Grid Control Problem


Today I noticed that my Grid Control was slower than normally, and when I try to connect to the Grid Control Console, sometimes I can connect, but other

times I get the following error:

Error

Authentication failed. Verify username/password that you have provided. If you believe you entered correct credentials, your account may have been locked,

contact system administrator to unlock your account.

Weird, I’m not typing bad my password, what could be wrong?

The last change I made in my server was modifying the file /etc/hosts , because the name of my machine was pointing to 127.0.0.1, and I wanted to change it

to his real IP. It looks that something went wrong.

Another symptom was revealed when I used the command netstat:

[root@superlopez ~]# netstat -punta | wc -l
42487

And 1 minute later I execute it again…

[root@superlopez ~]# netstat -punta | wc -l
62881

Definitely something was wrong, almost all the connections were of the following kind:

tcp        0      0 127.0.0.1:45118             127.0.0.1:6103              TIME_WAIT   –

Ok, first step, this error must being logged somewhere, let’s search all the logs in the server and order it chronolocally:

[root@superlopez ~]# ls -larth $(find / -name “*.log” 2>/dev/null)
-rw-rw—- 1 oracle oinstall  18M may  4 08:23 /u01/oracle/app/10.2.0.4/oms10g/j2ee/home/log/home_default_island_1/server.log
-rw-rw—- 1 oracle oinstall  18M may  4 08:23 /u01/oracle/app/grid/oms10g/j2ee/OCMRepeater/log/OCMRepeater_default_island_1/server.log
-rw-rw—- 1 oracle oinstall  18M may  4 08:23 /u01/oracle/app/grid/oms10g/j2ee/OC4J_EMPROV/log/OC4J_EMPROV_default_island_1/server.log
-rw——- 1 oracle oinstall  18M may  4 08:23 /u01/oracle/app/grid/oms10g/j2ee/home/log/home_default_island_1/server.log
-rw-r—– 1 oracle oinstall  51M may  4 08:23 /san/datos/CATRMAN/redo02.log
-rw-rw—- 1 oracle oinstall  31M may  4 08:23 /u01/oracle/app/grid/oms10g/j2ee/OC4J_EM/log/OC4J_EM_default_island_1/default-web-access.log

These are the logs written in the last minute. I don’t think the poor redo log gives me any information, but the other logs might insight me.

… But none of them gave me any information at all. However, the log /u01/oracle/app/10.2.0.4/oms10g/opmn/logs/ons.log shows the following error several

times, and the log occupies 1Gb:

10/05/03 12:44:08 [4] Falta el factor de formato de la conexión local 0,127.0.0.1,6103
<unknown>

So, there is a problem with the port 6103. After googling a bit, I modified the file /u01/oracle/app/10.2.0.4/opmn/conf/ons.config and changed:

localport=6103
remoteport=6203
loglevel=3

to

localport=6115
remoteport=6205
loglevel=3

After that I rebooted…

[root@superlopez ~]# netstat -punta | wc -l
177

Problem solved! It looks like the port 6103 was in onflict with another service, so after changing the port in the previous file, everything started working

fine.

One problem less…
