The CBROAMxx PARMLIB member contains one or more OAMXCF statements that allow you to use OAM in a Parallel Sysplex. The OAMXCF statement allows you to provide group and member names for OAMplexes and instances of OAM to be associated with various XCF groups and members to allow data sharing within the sysplex. There are also timeout values that are assigned to optical and tape request types to determine the number of seconds that OAM is to wait for completion of a read or write request that was shipped to another OAM within the OAMplex.
For more information on changing the OAMXCF values dynamically or defining the values when the CBROAMxx PARMLIB member is not used at initialization, see Using the UPDATE command to set OAMXCF values.
