The encyclopedia concurrency matrix is the table of rules that determine which functions are compatible to run at the same time. An enqueue wait occurs when a second process is started that violates the rules of the concurrency matrix. The second process is put into wait mode and retried every minute to see if the enqueue still exist. After a specified number of retries per function, the second process terminates (it never really got started) with a resource conflict message. An enqueue wait occurs only at the model and subset level (there is no encyclopedia-wide enqueue contention).
Some of the more common restrictions are:
Encyclopedia users should be aware of the concurrency matrix and know how to use it.
Note: For more information, see CA Gen Host Encyclopedia Subsetting User Guide.
Note that the matrix shows only the concurrency enforced by the Host Encyclopedia. Other types of contention, such as that caused by DB2, cannot be determined from the matrix.
