For every connection, set the configuration details from details taken before;

Delete all the Jco connections for the <SOURCE_PI> System (*_<SOURCE_SID>), replacing them with connections for <TARGET_PI>.

Access “SLD Data Supplier Destinations” (Netweaver admin: Configuration Management--&gt;Connectivity--&gt;Destinations). 

Update all connections with the data saved prior to the refresh.  Use the ping option to test each connection

Check the connections in the ABAP engine using transaction SMGW (Goto --&gt; Logged on Clients)

Secure store Key Phrase

Below command is required to see secure store key phrase during Java export.
If we don’t have the key phrase, the export taken is of no use.
This is the most pre-requisite for Java migration (export/import) procedure.

Check the key phrase as follows;

Login to <SOURCE_PI> as user <s_sidadm>

cd <Global directory>

Execute below command from the global directory

/sltools/checkKeyPhrase.sh -f /security/data/SecStore.properties

Enter the phrase when prompted and you ought to get the message "The key phrase is correct." if you've got entered the right value

SAP Host agent auto upgrade procedure

We should maintain latest version of saphostagent in sap environment as solman gets the info from satellite systems wit the assistance of saphostagent.

This topic is to point out the feature to upgrade saphost agent automatically without manual intervention.
Only thing is we'd like to form sure the SAR file is downloaded and staged within the auto_upgrade directory.

Procedure to enable Auto-Upgrade feature for SAP Hostagent

SAP Hostagent has an auto upgrade feature which may be enabled as per note 1473974.


Please add the subsequent Parameters to SAP Hostagent Profile file for Linux (/usr/sap/hostctrl/exe/host_profile).


hostexec/autoupgrade_delay = 1440

DIR_NEW = //SAP/SAPHOSTAGENT/Linux/auto_upgrade

service/EnableRemoteDeployment = true

service/protectedwebmethods = NONE


1440 in hostexec/autoupgrade_delay is mentioned in minutes which translates to 24 hours (24*60 = 1440)


For Windows and HP-UX, use below paths present.

*DIR_NEW=//SAP/SAPHOSTAGENT/HP-UX/auto_upgrade

*DIR_NEW=//SAP/SAPHOSTAGENT/Windows/auto_upgrade


Note: Please restart Hostagent with below command for the parameters to require effect.


As root

Change to below dir

/usr/sap/hostcontrol/exe

./saphostexec -restart


If these parameters are activated, Hostagent automatically takes care of the upgrade by checking the trail mentioned in DIR_NEW and initiated an upgrade automatically when there's a replacement version available in this directory.
