JSPM and Safe mode

I recently applied NW 7.02 SP12 and found that once all components were deployed my JSPM screen was frozen at "A Dispatcher is running".  I noticed at the unix level it had swithed to safe mode and this process actually took longer than the 90 minutes to deploy the components.

Is there any documentation on how long this is supposed to take?  Or, for that matter some sort of heartbeat I can monitor.  I found several logs but they didn't give me a comforatable feeling that JSPM was ok.

regards,

Dan Mead

    Hi Daniel ,

    When you deploy through JSPM , it will perform the activity in SAFE Mode.

    Suppose you have 3 server node , then in safe mode it will utilize only one server node other server node will not work. Thus it minimize the resource utilisation.

    Parameter for safe mode :

    In instance.properties file, you need to change the parameter instance.runMode=normal to run the server in normal mode.

      Hi Daniel,

      Don't change the parameter

      , just monitor the server node , whether they are getting restarted after the deployment.If you change the parameter , then some inconsistency will appear between the .SCA files because you have to restart the SAP System which may put you in trouble.

      Monitor the server node and checked whether server nodes are  getting restarted properly.Morever it will take long time in safe mode.

      you can also check the cpu utilization and memory utilisation as well.

      stop the ccms agent on the corresponding system if any running

      With Regards

    Hi Daniel,

    Hope you are doing good.

    There is no particular log apart from the JSPM log. The j2ee server goes to safe mode to reduce the number of running applications and to facilitate the deployment (mainly offline ones).

    The time depends on the usage types being used, but core ones should not take more than 2-3 hours.

    Do monitor the logs continuously:

    /usr/sap/<SID>/JC<nr>/work/dev*, std*, jvm*, deploy* files

    /usr/sap/<SID>/JC<nr>/j2ee/cluster/server0/logs/default trace (latest).

    /usr/sap/<SID>/<Central instance name>/j2ee/JSPM/log directory

    and

    /usr/sap/<SID>/JC<nr>/SDM/program/log

    Thank you and have a nice day :).

    Hi Daniel

    Open the configtool and in file tab u find an option Safemode please click on that and check whether it is in On state for the server nodes.if it is on for any server node please change to OFF ,restart your server.

    Thanks
