Read error

When a read error is detected in an area, the application program receives an AO status code.

An Error Queue Element (EQE) is created, but not written to the second CI nor sent to the sharing system in a data sharing environment. Application programs can continue to access that area; they are prevented only from accessing the CI in error. After read errors on four different CIs, the area data set (ADS) is stopped. The read errors must be consecutive; that is, if there is an intervening write error, the read EQE count is cleared. This read error processing only applies to a multiple area data set (MADS) environment.
