JRA connection for Basque Language
We are having problem in setting up the JRA connection for Basque language(eu), It throws up the exception in java code as "JCO_ERROR_LOGON_FAILURE - Install the language pack ".
We can logon on to SAP back end with language code "eu",
We are using NW 7.01 and as per the CE 7.3 doc, http://help.sap.com/saphelp_nw73/helpdata/en/48/883f9f77323cb8e10000000a42189d/frameset.htm, it maps to the Logon language code. Assuming the same documentation also holds for NW 7.01.
Very much appreciated, if any inputs to the above issue.
Thanks & Regds,
JC
Hi,
I just read about JRA and found the following facts.
'The SAP Java Resource Adapter (SAP JRA) is a J2EE -compatible connector for SAP systems. It enables the integration of SAP systems with J2EE application servers. The SAP JRA implements the standard J2EE interfaces for the SAP Java Connector (SAP JCo), thus simplifying communication between heterogeneous, distributed J2EE landscapes and SAP.
You can use the SAP JRA to call remote functions of an SAP system by executing RFC calls via TCP/IP.'
So I believe since its just an add-on like thing which connects to the SAP system via SAP JCO you shouldn't worry about connecting to message server.
Since while creating a JCO connection you can define whether it should be a load-balanced or not.
Check this link.
http://help.sap.com/saphelp_erp2004/helpdata/en/3a/3b1b40fcdd8f5ce10000000a155106/frameset.htm
another example would be found here...
http://help.sap.com/saphelp_erp2004/helpdata/en/25/19e7752be1c8459258a072d87e3a34/frameset.htm
hope that clears your doubt.

i cannot open itunes on my windows lap top. am getting error message saying it is not currently localised for this language. run english version'. I am cofused as I have been using itunes on my lap top successfully for last 2 years?! Any ideas. jac
Let's try a repair install of iTunes.
Restart the PC first.
If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair".
If you're using XP, head into your Add or Remove Programs control panel, select "iTunes", and click "Change". Select "Repair" and click "Next" as per the following screenshot:
Can you launch your iTunes now? -
Oracle 9i Support for multi language is not working.. Giving question mark
HI,
We have an application which uses oracle 9i as the database. Riight now we are supporting only english and there is a requirement to support multiple languages like korean, chineese and japaneese.
But we are planning to migrate one part of the application to support multi languages. Means it may affect around 10 tables but with huge data. Totally we have around 100 tables.
How to enable the database for supporting multiple langugages.?
Is there any way to enable only the few tables supporting multiple languages. Because if we change the database level parameters for supporting languages, we may need to migrate entire tables. this will be a huge task.
Even if want to set the parameters for supporting multiple languages.. how to set it. Is it possible set it in the existing database or do we need to re-create the table with these prameters.
I have read in some documentation, that we can create table columns with nVarchar2 for supporting multi languages. I have created it. but if i copy some other language characters into those columns, it is giving question mark.
Is it possible to do search using text in native langugage like chineese..
Could somebody guide me on the above clarificationa and what would be the best approach..
Thanks in advance

CHARSET for Korean language to open Korean .wft files in workflow.
Hi,
I want to open Korean .wft files in oracle workflow builder.
For that, I had given 'KOREAN_KOREA.KO16KSC5601' (and also 'KO16KSCCS' as charset) as the NLS_LANG value in the window registry but I am getting following error once I logged in to database using workflow builder:
1300: Could not load.
1114: Could not load from database.
1101: Could not load item types from database. FILTER=%
333: Could not set item type properties for 'FPAPJP'.
332: 'SET' validation failed for item type 'FPAPJP'.
306: Invalid display name 'Project Portfolio Analysis '.
203: Value contains leading or trailing spaces.
When I tried with 'KO16DBCS' charset, I am getting following error:
1700: Could not connect with username/password 'apps/apps@cxlv1' ('ORA-01017: ‰•¥“‰„@¤¢…™•”…a—¢¢¦–™„^@“–‡–•@„…•‰…„
though I am using the same username/password and tnsname that I am using to connect english and japanese .wft files.
Please share with me the correct charset for korean language to be able to work with workflow builder.
Thanks,
Sumit

It didn't work..When I am giving AMERICAN_AMERICA.KO16KSC5601 as value for NLS_LANG, workflow builder is fetching wft only in American English !..
Any other clue!! -
Not able to connect for English [GB]
Hi All,
Our MDM repository set for three languages English [US],English [GB] and German [DE]. We are able to connect to repositoty for all the 3 languages through MDM client.

String language = "Spanish [MX]";
mdmBridge.SetCodeRegion("English [US]"); mdmBridge.Login(server,port,user,password,language);
As you can see, I always use CodeRegion (English [US]), how ever, the language and localization goes in Spanish [MX] as set on the language property String.
I hope this helps

How do I set miminum # of connections for pool with Oracle and Tomcat?
Hi,
I can't seem to find any attribute to initialize the number of connections for my connection pool. Here is my current context.xml file under my /App1 directory:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1" />
</Context>
I've been googling and reading forums, but haven't found a way to establish the minimum number of connections. I've tried all sorts of parameters like InitialLimit, MinLimit, MinActive, etc, with no success.
Here is some sample code that I am testing:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xxx");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
rst = stmt.executeQuery("SELECT username, server from v$session where username is not null");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; Server: " + rst.getString(2);
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
I'm using a utility to repeatedly call a JSP page that uses this class and displays the message variable. This utility allows me to specify the number of concurrent web requests and an overall number of requests to try. While that is running, I look at V$SESSION in Oracle and occassionaly, I will see a brief entry for app1 or adavey depending on the timing of my query and how far along the code has processed in this example. So it seems that I am only using one connection at a time and not a true connection pool.
Is it possible that I need to use the oci driver instead of the thin driver? I've looked at the javadoc for oci and the OCIConnectionPool has a setPoolConfig method to set initial, min and max connections. However, it appears that this can only be set via Java code and not as a parameter in my context.xml resource file. If I have to set it each time I get a database connection, it seems like it sort of defeats the purpose of having Tomcat maintain the connection pool for me and that I need to implement my own connection pool. I'm a newbie to this technology so I really don't want to go this route.
Any advice on setting up a proper connection pool that works with Tomcat and Oracle proxy sessions would be greatly appreciated.
Thanks,
AlanWell I did some more experiments and I am able to at least create a connection pool within my example code:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
boolean cache_enabled = ds.getConnectionCachingEnabled();
if (!cache_enabled){
ds.setConnectionCachingEnabled(true);
Properties cacheProps = new Properties();
cacheProps.put("InitialLimit","5");
cacheProps.put("MinLimit","5");
cacheProps.put("MaxLimit","10");
ds.setConnectionCacheProperties(cacheProps);
conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xyz");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
//rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
rst = stmt.executeQuery("SELECT user, SYS_CONTEXT ('USERENV', 'SESSION_USER') from dual");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; sys_context: " + rst.getString(2);
message += "; Was cache enabled?: " + cache_enabled;
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(OracleConnection.PROXY_SESSION); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
In my context.xml file, I tried to specify the same Connection Cache Properties as attributes, but no luck:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1"
ConnectionCachingEnabled="1" MinLimit="5" MaxLimit="20"/>
</Context>
These attributes seemed to have no effect:
ConnectionCachingEnabled="1" ; also tried "true"
MinLimit="5"
MaxLimit="20"
So basically if I could find some way to get these attributes set within the context.xml file instead of my code, I would be a happy developer :-)
Oh well, it's almost Miller time here on the east coast. Maybe a few beers will help me find the solution I'm looking for. -
In need of help figuring this phone stuff out! I am trying to get all the apps from my husbands old phone to his new one. I have already backed up the old phone and got everything onto iTunes, but every time I plug the new iPhone 5s into my computer it says that the version of iTunes is not correctly localized for this language and asks for me to run the English version. I have no idea how to do that? Please help.

my laptop will not open iTunes, as it just says 'This version of iTunes has not been correctly localised for this language. Please run the English version'. I have not synconised my iPhone 5S or iPad 2 with iTunes for well over a year. I noticed the music which had previously been put into iTunes has dissappeared from my phone and iPad. I also want to remove some movies from my iPad and iPhone and there is no way I can do this without being able to manually sync with the Laptop which is running windows 7. Has anyone else come across this and please can you help? I am no expert in fact I know very little about the Laptop, it is my Husbands baby but he doesn't understand anything to do with Apple including iTunes. I will need any advise explained step by step please.
Hi Shelady,
Try downloading and reinstalling the latest version of iTunes from the first link below. If that doesn't do it, the suggestions in the second article should resolve the installation issue.

Performance degradation using Jolt ASP Connectivity for TUXEDO
We have a customer that uses Jolt ASP Connectivity for TUXEDO and is suffering
from a severe performance degradation over time.
Initial response times are fine (1 s.), but they tend to increase to 3 minutes
after some time (well, eh, a day or so).
Data:
- TUXEDO 7.1
- Jolt 1.2.1
- Relatively recent rolling patch installed (so no there are probably no JSH performance
issues and memory leaks as fixed in earlier patches)
The ULOG shows that during the night the JSH instances notice a timeout on behalf
of the client connection and do a forced shutdown of the client:
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1185: "INFO: Userid:
[ZZ_Webpol], Clientid: [AP_WEBSRV3] timed out due to inactivity"
040911.csu013.cs.kadaster.nl!JSH.234333.1.-2: JOLT_CAT:1198: "WARN: Forced
shutdown of client; user name 'ZZ_Webpol'; client name 'AP_WEBSRV3'"
This happens every 10 minutes as per configuration of the JSL (-T flag).
The customer "solved" the problem for the time being by increasing the connection
pool size on the IIS web server.
However, they didn't find a "smoking gun" - no definite cause for the problem.
So, it is debatable whether their "solution" suffices.
It is my suspicion the problem might be located in the Jolt ASP classes running
on the IIS.
Maybe the connection pool somehow loses connections over time, causing subsequent
users having to queue before they get served (although an exception should be
raised if no connections are available).
However, there's no documentation on the functioning of the connection pool for
Jolt ASP.
My questions:
1) What's the algorithm used for managing connections with Jolt ASP for TUXEDO?
2) If connections are terminated by a JSH, will a new connection be established
from the web server automatically? (this is especially interesting, because the
connection policy can be configured in the JSL CLOPT, but there's no info on how
this should be handled/configured by Jolt ASP connectivity for TUXEDO)
Regards,
Winfried ScheuldermanHi,
For ASP connectivity I would suggest looking at the .Net client facility provided in Tuxedo 9.1 and later.

We have a new iMac 2.9ghz and are running an airport extreme set up in house with several express entenders. The problem is that our son is streaming netflix and doing on line gaming and hogging all the band width. Time Warner tech suggested a hard wired ethernet connection to computer base sattion next to computer so that it can have direct conenction to internet. After much fishing of wire the connection worked great, but the wifi connection for the house is gone. I unplugged the ethernet connection and everything is fine. I read the articles about adjusting network preferences, but the issue seems to be in the extreme not in the computer. the connection goes from cable modem to extreme, from extreme to house and to hard wired conenction to other computer. Do we need a splitter before the extreme?
No. Something else is going on.
Your son may be hogging all the bandwidth but your wireless network should never simply disappear. Moreover, if your son isn't doing anything the available bandwidth for other devices should remain unaffected.
I suspect that something is miswired, and from what you describe I suspect that link is between the Extreme and the "other computer".
The way to accomplish what you propose is
Modem > Ethernet cable to Extreme's WAN port
Extreme's LAN ports > wired Ethernet devices.
There should be nothing but an Ethernet cable linking an Extreme LAN port and any other wired device. If you run out of available LAN ports on the Extreme, you need to by an "Ethernet switch" - they are not expensive, but don't call it a "splitter" or you will only confuse yourself. The switch would be connected to one of the Extreme's LAN ports, and you would connect additional devices to it. You can also use one of your Expresses for that purpose, assuming it is the current generation model with two Ethernet ports. -
Auto_lexer (stemming) not working for other languages(other than english)
Hi All,
We are planning to use AUTO_LEXER instead of MULTI_LEXER and observed that stemming is not working for German where as it is working for English when I use AUTO_LEXER. I even used query templates but of no use.
But when i use MULTI_LEXER, creating sub lexers for German and Enlgish, Stemming is working for German also after changing the session language and setting stemmer of wod list to German (Which is expected).
Following is the code for AUTO_LEXER creation:
CREATE TABLE test_auto_lexer(pkey NUMBER(5,0),
lang_index VARCHAR2(3),
content_text CLOB,
CONSTRAINT test_auto_lexer_pk primary key (pkey))
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (1,'eng','I drive a bike')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (2,'eng','I drove a bike')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (3,'eng','I have driven a bike')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (4,'eng','Just check for other things')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (5,'eng','always drive a car')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (6,'eng','it is nothing')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (7,'ger','Ich fahre ein Fahrrad')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (8,'ger','Ich fuhr ein Fahrrad')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (9,'ger','Ich habe ein Fahrrad gefahren')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (10,'ger','Aktivieren Sie einfach für andere Dinge')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (11,'ger','immer Auto fahren')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (12,'ger','es ist nichts')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (13,'ger','sprechen')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (14,'ger','sprach')
INSERT INTO test_auto_lexer(pkey,lang_index,content_text)

INSERT INTO test_auto_lexer(pkey,lang_index,content_text)

INSERT INTO test_auto_lexer(pkey,lang_index,content_text)

INSERT INTO test_auto_lexer(pkey,lang_index,content_text)
VALUES (18,'ger','tales')
BEGIN

END;
BEGIN
ctx_ddl.set_attribute('auto_lexer1','index_stems','yes');
END;
BEGIN
ctx_ddl.set_attribute('auto_lexer1','language','danish english german');
END;
BEGIN
ctx_ddl.set_attribute('auto_lexer1','alternate_spelling','german');
END;
CREATE INDEX test_auto_lexer_ix1
ON test_auto_lexer(content_text)
INDEXTYPE IS ctxsys.context
PARAMETERS ('datastore ctxsys.direct_datastore filter ctxsys.null_filter lexer auto_lexer1')
select to_char(content_Text) from test_auto_lexer where contains(content_text,
'<query>
<textquery lang="ger" grammar="context">
$fahren
</textquery>
<score datatype="integer"/>
</query>') > 0
this doesnt work even after changing the session language. My default Sesson language is AMERICAN.
Could any one help me with this, in case I am missing something here. I would be really thankful.

According to the online documentation, Oracle only supports stemming for English, Dutch, French, German, Italian, Spanish, and Japanese. Oracle does not support Russian stemming, although you may have gotten some accidental results, due to identifying it as a different language and applying stemming rules for that language. The following manual sections show the languages available for the index_stems attribute of the basic_lexer and stemmer attribute of the basic_wordlist:
Basic_lexer attributes:
http://docs.oracle.com/cd/E11882_01/text.112/e24436/cdatadic.htm#CIHHBAAD
Basic_wordlist attributes:
http://docs.oracle.com/cd/E11882_01/text.112/e24436/cdatadic.htm#g1019326
Also, please see the following note:
Features not available in 11.2.0.3:
http://docs.oracle.com/cd/E11882_01/readmes.112/e22488/toc.htm#BABDGGDB
"Certain Oracle Text functionality based on third-party technologies, including AUTO_LEXER and CTX_ENTITY, have been disabled in this release (reference Bug 12618046). For BASIC_LEXER, the usage of the INDEX_STEMS attribute values that depend on third-party technologies, is also affected. If this impacts an existing application, contact Oracle Support Services for guidance."
Also, the auto_lexer has been replaced by the world_lexer, which only has one attribute:
http://docs.oracle.com/cd/E11882_01/text.112/e24436/cdatadic.htm#BHCJEGFJ
I don't work for Oracle, so I don't know why they do things the way they do.
So, you need to stick with the basic_wordlist for stemming, not the lexers. However, you may get better performance by combining the multi_lexer with the basic_wordlist, as the multi_lexer eliminates time spent on automatic language detection. But, you need to remember not to use the index_stems with your lexer, since it will conflict with the wordlist. I am not experiencing any time problems as you have. Please see the demo below. I have provided the whole script below that, so that you can reproduce it on your system. If you still have problems, then it may be due to differences in versions.
