Using oracle 11.2.0.3...How long does the content in recycle bin stay?
e.g is it dependant on size of undo tablespace and expires after certain time? Also if drop table, then recreate table with same name will this wipe the dropped table from the recycle bin automatically?
I am on 11.2 on Linux.I am looking into a performance issue. The issue is around 1 particular SQL, involving about 5 tables.I re-gathered statistics on 2 main tables in the query (out of 5 tables).
When I say re-gathered, I first did DBMS_STATS.DELETE_TABLE_STATS and then did DBMS_STATS.GATHER_TABLE_STATS.
Earlier, we had histograms on these tables, which I removed and gathered stats without generating histograms.
SQL> select table_name, num_rows, sample_size, last_analyzed from user_tables where
2 table_name in ( 'DETAIL_TABLE','MASTER_TABLE');
TABLE_NAME NUM_ROWS SAMPLE_SIZE LAST_ANALYZED
------------------------------ ---------- ----------- -------------------
MASTER_TABLE 50615338 50615338 01/10/2012 11:09:27
DETAIL_TABLE 353550440 353550440 01/10/2012 11:10:05
2 rows selected.Then ran the SQL again couple of times (actually, that SQL is in a stored procedure, which I ran couple of times).I found this wonderfull SQL on internet, which tells me when the SQL ran and which plan (identified by its hash value) it used. Using this SQL I tried to check if my SQL was run using any different plan, but it used exactly same plan it used before I re-gathered the stats. See the last analyzed time above and begin_interval_time below, same SQL has run before and after stats collection, with same plan_hash_value.
SQL> select ss.snap_id, ss.instance_number node, begin_interval_time, sql_id, plan_hash_value,
2 nvl(executions_delta,0) execs,
3 (elapsed_time_delta/decode(nvl(executions_delta,0),0,1,executions_delta))/1000000 avg_etime,
4 (buffer_gets_delta/decode(nvl(buffer_gets_delta,0),0,1,executions_delta)) avg_lio
5 from DBA_HIST_SQLSTAT S, DBA_HIST_SNAPSHOT SS
[code]....
7 rows selected.
My question is, when I re-gathered stats on 2 tables out of 5 tables in a given SQL, are the plans not flushed out of SGA? I was expecting that, at least a new plan hash value would show up front of my SQL, before and after stats collection.

what's long connection and short connection in Oracle ?
View 4 Replies View RelatedA DB server (Oracle 11g) on Linux will support a Web Application Server (Java based) for hosting a public web site.For sending multiple INSERT statements over from the Java Server to Oracle Server, I have two ways to do it:
1) Wrap those insert statements together and send it over with one connection to Oracle
2) Send each insert statement separately to Oracle. As the result, multiple insert statements are sent and accordingly multiple connections to Oracle are needed.
Advantage of option 1 is just using one Connection. Disadvantages are that Oracle will then need to parse the statement string into multiple separate insert statements, and then loop through them to execute each. This may be costly in CPU sense.
While the option 2 may have quicker execute of each insert statement, but will need to create multiple connections.If the number of users is known and stable (such as intranet), I would prefer option 1; while for the internet there could hundreds concurrent users at the peak, I lean towards the option 2.
a query or function which can be used to see the content of deep down view.
For Example :- create view fist as select * from second;
create view second as select * from third;
create view third as select * from fourth;
....
So my requirement is like dbms_metadata.get_ddl function to see the content of objects? to see the see the content of deep down view..
I wondered the possibility of converting a content file in the format ansi to utf-8 directly from Oracle.

View 6 Replies View RelatedI need to modify the content of all HTML content to be sent as response from our server according to the tag. say for example, only text content inside a td or div tag will be modified. As per solution we have thought the content will be captured in the Filter of the server. Here, we will split the content against tag and modify the desired text, and then merge them again.
So, for example, if my content is,
.....
<tr>
<td valign="center">Claim Event Code </td>
<td><input type="text" class="field" name="EventCode"size="20"></td>
<td valign="center">
<SELECT name="pClaimStatus" >
<option value=""selected></option>
<option value="A">Notified</option>
<option value="B">Opened</option>
.....
then my desired output (may be an array) will be like this --
1. <tr>
2. <td valign="center">
3. Claim Event Code
4. </td>
5. <td>
[code]......
so that now I can work upon item 3, 13, 16 and so on. Is this method is ok? if so how could we split and get such array in java.

So the query needs to prove that Schema A content = Schema B content
I know I cant do a simple select from Schema A.tab1 minus select Schema B.tab1 but since there are 159 tables, I am not sure if this is an efficient way of doing it.

I have a matrix report that shows production per year(horizontal) and per country(vertical). The customer's willing to see the data ordered by production, and not per country. I tried to add a CF containing the production in the country group and order by that one, but I'm getting a message saying that the field object cannot be contained into the frame. Both the field and the containing frame are set to Variable. how to get rid of the error or how to achieve the main goal of ordering by the cell content?
View 11 Replies View RelatedI have just implemented a "Data Load" function which is the OOTB page type in apex 4.2 which allows the end user to go through a wizard and import csv data into a table.
When the user is viewing the data to be imported - they have to scroll across the length of the screen (depending on how many columns you are loading). I noticed there is a Region template called "Scrollable Content Region". I tried applying this template to my region, and when this didn't work, to a container region.
The scrollbars appear (horizontally and vertically) but they are greyed out as the region is still at max width and you have to use the browser to scroll instead.I think this looks untidy as the header colour-styling ends, as well as other regions being stretched.
I am using the below function to return a blob (CSV) content, this is working fine..But i need to modify this function to display headline for the report and fixed width column in CSV ( then user no need to expand the each and every column ).

I've installed Grid Control (aka OMS) 10.2.0.5 and try to look at the Database Performance. But instead of information I receive headers and blank picture in the place where usually all charts are shown. As a matter of fact it looks like the page tries to access that data source, but fails in that and shows just a symbol of picture that was not loaded and all menus from that page.
