Reset the locked SDM Password

Reset the locked SDM Password

The SDM password allows 3 logon attempts waiting for the correct password. Unfortunately if it is locked we cannot unlock the SDM password rather we would have to reset it. The below is the method to reset the SDM password. Logon to the Application server as <sid>adm

For Windows OS:

Open a command prompt and navigate to the folder <Drive>:\usr\sap[SID]\JC[sys-nr]\SDM\program such as D:\usr\sap\DVJ\JC51\SDM\program

Execute the below commands: 

StopServer.bat
sdm jstartup “mode=standalone”
sdm changepassword “newpassword=<Enterthenewpassword>”
sdm jstartup “mode=integrated”
StartServer.bat

For Unix OS:

Open a Telnet window and navigate to the folder /usr/sap/[SID]/JC[sys-nr]/SDM/program such as /usr/sap/DVJ/JC51/SDM/program

Execute the below commands: 

./StopServer.sh
./sdm.sh jstartup “mode=standalone”
./sdm.sh changepassword “newpassword=<Enterthenewpassword>”
./sdm.sh jstartup “mode=integrated”
./StartServer.sh 

Post processing (for Unix or Windows):

You must change the password in the config tool. If you forget that step, you will not be able to deploy using SDM. SAP note 701654 explains the process:

Use the Config Tool to change the entry in secure storage as follows:

           (Execute <SAPj2eeEngine_install_dir> \configtool\configtool.bat.)
secure store
           The configuration for the secure storage in the file system appears.
admin/password/<SID>  (enter the password for J2EE_ADM_[SID], not the SDM password)

click on the SAVE button.

           Note: Contrary to the message that appears, you do not need to restart the server or cluster for this change to take effect.
