Oracle Portal & 9iAS Database Cache

Has anyone used Oracle 9iAS database cache to speed up document retrieval from Portal? Can Portal be used to cache Portal documents remotely??
Any help greatly appreciated

Oracle TimesTen In-Memory Database VS Oracle In-Memory Database Cache

Hi,
What is difference in Oracle TimesTen In-Memory Database VS Oracle In-Memory Database Cache.
For 32 bit on windows OS i am not able to insert data's more than 500k rows with 150 columns (with combinations of CHAR,BINARY_DOUBLE,BINARY_FLOAT, TT_BIGINT,REAL,DECIMAL,NUMERIC etc).
[TimesTen][TimesTen 11.2.2.2.0 ODBC Driver][TimesTen]TT0802: Database permanent space exhausted -- file "blk.c", lineno 3450, procedure "sbBlkAlloc"
I have set Perm size as 700 mb,Temp size as 100mb
What is the max size we can given for PermSize,TempSize,LogBufMB for 32 bit on windows OS.
What is the max size we can given for PermSize,TempSize,LogBufMB for 64 bit on windows OS.
What is the Max configuration of TT for 32 bit what i can set for Perm size Temp size.
Thanks!

They are the same product but they are licensed differently and the license limits what functionality you can use.
TimesTen In-Memory Database is a product in its own right allows you to use TimesTen as a standalone database and also allows replication.
IMDB Cache is an Oracle DB Enterprise Edition option (i.e. it can only be licensed as an option to an Oracle DB EE license). This includes all the functionality of TImesTen In-Memory Database but adds in cache functionality (cache groups, cache grid etc.).
32-bit O/S are in general a poor platform to try and create an in-memory database of any significant size (32-bit O/S are very limited in memory addressing capability) and 32-bit Windows is the worst example. The hard coded limit for total datastore size on 32-bit O/S is 2 GB but in reality you probably can;'t achieve that. On Windows the largest you can get is 1.1 GB and most often less than that. If you need something more than about 0.5 Gb on Windows then you really need to use 64-bit Windows and 64-bit TimesTen. There are no hard coded upper limit to database size on 64-bit TimesTen; the limit is the amount of free physical memory (not virtual memory) in the machine. I have easily created a 12 GB database on a Win64 machine with 16 GB RAM. On 64-bit Unix machines we have live database of over 1 TB...

Oracle In-Memory Database Cache Testcases

We are implementing Oracle In-Memory Database Cache on an existing oracle database. We want to do some extensive testing on Oracle In-Memory Database. Can anybody please share some pointers in writing testcases ?

Best place to start is here:
http://www.oracle.com/technetwork/products/timesten/overview/index.html
In particular take a look at the Quickstart which is provided as part of the install of the product and can be accessed online here http://www.oracle.com/technetwork/products/timesten/learnmore/index.html via http://download.oracle.com/otn_hosted_doc/timesten/1122/quickstart/html/main/home.html
Take a look at the sample programs the tptbm program is a good place to start.

Portal and Database Cache

All,
Any pointers on using Portal with Database Cache. Can we identify Portal tables as 'hot', so that Portal page, content area rendering will be faster ? I was told that Portal and iCache have different approaches to caching. What if I turned off Portal caching and let iCache do it for me?
Would appreciate some response.
Thanks
Sanjay

The caching portal provides isn't a product. It's an optimization on the architecture, basically storing information wherever we can so it doesn't have to be pregenerated.

Oracle 9iAS Database cache

Hi
We are using Oracle 9iAS 9.0.3.
I am interested to confirm if the Database Cache technology supplied with previous versions of Oracle 9iAS app server has been phased out. Does Oracle 9iAS 9.0.3 support it?
Waiting for a quick reply.
Thanks All

kishore, I don't see any problem installing iAS on two different machines, if that's what you mean. Whatever you install on the 'second' machine will not affect the first. Since they have the different oraInventory location.

Sample PL/SQL Portlet Source Code for Oracle Portal 9ias

Hi, I'm a newbie of Oracle Portal technology, and I have a problem:
I would create a PL/SQL portlet that realizes the following functions:
1) Retrieve the username of the portal user logged from WWCTX_API.GET_USER function.
2) Insert into an oracle db table two values about two hidden fields in the HTML FORM of the portlet.
3) Realize the insert commit through the click on the submit button on the Html form of the portlet. I would redirect by the same button to an other page url also.
I've never developed in Portal, and may be useful if someone could post me the source code of the SHOW MODE SECTION in the PROCEDURE SHOW of a SAMPLE PL/SQL PORTLET that realizes the upper functions.
Thanks a lot....

Hi
Here's the code from Helloworld_Portlet example:
procedure show
p_portlet_record wwpro_api_provider.portlet_runtime_record
is
l_portlet wwpro_api_provider.portlet_record;
begin
if (not is_runnable(
p_provider_id => p_portlet_record.provider_id
,p_reference_path => p_portlet_record.reference_path)
) then
raise wwpro_api_provider.PORTLET_SECURITY_EXCEPTION;
end if;
Retrieve the portlet information.
l_portlet := get_portlet_info(
p_provider_id => p_portlet_record.provider_id
,p_language => p_portlet_record.language
if (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW) then
if (p_portlet_record.has_title_region) then
Draw the portlet header and specify what links are available
from that header (i.e. details, customize, help, and about).
The has_title property is set at the page region level.
wwui_api_portlet.draw_portlet_header
p_provider_id => p_portlet_record.provider_id
,p_portlet_id => p_portlet_record.portlet_id
,p_title => l_portlet.title
,p_has_details => true
,p_has_edit => true
,p_has_help => true
,p_has_about => true
,p_referencepath => p_portlet_record.reference_path
,p_back_url => p_portlet_record.page_url
end if;
Draw the portlet borders.
The has_border property is set at the page region level.
wwui_api_portlet.open_portlet(p_portlet_record.has_border);
Display the content of the portlet in the show mode.
Use the wwui_api_portlet.portlet_text() API when
generating the content of the portlet so that the
output uses the portlet CSS.
htp.p(wwui_api_portlet.portlet_text(
p_string => 'Hello World - Mode Show'
,p_level => 1
if (p_portlet_record.has_border) then
wwui_api_portlet.close_portlet;
end if;
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_ABOUT) then
Display the about page for the portlet.
htp.p('Hello World - Mode Show About');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_EDIT) then
Display the edit page for the portlet.
htp.p('Hello World - Mode Show Edit');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_HELP) then
Display the help page for the portlet.
htp.p('Hello World - Mode Show Help');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_EDIT_DEFAULTS) then
Display the edit defaults page for the portlet.
htp.p('Hello World - Mode Edit Defaults');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_DETAILS) then
Display the details page for the portlet.
htp.p('Hello World - Mode Show Details');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_PREVIEW) then
Display the preview page for the portlet.
htp.p('Hello World - Mode Show Preview');
end if;
end show;
I think you need to add this:
You can get the values of your html-form with this command:
v_hidden_1 varchar2(256);
v_hidden_2 varchar2(256);
v_hidden_1 := wwpro_api_parameters.get_value('name_of_hidden_1_in_html_form','p');
v_hidden_2 := wwpro_api_parameters.get_value('name_of_hidden_2_in_html_form','p');
You can get the actual URL with this command:
v_url := p_portlet_record.page_url;
Hope that helps.

Mark

"In-Memory Database Cache" option for Oracle 10g Enterprise Edition

Hi,
In one of our applications, we are using TimesTen 5.1.24 and Oracle 9i
databases (platform - Solaris 9i).
TimesTen holds application information which needs to be accessed quickly
and Oracle 9i is a master application database.
Now we are looking at an option of migrating from Oracle 9i to Oracle 10g
database. While exploring about Oracle 10g features, came to know about
"In-Memory Database Cache" option for Oracle Enterprise Edition. This made
me to think about using Oracle 10g Enterprise Edition with "In-Memory
Database Cache" option for our application.
Following are the advantages that I could visualize by adopting the
above-mentioned approach:
1. Data reconciliation between Oracle and TimesTen is not required (i.e.
data can be maintained only in Oracle tables and for caching "In-Memory
Database Cache" can be used)
2. Data maintenance is easy and gives one view access to data
I have following queries regarding the above-mentioned solution:
1. What is the difference between "TimesTen In-Memory Database" and
"In-Memory Database Cache" in terms of features and licensing model?
2. Is "In-Memory Database Cache" option integrated with Oracle 10g
installable or a separate installable (i.e. TimesTen installable with only
cache feature)?
3. Is "In-Memory Database Cache" option same as that of "TimesTen Cache
Connect to Oracle" option in TimesTen In-Memory Database?
4. After integrating "In-Memory Database Cache" option with Oracle 10g, data
access will happen only through Oracle sqlplus or OCI calls. Am I right here
in making this statement?
5. Is it possible to cache the result set of a join query in "In-Memory
Database Cache"?
In "Options and Packs" chapter in Oracle documentation
(http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/options.htm
#CIHJJBGA), I encountered the following statement:
"For the purposes of licensing Oracle In-Memory Database Cache, only the
processors on which the TimesTen In-Memory Database component of the
In-Memory Database Cache software is installed and/or running are counted
for the purpose of determining the number of licenses required."
We have servers with the following configuration. Is there a way to get the
count of processors on which the Cache software could be installed and/or
running? Please assist.
Production box with 12 core 2 duo processors (24 cores)
Pre-production box with 8 core 2 duo processors (16 cores)
Development and test box with 2 single chip processors
Development and test box with 4 single chip processors
Development and test box with 6 single chip processors
Thanks & Regards,
Vijay

Hi Vijay,
regarding your questions:
1. What is the difference between "TimesTen In-Memory Database" and
"In-Memory Database Cache" in terms of features and licensing model?
==> Product has just been renamed and integrated better with the Oracle database - Times-Ten == In-Memory-Cache-Database
2. Is "In-Memory Database Cache" option integrated with Oracle 10g
installable or a separate installable (i.e. TimesTen installable with only
cache feature)?
==> Seperate Installation
3. Is "In-Memory Database Cache" option same as that of "TimesTen Cache
Connect to Oracle" option in TimesTen In-Memory Database?
==> Please have a look here: http://www.oracle.com/technology/products/timesten/quickstart/cc_qs_index.html
This explains the differences.
4. After integrating "In-Memory Database Cache" option with Oracle 10g, data
access will happen only through Oracle sqlplus or OCI calls. Am I right here
in making this statement?
==> Please see above mentioned papers
5. Is it possible to cache the result set of a join query in "In-Memory
Database Cache"?
==> Again ... ;-)
Kind regards
Mike

Oracle Portal with Oracle Web Cache

How can I configure Oracle Portal (or Web Cache) to work together?
I have installed and started both of them. Now, Web Cache works fine with standard html pages (for example Apache docs) but after trying to reach portal the url is redirected to standard port - on which Portal runs (Web Cache works on 1100 and Portal on 7778).
So it seems that portal pages are not cached.
Web Cache:
Application Web Servers:
hpwin 7778 100 30 5 / 10
Where can I find any information about that?
best regards
KJ

Portal PM, I thought you said that this solution would not work. Everyone I have heard so far has said that you cannot configure webcache to work with Portal documents. Does this work or does it not?
Read the messages below from the bottom up.
It's not possible to do that today.
In 9.0.2 (the next release) we will be using WebCache configured out of the box so you won;t need to, however, till then you cannot use webcache with Portal 3.0.x
Thanks
Portal PM

please try using this configuration on http.conf
Port <webcache port>
Listen <apache listen port>
ServerName <webcache hostname>
you must running ssodatan script again.
Note :
this config only make portal work together with webcache.

Database Cache and Gateways

We are considering using Oracle Database Cache to speed up a web application that reads data from a mainframe database. Since Database Cache only works with Oracle databases, we plan to create a new Oracle database that acts as a gateway (using ODBC) to the mainframe.
The question we have is whether this would be possible and would make sense from a performance perspective. It is possible that Database Cache makes clever use of Oracle metadata (table update timestamps, etc) which would not be available for tables linked through ODBC. In this case, Database Cache might not work properly.
Is it possible to configure Database Cache in such a way that that the application reads data from the mainframe only when the data in the cache is more than an hour old?

Hi
I have a question regarding the 9iAS database cache: when I
select a table to be cached, does the cache also pull up the
indexes definition from the origin database? Another way to put
it: if I cache a table which has an index on the PK ( on the
origin database ), is the index also created on the db cache or
it performs a full scan for every query?
Thanks

Install Portal and Database with modem turned off?

I am about to install Oracle Portal 9iAS with Oracle 8i database in a Win2000 PC. I have a cable internet connection that uses DHCP to dynamically assign IP and DNS addresses. Would DHCP be a problem? Should I make the installation with the modem turned off?
Thank you very much,
Melissa

I installed Portal and Database on my machine at home which has both a public and private IP and there were NO problems doing it with the modem on and connected.

Oracle Portal Configuration Assistant will not connect

I am attempting to install an Oracle Portal 9iAS with the software provided in the book "Application Server Portal Handbook" by Seve Vandivier and Kelly Cox.
Ok, all goes well until I get to the Portal Configuration Assistant. I want to connect to the database (on a different box over the network) and install the repository.
No go. I cannot login. I know the password for SYS. but the connect descriptor it is looking for should be noodle:1521:fastdb (noodle is the host, 1521 the port, fastdb the SID).
I cannot figure out why this does not connect. If I open a SQLplus window on this computer, I can connect successfully, although this would use a TNS connection, which is not the same.
So, where am I going wrong?????
One more clue, the book talks about connecting to an Oracle 8i database, and I am trying to connect to an Oracle 9i database. Does this matter???
Any help would be appreciated!
Thanks,
Edward

Assuming you are installing 9ias Rel1 with portal 309.
Apply the RDBMS 8.1.7.4 patch to the 9ias Oracle Home and re-run the configuration assistant. It's been awhile since I've had to install Rel1, but that was the fix when we last asked oracle about it.
