  1. Login to collabn1 as the oracle user and open a terminal.
  2. Run CVU to validate that you're ready to install CRS. Use the new “fixup” feature of 11gR2 CVU to create a script that can fix missing parameters. [oracle@collabn1 ~]$ /mnt/cdrom*/grid/runcluvfy.sh stage -pre crsinst -n collabn1,collabn2 -fixup -r 11gR2 Performing pre-checks for cluster services setup Checking node reachability... Node reachability check passed from node "collabn1" Checking user equivalence... User equivalence check passed for user "oracle" Checking node connectivity... Checking hosts config file... Verification of the hosts config file successful Node connectivity passed for subnet "192.168.78.0" with node(s) collabn2,collabn1 TCP connectivity check passed for subnet "192.168.78.0" Node connectivity passed for subnet "172.16.100.0" with node(s) collabn2,collabn1 TCP connectivity check passed for subnet "172.16.100.0" Interfaces found on subnet "192.168.78.0" that are likely candidates for VIP are: collabn2 eth0:192.168.78.52 collabn1 eth0:192.168.78.51 Interfaces found on subnet "172.16.100.0" that are likely candidates for a private interconnect are: collabn2 eth1:172.16.100.52 collabn1 eth1:172.16.100.51 Node connectivity check passed Total memory check failed Check failed on nodes: collabn2,collabn1 Available memory check passed Swap space check failed Free disk space check passed for "collabn2:/tmp" Free disk space check passed for "collabn1:/tmp" User existence check passed for "oracle" Group existence check passed for "oinstall" Group existence check passed for "dba" Membership check for user "oracle" in group "oinstall" [as Primary] passed Membership check for user "oracle" in group "dba" passed Run level check passed Hard limits check passed for "maximum open file descriptors" Soft limits check passed for "maximum open file descriptors" Hard limits check passed for "maximum user processes" Soft limits check passed for "maximum user processes" System architecture check passed Kernel version check passed Kernel parameter check passed for "semmsl" Kernel parameter check passed for "semmns" Kernel parameter check passed for "semopm" Kernel parameter check passed for "semmni" Kernel parameter check passed for "shmmax" Kernel parameter check passed for "shmmni" Kernel parameter check passed for "shmall" Kernel parameter check failed for "file-max" Check failed on nodes: collabn2,collabn1 Kernel parameter check passed for "ip_local_port_range" Kernel parameter check passed for "rmem_default" Kernel parameter check passed for "rmem_max" Kernel parameter check passed for "wmem_default" Kernel parameter check failed for "wmem_max" Check failed on nodes: collabn2,collabn1 Kernel parameter check failed for "aio-max-nr" Check failed on nodes: collabn2,collabn1 Package existence check passed for "make-3.81" Package existence check passed for "binutils-2.17.50.0.6" Package existence check passed for "gcc-4.1.2" Package existence check passed for "gcc-c++-4.1.2" Package existence check passed for "libgomp-4.1.2" Package existence check passed for "libaio-0.3.106" Package existence check passed for "glibc-2.5-24" Package existence check passed for "compat-libstdc++-33-3.2.3" Package existence check passed for "elfutils-libelf-0.125" Package existence check passed for "elfutils-libelf-devel-0.125" Package existence check passed for "glibc-common-2.5" Package existence check passed for "glibc-devel-2.5" Package existence check passed for "glibc-headers-2.5" Package existence check passed for "libaio-devel-0.3.106" Package existence check passed for "libgcc-4.1.2" Package existence check passed for "libstdc++-4.1.2" Package existence check passed for "libstdc++-devel-4.1.2" Package existence check passed for "sysstat-7.0.2" Package existence check passed for "unixODBC-2.2.11" Package existence check passed for "unixODBC-devel-2.2.11" Package existence check passed for "ksh-20060214" Check for multiple users with UID value 0 passed Current group ID check passed Core file name pattern consistency check passed. User "oracle" is not part of "root" group. Check passed Default user file creation mask check passed Starting Clock synchronization checks using Network Time Protocol(NTP)... NTP Configuration file check started... NTP Configuration file check passed Checking daemon liveness... Liveness check failed for "ntpd" Check failed on nodes: collabn2,collabn1 PRVF-5415 : Check to see if NTP daemon is running failed Clock synchronization check using Network Time Protocol(NTP) failed Fixup information has been generated for following node(s): collabn2,collabn1 Please run the following script on each node as "root" user to execute the fixups: '/tmp/CVU_11.2.0.1.0_oracle/runfixup.sh' Pre-check for cluster services setup was unsuccessful on all the nodes.
  3. Switch to the root user and run the fixup script on both nodes. collabn1:/home/oracle[RAC1]$ su - Password: -bash: oraenv: No such file or directory [root@collabn1 ~]# /tmp/CVU_11.2.0.1.0_oracle/runfixup.sh Response file being used is :/tmp/CVU_11.2.0.1.0_oracle/fixup.response Enable file being used is :/tmp/CVU_11.2.0.1.0_oracle/fixup.enable Log file location: /tmp/CVU_11.2.0.1.0_oracle/orarun.log Setting Kernel Parameters... fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.wmem_max=262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 [root@collabn1 ~]# ssh collabn2 /tmp/CVU_11.2.0.1.0_oracle/runfixup.sh root@collabn2's password: /root/.bashrc: line 16: oraenv: No such file or directory Response file being used is :/tmp/CVU_11.2.0.1.0_oracle/fixup.response Enable file being used is :/tmp/CVU_11.2.0.1.0_oracle/fixup.enable Log file location: /tmp/CVU_11.2.0.1.0_oracle/orarun.log Setting Kernel Parameters... fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.wmem_max=262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576
  4. As the oracle user, run CVU again to make sure the fixit script worked. The NTP, memory and swap checks might fail – but this is acceptable for our VMware test cluster. [root@collabn1 ~]# exit logout collabn1:/home/oracle[RAC1]$ /mnt/cdrom*/grid/runcluvfy.sh stage -pre crsinst -n collabn1,collabn2 -r 11gR2 ... Total memory check failed ... Swap space check failed ... Kernel parameter check passed for "file-max" ... Kernel parameter check passed for "wmem_max" Kernel parameter check passed for "aio-max-nr" ... Liveness check failed for "ntpd" ...
