Appearance of aggregated messages

The following examples illustrate how MVS™ aggregates command responses. In these examples, the command responses are returned to an out-of-line area on the console. The sysplex has three systems, named SYS1, SYS2, and SYS3.

Example 1: Comparison of Aggregated and non-Aggregated Messages: The following two panels use the D T command (DISPLAY TIME) to show how command responses are aggregated.

The following panel shows several uses of the D T command without aggregation of command responses: 
     - SYS1  d t

     - SYS1  ro sys2,d t

 A 
The D T command is issued and processed on SYS1.
 B 
The D T command is issued on SYS1 and routed to SYS2 for processing.
 C 
The D T command is issued on SYS1 and routed to all systems (SYS1, SYS2, and SYS3) for processing. To ensure that responses are not aggregated, T=0 is specified.
The following panel shows the difference between non-aggregated and aggregated command responses:

 A 
The D T command is issued on SYS1 and routed to all systems (SYS1, SYS2, and SYS3) for processing. With T=0 specified on the ROUTE command, responses to D T from the three systems are not aggregated.
 B 
Again, the D T command is issued on SYS1 and routed to all systems (SYS1, SYS2, and SYS3) for processing. With T=5 specified on the ROUTE command, responses to D T from the three systems are aggregated. In this example, the aggregated messages are shown in highlighted text. Note how the responses in the T=5 response are formatted as compared to the T=0 response.
Example 2: Another Sample Aggregation of Command Responses: The following two panels use a very short timeout interval (T=1) to show how non-aggregated responses are handled. 
     A 
  - SYS1  ro t=1,*all,v 414,offline





  B 
 IEE421I RO *ALL,V 414,OFFLINE        FRAME  1     F      E   SYS=SYS1
 NO RESPONSE RECEIVED FROM THE FOLLOWING SYSTEM(S):
 SYS2







IEE612I CN=C3E0SS1  DEVNUM=03E0 SYS=SYS1     CMDSYS=SYS1


IEE163I MODE= RD
 A 
The ROUTE command is used to try to vary device 414 offline on all systems. A timeout interval of 1 second (T=1) is specified on the ROUTE command.

System SYS2 does not respond within one second. Therefore MVS cannot include the command response from SYS2 in the aggregated response.

 B 
MVS lists the systems from which no response was received in time for aggregation. In this case, only SYS2 is listed, under NO RESPONSE RECEIVED FROM THE FOLLOWING SYSTEM(S):. This output is in FRAME 1 of message IEE421I.
   - SYS1  ro t=1,*all,v 414,offline
   C 
   - SYS2   IEF281I 0414 NOW OFFLINE







  D 
 IEE421I RO *ALL,V 414,OFFLINE        FRAME LAST   F      E   SYS=SYS1
 SYSNAME  RESPONSES ---------------------------------------------------

IEE612I CN=C3E0SS1  DEVNUM=03E0 SYS=SYS1     CMDSYS=SYS1


IEE163I MODE= RD
 C 
MVS displays the non-aggregated command response from SYS2. The time when the non-aggregated messages appear does not depend on when the operator scrolls to the second frame of message IEE421I.
 D 
After the operator scrolls forward to the second (and last) frame of message IEE421I, MVS displays the aggregated messages.
