Types of data item available in the MQAI

Data items are used by the IBM MQ Administration Interface (MQAI) to populate data bags when they are created. These data items can be user or system items.

These user items contain user data such as attributes of objects that are being administered. System items should be used for more control over the messages generated: for example, the generation of message headers. For more information about system items, see System items and the MQAI.

Types of Data Items

When we have created a data bag, we can populate it with integer or character-string items. We can inquire about all three types of item.

The data item can either be integer or character-string items. Here are the types of data item available within the MQAI:

• Integer
• 64-bit integer
• Integer filter
• Character-string
• String filter
• Byte string
• Byte string filter
• Bag handle

Use Data Items

These are the following ways of using data items:

• Counting data items.
• Delete data items.
• Add data items to bags with the MQAI.
• Filtering and querying data items.
