WebLogic Server diagnoses a thread as stuck if it is continually working (not idle) for a set period of time. You can tune a server’s thread detection behavior by changing the length of time before a thread is diagnosed as stuck, and by changing the frequency which the server checks for stuck threads.
To configure thread detection behavior:
} } (document.images){ dcs_imgarray[dcs_ptr] = new Image; dcs_imgarray[dcs_ptr].src = dcs_src; WT[myMeta.name.substring(3)]=myMeta.content; } if DCSext[myMeta.name.substring(7)]=myMeta.content; } } } } for (N in DCS){P+=A( N, DCS[N]);} for (N in WT){P+=A( "WT."+N, WT[N]);} for (N in DCSext){P+=A( N, DCSext[N]);} //} aCrumb=aCookie[i].split("="); if (crumb==aCrumb[0]){ return aCrumb[1]; } } return null; } i=0;i
- If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
- In the left pane of the console, expand Environment > Servers.
- On the Summary of Servers page, select the server instance for which you will configure overload condition parameters.
- Select Configuration > Overload and update as needed:
- Shared Capacity For Work Managers - Total number of requests that can be present in the server.
- Failure Action - Specifies the action taken should a server instance detect a failed state.
- Panic Action - Specifies that action taken should a server instance detect a panic condition.
- Free Memory Percent High Threshold - Percentage free memory after which the server overload condition is cleared.
- Free Memory Percent Low Threshold - Percentage free memory below which the server is considered overloaded.
For more information about overload conditions, see Configuration Options.
- Click Save.
- To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
Not all changes take effect immediately—some require a restart (see Use the Change Center).
