How to add new Kernel Subsystem and its attribute

Hi,

I have to installaed Oracle10g Release 2 on OS hp tru64. There for I have to add Kerenl subsystem rdg with its attribute. I am using a text editor file like newkernel.txt
-----------
rdg:
msg_size = 32768
max_objs = 5120
max_async_req = 256
max_sessions = 500
rdg_max_auto_msg_wires = 0
rdg_auto_msg_wires = 0
-----------------
and run following command to add kernel parameters.

/sbin/sysconfigdb -m -f newkernel.txt
and restart the system.

1) Problem is that when I view the rdg subsystem parameter from kernel tuner option. There is no rdg subsystem entery exist. But the rdg subsystem exist sysconfigtab file.

2) When I install the Oracle10gR2 the following error occured.
-----------------------------------------
Checking for msg_size=32768; found no entry. Failed <<<<
Checking for max_objs=5120; found no entry. Failed <<<<

Re: How to add new Kernel Subsystem and its attribute

Is it a standalone system or cluster?
For standalone system there is NO rdg subsystem!
This is for TRU CLUSTER!
Please, post more details.

Hi Junaid,

This just goes to show how poor Oracle's quality control appears to be on Tru64 these days :-(

As Vladimir states the rdg is only present on a clustered system. However the Oracle installer still checks for these parameters on a standalone system. The installation guide also tells you to set them !

The installer will allow you to continue without them set however. Just click Next to proceed.

Hope this helps,

Regards,

Rob

Re: How to add new Kernel Subsystem and its attribute

In our case with 10g the installer complained about patch kits not being present when they were. I think it checked for PK3 when we have PK5 installed. It's not smart enough to check to later patch kits.

Just had to keep ignoring the warnings.
