Do you know the name of the original volume group?

Did you do a vgexport on the original system?

Quote:

To move the database: a.Shut down the database. Making a backup copy is highly recommended. b.For a file system-based database, unmount the file systems using the umount command. c.Deactivate the volume groups using the vgchange command. d.Create a map file which will facilitate moving the volume groups to the HP Integrity server by using the vgexport command. Use the -p (preview) option to avoid expunging the volume group from the HP 9000 server (to allow for backtracking if necessary). HP also recommends using the -s (shared) option; it was designed to simplify the process of moving volume groups between the nodes of a clustered system, but is also available for non-clustered systems. The following is an example of using vgexport to create a map file named mapfilefor the volume group vgORA: vgexport -p -m mapfile -s /dev/vgORA e.Copy the map file to the HP Integrity (where it will be used by a vgimport command to recreate the volume group). f.Provide the HP Integrity access to the disks containing the database. This could require physically re-cabling the disks from the HP 9000 to the HP Integrity. You can also accomplish this by reconfiguring your SAN, or in the case of a disk array, reconfiguring the LUNs to be visible to the HP Integrity. On the HP Integrity, perform an ioscan and then an insf to initiate configuration of the newly added disks or LUNs. g.Import the volume groups using the map files, and the volume group directories and group files you created earlier. For example, use: vgimport -m mapfile -s /dev/vgORA h.Change the volume group special files to be owned by the same owner and group as on the HP 9000 server, and ensure correct permissions: chown -R oracle:dba /dev/vgracchmod 644 /dev/vgrac/* i.Activate the volume groups using vgchange -a y. For a clustered system, you will need to take the extra steps to change the volumegroups to permit sharing (using vgchange -c y -S y) and then activate the volumegroup in shared mode (using vgchange -a s). j.If your database is implemented using file systems, mount the logical volumes contained in the volume groups you just activated (for example, mount /dev/vgORA/lv01 /ora01).

net::ldapi

Net::LDAPI(3)						User Contributed Perl Documentation					     Net::LDAPI(3)

NAME

       Net::LDAPI - use LDAP over a UNIX domain socket

SYNOPSIS

	use Net::LDAPI;

	$ldapi = Net::LDAPI->new('/var/run/ldapi');

	# alternate way
	use Net::LDAP;

	$ldapi = Net::LDAP->new('ldapi://');

DESCRIPTION

       Communicate using the LDAP protocol to a directory server using a UNIX domain socket. This mechanism is non-standard, UNIX-specific and not
       widely supported.

       All the normal "Net::LDAP" methods can be used with a "Net::LDAPI" object; see Net::LDAP for details.

CONSTRUCTOR

       new ( [SOCKPATH] )
	   Create a new connection. SOCKPATH can optionally be specified, to specify the location of the UNIX domain socket to connect to.

	   If SOCKPATH is not given, the environment variable "LDAPI_SOCK" is evaluated, and if that does not exist, the value "/var/run/ldapi" is
	   used.

	   See "new" in Net::LDAP for further details.

SEE ALSO

       Net::LDAP, IO::Socket::UNIX

BUGS

       None yet.
