Before you perform an encyclopedia function that may cause contention, see which functions are currently running. You can use several methods to determine what is running. (The methods vary greatly from site to site.) One method is to check DB2 threads; another is to use a performance monitor.
To match the plans with the encyclopedia functions, you need to know the plan suffixes and the plan prefix used for that encyclopedia. See the Encyclopedia Function Plans appendix for a list of all the function plans and a description of each plan. You will probably encounter the following plan suffixes as you work on improving encyclopedia performance:
After you identify what is currently running, use the concurrency matrix to determine if the function you want to run is allowed at the same time.
Note: For more information, see Encyclopedia Concurrency Matrix in CA Gen Host Encyclopedia Subsetting User Guide.
Since the concurrency matrix deals with activity in the same model, you need to know what model the active function is running against. This is not always easy to find out. You have at least two ways to deal with this:
