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 |

How to Discover Full SAP Java-related Topology
The SAP Java Discovery enables you to discover the full SAP Java-related topology and J2EE applications on the SAP JAVA server.
The jobs that you need to run to perform this discovery are determined by whether shell access is provided to SAP destinations. If shell access is provided, then perform discovery as described in SAP Java Discovery with Shell Access Provided to SAP Destinations. If shell access is not provided to SAP destinations, perform discovery as described in SAP Java Discovery without Shell Access Provided to SAP Destinations.
The following diagram depicts the various scenarios for running SAP Java Discovery.
Note When shell access is provided to SAP destinations, SAP Java Discovery can be performed either in shallow mode or in deep mode. To perform a shallow discovery, carry out steps 1-3 below. To perform a deep discovery, carry out all of the steps below.
To perform the SAP Java Discovery:
- In the Universal Discovery window, run the Range IPs by ICMP job. This job discovers all reachable IPs.
-
Run the Host Connection by Shell job. This job discovers the host's connectivity by shell protocol to application servers.
-
Run the Host Applications by Shell job. This job discovers application servers, message and enqueue servers, and their relationships to the SAP system.
Note If you want to perform only a shallow discovery, stop here and do not continue to the next step.
-
Run one or more of the following jobs (depending on the type of Java topology you want to discover):
-
SAP Java Topology by HTTP. This job discovers the full SAP Java topology, including databases used. It determines system configuration, which is either standalone Java or Double Stack.
-
SAP Java Topology by SAP JMX. This job discovers the full SAP Java topology with details about instances. Databases are discovered only when the new MBean model is available (starting from Java application server version 7.1). It is not possible to determine the type of system configuration.
-
SAP Java Topology by WebServices. This job is the same as the JMX job, but with a different transport.
-
To perform the SAP Java Discovery:
- In the Universal Discovery window, run the Range IPs by ICMP job. This job discovers all reachable IPs.
- Run the SAP TCP Ports job.

Run one or more of the following jobs (depending on the type of Java topology you want to discover):
