 113 of the included audit checks require root privileged data collection . If sudo is not configured or the root password is  
 not available, audit checks which  require root privileged data collection can be skipped. 

1. Enter 1 if you will enter root password for each  host when prompted 
 2. Enter 2 if you have sudo configured for oracle user to execute script 
 3. Enter 3 to skip the root privileged collections 
 4. Enter 4 to exit and work with the SA to configure sudo  or to arrange for root access and run the tool later. 
 Please indicate your selection from one of the above options for root access[1-4][1]:-1 <=========Indicates the password input mode of user root. 1 indicates that the password will be entered manually.
Option 1: In the execution phase, enter the password of user root as prompted.
Option 2: Indicates that sudo is configured for user oracle.
Option 3: Skip the checks that require the permission of user root. This option is not recommended.
Option 4: Exit ORAchk to configure the root permission.
