2.4 Monitoring Tuxedo Targets

Before monitoring Tuxedo targets from Enterprise Manager Cloud Control, note the following:

• Make sure the Enterprise Manager OMS, Enterprise Manager Agent, and the DB instance time zones are the same. Take the following SQL script as an example to select SQL and modify the DB instance time zone: SQL> select dbtimezone from dual;

  SQL> select dbtimezone from dual;
  SQL> select sessiontimezone from dual;
  SQL> alter database set time_zone='<new time zone>';
  SQL> alter session set time_zone='<new time zone>';

• If you change the collection interval, make sure:
  • the collection interval for the SERVICE_STATISTICS metric of all targets in a domain are the same;
  • the collection interval for the CLIENT_CONNECTION_NUMBER metric of domain and machine targets in a domain are the same;
  • the collection interval for the domain metric DOMAIN_OPERATION_STATISTICS is same to the one of machine metric MACHINE_OPERATION_STATISTICS within the domain.
• You can easily change the collection interval for a batch of targets by clicking Enterprise->Monitoring->Monitoring Templates to create a template and applying it to multiple targets.
• A 5 or 15 minutes target collection interval is highly recommended.

  The following table summarizes the Tuxedo targets you can monitor from Enterprise Manager Cloud Control and the references to the metrics each target supports and specific administrative operations you can perform on each target home page.

Note:

• When you change the collection interval of a Enterprise Manager console target, it takes effect on metrics data collection from the next interval.
• All metrics with repository-side type only process historical database context and cannot be viewed in real time; otherwise, an exception of NoSuchMetricException is printed in oms log ($MW_HOME/gc_inst/em/EMGC_OMS1/sysman/log/emoms.log).
