You have to be able to quantify what you are seeing, we cannot help with really vague questions because we will start asking a bunch of questions about things like this:
For example:
1. is free memory unavailable?
2. how many processes are there and how many process slots are free?
3. are there lots of network connections in the TIMED_WAIT status?
4. are there a few processes that are using lots of resources?
And keep going until there is enough information to help. Consider putting together a much better question with lots of information based on problems you see in the system.
The bigger the process, the longer takes the fork.
Oracle DB processes might be a little better because they use a large portion of "shared memory".
Since also Solaris is from Oracle, you can consider analysis method/tools from Oracle.
Also OS patches often boost performance.
Also you can monitor your system.
E.g. on the command line do
you can likely see a bottle neck: a big value in the "b" column means a slow disk, a big value in the "r" column means too much work for the CPU.
If you have a slow CPU, you can look how CPU time is distributed between "sy"s=kernel and "us"er=processes, and hopefully something is left for "id"le. (These values are in percent and sum up to 100.)
If you have a slow disk, you can break down this further with
or with the OS disk names (but long names are truncated)
Looking for
is a good idea because these processes are waiting for the client to re-open the connection, they cannot be used for another client.
If there are too many processes in TIME_WAIT it can improve by tuning it down, say from
60000 reduce it to 30000

Hi all,
Solaris is working very slow as login to solaris takes time say after 10 to 15 mins we get the login prompt back after logging in as oracle account/other account.
This causes most Batch run delays(DWHouse jobs) scheduled through cronjobs.
Where should one look for such issues to... (3 Replies)
