What happens when you set the impex.legacy.mode property to True?Note: There are 2 correct answers to this question.
Answer(s): C,D
When you set the impex.legacy.mode property to True, you enable the legacy mode of ImpEx, which means that the ServiceLayer interceptors and validators are not triggered during the import/export process and that the INSERT, UPDATE, and REMOVE operations are not performed by the ModelService during the import. The legacy mode is a quick and crude way of importing data that bypasses the ServiceLayer of SAP Commerce. It may improve performance but also increase the risk of data inconsistency or errors.
Which actions do you perform to use the EDMX schema?Note: There are 3 correct answers to this question.
Answer(s): A,C,E
The actions that you perform to use the EDMX schema are using the <Association> ... </Association> tag as a representation of the relationship between entity types, defining the structure of the payload that the Integration API will support for both inbound and outbound requests, and using odata2webservices to get the EDMX schema for the integration object. The EDMX schema is an XML- based format that describes the data model of an OData service. It defines the entity types, properties, associations, and functions that are exposed by the service. You can use odata2webservices to generate the EDMX schema for an integration object based on its item types and attributes. You do not use ComplexType and EdmSimpleType as part of the <Association> ... </Association> tag, nor do you update the EDMX schema by downloading it, changing it, and re- uploading it within the SAP Commerce Backoffice.
What are the recommended tools to enable JDBC logs in SAP Commerce?Note: There are 3 correct answers to this question.
Answer(s): A,C,D
The recommended tools to enable JDBC logs in SAP Commerce are configuration properties file, Backoffice Administration Cockpit, and SAP Commerce Administration Console. You can use these tools to set various configuration parameters related to JDBC logging, such as jdbc.log.enable, jdbc.log.level, jdbc.log.file.path, or jdbc.log.trace. You can also use these tools to view or download the JDBC log files. You do not use ImpEx or Java code to enable JDBC logs in SAP Commerce.
SAP Commerce receives a Java OOM (out of memory) exception.What should you do first?Note: There are 2 correct answers to this question.
Answer(s): A,B
The steps that you should do first when SAP Commerce receives a Java OOM (out of memory) exception are analyzing the gc.log file for object allocation and taking a Java heap dump when the issue is detected. The gc.log file can help you monitor the garbage collection activity and identify any memory leaks or excessive object allocation. The Java heap dump can help you analyze the memory usage and distribution of objects in the heap. You should not analyze the access.log file for frequent requests or increase the memory size, as these steps may not address the root cause of the issue or may only delay its occurrence.
Which properties can you set to use Service Layer Direct?Note: There are 2 correct answers to this question.
Answer(s): B,D
The properties that you can set to use Service Layer Direct are setting the sld.enabled modifier to True in the ImpEx file and setting persistence.legacy.mode and servicelayer.prefetch to False in the local.properties. Service Layer Direct is a feature that allows the service layer to interact with the persistence layer more efficiently and use fewer resources. It can be enabled on an as-needed basis in your Java code or when invoking ImpEx. You do not set persistence.legacy.mode to False in core- spring.xml, as this is not a valid configuration file for this property.
