Cache connect for Oracle

We have an application which calls PL/SQL stored procedures in an Oracle 9 Db. Is there any way to use the cache connector for Oracle where the application will use the TT DB instead of the Oracle DB without needing extensive changes to the application?
Any help is appreciated!

Hi user487815,
The TimesTen IMDB does not support PL/SQL stored procedures. For your application, you should select the performance critical procedures and convert them to either ODBC or JDBC SQL calls.

"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.

Pre-production box with 8 core 2 duo processors (16 cores)

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

Unable to use Cache connect to oracle

Hi Friends,
I am using TimesTen Cache connect to oracle to connect to Oracle 9i. When I tried to
Command> call ttCacheUidPwdSet('testuser','mypsswrd'); it gave me an error saying
"con1: Command> call ttCacheUidPwdSet('TestUser', 'prashant');
Warning 5105: OCI initialization failed: Error due to failure of ttOCIEnvNlsCre
ate (called from ttBDbEnvAlloc/ttBDbInit).
Warning 5109: Cache Connect general error: BDB connections not open."
can anybody tell me what could be the problem.
And to use cache connect is there a separate installation ? or setting ?
Thanks,
Prashant

What exact version of Oracle client is installed on the TimesTen machine? Are the permissions for the Oracle client directory and files set correctly? Do you have your Oracle environment properly setup (i.e. can you connect to Oracle using SQL*PLUS)? When you installed TimesTen, did the user you used to install it have a valid Oracle environment?
This type of error is almost always due to an unsupported version of the client or an incorrect environment either at runtime or at installation time.

Does TT cache connect support Oracle 8.1.7.4 as backend database?

Can TT (702) cache connect support Oracle 8.1.7.4?
thanks

No, I'm afraid not. We only support 9.2.0.8 or 10g. There is no longer support for 8i.
Sorry,
Chris

Can't Create the ODBC connection for Oracle 10g

Hi,
I am working with Oracle 10g Database Release 2 in windows XP professional. I am trying to create an ODBC connection for oracle but become failure because its generating the following errors:
system error code 998
could not locate the setup or translator library
Please help me how can I solve this problem and create the ODBC connection for oracle 10g database.
Best Regards,

could not locate the setup or translator libraryThe symptom described is typical of an incorrect system env PATH setting (used by the data source admin tool), compared to that of the Oracle Home (specifically, path $OH/bin). The odbc driver config routine will search directories listed in PATH variable for necessary libraries (Client dll's). If some library fails to load (from e.g. oraoci*.dll or oraclient10.dll) it will probably error out, as in your case.
Are you creating the odbc dsn on the databse server host or on some other machine? I.e. are you using the db host as a client or not?

You don't need a DSN if you use Oracle's JDBC driver.

[JTA_Start_0]Exception getting connection for Oracle DB

Hi All,
I am facing a problem when I am going to insert data in a table (Oracle DB) using JTA Command Action block. I have deployed the Oracle JDBC driver and Configured the data source in http://<server<:port>>/nwa->Configuration Management -> Infrastructure. But when I am trying to insert data using the JTA Command Action block for inserting data in a table it is throwing error.I am running with XMII 12.1 SP5 and Oracle 11g.
Here is the error details.
[ERROR] [JTA_Start_0]Exception getting connection for jdbc/ODS_ORACLE_SBX was ResourceException occurred in method ConnectionFactoryImpl.getConnection(): com.sap.engine.services.connector.exceptions.BaseResourceException: Cannot get connection for 0 seconds. Possible reasons: 1) Connections are cached within SystemThread(can be any server service or any code invoked within SystemThread in the SAP J2EE Engine) or they are allocated from a non transactional ConnectionFactory. In case of transactional ConnectionFactory used from Application Thread there is an automatic mechanism which detects unclosed connections, 2)The pool size of adapter "ODS_ORACLE_SBX" is not enough according to the current load of the system . In case 1) the solution is to check for cached connections using the Connector Service list_conns command or in case 2), to increase the size of the pool.
Note: ODS_ORACLE_SBX is the Data source name which I have configured.
If I increase the min pool size from 0 to 5 or more than 0 then Data source is getting red means not Available.
Can anybody provide any help.
Thanks in advance

You set up your Oracle DB connection by following the path 'xMII Menu -> Data Services -> Data Servers -> New'.

Cache connect to oracle

i have timesten in windows xp. my timesten connect with my oracle database.
i have more 100 data in my database. if i open with timesten there are 1 or more data miss.
example i open employees table from user HR. there are 1 missoing data. or i open costumers table from sh.
no data show in timesten.
why? and any suggestion?
thanks before

1. What kind of cache groups are youy using (READONLY, AWT, SWT etc.)?
2. When did you initially populate the cache groups from Oracle using LOAD CACHE GROUP?
3. Has the cache agent been running correctly since you first populated the cache groups?
4. Where have updates (insert/update/delete) been executed since you populated the cache groups? Oracle? TimesTen? Both?

JDBC Connection for Oracle

Hello Experts,
I'm having some trouble getting a JDBC connection to work correctly and I am in need of some advice.
Background:
I have setup a test Portal 7.00 SP14 with an Oracle 10.2.0.2.0 database on a Windows 2003 X64 server. The Portal system was up and running and connecting to a WAS6.20 systems. We do not have BI or XI in our landscape.
I needed to connect to an Oracle 10.2.0.3.0 database from visual composer to read some data from tables to do a proof of concept. From what I understand this connection will be a JDBC connection. I have setup a new system using the JDBC template, assisnged an alias, and entered the connection URL . I was unable to connect.
I read that I need to add the driver using Visual Composer. I did so with the following instructions:
Install JDBC Driver
Start the Visual Administrator
Logon at WebAS
Open: Server, Services, JDBC Connector, Drivers
Choose Create New Driver or DataSource on the toolbar
Specify an arbitrary name for your driver entry such as OracleDriver and click OK
Now search for the Oracle JDBC Driver JAR file on your local harddisk.
I restarted the Java instance with SMICM after completing this task Java will not start. Is there anyway to roll back that change to get Java back up and running?
Also is there a better way to go about making this oracle connection?
Best Regards,

Hi,
although [this guide|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/92d80512-0a01-0010-32a3-cd3735bd9275] is for Visual Composer I find it very helpful in setting up JDBC connections to databases. There is a very deltailed section about setting up a system to a MS SQL Server and the relevant data if you want to connect to Oracle:
4.2 BI JDBC Connector to Oracle
Located at:

I have installed on my pc Oracle 11g for windows 7 home edition 64 bit. Usually I use Navigator to develop
or manage my DB, Navaigator 3.0 can be use with a 64 bit client? I have some problem with my previous edition.I assume by "DB Navigator" you mean "SQL Developer" because that's what this forum's about. Or if it's the Jdeveloper
addon - go to the jdev fora.
What's stopping you going [url http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html]here and downloading the x86_64 version?

Create database connection for oracle ver.8.1.7.4 unsucessful

I trying create a database connection with jdeveloper 11g to db oracle ver.8.1.7.4, but the connection return error "Test failed: Unsupported Oracle database version". I selected connection type: "Oracle (JDBC)" and initially selected driver: "thin", after exchange to driver: "oci8", but return error: "Test failed: no ocijdbc11 in java.library.path". Created on menu > Tools > Preferences > JDBC driver options a new driver: "some.jdbc.Driver" pointing to Driver class: "some.jdbc.Driver", library: "oracle.jdbc.OracleDriver", class path: "c:\...\oracle\jdbc\lib\ojdbc14.jar".
Tried to create with this driver with the option "Generic JDBC" pointing to this driver created and using jdbc url: "jdbc:oracle:thin:@//255.255.255.255:1521/ServerId", but return error: "Test failed: Driver class not found. Verify the Driver location"
Now, i don´t know to do!!!

John,
i have the data corporate in this DB in this version. I have already tested with the oracle JDBC driver: "ojdbc14.jar" and works in the "Eclipse" IDE, but i want to use with jdev, understand? Can i test only with this jdbc driver if i set "generic JDBC"?, because if i set "oracle JDBC" this driver is pointing to oracle 11g driver. Is there a "step-by-step" to set this correct procedure? I cannot set "oracle JDBC" of list because the driver class is disabled.

Server manager not connecting for Oracle 8i

I am not able to connect to SVRMGR30 on Windows NT 4.0 ....ERROR 12560 - TNS error in Adaptor ...This is URGENT ...Can any1 help ?

There is an 8.1.7.4 patchset for Windows.
If you take a look at the Instant Client forum, there are some discussions on this where one of the Oracle product managers (Mr. Jue) has chimed in. At present, only connections to 8.1.7.4 and higher are supported. It is expected that the first 10g patchset will fix this bug and allow connections to 8.1.7.0 and above databases.

ODBC Connectivity for Oracle 8.1.6

Hi, I am trying to find odbc.ini file so as to connect using ODBC, but am not being successful. Can anybody help?

Are you trying to connect to a Linux database from a Windows client, or are you trying to connect from a Linux client? Which ODBC driver are you using?
