6.15.1 Generating summary diff report

Using the PDB comparison option along with the -summaryoption displays the difference between the summary reports of 2 PDBs. The following example shows the usage of -basepdb <basepdbname> summary difference report:

6.15.2 Generating detailed diff report

Using the PDB comparison option along with the -alloption displays the detailed difference between the reports of 2 PDBs. The first part of the report shows the header on top and then shows the difference in warning summary. The second part of the report displays all regressions and improvements in detail. The following example shows the usage of -basepdb <basepdbname> detailed diff report with the -alloption:

Example 34 Generating detailed diff report with the header

$ cadvise report -pdb tmp.pdb -basepdb tmp1.pdb -all

Report generated using "HP Code Advisor C.XX.XX [Release Date]" on <Machine Name> at <Time>

Report command line: "Report Command Line"

New Pdb:

tmp.pdb

Base Pdb:

tmp1.pdb

Regressions:

=>2549(2)

Improvements:

You also have the flexibility of using the filtering options with this feature. If you use any filtering option in the command line, then the first step report is filtered and then the diff report is generated as shown in the following examples.

The following example shows the usage of -basepdb <basepdbname> detailed diff report with the -diagoption:
