Oracle Database AWR error: ORA-06502 [How to Solve]

Oracle database AWR report is an important tool for DBA to analyze database performance!

Recently encountered a problem and reported an error:

ERROR:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "SYS.DBMS_WORKLOAD_REPOSITORY", line 919
ORA-06512: at line 1

So, how to solve this problem?

Solution:

update WRH$_SQLTEXT set sql_text = SUBSTR(sql_text, 1, 1000);
commit;

After execution, re execute sqlplus/as SYSDBA @/ RDMBS/admin/awrrpt. SQL script successfully generates AWR report!
