Lock Governor (-LGovernor)

Use Lock Governor (-LGovernor) to specify the percentage of the lock table that a tenant can occupy in a multi-tenant database.

Operating system and syntax UNIX / Windows -LGovernor n
Use with Maximum value Minimum value Single-user default Multi-user default
Database Server 100 1 — 100
n

The percent of the lock table one tenant can occupy.

Note: Lock governor applies to the default tenant and a regular tenant. This governor does not apply to super-tenants and non multi-tenant databases.

Lock governor prevents a tenant from acquiring all the locks in a table. When a tenant attempts to acquire more locks than the governor allows, an error message is displayed and recorded in the database log as: 

Attempt to exceed tenant lock governor for tenant <tenantID>. Increase -L or -LGovernor.

You can set or modify the -LGovernor value using the PROMON utility. To set the -L value, see Lock Table Entries (-L); you can also modify the -L at runtime with PROUTIL INCREASETO. For more information about the PROMON and PROUTIL utilities, see Manage the OpenEdge Database.
