Transparent Sdp Configuration - HP 376227-B21 - ProLiant InfiniBand 4x Fabric Copper Switch Implementation Manual

Transparent SDP configuration

The following steps are very crucial and require absolute path statements; any typing errors could
render the system inoperable. The preload file, ld.so.preload points to a library, libsdp.so, to be
loaded during system startup. If the path is incorrect, library name is misspelled, or library does not
exist a reinstall of the operating system may be required.
On the database server
1. Verify the existence of /lib/libsdp.so
2. Stop the database
3. Stop the listener
4. # echo "/lib/libsdp.so" > /etc/ld.so.preload
5. # echo "match listen *:1521" >>/usr/local/topspin/etc/libsdp.conf
6. # echo "match destination *:1521" >> /usr/local/topspin/etc/libsdp.conf
7. Edit the listener.ora file to include the private interconnect settings.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = SDP) (HOST = dbhostname_IB) (PORT = 1521))
)
)
NET_ASYNC_IO=FALSE
SDP_ASYNC_IO=FALSE
8. Edit the sqlnet.ora file to include the following lines.
NET_ASYNC_IO=FALSE
SDP_ASYNC_IO=FALSE
9. Start the database
10. Start the listener
11. Check /proc/topspin/sdp/conn_main (should have 3 entries)
On the application server
1. Verify the existence of /lib/libsdp.so
2. # echo "/lib/libsdp.so" > /etc/ld.so.preload
3. # echo "match listen *:1521" >>/usr/local/topspin/etc/libsdp.conf
4. # echo "match destination *:1521" >> /usr/local/topspin/etc/libsdp.conf
5. Edit the tnsnames.ora file to included the private interconnect settings.
