What should an administrator do to resolve a Java heap space error in the vCenter Inventory Service?

Increase the memory resources of the vCenter Server.
Increase the values using cloudvm-ram-size.
Increase the memory resources of the Platform Services Controller.
Increase the wrapper.java.maxmemory value in wrapper.conf.

The correct answer is: Increase the memory resources of the vCenter Server.

To effectively resolve a Java heap space error in the vCenter Inventory Service, increasing the wrapper.java.maxmemory value in the wrapper.conf file is the most direct and relevant solution. This parameter specifically defines the maximum amount of memory that the Java Virtual Machine (JVM) can use. If the application exceeds this limit while processing data, it results in a Java heap space error. By increasing this value, you can allocate more memory for the Java processes, thereby mitigating the risk of encountering this error. While increasing the memory resources of the vCenter Server or the Platform Services Controller could potentially help overall performance, they do not specifically target the root cause of the Java heap space error in the Inventory Service. The same can be said for altering memory resources via cloudvm-ram-size; these adjustments may impact other operational aspects but won't directly resolve the heap space issue tied to the Java configuration in the Inventory Service. Therefore, modifying the wrapper.conf file is the most appropriate action to take in this scenario.
