I am trying to install Oracle 19c RAC on three nodes, running RHEL 8.3. GRID installation was ok. But, Oracle DB SW install using runInstaller(GUI) is stuck with this issue while checking for SSH connectivity between nodes.

Error Reported: Cause - Either passwordless SSH connectivity is not setup between specified node(s) or they are not reachable. Refer to the logs for more details. Action - Refer to the logs for more details or contact Oracle Support Services. More Details PRVF-5311 : File "/tmp/InstallActions2020-12-24_01-17-15PM/xyzsvr.getFileInfo184599.out" either does not exist or is not accessible on node "xyzsvr".

When I tried runcluvfy, it reports ok.

$ /u01/app/19.0.0/grid/runcluvfy.sh comp admprv -n xyzsvr1,xyzsvr2,xyzsvr3 -o user_equiv -sshonly -verbose

Verifying User Equivalence ... Node Name Status

xyzsvr2 passed xyzsvr3 passed

Verification of administrative privileges was successful.

CVU operation performed: administrative privileges Date: Dec 24, 2020 1:44:57 PM CVU home: /u01/app/19.0.0/grid/ User: oracle

There is nothing in Oracle support site.

Try below solution from https://dbaclass.com/article/upgrade-grid-infrastructure-from-oracle-12c-to-19c:

  • Find out where is the scp executable file is located and rename it:
    mv /usr/bin/scp /usr/bin/scp.orig
  • Create a new file:
    vi /usr/bin/scp
  • Add the below line to the new created file:
    /usr/bin/scp.orig -T $*
  • Change the file permission:
    chmod 555 /usr/bin/scp
  • Once installation is done, you can revert to the original:
    mv /usr/bin/scp.orig /usr/bin/scp

https://stackoverflow.com/questions/17900760/what-is-pseudo-tty-allocation-ssh-and-github explains the purpose of the -T parameter.
