    CRS-0184: Cannot communicate with the CRS daemon.

    778211
      Hi,

      I am facing error on 2 node rac.

      ./crsctl check crs
      Failure 1 contacting CSS daemon
      Cannot communicate with CRS
      Cannot communicate with EVM

      1ogr2 rac
      linux el5

      i tried many ways to bring it up, but so far didnt succeed, i even rebooted the server..

      The linux team issued the command : service network restart

      since then crs is down on node 2. but up on node 1..

      i tried many work arounds no success.

      need help

      thanks

          Tell your SA to NEVER EVER EVER issue any start/stop/modiy command relating to ANY device in use by RAC. Period!!! And furthermore, NEVER EVER just "shutdown" the system without first taking down the DATABASE and RAC environment.

          Check to make sure that your OCR/VOTING devices have the correct permissions (oracle:dba 0660)
          Also make sure your network is still configured the way it was before issuing the reboot/restart commands.

          You cannot willy-nilly modify anything relating to the RAC environment without following the proper RAC procedures to do so.

            have you checked below logs?. hope you may get clues from those logs.

            $ORA_CRS_HOME/crs/log Contains trace files for the crs resources.you may get error details ....etc..
            $ORA_CRS_HOME/crs/init Contains trace files of the CRS daemon during startup and it may show any CRS login problems etc...
            $ORA_CRS_HOME/css/log The Cluster Synchronization (CSS) logs indicate all actions such as reconfigurations, missed check-ins, connects, and disconnects from the
            client CSS listener. In some cases, the logger logs messages with the category of auth.crit for the reboots done by Oracle. This could be used for checking the exact time when the reboot occurred.
            $ORA_CRS_HOME/css/init Contains core dumps from the Oracle Cluster Synchronization Service daemon (OCSSd) and the process ID (PID) for the CSS daemon whose
            death is treated as fatal. If abnormal restarts for CSS exist, the core files will have the format of core..etc...
            $ORA_CRS_HOME/srvm/log Log files for Oracle Cluster Registry , which contains the details at the Oracle cluster level.
            $ORA_CRS_HOME//log Log files cluster alert log, which contains diagnostic messages at the Oracle cluster level. This is available from Oracle database 10g r2.

              have you removed manually any tmpfiles...where /tmp/.oracle, /usr/tmp/.oracle or /var/tmp/.oracle please confirm.
