SQLT XECUTE error out

Hello,

We have a Oracle 11.2.0.1.0 RAC DB on Linux 5.3. I need to update SR and in this environment, I have trouble with SQLT. I have installed it latest but when I try to use it (XECUTE) getting this error:

SQL> grant SQLT_USER_ROLE to NPCDB;

Grant succeeded.

SQL> START run/sqltxecute.sql input/upd_bad.sql

BEGIN

*

ERROR at line 1:

ORA-20110: User "NPCDB" lacks required "SQLT_USER_ROLE" role or SQLT is not properly installed.

Review installation NN_*.log files.

ORA-06512: at line 6

----

I uploaded install logs for your review.

Thanks in advance for your help.
