Unknown state or association field

Hi,
I have a table "client" that has many "request", both have an id attribute that´s the primary key. I need to query the request of a type that belong to a certain type of client. In the Request entity I have the following named query:
@NamedQuery(name="Request.findByTypeAndClient", query="Select r from Request where r.type = :type and r.client.clientType= :clientType")
The app server starts fine, but when I try just get to the index page I get the following error:
javax.faces.el.EvaluationException: javax.faces.FacesException: javax.faces.FacesException: Can't instantiate class: 'com.app.web.backing.Index'.. class com.app.web.backing.Index : javax.ejb.EJBException:
Exception Description: Unknown state or association field [clientType] of class [com.app.entity.Request].; nested exception is: Exception [TOPLINK-8030] (Oracle TopLink Essentials - 2006.8 (Build 060829)): oracle.toplink.essentials.exceptions.EJBQLException

Exception Description: *Unknown state or association field [clientType] of class [com.app.entity.Request].*
I've made sure I don't even use that query at the index page.
Why does it happen and how could I fix it?
I'm using jdev 10.1.3
Thanks in advance

That could be a hint...
The Client entity has a list of Requests, and the Request entity keeps a reference to the Client it belongs to. Since what I'm trying to list are the requests, and not the clients, I was expecting I could use the Client reference in the Request entity to make the query. Isn't it possible?

Unknown state or association field with @Transformation

I have a class that uses a Transformation mapping for the IP address field. The IP address is the string dot notation in the class, but is a long integer in the database. My entity class looks like this:
@Entity
@Table(name="LOCATION_MAP")
public class LocationMap implements Serializable {
bq. @Transformation \\ @ReadTransformer(IPAttributeTransformer.class) \\ @WriteTransformer(IPAttributeTransformer.class) \\ @Column(name="IP_ADDR") \\ protected String ipAddr; \\ ...
IPAttributeTransformer is a class that implements both org.eclipse.persistence.mappings.transformers.AttributeTransfomer and org.eclipse.persistence.mappings.transformers.FieldTransformer.
When I attempt to execute the query, "select location.ipAddr from LocationMap location", it gives me the error Error compiling the query [(select location.ipAddr from LocationMap location|http://select location.ipAddr from LocationMap location]), line 1, column 16: unknown state or association field (ipAddr) of class (com.example.LocationMap).
If I comment out the @Transformation, @ReadTransformer, and @WriteTransformer annotations, then I don't get the error, but of course I also don't get the transformed IP address.
This mapping worked with TopLink 10g and the XML descriptor file, but I am trying to migrate to 11g and JPA with annotations.

Hello Ryan,
The example I have does the following:
@ReadTransformer(method="buildNormalHours")
@WriteTransformers({
@WriteTransformer(method="getStartTime", column=@Column(name="START_TIME")),
@WriteTransformer(method="getEndTime", column=@Column(name="END_TIME"))
@Property(name="attributeName", value="normalHours")
protected Time[] getNormalHours() {
return normalHours;
where buildNormalHours looks like:
/** IMPORTANT: This method builds the value but does not set it.
* The mapping will set it using method or direct access as defined in the descriptor.
public Time[] buildNormalHours(Record row, Session session) {
Time[] hours = new Time[2];
/** This conversion allows for the database type not to match, i.e. may be a Timestamp or String. */
hours[0] = (Time) session.getDatasourcePlatform().convertObject(row.get("START_TIME"), java.sql.Time.class);
hours[1] = (Time) session.getDatasourcePlatform().convertObject(row.get("END_TIME"), java.sql.Time.class);
return hours;
Another uses a transformer class for the read:
@ReadTransformer(transformerClass=org.eclipse.persistence.testing.models.jpa.advanced.AdvancedReadTransformer.class)
which extends the org.eclipse.persistence.mappings.transformers.AttributeTransformer class and implements a buildAttributeValue method.
Hope this helps,
Chris

Query on field of embedded object - "Unknown state or association"

I'm trying to define a query which selects entities on the basis of a field nested in an embedded field of the entity class.
The query looks like:
select inv from Invoice inv where inv.weekNo.year = :year AND inv.weekNo.weekNo = :week AND
inv.member.id = :memberCode
where:
@Embedded
public BusinessDate getWeekNo() {And the BusinessDate class has a year and weekNo field defined for persistence.
The result is :
Exception Description: Unknown state or association field [year] of class [com.cc.ei.model.data.BusinessDate].
Hibernate compiles this query OK but toplink rejects it.
What I'd like to do is put this under the Member entity as a filtered query (I need Invoices for a specific week for a given member) but there's no @Filter in the javax.persistence stuff, that I can find.

Toplink essentials.
The year attribute is simply an integer field, mapped to a "YEAR_NUMBER" column.
The @Filter I'm talking about is an extra facility in Hibernate annotations (outside of the javax.persistence stuff). The idea is that when you've got a one-to-many relationship you don't always want every child record, in this case, for example, I want the invoices under a Member limited to a specific business week (matching week number and year).
It's not very elegant to have to, effectively, ignore the existing relationship and use a stand-alone Query.
As to the original problem I've concluded the best way is probably to put the year and week number fields in the Invoice entity separately, and build my BusinessDate object from them. Using BuisnessDate as an embeddable would have been more elegant, but it's not the end of the world.

Error: unknown state or association

hi:
I want to call a jpql sate ""select model from Webusercontact model where model.weblogon = :firstParam", I don't think there is the syntax error for the statement, but it allways displays: " Error compiling the query [select model from Webusercontact model where model.weblogon = :firstParam], line 1, column 52: unknown state or association field [weblogon] of class".
I am new for JPA, could I get any help?
I use myeclipse, the class Webusercontact is built by system, it also creates the classes: WebusercontactId, WebusercontactDAO, IWebusercontact, AbstractWebusercontact and EntityManagerHelper.

"weblogon" must be the variable or property name for the class (not the database column name). Perhaps include your class.

Services in unknown state

Hello All,
I have a 2 node RAC cluster running on Oracle 11G on Windows 2003. Everything appears to be working fine, but I have some services in an unknown state.
If I stop all services using CRSCTL STOP CRS on any node, all services go offline as expected and OEM shows the fact that one of the nodes (instances) is no longer available.
If I then issue CRSCTL START CRS on any node all services start up OK except for the .INST and .DB services. Issuing the CRS_STAT -T the .INST service shows as 'online' but its state is 'unknown'. The .DB service for the database shows as 'offline'.
The stopped DB Instance does not start up automatically. If I try to start it using SRVCTL I get a CRS-0223 'Placement' error message . To get my stopped DB Instance to startup the only way I have found is to log on to sqlplus as SYS and issue the startup command. The instance then starts up with no problems
I'm confused as to why the above mentioned .INST and .DB services dont appear to be in a correct state yet my RAC cluster appears to function correctly. Any advice on this would be greatly appreciated .
Thanks,
Shaun

I wouldn't use crsctl stop crs to stop the services, that shutdown the entire clusterware environment. Use "crs_stop -all" instead.
As for your issue, did you check the alert log just after clusterware tries to start up the db?
Check the alert log on the databases that are not coming up automatically. There's probably an error in there.

Statements in calculation fields

Can you use sql statements in calculated fields, for instance can you use a statement like IF(GL_SEGMENT-04='401000'TO'409999'THEN SUM(GL_BALANCE_PERIOD_BAL_DB-GL_BALANCE_PERIOD_BAL_CR)
I would think that you could use statements within calculated fields but I am having no luck.
Thanks in advance

You are so close, I guess. An alternative syntax you may try:
SUM(CASE WHEN SEGMENT3 BETWEEN '401010' AND '405999' THEN PERIOD_NET_DR-PERIOD_NET_CR ELSE 0 END)
You may get error message for not using table prefix. In that case, use the table prefix with each field. As you have seen, Discoverer takes care of the prefix when it first executes the formula. Regarding 0 balance, make sure that the sum is not zero for that range. You may also try with a bigger range. Good luck!

Error in collect statement(non-key fields must be numeric)...

Error in collect statement(non-key fields must be numeric)...
Hello Experts,
I created an internal table based from a ztable. The structure of the ztable is

4. ANLKL -> PRIMARY KEY
5. KTANSW -> PRIMARY KEY
6. KOSTL -> PRIMARY KEY

An error is showing saying 'You can only use the collect command in a table if all of its non-key

Composites in "Unknown" state after managed soa server restart

Hi,
I am using SOA suite 11.1.1.6 version on 64 bit OEL Linux. I am getting following error in managed server output log files:
Feb 20, 2013 5:59:32 AM IST> <Error> <oracle.integration.platform> <SOA-20003> <Unable to register service.
oracle.fabric.common.FabricException: Error in getting XML input stream: oramds:/deployed-composites/WirelessEnterprise/svcEnrichSEARequest_rev1.0/svcEnrichSEARequest.wsdl: oracle.mds.exception.MDSException: MDS-00054: The file to be loaded oramds:/deployed-composites/WirelessEnterprise/svcEnrichSEARequest_rev1.0/svcEnrichSEARequest.wsdl does not exist.
Though this composites gets loaded, the composites dependent on this composite goes into "Unknown" state. Other composites are properly loaded on server restart.
Please let us know if anybody has any solution to this problem.

Hi,
Thanks for your help.
we have narrowed down to problem now.
The actual problem occurs while redeploying same composite on same revision.
E.g 3 composites A, B and C are deployed on and in "Up" state.
B And C composites depends on A.
B composite composite.xml has following entry
<import namespace="http://xmlns.oracle.com/A"
location="oramds:/deployed-composites/Enterprise/A_rev1.0/A.wsdl"
importType="wsdl"/>
same entry exist for C composite.xml as well.
Now whenever composite A is redeployed with same revision (1.0 in our case), and managed servers are restarted, B and C composites goes in to "Unknown" state.
Moving A.wsdl to /apps/wsdl/* in MDS works but it duplicates the A.wsdl file beacause it also exists in MDS @ /deployed-composites/Enterprise/A_rev1.0/A.wsdl
Please let us know if anyone has any solution.
Thanks,
Rupesh.

Resources in UNKNOWN state after failover

Hi,
I'm new to RAC and trying to understand how to bring a node back online. See crsctl output below.
I've noted that the listener, ons and the database on the db01 node are all in an UNKNOWN state. The vip state is INTERMEDIATE.
The cause was activating a virtual NIC on the db01 node. The vNIC was deactivated but not before a failover.
I see oc4j is offline also which I believe is contributing to OEM dbconsole being unnavailable.
Please advise/suggest the best way forward to remedy this.

Thanks Sebastian,
I was a little busy so only now do I have the time to reply.
Another DBA was able to troubleshoot the root cause of the issue, which I will put here for the benefit of all.
Essentially the hosts file (see snippet below) contained multiple entries for the node name, both on the "localhost" line and also in the "Public" section. A quick edit solved the problem.

Cluster services UNKNOWN state

Hi,
I am having two node cluster database. I have some doubt
If cluster services will go UNKNOWN state in first node existing connection will failover to second node?
New connections will try to connect first node?

Maybe...
New connections will try to connect first node?If nodex is down any connection attempt should go to the remaining nodes.

New weblogic instances goto unknown state

Hi ,
When i create a new weblogic server using Admin console , the server at time shows up in UNKNOWN State, where as normal behaviour is to show in SHUTDOWN state. have you seen or know about this kind of behaviour before? The problem with this unknown state , is once i create and change properties , i cannot able to start the server from Admin Console.
But when i restart the admin server, these new servers goto "shutdown" state, after which i could able to start the servers fine.
But i had to restart admin server everytime i create a new server , which ends up in unknown state.
im using WLS 10.3.6 version with node manager configured and jvm args are -Xmn 256m -Xmx512m respectively, let me know if you need more info on this
Thanks in advance,
Patra

Hi ,
sorry for the late response.
FlyingBird - here are my answers to your questions.
I created managed servers - Admin server is already created long back.
yes,, both startWeblogic.sh and startNodeManager.sh are started. I could able to see the node manager is reachable from admin console and node manager process has started fine on the node.
Sharmela - I dont see any error reported.
Since the new managed servers that are created , are not started up yet, ( i.e. i could not able to start them as they end up in UNKNOWN state ), they does not have the directory structure created in the linux box. so , there is no <MSX>/logs dir created so , im clues less on what is going on.
i have like more than 60 managed servers on this admin console. this issue was not there when there were less managed servers ( ~ 20 but happens everytime i create a new managed server. Not sure, what is the issue. Hard part is , i dont find any logs for it to find a direction in troubleshooting. Appreciate your advises.
Let me know if you need more info.

SOAINFRA UNKNOWN State

Hi,
Have a clustered environment in which SOAINFRA(managed server) goes into unknown state once in every 5-6 days.
Weblogic Server will still be in running status but both the SOA manage servers show the state as UNKNOWN
Checked the nohup.out file but could not get the log of any error message.
Any suggestions..?

Hi,
Have you checked managed server logs, in $DOMAIN_HOME/servers/soa_server1/logs ? Where soa_server1 with the name of the managed-server...
Cheers,
Vlad

Ethernet showing 'Unknown state'

I have just bought a time Capsule wanted to backup using ethernet, but my iMac wouldn't detect the capsule. I tested it with my laptop and it found it fine, so the cable and capsule aren't the problem.
I found both ethernet and firewire ports showing 'inactive'. I activated them but now they both show 'unknown state'. I have always used wireless so don't know if the ethernet was always like this.
Any help would be greatly appreciated.
Mike

I don't see where you said AirPort was OFF in the first post. And I did not mean to imply that you did not already have it connected with a Ethernet cable. Obviously, if you want it wired, there has to be a wire...
Try going to System Preferences Network pane. In the sidebar, if AirPort is listed above Ethernet, click on the little gear icon and select +Set Service Order+. Make Ethernet appear first on the list. Then try restarting.
