The remaining environment details are in the following sections:

RAC instance connection details

In the RAC instance connection details section, click Add. The RAC instance connection details pane is displayed.

Field	Description
Oracle SCAN	Enter the hostname or the IP address used for the Oracle RAC. You can use the $HOSTNAME variable for the Oracle host. The name is taken from the PATROL agent that is registered in the TrueSight console's Devices page. The IP address can be in the IPv4 or IPv6 format. An example of an IPv6 address is [2001:db8:28:3:f98a:5b31:67b7:67ef].
Oracle SCAN listener port	Enter the port number that is used to connect with the Oracle RAC Database. The default port number is 1521.
Oracle RAC service name	Enter the RAC service that you want to monitor. To get a list of RAC services, use the srvctl command.
Connect as SYSDBA	Select this option to connect to the Oracle RAC instance as SYSDBA privileged user. Note: We do not recommend monitoring using a user with SYSDBA privileges.
Oracle credentials
User Name	Enter the user name to connect to the Oracle RAC Database. Note: Confirm that you have permission for object access, see Monitoring-categories-and-user-permissions.
Password Confirm password	Enter the password to connect to the Oracle RAC Database. Confirm the password. If you are using vault to access the password in BMC Helix Operations Management, enter the query string in the Password and Confirm password field.
Oracle Custom SQL Queries
Query name	In the Oracle Custom SQL Queries section, click Add. On the Custom SQL Query pane, enter the name for the SQL query. Note The name cannot include blank spaces or any of the following special characters: # $ \ ' \| ~ ! @ % ^ ; ` ( ) { } ? \ " [ ] + = & : > < * / After you save the environment configuration, you cannot change the name without losing the environment's historical data. You can change the environment name by making a copy of the monitoring solution and then changing the environment name.
SQL query	Enter the SQL query command. Note The SQL query must not contain the semicolon (;).
Collection time (min)	Enter the SQL query collection time. The default collection time is 10 minutes.
Enable number of records annotation	Select this option to display the query result as an annotation on number of records metric.

Monitoring Categories details

Select the Oracle RAC Database activity categories and tablespaces that you want to monitor.

The Node availability monitor category is discovered by default.

Monitoring Categories	Description
ASM	Monitors the performance of the Oracle Database ASM disks. For more information, see the ASM-Disk-KOE_INST_ASM_DISK monitoring category.
Fast Recovery Area	Monitors the performance of the Oracle Fast Recovery Area disks. For more information, see the Oracle-Fast-Recovery-Area-KOE_INST_FRA monitoring category.
Operating System usage	Monitors the operating system utilization statistics and system resources. For more information, see the Oracle-OS-Usage-KOE_INST_OS monitoring category.
Pluggable Database	Monitors the pluggable databases. If the Oracle Database is not a pluggable type, this monitoring category is not created for this monitoring policy. For all RAC instances, information about pluggable tablespaces is shown globally outside the hierarchy of pluggable databases. For more information, see the Pluggable-Database-KOE_INST_PLUGGABLE_INSTANCE monitoring category.
Services	Monitors the Oracle services executed inside the Database. For more information, see the Services-KOE_INST_SERVICE monitoring category.
Sessions	Monitors the sessions activity of the Oracle Database. For more information, see the Sessions-KOE_INST_SESSIONS monitoring category.
Wait Events	Monitors the wait events in the Oracle RAC Database. For more information, see the Event-Class-KOE_INST_EVENT_CLASS monitoring category.
Tablespaces
Tablespaces	Select this option to monitor the tablespaces. To monitor large and very large tablespaces under separate application classes (Oracle-Large-Tablespace-KOE_INST_LARGE_TABLESPACE and Oracle-Very-Large-Tablespace-KOE_INST_VERY_LARGE_TABLESPACE), configure the minimum size (in MB) of the large and very large tablespaces in the following configuration variables (both are required). Set configuration variables in the Configuration Variables on the Add Configuration Variable page. /KOE/Oracle/<EnvType>/<EnvName>/LargeTablespaceSize /KOE/Oracle/<EnvType>/<EnvName>/VeryLargeTablespaceSize Replace EnvType with DataGuard, Standalone, or RAC and <EnvName> with the name you used in the Environment name field. Restart the PATROL Agent after configuring these configuration variables. If you do not configure values in one or any of these variables or if the value in VeryLargeTablespaceSize is smaller than the value in LargeTablespaceSize, all tablespaces are discovered under the Oracle-Tablespace-KOE_INST_TABLESPACE class. For example, you configure the value of the LargeTablespaceSize variable as 200 and the value of the VeryLargeTablespaceSize variable as 500. The tablespaces between the sizes 200 and 500 MB are monitored under the Oracle-Large-Tablespace-KOE_INST_LARGE_TABLESPACE application class, and the tablespaces with sizes more than 500 MB are monitored under the Oracle-Very-Large-Tablespace-KOE_INST_VERY_LARGE_TABLESPACE application class. Important: These configuration variables do not apply to UNDO and TEMP tablespaces.
Tablespaces filtering options
Filtering mode	Select the filtering mode: None Include Exclude
Include/Exclude matching criteria	Based on the selection of the filtering mode, specify the tablespaces to include or exclude from monitoring. Use comma (,) only to separate the tablespaces. For example, consider the tablespace name as DB12. For this tablespace, you can use any of the following methods to include or exclude tablespaces from monitoring: Starts with: ^DB.* Contains: .B1. Ends with: .12$ Equals to: DB12 Note* Be cautious when you add spaces while entering the regex search string. Extra space is considered as a character by the search string.
Filter for top n queries by total wait time For more information, see Monitoring-of-wait-time-attributes-of-SQL-query.
Total wait time monitoring	Select this option to enable the filter for top n queries by total wait time.
Top Number of queries	Enter the number of queries that you want to filter. This is a mandatory field. The valid input range is 1-100.
Maximun query instances limit	Enter the maximum number of query instances to filter. This is a mandatory field. The valid input range is 1-2500.
Number of days to keep query instances	Enter the number of days to keep the query instance. This is a mandatory field. The valid input range is 1-60.

Environment Settings details

Field	Description
Logging	Select this option to enable detail-level logging for all PostgreSQL databases configured on this environment to get more details about policy configuration and data collection. The log files are created under the PATROL_HOME directory: Java: PATROL_HOME/Patrol3/koekm/logs/java PSL: PATROL_HOME/Patrol3/log/koe-*.kmlog For more information about logging, see Using-debug-logging-in-the-TrueSight-Infrastructure-Management-operator-console.
Device mapping	By default, device mapping on the TrueSight console is enabled. If enabled, all the Oracle RAC Database instances are discovered under the Oracle host device. If it is disabled, all the Oracle RAC Database instances are discovered under the PATROL Agent host device.
Java collector settings
Java path	Enter the path to the JRE directory (also known as $JAVA_HOME environment variable) on the PATROL Agent host. If you use the $JAVA_HOME variable, the Java location depends on the following: No username and password are entered for the Java collector settings; the KM uses the Java location of the user running the PATROL Agent. A username and password are entered for the Java collector settings; the KM uses Java location of the user entered in the collector settings. If you enter a path for the JRE directory, you must enter the full path, such as C:\Program files\Java\jre1.8.0_151. Do not use the short path format. If you do not enter a value in this field, the KM looks for the Java installed in the PATROL Agent home directory as: Linux: $PATROL_HOME/../openjdk; $PATROL_HOME/../jre64 Windows: %PATROL_HOME%/../openjdk; %PATROL_HOME%/../jre64
JVM arguments	Enter the optional Java Virtual Machine (JVM) arguments for the Java collector.
User name	Enter the local user name to start the Java process.
Password Confirm password	Enter the password to start the Java process. Confirm the password.
Collection settings
Availability collection interval (min)	Enter the time interval used to check for the availability of environment for collecting data. The default interval is one minute.
Data collection interval (min)	Enter the time interval used for data collection from the environment. The default interval is five minutes. Note: If data collection time is set to less than 5 minutes, there might be KM performance issues.
Long running data collection queries (min)	Enter the time interval used to determine when a running query is blocked. The query is blocked because its execution duration is equal to, or greater than, this interval's threshold. The default interval is 30 minutes.
Wait time sql data collection interval (min)	Enter the total time interval in minutes to collect or report the value for the wait time SQL attributes. This attribute is valid for SQL instances attributes only. The default wait time SQL data collection time is 5 minutes. The valid input range is 5-60. For more information, see Monitoring-of-wait-time-attributes-of-SQL-query.
