When you specify an options record as a property of a WebSphere MQ record, you are referring to a variable that is based on a predefined BasicRecord part (such as MQOD). The part resides in an EGL file that is provided with the product, as described in WebSphere MQ message queue access. Instead of using the Record part as is, you can copy it into your own EGL file and customize it.
If you do not indicate that a given options record is in use, EGL builds a default record and assigns values, as described in the following sections. However, the default options records are not available when you access WebSphere MQ without using MQRecords.
Many of the values that are assigned to fields in these records are WebSphere MQ constants, such as MQOT_Q or MQOO_FAIL_IF_QUIESCING. There are hundreds of these constants, far too many to document here. For a complete list, see your WebSphere MQ documentation.
