Oracle 19c has been released for almost a year, it has been installed on AIX and Linux a lot, and installation methods have emerged one after another. the most commonly used is graphical, which can avoid problems that can not be found by silent installation. Today, I helped a friend install oracle 19c rac. When I was performing root.sh, I reported an error. The following is a detailed analysis:

Execute root.sh, and the screen prints the log, which shows that an error failed was reported during the installation of acfs.

If we search failed directly, we can see that the relevant error reports are:

From this error message, we can probably see that the installation failed because ACFS found the previous version during the installation process, reported an error in the uninstall process, and was unable to install the new acfs.

Looking at mos, I found an article similar to this, but with a different version: AIX: ROOT.SH FAILS WITH CLSRSC-196: ACFS DRIVER INSTALL ACTIONS FAILED (Doc ID 1929899.1).

Upon inquiry, this platform is AIX, the previous installation of 12.2.0.2, installation 19c does not have a machine, so rm-rf $GRID_HOME, directly delete the relevant directory to uninstall, do not use the normal uninstall command. It may cause residue in the file, which can lead to failure. According to mos's solution:

Manually remove the driver files as root user:

Copy the following files from / usm/install/cmds/bin to / usr/lib/methods/, overwriting the existing ones:

# cd / usm/install/cmds/bin

# cp cfgacfsctl.bin cfgadvmctl.bin cfgadvmvol.bin defacfsctl.bin defadvmctl.bin ucfgacfsctl.bin ucfgadvmctl.bin ucfgadvmvol.bin udefacfsctl.bin udefadvmctl.bin / usr/lib/methods/

Modify the following files: / usr/lib/methods/ucfgacfsctl, / usr/lib/methods/ucfgadvmctl, / usr/lib/methods/udefacfsctl, / usr/lib/methods/udefadvmctl, change "ORA_CRS_HOME=" from old 11.2 GRID_HOME to 12.1 GRID_HOME

Run the following commands to complete deinstallation of old ACFS version:

# / usr/lib/methods/ucfgacfsctl-l ofsctl (Continue if error states "failed to look up ODM CuDv object class" or "device is already unconfigured")

# / usr/lib/methods/ucfgadvmctl-l advmctl (Continue if error states "failed to look up ODM CuDv object class" or "device is already unconfigured")

# / usr/lib/methods/udefacfsctl-l ofsctl (Continue if error states "failed to look up ODM CuDv object class")

# / usr/lib/methods/udefadvmctl-l advmctl (Continue if error states "failed to look up ODM CuDv object class")

# / usr/sbin/rmauth-h oracle

# rmrole oracle_devmgmt

# setkst

# rm / usr/lib/drivers/oracle

# rm / usr/lib/methods/advm / usr/lib/methods/acfs

# rm-rf / sbin/helpers/acfs

# rm / usr/sbin/acfsutil / usr/sbin/advmutil

# rm / sbin/acfsutil / sbin/advmutil*

The details of implementation are as follows:

By comparing with the first picture, we can see: libhasgen12.so. What is shown here is a missing version of 12, so you should be looking for a residual version of oracle 12c rac that was previously installed. When uninstalling, libhasgen19.so found another version 19. So it can be distinguished by version here.

Re-execute root.sh error resolution.

So when you uninstall oracle in the future, be sure to follow the official recommended uninstall method. Refer to the following articles for details
