The server cannot start in CentOS

Joined on 2011-05-17

Hi, I try to run ObjectDB from Linux, but failed. My command is:

java -cp objectdb.jar com.objectdb.Server start

The result is attached.

After typing the command, the system seems halting.

Actually your attached screenshot shows that the server has been started successfully.

If you want to start it in the background, try:

java -cp objectdb.jar com.objectdb.Server start &

Really? My client get no response from that server.

Maybe the firewall shunt all connections? I will try tomorrow.

The server seems connected, but I set my pc ip to the objectdb.conf, and get the following:

Persist failed: Login Error (unauthorized IP address for user 'admin')

Try to remove the ip attribute in the configuration.

The exception that you got might indicate an internal ObjectDB schema validation problem.

I'm running the JPAB bench. The objectdb.conf (<MyWindows>\<jpabpath>\jpa\ObjectDB\objectdb.conf) and the objectdb.conf (<MyServer>/$objectdb/objectdb.conf) are both working, aren't they?

When I modified the former, I get:

Hi, I have not connected a server yet.

Would you please give me a setting for client?

My server setting is:

<!-- ObjectDB Configuration -->

No need to change the configuration.

See the manual for details on connecting to a server from the client.

Hi, I believe the configuration has to been modified or it get this message:

It seems the hyphen does not work.

<users>
                <user username="admin" password="admin" ip="10.63.0.235-10.63.0.241,127.0.0.1" admin="true">
                        <dir path="/" permissions="access,modify,create,delete" />
                </user>
                <user username="$default" password="$$$###">
                        <dir path="/$user/" permissions="access,modify,create,delete">
                                <quota directories="5" files="20" disk-space="5mb" />
                        </dir>
                </user>
                <user username="user1" password="user1" />
        </users>

I have to use identified ip as ip="10.63.0.235,127.0.0.1" or it will be failed.

The ip attribute is optional so you can simply remove it.

This attribute is not included anymore in the default configuration (in version 2.2.8).
