What is the default quota on a tablespace for a given user in oracle if you do not set it?

My environment

j & # 39; uses Oracle Database 12c Enterprise Edition Release - 64bit Production

Explanation of the situation

I created a user with the following command

create user USRPRACTICA2 identified by 1234 default tablespace users;

So, I gave it a default tablespace, but I did not specify any quota limits. So I went to the Oracle documentation, and I read this:

By default, a user has no quota on the tablespaces in the database. If the user has the privilege of creating a schema object, you must assign a quota to allow him to create objects. Minimize the quota for the default table space and additional quotas for other tablespaces where they can create objects.

So I said good, okay! Now, I want to test if this user really can not create tables, for example, if I have not assigned a quota.
Then I granted him these privileges:

grant create session to USRPRACTICA2;
grant create table to USRPRACTICA2; 

Well, I should not be able to create tables because I did not specify a quota for tablespace users. Let's try.
I'm creating a connection with USRPRACTICA2 to Oracle, I'm trying to create a table and here's what happens:

  3  ENAME VARCHAR2(10),
  4  JOB VARCHAR2(9),
  5  MGR NUMBER(4),
  7  SAL NUMBER(7, 2),
  8  COMM NUMBER(7, 2),

Tabla creada.

Oops! The table has been created.

Right now, it's when I think "well, now we should try to figure out what the quota is for this user on this tablespace, maybe there's a default quota in oracle". So I tried this:

SQL> select tablespace_name, username, max_bytes
  2     from dba_ts_quotas
  3     where username = 'USRPRACTICA2' and TABLESPACE_NAME = 'USERS';

no rows selected

At this point, I thought that "it's nonsense, maybe I did not write the query properly", so I tried this:

SQL> select * from dba_ts_quotas;

TABLESPACE_NAME                USERNAME                                                                                                                      BYTES  MAX_BYTES     BLOCKS MAX_BLO

6 rows selected.

So with this information, I assumed that, of course, no quota was allocated to the users' table space for the user I had created.
In addition, I assumed that in Oracle, it should contain a value with the default quota on tablespaces, if you do not set it. Moreover, this user does not have unlimited space on the tablespace either, because it would have appeared in this view with a value "MAX_BYTES -1".

I've gone through a lot of things looking for a default quota value in Oracle, and all I've been able to get, is an oracle extract saying "If the user has the privilege to create a schema object, you must assign him a quota to allow him to create objects." . But obviously, as I showed here, this should be a default quota value somewhere.

Finally, I just tried something else. If you assign a quota value to the user like this

alter user USRPRACTICA2 quota 1M on USERS; 

Now, if you query the tablespace quotas, you will find the information

SQL> select tablespace_name, username, max_bytes
  2     from dba_ts_quotas
  3     where username = 'USRPRACTICA2' and TABLESPACE_NAME = 'USERS';

So my question is this …

Is there a default quota value assigned to a user in a tablespace if you do not specify it? If so, how can I show this value?

Set the new theme setting on the default theme update


  1. We have a basic custom theme.
  2. There are custom theme settings with default values.
  3. When the theme is initially installed, its settings are correctly set as the default settings. Good.
  4. This basic custom theme is now available on our many live sites.

Does not work

  1. We've added a new custom theme setting to the base theme and set a default value.
  2. When we update the base theme on a site, the new theme setting is present. Good.
  3. However, the default value is not populated.

How to set the default value of a new theme setting when the theme is updated?

python – Management of user-defined and default values ​​for instance attributes

What follows works as expected but I wonder if there is a more idiomatic way to check the entry kwargs compared to the arguments required by the user (not by default).

It is written like this: in order to continue developing and modifying my script and adding attributes, I just need to add them to the class variable defaults = {'A':None, 'B':0, 'C':0} and put it to None if the user must specify it. I also like that managing this as a class variable is visible at this time.

I've included a modified adaptation of point 6 in this excellent answer which guarantees that all arguments end as float or np.arrays with the same length.

In this example, a value for A is required of the user. They can enter values ​​for B and C but otherwise, these are initialized to 0.0. Any additional argument such as D=42 will simply be ignored.

import numpy as np

class O(object):
    defaults = {'A':None, 'B':0, 'C':0}
    required = (key for (key, value) in defaults.items() if value == None)
    ok       = False

    def __init__(self, **kwargs):
        if not all((key in kwargs for key in self.required)):
            print('problem, something required is missing')
        setup = self.defaults.copy()
        for (key, value) in kwargs.items():
            if key in setup:
                setup(key) = kwargs(key)  # user specified overrides default
        setup = self.fixem(setup)
        if setup:
            for (key, value) in setup.items():
                setattr(self, key, value)
            self.ok = True
            print('something did not work')

    def fixem(self, setup):
        # adapted from https://codereview.stackexchange.com/a/233169/145009
        results        = None
        keys, values   = zip(*setup.items())
        arrays         = list(map(np.atleast_1d, values))
        sizes_ok       = len(set(map(np.size, arrays)).difference(set((1,)))) <= 1
        all_1d         = set(map(np.ndim, arrays)) == set((1,))
        all_good_types = all(array.dtype in (np.int64, np.float64) for array in arrays)
        if all((sizes_ok, all_1d, all_good_types)):
            arrays = (array.astype(float) for array in arrays)  # make all arrays np.float64
            values = list(map(lambda x: float(x) if len(x) == 1 else x, arrays)) # downcast length=1 arrays to float  
            results = dict(zip(keys, values))
        return results

8 – Change the language code for the default language

I have a multilingual website with English as the default language.

The language code for English is currently en but I want to convert it to en-US.

I have considered adding a new language with the correct language code, but I do not think this is the best solution because I have a lot of translated content, and I do not want to add all the translations again for the new language.

Is it possible to update the language code of a current language, if not, what can I do?

I have several languages ​​on my site and I want to update all their language codes without losing my translations.

Create an array with default headers in an enhanced rich text column

I have a custom list and would like to have a field with a table with three headers.

I already have a field and I can insert a table, but I have to do it manually every time. Here is the field:

Multiline text field

The behavior I would like is that when I select +new item the column would create the table and headers as a kind of "default" – would create a 4-line table with headers.

Table image with headers

I've already tried this suggestion from C # Corner – I went into Designer and I changed some settings, but that did not allow me to get what I was looking for:

enter the description of the image here

Ideally, this could be done without having to resort to a workflow, which would trigger when creating items, but if I had to, I would do it that way.

Thank you for your suggestions

Apache2 Ubuntu Default Page displayed after the reinstallation of apache

Ok, here's what I had to do to make it work:

in enabled sites, no symbolic link to available sites (where all "virtual servers" have been configured)
to create symbolic links:
a2ensite domain.com

but I quickly encountered this problem:
apache2 reload service
* Reloading the apache2 web server *
* Configtest apache2 failed. Do nothing.
The output of the configuration test was:
(Thu 28 Nov. 17: 11: 41.546493 2019) (thus: warn) (pid 6454: tid 140699176986496) AH01574: the module rewrite_module is already loaded, jumping

comment on the following two lines:

sudo service apache2 restart

Clear your browser cache (Ctrl + Shift + Del)

My sites started working when I configured them on apache mod_php, not on fcgid

so i had a2ensite everyvirtualserverdomainonmyserver.com

and I was back in business :)
