drop and re-create the tablespace

version 9208
the requirement must deletes and recreates same tablespace with different data file location, could it cause any problem?

Published by: DBA2008 on February 18, 2010 15:24

The problem is that you lose data, which is currently this tablespace (unless export you it before).

Detaching Frank, however, and echoing my previous comment, let them down and to re-create the tables makes no sense. It is logical to truncate a table if you test a load. If you build a data warehouse, it makes sense to delete and re-create a partition if you rerun a load for a particular date and that you have daily partitions. Deletion and recreation of a table in a stored procedure is not a reasonable way to test a system (nor is there a reasonable way to approach change control issues that will inevitably produce when you need to change the structure of a table).

Drop and re-create the index on the current table
Hello

I just have a few questions about the removal and creating indexes on a table that activates a lot.

Let me explain first:

The table is used by the application with the DML statements every 3 seconds and I want to do is to drop the indexes and re-create them.
But Im worried about the consequences - what happens when I try to recreate the indexes and the table has an option rowlock/used by the application?

P.S
It's production environment - so I can't stop the application.

A reconstructed index either Online or Offline.

Online index rebuild features:

ALTER INDEX REBUILD ONLINE;

LMD is allowed on the base table
It's relatively slow
Base table is targeted for the new index
Base table is locked in shared mode and DOF is not possible
Intermediate table stores changes to data in the base table, during the rebuilding of indexes to update the new index later

Offline index rebuild features:

ALTER INDEX REBUILD. (Default)
Does not refer to the base of the table and the base table is exclusively locked
New index is created from the old index
Not possible DML and DDL on the base table
Relatively faster

drop and re-create the table
Hello

I am very new to the Apex. Very basic SQL and pl sql.

Two questions: -.

First of all, I want to delete a table and then recreate the same table in a script (strange I know but it is purely a LOV table).

Then, run the combined script when a user presses a button on a form in the published application.

REPORTED
Hi reported.

The delay I was referring to that is that when you go on a database connection, it takes much longer for a long time as if it were local. Rather than create a local table, why don't you just make the LOV created through data binding? for example the LOV queries:
```
SELECT DISTINCT surname display_value, surname return_value
FROM CUSTOMER_TBL@DBLINK
```

What consideration we should have have before creating the tablespace
Hello
I was asked this question in an interview. I have a large volume of data (for example 80 GB). Now, I have to create a tablespace to contain these data. What consideration we should have have before creating the tablespace.
In fact, I could not answer after a lot of research, so I post here.

Concerning
Hello

In 10g, you must create a locally managed Tablespace (MEASURE of the LOCAL MANAGEMENT) If you know the
size of your Tables/indexes you can choose the size of the scale with the option of UNIFORM SIZE.
If you have small and large Tables / Index, then choose the AUTOALLOCATE option.

It is recommended to use SAMS with the SEGMENT SPACE MANAGEMENT AUTO option and then the PCTUSED
is auto tune by an internal algorithm and FREELIST are managed by a bitmap. With this option, it is best to
be with the last group of hotfixes.

About BIGFILE Tablespace, if you use BIGFILE tablespace, you will have just a data file which can extend up to
4G block (thus 32 TB if you have db_block_size = 8KB). And SQL syntax allow you to manage the 'big' with data file
the same command for the Tablespace.

But you should care the limit of your OS. Imagine that your operating system or the file system does not support very largefiles then,
you have no advantage over the use of Bigfile tablespace. Also, you might have more than 1 data file.

Smallfile Tablespace using your data files should not exceed 4M block (so 32 GB for 8 KB / block) but you can have
up to 1022 datafiles on your Tablespace. So eventually, if you use the 1022 data files, you have the same capacity
Bigfile Tablespace and you can use several system files.

To 80 GB with 3 or 4 data files, you can easily manage this volume. But of course from time to time you will have to
Add a new data file.

Hope this can help.

How to monitor connections dropped and rejected on the PIX Firewall / ASA?

I need to monitor the SNMP OID of the connections dropped and rejected on the PIX and ASA firewalls. Is this possible?

If this is the case, what SNMP OID should I monitor?

Syslogs and Netflow (introduced in version 8.2) are your options.

By program (step by step) read data XFDF and dynamically create the form

Hej,
I have a form created dynamically with JavaScript in Adobe Acrobat 9. I exported the variable amount of data in an XFDF file.
Now, I want to import the XFDF file into a second PDF file. But while the data is variable, I need to read the data imported manually
and to create the new PDF dynamically. This is required, while the new PDF must contain a chart made in Flash and will be
filled with data from the XFDF file.
My problem is, that "doc.importAnXFDF ()" does not return the data that is imported as an object. I was looking for solutions
but I have always found solutions to automatically populate an existing form. The API guide is not useful. Where can I read the imported data
to iterate on and in the process.
Thank you very much.

As I discovered (https://acrobatusers.com/tutorials/extracting-pages-pdf-acrobat-javascript) it is possible to save a range of

pages programmatically. In fact, this has many advantages for my use case, including to prevent the many errors made by users.

So I decided to use this solution and close this issue.

Question about AUTOALLOCATE and UNIFORM in the tablespace management
Good afternoon

I'm unclear as to if a UNIFORM extent allocation means that the data file must be manually extended or not.

Documentation:

>
The following statement creates a managed tablespace locally named lmtbsb and specifies AUTOALLOCATE:
Lmtbsb CREATE TABLESPACE DATAFILE ' / u02/oracle/data/lmtbsb01.dbf' SIZE 50 M
EXTENT MANAGEMENT LOCAL AUTOALLOCATE;

AUTOALLOCATE causes tablespace system managed with a volume of minimum extent of 64K.

The alternative to AUTOALLOCATE is UNIFORM. who says that the tablespace is managed with uniform size extents. You can specify the size of the uniform SIZE clause. If you omit the SIZE, the default size is 1 M.

The following example creates a tablespace with uniform extents of 128 K. (In a database with 2 K blocks, each would amount to 64 blocks of data). Each measure 128K is represented by a bit in the bitmap extent for this file.
Lmtbsb CREATE TABLESPACE DATAFILE ' / u02/oracle/data/lmtbsb01.dbf' SIZE 50 M
EXTENT MANAGEMENT UNIFORM LOCAL 128K SIZE;
>

It is clear that the clause UNIFORM control the size of the scope which will be awarded, but doesn't really say if these will be assigned manually or automatically. In other words, I'm not clear as to whether or not the data in the second case file will be automatically extended.

In my test environment, when I published the command:
```
SQL> create tablespace largetabs datafile 'E:\Oracle\app\Private\oradata\dbca\largetabs.dbf' size 100M extent management local uniform size 16M;
```
and only looked into the tablespace EM I had created above, there is no check mark in the box "Automatically extend datafile when full", which led to the doubt that I have now.

Is: during the extended allocation is UNIFORM, this means that space must be allocated manually or can the renewed automatically datafile? If it can be automatically extended, I would appreciate an example of a create tablespace command that allows to achieve this result.

Thank you for your help,

John.

There is nothing relationship extended datafile and management extend way (autolallocate or manually-uniform). See below

Create the work around plan group, unless there is a clipping path, and then create the work around clipping path plan

Hello again everyone.
I was able to work on a lot of this code to other people's questions, but I hit a snag in my if/else clause structure... I need to make a plan to work around each groupItem of high-level layer [0]. This part is cake... unless there is a clipping mask. Visible limits do not work when there is a clipping mask. So, I built some of the loops that browse the pathItems search the clipping mask and return the visibleBounds said mask. However, I can't find how to structure the if clause in a way that will create the plan of work around the clipping mask when one exists.
I am successful to find the visibleBounds of the mask and the creation of the appropriate graphic board, but it is ALSO to create a work plan around the visible boundaries of the entire group. How framing an if clause to determine if a work plan has been done around the clip path already and therefore not create a second work plan around the visible boundaries of the groupItem together? I guess I would need some sort of function to determine if createdArtboardAroundClip = true and if so, skip this group...
Thank you all.
Here is the code:
```
var aB = docRef.artboards;
var docLayers = docRef.layers;
var layer1 = docLayers[0];
var groupLevel1 = layer1.groupItems;

for (a = 0; a < groupLevel1.length; a++){
    var groupLevel2 = groupLevel1[a].groupItems;
    var vB = groupLevel1[a].visibleBounds
    
    for (b = 0; b < groupLevel2.length; b++){
        var paths = groupLevel2[b].pathItems;
        
        for (c = 0; c < paths.length; c++){
            if (paths[c].clipping == true){
                var clipBounds = paths[c].visibleBounds;
                aB.add(clipBounds);
                break;
                }
            }
        }
    aB.add(vB);
    }
```
Oh sorry, I forgot that one. I was able to view the image basically to see what is happening. Okay, so I saw a problem, you have one of your straps closure irrelevant. Your first nested for loop does not close where you want.

Wireless connection drops and reconnects to the games only?

I have an Asus ea - No. 66, WIndows 7 64 bit, whenever I connect to a game, being especially csGO. I lose the connection and gain back almost instantly. I'm not connected to the game or anything else. Then everything comes back online. I was wondering, which could materialize this project?

Hi boozal,.

Thanks for posting that query you in Microsoft Communities. Provide the following information:

· Did you do changes on the computer before the show?

· You get the error message?

Follow these methods.

Method 1: Temporarily disable the security software .

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

Method 2: Follow these steps:

Step 1: Start the computer in safe mode with network and check if the problem persists.

Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

Note: After completing the steps in the clean boot troubleshooting, follow step 3 from the link to start the computer to a Normal startupmode.

DROP AND RE-CREATE ALL INDEXES
Hi all

I have a database with all the struture of tables and their indexes, but no data on the tables.

I have scripts to import that will insert millions of rows in tables.

What I want to do is:

(1) built a sript which creates all indexes
(2) remove all indexes
(3) load all the data in the tables
(4) create all indexes the sript running 1)

My problem is on point 1). I don't know how to build this script.

Thanks in advance for any help,

RS
Yes, I see that I go wrong here... once again ;-)

I have also addressed this issue in the past and now, remember that there are also some Metalink Notes on this topic, where people complain about the same problem.
Especially Note 394143.1 manages your problem
I'm sorry for the mistake. Maybe this note helps.

I went to the #3 option.

Edit:
In fact, it is the script to generate the DDL and put them in a CLOB table. In this case for Materialized views:

Set serveroutput on;
declare
CLOB ddl_out;
objname varchar2 (30): = ";
tablechk varchar2 (100): = ";
number of sqlorder: = 1;
cursor c1 is select a.mview_name, a.owner from dba_mviews; -where owner = 'EHDA ";

Start
-Due to formatting problems dbms_metadata, the output is saved in a table that contains a clob column
run immediately "drop table ddl_output;
immediate ' create table ddl_output (objname varchar2 (30), ddl_query clob, number sqlorder);

for r1 in c1
loop
dbms_output. Enable (10000);
If objname = r1.mview_name
then
dbms_output.put_line (' treatment: ' |) R1.mview_name);
on the other
objname: = r1.mview_name;
sqlorder: = 1;
end if;
insert into ddl_output values (r1.mview_name, 'drop the materialized view' |) R1.mview_name | ';', sqlorder);
sqlorder: = sqlorder + 1;
Select dbms_metadata.get_ddl ('MATERIALIZED_VIEW', "|) R1.mview_name: ",". R1.owner | ") in the double ddl_out;
insert into ddl_output values (r1.mview_name, ddl_out |) ';', sqlorder);
sqlorder: = sqlorder + 1; Select dbms_metadata.get_dependent_ddl ('INDEX', "|) R1.mview_name: ",". R1.owner | ") in the double ddl_out;
insert into ddl_output values (r1.mview_name, ddl_out |) ';', sqlorder);
sqlorder: = sqlorder + 1;
commit;
end loop;
end;
/

After that which has finished, use the script below to recreate the object with the table DDL

declare
query varchar2 (2000);
cursor c1 is select ddl_query from ddl_output by objname, sqlorder;

BEGIN
for r1 in c1
loop
dbms_output. Enable (999999);
query: = r1.ddl_query;
dbms_output.new_line ();
dbms_output.put_line (Query);
If length (query) > 5
then
immediate execution of the query;
end if;

end loop;
end;

Events and Reminnders created the iPhone sync on iPad

Hello

I have a weird problem. If I create events or reminders on my iPhone, they don't appear on my iPad, unless I have add an adverse event or a reminder on the iPad, then only my iPad syncs.

If I create an event or a reminder on my iPad, it immediately appears on my iPhone.

So I don't know what is happening?

You have background refresh enabled App on your iPad? Settings > general > App Background Refresh?

Drop-down list creates the checklist

I would like to create a material withdrawal form when a user selects a piece of equipment, it will list all the elements that are included in this piece of equipment so that the user can check every point to ensure that everything is there. The elements would be checked once the form is printed, so they must be completed online. Is this possible? If so, how? Be nice, I am a newbie.

You can go there. The code is on the event of the DropDownList control output. Let me know what you think.
