TimesTen In-Memory :: Cannot Connect To Server With Ttisqlcs / Failed To Retrieve IP Address Of The System
Nov 16, 2013
I installed timesten server and client on different machines in LAN, but with the same user and group - ttadmin:ttgroup When I tried to connect to server with ttisqlcs -connStr "DSN=sampleCS"The output gave me error messages as below connect "DSN=sampleCS";S1000: Failed to retrieve IP address of the system. System error: -2The command failed.Done. The related part in sys.ttconnect.ini is set as below
[192.168.0.206]Description=TimesTen ServerNetwork_Address=192.168.0.206TCP_PORT=53397
And the
sys.odbc.ini [ODBC Data Sources]sampleCS=TimesTen 11.2.2 Client Driver [sampleCS]TTC_SERVER=192.168.0.206TTC_SERVER_DSN=nredb_ds
What does it mean by "retrieve IP" ?Does it try to resolve IP by the hostname even when I already gave it the ip address?By the way I can ping 192.168.0.206 and telnet at port 53397 with no problem.

I would like to have a query which should fetch previous day records from column which is having timestamp data type.
select mdn from user_table where updatetimestamp > trunc(sysdate) - INTErVAL '24' HOUR;
But this gives output not for previous day, but all records which are 24 hrs less than current day. How to get records for previous day based on column having timestamp data type.

I have the following setup
SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?

Can i know the internal process of initialization of DB into memory in timesten , when a new connection is establishing? Will timesten create tables and indexes in RAM when first connection is established if the RAM policy is default?
want to know the internal functional flow of timesten when any command is fired against it.

As per my understanding , Timesten or IMDB Cache can be connected through DSN by any external client. Want to know whether Radware can be integrated with Timesten or IMDB Cache.

I connection to TimesTen as follow:
String url = "jdbc:timesten:direct:dsn=my_ttdb";
String username = "ADMINISTRATOR";
String password = "";
Connection connection = DriverManager.getConnection(TestTT.url, TestTT.username, TestTT.password);
I wonder if this JDBC Connection is a TCP/IP connection on the backend? If this is not a TCP/IP connection, how can I make a connection with TimesTen via TCP/IP protocol?
dsn:my_ttdb configuration likes:
[my_ttdb]
Driver=/home/tttest/TimesTen/tt1122/lib/libtten.so

,Im having following replication scheme: M1,M2 and M3 are multimaster replicated datastores.These three datastores will replicate its data to a node which is going to act as a Propagator.The Propagator will then replicate data to a set of subscribers. Question:-------------
Can we configure the Propagator to be redundant.ie, can we configure an additional propagator which will act as redundant and replicate to the same set of subscribers?

We cache oracle 11g2 data in timesten 11.2.2.5.0 ( IMDB ) We can't find any trigonometric functions like cos(x), sin(x) or so in timesten. Does that means timesten doesn't support trigonometric functions?

The document says "Propagators are also useful for distributing replication loads in configurations that involve a master database that must replicate to a large number of subscribers".
Link [URL]........
My question is how do we define this " large number ". Is 5 a large number or 10 a large number ? I've a bidirectional legacy replication scheme wherein a node replicates to 10 other nodes. Should i introduce Propagator between these nodes.

We have been using XLA to capture events on TimesTen for a while now without any issues. We were on TimesTen 7.0.5 and then moved to 11.2.2.3.0 and now 11.2.2.4.0. The XLA processes used Java 6 64 bit and works well with TimesTen versions 11.2.2.4.0 - 64 bit and 11.2.2.3.0 - 64 bit, without any issues.
However, we recently upgraded to Java 7 64 bit both during build time of our XLA processes as well during runtime. The problem we see now is that XLA process upon startup processes events for a while and then after that doesnt receive any events. The process doesn't throw any errors/exceptions. If we restart the XLA process, all the unprocessed events are received and then it behaves normally for a while after which it fails to receive any further events.
Is there any issue with Java 7 64 bit and the TimesTen XLA API? I read the TimesTen 11.2.2.4.0 manual and it says that Java 7 and the ttjdbc7.jar have been certified to work well. Was just wondering if there were any other issues.
In addition, to debug the problem, we ran XLA on a single node and on a two safe setup. The same observations are noted. On Java 6, the process runs just fine capturing all events without any issues, but with Java 7, the issues persist.
In addition, we are only performing updates/inserts on to TimesTen, no delete actions. The OS on which TimesTen's and XLA runs is Red Hat Enterprise Linux Server release 5.7 (Tikanga).

we want to truncate a oracle Table in the Oracle DB. After the truncate the fact table will be loaded again. After the new load in the fact table we want to tell the times ten db to refresh the cache table. The cache Table is a user owned read-only cache group with no autorefresh. We want to tell times ten in a PL/SQL Block from Oracle DB that starts the refresh from the cache group in times ten. The refresh should not be a autorefresh because the refresh should only start if the fact table will new loaded after the truncate.

I have already created an active standby pair(without cache group) and managed by Oracle Clusterware and it work fine.
Now ,I create another DSN and I also want to create another active standby pair on the same 2 hosts.
I try to setup and reference this setting:
[URL]...
But I get error message in ttcwmessage :
TT17013 The default hostname cannot be set to host_name because a local host of host_name is currently in use
Is it possible that I can create more than one A/S pair(with different DSN) ? Or any other solution? !

For applications and Timesten databases on the same server we can use direct model to gain the base performance. But I want to know that how big heap size of JVM to be set for my java application when enabling direct model?
Does my application need more head memory when direct model than other local communication protocols, such as Unix domain socket or IPC? Supposing my Timesten database takes 12GB memory from OS, does it mean I need specify the same size for JVM heap(-Xmx12G)?

try to evaluate it as IMDB cache.I am facing this error repeatedly. I have increased perm size from 6.25 GB to 10 GB.After inserting about 460.000 rows I get the error again. Is it possible that 460.000 rows need 3.75 GB space?
In Oracle database these rows occupy about 200 MB space.

I have a problem with executing oracleCommand.ExecuteReader() method. Whatever I try it always returns null and it won't create OracleData reader object. I'm using ODAC 1120320_x64 for .net 4.0 and timesten112241.win64. Don't sure what to do. Debugger is showing strange thing in OracleConnection object : ConnectionState = Closed, but output of ttStatus shows connection to TimesTen data store and ExecuteNonQuery() command works just fine with or without (in or out) parameters. But when I try to execute some query with multile output such as select *, I can't get any result.
I also have a strange problem with connection.Open() When I execute Open() i throws AccessViolationException that can be handled with [Handle ProcessCorruptedStateExceptions] attribute, but connection is established after that and my application works fine until I try to instance OracleDataReader object.
Here is the code:
OracleCommand select = null;
OracleDataReader reader = null;
select = new OracleCommand(selectStmt, connection);
select.CommandType = CommandType.Text;
try
{
reader = select.ExecuteReader(); // this line throws NullReferenceException
if (reader.HasRows)
{
[code]....
Just to mention, I tried it with different queries (pl/sql, plane sql, stored procedure) and all of them works fine in SQL Developer, but not in app.

how to connect to Oracle to retrieve data using SQL language. I've started with a new company which is pretty much a sink or swim type of environment meaning you're an idiot if you don't figure it out on your own. I was told that we use Toad for Oracle 10g. I was given a server name; location and an .ora file named tnsnames that was given to me but I have no clue what to do with. I've come from companies where this was already setup. You just go into access to retrieve the data.
II have totally hit a brick wall with all the other roadblocks I encounter and all researched out. Where I can get step by step instructions on how to connect to start sql in Toad/Oracle?
