AutoConfig could not successfully execute the following scripts:
    Directory: /u01/apps/mine/inst/apps/test_mine/admin/install
      adadmprf.sh             INSTE8_PRF         1 

Solution:

1. select applications_system_name from applsys.fnd_product_groups; 

This will return the source instance sid.

2. Update the entry with target instance name:

 update applsys.fnd_product_groups set applications_system_name = '<target instance>'; 

3. Run autoconfig again.
