Setup a JDBC Thin Application to test Fast Connection Failover

December 17, 2009 Leave a comment Go to comments

1. Software Requirments

  • java 1.5 or above
  • ojdbc14.jar and ons.jar
  • FCFExample.zip (From ID 433827.1 on metalink)

2. Hardware Configuration

  • Two Linux Server form RAC cluster nodes: vmrac1,vmrac2
  • A window XP machine acts as testing machine

Configuration on Testing Server 

3. Install the java binary on the XP machine.


4. Unzip FCFExample.zip to D:\FCF

5. Edit the fcfcache.properties as the following

# properties required for test
onsconfig=nodes=vmrac1-vip:6200,vmrac2-vip:6200 <– ONS configuration on the RAC cluster
url=jdbc:oracle:thin:@(DESCRIPTION= \
    (LOAD_BALANCE=yes) \
       (ADDRESS=(PROTOCOL=TCP)(HOST=vmrac1-vip)(PORT=1521)) \ <— Cluster Node1 VIP
       (ADDRESS=(PROTOCOL=TCP)(HOST=vmrac2-vip)(PORT=1521)) \<— Cluster Node2 VIP 

6. Put ojdbc14.jar and ons.jar onto D:\FCF

7. Compile the  FCFConnectionCacheExample.java

set CLASSPATH=ojdbc14.jar;ons.jar;. <-- Set the CLASSPATH
javac -cp %CLASSPATH% FCFConnectionCacheExample.java <-- Compile the source

Check ONS Configuration on Cluster Servers

8. Check ONS ports

[oracle@vmrac2 ~]$ $CRS_HOME/bin/onsctl ping
Number of onsconfiguration retrieved, numcfg = 2
   {node = vmrac1, port = 6200}
Adding remote host vmrac1:6200 <– ONS listening port on Cluster Node 1
   {node = vmrac2, port = 6200}
Setting remote port from OCR repository to 6200
Adding remote host vmrac2:6200<– ONS listening port on Cluster Node 2

ons is running … <– It is runing

9. Run the FCFConnectionCacheExample

D:\jdk1.5.0_07\bin\java -cp %CLASSPATH% FCFConnectionCacheExample.

    I also believe that mesothelioma is a unusual form of cancer
    malignancy that is normally found in individuals previously
    familiar with asbestos. Cancerous tissues form in the mesothelium, which is a protecting lining that covers
    most of the body’s bodily organs. These cells usually form inside the lining with the lungs, mid-section, or the sac that encircles one’s heart.
    Thanks for revealing your ideas.
