嵌套的异常是org.hibernate.exception.SQLGrammarException：ORA-02289：序列不存在

Question

EDIT:

@NamedQueries({
    @NamedQuery(name="getOLTsByProcessStateAndAssignee",query="select o from Olt o where o.activityProcessId IN(:procId) order by modifiedtime desc"),
    @NamedQuery(name="getOLTsByProcessStateAndAssigneeForSearch",query="select o from Olt o where o.activityProcessId IN(:procId) and o.name like :name order by modifiedtime desc"),
    @NamedQuery(name="findOltbyname",query="select o from Olt o where o.name=:oltname and o.jioCenter.id=:jioCenterId"),
 })
@XmlRootElement(name="Olt") @Audited @Entity
@Table(name="olt")
public class Olt extends BaseEntity implements Serializable
{
    /**
     * 
     */
    private static final long serialVersionUID = 1L;


    /*@GeneratedValue(generator="olt_id_gen")
    @GenericGenerator(name = "olt_id_gen",
        strategy = "com.inn.fttx.model.IntegerSequenceGenerator",
        parameters = {
            @Parameter(name="sequence" , value="OLT_ID_SEQ")
        })
    @Id  */



    @SequenceGenerator(name = "olt_id_SEQ", sequenceName = "olt_id_SEQ", allocationSize=1)
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="olt_id_SEQ")

here I am getting the following exception -

nested exception is org.hibernate.exception.SQLGrammarException: ORA-02289: sequence does not exist

I have seen different threads of coderanch and stackoverflow, what i found:

1. the Oracle database is running (Most likely)
2. you app is connected to it (Most likely)
3. You are connected to the correct database (Maybe/Maybe not)
4. There is actually a sequence table called "olt_id_SEQ"

I just pasted this points above, so i can show what I have done already.

But in my Oracle database, I have this sequence and i can perform select with nextval on it.

Please let me know, if trouble is from database side or java? Any suggestion/advice would be greatly appreciated.

Answer 1

If your statement There is actually a sequence table called "CUSTOMER_ID_sequence" makes no sense since your code is trying to reach the olt_id_SEQ sequence. And a sequence is not a table.

So there are two options here:

1 - The user you are using to connect to oracle does not have proper grants on that sequence olt_id_SEQ .

2 - You are using a wrong sequence in your code, since you mentioned it should be

 @SequenceGenerator(name = "CUSTOMER_ID_sequence", 
                    sequenceName = "CUSTOMER_ID_sequence", allocationSize=1)
 @GeneratedValue(strategy=GenerationType.SEQUENCE, 
                 generator="CUSTOMER_ID_sequence")

Edit

The OP edited his question but the problem here still are the same as I mentioned above.

1 - The user you are using to connect to oracle does not have proper grants on that sequence olt_id_SEQ or this sequence doesn't exists at all. To check that get the user and password that you use on your application and run this query:

select * from all_objects where object_name = 'OLT_ID_SEQ'

If this query do not return any row the sequence does not exist or it doesn't have a grant to it.

See what was the schema that is the owner of the sequence. If you are using an user that has limited permission you may need to use: [schemaName].olt_id_SEQ or create a public synonim to this sequence.

Answer 2

My problem is solved now. Hibernate was using a sequence automatically. So I provided the grant to that sequence now its working.
