what can go wrong when installing oracle database RAC

TOP Note: Solutions for Typical 11gR2 Grid Infrastructure/RAC Database runInstaller Issues [ID 1056713.1]

Applies to:

Oracle Server - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.

Purpose

This note is to provide workaround/solution for common 11gR2 Grid Infrastructure runInstaller errors.

Details

P: [INS-06006] Passwordless SSH connectivity not set up between the following node(s): [node1, node2]. CVU may reports "PRVF-4007 : User equivalence check failed for user "user"" for same error

S: Possible causes:

• Grid user does not have password on OS level, the fix is to set password with "passwd" command.
• If OUI is able to setup passwordless SSH connectivity but still shows the error, likely "ping" command is inaccessible - grid user should be able to execute ping command.
• OS command ssh or scp are not in expected location, the workaround is to either create symbolic link on all nodes or export the following environment variables before starting OUI

ln -s /usr/local/bin/ssh /usr/bin/ssh
ln -s /usr/local/bin/scp /usr/bin/scp

OR

export ORACLE_SRVM_REMOTESHELL=/usr/local/bin/ssh
export ORACLE_SRVM_REMOTECOPY=/usr/local/bin/ssh

Note: /usr/local/bin is the location for ssh and scp, if ssh and scp are located in somewhere else, replace it accordingly

• For other causes and solutions, refer to note 1323714.1

P: [INS-6001] Failed to perform operation due to internal driver error
WARNING: Failed to establish SSH connectivity between the selected nodes.

S: Likely $HOME/.ssh or files in it are owned by different user.


P: [INS-40912] Virtual host name: node.domain is assigned to another system on the network.

S: Virtual host name should be unused and down as it's managed by CRS, "ping" can confirm


P: [INS-40719] IP address configured for Single Client Access Name (SCAN): node.domain is already assigned to another system

S: SCAN VIP should be unused and down as it's managed by CRS, ping can confirm


P: [INS-40931] The following nodes do not have interfaces configured on a subnet matching the SCAN VIP subnet: [node1.domain, node2.domain]

S: Public IP and SCAN VIP should be in same subnet


P: [INS-40724] No locally defined network interface matches the SCAN VIP subnet.

S: Public IP and SCAN VIP should be in same subnet, and public IP should be primary IP on a NIC.


P: [INS-40922] Invalid SCAN Name - unresolvable to IP address.

S: SCAN name should be resolvable, ping or nslookup can confirm


P: [INS-40718] Single Client Access Name (SCAN) name:scanclu could not be resolved.

S: SCAN name should be resolvable, ping or nslookup can confirm


P: [INS-40711] Cluster Name is blank

S: Refer to note 1395189.1 for solutions


P: [INS-40909] Host names from multiple domains entered.

S: Public hostname is on different domain than hostname, example: node1.us.oracle.com is hostname but node1.at.oracle.com is selected for public hostname


P: [INS-41703] The local node is not selected as one of the nodes for upgrade

S: Misconfiguration of hostname, refer to note 1399207.1 for solution


P: [INS-41815] The installer has detected that Oracle Clustrware 11.2.0.3 is not running on the following node ; PRCI-1108 failed to check CRS running status for CRS home /ocw/grid on node racnode2 ; PRCT- 1003 Failed to run crsctl on node "racnode2"

S: SSH user equivalence is broken due to bug 13620816, the workaround is to set permission of /opt/oracle to 755 on all nodes and click on "retry" in OUI, refer to note 1422423.1 and note 1399207.1 for more details


P: [INS-08109] Unexpected error occurred while validating inputs at state 'NetworkInterfaceUI'

S: If doing silent install, make sure network is specified properly with correct NIC name and subnet ID.  Refer to to validate. Example:

oracle.install.crs.config.privateInterconnects=bond0:10.20.122.0:1,bond2:192.168.0.0:2


P: [INS-08109] Unexpected error occurred while validating inputs at state 'InstallOptionsUI'

S: oratab has wrong ASM location, refer to note 1387974.1 for details


P: [INS-08101] Unexpected error while executing the action at state: 'performChecks'

S: Possible causes:

• "CRS=true" flag is set on wrong home, refer to note 1053393.1 for solution

• Misconfiguration of hostname, refer to note 1399208.1 for solution

P: [INS-41312] One or more locations specified for the Oracle Cluster Registry (OCR) cannot be used.

S: OCR location need to be writable by grid user, likely ownership and  permission of the OCR location is incorrect, use "ls -l ocr_loc" to find out.


P: [INS-30014] Unable to check whether the location specified is on CFS

S: OCR location need to be writable by grid user, likely ownership and  permission of the OCR location is incorrect, use "ls -l ocr_loc" to find out.


P: [INS-32026] The Software Location specified should not be under Oracle base location.

S: As Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location, it may create problems for subsequent installations or other operations into the same Oracle base.  The solution is to specify software location outside of Oracle base.


P: [INS-41514] One or more locations specified for placing voting disks cannot be used.

S: Voting location need to be writable by grid user, likely ownership and  permission of the voting location is incorrect, use "ls -l ocr_loc" to find out.


P: [INS-30516] Please specify unique disk groups.

S: If OCR and Voting Disks are stored in ASM, an new diskgroup with unused disks is needed.


P: [INS-40401] The Installer has detected a configured Oracle Clusterware home on the system.

S: Oracle Clusterware needs to be cleaned up completely before being installed again. To clean up, refer to


P: [INS-40406] The installer detects no existing Oracle Grid Infrastructure software on the system.

S: Possible causes:

• If the error happened during upgrade to 11gR2, likely it's due to "CRS=true" flag is missing or wrongly set on other than pre-11gR2 CRS home; refer to note 1053393.1 for solution

• If runInstaller is started from wrong Oracle Clusterware home (i.e., existing GI/CRS home), the error can also happen, the solution is to start from the correct home(i.e., the stage location)

P: [INS-40420] The current installation user is not the same as the installation owner of the existing Oracle Grid Infrastructure software.

S: 11gR2 GI must be installed by pre-upgrade CRS user as it's not allowed to change when upgrading. If the error happens even with the same user, likely it's due to bug 10075643 which is fixed in 11.2.0.2 Bundle1 and 11.2.0.3, refer to note 1322180.1 for workaround.


P: [INS-40421] The installer cannot detect the owner of the existing Oracle Grid Infrastructure home (Grid home).

S:
  -- Run the installer as the user owning the existing CRS/Grid home.
  -- If upgrading from pre-11.2, as crs user, "init.cssd user" should return correct crs user name. Location of init.cssd is /etc/init.d on Linux/Solaris, /etc on AIX and /sbin/init.d on hp-ux.
  -- If upgrading from earlier 11.2, grid user should be able to open olr.loc which is located in /etc/oracle on Linux and AIX, and /var/opt/oracle on Solaris and hp-ux.
  -- If upgrading from earlier 11.2, remove /var/tmp/<nodename>.olr.loc or /usr/tmp/<nodename>.olr.loc or /tmp/<nodename>.olr.loc before starting OUI


P: [INS-35351] Inconsistant Versions Detected.

S: Verify active version of clusterware (output of "$GRID_HOME/bin/crsctl query crs activeversion") is equal or higher than the database software that's being installed.
bug 12311806


P: [INS-35354] The system on which you are attempting to install Oracle RAC is not part of a valid cluster.

S: Verify whether Grid is healthy with "$GRID_HOME/bin/crsctl stat res -t -init", if so likely it's due to central inventory issue - refer to solution of note 1053393.1


P: [INS-13016] You have chosen to ignore some of the prerequisites for this installation. This may impact product configuration.

S: The message tells that some prerequisites are ignored, it's very important to meet all prerequisites before continue, only false positive should be ignored; search my oracle support or engage Oracle Support if there's any doubts.



P: [INS-13013] Target environment do not meet some mandatory requirements. Some of the mandatory prerequisites are not met. See logs for details. /tmp/OraInstall<timestamp>/installActions<timestamp>.log

S: Identify the list of failed prerequisite checks from the log: /tmp/OraInstall<timestamp>/installActions<timestamp>.log. Then either from the log file or from installation manual, or from my Oracle Support find the appropriate configuration to meet the prerequisites and fix it.



P: [INS-32091] Some of the configuration assistants failed.

S: Review installation log note 1056322.1 to find out the exact issue and fix it.


P: runInstaller is very slow

S: If happens on UNIX/Linux, refer to note 1367021.1, if on Windows, ensure Anti Virus software is turned off temporarily while the installation is running.
