i have upgraded oracle version ( 126.96.36.199 )of solution manager 7.1 SP14 system to 12c successfully.
ABAP started but java was unable to start due to JDBC issue.
i got error log in bootstrap folder
ORA-28040: No matching authentication protocol.
JDBC version is ojdbc14.jar ( java_class_archive.jar )
ABAP and Java worked before upgrade with 12x client.
after 12c only java had issue.
kindly suggest us.
