How to Resolve “ORA-29548: Java system class reported” in 12c?

Hello,

After applying PSU to 12.1.0.2.0, the application gets following error.

[Error] Execution (1: 1): ORA-29548: Java system class reported: release of classes.bin in the database does not match that of the oracle executable
ORA-06512: at “MDSYS.SDO_JAVA_STP”, line 370
ORA-06512: at “MDSYS.SDO_UTIL”, line 3188
ORA-06512: at “MDSYS.SDO_UTIL”, line 3211

When I checked the alert log file, it puts following messages.

joxcsys: release mismatch 12.1.0.2.160719 1.6 in database (classes.bin) vs 12.1.0.2.0 1.7 in executable

I checked any INVALID objects. But everything was OK. I did a small test about Java.

SQL> select dbms_java.get_jdk_version() from dual
*
ERROR at line 1:
ORA-29548: Java system class reported: release of classes.bin in the database
does not match that of the oracle executable

There was a problem with my java. Don’t worry about that there is a solution. Please run below script as sysdba.

SQL> @?/javavm/install/update_javavm_db.sql
SQL> SET FEEDBACK 1
SQL> SET NUMWIDTH 10
SQL> SET LINESIZE 80
SQL> SET TRIMSPOOL ON
SQL> SET TAB OFF
SQL> SET PAGESIZE 100

Session altered.

Now, let’s do a test again.

SQL> select dbms_java.get_jdk_version() from dual;

DBMS_JAVA.GET_JDK_VERSION()
——————————————————————————–
1.7.0_51

1 row selected.

SQL> select dbms_java.longname(‘TEST’) from dual
2 ;

DBMS_JAVA.LONGNAME(‘TEST’)
——————————————————————————–
TEST

1 row selected.

Hımm. It looks good. My application is also running.
