Page zero - setting cache through database

Hi!
Just wondering, if you set caching properties of a region on page zero through the database will this trigger any problems in the application. If not, will the caching work if you manage it this way (because it is not possible to set those properties on page 0 through the application builder).
Thanks!

Do you mean that you will modify APEX schema tables data?
If you do that, then your instance is unsupported state.

How do I set cache to always reload a page?

I am in an online class and need to set cache to always reload a page. I do not even know what a cache is. I have just downloaded Firefox 18.

hello mdonovan1977, you could try the following: enter '''about:config''' into the firefox location bar (confirm the info message in case it shows up) & search for the preference named '''browser.cache.check_doc_frequency'''. double-click it and change its value to '''1''' - this should make the browser check for a new version of a page each time it is reloaded.

Page Zero (0) - Regions Caching / Page Caching not available

Hi,
My page zero display information from a calendar table (fiscal year, etc.). This information will be the same all day long (get updated at midnight). It's not possible to enable caching of regions on page zero. It's also impossible to enable caching of the page zero.
Why?
Thanks,

Louis-Guillaume,
Good question. We have asked ourselves this and are considering removing the restriction in 4.0. I think it initially had to do with preventing unwanted side effects and anomalies although none of us can recall the details right now. We will have to carefully look at ways to make this something developers can use easily while preventing strange results. First of all, caching of page 0 doesn't make sense. You want to be able to cache regions on page 0. Now, say your page 0 has two regions, P0_CACHED and P0_DYN (one cached, one dynamic). And your page 10 has region P10_CACHED. When page 10 is rendered, you'll get:
P0_CACHED
P0_DYN
P10_CACHED
That looks okay, you get one cached region from page 0, one dynamic region from page 0, and one cached region from page 10. Of course you have controls with which to purge any individual region from the cache so you can cause P0_CACHED to be refreshed whenever you like.
But say page 20 is a cached page. When it renders you'll get:
P0_CACHED <-- not from the page 0 region cache but from the page 20 page cache, regardless of the "stale-ness" of the page 0 cache
P0_DYN <-- not rendered dynamically from page 0 but retrieved as part of the page 20 page cache. But this content may be different from the content for the same page 0 region displayed on page 10 one second ago or one second from now.
P20_DYN <-- from the page cache as is normal for a dynamic region on a cached page
Hardly a thorough treatment, I realize. Just wanted you to know some of the aspects we have to consider. We will also have to read this thread again to come back up to speed: V3 Caching - any more info? .

Caching regions on global page zero

Hi all,
I'm trying to understand some use-cases to why caching global page regions wouldn't be viable. The documentation on region caching doesn't help me here, nor does it mention its availability on global pages - not that I saw, anyway.
It was covered [url https://forums.oracle.com/forums/thread.jspa?threadID=2214451]here in the forums 2 years ago, but two years is a long time.
I've been trying to eke out the best performance in an application, and I'm trying to identify regions that could be cached under certain circumstances.
I was a little surprised to find global page regions may not be cached, even bug 14744294 addressed in 4.2.1 for global pages that aren't "0"
Consider a dynamic list in the sidebar acting as a menu, deployed on the global page. Would this be a fair candidate, except perhaps for a "current page" sub-template.
I guess since many/most of these regions would have some sort of APP_PAGE_ID dependency, it's not worth caching?
Anyone have anything of interest to add to this discussion?
Cheers
Scott

Client side result set cache

Hello,
I try to get the client side result set cache working, but i have no luck :-(
I'm using Oracle Enterprise Edition 11.2.0.1.0 and as client diver 11.2.0.2.0.
Executing the query select /*+ result_cache*/ * from p_item via sql plus or toad will generate an nice execution plan with an RESULT CACHE node and the v$result_cache_objects contains some rows.
After I've check the server side cache works. I want to cache the client side
My simple Java Application looks like
private static final String ID = UUID.randomUUID().toString();
private static final String JDBC_URL = "jdbc:oracle:oci:@server:1521:ORCL";
private static final String USER = "user";
private static final String PASSWORD = "password";
public static void main(String[] args) throws SQLException {
OracleDataSource ds = new OracleDataSource();
ds.setImplicitCachingEnabled(true);
ds.setURL( JDBC_URL );
ds.setUser( USER );
ds.setPassword( PASSWORD );
String sql = "select /*+ result_cache */ /* " + ID + " */ * from p_item d " +
"where d.i_size = :1";
for( int i=0; i<100; i++ ) {
OracleConnection connection = (OracleConnection) ds.getConnection();
connection.setImplicitCachingEnabled(true);
connection.setStatementCacheSize(10);
OraclePreparedStatement stmt = (OraclePreparedStatement) connection.prepareStatement( sql );
stmt.setLong( 1, 176 );
ResultSet rs = stmt.executeQuery();
int count = 0;
for(; rs.next(); count++ );
rs.close();
stmt.close();
System.out.println( "Execution: " + getExecutions(connection) + " Fetched: " + count );
connection.close();
private static int getExecutions( Connection connection ) throws SQLException {
String sql = "select executions from v$sqlarea where sql_text like ?";
PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setString(1, "%" + ID + "%" );
ResultSet rs = stmt.executeQuery();
if( rs.next() == false )
return 0;
int result = rs.getInt(1);
if( rs.next() )
throw new IllegalArgumentException("not unique");
rs.close();
stmt.close();
return result;
100 times the same query is executed and the statement exection count is incemented every time. I expect just 1 statement execution ( client database roundtrip ) and 99 hits in client result set cache. The view CLIENT_RESULT_CACHE_STATS$ is empty :-(
I'm using the oracle documentation at http://download.oracle.com/docs/cd/E14072_01/java.112/e10589/instclnt.htm#BABEDHFF and I don't kown why it does't work :-(
I'm thankful for every tip,
André Kullmann

I wanted to post a follow-up to (hopefully) clear up a point of potential confusion. That is, with the OCI Client Result Cache, the results are indeed cached on the client in memory managed by OCI.
As I mentioned in my previous reply, I am not a JDBC (or Java) expert so there is likely a great deal of improvement that can be made to my little test program. However, it is not intended to be exemplary, didactic code - rather, it's hopefully just enough to illustrate that the caching happens on the client (when things are configured correctly, etc).
My environment for this exercise is Windows 7 64-bit, Java SE 1.6.0_27 32-bit, Oracle Instant Client 11.2.0.2 32-bit, and Oracle Database 11.2.0.2 64-bit.
Apologies if this is a messy post, but I wanted to make it as close to copy/paste/verify as possible.
Here's the test code I used:
import java.sql.ResultSet;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
class OCIResultCache
public static void main(String args []) throws SQLException
    OracleDataSource ods = null;
    OracleConnection conn = null;
    PreparedStatement stmt = null;
    ResultSet rset = null;
    String sql1 = "select /*+ no_result_cache */ first_name, last_name " +
                  "from hr.employees";
    String sql2 = "select /*+ result_cache */ first_name, last_name " +
                  "from hr.employees";
    int fetchSize = 128;
    long start, end;
    try
      ods = new OracleDataSource();
      ods.setURL("jdbc:oracle:oci:@liverpool:1521:V112");
      ods.setUser("orademo");
      ods.setPassword("orademo");
      conn = (OracleConnection) ods.getConnection();
      conn.setImplicitCachingEnabled(true);
      conn.setStatementCacheSize(20);
      stmt = conn.prepareStatement(sql1);
      stmt.setFetchSize(fetchSize);
      start = System.currentTimeMillis();
      for (int i=0; i < 10000; i++)
        rset = stmt.executeQuery();
        while (rset.next())
        if (rset != null) rset.close();
      end = System.currentTimeMillis();
      if (stmt != null) stmt.close();
      System.out.println();
      System.out.println("Execution time [sql1] = " + (end-start) + " ms.");
      stmt = conn.prepareStatement(sql2);
      stmt.setFetchSize(fetchSize);
      start = System.currentTimeMillis();
      for (int i=0; i < 10000; i++)
        rset = stmt.executeQuery();
        while (rset.next())
        if (rset != null) rset.close();
      end = System.currentTimeMillis();
      if (stmt != null) stmt.close();
      System.out.println();
      System.out.println("Execution time [sql2] = " + (end-start) + " ms.");
      System.out.println();
      System.out.print("Enter to continue...");
      System.console().readLine();
    finally
      if (rset != null) rset.close();
      if (stmt != null) stmt.close();
      if (conn != null) conn.close();
}In order to show that the results are cached on the client and thus server round-trips are avoided, I generated a 10046 level 12 trace from the database for this session. This was done using the following database logon trigger:
create or replace trigger logon_trigger
after logon on database
begin
if (user = 'ORADEMO') then
    execute immediate
    'alter session set events ''10046 trace name context forever, level 12''';
end if;
end;
/With that in place I then did some environmental setup and executed the test:
C:\Projects\Test\Java\OCIResultCache>set ORACLE_HOME=C:\Oracle\instantclient_11_2
C:\Projects\Test\Java\OCIResultCache>set CLASSPATH=.;%ORACLE_HOME%\ojdbc6.jar
C:\Projects\Test\Java\OCIResultCache>set PATH=%ORACLE_HOME%\;%PATH%
C:\Projects\Test\Java\OCIResultCache>java OCIResultCache
Execution time [sql1] = 1654 ms.
Execution time [sql2] = 686 ms.
Enter to continue...This is all on my laptop, so results are not stellar in terms of performance; however, you can see that the portion of the test that uses the OCI client result cache did execute in approximately half of the time as the non-cached portion.
But, the more compelling data is in the resulting trace file which I ran through the tkprof utility to make it nicely formatted and summarized:

Help needed in setting up Japanese Database

Hi there,
Help needed in setting up Japanese Database.
I created database with UTF8 character set on Sun Solaris O/S.
Oracle version 8.1.7.
I am accessing the DB through SQL*Plus (Windows client).
I downloaded the Japanese font on client side and also set the NLS_LANG environment variable to Japanese_Japan.UTF8. Still, I am not able to view Japanese characters. O/S on client side is Windows 2000 professional (English). Is O/S (client) need to be Japanese O/S? When I try to retrieve sysdate, its displaying in Japanese but not all characters in Japanese. Can anyone help me out how to set up the client and is there any parameters to be setup at server side? I also tried to insert japanese characters into table through client, but it displaying as "?????" characters. Any help in this regard is appreciated.
Thanks in advance,
-Shankar

lol
your program is working just fine.
do you know what accept does? if not read below.
serversocket.accept() is where java stops and waits for a (client)socket to connect to it.
only after a socket has connected wil the program continue.
try putting the accept() in its own little thread and let it wait there while your program continues in another thread

Items on page not set when called via hyperlink from charts

hello anyone who can help me on this thorny issue,
i have a barchart on one page (page 39), where if you click on the bar chart, page 40 opens and variables are passed on to items on page 40. the variables depend on which bar was clicked. looks somethiing like this:
select 'F?P=102:40:'||:APP_SESSION||'::NO::P40_DATE,P40_JAHR:'||to_char(datum, 'yyyy.mm.dd')||','||to_char(datum, 'yyyy') link,
to_char(datum, 'dd.mm.yyyy') Datum,
Avg_mips
from ... some sql query....
this generally works - BUT, once in awhile, the correct page opens, but the items are NULL!
only when i press F5 to refresh the page, do the variables correctly pass to the items and the proper query is performed...
after some testing, it seems to happen when i click quite fast. quickly get back to the page 39, click a new bar and then i'm back at page 40 again.
if i do this slowly, maybe wait a couple of seconds, it generally works.
for ex., the URL would look something like this:
http://daidalos:7777/pls/apex/F?P=102:40:2118535974571692::NO::P40_DATE,P40_JAHR:2008.12.16,2008
- i know the variables are correct when i look at the URL
- yet the new graph on page 40 shows null values, and a click on the "session" button confirms that the items are null!
- once i press F5, the URL is the exact same, onle the items are now "refreshed" and the proper processing can take place.
so, can anyone tell me what is going on here and how i can avoid this?
the items are set as "hidden" (not protected). there are no computations or default settings to the items, and they are not reset to null at any time.
regards,
mike

Mike:
I suspect that the chart on page 40 is being rendered by an APEX database connection that is not the same one that renders the rest of the stuff on page 40. So, it is possible that the database connection rendering the chart does not see the new values for the page items set in the URL as these may not have been committed to the database yet.
You could try this.
Change the chart query to be
select 'javascript:setStuff("' || to_char(datum, 'yyyy.mm.dd') || '","' ||to_char(datum, 'yyyy') || '")' link,
to_char(datum, 'dd.mm.yyyy') Datum,
Avg_mips
from ... some sql query...Add the JS below into the HRML page header<script>
function setStuff(p_date,p_jahr) {
$x('P40_DATE').value=p_date
$x('P40_JAHR').value=p_jahr
doSubmit('XXXX');
</script>Define an 'After Submit...' branch to page 40. Make the branch conditional on Request = 'XXXX'

Page Zero and Pop-up Windows

Hello:
I am trying to create a pop-up window that doesn't have some/all of the page zero regions. I don't want to create another page just for the pop-up window, I would like to use the same page but with(out) some privileges. I just don't want the user to be able to navigate to other pages (page zero lets you do that) from the pop-up window. Is there a way some/all page zero regions can be not shown when a pop-up window is displayed?
Thanks,
-Bino
Edited by: bino on Jun 2, 2010 7:11 AM

Hi Bino -- I'm not sure how you are bringing up your pop-up window, but you can set conditions on the regions in page 0 just like any other page so, for example, you could have a certain region not appear if the user is not logged on or if an item has a certain value, etc. If you are going to use an item value, when you bring up the pop-up window, you could set the value of that item right in the URL as one option.

Why can't I launch another app using a URL scheme in a web clip set up through Configurator with the "full screen app" option selected?

My company uses web clips on iOS devices, set up through profiles on Configurator, for EVERYTHING. Most of these web clips have a transfer function on the site that allows the user to bring up other apps, like directions to a destination in Google Maps for instance (a URL scheme.) If the option for the web clip to appear as a "full screen app" is selected in Configurator (or iPhone Configuration Utility), this fuction does not work on devices that are running iOS 7. It is imparative to our company that the web clips be full page so there is no address bar, back button, etc. for the users to access. With this feature not working, I have 50+ iOS devices that are usless to us.
iOS 6 Device --> Configurator 1.3 --> Full Screen Web Clip --> WORKS
iOS 6 Device --> Configurator 1.4 --> Full Screen Web Clip --> WORKS
iOS 6 Device --> iPhone Configuration Utility --> Full Screen Web Clip --> WORKS
iOS 7 Device --> Configurator 1.3 --> Full Screen Web Clip --> DOESN'T WORK
iOS 7 Device --> Configurator 1.4 --> Full Screen Web Clip --> DOESN'T WORK
iOS 7 Device --> iPhone Configuration Utility --> Full Screen Web Clip --> DOESN'T WORK
iOS 7 Device --> Configurator 1.3 --> NOT Full Screen Web Clip --> WORKS
iOS 7 Device --> Configurator 1.4 --> NOT Full Screen Web Clip--> WORKS
iOS 7 Device --> iPhone Configuration Utility --> NOT Full Screen Web Clip --> WORKS
Somebody, please help!

Phil, I have been trying to figure out a solution to this problem since iOS 7 came out. In hindsight, I should have downloaded the beta versions of the iOS so I would have had even more time. I have talked with quite a few different developers and up until today it was a consensus that this was a "feature" of iOS in an attempt by Apple to diminish the use of webapps. Now most of these people wouldn't be considered apple apologists by any stretch, which could have contributed to their pessimism. That being said, today I finally received some news that could give us a glimmer of hope. I spent almost 2 hours on the phone today being sent "up the ladder" until I think I found the right person to help (I'm not complaining; I was surprised at how competent and helpful each person that I spoke with was, and I didn't have to explain the situation over and over again.) I think what took so long finding the right person to speak with was that this isn't an issue that any type of troubleshooting would fix. It's not an iPad, iPhone, or even an Apple Configurator issue; it's actually a bug in iOS 7. Anyways, the senior engineer that I spoke with reassured me, very adamantly, that this was not a feature of the new operating system and most definitely a bug. He said that they take webapps very seriously and are actually looking for ways to improve how webapps work on iOS devices and how they are used with Mobile Device Management software, like Configurator. I was a little concerned that he said this was the first he or anyone on his team has heard about this problem, but he did work extensively with me today and said that it looks to be a major issue, and something that he and his team are going to try to figure out as soon as possible. He said he would be calling me by Tuesday with information on how and when this will be fixed. Jon

11g Client result set caching in OCI

I'm trying out this feature in the 11.1.0.6 release. My understanding of this feature is that when enabled with the appropriate server-side init.ora parameters, a 11g OCI client connecting to the instance will cache SQL results locally in some fixed amount of RAM on the client. The idea is that network roundtrips would simply disappear in this situation.
I'm not sure if it's working--or how to tell if it is. I have a 11g instance running and put the 11g client incl. sqlplus on a separate box, setting up TNS connectivity from client to server. Pretty standard stuff. I can connect fine and run the same query over and over, but I see incrementing execution counts on the database side and network traffic between the client and server so I'm guessing that the client-side caching isn't happening. There doesn't seem to be a ton of clear documentation on this feature so I wanted to see if anyone else has kicked it around.
Bob

I am also facing the same issue (enabling client result set caching). I am using Oracle Database 11g Release 11.2.0.2.0.
I have made the below configuration changes
1. Enabled the client result set cache by setting the server side parameter 'client_result_cache_size' to 10485760 (10 MB)
2. Restarted the oracle instance after setting the above parameter
3. Added a table annotation by executing the statement ALTER TABLE emp RESULT_CACHE (MODE FORCE). I verified that the annotation is applied by query the user table later.
4. Enabled statement caching on the client side i.e. on the JDBC driver.
5. Used prepared statements to execute the query so that statement caching kicks in. From the driver logs I verified that execution of subsequent queries after the first one used the same statement handle.
After executing the select prepared statement query for three times I checked the CLIENT_RESULT_CACHE_STATS$ view. But this view didn't result in any rows.
As part of troubleshooting I even tried adding the /*+ RESULT_CACHE */ hint to the query but the view didn't gave any result.
Also on enabling sql trace I could see from tkprof that every execution of the query increased the number of rows fetched on the server which indicates that the client result set caching in OCI isn't working.
Are there any steps which I have missed?
Thanks in advance.

Setting up mySQL database

I'm trying to set up mySQL database on my mid 2009 15" macbook pro running snow leopard.
I downloaded the dmg file and installed all three files on the dmg.
I can't connect to the database through the terminal or through system preference panel.
Does anyone have an idiot guide or walkthrough for setting up the database?

I'm not sure if this is going to help you, I think I used it at the time I set up MySQL:

Differences between BC Set SOLMAN40_CHARM_BASICFUNC_001 and database.

Hello Team,
We are configuring Change Request management in Solution manager.
Activation of BC sets ends with warning.Activation log shows below error.
'Differences between BC Set SOLMAN40_CHARM_BASICFUNC_001 and database. Check values'
There errors like "
Field Not Copied
Difference between BC Set and Table"
We are through with note :903527 which suggest "2) Create a new transport request (Transaction SE09) in the source client of your Solution Manager system. Unpack the file Piecelist_Change_Management_Init.zip, which is attached to this note. Copy the contents of the file Piecelist_Change_Management_Initial.txt into the transport request. Use Transaction SCC1 to import the transport request into your Solution Manager client"
But how to "Copy the contents of the file Piecelist_Change_Management_Initial.txt into the transport request"?
Please let me know if you have any hint.
Best Regards,
Tushar

Custom pagination for APEX 4.2 interactive report using Page Zero

Hi,
I want to implement an «Custom pagination for APEX 4.2 interactive report» using a «page zero».
I recently migrate from Apex 3.1 to Apex 4.2 and my «Custom pagination for APEX 3.1 interactive report» using a «page zero» is not working any more.
So now I try to adapt an excellent example of Jari Laine for 4.0 but using a page zero.
I put the code JavaScript to Page zero but I must create an dynamic action to fire only for an interactive report region.
It’s a good idea?
Thank you

Thought I would try once more with my DatePicker question.
On the Apex.Oracle.Com website I have created a 1 page application that has an Interactive Report.
[url http://apex.oracle.com/pls/apex/f?p=15655:1]
user = 'test'
password = 'test'
I have 2 questions :
(1) In IE7, press 'Actions', 'Filter'. On the Column dropdown list, select 'Order Timestamp'.
Notice the prompt icon to the right of the 'expression'. This should change to the Datepicker, but in IE7 it does not. Try the samething in Firefox or Chrome and the Datepicker will appear.
Is this a BUG, or does Apex 4.02 not support IE7 ?
(2) In Firefox or Chrome, where you can now see the Datepicker, you will notice that it is the new style picker, not the old style ( called 'classic' ). I want to change it so that it shows the 'classic' datepicker not the new, but cannot see how to do it, if indeed you actually can.
I would really appreciate it if someone could take a look and let me know if I am going mad, or if we need to get all our users onto IE8. We have now gone live with Apex 4.02 and need to resolve these issues.
Thanks in advance.

Current Patch Set for Oracle Database Release 11.2

Hi
I am upgrading oracle 10G to 11GR2 in AIX 5.3 Environment with SAP ECC6 , I have just just installled Oracle 11.2.0.1.0 according to the "Database Upgrade Guide -Upgrade to Oracle Database 11g Release 2 (11.2): UNIX". After database software installation , in upgrade manual in section 3.4.4 it says, you need to install current patch set for oracle database 11g R2 and referencing a SAP note 1431799.
I have just read note 1431799 which says Current Patch Set for Oracle Database Release 11.2 is not generally available for SAP customers until December 2010, also I donu2019t find the note 1522330 as mentioned in 1431799.
Please let me know how I can get current patch set to apply with Oracle 11.2.0.1.0 (Is it in SAP service market place?)
I also want to upgrade my installation to oracle 11.2.0.2, please let me know where I get the patch set to upgrade from 11.2.0.1.0 to 11.2.0.2,
or
I have to live with 11.2.0.1.0 and apply SAP Bundle Patch ( SBP)

Abu Al MAmun,
I understand from your posts that you recently upgraded to 11.2.0.2.
I am having the same difficulty, of finding the current patch set for 11.2. Could you please let me know how you worked around it?
Thanks,
Siri
Hello Everyone,
I did read the post on to how you have to install the current patch set for 11.2.
But honestly, it pretty much flew over my head.
I am trying to upgrade our SAP AIX 64 bit test system from Oracle 10.2.0.4 to 11.2.0.2.
And so far I have downloaded all the required sw for the upgrade, except for the current patch set 11.2.
This is what I have right now:
1) Oracle 11.2 AIX 64 bit upgrade sw - 51038805_part 1 to 51038805_part 7 and 51039800.
2) Database Patches -->Oracle 11.2.0.2 -->
All they have here is
a. Database RDMBS - SAP_112020_201012_AIX.zip and b. SAP_112020_201101_AIX.zip
b. OPatch - OPatch_11201_Generic_v3.zip and mopatch-2_1_6.zip
c. Database Vault - DV - >Generic - p9656644_112020_Generic.zip
If I am not wrong, the Database RDBMS files are nothing but the SAP Bundle Patches that have to be installed after installing the currrent patch set 11.2.0.2 using MOPatch.
But I did not find the currrent patch set 11.2.0.2.
Could someone please explain the process to me in detail? This being my first time , I am finding it a bit hard to catch up with some of the stuff.
Thank You!
Siri

So what happens when you connect to iTunes?
