Troubleshooting and Limitations – Oracle Database Server Discovery

This section describes troubleshooting and limitations for Oracle Database Server discovery.

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

If you need to discover Oracle 8g, use the following values in jdbcDrivers and jdbcPreUrls:

jdbcDrivers:

<oracle>com.inet.ora.OraDriver</oracle>
<oracleSSL>com.mercury.jdbc.oracle.OracleDriver</oracleSSL>

jdbcPreUrls:

<oracle>jdbc:inetora:%%ipaddress%%:%%protocol_port%%:%%sqlprotocol_dbsid%%?logging=false&amp;loginTimeout=%%protocol_timeout%%</oracle>
<oracleSSL>jdbc:mercury:oracle://%%ipaddress%%:%%protocol_port%%;ServiceName=%%sqlprotocol_dbsid%%</oracleSSL>

Oracle Data Guard Discovery cannot distinguish the logic standby instance or physical standby instance. SQL query cannot fetch such information if standby databases cannot be connected by SQL*Plus.

Oracle account will be locked if Data Flow Probe tries to log in to Oracle with SQL*Plus many times but fails. This depends on the Oracle configuration.
