Hi Pratheej,
These vulnerabilities were fixed in 11.2.1.6.1 and 7.0.6.2.0. As you are on 11.2.1.8.4 you are okay for 11.2.1 but the 7.0.5.16.0 release does contain the vulnerability. If you are concerned then you should upgrade those to 7.0.6.2.0 or later (check for the latest applicable 7.0 release in My Oracle Support).

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...

Application connection to TimesTen In-Memory Database

Hi All,
We're in the planing of creating TimesTen In-Memory Database for our production databases.Now we're in testing phase,we made one TimesTen In-Memory Database for one test database.
Now we don't want to put all database in memory, we've some selected tables for some users,we only want these tables will by in memory, so we create cache group & add theese tables in that.
Now some of my database is in memory & some database is not in memory,so I want to know that how the application users will connect to database ??
Is they connect to TimesTen In-Memory Database or our main database ???
If they connect to TimesTen In-Memory Database how they will access the procedures of functions etc from main database ???
Or If they connect to main database how these TimesTen In-Memory Database tables will access by users ???
Is TimesTen In-Memory Database will help only when we put whole database in memory ???
Thinks & Regards,
Atul Mandale.

Hi Atul,
If you want to cache all your database then just create cache groups to encapsulate all your tables. That is the only way. However, I am far from sure this would be a good idea...
TimesTen is not a transparent, 'just plug it in' performance accelerator (such a thing does not exist and probably never will). It is intended to solve specific problems i.e. when some or all parts of an application need 'real time' access to some database data and the performance requirements (usually response time but sometimes throughput) are such that they either cannot be met at all, or cannot be met cost effectively, using Oracle DB or RAC alone. If one has that kind of situation then TimesTen may be able to help. It is unlikely to help a general application scenario just by plugging it in. Note that to successfully implement TimesTen it is almost always necessary to make both application and architectural changes. Why is this?
1. You are moving from a single DB to a multi-DB solution. Each item of data can be mastered (i.e. be updateable) in only one DB - Oracle or TimesTen. All parts of the system must understand this and enforce this or dat inconsistency may result.
2. All the data held in TimesTen must fit into physical memory. Data storage requirements often increase when moving a table from Oracle to TT. If you have a table that takes up 5 GB in Oracle it may well need 8 GB or more of memory in TimesTen. Unless your Oracle database is quite small you will need a machine with a very large amount of memory to cache the whole DB in TimesTen.
3. Queries and transactoons cannot span data in TT and Oracle. Any given query or transaction must execute entirely in TimesTen or Oracle.
4. Depending on which tables are cached and which are not, some application componenst may need to be aware of the location (TT or Oracle) of specific tables/data and go to the right place to get it. The TimesTen PassThrough feature can certainly help a lot with this but it does not necessarily address every possible issue.
5. Today, TimesTen only supports ODBC and JDBC APIs. If you have an application that uses OCI it must be recoded to use ODBC. The next major release of TimesTen does support OCI.
6. TimesTen does not support triggers or PL/SQL. The next major release supports PL/SQL and we have our own proprietary event notification API called XLA.
7. Although the SQL supported by TimesTen is a large subset of Oracle SQL there are still incompatibilities and some datatypes (e.g. CLOBS/BLOBS is on example) that TimesTen does not support.
While it may be possible to cache all your database it may not be a very practical, or beneficial, way to go. Can you share a bit of detal about the problem you are trying to solve with TimesTen so that maybe we can advise you of the best approach?

TimesTen In-Memory Database -ORA-00942: table or view does not exist rc = -1

Hi Chris,
This is wrt the thread : Unable to create CacheGroup.
I have configured Oracle_DB[11.2.0.3.0] for timesten, installed timesten[11.2.2.7.0], configured cache_DB.
So the Oracle database has user TIMESTEN(cache user) and TTENADMIN(cache admin user). Similarly the Cache Database has same TTENADMIN(cache manager user) and FNETLUO1(cache table user)
But while configuring the cache database following error occurred:
connect "dsn=my_cachedb;uid=TTENADMIN;oraclepwd=ttenadmin";
Enter password for 'TTENADMIN':

Please advise how we can solve this?

Hi
Just for additional information:

But i can see that at backend two new tables are created for TTENADMIN(cache admin):
TTENADMIN.TT_06_DATABASES and TTENADMIN.TT_06_DB_PARAMS
with columns, indexes but no records/data.

Oracle 12c in- memory database option

I did not go to oow 2013, but watched Larry Ellison's video on Orcle 12c in memory option. Seems amazing tecnology, hard to beleive everything can be done behind the scene once one sets some parameters in init.ora. I alreday have 12.1 intsalled on OEL 6.4 on my VMWare, wbat to play with it but do not see any download links on technet.oracle.com.

It's just announced so wait for some time and I believe, it's not going to take "just few parameters" only.

Two questions about TimesTen In-Memory Database

1.
In TimesTen, there are two methods to do the replication:
a. create active standby pair
b. create replication tt element ...
whose performence is better ? when the cache group exists, only the A/S can be used, is it right?
2.
If I just want to store the data in memory, how to stop the changes of the data from logging to the disk?

Hi,
Regarding your queries
1) Each replication type has its own benifits. Active -standby is used mostly for High availibility systems, while the classic replication scheme is mostly used for load sharing and distributed workload.
Cache group will work well with Active standby pair. Using cache group with class replication systems is not encouraged.
2) Disabling logging is something which was provided in TT 7.x(DSN attribute LOGGING) but no more allowed in latest TT releases like 11.2.1.x or 11.2.2.x.

Oracle In-Memory Database Cache

Hi,
I was reading about Oracle in Memory database cache and i am wondering is this option available on 10g, from what i read it is only on 11g and it is extra option and have to pay for it.
Any more info, will be great.
thanks

From here
The In-Memory Database Cache option of Oracle Database Enterprise Edition is based on Oracle TimesTen In-Memory Database.TimesTen is also available for 10g.

Oracle Import In 817 Database

Hi,
I've a couple of tables that has a million records or more and occupying some 300MB of space.I export these tables with no data (using the ROWS=N option). When I try to import these tables from the .DMP file, the tables gets created with 300MB of space or more as available in the .DMP file. Is there any way in which I could ignore the storage clause available in the .DMP file. Please let me know at the earliest.
Thanks in advance.

Jai.

"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 Timesten Error

Hi,
I'm sorry to post my question here,I just don't know where to the proper location for this one. By anyway, if somebody to help me out here it would be great and I will deeply appreciate it.
We are testing the oracle times-time database cache on our oracle 10g development server. We are going to what would be the effect or changes our apps data retreival. I was able to install times-ten, but when I'm trying to cache a database I having some errors somthing about
"ttOCIEnvNlsCreate."
I have followed the steps in your quick tutorials and end up with this error.I think it has something to do with the wrapping of the database characterset. Kindly advise on what to do.
thanks

TimesTen doesn't support the CONTEXT indextype or CONTAINS clause (or other domain indexes/operators), so you can't create Oracle Text indexes in it.

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.

Oracle ADF with HSQL In-Memory Database

Hi
I have been using J2EE applications and have several Junit test cases using Hibernate and HSQL in-memory database.
I am looking to migrate some of the modules in the project to ADF.
Can the unit test cases be implemented with ADF, running without Oracle Database?
In simple words will ADF work with HSQL in-memory database?
Thanks,
Ram

Vinod
In the link http://vtkrishn.wordpress.com/2010/03/29/configure-hibernate-for-jdeveloper/
Hibernate is configured with Oracle database..Not with HSQL
So I am not very sure if ADF works with HSQL

Limitation of Oracle Timesten Database

Hi,
We want to deploy the Oracle Timesten11.2 on 64bit RHEL Platform.
Total Physical RAM Size in Server is 32 GB.
There are 40 Millions rows in single subscriber table(45 Columns) in Oracle Database
We want to configure the READ-ONLY-LOCAL CACHE in Oracle Timesten for this subscriber table.
What should be the size of Oracle Timesten Database for support the above configuration.
Regards
Hitgon

Hi hitgon,
You can use the ttSize utility (http://docs.oracle.com/cd/E21901_01/doc/timesten.1122/e21643/util.htm#CHDEHFIE) for prediction the size.
Example: ttSize -tbl tableName -rows 40000000 your_DSN
Additionally, you can use ttComputeTabSizes function and tablesize clause for getting the actual table size
Command> call ttComputeTabSizes('emp');
Command> tablesize emp;
Sizes of GENA.EMP:
INLINE_ALLOC_BYTES:   0
NUM_USED_ROWS:        0
