Which record would be retrieved in VSAM RRDS if RRN has 95 when executing the below command, assuming record has 1000 records in a file?

EXEC CICS READDATASET(MYDATASET)INTO (MY-DATA-AREA)RRN(95)END EXEC

ans---

lets assume it as a fixed length record, so it retrieves 95th record

VSAM relative file organization(Also referred to as VSAM fixed-length or variable-length RRDS (relative-recorddata set) organization.) A VSAM relative-record data set (RRDS) contains recordsordered by their relative key. The relative key is the relative record number that represents the location of the record relative to where the file begins. Therelative record number identifies the fixed- or variable-length record.In a VSAM fixed-length RRDS, records are placed in a series of fixed-length slots in storage. Each slot is associated with a relative record number. For example, in a fixed-length RRDS containing 10 slots, the first slot has a relative record number of 1, and the tenth slot has a relative record number of 10.

In a VSAM variable-length RRDS, the records are ordered according to their relative record number. Records are stored and retrieved according to the relative record number that you set.

Throughout this documentation, the term VSAM relative-record data set (or RRDS)is used to mean both relative-record data sets with fixed-length records and with variable-length records, unless they need to be differentiated.

If you want to define fixed length records, which one of the following parameter

s in the FCT do you code?Choice 1The LENGTH parameter

Choice 2The STRNO parameter

Choice 3The RECFORM parameter

Choice 4The BASE parameter

Choice 5The FIXED parameter

The 3270 bridge provides an interface so that you can run 3270-based CICS® transactions without a 3270 terminal.

The 3270 terminal and end-user are replaced by an application program, known asthe client application. Commands for the 3270 terminal in the CICS 3270 user transaction are intercepted by CICS and replaced by a messaging mechanism that provides a bridge between the client application and the CICS user transaction.CICS provides two types of 3270 bridge mechanism:

The Link3270 mechanismThis mechanism is introduced in CICS Transaction Server for z/OS®, Version 2 R

elease 2 and provides a simplified interface using LINK, ECI or EXCI. All messages have a fixed format and you are not required to provide any user-written supporting programs. This mechanism supports CICSPlex® SM load balancing; bridge facilities are shared between CICS regions on the CICSplex.The START BREXIT mechanism

This 3270 bridge mechanism requires a bridge monitor transaction to initiatethe bridge environment by issuing a START BREXIT command, which specifies the target user transaction and also the name of a user-written bridge exit. The bridge exit is called to intercept 3270 requests and pass them in the form of messages to the client application. You can write your own bridge exit and also defineyour own message formats. Bridge exits are provided to support client applications using Temporary Storage, the Web and WebSphere® MQ as transport mechanisms forrequests, using sample message formats. This mechanism is single region only: bridge facilities are local to the region.

MAPFAIL

occurs if the data to be mapped has a length of zero or does not contain a set-buffer-address (SBA) sequence. It applies only to 3270 devices. The receiving data area contains the unmapped input data stream. The amount of unmapped data moved to the user's area is limited to the length specified in the LENGTH option. Th

e input map is not set to nulls. This condition also arises if a program issuesa RECEIVE MAP command to which the terminal operator responds by pressing a CLEAR or PA key, or by pressing ENTER or a PF key without entering data. Default action: terminate the task abnormally.

Normally MAPFAIL just indicates that no data has ben entered in any of the fields, and thus the MDT-bit is not set in the fileds attribute-byte. CICS issues a"Read Modified" 3270-command, and receives data from fields that has the MDT-bitset. When you get MAPFAIL, this just tells you that no field has been modified,an really is "normal".In program logic you have to check if data has been entered in mandatory fileds.The result may vary, and is a result of users action. Zero or many fileds may h

ave been modified.In your program logic you should FIRST check for invalid PF/PA/Clear-keys, and ONLY do a Receive Map after the check. There is no need to do a Receive Map if the user pressed the Clear or a PA-key, as an example. The EIBAID contains the value for the key pressed to initiate this pseudoconversation - even without a Receive Map.If you use Resp Option, coding RESP(ws-variable) in your Receive Map, you can eliminate the Mapfail problem. If you have an "old-style" program using Handle Condition, there is more to say, and recommendation is to just go away from this styel/model.
