After creating a db using Database Configuration Assistant, I go to Enterprise Manager, log into it, and it tells me, that java.lang.Exception: Exception in sending Request :: null. OracleDBConsole for this db, and iSQLPlus services are started. When I run %ORACLE_HOME%\bin\emctl status dbconsole, it says
EM Daemon is not running.
How do I deal with this? How do I start the EM daemon?
Try this command:
%ORACLE_HOME%\bin\emctl start dbconsole

I have a problem with tibco Administrator TEA. My Tibco project is using a database connection with mysql server , and I have deployed it on TEA , when the Database Server is Down I see in Tibco logs DB Connection failed and when the database server is again up I am still seeing in Tibco logs DB Connection is failed , to solve that i need to restart the AppNode but I don't want to restart it every time . Is there any way to avoid that and let my application work automatically when the DB Server is up again . Thanks in advance
doesn't restart of application work? Do as follows:
* create moduleActivator process and include DBConnection call there and load all configuration within it to be used within process
* in the same bwp, catch exception event and do shutdown procedure, which will shut down your application.
Once DB connection is up, just start up your engine again and it should work without any exceptions.
Check and let me know if it works. If it doesn't, please share logs.
Iam able to open the admin web page just after installing informatica 9.6.1 on windows 10, but when i restart my machine (or when laptop went to sleep mode) again when checked the admin page says
"This site can’t be reached <hostname> refused to connect."
URL is <my machine hostname>:6008/administrator/
Is there something going wrong with the 6008 port after installation?
I used this URL for installation
https://www.edureka.co/blog/informatica-installation/)
I searched a lot on the internet but could not fix this issue.
Tried start/stop Informatica services, dint work.
please help
I had same problem while working on windows system with Informatica 9.6.1.
I believe any of the 3 processes: pmrepagent, pmserver and tomcat/JAVA services
is/are not running. In simple words Informatica is not up and running.
This helped me out.
open Command prompt in Admin mode
cd C:\Informatica\9.6.1\tomcat\bin
infaservice.bat startup
for more details refer this KB article

If you have also faced such problem while connecting to Informatica post installation then i recommend to check if you are well connected to the database which you opted while installing informatica (For eg. Oracle,sql server etc) with the same user and password which was seperately created to link the database with informatica.
If still you cannot open the Administrator homepage then you can cross check if the Informatica services are already started.You can restart the service if it is stopped and then the homepage will get open.
Seems like the service is not started. Please check the services and make sure Informatica is set to start automatically and that it's able to connect to DBMS where repository DB has been created.
When i installed Informatica that time i was able to login to admin console. But after restart i got - "site refused to connect " error. My informatica service & oracle db serv are running. But still i could not able to login to admin console. What is did was - i login to the schema what i used while installing informatica server through dbeaver tool. On my astonishment, after that im now able to connect admin console.
I found another error that caused this kind of issue.
Check in your system where information is installed and search for "Catalina.out"
See the error:
org.apache.catalina.loader.WebappClassLoaderBase clearReferencesThreads SEVERE: [localhost-startStop-2] The web application [/csm] appears to have started a thread named [phoneHomeScheduler] but has failed to stop it.
This is very likely to create a memory leak.
You need to restart the system and re-process the services.
I have an error when i try to start the Oracle BI server on Oracle VM VirtualBox. I am currently using SampleAppv607p-appliance.
This is my error.

I'm guessing here, your database is probably not up. So confirm the Oracle DB in VM is up and start BI services.
Based on your logs it looks like you're starting the WebLogic Admin Server via the Node Manager. However, during startup of the Admin Server it prompts for the username/password of domain user (e.g. weblogic) but Node Manager is not passing anything.
To solve this, go to $DOMAIN_HOME/servers/AdminServer/security and create boot.properties file. Edit the file and enter the username and password on separate lines. The username/password was defined upon domain creation, so make sure you know what these values are. See example below:
username=weblogic
password=welcome123
Start the Admin Server again. This will automatically encrypt the contents of your boot.properties file.
It always helps if you check the logs, as they provide more information on the error. In this case, you can check the following logs at the $DOMAIN_HOME/servers/AdminServer/logs/ directory.
In WebSphere 6.1 I have created a datasource to an Oracle 11g instance using the thin JDBC client.
In Oracle I have two users, one existing and another newly created.
My websphere datasource is OK if I use the component-managed authentication alias of the existing user, but fails with "invalid user/password" message if I use the alias of the new user. The error message is:
The test connection operation failed for data source MyDB (Non-XA) on
server nodeagent at node MY_node with the following exception:
java.sql.SQLException: ORA-01017: invalid username/password;
logon denied DSRA0010E: SQL State = 72000, Error Code = 1,017.
View JVM logs for further details.
There is nothing in the JVM logs. I have grepped all websphere logs and they do not mention my connection at all.
I can confirm that the username and password are correct by logging in via SQLPlus or (to prove the JDBC connection is OK) via SQuirreL.
I have checked in Oracle that the new user has all the system privs that the existing user has.
Any thoughts on what is going on or how I can debug this further?
Just FYI. I am guessing you are running WebSphere in Network Deployment mode.
This behavior you're experiencing is actually by design.
The reason for it is that the "Test Connection" button you see on the admin console, invokes the JDBC connection test from within the process of the Node Agent. There is no way for the J2C Alias information to propagate to the Node Agent without restarting it; some configuration objects take effect in WebSphere as soon as you save the configuration to the master repository, and some only take effect on a restart. J2C aliases take effect on restarts.
In a Network Deployment topology, you may have any number of server instances controlled by the same Node Agent. You may restart your server instances as you'd like, but unless you restart the Node Agent itself, the "test connection" button will never work.
It's a known WebSphere limitation... Which also exists on version 7.0, so don't be surprised when you test it during your next migration. :-)
If this happens to anyone else, I restarted WebSphere and all my problems went away. It's a true hallmark of quality software.
Oftentimes when people tell me they can't log into Oracle 11g with the correct password, I know they've been caught out by passwords becoming case-sensitive between 10g and 11g.
Try this :
data source definition
security
use the j2c alias both autentication managed by component and autentication managed by container
IBM WAS 8.5.5 Knowledge Center - Managing Java 2 Connector Architecture authentication data entries for JAAS
If you create or update a data source that points to a newly created J2C authentication data alias, the test connection fails to connect until you restart the deployment manager.
After you restart the deployment manager, the J2C authentication data is reflected in the runtime configuration. Any changes to the J2C authentication data fields require a deployment manager restart for the changes to take effect.
The node agent must also be restarted.
I have point my data source to componenet-manage authentication as well as container-managed authentication.Its working fine now........
Problem
Enterprise Manager starts and then hangs.
Environment
RAC installation on Windows, comprised of two nodes, node1 and node2. Enterprise Manager is installed on node1. We are able to get dbconsole to run briefly and and then it fails.
emagent.trc from node1 shows what appear to be two sets of relevant errors.
The first set of errors regard an inability to connect to the EM repository (which is on the same node).
The second error is associated with the "Instance Health Check initialization failed".
emagent.trc (node1)
Thread-5548 ERROR fetchlets.healthCheck: GIM-00105: Shared memory region is corrupted.
Thread-5548 ERROR engine: [oracle_database,clustername_node1name,health_check] : nmeegd_GetMetricData failed : Instance Health Check initialization failed due to one of the following causes: the owner of the EM agent process is not same as the owner of the Oracle instance processes; the owner of the EM agent process is not part of the dba group; or the database version is not 10g (10.1.0.2) and above.
Thread-5668 WARN http: snmehl_connect: connect failed to (node1:1158): No connection could be made because the target machine actively refused it.
Thread-5668 ERROR pingManager: nmepm_pingReposURL: Cannot connect to https://node1:1158/em/upload/: retStatus=-1

Thread-5708 ERROR upload: Failed to upload file B0000109.xml, ret = -2
I would like to get advice about how to proceed to troubleshoot these two errors in hopes of getting EM to start and stay up.
Regarding the first error, how would one troubleshoot an inability to connect to a web page running on the same node? This would appear to rule out firewall issues, etc. as a cause.
Regarding the second error, dbconsole and agent were started manually from the command line using a domain account, whereas the Oracle service runs under Local System (dbconsole was configured to use Local System on startup but failed, and can only be restarted via emctl start dbconsole.)
This part of the errors is the most promising.
the owner of the EM agent process is not same as the owner of the Oracle instance processes; the owner of the EM agent process is not part of the dba group;
You should check if all accounts running oracle are part of the ora_dba group.
