SRVCTL For RAC

• srvctl enable asm -n node_name [-i ] asm_instance_name
  
  
  Use the following syntax to disable an ASM instance:
  
  
  srvctl disable asm -n node_name [-i asm_instance_name]
  
  The above statement is generally required when u want to disable the asm so that asm does not start automatically on reboot.
  
  You can also use SRVCTL to start, stop, and obtain the status of an ASM instance as in the following examples.
  
  
  
  Use the following syntax to start an ASM instance:
  
  srvctl start asm -n node_name [-i asm_instance_name] [-o start_options] [-c | -q]
  
  
  
  Use the following syntax to stop an ASM instance:
  
  srvctl stop asm -n node_name [-i asm_instance_name] [-o stop_options] [-c | -q]
  
  
  
  Use the following syntax to show the configuration of an ASM instance:
  
  srvctl config asm -n node_name
  
  
  
  Use the following syntax to obtain the status of an ASM instance:
  
  srvctl status asm -n node_name
  
  
  
  Use the following syntax to stop the database on anyone of the nodes in an RAC environment:
  
  srvctl stop listener -n node_name
  
  srvctl stop instance -d -i -o immediate
  
  
  
  Use the following syntax to start the database on anyone of the nodes in an RAC environment:
  
  srvctl start listener -n node_name
  
  srvctl start instance -d -i -o immediate
  
  
  
  Use the following command to stop the database using single command:
  
  srvctl stop database -d -o immediate
  
  
  In order to stop the node applications like oracle vip,gsd, ons services ,use following commands
  
  srvctl stop nodeapps -n
  
  
  Similarly to start
  
  srvctl start nodeapps -n
  
  
  If u wish to trun srvm trace on which can be useful for diagnosisi during instance startup or shut dowm use following command:
  
  SRVM_TRACE=TRUE; export SRVM_TRACE
  
  srvctl stop asm -n -i +ASM1 -o immediate>srvctl_stop_asm.log
  
  Similarly
  
  srvctl stop instance -d db_name -i instance_name -o immediate > srvctl_stop_instance.log
