Multisystem Installations

If your MVS, VM, or VSE installation has multiple processors running under the same or different operating systems, it may be possible to combine all of your error records into one history file.

Use the steps shown in Table 1 to combine the error records.

Table 1. Combining Multisystem Error Records
STEP	ACTION
1	Unload the ERDS on each machine according to the appropriate method for that operating system. See History Files for information on creating a history file.
2	Choose one machine on which to run the EREP reports.
3	Transfer the history files from each of the other machines to the one chosen in step 2. Use the method of transfer provided by the operating system.
4	Combine the history files from all of the machines. Use the method of combining files provided by the operating system.
5	Run the EREP reports appropriate for your installation. Use the combined file as the history file.
Note: If you merge VSE with VM or MVS records into a single file, that input file must be defined as a standard label file.
