Measures reported by OraRacSesModuleTest

In the database context, the connection between the user process and the server process is called a session. The server process communicates with the connected user process and performs tasks on behalf of the users.

This test reports the numerical statistics of the wait events pertaining to all the session modules of this Oracle instance.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Cpu_waits Indicates the total number of CPU waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number A high value indicates performance degradation of the Oracle server.
User_IO_waits Indicates the total number of I/O waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number A high value indicates performance degradation of the Oracle server.
Cluster_waits Indicates the total number of waits pertaining to cluster resources that have occurred in all session modules of this Oracle instance since the last measurement period. Number A high value indicates performance degradation of the Oracle server.
Commited_waits Indicates the total number of Commit waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number If this measure shows a high value, refer to the detailed diagnosis capability of this measure which will show all the sessions that are affected by commited waits.
Transaction_lock_waits Indicates the total number of transaction lock waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number If this measure shows a high value, refer to the detailed diagnosis capability of this measure which will show all the sessions that are affected by the Lock waits.
Latch_waits Indicates the total number of Latch waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number A high value indicates performance degradation of the Oracle server.
Other_waits Indicates the total number of miscellaneous waits that have occurred in all session modules of this Oracle instance since the last measurement period. Number A high value indicates performance degradation of the Oracle server.
