Resolving situation problems - corrective actions

You can resolve situation problems by either changing the formulation of situations
or rewriting the situation using the SCAN strcscan function. You can also use
non-UTF8 columns to rewrite the situation or combine predicates with an OR.
Procedure
Corrective actions
1. Change the formulation of any situations that are causing excessive processing.
2. For situations with wildcard * characters, perform one of the following steps:
v Rewrite the situation using the SCAN strcscan function instead of the
character-by-character pattern-matching function LIKE. For example,
situations with this simple LIKE"*/process" pattern can be rewritten as SCAN
"/process".
v Rewrite the situation using non-UTF8 columns. For example, *IF *LIKE
NT_System.User_Name_U *EQ '*group' can be rewritten as *IF *LIKE
NT_System.User_Name *EQ '*group' where User_Name is a non-UTF8 column
and User_Name_U is the corresponding UTF8 column.
v Rewrite the situation combining predicates with an OR. For example, *IF
*LIKE NT_System.User_Name_U *EQ 'group*' can be rewritten as *IF ( (
*VALUE NT_System.User_Name_U *EQ 'groupA' ) *OR ( *VALUE
NT_System.User_Name_U *EQ 'groupB' ) *OR ( *VALUE
NT_System.User_Name_U *EQ 'groupC' ) ).

Resolving firewall problems - diagnostic actions

A problem with firewall interference or a problem with communication between
the Tivoli Enterprise Monitoring Server and monitoring agents can be resolved by
using the ping command to verify the communication between the server and
agents.
Procedure
Diagnostic actions
1. Check connectivity between the monitoring agent and the monitoring server.
2. Use the ping command to verify whether communication exists between the
monitoring server and agents. Ping from the monitoring agent system to the
monitoring server, and then from the monitoring server system to the
monitoring agent.
v Use the IP address of the host name specified during agent configuration.
v If the communication is broken and you see high CPU, proceed to the
corrective actions.
3. Turn on the RAS1 trace log to verify whether the monitoring agent has made a
connection to the monitoring server. See "Setting traces" on page 43 for more
information.
