Simpler Navigation coming for Servers and Operating Systems
Coming soon: a much simpler Servers and Operating Systems section of the Community. We will combine many of the older boards, and you won't have to click through so many levels to get at the information you need. If you are looking for an older board and do not find it, check the consolidated boards, as the posts are still there.

Kernel parameter MAXPHYS

I have a series of processes of Oracle that you/they are taking more than that foreseen. In the documentation of the database I have observed that it is recommended to modify the parameter maxphys to optimize the accesses I/O

However, in the documentation of HP only encounter references to the parameter scsi_maxphys. In my systems the connection to disks is carried out by means of fiber cards for that that not you if it is the correct parameter or if he/she should be defined another.

The operating system version that I have is HP-UX 11.0

Thank you ahead of time.
