How to create High Availability Port with idc protocol ?
Purpose : Using
balance software , HA port is created with idc protocol . So this
will help to load balance idc port in clustered domain .
Steps :
1.Install balance
2.run balance
command
Detailed Steps :
1. Download balance
from : https://www.inlab.de/balance.html
2. Make and Install
it
cd balance-3.56
[root@LB
balance-3.56]# make
gcc -O2 -Wall
-Wstrict-prototypes -Wuninitialized -I. -c balance.c
balance.c: In
function ‘stream’:
balance.c:910:
warning: pointer targets in passing argument 1 of ‘hash_fold’
differ in signedness
./balance.h:133:
note: expected ‘char *’ but argument is of type ‘unsigned char
*’
balance.c: In
function ‘main’:
balance.c:1813:
warning: pointer targets in passing argument 1 of ‘hash_fold’
differ in signedness
./balance.h:133:
note: expected ‘char *’ but argument is of type ‘unsigned char
*’
gcc -O2 -Wall
-Wstrict-prototypes -Wuninitialized -I. -c butils.c
gcc -O2 -Wall
-Wstrict-prototypes -Wuninitialized -I. -o balance balance.o
butils.o
[root@LB
balance-3.56]# make install
install -o root -g root -m 755 balance \
/usr/sbin/balance
install -o root -g root -m 755 balance.1 \
/usr/sbin/../man/man1
install: cannot create regular file `/usr/sbin/../man/man1': No such
file or directory
3.Verify by running
balance commad
[root@myserver
~]balance

4.Run the balance
command with idc server
Example : balance -b
::ffff:<LB> -B <LBHOSTNAME> <LBPORT> <IP1:POR1>
<IP2:PORT2>
[root@myserver
~]# netstat -anp | grep 4444
[root@LB ]#
balance -b ::ffff:10.111.11.111 -B LBHOST 4444 10.111.11.121:4453
10.111.11.122:4997
[root@LB ]#
netstat -anp | grep 4444
tcp 0
0 ::ffff:10.111.11.111:4444 :::* LISTEN
23705/balance
6. Verify it
Here for testing
purpose I am connecting two different WCC servers , which is having
different autoprefix and running CHECKIN_UNIVERSAL . Make sure that
admin server should be up and running while connecting via idc
protocol
url=
10.111.11.111:4444
[sterin@sterinlap test]$ java TestRIDCCheckin
dDocName is SOURCEFF001052
[sterin@sterinlap test]$ java TestRIDCCheckin
dDocName is STJACOBPC1IDCO001205
So It will connect
in round robin fashion . If one server is down, then automatically
connect to other one
