The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• In the ALERTFILE text box, specify the path to the alert log files to be monitored. For eg, /user/john/alert_egurkha.log. 

• In the SEARCHPATTERN text box, enter the specific patterns of alerts to be monitored. The pattern should be in the following format:<PatternName>:<Pattern>, where <PatternName> is the pattern name that will be displayed in the monitor interface and <Pattern> is an expression of the form - *expr* or expr or *expr or expr*, etc. A leading '*' signifies any number of leading characters, while a trailing '*' signifies any number of trailing characters.

  For example, say you specify ORA:ORA-* in the SEARCHPATTERN text box. This indicates that "ORA" is the pattern name to be displayed in the monitor interface. "ORA-*" indicates that the test will monitor only those lines in the alert log which start with the term "ORA-". Similarly, if your pattern specification reads: offline:*offline, then it means that the pattern name is offline and that the test will monitor those lines in the alert log which end with the term offline.  

  Multiple search patterns can be specified as a comma-separated list. For example: ORA:ORA-*,offline:*offline*,online:*online

• In the LINES text box, specify two numbers in the format x:y. This means that when a line in the alert file matches a particular pattern, then x lines before the matched line and y lines after the matched line will be reported in the detail diagnosis output (in addition to the matched line). The default value here is 0:0. Multiple entries can be provided as a comma-separated list. 

  If you give 1:1 as the value for LINES, then this value will be applied to all the patterns specified in the SEARCHPATTERN field. If you give 0:0,1:1,2:1 as the value for LINES and if the corresponding value in the SEARCHPATTERN filed is like ORA:ORA-*,offline:*offline*,online:*online then:

0:0 will be applied to ORA:ORA-* pattern

1:1 will be applied to offline:*offline* pattern

2:1 will be applied to online:*online pattern

• In the INFO text box, specify the name of the Oracle instance being monitored.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
