  3. Obtain and decompress install_dropcache.zip to a local directory. If FusionCube Builder is used to install software, the script is deployed by default.
  4. Open WinSCP, create a connection with the system, access the local directory where the decompressed file is located, right-click the script file, choose Upload from the shortcut menu, change the transfer mode to the binary mode, and click OK.
  5. After confirming that the script is successfully uploaded, run the following command as user root:

    [root@dbn02 ~]# sh install_dropcache.sh  
    INFO:drop cache scripts install success, /opt/dsware/dropcache.sh will run every 60 minutes; 
    [root@dbn02 ~]# crontab –l                    //Check whether the script is configured. 
    0 0 * * * sh /opt/omm/oma/tools/func/oma_check_log.sh & 
    * * * * * sh /opt/dsware/agent/script/dswareAgent_crontab_chk.sh >/dev/null 2>&1 & 
    * * * * * sh /opt/omm/oma/tools/oma_monitor >/dev/null 2>&1 &
