find if a parameter is dynamic in HANA

We many times need to know whether a hana parameter is dynamic or a restart is required to make it effective. To check this goto below

  • open cdexe on the OS side, if you already configured this alias
  • otherwise go to the folder “cd /usr/sap/$SAPSYSTEMNAME/SYS/exe/hdb”
  • open the config folder by command “cd config”
  • open the Master ini files you need with the editor (do not adjust value in these files)
  • check the hint for the parameter you are looking for, there you will find configure online or offline

Example

Below files contains details about

  • Default values (not to be adjusted)
    • /usr/sap/<sid>/HDB<inst>/exe/config
    • /hana/shared/<sid>/HDB<inst>/exe/config
  • Valid for a specific service (e.g. indexserver) or component (e.g. multidb) on all hosts
    • /usr/sap/<sid>/SYS/global/hdb/custom/config/<service_or_component>.ini
    • /hana/shared/global/hdb/custom/config/<service_or_component>.ini
  • Valid for all services on all hosts
