The svmon did not show much, seems this sort is an > AIX 5.3 thing; try this one and check which has/have by far the highest value in the column "Pgsp":
I would set parameters as recommended in my former post and see if the paging stops, hopefully.
This may take some time since there is still a lot out on the disk that needs at least to be paged in when it's needed. To speed this up, reboot the box after setting the following command...
You can set them online with the following command:
The -p makes it permanent and survives a boot.
I am running HP-UX B.11.11.
I'm increasing a parameter for a database engine so that it uses more memory to buffer the disk drive (to speed up performance). I have over 5GB of memory not being used.
But when I try to start the DB with the increased buffer parameter I get told.

Hi,
I'm trying to learn how to manage memory when I have to deal with lots of data.
Basically I'm indexing a huge file (5GB, but it can be bigger), by creating tables that

once (yep!) but of course the... (1 Reply)

good morning,
how I can know how much total and free memory I have in my AIX 5.3 server, and this is shown in megabytes or gigabytes?
Thank you very much. (4 Replies)

pg2
pg2(3erl) Erlang Module Definition pg2(3erl)NAME
pg2 - Distributed Named Process Groups
DESCRIPTION
This module implements process groups. The groups in this module differ from the groups in the module pg in several ways. In pg , each mes-
sage is sent to all members in the group. In this module, each message may be sent to one, some, or all members.
A group of processes can be accessed by a common name. For example, if there is a group named foobar , there can be a set of processes
(which can be located on different nodes) which are all members of the group foobar . There are no special functions for sending a message
to the group. Instead, client functions should be written with the functions get_members/1 and get_local_members/1 to find out which pro-
cesses are members of the group. Then the message can be sent to one or more members of the group.
If a member terminates, it is automatically removed from the group.
Warning:
This module is used by the disk_log module for managing distributed disk logs. The disk log names are used as group names, which means that
some action may need to be taken to avoid name clashes.
EXPORTS
create(Name) -> void()
Types Name = term()
Creates a new, empty process group. The group is globally visible on all nodes. If the group exists, nothing happens.
delete(Name) -> void()
Types Name = term()
Deletes a process group.
get_closest_pid(Name) -> Pid | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_process, Name} | {no_such_group, Name}
This is a useful dispatch function which can be used from client functions. It returns a process on the local node, if such a
process exist. Otherwise, it chooses one randomly.
get_members(Name) -> [Pid] | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Returns all processes in the group Name . This function should be used from within a client function that accesses the group. It is
therefore optimized for speed.
get_local_members(Name) -> [Pid] | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Returns all processes running on the local node in the group Name . This function should to be used from within a client function
that accesses the group. It is therefore optimized for speed.
join(Name, Pid) -> ok | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Joins the process Pid to the group Name . A process can join a group several times; it must then leave the group the same number of
times.
leave(Name, Pid) -> ok | {error, Reason}
Types Name = term()
Pid = pid()
Reason = {no_such_group, Name}
Makes the process Pid leave the group Name . If the process is not a member of the group, ok is returned.
which_groups() -> [Name]
Types Name = term()
Returns a list of all known groups.
start()
start_link() -> {ok, Pid} | {error, Reason}
Types Pid = pid()
Reason = term()
Starts the pg2 server. Normally, the server does not need to be started explicitly, as it is started dynamically if it is needed.
This is useful during development, but in a target system the server should be started explicitly. Use configuration parameters for
kernel for this.
