Server Activity Display - lock contentions
Use the Lock Contentions tab when a request is taking too long to process and you want to know why. The Lock Contentions tab displays any requests that are hanging because they are waiting on a lock. The data shows both the object that has the lock and the one that is waiting for a lock.
Open the Server Activity Display (lock contentions) page:
- From the top navigation,
Problem Determination | Server Activity Display
- Select a group and a server from the list box.
The active requests page opens. The information for the selected server group displays. If you have come to this page directly from the Tivoli Enterprise Portal, the group name and server name display automatically.
- Click Lock Contentions.
The Lock Contentions tab opens displaying the active locks. If no locks have occurred, the system message says, "There are no classes instrumented for lock analysis."
If there are any Active Locks (For active requests) the information displays under the following column headings:
- Locked Object Class
- Owners Request/Transaction Name
- Owners Request/Transaction Type
- Owner Class
- Owner Method
- Waiting Time (ms)
