Open System Services Programmer's Guide

There are significant time and space trade-offs with compression:
• The none option is the fastest, but (the compressed dump) takes the most space.
• The gzip option is the next fastest, but takes up less space than none.
• The bzip2 option is the slowest, but takes up the least space.
In the absence of a save option, and in the saveabend case, compression is selectively applied
based on the uncompressed file size.
NOTE: Dumps can be compressed after the fact by using the standard utilities from the ITUG
Library.
eInspect Support
Beginning with the H06.24 and J06.13 RVUs, features of HP eInspect are:
• Re-based to GDB 6.8 from GDB 5.0
• Re-based to TCL 8.5 from TCL 8.0 and it supports 64-bit arithmetic
• Can be used to debug 64-bit processes
• Can be used to analyze both 32-bit and 64-bit snapshot files
eGarth Support
Beginning with the H06.24 and J06.13 RVUs, eGarth creates 64-bit snapshot files from a CPU
dump for processes having 64-bit segments.
Visual Inspect Support
Visual Inspect can be used to debug 32-bit processes with 64-bit segments; however, it does not
support live debugging of a 64-bit process. Also, Visual Inspect cannot be used to analyze the
new 64-bit format snapshot files that contain one or more 64-bit segments.
An attempt to debug a 64-bit process or open a 64-bit-capable snapshot file is rejected with an
error.
The Native Inspect debugger starts when specifying a 64-bit OSS program as the ossprog
parameter for either the run -debug or runv command, because Visual Inspect does not currently
support 64-bit programs.
