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. |
