Length of value in MeasurementDataTrait

[lzmuda1]

Hi,

I have a question to Developers.

I want pass to  MeasurementDataTrait some String, longer than 255. But in org.rhq.core.domain.measurement.MeasurementDataTrait class, length of "value" is equal only 255.

    @Column(length = 255)

    private String value;

I have found in database, that size of value in the table RHQ_MEASUREMENT_DATA_TRAIT is equal 4000 BYTES. I suppose that size of "value" in class MeasurementDataTrait can be a bit bigger, for example 500. Am I right?

Is there any possibility that in the future RHQ releases,  size of "value" will be lengthened?

Regards,

Lukasz

probaby just a mismatch in the code. I would think that annotation can be increased to match the actual DB constraint.

Thanks for the quick reply. I don't want compile full RHQ project. Can I expect, in the close future, changes in MeasurementDataTrait class?

Yes the annotation attribute will be updated to match the value of the database initialization scripts. Still, IIRC the @Column length attribute is only used by Hibernate DDL generator, and will not prevent you from storing something larger (provided the database column can accept it)

I wrote plugin, and I use MeasurementDataTrait to pass some String, and in RHQ Desktop in traits I see full String, but in alerts sended to me, I see only 255 first characters, so I think when size of value will be lengthened my problem will dissapear. Thanks for your help.

Yeah, Thomas, I belive you are right. IIRC, that attribute is only used when you ask hibernate to initially create your schema. It isn't a validator on update or insert.
