NUMBER OF LOCK ENTRIES field
The value of the NUMBER OF LOCK ENTRIES field specifies the number of lock table entries that are to be in the coupling facility lock structure.
| Acceptable values: | 0, 1–2048 (powers of two) |

| DSNZPxxx: | none |
- 0
- Specifies that IRLM determines the number of lock table entries, up to a maximum of 2048 M lock entries, based on the lock structure size that is specified in CFRM policy and the number of users (MAXUSRS). 0 is the default value.
- value (1–2048)
- Specifies that the maximum number of lock table entries is value M (the value that you specify multiplied by 1,048,576). value must be a power of two. (Do not specify M in value.) Increasing the number of lock table entries might help reduce the amount of false contention in XES. However, allocating too many lock table entries might result in too few record list entries. You should monitor this number to find the optimum values for your installation.
The associated IRLM PROC parameter is LTE.
