Now its working fine. Oracle Standard, not Enterprise and Charset WE8MSWIN1252. But when i'm trying to protect the main page i'm getting this error:

A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: https://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script

ORA-01400 issue was fixed in gerrit 16810.

The actual problem reported by this bug was obviously a problem with DB, not MW software, so i'm closing this bug.

I'm guessing you tried re-running a failed installation without clearing the old state.

tables.sql has two insert statements that create user_id=0 user and revision_id=0 revision, to prevent that FK violations. You can check to see if that row exists in users and revisions table.

My advice would be to drop the user you're trying to create during installation and run the installer again.

t.i.ivanov wrote:

I do drop the user before every installation:

drop user "WIKIUSER" CASCADE;

create user wikiuser identified by SOMEPASSHERE default tablespace users temporary tablespace temp quota unlimited on users;

grant connect, resource to wikiuser;
grant alter session to wikiuser;
grant ctxapp to wikiuser;
grant execute on ctx_ddl to wikiuser;
grant create view to wikiuser;
grant create synonym to wikiuser;
grant create table to wikiuser;
grant create sequence to wikiuser;
grant create trigger to wikiuser;

Here I have screenshotted my install steps:

Thanks for the help in advance.

Weird, i've just tried 1.21.1 and 1.22alpha on 11gR2 with the same procedure you tried and it works as expected.

Can you try after a failed install manually inserting that dummy user (it's in maintenance/oracle/tables.sql on line 29).

t.i.ivanov wrote:

I hope I understood you correctly:

oracle@main-server:~$ sqlplus wikiuser/SOMEPASSHERE

INSERT INTO mwmwuser VALUES (user_user_id_seq.nextval,'Anonymous',NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL, '', current_timestamp, current_timestamp, 0)

If I did something wrong, please let me know.

Ok this is getting weirder. Installer complains that the dummy mwuser is missing, but it exists.

Could you check if you happen to have case-sensitive login enabled?

t.i.ivanov wrote:

SQL> SHOW PARAMETER SEC_CASE_SENSITIVE_LOGON;

NAME TYPE VALUE

sec_case_sensitive_logon boolean TRUE

I will disable it and try again the install.

No difference :(

freak wrote:

no don't try to insert ... do as you did before: drop wikiuser (check if there are others like "WIKIUSER" and drop those too) and retry the installation.

t.i.ivanov wrote:

Actually the result above is from the following sequence:

1. I made sure sec_case_sensitive_logon is FALSE (also restarted DB just in case as it said it may take a while)
2. Dropped and recreated the user as per my post #9
3. Made the installation as per the PDF file in #9
4. Run manually the INSERT statement from your #10 again to see if something changed.

I am really out of ideas. Could it be something oci8 or PHP (5.3.3-1ubuntu9.10) related?

There are no other wiki like users. I made ULTRAWIKI database entirely for this installation. I completely erased the mediawiki folder from my apache to make sure, there is no caching from older install attempts.
I can create another DB for the test install, if you think there might be something wrong with the current.

freak wrote:

Have you tried dropping the user and creating it trough the installer?

Enter SYSTEM and it's password, uncheck "Use same account..." and enter wikiuser and pass in the second set of fields and check "Create if missing..."?

I'm just fireing blind here ... i just can't seem to reproduce the error on my setups. I don't have 11gR1 anywhere (i have 10gR2 and 11gR2).

t.i.ivanov wrote:

1. Dropped the user manually
2. Unchecked: Use the same account as for installation
3. Entered

Database username: wikiuser
Database password: some pass here

4. Checked: Create the account if it does not already exist

Now the results fails here:

Install

Setting up database... done
Creating database user... failed

DB connection error.

Check the host, username and password and try again.

One small note:

The web installer would not start until I commented out lines 90 and 91 here:
includes/installer/OracleInstaller.php

I saw it in this post:
http://dolicapax.org/?p=152#comment-420

I pass the database in the web installer as localhost/ultrawiki

About lines 90 and 91 in the installer:

EZconnect fix hasn't been backported yet, well it was, but the change hasn't been merged with 1.21.

freak wrote:

We (me + Todor) found the issue, bug i still can't figure out the cause.

For some reason user_user_id_seq skipps the first value (0).

I'm attaching a patch for maintenance/oracle/tables.sql file and will try to put it in repo asap.

Thank you very much, Jure!

The installer now completed successfully. I will test in the next two days the other functionalities.

Jure: Should this ticket be reopened for the patch in comment 22? Is there a related Gerrit change?

freak wrote:

You've got a point ... reopening until this patch gets put into the code, so it can be tracked.

No Gerrit change exists yet for this patch.
