  If your database is not using ASM or is not a RAC database u don't need the ocssd daemon running. I had a similar issue at a customer site 6 months ago on and we just turned ocssd off.

On the physical standby server, I don't collect OS stats, but total swap size (not swap available...TOTAL swap size) was 450-MB a few minutes ago and the size of the ocssd process was 6-GB. I just killed ocssd and total swap size jumped back up to 6.6-GB and seems to be rising steadily and is now at 6.9-GB. The network admin just ran another port scan on the logical standby server and total swap size plunged from 14-GB to 2-GB and seems to be steadily dropping. At the same time, the size of the ocssd process jumped from 30-MB to 12-GB. So, we need to figure out the relationship between the port scan, swap, and the ocssd daemon.

Thanks for responding.

We have some large enterprise level servers, E20K, E6900 as well as small servers, like v490, etc. running Oracle9i and Oracle 10g databases but I have not experienced this issue on our servers. I can monitor some servers to see if we are leaking swap space.

Subject: Swap Leak on Solaris 9 and a posting from last year by Grzegorz Goryszewski     

This past weekend, we patched our Production Sun servers with Solaris patches and the Oracle DST patch. On two of those servers which host standby databases (one server for physical, one server for logical), we are seeing swap space gradually drop down to almost nothing from 14-GB. Just had to re-boot one of the servers and the other one is not far behind. A Google search came up with a posting on this list from last year from Grzegorz Goryszewski who was experiencing the same thing. Grzegorz, are you monitoring this list still? Did you find a solution? Has anyone else seen this behavior?
