Thanks!
I believe it's somehow related to the high connection count.

Hi all,
Without oracle tunning I understand that oracle processes always run on a single CPU at a time (the prstat output always show 1 CPU number) even on multi-processor hardware.
Is it correct?

Hi,
I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory.
I'm using "top" to get the free memory and the memory usage of processes.
Thanks. (3 Replies)

evmconncheck
EvmConnCheck(3) Library Functions Manual EvmConnCheck(3)
NAME
EvmConnCheck(), EvmConnWait(), EvmConnDispatch(), EvmConnFlush() - maintain connection with the EVM daemon
SYNOPSIS
Library
EVM Support Library
Parameters
connection The EVM connection that is to be monitored. See the EvmConnCreate(3) manpage.
IOWaiting This is the return operand. Possible values for this operand are the following:
There is no outstanding I/O activity on the connection.
There is outstanding I/O activity on the connection.
The client needs to call to handle the outstanding activity.
timeout If the timeout value is NULL, it specifies that is to wait until there is activity on the connection. If the timeout value is
not NULL, it specifies the amount of time that waits for activity on the connection.
count Receives a count of messages queued for sending to the EVM daemon.
DESCRIPTION
The routine checks whether there is any I/O activity outstanding on the connection. If there is activity, IOWaiting is set to The program
is to then call to handle it. If there is no outstanding I/O activity, IOWaiting is set to An response from this function does not guaran-
tee that an event has arrived. An response simply means that there is a message on the connection that needs to be handled.
The routine blocks until activity is detected on the connection. If timeout is not NULL, it specifies the amount of time that the function
waits for activity on the connection before returning with a status of
The routine handles one incoming I/O message on the connection, calling the client's callback function as needed. If there is no message
awaiting processing, the function returns immediately. Calling this function is not guaranteed to invoke the connection's callback func-
tion. If the callback is invoked, it is not necessarily true that an event has arrived.
The routine attempts to send to the EVM daemon any messages that are queued for output as a result of earlier calls on a connection that is
marked as a non-blocking connection. The routine continues to send messages from the queue, until either all messages have been sent or
until the send buffer is full. On return, if the count output parameter is a number greater than zero, then that number is the number of
messages still queued for sending. returns See EvmConnControl(3) for more information.
RETURN VALUE
The operation completed without error.
One of the arguments to the function is invalid.
A value in a structure member is invalid.
An operation failed because an attempt to acquire heap memory failed.
A read error occurred while reading from the EVM daemon connection.
A write error occurred while writing to the EVM daemon connection.
An error occurred on the EVM connection. Invoke
to destroy the connection.
A timeout period expired.
The current operation was interrupted by receipt of a signal.
One or more messages is queued for sending to the EVM daemon.
ERRORS
The value of is not set.
FILES
Default pathname for the domain socket.
