You get an error while upgrading Oracle from 11g to 12c.
Error: File not found D:\oracle\product\220.127.116.11\db_1\demo\schema\mkplug.sql
File not found D:\oracle\product\18.104.22.168\db_1\demo\schema\mkplug.sql
You may be using the Enterprise response files rather than the Standard edition response files. There are two response files. One from Symantec and one from Oracle. Both of these should be in our 15.x Platform download called "22.214.171.124_64_bit_Installation_Tools.zip"; When unpacking the DLP Platform download file is located under ...\Symantec_DLP_15.5_Platform_Win-IN_126.96.36.19918\DLP\15.5\New_Installs\Oracle_Configuration. Inside this zip file are two response files that are used at different points in our guide to upgrading Oracle 11g to 12c. Please make sure you are using the correct response files as stated in the guide (https://www.symantec.com/docs/DOC10713), one for the Oracle Standard or Enterprise edition.
Downloaded Oracle files were not unzipped properly.
Upgrading from Oracle 11g to 12c Standard Edition
For 1st and 2nd causes:
Note: in any case, reinstalling Oracle from Scratch is required, and Oracle will override files so no need to delete them. Also, assumption for the installation files path is c:\temp\Oracle
Download the Symantec_DLP_15.5_Platform_Win-IN_188.8.131.5218. zip or Symantec_DLP_15.5_Platform_Lin-IN_184.108.40.20618. zip from the customer support portal https://mysymantec.force.com/customer/s/.
Unpack the Platform zip file and find the 220.127.116.11_64_bit_Installation_Tools.zip under the ...\Symantec_DLP_15.5_Platform_Win-IN_18.104.22.16818\DLP\15.5\New_Installs\Oracle_Configuration path. Move the file 22.214.171.124_64_bit_Installation_Tools.zip to a C:\temp folder (or any temporary folder) and unzip it. Copy all files to c:\temp\oracle\tools as instructed by our documentation (it can be D:\temp\oracle\tools or any other drive, for instance).
There are two response files that are used at different points in our guide to upgrading Oracle 11g to 12c. Please make sure you are using the correct response files as stated in the guide (https://www.symantec.com/docs/DOC10713). For instance, if installing/upgrading Oracle Standard edition, use the following command:
c:\temp\>D:\temp\Oracle\database\setup.exe -noconfig -responsefile c:\temp\Oracle\tools\responsefiles\Oracle_126.96.36.199_Standard_Edition_Installation_WIN.rsp
If you are upgrading Oracle Enterprise then the response file will be called "Oracle_188.8.131.52_Enterprise_Edition_Installation_WIN.rsp."
For 3rd Cause
Unpack the response files the same way as previous solution.
Unpack Oracle_184.108.40.206.0_Server_Win64_1of2 in a temporary folder and go all the way to \Downloads\Oracle_220.127.116.11.0_Server_Win64_1of2\DLP\Oracle_12gR2_Win\Oracle_18.104.22.168.0_64bit_Server_Win and copy the win64_22.214.171.124_database_1of2.zip and paste it in a short path folder such as c:\temp\unpackedOracleFiles\.
Unpack the win64_126.96.36.199_database_1of2.zip again and use the default path to unzip it this time. Find the ..\win64_188.8.131.52_database_1of2\database folder and copy all the files (CTRL + A, CTRL+C) and paste them in c:\temp\oracle\database, according to our installation/upgrade guide.
Unpack Oracle_184.108.40.206.0_Server_Win64_2of2 and go all the way to C:\Users\Administrator\Downloads\Oracle_220.127.116.11.0_Server_Win64_2of2\DLP\Oracle_12gR2_Win\Oracle_18.104.22.168.0_64bit_Server_Win and copy the win64_22.214.171.124_database_2of2.zip and paste it in a short path folder such as c:\temp\unpackedOracleFiles. Find the ..\win64_126.96.36.199_database_2of2\database\stage\Components and Copy all files (CTRL+A and CTRL+C), Paste them into C:\temp\oracle\database\stage\Components.
Now all Oracle files should be ready for the installation. See attached picture to make sure all files are in the right place before running the setup.exe to install Oracle again.
