[otrs] Try to restore OTRS

[Adi Ariyanto]

First of all thank you for anyone that answer my question J

After I try run backup otrs on my otrs virtual machine, now I want to try to restore it, i got an error

 “ERROR: Already existing tables in this database. A empty database is required for restore!”

Information

1.  I am used my copy of OTRS vmware, it’s very fresh, just need run /installer.pl to setup

My question is 

1.  It’s a fresh system, I even not yet create a ticket, just test that /index.pl is opened, but why I got an error about existing tables? How to make this restore test is work ?

Thank you

What backup tool did you use? the backup script that comes with otrs should create the correct commands...

Your  SQL dump probably contains CREATE TABLE directives without DROP TABLE, which doesn't work if the tables already exist. You could either load the SQL file (shouldn't be too big if you did not create any tickets yet), search for all

CREATE TABLE `tablename`

directives and put

DROP TABLE IF EXISTS `tablename`;

above them. You could also simply use

DROP DATABASE databasename;

and

CREATE DATABASE databasename;

(all from the mysql command shell) to create an empry database

but this is only recommended if your SQL dump includes the neccesary information about collation, character set etc.

Both I am use OTRS backup and restore tools

I am backup with this command /opt/otrs/scripts#./backup.pl –d /var/backup_otrs à I put the backup folder in /var/backup_otrs, and success

Then I try to restore to another otrs machine with this command

/opt/otrs/scripts# ./restore.pl –b /var/backup_otrs/2012-07-25_11-45 –d /opt/otrs

Hi ,

I run otrs.PostMasterMailbox.pl in crontab every 5 minutes. If there are 50 mails in mailbox, the OTRS parameter PostMasterReconnectMessage is set to 10 , does it mean that otrs.PostMasterMailbox.pl will reconnect POP3 server after fetches 10 mails to  get other mails ? or will it stops after fetches 10 mails and connects POP3 server in next 5 minutes of cron jobs? 
Thanks!

Justin

Well, did you check the database on the target machine? Does it contain tables? If so, delete them. As explained, the backup SQL should take care of this, but... also check if there are sufficient rights to write to the database and alter / drop tables for the database user.

What I have done is like this..

 

In terminal I am logon to mysql

Mysql –u root –p

Then I am DROP DATABASE otrs and CREATE DATABASE otrs then try to restore again, no error, the ticket is also restore, I don’t know if my way is safe or not..

 

But for your information

In my new linux machine I am just install apache, mysql and other dependency to install OTRS, but I am not yet run /otrs/installer.pl, I think in this condition the database just contain basic mysql database, because otrs database not yet created.

It will reconnect every 10 messages until it has pulled them all.

I tracked the log of executing "otrs.PostMasterMailbox.pl -d 2 " , found that the script get 10 mails, then the script stops and until the next time cron job starts ,the script otrs.PostMasterMailbox.pl begin to receive next mails. 

POP3: Reconnect Session after 3 messages...

POP3: Connection to 192.168.10.18 closed.

Is this a bug ?

I am using OTRS 3.0.8 .

Thanks

[Steven Carr]

Well I'd advise upgrading to the latest version for your release (3.0.13) and then see if you still have the same issue, if you do then check http://bugs.otrs.org to see if it's logged.

I'm trying to figure out why this matters, exactly. If you know the limitations, increase the batch size, especially if you expect > batch size number of tickets per fetch. On the other hand, if you expect 1000 tickets per fetch, and you're fetching every minute, that doesn't seem healthy. You should consider changing to procmail to handle the tickets immediately as they arrive.
