Oracle edition for Cache connect

hi,
Is there a limitation for the Oracle edition to be used with cache connect.
Can we use all of Oracle XE to Standard Edition One to Enterprise edition or just only
Enterprise edition?
Thanks.

Cache Connect works with all editions: XE, SE, EE etc.

Done.

Solved the problem myself. Had to stop and restart cache agent using the timesten software installation account and not as root.
Documentation is not clear as to what happens when you install timesten using a "non root" account. Per documentation, we have to run setuproot script to create startup / stop scripts under init directory. With a non-root installation these scripts are created and on reboot agent process inherits the root account privs. This is a problem. For a non-root install the agent process should inherit the privs of the account that performed the installation and not root's.
May be a documentation correction is needed here.

Please recommend solutions for Cache Connect and ?

---> Solution I
2 servers create Cache Connect to RDBMS
---> Solution II
1 server create Cache Connect to RDBMS and create active standby pair with another server

Hi,
If you only need READONLY caching in TimesTen and all updates will be made in Oracle then you have two main options:
Multiple READONLY Caches
For this you have one or more separate TimesTen caches each with a READONLY cache group defined against the oracle DBMS. Each cache can cache different tables/data or they can can cache the same tables/data as required.
This architecture is very flexible (adding or removing TimesTen servers is very simple) and very scalable. It also provides very good HA; if one cache is down applications can just access a different cache.
However, due to the asynchronous, time based nature of the refresh from Oracle to Timesten at any moment in times the data in all the caches may not be 100% consistent with each other or Oracle.
By this I mean the following:
- Assume that you have 2 (or more) READONLY caches caching the same data from Oracle, with an AUTOREFRESH interval of T1
- At some time, T2, you update, in Oracle, one of the rows cached by the caches.
- At some later time, T3, you query the updated row via both caches
If (T3 - T2) < T1 then the values returned by your query may differ between the caches (depending on where exactly they are in the autorefresh interval when the update is done).
Active/Standby pair using 2-SAFE replication with READONLY cache group and optional read-only subscribers
With this architecture you define a TimesTen Active/Standby replicated pair using 2-safe replication and containing the READONLY cache group. 'Scale out' is accomplished in one of three ways:
1. Adding further A/S pairs with a READONLY cache group
2. Adding read-only subscriber datastores to the original A/S pair
3. A mixture of (1) and (2)
The main advantages of this architecture are as follows:
1. When 2-Safe is used within the A/S pair, queries to either cache will always return consistent results (i.e. the consistency issue that I described for the first scenario does not exist in this configuration). However, threr can still be inconsitencies in results between the A/S pair and any readonly subscribers (since the replication to them is asynchronous) but given the high performance of TimesTen replication the latency between a change appearing at the A/S pair and the readonly subscribers will typically be a few ms rather than potentially several seconds for the multiple-cache scenario.
2. The loading on the central Oracle DBMS arising from AuTOREFRESH processing is reduced compared to the multiple-cache scenario. The difference in loading between this solution and the multiple cache solution will be larger as more TT servers are deployed.
It should be noted that the operational management of this solution is a little more complex than for the first scenario since the A/S pair must be monitored and a 'failover' trigerred if there is some fauilure within the pair.
Hope that helps a little.

Using Oracle Wallet for Java connection

Hi,
Can anyone tell me how to acces the Oracle wallet from my Java application without using the thin or oci drivers?

No answer was found for this, we ended up using an OCI driver for the connection to the wallet. Code (in java) was as follows for reference:#
private static Connection walletconn() throws Exception{
String url = "jdbc:oracle:oci:/@DATABASE";
OracleDataSource ods = new OracleDataSource();
ods.setURL(url);
Connection conn = ods.getConnection();
return connl;

I have tried for several days but to no results. Please advise how to solve the problem. Thank you very much

Dear all,
I have found a solution for this error. We could use Oracle 10.2 g on HP-UX v11.31. However, when you do the installation, command will be: "./runInstaller -ignoreSysPrereqs".
The steps to install oracle client are following ( $ORACLE_CLIENT_HOME):
1) su - oracle
2) Download Oracle 10.2g HP-UX Itanium "10gr2_client_hpi.zip"
3) unzip the file : "jar xvf 10gr2_client_hpi.zip " . The new folder name "client"
4) cd client; ./runInstaller -ignoreSysPrereqs
After that, you need to remove the $ORACLE_HOME/lib/libclntsh.so and link to new file
5) rm $ORACLE_HOME/lib/libclntsh.so
6) ln -s $ORACLE_CLIENT_HOME/lib/libclntsh.so.10.1 $ORACLE_HOME/lib/libclntsh.so
7) export LD_LIBRARY_PATH=$ORACLE_CLIENT_HOME/lib:$TIMESTEN_HOME/lib:$ORACLE_HOME/lib
8) export PATH=$ORACLE_CLIENT_HOME/bin:$PATH
Then you need to restart the TimesTen Daemon so that it could get the new system parameters
9) ttDaemonAdmin -restart
if you do not restart the TimesTen Daemon, you could get the error:
Command> call ttCacheStart;
10024: Could not start cache agent for the requested data store. Could not initialize OCI function pointers. Error: none
The command failed.
And finally, the CacheConnect is up

Cache Connect Oracle Database Support

What versions of the 10g Oracle Database server are supported by Cache Connect for TimeTen 7.0.4 & 7.0.5?
The TimesTen 7.0.4 & 7.0.5 Installation Guide lists that 10gR1 & 10gR2 are supported.
What about 10gR3 & 10gR4 for TimesTen 7.0.4 & 7.0.5?
Thanks.

Brian,
There are no 10gR3 and 10gR4 for the Oracle Database.
- 10gR1 = 10.1.0.x
- 10gR2 = 10.2.0.y
The latest 10gR2 release number is 10.2.0.4 and is available on Linux and a number of other platforms.
Both TimesTen 7.0.4 and 7.0.5 support 10.2.0.4 and this is the recommended client version for Cache Connect; the reason is that we have found Oracle OCI client side issues with pre-10.2.0.4 releases and they are fixed in 10.2.0.4.

Cache Connect passthrough

I have a 32bit Oracle client installed on Solarus 8 server. Have DSN defined to passthrough to backend oracle database. When I try to select from the backend database I get the following 5102 error
5102: Cannot load backend library 'libclntsh.so' for Cache Connect. OS error message 'ld.so.1: ttIsqlCmd: fatal: /oracle/product/9.2.0/lib/libclntsh.so: wrong ELF class: ELFCLASS32'. See TimesTen Reference Guide for possible causes.
LD_LIBRARY_PATH has $ORACLE_HOME/lib and libclntsh.so exists although it is a link to libclntsh.so.9.0

Found the problem - Loaded the 64bit version of TimesTen vs the 32bit version. I was sure I loaded the 32bit version. Oh well - Reinstall time

TimesTen Cache Connect support for Oracle 11g

The latest 7.0.5 readme mentioned that "Oracle Release 11gR1 is supported with TimesTen Cache Connect to Oracle on Linux x86 32-bit and 64-bit platforms, and on Windows 32-bit."
What about Solaris 10? It looks like on Solaris 10 only Oracle 10gR2 being supported. What is so specific about Oracle 11?
Thank you,
Alex

TimesTen 7.0.5 can be used to cache data from different versions of Oracle database.
The reason why the support for Solaris, AIX, and HP-UX were not at the same time as the Linux platform was because Oracle database 11g was not available on those platforms initially. So TimesTen 7.0.5 was certified to support only the ones available first, and support for other platforms was added as 11g became available on those platforms. It was just timing of the certification, code base is the same.

Connect from Windows Client to Oracle 10g for Windows 64-bit

Have an environment currently running Oracle 10g 32-bit on Windows 2000 Standard, and need to migrate to Oracle 10g 64-bit for Windows. Users connect to the 10g 32-bit database using the Oracle Client for Windows 10g loaded on remote PC's. If we migrate to the Oracle 10g 64-bit on Windows 2003 Server Enteprise Edition 64-bit, what type of client do I have to install on the PC's to access the Oracle 10g 64-bit database?
Any ehlp/insight will be greatly appreciated.
Eduardo in Michigan

In addition to install 32-bit Oracle client to 32-bit Windows OS, you need to know whether your application is compiled to run in 32-bit or 64-bit.
This is critical because 32-bit application can not see 64-bit Oracle ODBC and OLE DB provider.
For example, MS SQL Server 2005 uses 32-bit DTS, and SSIS, which needs 32-bit Oracle client
If you don't know, get a copy of both 32-bit and 64-bit Oracle client, and try one-by-one to know for sure. Please be aware that if regsvr32.exe in the Windows has been overwritten by older software installation, it won't register some DLL properly, and Oracle ODBC, or OLE DB won't show up as well

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?

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

How do I check the Oracle enviornment variables for a connection?

I am using Oracle JDBC 10.2.0.4 and trying to output the Oracle enviornment variables for a connection.
I am trying to determine if the values output from sqlplus from the following two SQL select statements are different in the connection object:
SELECT * from NLS_SESSION_PARAMETERS order by 1;
NLS_CALENDAR GREGORIAN
NLS_COMP BINARY
NLS_CURRENCY $
NLS_DATE_FORMAT MM/DD/YYYY HH24:MI:SS
NLS_DATE_LANGUAGE AMERICAN
NLS_DUAL_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_LANGUAGE AMERICAN
NLS_LENGTH_SEMANTICS BYTE
NLS_NCHAR_CONV_EXCP FALSE
NLS_NUMERIC_CHARACTERS .,
NLS_SORT BINARY
NLS_TERRITORY AMERICA
NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR
NLS_TIME_FORMAT HH.MI.SSXFF AM
NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR
SELECT sys_context('userenv','language') from dual;
AMERICAN_AMERICA.WE8ISO8859P1
Is there a way to do this in the API or do I just need to run the SQL statements in a Class and output the values to a log?
Thanks,
--Todd

So try it.
Create a connection with no settings.
Alter all of the (session only)
Query again and see.
Either the query will return the altered values or it won't.
