Error Buiding New Kernel

[Chris Hinnen]

I am now having another problem. I am trying to increase the number of semaphores allowed because Oracle will not start. But when rebuilding the kernel I get the following error:

Cannot build a kernel using /usr/sbin/config. The standard output of the command is shown below:
Usage: bstab input_data symbol_cnt strtbl_size kernel_file output_file

Stop.
config: make did an exit(1)

The command exited with exitcode -71.

Any ideas?

Chris,

To rebuild the HP-UX kernal, do the following:

1. cd /stand/build
2. create the kernal parameter system file
/usr/lbin/sysadm/system_prep -s system
3. make your changes to the system file
vi system
4. build the new kernal
/usr/sbin/mk_kernel -s ./system
5. back up the old kernel and sys files
mv /stan/system /stand/system.prev
mv /stand/vmunix /stand/vmunix.prev
6. install the new kernel
cp /stand/build/system /stand
cp /stand/build/vmunix_test /stand/vmunix
7. reboot system
8. verify the kernel changes using sysdef

Check out the sysdef and mk_kernel man pages. You can also use the SAM. Hopefully this helps you.

I used SAM to increase the parameter and had it rebuild the kernel for me but that is when I got this error message. Would doing it manually be any different?

Yes - building the kernel manually is different than through SAM. If you can do it manually then there is a bug in SAM and no problem on your system... I have experienced that situation once - a driver affected the ability for SAM to do the compile but it could be done without SAM...good luck and let us know.
thanks,

Chris,

Peggy is right. There have been some problems in the past using SAM to rebuild the kernel. If you have all the latest patches/updates for your server, SAM should work. I have successfully rebuilt the kernel using SAM in the past but I prefer to use the manual method.

Did we help at all? Or did you find an answer elsewhere? Is your problem fixed? I am always curious when someone runs into trouble. Will you post what happened and if we did help please assign points so we know - this helps the whole forum, especially newbies who might run into the same problem. I really do want to know what the outcome of your situation was - we can all learn from these problems we run into. Thanks,
Peggy

Yes rebuilding the kernel by hand seemed to fix the problem. The kernel built fine and everything is OK now. Thanks for the help.
