Compiling an Unfreezing Script
Example unfreezing script named appexample_unfreeze.sh:
#!/bin/sh AGENT_ROOT_PATH=$1 #The root directory required when the Agent invokes the script. Functions, such as log functions, will use this variable. Do not rename this directory. PID=$2 #The PID required when the Agent invokes the script. It is used for command output. Do not rename it. . "${AGENT_ROOT_PATH}/bin/agent_func.sh"#Reference script framework, which provides functions, such as logging, encryption, and decryption #Result processing function, which writes operation results into given files for invokers to obtain return values. # Input parameter. $1: 0 indicates a success; 1 indicates a failure. # No return value #RESULT_FILE is defined in agent_func.sh. function ExitWithResult() { Log "[INFO]:Freeze result is $1." echo $1 > ${RESULT_FILE} chmod 666 ${RESULT_FILE} exit $1 } function Main() { Log "*********************************************************************" Log "[INFO]:Begin to freeze appexample." #Check whether appexample exists. If not, 0 is returned and the script exits. #In the process of unfreezing I/Os, the Agent program invokes each unfreezing script in sequence. If any script fails to be invoked, the whole process fails. To avoid interference from other programs, 0 should be returned when appexample cannot be found. which appexample if [ $? -ne 0 ] then Log "[INFO]:appexample is not installed." ExitWithResult 0 fi #Invoke the actual unfreezing command. appexample -unfreeze if [ $? -ne 0 ] then Log "[INFO]:appexample freeze failed." #Unfreezing failed. Record the result and exit. ExitWithResult 1 fi Log "[INFO]:Freeze appexample. success" #Unfreezing successful. Record the result and exit. ExitWithResult 0 } Main
