Flag Description -k ErrorID[,ErrorID] Deletes all error log entries except those specified by the ErrorID (error identifier) variable. The ErrorID variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -K ErrorLabel Deletes all error log entries except those specified by the ErrorLabel variable. The ErrorLabel variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -l SequenceNumber Deletes error log entries with the specified sequence numbers. The SequenceNumber variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -m Machine Deletes error log entries for the machine specified by the machine variable. The uname -m command returns the value of the machine variable. -n Node Deletes error log entries for the node specified by the node variable. The uname -n command returns the value of the node variable. -N List Deletes error log entries for the resource names specified by the list variable. For hardware errors, the list variable is a device name. For software errors, the list variable is the name of the unsuccessful executable. The list variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -R List Deletes error log entries for the resource types specified by the list variable. For hardware errors, the list variable is a device type. For software errors, the value of the list variable is LPP. The list variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -S List Deletes error log entries for the resource classes specified by the list variable. For hardware errors, the list variable is a device class. The list variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. -T List Deletes error log entries for error types specified by the list variable. Valid list variable values are: PERM, TEMP, PERF, PEND, INFO, and UNKN. The list variable values can be separated by commas, or enclosed in double quotation marks and separated by commas or space characters. 126 IBM ^ Certification Study Guide - AIX 5L Problem Determination Tools and Techniques
To delete all entries from the error log, enter: # errclear 0 To delete all entries in the error log classified as software errors, enter: # errclear -d S 0 6.5 Accounting Flag Description -y FileName Uses the error record template file specified by the FileName variable. To clear all entries from the alternate error log file /var/adm/ras/errlog.alternate, enter: # errclear -i /var/adm/ras/myerrlog 0 To clear all hardware entries from the alternate error log file /var/adm/ras/errlog.alternate, enter: # errclear -i /var/adm/ras/myerrlog -d H 0 Note: Once the errclear command has been run, it clears the error log, and this data is no longer available. To get this error information, the error log would have to be restored from a backup prior to running the errclear command. The accounting system allows you to collect and report on individual, group, and Workload Manager (WLM) class use of various system resources. This accounting information can be used to bill users for the system resources they utilize, and to monitor selected aspects of the system operation. To assist with billing, the accounting system provides the resource-usage totals defined by members of the adm group, and, if the chargefee command is included, factors in the billing fee. The fileset bos.acct contains the accounting commands and configuration files. The accounting system also provides data to assess the adequacy of current resource assignments, set resource limits and quotas, forecast future needs, and order supplies for printers and other devices.
