Changing InnoDB Log Files in MySQL
To change the Number or Size of InnoDB redo log Files, follow these steps:
1 If innodb_fast_shutdown is 2, set it to 1:
mysql> SET GLOBAL innodb_fast_shutdown = 1;
2 After ensuring that innodb_fast_shutdown is not set to 2, stop the MySQL server and
make sure that it shuts down without errors (to ensure that there is no information for
outstanding transactions in the log).
3 Copy the old log files into a safe place in case something went wrong during the shutdown
and you need them to recover the tablespace.
4 Delete the old log files from the log file directory.
5 Edit my.cnf to change the log file configuration.
6 Start the MySQL server again. mysqld sees that no InnoDB log files exist at startup and
creates new ones.
SNMP in Multi-Homed Environment
Trap listener, Inform listener and all outbound SNMP requests must bind to a specific interface in
a multi-homed environment. This interface is considered appropriate to use for all network-facing
SNMP activity. By default, this is
localhost , interpreted as the application's local IP value (the
NIC selected at installation time). The following text in
installed.properties provides a
specific IP address to control outbound SNMP interface binding on the local machine:
# specific interface used for all NMS initated
# communications to the network
com.dorado.mediation.outbound.address=localhost
Include the following and provide a specific IP address to control inbound (listener) interface
binding on the local machine:
#
# specific interface used for binding mediation
# listeners such as SNMP trap listener
com.dorado.mediation.listener.address=localhost
Events with no corresponding definition appear as alarms of indeterminate severity. The only way
to change behavior of an unknown event in this version would be to locate the missing MIB and
load it into the system. This creates the missing event definition(s) needed to specify explicit
behaviors.
