Reports
This chapter describes the AUDIT file (keyword) considerations and the interactive
XDP_REPORT macro.
6.1
AUDIT File Considerations
This section explains audit file creation and rollover behavior in XDP.
The AUDIT keyword determines the type and location of the XDP audit trails. You can
have multiple AUDIT entries for each type of audit trail.
There can be up to nine audit trails with XDP. Any or all of these nine available audit
trails can be defined as a standard NonStop file, a process name or IP address. The
AUDIT keywords described in Appendices
of these audit types.
6.1.1
Audit File Creation
Audit files are defined in the DPCONF file. If a filename is defined and does not exist,
XDP will create it with the following default parameters:
TYPE E
EXT(300,300,16)
REC 4000
BLOCK 4096
You can specify different EXTents in your DPCONF file as described in Appendix A3:
“
6.1.2
Diskfile Audit Trails
If a diskfile name is specified for the AUDIT and no diskfile exists, the file is created
with the default format of type E, rec 4000, block 4096, primary extent size 300 pages,
secondary extent size 300 pages and maxextents set to 16.
When audit file fills up, XDP will receive an error 45 when it attempts to write to it. At
that point, the current file will be renamed using the first three characters of the current
file’s name followed by a five digit sequence number. A new file will be created with the
original name and format and processing will continue. The numbered audit files will
continue to increment each time the audit file fills up and is rolled over.
