These two nodes, now are they in an HACMP cluster or not? If so nothing easier than what you ask for. You put that NFS share into a shared VG on SAN and mount it eg. in /sharedFS_jfs2 on the home node where the VG is active. Through cluster NFS exports and statements in the RG definition you export it to both nodes. On both nodes then you mount homenode:/sharedFS_jfs2 to /sharedFS and have the share available on both sides with the same path. = NFS cross mounts.
Of course the service IP of $homenode needs to be part of the RG as well, so in case it fails over to nodeB that system will still be able to access the share. Having the VG with the same major number on both nodes eliminates the need for remounts after failover... The RG needs to varyon VGs and mount file systems before starting TCPIP related stuff like the exporting.

Hi. Does anyone know by how much a text size of an executable(on ibm) would grow if you link one shared object(library)? Is it a constant number or it depends on a .so that is linked? (3 Replies)

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

remnode
remnode(8) System Manager's Manual remnode(8)
Name
remnode - remove one or more entries from the nodes database
Syntax
/etc/remnode [ node ]
Description
For each given node argument, deletes the corresponding node entry (or entries) from the nodes database. The nodes database is the one used
by DECnet. The node is either the node address or the node name for each node entry that you want to delete. Note, you can specify more
than one node argument in a single command.
A node address is a decimal integer in the range of 1 to 1023 for single area networks, or has the format a.n for multiarea networks, where
a is the network area number (a decimal integer in the range of 2 to 63) and n is the node number (a decimal integer in the range of 1 to
1023).
A node name can be from one to six alphanumeric characters, including at least one letter.
Examples
This command removes the entries for nodes 44.70 and Mynode from the nodes database:
# /etc/remnode 44.70 mynode <RET>
This command removes the entry for node lttwi from the nodes database:
# /etc/remnode lttwi <RET>
