Hi,

this istance has got this error message in dev_icm:

[Thr 01] Wed Oct 26 11:29:56 2011

[Thr 01] Parameter system/type has value: "J2EE"

[Thr 01] *** WARNING => The maximum number of sockets supported on this host is 250.

This is less than the number of sockets configured in parameter icm/max_sockets (2048) [icxxman_mt.c 3334]

Ok... icm/max_sockets is quite good...

and limit output is:

cputime unlimited

filesize unlimited

datasize unlimited

stacksize 10240 kbytes

coredumpsize unlimited

descriptors 4096

memorysize unlimited

I read SAP note 737625 descriptors should be already OK, have you got any idea?

Regards.

Solaris 10 doesn't use /etc/system but uses projects.

Check

Note 724713 - parameter settings for Solaris 10

and make sure the parameter process.max-file-descriptor is set in the project and that the user <sid>adm is assigned to that project in /etc/user_attr

Added changes required for Solaris 10 Update 10 (Solaris 10 8/11):

The "priv" level of process.max-file-descriptor is no longer needed.

And you're using Solaris 10 8/11?

check with

cat /etc/release

Hello,

The 'limit' output is in 'cshell' and with 'sidadm' user ?

Value of 'descriptors' - 4096 seems OK here but if you still discuss with your unix team to confirm. I have heard about soft and hard limits in AIX, may be something similar in Solaris ?

Or the 'limit' might had been edited and the sap instance might not been restarted after that ?

Thanks

Yes.

I don't know it. I think no...

No changes.
