NAME

6       poold - automated resource pools partitioning daemon
7

SYNOPSIS

9       poold [-l level]
10
11

DESCRIPTION

13       poold provides automated resource partitioning facilities. poold can be
14       enabled or disabled using  the  Solaris  Service  Management  Facility,
15       smf(5).  poold  requires  the  Resource  Pools facility to be active in
16       order to operate.
17
18
19       The dynamic resource pools service's fault management resource  identi‐
20       fier (FMRI) is:
21
22         svc:/system/pools/dynamic
23
24
25
26       The resource pools service's FMRI is:
27
28         svc:/system/pools
29
30
31
32       poold's configuration details are held in a libpool(3LIB) configuration
33       and you can access all customizable behavior from this configuration.
34
35
36       poold periodically examines the load on the system and decides  whether
37       intervention  is  required  to maintain optimal system performance with
38       respect to resource consumption. poold also responds to externally ini‐
39       tiated (with respect to poold) changes of either resource configuration
40       or objectives.
41
42
43       If intervention is required, poold attempts to reallocate the available
44       resources to ensure that performance objectives are satisfied. If it is
45       not possible for poold to meet performance objectives with  the  avail‐
46       able  resources,  then a message is written to the log. poold allocates
47       scarce resources according to the objectives configured by the adminis‐
48       trator.  The  system  administrator must determine which resource pools
49       are most deserving of scarce resource and  indicate  this  through  the
50       importance of resource pools and objectives.

OPTIONS

53       The following options are supported:
54
55       -l level    Specify the vebosity level for logging information.
56
57                   Specify  level  as ALERT, CRIT, ERR, WARNING, NOTICE, INFO,
58                   and DEBUG. If level is not supplied, then the default  log‐

63
64
65                   CRIT       Critical conditions, such as hard device errors.
66
67
68                   ERR        Errors.
69
70
71                   WARNING    Warning messages.

74                   NOTICE      Conditions that are not error  conditions,  but
75                              that may require special handling.
76
77
78                   INFO       Informational messages.
79

81                   DEBUG      Messages  that  contain  information normally of
82                              use only when debugging a program.
83
84
85

91       Example 1 Modifying the Default Logging Level
92
93
94       The following command modifies the default logging level to ERR:

98
99
100
101       Example 2 Enabling Dynamic Resource Pools
102
103
104       The following command enables dynamic resource pools:
105
106
