How does capped-memory work in zones?
I have 32G of memory and 10 zones.
I want about physical=4G and swap=4G in each zone.
Is this possible? I am going over the 32G. (1 Reply)
Guys,
How to find memory size on solaris zone? We have total 16 GB and have 3 zone, but not sure how to find memory size for each zone? Please help. (1 Reply)
We have several containers on one machine and would like to reserve some memory for the global zone. capped-memory only allows max physical/swap and setting a max on each container isn't an option. The server has 32GB physical and 30GB swap. Currently there are ten containers on it. Normally... (6 Replies)
Is it possible to restrict physical memory in solaris zone with zone.max-locked-memory just like we can do with rcapd ? I do not want to used rcapd (1 Reply)
hi guys
the monitoring team is using a tool for monitoring linux boxes and they set an alarm for swap memory to 10%(critical) I really has no idea when swap memory usage is high....
Can someone recommend me a threshold for this? when is warning or critical and this parameters can affect... (3 Replies)
We have a zone configured in our X4600 machine with memory capped to 16GB. Most of the time zone is running with high physical memory utilization. It seems from "top" command shows that the command "kernel" is locks 15GB phy. memory and not using swap memory. Whenever we restart the application... (2 Replies)
If I understand your question correctly, you are asking for an explanation of Solaris memory manager. You'd better ask Oracle that question because you are talking about Solaris kernel internals.
The operating system kernel has no reason to kick a process's memory set out of real memory until... (4 Replies)

zprint
ZPRINT(1) BSD General Commands Manual ZPRINT(1)NAME
zprint -- show information about kernel zones
SYNOPSIS
zprint [-cdhlLstw] [name]
DESCRIPTION
zprint displays data about Mach zones (allocation buckets). By default, zprint will print out information about all Mach zones. If the
optional name is specified, zprint will print information about each zone for which name is a substring of the zone's name.
zprint interprets the following options:
-c (Default) zprint prints zone info in columns. Long zone names are truncated with '$', and spaces are replaced with '.', to allow
for sorting by column. Pageable and collectible zones are shown with 'P' and 'C' on the far right, respectively. Zones with pre-
posterously large maximum sizes are shown with '----' in the max size and max num elts fields.
-d Display deltas over time, showing any zones that have achieved a new maximum current allocation size during the interval. If the
total allocation sizes are being displayed for the zones in question, it will also display the deltas if the total allocations
have doubled.
-h (Default) Shows headings for the columns printed with the -c option. It may be useful to override this option when sorting by
column.
-l (Default) Show all wired memory information after the zone information.
-L Do not show all wired memory information after the zone information.
-s zprint sorts the zones, showing the zone wasting the most memory first.
-t For each zone, zprint calculates the total size of allocations from the zone over the life of the zone.
-w For each zone, zprint calculates how much space is allocated but not currently in use, the space wasted by the zone.
Any option (including default options) can be overridden by specifying the option in upper-case; for example, -C overrides the default option
-c.
DIAGNOSTICS
The zprint utility exits 0 on success, and >0 if an error occurs.
