about the sysconfigdb command!
i used the command sysconfigdb to modified the subsystem parameters
for example:
#sysconfigdb -m -f test rt
the content of file test
rt:
aio-max-num = 2048
aio-task-max-num = 2048
aio-max-retry = 2
need i to reboot the system to have the changes take effect immediately?
can i use the command sysconfig -r?
for example:
#sysconfigdb -m -f test rt
the content of file test
rt:
aio-max-num = 2048
aio-task-max-num = 2048
aio-max-retry = 2

can i use the command sysconfig -r?

Re: about the sysconfigdb command!
Hello,
You could issue the following command and have a look to the provided "op" item.
i.e
# sysconfig -Q rt | more
rt:
aio-max-num - type=INT op=CQ min_val=0 max_val=65535
aio-task-max-num - type=INT op=CQ min_val=0 max_val=2147483647
aio-listio-max-num - type=INT op=CQ min_val=64 max_val=256
aio-max-percent - type=INT op=CQ min_val=0 max_val=10
aio-max-retry - type=INT op=CQ min_val=0 max_val=256
aio-retry-scale - type=INT op=CQ min_val=1 max_val=1024
aio-socket-on-off - type=INT op=CQ min_val=0 max_val=1
sigqueue-max-num - type=INT op=CQ min_val=0 max_val=32767
rttimer-max-num - type=INT op=CRQ min_val=32 max_val=8192
aio-percpu-data - type=INT op=CQ min_val=0 max_val=1
rtsem-nsems-max - type=INT op=CQ min_val=256 max_val=32767
If in the "op" item the "R" char is missing then you need to reboot your host in order to reconfigure the parameter value.
Exemple:
# sysconfig -Q inet | grep tcp_keepal
tcp_keepalive_default - type=UINT op=CRQ min_val=0 max_val=1
In this case the tcp_keepalive_default parameter could be modify and the value is updated and reconfigured without rebooting.
In your case and depending on the Tru64 release, you should probably need to reboot.
I hope this helps and clarify the behaviour.

Re: about the sysconfigdb command!
in case of doubt use the dxkerneltuner application showing the boot and current value and if it can be set during runtime.
