Oracle times ten

Hi ,
Any idea where we use this times ten in memory for oracle ?
Is it part of oracle applications or database.what exactly is its functionality ?
thanks!

It is a completely separate product. Basically it is a database engine and responds to SQL requests. However, it uses a different stucture and is optimized to working in memory and not block oriented as is the traditional Oracle database. As a result, it works screamingly fast for databases that can fit entirely in memory.
It is occasionally used as a front end, or cache, to the traditional Oracle database.
If you want to get more information, you could look at Oracle's [TimesTen portal |http://www.oracle.com/technology/products/timesten/index.html] and communicate with people who actuvely use it in the [TimesTen forums|http://forums.oracle.com/forums/forum.jspa?forumID=244]

Can Oracle Times Ten be used effectively in OLAP ?

Hi ,
Can anyone let me know if using Times Ten in OLAP /datawarehousing increase the throughput or have faster response times?
Thanks.

That's a very general question and so of course the answer is 'it depend' :-)
We do have customer using us in this kind of environment but it really depends on the voilumes of data involved and the type of queries being run.

Oracle / HTML DB and Times Ten

Hi
Just thinking aloud here really, but has anyone thought about using HTML DB against the new (to Oracle) Times Ten in-memory database. Apparently TT supports access via ODBC or JDBC or just regular SQL, so it should be possible to connect a regular Orace Db with HTML DB in it to an in-memory TT db.
Is this a stupid idea, does it have any real benefits, what does anyone think.
Jules

The benfits would be enormous. Basically, what used to require a round trip through the network would now come directly from RAM on the same machine as the application. However, I don't know how you would hook the 2 up. As far as I can tell, HTMLDB can only connect to an Oracle DB. If you did something hokey like use Heterogeneous Services to connect to TimesTen, you'd lose the whole benefit of the in memory architecture (cause you'd have to go through the DB to get the information).
I think we have to wait until HTMLDB becomes DB agnostic (or the write special DAD connectors for TT).

Unable Update SQL Developer with Times Ten in-Memory DB Extension 1.2.1.1.0

SQL Developer 1.2.1 Build MAIN 32.13 (Windows XP)
We can't Update SQL Developer with Times Ten in-Memory DB Extension 1.2.1.1.0 :-((
We did the same actions as described in tutorial
http://www.oracle.com/technology/products/timesten/viewlets/tt703_sqldev_install_ext_viewlet_swf.html
In addition to tutorial we have "Log In" window
"To download Oracle Times Ten in-Memory Database Extension
you must enter your Oracle Web Account user name and password"
This window was not displayed in tutorial...
We try to use three our OTN accounts and the result
was the same - we was asked with "User name" and "Password"
again, again, again and again,,, :-(
Is it a bug or a feature?
Mayby we didn't understand something or did something wrong?

Hi Simon,
I found cause of update failure! It was the HTTP proxy setting.
I turned off "Use HTTP proxy server" checkbox in SQL Developer -> Tools -> Preferences -> Web Browser and Proxy.
After this action SQL Developer was successfully updated with Times Ten Extension.

Times ten not scaling how to speed up.

Hello Everyone,
I am doing evaluation of times ten to use it as cache but it is not scaling in my test bed:
From the http://vimeo.com/28397753 demo it seems it can do 5 million transaction per minute by in my test bed which is 4 gb machine it is taking sweet 140 seconds to insert 100 K records almost 120 times slower!
I have only one table with a integer column and only one index on that column which is not unique.
TermSize: 1024m
PermSize: 2024m
We want a scallable solution that can go upto 250 Million records in a table (and we will have two such table other will be smaller) is it possible with times ten?
Our queries will generally requst 50K results and we will have 12 fields in this table numeric and integer that we are going to separately index.
Look up also on a one integer table are taking about 100 milliseconds.
I am using a TimesTenDataSource ds = new TimesTenDataSource();
String URL = "jdbc:timesten:direct:TT_1121";
I tried doing batch inserts of 25,100,500,100 rows per insert with not much improvement.
Is oracle times ten even fit for such a case?
thanks and regards,
sumit

You say that your machine has 4 GB RAM but you have allocated over 3 Gb to TimesTen. That's fine if there is pretyt much nothing else running o nthe machine but if you have otjer things (such as Oracle DB maybe?) running o nthe machine at the same tiem then you are likely running low on memory. Are you seeing significant page in and pageout acticity when the test runs? If so this will seriously impact performance.
Can you please provide:
1. A description of the overall hardware and software environment that you are using for the test.
2. The exact TimesTen version (output of ttVersion) command.
3. The DSN configuration (from sys.odbc.ini)
4. The actual table (or cache group) defintiion including any indexes.
5. Details of the Java test program. In particular; are you using parameterised INSERT statements? Are you preparing them just once and executing them many times? How often do you commit during the bulk load? etc.
Thanks,
Chris

Can not create user in Times Ten 7

Hi All,
I have installed Oracle Times Ten 7.0.4 in my machine. To connect to the databse I have used "connect RunDataCS_tt70_32;" which I found from the ODBC. (I even dont know whether this the correct way to connect or not). Now I have tried to create a user (" create user prashant identified by 'p1'; ") but the command failed saying "15007: Access control not enabled".
Can anybody tell me how can I create a user in Times Ten.
Thanks,
Prashant

To be able to create users and have access control applied you must install TimesTen with Access Control enabled (it is an optional feature). When you did your install you replied no (or took the default) to the question 'Do you want to enable Access Control?' (or you did not tick the relevant check box if you are using Windows).
You can enable Access Control for your installation by running the command
ttmodinstall -enableAccessControl
you need to do this as the instance administrator user (the O/S user who installed the TimesTen instance).
I would strongly advise that you read through the TimesTen QuickStart Guide and other tutorial on the TimesTen OTN site beofre trying to use TimesTen as it will save you a lot of time and many questions to this forum :-)

Unable to insert into oracle db using times ten

I have a times ten 6.0 installation on my m/c connected to an oracle 10.2.0.2 database. The database is a remote database. My application is deployed to oracle application server (10.1.3.1 SOA). I am getting the following SQLException when I try to insert.the first row.
java.sql.SQLException: [TimesTen][TimesTen 6.0.4 ODBC Driver][TimesTen]TT5105: OCI initialization failed. -- file "bdbEnv.c", lineno 275, procedure "ttBDbEnvAlloc"
My env is as follows
OS = Windows 2000
DataSource = User DSN
First Connection
Permanent Data Store = 100
Temporary Data Store = 50
Connections = 20
Synchronous write through cache
I tried a select on the table before insert and it worked. Using ttisql I can insert into this table without any problem. Using a standalone java program I am able to insert data into this table. But from within an appserver I am facing this issue.
Thanks in advance for any help.
Regards,
Mahesh.

Jimmyb,
Are you logged in as the user that owns that table?
Yes.
If yes, then there are no triggers on this table.
That is true.
You will need to populate the ID column with your insert statement.
Just did that.
Usually, the sequence is very similar to the table name.
Yes I tried few of them in my sql query and it said "sequence cannot be found"
Isn't there some way that it will list the name of the sequence currently being used in a table?

Times ten to improve performance for search results in Oracle eBS

Hi ,
We have various search scenarios in our ERP implementaion using Oracle Apps eBS, for example searching for an item . Oracle apps does provide item search but performance is not great. We have about 30 million items and hence to improve the performance of the search thought Times ten may help.
Can anyone please clarify if Times ten can be used to improve performance on the eBS database , if yes how.

Vikash,
We were thinking along the same lines (using TimesTen for massive item search in e-Business Suite). In our case massive Item / parametric search leveraging the Product Information Management application. We were thinking about setting up a POC on a Linux Server with a Vision Instance. We should compare notes?

Use of Times ten database with Oracle Forms 11g

Hi,
We need to use some caching / pre-fetching solution with Oracle Forms 11g. Is there a possibility that Oracle Forms 11g can be used with Times ten database.
Regards,

We have never tested TimesTen with Forms 11g but we suspect there are issues that may prevent if from being used.
Sorry.

Caching configuration (Times Ten - Oracle 10g)

Hi all,
I have managed to setup Times Ten and get a cache group configured against a table in an oracle 10g instance.
That all works so great. My question is how do I define a set of cache groups and get Times Ten to load them in automatically all together. So what I am saying, is I dont want to have to enter these cache group definitions in manually via ttisql command line (as I have done this time).
Could someone please point me in the right direction with this? Also I would like to be able to set TT up such that the cache agent is automatically started. Is this possible?
Thanks,
Dan

Hi Dan,
In the same way that you can create cache groups through a ttIsql script you can also load them from a script using the LOAD CACHE GROUP and REFRESH CACHE GROUP commands.
However, let's remember that TimesTen is a persistent database and so you should not need to re-create the cache groups nor re-load them just becasue you have stopped and started TimesTen. The cache group definitions and data will still be present as they are persistently stored. Also, if you have a READONLY or USERMANAGED cache group using AUTOREFRESH then the changes that occur in oracle are captured and refreshed to the cache group(s) automatically.
As for starting the cache agent 9or the repagent0 automatically, this kind of depends on how you are managing the startup/shutdown of the cache datastore (i.e. what itss ramPolicy is). You can set the cachePolicy for the datastore using ttAdmin as follows:
ttAdmin -cachePolicy always DSNname
this tells TimesTen that the cache agent should always be running for this datastore. However, a side effect of this is that the datastore will allways be loaded in memory when the TimesTen instance is up (i.e. the TimesTen main daemon is running). If you want to be able to start and stop the datastore manually (or from a script) then you will likely be using a ramPolicy of manual and running some script to load/unload the datastore into/from memory. If so then just add the relevant ttadmin -cacheStart|-cacheStop commands to that script.

Is Oracle database Compatible with Times Ten database?

Hello All,
I need to use a temporary database in Oracle for some months.
Later on, I will need to migrate all data to a Times Ten database.
1. My doubt is if Oracle and Times Ten databases are compatible with
each other (specially when having this kind of cases) ?
2. In case the answer is YES to question 1, I would like to know if there are some
restrictions in that compatibility (type of data, any other issue, etc)
Best Regards
Rubén

Ruben,
There are two areas you shoul look into regarding your project: SQL functionality and data types. TimesTen 6.0 supports a subset of the SQL features and data types currently available in the Oracle DB; also, TimesTen supports some native numberic data types that are not available in the Oracle DB.
If your end-game is to use the TimesTen database, then I would start with the TimesTen API and SQL Reference Guide (http://www.oracle.com/technology/documentation/timesten_doc.html)
Use the SQL functionality documented for TimesTen and pay attention to the common data types. For example, VARCHAR is handled differently from VARCHAR2 (where trailing spaces exist), DATE and Timestamp are handled differently, etc. Additionally, keep in mind most numeric values are declared using NUMBER in the Oracle DB, but not in TimesTen.
If you are an existing TimesTen licensed customer, please let us know your support ID(CSI) and we can contact you with more information on our future release plan to address SQL and data types compatibility.
By the way, what's the timeline for your project?
