Lock entry size parameter

The LOCK ENTRY SIZE parameter on installation panel DSNTIPJ determines the amount of space required for lock contention control information (that is, individual entries in the lock table).

The lock entry size and the number of lock table entries of the first IRLM to join the group determines the whole group's storage size for the lock table and the lock table entry width. The default is 2 bytes, which is probably the size you want, unless you immediately create a data sharing group of eight or more members. By restricting each lock entry to 2 bytes, you maximize the amount of RLE space available from the define structure size.
