What is TDQ in CICS?
TDQ may be used by batch or online applications. TDQ can automatically trigger a CICS transaction which is called as ATI (Automatic Task Initialization). If trigger level defined as n, it triggers the transaction associated with it after nth record is written to TDQ.
What are the two types of TDQ?
Types of TDQ There are two types. One is intra-partition and other one is extra-partition.
What is temporary storage queue in CICS?
Temporary storage is the primary CICS® facility for storing data that must be available to multiple transactions. If a queue contains only a single item, it can be thought of as a named scratchpad area. Temporary storage queues are identified by symbolic names of up to 16 characters.
What does TDQ mean?
text-dependent question
On the surface, a text-dependent question (TDQ) is simply a question whose answer can be derived directly from information in the supporting text.
What is the purpose of GDG?
A generation data group (GDG) is a collection of historically related non-VSAM data sets that are arranged in chronological order. That is, each data set is historically related to the others in the group. Within a GDG, the generations can have like or unlike DCB attributes and data set organizations.
What is the use of TSQ in CICS?
Temporary Storage Queue (TSQ) is a feature that is provided by the Temporary Storage Control Program (TSP). A TSQ is a queue of records that can be created, read and deleted by different tasks or programs in the same CICS region. A queue identifier is used to identify TSQ.
How do you respond to TDQ?
- Understand the constructed response question.
- Use text features and clue words to find evidence in a text.
- Record evidence in a text.
- Organize evidence and make a plan for written response.

How do I write a good TDQ?
Text-dependent questions typically begin by exploring specific words, details, and arguments, and then move on to examine the impact of those specifics on the text as a whole. Along the way, they target academic vocabulary and specific sentence structures as critical focus points for gaining comprehension.
How many TDQ files are needed In CICS?
Each CICS region requires three files for TDQs: one holds logically recoverable TDQ data, one holds physically recoverable TDQ data, and one holds nonrecoverable TDQ data. These files are placed onto the file manager that is specified with the Region Definitions (RD) DefaultFileServer attribute when the file manager is set up.
What are the different types of queues in CICS?

What’s the difference between a TDQ and a TSQ?
TDQs are generally used for auto Transaction initiation process. While defining TDQs in DCT entry, TRIGGER level parameter exceeds Transaction coded in DFHDCT gets initialed automatically. – TDQs used to accumulate data before processing. – Read is destructive after a record read, it will be deleted.
