How To Safely Delete SQL Server ErrorLog Files

How To Safely Delete SQL Server ErrorLog Files


By default SQL Server stores seven ErrorLog files named:
  • ErrorLog
  • ErrorLog.1
  • ErrorLog.2
  • ErrorLog.3
  • ErrorLog.4
  • ErrorLog.5
  • ErrorLog.6
n SQL Server 2005 and later versions, the ErrorLog files are stored in the c:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG folder.  The ErrorLog file contains the newest information; the ErrorLog.6 file contains the oldest information. 

If one of the ErrorLog files has grown to a large size, the ErrorLog files can be manually cycled by running the sp_cycle_errorlog Stored Procedure.  

Delete 
  • ErrorLog manually

In SQL Server Management Studio, open the MANAGEMENT folder, then right click on SQL SERVER LOGS and say CONFIGURE.  Check the LIMIT ERROR LOGS box and set the number to 30 (a month's worth).  Now, set up a new job in the SQL Agent that runs sp_cycle_errorlog every night at midnight.

cisco 1242 dtim wmm

Choosing “Mixed 802.11g, 802.11b and 802.11n” and using WMM function are forbidden
for wireless mode.



When client devices receive a beacon that contains a DTIM, they normally wake up to check for pending packets. Longer intervals between DTIMs let clients sleep longer and preserve power. Conversely, shorter DTIM periods reduce the delay in receiving packets but use more battery power because clients wake up more often.

The default beacon rate is 2, which means that every other beacon contains a DTIM. Enter a beacon rate between 1 and 100.


WMM is in QoS , 


QoS is disabled by default (however, the radio interface always honors tagged 802.1P packets even when you have not configured a QoS policy). This section describes how to configure QoS on your access point. It contains this configuration information:
