admin-web-app, the value of the instances
must be 1/1
b. Same things for the HANA Cockpit, check cockpit-web-app, 0/1
52
6. Wait sometimes and issue xs a again until you see this
7. Now open a new instance of Chrome assuming no web caching in place, issue this
URL: https://api.<FQDN>:39633
8. Access either one of the HANA-cockpit or HANA-cockpit-admin
9. You will be asked to login
10. Finally you should logged in successfully to the cockpit
Changes in file auto_install.cfg are not being applied during installation
Issue:
All the changes that are done in the file auto_install.cfg are not being taking into effect during the installation
Resolution:
If the changes are made to the following file, /<MEDIA-INSTALLATION-
DIRECTORY>/HDB__LCM_LINUX_X86_64/configurations/auto_install.cfg, and then you run the installer from
this directory, /<MEDIA-INSTALLATION-
DIRECTORY>/HDB_SERVER_LINUX_X86_64/configurations/auto_install.cfg , then any changes that are made to
the file, /<MEDIA-INSTALLATION-DIRECTORY>/HDB__LCM_LINUX_X86_64/configurations/auto_install.cfg, will
not be used during the installation. Therefore; If changes are made to the file located under
HDB_SERVER_LINUX_X86_64, then the user need to run the installer hdbinst under this folder. If the changes are
made to the file located under HDB__LCM_LINUX_X86_64, then hdbinst.sh needs to be ran.
