CertificateLabel (MQCHAR64)

This field gives details of the certificate label being used.

IBM MQ initializes the default value for the CertificateLabel field as blanks.

This is interpreted at runtime as the default value, and is backwards compatible.

For example, specifying a MQSCO version less than 5.0, or using the default value of blanks for the CertificateLabel field, uses the preexisting default value of ibmwebspheremquser_id.
