Re: difference/relation between OnlineJFS and VxFS
vxlicense was the old ( pre version 3.5 ) license reporting tool, vxlicrep is the new reporting tool. If you have upgraded from 3.2 to 3.5 or higher, you will have both tools on your system.
---
VxVM 3.5 introduces a new licensing package, VRTSvlic, that is common to all new
VERITAS products. The VRTSvlic package replaces the functionality of the VRTSlic
package that was used in VxVM 3.2 and earlier releases. The following table lists
equivalency between licensing commands in VRTSlic and VRTSvlic.
---
You should retain the old VRTSlic package on your system if it is required by
any installed VERITAS products other than VxVM.

Re: difference/relation between OnlineJFS and VxFS
system exhibits fast recovery features. HP OnLineJFS (Advanced JFS) is an
extension to the base JFS and can be managed online (without unmounting). For
example, you can extend or shrink the file system without unmounting it.
Advanced JFS can also be defragmented and reorganized while it is in use. HP
OnlineJFS is not included with the standard HP-UX distribution and must be
purchased separately. A disadvantage of JFS is that the HP-UX kernel can't
reside on it.
Like HFS, JFS also maintains multiple copies of the superblock, but these are not
stored in any file. JFS keeps a record of these copies automatically. JFS keeps a
record of all transactions to the file system metadata area in an intent log. The
intent log is used for system recovery in case of a system crash. If a file system
update is completed successfully, a "done record" is written to the intent log
showing that this update request was successful. In case of a system crash, the
intent log is consulted and the file system brought to the stable state by removing
all unsuccessful transactions with the help of the intent log.
Another big advantage of JFS over HFS is that it creates inodes dynamically. So
if the inode table is full but there is still space on the file system, JFS can create
new inodes automatically.
Like HFS, JFS also divides the file system in JFS blocks. By default, the size of
each block is 1 KByte. JFS allocates a group of blocks when you create a new
file. This group of blocks is called an extent. If the file size grows, JFS tries to
allocate contiguous blocks to the file, thus increasing the size of the file extent.
However, if the contiguous blocks are not available, JFS creates a new extent
and allocates it to the file.

Re: difference/relation between OnlineJFS and VxFS
I believe this isn't true for IPF, /stand/ is vxfs.

"Like HFS, JFS also divides the file system in JFS blocks. By default, the size of

"If the file size grows, JFS tries to

Re: difference/relation between OnlineJFS and VxFS
> what is this IPF or /stand/is?
IPF = Itanium Processor Family (as opposed to HP's proprietary PA-RISC series)
The punctuation mislead you. The '/stand' mountpoint is an HFS filesystem on PA-RISC but can be a VxFS one on Itanium processors beginning at 11.23.
Itanium processors are also referred to as "IA64 - Itanium Architecture. 64-bit.

-NOT true always.
This can be confusing. HP's OnlineJFS is *always* a purchased product. The 'standard' distribution does not include the OnlineJFS product. However, HP marketing has decided to bundle certain extra-cost products into operating environments so an Enterprise or Mission Critical Operating Environment is really a single product containing the core HP-UX plus extra-cost products like OnlineJFS. So you still have to pay for OnlineJFS, the difference being whether it is a separate purchase or included in a (higher priced) special bundle.
