What issues arise in instrumenting a Java application using IBM SDK Java when the
command line to start the application is not readily accessible? (Select 2)

A. Some code compilation or modification is needed.

B. You can set the IBM_JAVA_OPTIONS environment variable to add the argument into the application startup.

C. IBM SDK Java is not supported.

D. Setting the IBM_JAVA_OPTIONS environment variable will add the same argument into every IBM SDK Java application startup.

Question #2 - Topic 1

Which statement is incorrect about how dynamic sampling agents (DSAs) manage 1-
second data storage?

A. By default, the DSA attempts to keep 1-second data for 2 hours. The length of this time period is specified by the RawDataPersistDuration attribute in the dsa.xml file.

B. The DSA deletes the oldest 1-second data from the database If there is less than 10 percent of free disk space (the default for the RawDataPersistFreeSpaceTargetPercent attribute)

C. The DSA deletes the oldest 1-second data from the database if the database file is larger than specified in the RawDataPersistMaxDiskTarget attribute (unlimited as default).

D. If both the RawDataPersistFreeSpaceTargetPercent and RawDataPersistMaxDiskTarget attributes are satisfied, the DSA deletes data, if necessary, to retain only as much data as specified by RawDataPersistDuration.

E. At startup, and every 2 hours thereafter (or the frequency specified by RawDataPersistPurgeInterval), the DSA deletes the oldest 1-second data from the database.

A. You can toggle back and forth between the source code and the AppInternals Xpert performance data to examine selected class/method transactions that exceed a particular duration.

B. You can open the source code directly into Transaction Trace Warehouse.

C. In Visual Studio or Eclipse source code, you can click on the name of a generic method or click inside the code for the method and link to traces on transactions that the .NET or Java code generated, and display those transactions in Transaction Trace Warehouse.
