CICS COMMANDS – QUICK REFERNCE Some Useful System Commands: A brief introduction to CICS system tables and resources: In the CICS region, all the resources (like files, transactions, TDQs, programs etc.) are defined in system tables like (PCT, PPT, FCT, etc.). We cannot execute any transaction without the transaction being predefined in PCT and the associated program that the transaction initiates in PPT. Similarly we cannot use any files, which have not been defined in the FCT. Similar is the case for all the resources. Of course exception being resources like TSQs. But CICS gives the user very much flexibility in the sense that the resources that are defined to CICS are all logical. All the physical allocations are to be done by the user, which will cater to his needs and application requirements.

For example, the definition of a file to CICS is done in terms of its DDNAME. The user can allocate any physical file, which contains the data that cater to his application/testing needs as long as the properties of the file (like Key length, Key offset, Rec Size, etc) are consistent with those defined to the CICS in FCT. Similarly once a transaction and its associated program are defined to CICS, user can compile and create a load module of any program with the name defined and use the pre-defined transaction to execute the program. For example, in PCT and PPT the entries of transaction TRN1 and its associated program PGM1 are made. Now the user can compile some program XYZ with its name as PGM1 and use TRN1 to execute this program. But before we proceed further it is very important to note that for us to use/access any of the resources that have been defined to CICS, they have to be enabled.

And incase of resources like files, they have to be open. We have a Master Transaction CEMT to check the current status of a resource and also to change its current status as required by the user. Syntax: Type CEMT I and press enter. A lot of options will be shown to you.

Bpmn method and style bruce silver pdf free download. Out of these the options which will be of most concern to us are: FIle, PROGram, TRAnsaction. Now after I type the option you want along with the name of the resource you want to check. Note that it’s enough if we type the letters in capital case. Also we can directly inquire about a resource by directly typing the entire command CEMT I option (resource name) For example: CEMT I FI (ddname) is same as CEMT I FILE (ddname) Similarly, I PROG (program name); I TRA (transaction name) The logical name we specify can also be generic. Suppose if we type in CEMT I FI (*) and press enter, it will show us the status of all the files that are defined in the region.

Codes

If we want to limit our search then its better to give the entire resource name (if we know) or give a generic name by specifying the start of resource name followed ny an asterisks. Example: CEMT I FI (TM*) will display the status of all files whose DDNAME start with TM. But make sure to give ‘*’. If not it will search only for the file whose name is ‘TM’. Similarly we can inquire about PROG and TRA. Now let us see some examples: Example-1 FIle: CEMT I FI (FILENAME) Result: I FI(FILENAME) STATUS: RESULTS - OVERTYPE TO MODIFY Fil(FILENAME ) Vsa Clo Ena Rea Upd Add Bro Del Sha Dsn( PHYSICAL.FILENAME ) Vsa tells us that it is a VSAM file. (Not modifiable) Clo tells us that the file is Closed.

This can also be Ope meaning that the file is opened. Ena tells us that the file is Enabled. This can also be Dis meaning that the file is disabled. Rea tells us that we have access to read this file Upd tells us that we have access to update this file Add tells us that we have access to add new records to this file Bro tells us that we have access to browse through the file.
