I have faced the same issue and resolved after setting Listener port number.
- In configtool -> secure store the connection string is pointing Listener port 1528
- When I check in Listener.ora and tnsnames.ora showing port 1527.
I adjusted both (Listener and tnsnames) file in /oracle/SID/112_64/network/admin and /usr/sap/SID/SYS/profile/oracle and changed port to 1528
Then I started Solman and my both ABAP and JAVA engine working fine now.
