Insufficient Space in /opt

[Nelson Ros]

Trying to install Oracle 10g r2.
Need to install HP ANSI C++ compiler (oracle
requirment). Procurred ANSI C++, however will not let me install because I have insufficient space in /opt directory. (system specifics follow).
My sysadmin allocated all remaining space to /oracle. Question ?
1. Can I de-allocate space from /oracle and then re-use/extend in /opt ? or
2. Is there a switch or command that will allow me to install the compiler in a different directory. ?
My initial guess is that I will have to re-install o/s, and re-apportion the disk space.
Hate to do this as HUPX came pre-installed. Have TAPE LIF image and Golden Image (of existing system)

Thanks

Sure, you can "de-allocate".

lvreduce -L {new size in MB} /dev/vg00/lvo19
newfs /dev/vg00/rlvol9

lvextend /dev/vg00/lvol6
umount /dev/vg00/lvol6
extendfs /dev/vg00/rlvol6

The trick is in getting /opt un-mounted. You will probably have to re-boot in single user mode in order to accomplish this.

Pete
Thanks

I assume that the newfs command will wipe out all the /oracle directory ???

No problem rebooting in sibgle user mode as long as I do not have to do a "restore" of the o/s I am happy....

Here is a description of the filesystem type

/dev/vg00/lvol3 / vxfs delaylog 0 1
/dev/vg00/lvol1 /stand hfs defaults 0 1
/dev/vg00/lvol4 /tmp vxfs delaylog 0 2
/dev/vg00/lvol5 /home vxfs delaylog 0 2
/dev/vg00/lvol6 /opt vxfs delaylog 0 2
/dev/vg00/lvol7 /usr vxfs delaylog 0 2
/dev/vg00/lvol8 /var vxfs delaylog 0 2
/dev/vg00/lvo19 /oracle vxfs delaylog,nodatainlog,largefiles,rw,suid 0 2

Note that /opt is vxfs.
Does this mean that I do not have to reboot in single user mode as /lvol17 is vxfs ?

Only if you have OnlineJFS. Do a "swlist |grep -i online" to check.

If you have online JFS, you won't need to. However, since you are dealing with the ROOTvg and are doing a reduction as well, you may want to reboot to single user just to ensure that you have all the processes shutdown.

[Nelson Ros]

Thank you..(both of you)

I do not have the required software.
To install it would probably run me into the same problem.

Since my "HP-UX" training happened over 10 years ago,(OLD SCHOOL)I think i'll just do it the old fashioned way via command line and single user mode reboot.

Great response time from both of you. I appreciate the help and will assign points ASAP

thanks Again

>Need to install HP ANSI C++ compiler (oracle requirement).

You don't need this unless you are installing Oracle Apps.

>2. Is there a switch or command that will allow me to install the compiler in a different directory?

Sure, you can install into an alternate root and then symlink /opt/aCC to that directory.
You won't get /opt/aCC added to /etc/PATH and /etc/MANPATH though.

Of course you can create a symlink from /opt/aCC to another directory and then install normally.

Thank you all
