Ranking List

For each entry, the following information is displayed:

      Ranking

The system ranks memory objects by memory consumption.

      Bound (Allocated)and Bound (Used) Memory

Bound memory is freed up when a complete deletion takes place (for internal tables, with FREE). The bound memory of an object also includes the memory used by objects that only exist as references to that object. For example, if an internal table exclusively contains references to data objects that can be released by the garbage collector after the table is deleted, the referenced objects also contribute to the bound memory.

      Referenced (Allocated)and Referenced (Used) Memory

This is the memory referenced by the data object (possibly skipping other data objects). This memory is not released when the data object is deleted, if other data objects still reference that memory. The referenced memory is always larger than or equal to the bound memory.

      SCC (Allocated) and SCC (Used) Memory

A strongly connected component has the property that for every two elements, A and B of such a component, there is a path in the object graph from A to B and from B to A. Therefore, the elements of a strongly connected component can be deleted only by the garbage collector, provided all outside references to elements of the component were deleted. Strongly connected components can be viewed as composite objects that can only be deleted as a whole.

Ranking List by Type

In addition to the Ranking List, the Ranking List by Type, has the Lines / Instances column, which contains the number of lines of tables or the number of class instances, respectively.

Tables

For each table, the following information is displayed:

      Lines (Allocated), Lines (Used), and UsedLines (%)

The columns display the allocated and used lines, as well as the percentage of usage.

      Bound (Allocated)and Bound (Used) Memory

      Referenced (Allocated)and Referenced (Used) Memory

      Column Width

      RefCount

The column contains the number of references to the table.

Classes

For each class, the following information is displayed:

      Ranking

      Number of Instances

      Bound (Allocated)and Bound (Used) Memory

      Referenced (Allocated)and Referenced (Used) Memory

      Class Attributes

      Instance Size

Programs

For each program, the following information is displayed:

      Ranking

      Global Data

      Number of Instances

      Number of Tables

      Number of Strings

      Number of Data Objects

System Memory

For each service, the following information is displayed:

      Ranking

      Size

The memory consumption of the service

Memory Management

For each parameter, the following information is displayed:

      Ranking

      Total Size

      Number

The number of parameters.

Object Cycles (SCC)

For each object cycle, the following information is displayed:

      Ranking

      Number of Memory Objects

The number of objects in each cycle.

      Bound (Allocated)and Bound (Used) Memory

      Referenced (Allocated)and Referenced (Used) Memory
