ORA-01264, ORA-19800 Permission denied

Error Description:
----------------------------------
Whenever you try to use Oracle Managed file systems while creating any objects like in this case tablespace it fails with error ORA-01264, ORA-19800 Permission denied. On Solaris the test is,
SQL> create tablespace tbs16k blocksize 16K;
create tablespace tbs16k blocksize 16K
*
ERROR at line 1:
ORA-01264: Unable to create datafile file name
ORA-19800: Unable to initialize Oracle Managed Destination
Solaris-AMD64 Error: 13: Permission denied

Or in linux the error stuck is,

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01264: Unable to create logfile file name
ORA-19800: Unable to initialize Oracle Managed Destination
Linux Error: 13: Permission denied

Cause of The problem:
-------------------------------------
The user don't have the permission to write in the specified location. This is Operating system permission.

Solution of The problem:
----------------------------------
Give the necessary permission to the user so that OS user who is running oracle can create file in the specified directory.
First Scenario:
------------------------------------------
In the first case, it is db_create_file_dest destination where create tablespace will try to create datafile.
We can see the location of db_create_file_dest by
SQL> show parameter db_create_file_dest

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_create_file_dest string /oradata2/shaik
So , now change permission of /oradata2/shaik to 777 or change the ownership.

Log on as root and chnage ownership by following.
-bash-3.00$ su
Password:
# chown -R oracle /backup1
# -bash-3.00$ logout

Now try to create tablespace and hopefully it will work fine.

Second Scenario:
--------------------------------
In the second scenario user don't have permission on flash recovery area.
You can see flash recovery area location by,
SQL> show parameter db_recovery

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /oracle
Now either change permission(chmod 777) or change ownership of the specified location by,
-bash-3.00$ su
Password:
# chown -R oracle /oracle
# -bash-3.00$ logout

Now try to do operation and hopefully it will work.

ORA-00923: FROM keyword not found where expected

Problem Symptom While performing a simple select statement it fails with error ORA-00923: FROM keyword not found where expected like below. SQL> select 48*1024*1024*1024 decimal from dual; select 48*1024*1024*1024 decimal from dual * ERROR at line 1: ORA-00923: FROM keyword not found where expected Cause of the problem The ORA-00923 can be caused by two different reasons. 1)Oracle itself expect FROM keyword in the position but it could not find any. Like below, SQL> select 48*1024 om dual; select 48*1024 om dual * ERROR at line 1: ORA-00923: FROM keyword not found where expected As no from keyword found so error arises. Oracle expected from in place of keyword dual. 2)The secong cause can sometimes mislead you. Like in case of SQL> select 48*1024*1024*1024 decimal from dual; select 48*1024*1024*1024 decimal from dual * ERROR at line 1: ORA-00923: FROM keyword not found where exp

How to make partitioning in Oracle more Quickly

As the table size grows and full table scans happens more frequently then there is no alternative than partitioning in oracle. Partition greatly enhance performance of a query. I will start my partitioning system simply with an example. In my database the following query took 30~35 seconds to complete. After partitioning the performance increased amazingly and it then took only 1 second. My query was, SELECT DISTINCT fs.type, fs.id , fs.pid, fs.cid , fs.cr_id, fs.created_date FROM summary fs where fs.id in (select fa.id from forms fa where fa.sar in (select la.sar from login la where la.login_id=1 and fa.created_date BETWEEN to_date('1-MAY-2008') AND to_date('21-SEP-2008') and fs.created_date BETWEEN to_date('1-MAY-2008') AND to_date('21-SEP-2008') ) )and mode=0; After seeing above query I decide to make range partition on column created_date both in summary table and forms table. Below is the list of procedur

Copy files between Unix and Windows with rcp

There are many third party tools by which you can copy files between windows and unix machine. Some common tools are winscp, SSHSecureShellClient etc. Instead of using any third party tool, you can use original unix and windows built-in tool to do the task. The RCP (Remote CoPy) is a standard UNIX tool and a Microsoft Windows 2000 tool that copies files/folder to and from computer running the RCP service. Before you can use the RCP tool from a Windows-based computer you must do something in your UNIX computer. you must turn on the RCP service and update the security files to allow the Windows-based computer to connect to your unix machine over this service. The following steps will help you. Step 01: Turn on RCP service on UNIX Host Turn on the RCP service on unix machine by using inetd: 1. Log on as root. 2. Edit the file /etc/Inetd.conf. 3. Uncomment the lines that start with shell and that start with exec. 4. Save the file. 5. Use ps -ef |grep inetd and determine inetd service p
