Script to Collect Database Information Quickly

Jan 23, 2014 / By Hemantgiri Goswami

Tags: , , , ,

As a DBA there are occasions where we are required to collect details from a database which can 
be used for further analysis. For example, getting the status of the database (i.e. File Size, 
Free Space, Status of the database, and who is the current owner of the database). This kind of 
information is required, and very useful, for auditing purposes in addition to tracking the database/database 
file's size for various reasons. I had a script which does this job for me, exactly the way 
I want it; however, I have to run it for each database separately.  

One fine day, while answering some question's on a forum, I found a script by Dan Guzman which 
retrieved most of the information I needed, and it does this for all the databases. I have 
adopted Dan G.'s script for my use and modified it by adding some more details to it. 

Please review the script below. Let me know if you like it or dislike it. I will try to 
make further improvements on this script.

    Hi Hemant,

    Nice script. Just one quick comment. The “CREATE TABLE” statement references MB for some of the table names while the “INSERT TABLE” statement references GB. I’m pretty sure you meant GB and based on my results I was able to validate that. Also, you may want to augment the script with one column for the actual percentage of free space left. Good job on the script though!!!

  • hmm , works but that looks more like something from 2000 days with sysaltfiles and database status code.

    sys.master_files can retrieve info about files under databases that are not online because it’s stored under master database so will get full picture of your databases.

    Cheers

    • Hi Mohammed,

      Yes, this script was created for a client who had most of the servers on 2000 :). I am in progress of making a new version of this script that will include the VLF count as well. I will try to make change accordingly to use sys_master_file

  • Samir Saad says:

    I am getting SP2-0310: unable to open file “SqlStatement.sql”
    i.e it does like those @@ signs. what are they for ? and how to get the script to run ?

  • ajay says:

    Excellent script, the one i’m looking for, I tried running the script without any modification but getting some messages, please see the details given below –

    Cannot resolve the collation conflict between “Latin1_General_CI_AS” and “SQL_Latin1_General_CP1_CI_AS” in the equal to operation.

    Given below is the line that is causing error

    ,[FREE_SPACE_GB] = (CONVERT(decimal(12,2),round((f.size-fileproperty(f.name,”SpaceUsed”))/128.000,2))/1024)

    Could you please elaborate more on this error please?

    Hi all

    Please can anyone help me with add the details below to this Script i have run it on my test system and it’s works fine

    I am required to collect full details from all of our oracle database/server to be used for analysis.

    Many Thanks

    RDMS
    EDITION
    HOST NAME
    IP ADDRESS
    NO OF INSTANCES
    SERVER
    DATABASE NAME or SID

    Hi Yunis,

    Probably it would be better to ask these questions in an Oracle based forum, rather than a blog about SQL Server,
    as you are more likely to get useful responses that way.

    Fortunately at Pythian we have lots of folks working on various database technologies :)

    Your request is somewhat short on details, so the following may or may not fit your needs.

    For instance, will you be logging on to the server to get this info?
    If so, you already know the hostname.

    The following connections use elevated privileges.
    If you have access to the server then you will be able to run these commands.
    If not then you will need to connect remotely to the database

    Connect to the database as a user with privileges that allow reading the data dictionary
    The SYSTEM account will work for this.

    RDMS
    EDITION
    col product format a40
    col version format a30
    col status format a30
    set linesize 120 trimspool on
    select * from product_component_version;

    HOST NAME
    This query will provide the database server name
    select sys_context(‘userenv’,’server_host’) from dual;

    If using RAC, probably just get it from gv$instance
    select i.inst_id,i.instance_name from gv$instance i

    This information is also available from the command line in Windows/Linux/Unix
    >$ hostname
    someserver

    IP ADDRESS
    Replace the hostname parameter with the value returned by the previous query
    select utl_inaddr.get_host_address(‘HOSTNAME goes here’) from dual

    This information is also available from the command line in Windows/Linux/Unix

    Windows:
    ipconfig /all

    Linux/Unix:

    ifconfig -a
    or
    ip a

    NO OF INSTANCES

    You haven’t specified just what you are asking for here.
    The number of instances on the server?
    If so then there several ways to go about it, here are a couple.

    Windows:

    sc queryex type= service state= all | find /i “Ora

    Linux/Unix:

    Find the oratab file.
    Usually it is in one of two places

    /etc/oratab/
    /var/opt/oracle/oratab

    This command will show all the oracle homes that are listed in oratab.
    These may or may not correspond to the actual number of instances running on the server.

    grep -vE ‘^#|^$’ /etc/oratab | cut -f1 -d:

    Another method:

    ps -flea | grep [p]mon

    SERVER
    Sorry, don’t know what you are asking for here.

    DATABASE NAME or SID
    Database and SID are two separate things.
    On standalone databases they are likely the same value.
    For RAC databases they will be different.

    The SID will be the values seen in the oratab file.

    Database name:

    select name from v$database;
