Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
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 |
|
|
Either word in a topic |
|
|
Topics that do not contain a specific word or phrase |
|
|
Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
A combination of search types | ( ) parentheses |

Oracle RAC Topology by Shell Job
This section includes details about the job.
This job:
-
Connects to the remote host by Shell.
-
Checks for the ORACLE_HOME environment variable.
-
If it is not defined, the job uses the OracleHome value from the job adapter.
- Enumerates configured database service names using the command srvctl config database.
- Enumerates sids and hosts on which the service is available using the command srvctl status database –d <service_name>.
-
Retrieves RAC parameters such as Service Name and Nodes from the $ORACLE_HOME/network/admin/tnsnames.ora file.
-
Checks if this RAC instance is running, by parsing the lsnrctl status output.
Note Nodes are cited in the tnsnames.ora file by their internal IP or by their internal domain name. If the domain name appears, DFM resolves it.
-
Retrieves the full list of Listened IPs from the input query, for all listeners matching the query.
-
Parses this attribute's values from the list of listened IPs, to retrieve the Host Primary Domain name that corresponds to the MAC address. This is needed since the RAC CI's name key attribute must consist of a list of all the node domain names separated by the colon symbol (:).
-
Looks up the full node name in the build table sorted by IP address. The result is the Host Primary Domain name for each node.
At this stage, the following information is available: the RAC Service Name, the fully qualified domain names of all the RAC nodes, and a RAC instances count.
-
Creates the RAC CI.
Node Name | Condition |
---|---|
Node | None |
Oracle TNS Listener | NOT Listened IPs Is null |
Process | None |
IpAddress | NOT IP Probe Name Is null |
Shell | NOT Reference to the credentials dictionary entry Is null |
This job uses the Oracle_RAC_Topology_by_Shell adapter.
