I have a Websphere 8.5.5.12 installation with multiple applications running on it. For a given Middleware Server, I'd like to be able to list all applications associated with it using Jython.
I have gone as far as writing this code:
wsadmin>print AdminApp.list("WebSphere:cell=myCell,node=myNode")
However this is retrieving applications for a different Dynamic Cluster
If I add a specific server, it errors out
wsadmin>print AdminApp.list("WebSphere:cell=myCell,server=myServer")
ADMA0184E: myServer is not a valid target.
Your query should look like:
wsadmin>AdminApp.list("WebSphere:cell=myCell,node=myNode,server=server1")
It appears you're missing the node identifier in your query. And if wsadmin still returns "myServer is not a valid target", then the server name is wrong, try looking at your app server profile directory structure to double check it.

I am new to Mule and I have been struggling with a simple issue for a while now. I am trying to connect to flat files (.MDB, .DBF) located on a remote desktop through my Mule application using the generic database connector of Mule. I have tried different things here:
I am using StelsDBF and StelsMDB drivers for the JDBC connectivity. I tried connecting directly using jdbc URL - jdbc:jstels:mdb:host/path
I have also tried to access through FTP by using FileZilla server on remote desktop and using jdbc URL in my app - jdbc:jstels:dbf:ftp://user:password#host:21/path
None of these seem to be working as I am always getting Connection exceptions. If anyone has tried this before, what is the best way to go about it? Connecting a remote flat file with Mule? Your response on this will be greatly appreciated!
If you want to load the contents of the file inside a Mule flow you should use the file or FTP connector, i don't know for sure about your JDBC option.
With the File connector you can access local files (files on the server where mule is running), you could try to mount the folders as a share.
Or run an FTP server like you already tried, that should work.
There is probably an error in your syntax / connection.
Please paste the complete XML of your Mule flow so we can see what you are trying to do.
Your usecase is still not really clear to me, are you really planning to use http to trigger the DB everytime? Anyway did you try putting the file on a local path and use that path in your database url. Here is someone that says he had it working, he created a separate bean.
http://forums.mulesoft.com/questions/6422/setting_property_dynamically_on_jdbcdatasource.html
I think a local path is maybe possible and it's better to test that first.
Also take note of how to refer to a file path, look at the examples for the file connector: https://docs.mulesoft.com/mule-user-guide/v/3.7/file-transport-reference#namespace-and-syntax
If you manage to get it working and you can use the path directly in the JDBC url, you should have a look at the poll scope.
https://docs.mulesoft.com/mule-user-guide/v/3.7/poll-reference
You can use your DB connector as an inbound endpoint when wrapped in a poll scope.
I experienced the same issue when connect to Microsoft Access Database (*.mdb, *.accdb) using Mule Database Connector. After further investigation, it's solved by installing Microsoft Access Database Engine
Another issue, I couldn't pass parameter to construct a query as same as I do for other databases. e.g.: SELECT * FROM emplcopy WHERE id = #[payload.id]
To solve this issue:
I changed the Query type from Parameterized into Dynamic.
I generated the query inside Set Payload transformer (generate the query in form of String, e.g.: SELECT * FROM emplcopy WHERE id = '1').
Finally, put it into the Dynamic query area: #[payload]
I need to install multiple iDempiere instances in one server. The customized packages are different in build and the db they are using. Is there any way to deploy both of it in one server and access like localhost:8080/client1, localhost:8080/client2 . Any help appreciated.
When I want to reference several application servers I need to copy the path of various installations
and change the database name and port of each application :
/opt/idempiere-server-production/ (on port 8080 for example) for production
And
/opt/idempiere-server-test/ (on port 8081 for example) for test
the way you said is not possible, because the idempiere server for webapp is known as
http://hostname:port/webui
Running multiple instances of idempiere on a single server is not too difficult.
Here is what you need to take care of:
Install the instances into different directories. The instances do not need to share any common files. So you are just fine making a full installation for each instance.
Make sure each instance uses its own data base. Use different names for the instance data bases.
Make sure the idempiere server instances use different tcp ports.
If you really should need to use a single port to access all of the instances you could use a http server like apache or ngnix to do define virtual hosts. Proxying or use of rewrite rules will then allow you to do the desired redirections. (I am using subdomains and apache mod_proxy to do the job)
There is another benefit to using subdomains for browser access: If all your server instances use the same host name the client browser will sometimes not be able to keep cookies from different instances apart, which can lead to a blocked session as discussed here in the idempiere google group.
Use different DB user names. The docs advise not to change the default user name Adempiere and this is ok for a single instance installation. Still if you use a single DB user for all of your instances you will run into trouble once you need to restore a database from a backup file. The RUN_DBRestore.sh will delete and recreate the DB user which is not possible when the user owns more than one DB.
You can run all of your instances as services in parallel. Before the installation of another instance rename the service script: sudo mv /etc/init.d/idempiere /etc/init.d/idempiere-theInstance. Of course you will need to do some book keeping work wth the service controller of your OS to ensure that the renamed services are started as desired.
The service controller talks to the iDempiere server via the OSGI console. For this to work without problems in a multi instance environment you need to assign a different telnet port number to each of the instances: in the editor of your choice open the file /etc/init.d/iDempiere. Find the line export TELNET_PORT=12612 and change the port number to something else.
Please Note:
OS specific descriptions in this guide are for Ubuntu 16/18 or Debian, if on another OS you need to do some research.
I have been using the described approach to host idempiere versions 5 and 6 for some time now and did not have any problems so far. Still make sure you do your own thorough tests if you want to go that route.
If you run into any problems (and maybe even manage to solve them) please report back to the community. (by giving your own answer to this question or by posting to the idempiere google group) Thanks!
You can have as many setups on your server as you like. When you run the setup to create your properties, simply chose other web ports for each installation. You also may need to slightly change the webservers configuration if they have some default ports.
The task is to have an Oracle report generated daily, automatically, and e-mailed to a user.
So I've sort of got this working (it works if I hardcode one of the reports server names below).
I created a job on the database that will generate the report. I'm able to get the report to email as a PDF to the destination with this command:
UTL_HTTP.REQUEST('http://server/reports/rwservlet?server=specific_report_server &report='||p_report_name||'&userid='||p_connstring||'&destype=mail'||p_parameters||'&desname='||p_to_recipientlist||' &cc='||p_cc_recipientlist||'&bcc='||p_bcc_recipientlist||'&subject=%22' || REPLACE(p_subject,' ','%20') || '%22¶mform=no&DESformat=pdf&ENVID='||p_envid);
That works great...
The problem however is that my organization has two report servers that are load balanced. Our server team could take down one of the servers without really any warning, so I can't just hardcode the report server name (the ?server= parameter above) with one of the report server names because it will work for a while, then when that server goes down, it will stop working.
My server team asked me to look for a way to pull the server from the formsweb.cfg file or from default.env value within the job (there are parameters in there that hold the server name). The idea there is that the "http://server" piece will direct the report to be run on the appropriate server, and the first part of the job could get the reports server name from the config file that the report is run on. I'm not sure if this is possible from the database level, or how to do this. Any ideas?
Is there a better way that this can be done, perhaps?
If there are two load-balanced servers, that strongly implies that the network folks must have configured some sort of virtual IP (VIP) for the service. You (and everyone else) should be using that VIP rather than a specific server name.
For example, if you have two servers reportA.yourdomain.com and reportB.yourdomain.com, you would almost certainly create a VIP for reports.yourdomain.com that load balances between the two servers (and knows whether one of the servers is down or whether a new reportC server has been added). This VIP would either do the load balancing itself or would point to an actual physical load balancer that distributes the traffic. All applications would reference the reports.yourdomain.com VIP rather than any hard-coded server names.
The context is that I have a script that automates the update or deployment of applications on WAS 6.1 servers from a DMGR. This script use a setting file that contains the application name, the server cell, node and name. I don't want to make manually a file for every application. I searched IBM for a way to get all these informations and can't find how.
http://pic.dhe.ibm.com/infocenter/wasinfo/v8r0/index.jsp?topic=%2Fcom.ibm.websphere.base.doc%2Finfo%2Faes%2Fae%2Ftxml_listapp.html
I know how to list apps on a server but I need to link all those infos together.
$AdminApp list (any options would give me info I need?)
Use the scriptLibrary included in WAS version 8:
AdminApplication.listApplications()
Returns: List of the available application names in the respective cell.
I realise there are some similar questions on here already but I couldn't see one that matched my problem so I'm afraid I had to ask a new question.
I have a webservice running on a server, which is throwing a ORA-12154: TNS:could not resolve the connect identifier specified" error. However when I log onto the said server i am able to tnsping the entry successfully, and connect to it via sqlplus, but not through the webservice.
If anyone has any suggestions as to things to look for then I would greatly appreciate it.
Cheers
Some other things to look at include:
If you're using a service name instead of SID, are you specifying the entire service name?
If you're using the ORACLE_SID environmental variable, check the case (mydb vs MYDB)
Check for a sqlnet.log file
If you're using a username/password#SID connect string, you may need to quote your password if it contains special characters (like an # symbol).
The webservice can't find tnsnames.ora which usually means that you didn't set up Oracle's environment properly when starting the process. This usually means you didn't source oraenv.sh in the shell script which starts it.
So your interactive login works - what is different between your interactive login and the user that runs your web service?
Are they the same user? If not then you will need to update some of your configs in order to make the Oracle client files available to the webservice.
Details like Operating System, Oracle Version, etc are always a help.
