LEAF_NODE_READ_LOCK

LEAF_NODE_READ_LOCK YES | NO

Default: YES

When enabled, FairCom DB Server acquires a read lock on a leaf node if the index does not use key compression. If it finds that the node contains transaction marks, it releases the read lock and acquires a write lock on the node. This greatly improves scalability of leaf nodes reads.

This option is dynamically configurable at runtime using the ctadmn utility's option (menu option 10, and then menu option 10, Change the specified configuration option, again) to change a server configuration option value.
