DB2 - Problem description

Problem IC79237 Status: Closed

ADD VMSTAT -P IN DB2COS_PERF ON SOLARIS

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
In Solaris system, pi/po columns from vmstat include 
Executable/Anonymous/FileSystem. In AIX/HP and Linux, we check 
pi/po column for evidence of system paging, however in Solaris, 
pi/po column shows the number including both process pages and 
file system pages. So in the current db2fodc code, we only 
capture "vmstat" output, and the pi/po will be misleading in 
Solaris since it doesn't only show process paging.

Solution
In Solaris system, pi/po columns from vmstat include 
Executable/Anonymous/FileSystem. In AIX/HP and Linux, we check 
pi/po column for evidence of system paging, however in Solaris, 
pi/po column shows the number including both process pages and 
file system pages. So in the current db2fodc code, we only 
capture "vmstat" output, and the pi/po will be misleading in 
Solaris since it doesn't only show process paging.
