Dynamic patch space allocation means that TotalView dynamically allocates patch space for code fragments. If you do not specify the size and location for this space, TotalView allocates 1 MB. TotalView creates this space using system calls.
TotalView allocates memory for read, write, and execute access in the addresses shown in the following table:
Platform
Address Range
IBM AIX (-q32)
0xEFF00000 - 0xEFFFFFFF
IBM AIX (-q64)
0x07f0000000000000 - 0x07ffffffffffffff
NOTE >> You can allocate dynamic patch space only for the computers listed in this table.
If the default address range conflicts with your program, or you would like to change the size of the dynamically allocated patch space, you can change the following:
• Patch space base address by using the -patch_area_base command-line option.
• Patch space length by using the -patch_area_length command-line option.
