EA2 - EA1 - Connection interface is unavailable

1) Create a connection
The action on File->New->Database connections->NOTHING ( the window is closed without an action).
2) I had the same problem on EA1 after deleting of an existing connection
3) I've just reinstalled JVM, JDK and EA2 with the same results.
4) Several menu are misplaced (for example "source")
Thank you

Edited by: zep111 on Nov 10, 2009 2:49 PM

Reinstalled :
1) Deleted the old sql Developer folder
2) Deleted all the previous settings folder
3) New Unzip ot the latest EA2 in a different folder
Result : it's OK .
This solve the issue in the EA2 new installation, but that was done to get around the same problem I had on EA1 after deleting a connection.
I worked on EA1 for several days without connection problems until I deleted my connection!
But now I've already deleted EA1 and I can't show you anything on the console related to that issue.
Anyway, now I'm on my way again and I'll use your instructions next time I'll have an error like the one I've had in EA1 this morning.
Thank you.

Help! with creating a J2ME program using the http connectivity interface

So this is what I have to do using the http connectivity interface:
1.Creating two threads – one for communication (receiving and sending) and the other (main) thread will be for interaction with the user.
2.The main thread will make use of three midlet forms. The first form will ask for web page address (URL) and separately for a delimiter which will separate the words in the URL document, the third form will display the ratio of all symbols on the page and the number of occurrences of the delimiter specified
3.The second thread should perform http connectivity to the WWW, utilise the web page address supplied and connect to the appropriate web page and read its content, count all symbols on the chosen page, count the number of occurrences of the delimiter given as user input on the same form as the web page address, calculate the ratio between the two and pass this information to the first thread to display.
I have many questions but my main concerns are:
*1. How to communicate using HTTP interface within a thread*
*2. What is a delimiter in the context above and how should it be implemented*
I've been thrown in at the deep end with little programming experience with this assignment. If anyone can share a similar example or answer my concerns I'd be more than happy.
Thanks in advance.

hi thanks for the response.
As I said I have coded in other languages before, but this is a new for me in java. I needed to get it working quickley. Now I can clean up.
I will have a look at method and see how I get on.
ANy similiar examples would be great.
Thanks.I can certainly give you a similar example.
Say you have code such as this:
int a = 10, b = 11;
int temp = 1;
for(int i = 2; i < a; ++i) {
temp *= i;
System.out.println(a + " factorial is " + temp);
temp = 1;
for(int i = 2; i < b; ++i) {
temp *= i;
System.out.println(b + " factorial is " + temp);Each section of code takes the factorial of the current variable an outputs it. The factorial code can be placed within a method to be called more easily, as such:
public void factorial(int num) {
int temp = 1;
for(int i = 2; i < num; ++i) {
temp *= i
System.out.println(num + " factorial is " + temp);
}Then, whenever you need to call it, you can just do so:
int a=10,b=11,c=12;
factorial(a);
factorial(b);
factorial(c);

Agent Connection to Instance Unavailable

Win2k3 64 bit
Oracle Database 10g Release 10.2.0.5.0 - 64bit Production
I brought up a new 10.2.0.5.0 db on Win2k3 64 bit server. Everything is working fine, at least it seems so. This server has been running for 2 months now and this issue kept coming up in the last 2 months.
Database Instance status is Open
Listener status is Up
General status is Up
Agent Connection to Instance is Unavailable.
Users SYSMAN and DBSNMP are OPEN.
This will be the 3rd time in the last 2 months if I rebuild EMCA again.
Is anyone else besides me experiencing this issue? Why is this happening and how do I fix it permanently?

1.Post the output of :
SQL> select global_name from global_name;
SQL> show parameter db_domain;
2.lsnrctl service
3.lsnrctl status
4.Did you change the hostname?
5.Is timezon of agent and console the same?
6.In the file $AGENT_HOME/sysman/config/emd.properties, make sure the following parameters are correct. Obtain the values from $OMS_HOME/sysman/config/emd.properties
1. REPOSITORY_URL
2. emdWalletSrcUrl
3. emdWalletDest (ensure that this destination is present on your management server).
7.If you're using Data Guard in 11g for primary/standby configuration, you may want to check the Data Guard configuration status. With this type of error, it's usually caused by the database parameter setting for log archive that differs with the Data Guard config for log transport and apply. For example, if the local archive log destination on the primary is pointing to the standby site instead of local archive directory (or local flash_recovery_area), The GC will generate this error and blank out the options for database instance in GC.
I am just pasting the above texts from different forum link when I just said "Agent Connection to Instance Unavailable" to google.

Implementing Connection interface

I am implementing my own Connection interface.
Most of my methods are implemented by delegating a "real" Connection object I receive from the JDBC driver, except the "close()" method where I instead of closing the connection return it back to the pool that I created.
Now when I do the following:
ConnectionPoolManager poolMan = ConnectionPoolManager.getInstance();
con = poolMan.getConnection(SI.getDataSourceName());
I get the connection and I can close it using
con.close();
My log4j successfuly reports that connection was returned to the pool.
Now the interesting part.
If I create a statement and the resultset from it and then close the connection using the following code:
st = con.createStatement(resultSetType, resultSetConcurrency);
rs = st.executeQuery(SQL)
rs.getStatement().getConnection().close();
It actually closes connection. It never executes my code that returns the connection back to the pool. I am using JBuilder and when I am tracing the code, it never goes into my Connection implementation.
Any help will be greatly appreciated

You need to create a ResultSet Manager, just like you did with the Connection interface.
Your problem here is the getConnection() method of the ResultSet interface returns an object that implements the original Connection interface, not one that applies to your purpose. Then, of course, you'll be able to use the original close() method.
When you create the ResulSet manager, overwrite the close() pattern, according to your programming pattern.

Connection interface

Without implementing Connection interface in our class how we are using the some methods of that interface.
eg.
public class JDBCConnection
public JDBCConnection()
try
Class.forName("com.mysql.jdbc.Driver").newInstance();
con= DriverManager.getConnection("jdbc:mysql://192.168.1.80/bizicommerce","bipin","admin");
st=con.createStatement();
System.out.println("Connection Established");
catch(Exception e)
System.out.println("Exception in connection"+e.getMessage());
Bipin.V
}

Without implementing Connection interface in our
class how we are using the some methods of that interface.Someone else did implement it (in this case: the MySQL staff).
Edit: print the result of con.getClass().getName() to see what class provides the implementation.

Ni-fbus communications cannot connect interface

I am using NI-FBUS Communications Manager 3.2 with a NI PCMCIA-FBUS Series 2 card in a Ricoh R/RL/... series PCMCIA adapter on a desktop computer. I enabled the PCMCIA card via the Interface Configuration Utility. When I start the Comm Manager, I get the following error message:
NI_FBUS Communications Manager cannot connect interface 0 on the fieldbus board 1. Click OK to.....
Windows sees the Ricoh adapter card and the Series 2 card as working properly. If I install the Series 2 card in a laptop, the Comm Manager starts properly. The same series 2 card and Ricoh adapter card has been used in another desktop computer also running XP SP2.
How do I get this combination up and running?

I tried the PCMCIA card and adapter card in another computer running XP and NI-FBUS Communications Manager 3.1.1. The combination worked properly; the card was seen and the Comm Manager opened. When Configurator was opened, the device attached to the link was seen.
Is there a compatibility difference between Comm Mgr 3.1.1 and 3.2?

Traceroute issue- MPLS VPN on directly connected interfaces

I have 2 Catalyst 6509 Switches that Im trying to bring up and MPLS VPN connection between. The loopbacks can ping each other, as well as the directly connected interfaces (the interfaces travel through 2 switches, but no routing etc in between). An OSPF neighbor relationship DOES come up, and the routing tables appear normal. However, the MPLS VPN does NOT come up.
After further review, I found that the routing tables are correct on either side for the loopbacks (public addresses X’d out on first 3 octets):
SWITCH A:
Bryan-26th-CAT-2#sh ip route 10.255.2.2
Routing entry for 10.255.2.2/32
Known via "ospf 23532", distance 110, metric 2, type intra area
Last update from X.X.X.70 on Vlan65, 00:10:25 ago
Routing Descriptor Blocks:
* X.X.X.70, from 10.255.2.2, 00:10:25 ago, via Vlan65
Route metric is 2, traffic share count is 1
SWITCH B:
DAL-COLO-6509-1#sh ip route 10.255.2.3
Routing entry for 10.255.2.3/32
Known via "ospf 23532", distance 110, metric 2, type intra area
Last update from X.X.X.69 on Vlan65, 02:26:50 ago
Routing Descriptor Blocks:
* X.X.X.69, from 10.255.2.3, 02:26:50 ago, via Vlan65
Route metric is 2, traffic share count is 1
This is exactly the same for the directly connected interfaces on VLAN65. (X.X.X.69 and X.X.X.70). The ARP cache also shows to be correct:
SWITCH A:
Bryan-26th-CAT-2#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet X.X.X.70 147 0009.b6a4.b800 ARPA Vlan65
Internet X.X.X.69 - 001c.b144.5800 ARPA Vlan65
SWITCH B:
DAL-COLO-6509-1#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet X.X.X.70 - 0009.b6a4.b800 ARPA Vlan65
Internet X.X.X.69 141 001c.b144.5800 ARPA Vlan65
And once again, the OSPF Neighbor relationship does come up:
SWITCH A:
Bryan-26th-CAT-2# sh ip ospf neigh
Neighbor ID Pri State Dead Time Address Interface
10.255.2.2 1 FULL/BDR 00:00:30 X.X.X.70 Vlan65
SWITCH B:
DAL-COLO-6509-1#sh ip ospf neig
Neighbor ID Pri State Dead Time Address Interface
10.255.2.3 1 FULL/DR 00:00:33 X.X.X.69 Vlan65
In the Troubleshooting MPLS VPN manuals- it shows to test trace routes. All of our other connections like this the trace routes work fine. In this case though, I cannot trace route not only between the loopback interfaces, but between the DIRECTLY CONNECTED interfaces. I don’t know what this is. It should simply be a one hop trace route. I believe this is what is keeping the MPLS VPN from coming up. Any ideas? Here are the relevant OSPF configs and interface configs as well:
SWITCH A:
interface Vlan65
description Connection to DAL-COLO-6509-2
mtu 1580
ip address X.X.X.69 255.255.255.252

network X.X.X.70 0.0.0.0 area 0
Any ideas would be appreciated.
Thanks

Greg,
Can you explain more about your issue?. When you say MPLS VPN is not coming up, do you mean the ping (or traffic) from CE connected to one 6509 is not traversing the MPLS cloud to otehr CE connected to remote 6509?.
Do you have VRF enabled with respective RT import/export?. Do you have MP-BGP with VPNv4 AF enabled?.
To confirm if basic MPLS is working fine, Can you check if you have LDP neighborship up and running?. Use "show mpls ldp neighbor" to see the session.
Also do a "ping mpls ipv4 <remote-loopback> <mask>" and see if it works?.

Purchased iPhone 5 and can no longer connect interface to my seat Ibiza.

Bought an iPhone 5 with this lightning adapter thing expecting to be able to simply connect this adapter to my previous interface for my Seat Ibiza which worked, and still does work with my iPhone 4. Now with the iPhone 5 it only charges the phone and does not play the music, it works through an audio jack (3.5mm) but this is annoying as with the interface it allows you to be able to select playlists, songs etc. through the buttons on the car stereo and steering wheel. Through the audio jack it does not. Can anyone help with this? I have 10 days for an answer to this, otherwise i'm sending the bloody thing back!

EA2 - Cannot connect LDAP-authenticated users in 10.1 and 10.2, OK in 9.2

First, the relevant versions and such:
SQL Developer 1.5.0.52.03 (aka EA2)
Oracle client 10.2.0.1
Oracle database 9.2.0.6, 9.2.0.7, 10.1.0.5, 10.2.0.2, 10.2.0.3.
Hosts: Linux x86, Solaris
Most of the users in my databases are set up as global users (i.e. authenticated via LDAP). I've found that in 9.2.0.6 and 9.2.0.7, I can make connections of the basic type for global users as well as database-authenticated users.
In any 10g database I've tried (see the versions above), database-authenticated users work fine, but for connections with the global users in the same databases I receive ora-01017. I've tried both basic connections and advanced connections, supplying a thin JDBC string, with the same result. I have verified that the password is correct. The pattern persists across server OSs (Linux and Solaris).
I cannot make TNS connections at all, but that seems to require an 11g client and has been documented in an enhancement request separately.
If anyone has advice on this I would be happy to hear it. Thanks.

I should probably add that I am able to make successful connections via sqlplus and other tools (SQL Navigator) with the users that fail to connect in SQL Developer.

EA2/EA1 - SQL Developer freeze in file editor

I had a PL/SQL local file open (.pkb) with a database connection selected and compiled the file. There was a compilation error and when I went to correct it, SQL Developer froze (before my typing had updated the file).
I had the console open and it shows the following exception, which I assume is relate to the freeze:

I have just gotten basically the same exception on the console with EA2 using JDK 1.6.0_04. This time I had an SQL file open and had just looked at the history and switched back to the SQL tab to run a query.
Is the history tab trying to do something that is not yet being shipped with EA2?

EA2/EA1 - Icons when running with console

Feels incredibly picky, but when running SQL Developer with the console <SQLDevHome>/sqldeveloper/bin/sqldeveloper.exe (instead of <SQLDevHome>/sqldeveloper.exe), the Alt-Tab icon for the console has much better resolution than the icon for SQL Developer itself. When starting SQL Developer without the console, you only get the lower resolution icon.

Sue,
While there was a change in the Alt-tab icon between EA1 and EA2 - the icon still doesn't match the better resolution icon displayed for the console window. The application icon in EA2 looks like a fuzzier version of the EA1 application icon, rather than the better resolution icon used for the console window.

Netcfg - no connection, interface without devices connected

I have two interfaces eth0, eth1
eth0 (DHCP) - connect to router, provide internet
eth1 (STATIC IP) - connect with print server in my printer
- I expect interface should up without need to have powered on device connected to it
Everything worked fine, when interfaces were configured with /etc/rc.conf.
Now I configured network with netcfg and:
eth0 - up and everything ok
eth1 - no starts up, when no device is connected (powered off device connected) to this ethernet card
log:
# NETCFG_DEBUG="yes" netcfg eth1-static
DEBUG: Loading profile eth1-static
DEBUG: Configuring interface eth1
:: eth1-static up [BUSY] DEBUG: status reported to profile_up as:
DEBUG: Loading profile eth1-static
DEBUG: Configuring interface eth1
DEBUG: ethernet_iproute_up ifup
> No connection
DEBUG: profile_up connect failed
but when printer is powered on, interface starts up:
# netcfg eth1-static
:: eth1-static up [DONE]
network profile content
# cat /etc/network.d/eth1-static
CONNECTION='ethernet'
DESCRIPTION='A basic static ethernet connection using iproute'
INTERFACE='eth1'
IP='static'
ADDR='192.168.0.1'
Am I missing some setting? Maybe I should disable/enable something in profile?
Things to reproduce:
1. two ethernet cards
2. first connected network and second connected to switched off device, or not connected
3. configure 2 netcfg profiles (first - dhcp, second -static ip)
4. the second interface will fail to start up

Now I configured second interface - eth1 the old way in /etc/rc.conf:
eth1="eth1 192.168.0.1 netmask 255.255.255.0 broadcast 192.168.0.255 mtu 1492"
INTERFACES=(eth1)
While eth0 is configured by netcfg profile.
Both interfaces works. But my problem is not solved, because both interface should be configured in netcfg.
I think netcfg check if network is available and doesn't start eth1 interface, while device configured the old way in /etc/rc.conf doesn't perform this check. There should be option to disable it in netcfg profile.

Connecting Interface and recoding with Logic Express 9

Hi apologies if I've posted this in the wrong location. I need some help.
I have just bought an iMac (with Logic express 9) along with a focusrite saffire pro 14 sound interface.
i'm having difficulties getting a line in and out of the focusrite and into logic.
I currently have passive monitors plugged into an amp, which is then plugged into the headphone jack on the iMac, the focusrite is connected via firewire.
my mic is connected via xlr with phantom power into the focusrite, and my guitar (via an effect unit with built in pre-amp) is connected into the 1/4'' input. both signals are showing levels on the focusrite mixer software - but no sound. the only output from the sound interface is the firewire.
I can record, and play back in logic using my usb midi controller- USB direct into the iMac.
i've selected the focusrite as the driver in logic, also as the input device in system preferences on the iMac.
any ideas when I am doing wrong?
any help would be good
thanks
Chris

Hi,
there are some points where the big bear trap might have snapped onto your feet
First: You said you have selected the focusrite as the core audio input device in Logic. This is okay. But have you selected the correct inputs for the audio tracks you are recording to? You focusrite has 4 possible line inputs (1 and 2 are combined on the front in the middle of the XLR jacks, which are also inputs 1 and 2 for mics, and 3 and 4 are on the back).
When you connect a headphone to your focusrite, can you hear your mic or your guitar? (turn up the monitor volume as well as the headphones volume!)
Given you really have a good signal that goes into your focusrite, the same signal should be available in Logic *for the appropriate inputs* . It won't work if you have plugged your guitar into input 3 and have input 1 or 2 selected in the channelstrip's input selector tab.
Second: Given there's a signal coming into Logic, where does it go from there? The focusrite has 4 outputs, and you should connect your amp&speakers to them. If your amp&speakers are still connected to your iMac's headphone jack, you must select your Mac's "built in output" as the output device in Logic. The OS X preference pane has nothing to do with Logic's preferences. Don't confuse them.
Cheers,
Fox

Listener EA2: database connection pool and connection revalidation

Hi all,
As one can expect from early adopter release there could be some bugs but I can't find any references in forum to my situation:
* My 11g XE database and listener are starting as windows services when server boots operating system (Windows Server 2003 R2).
* I configured my web server (unsupported Jetty 9.0.0.M1) to start as windows service when operating system starts.
* Apex Listener 2.0.0.268.17.05 configured to connect with XE using JDBC thin driver with default settings (initial pool size 3, max statements 10, min connections 1, max connections 10, inactivity timeout 1800, abandoned connection timeout 900)
* Because web server starts a bit faster than Oracle database when apex connects first time it gets "ORA-12528, TNS:listener: all appropriate instances are blocking new connections" (could be that database still starting but already registered service with listener)
* From listener.log file I can see that all further connections made from Apex listener succeeds
* When I try to open any apex page with browser I am getting 404 error and apex listener logs error (*time is 2 days after system startup*):

* For some reason apex listener keeps first connection status and won't try to establish new connection if first attempt finished with ORA-12528
* The same scenario is valid when at time of web server start oracle database/listener is not available - even if database and listener starts and apex successfully establishes further connections all apex pages gets 404 error
* If I restart web server windows service (while oracle db and listener still running) browser opens apex pages without errors and apex listener does not log any errors
* I know that I can avoid this error delaying start of web server windows service but it would be nice to have production release 2.x without such bugs

Hi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.
Pete
