Heapdmp
This function generates a dump file of memory usage, for debugging purposes.
The dump file is created in the TRA subdirectory of the current folder. The function returns the path of the generated file.
This dump gives a detailed map of the instances allocated in each allocation group. It helps debug memory leaks.
Syntax
PATH=heapDmpExample of log file generated by this instruction
In this example, an instance of C_ATABLE (table description) was created in the [MYT] allocation group and an AREAD method was called on the key "ATABLE". The complete description of the table called ATABLE has been loaded and consists of the following:
- 1 instance of
C_ATABLEusing 3420 bytes (the header) - 35 instances of
C_ATABZONusing 37472 bytes (the description of the columns) - 2 instances of
C_ATABINDusing 1266 bytes (the description of the indexes) - 7 instances of
C_AMSKPARusing 2464 bytes (the parameters associated with some data types) - 667 instances of
C_ATXTSUPusing 206770 bytes (the translatable texts) - 304 instances of `C_ATTRIBUTE using 196688 bytes (the attributes of properties for all class properties) ``` ----------------------- OBJECTS MEMORY MAP ---------------------- Created by : DOM
