Unified CCX Engine JVM Heap counter monitoring

Greetings!
I'm looking for solution how I can monitor Unified CCX Engine JVM Heap counter from external system.
Description for the object in RTMT:
Object: Unified CCX Engine JVM Heap
Counter: PercentageMemoryUsedAfterGC
Desc: This represents the percentage of heap memory that is used by the application after the last full Garbage Collection cycle.
At the moment I see the only one solution which is to get the value via SNMP. But I couldn't find the OID for this counter. Can anyone tell me where I can find it or suggest another solution ?
Thanks in advance for your answers.

AMOR is a new one for me, and I like it!
I have not tried to access this API from UCCX, however, it's just another VOS API which should be the same on all VOS platforms. An attempt to query the UCCX server for its PerfMon WSDL, does not return one, so perhaps it doesn't. It did work on my CUCM.

Cisco Unified CCX Engine RE_ENTRANT_ERROR

Hi! I have the following case:
Abonent A calls to route point B that is registered in UCCX as a trigger.
The route point plays greeting and redirects abonent A to cti port C that is controlled by UCCX.
Cti port C calls to operator D. Directory number D has assigned external call control profile.
The external call control profile sends a http request to the routing rules servlet.
The routing rules servlet answers with divert on directory number E. Directory number E is not associated with UCCX resources.
Abonent E answers the call. UCCX drops the call immediately.
In UCCX logs i discovered an error:
Date: Mar 16 17:20:06
Machine Name: ccx105
Severity: Error
App ID: Cisco Unified CCX Engine
Message: : 58: ccx105: Mar 16 2015 10:20:06 AM.788 UTC : %UC_CONTACT_MGR-3-RE_ENTRANT_ERROR: %[exception=java.lang.IllegalStateException: Unsupported re-entrant method call][contact.impl.id=24185/1][UNKNOWN_PARAMTYPE:Contact id=7][contact.type=Cisco Agent Call][contact=CallContact[id=7,type=Cisco Agent Call,implId=24185/1,active=true,state=CALL_ANSWERED,inbound=true,handled=false,locale=en_US,abo][contact.class=com.cisco.call.CallContact][ClusterID=][NodeID=ccx105]: Re-entrancy error
I am failed to find any description for this error. What does it means? Is this case supported by UCCX?

In our case, when we do the backup, it is only 94% completed with the following error:
"ERROR: Unified CCX Cluster View Deamon is not running. The Unified CCX database backup cannot be initiated., Backup Completed..."
The CCXCOMPONENT got the error while the rest of the components succeeded. Any solution?

CCX Engine status shutdown

Hi
in UCCX 8.5 Cisco Unified CCX Engine is in shutdown status from CCX Serviceability. I added CM Telephony Call Control Group with 10 CTI ports. I can see CTI port in CUCM that are created, but their registration status keep state "unknown"
I am using UCCX 8.5.1.10000-37 and CUCM 8.6.2.20000-2.
Please for your suggestion what I am missing. I am attaching a MIVR log.
Thank you,
Petko

Hi Anand,
I run Data Synchronization
everything is in sync:
Call Control Group(s)
0 - Unified CM Telephony Group #0
CTI Ports
In Sync
CM Telephony User(s)
User ID
cc__1 - In Sync
Device Association
In Sync
I restart Cisco Unified CCX Engine, but after 2 minutes all subsystems of CCX Engine went to shutdown state.

Cisco Unified CCX Go To PARTIAL SERVICE

Cisco Unified CCX Engine go to PARTIAL SERVICE and after one or two days the IVR goes down no calls received.
i have a ccx 7

Hi Ahmed,
Please elaborate on the issue.
Can you go to control center and let us know which service under CCX Engine goes into partial , causing the engine to go into partial.
A screenshot will be helpful. Also if its CM telephony service, I should recommend a data resync.
Regards,
Chuck

CCX Engine Shutdown - UCCX 802 on VMWare

All,
Installing UCCX 802SU3 on VMWare. CUCM version is 8.5.1SU3. Checked compatibility matrix and these two are compatible.
I am using VMWare Server 2.0 as a Host. VM Server configured:
Red Hat Enterprise 4 (32 Bit)
2 x CPU
4 GM RAM
2 x 146 GB HD
SCSI Controller is LSI Logic
Install was successful. I used a temporary license that was working for a UCCX 802SU3 system on physical server (MCS 7845). Initial configuration was successful.
When in UCCX Serviceability page > Control Centre, following three services are SHUTDOWN:
Cisco Unified CCX Engine
Manager Manager
Subsystem Manager
I tried to start CCX Engine, they went to starting --> Partial Service --> Shutdown. All other services are IN SERVICE.
I have tried Demo License and the same problem happened.
Anyone knows about this problem? If any of you successfully installed UCCX 802 on VMWare, I would like find out how your VM Server be configured.
Thanks,
Wenqian

Wenqian,
CUCM nor UCCX are not compatible with VMWare Server, only VMWare ESXi 4.0+, so if this is a production environment you are running on unsupported platform.
I am not saying that it is your issue though for the service failure, your only to figure out what the issue is to look into UCCX logs, starting with MIVR logs. You can gather the logs by using RTMT application.
HTH,

Setting SNMP counter monitor trap polling interval and threshold

Hello,
I want to send a trap when the WLS heap reaches a high water mark.
My questions are:
1) with a threshold of 10MB, I receive the trap when heap is 256MB. 256MB is
teh max heap setting when starting jvm. Why do I receive the trap @ 256MB and
not at 11MB?
2) With a polling interval of 30 seconds and offset/modulus of 0, I expect to
receive a trap every 30 seconds for as long as the heap is over 10MB. I only
receive the trap once @ 256MB. Why don't I receive multiple traps?
I'm using the SNMP counter monitor where:
mbean type = JVMRuntime
mbean name = MainServer
monitored attribute = HeapSizeCurrent
polling interval = 30 seconds
threshold = 10000000
offset = 0
modulus = 0
I'm using WLS 7.0 SP1 with WebLogic Temporary Patch for CR090721 12/06/2002 15:08:40
Thanks,
BT

Jing,
Could you please post how your config.xml looks after you set this Trap?
Also, once you configured a monitor trap, you need to re-start the admin
server. For more information on how to setup a counter monitor refer to
the BEA docs at,
http://e-docs.bea.com/wls/docs61//snmpman/snmptraps.html#1071147

Can you alter the JVM heap space size for all Windows users?

Hi,
I have used the "-Xmx" option to increase the Java Heap space for my Java application. This works fine, but all other users on my system still have the default heap space setting and I want them to have use an increased heap space as well. I cannot alter the JVM heap space at the command line since our Java application is started via an ActiveX bridge from a Windows application.
So far I have found one potential, but not really good solution; I have figured out that I can copy the deployment.properties file containing the altered JVM heap setting from the "Application Data\Sun\Java\Deployment" folder in my own Windows "Documents and Settings" folder to the same folder of another user. However, this is not a really good solution since we are running a system with about 60 users and often new user accounts are created and sometimes people forget to copy the deployment.properties file.
Does anyone know a better solution. I've tried to search the Windows registry or the JRE files for a default JVM heap space setting but I can't find it anywhere. Still on some systems the default is 64Mb and on others 96Mb, so I guess there must be a setting somewhere?

The following is my eclipse.ini:
-vmargs
-Xms256m
-Xmx512m
-Dfuego.fstudio=true
-DprodMode=preProduction
-Dbea.home=C:\bea\albpm6.0\studio\..
-Djava.endorsed.dirs=""
-XX:PermSize=256M
-XX:MaxNewSize=256M
-XX:MaxPermSize=1024M
but i think this configuration just effect the eclipse, not embed bpm engine. I also change the engine preference, increase the heap size, but engine crash as before.
I want to change the jvm from jdk to jrockit, i hope any suggest.

Capturing the JVM heap usage information to a log

When using weblogic 6.1sp3 the console under monitoring/performance a graph is
displayed with the historical JVM heap usage information. Is there any way to
capture this information to a log?

For heap size before and after each gc, you could pass the -verbose:gc option to the JVM
on startup:

Cisco Unified CCX 8.5.1 problem in CSD when the CCX bascull

Hi,
I have a problem with the Cisco Supervisor Desktop. There is a cluster of 2 Cisco Unified CCX, system version: 8.5.1.10000-37. At this moment the IPCC2 is the Main and if the system bascull to the IPCC1 we have a problem with the Cisco Supervisor Desktop, the CSD does not monitors the agents.
Which could be the problem?
Thanks,

Correct 64kbps.
Audacity or any sound application can do this.

But I am getting this alert from SCOM and SCOM has no information about the alert for me to find out what to do - thought that was the point of SCOM to let you know of problems and how to resolve them. :)
The alert is coming from the Error Count Monitor that is part of the Hyper-V Management Pack Extensions (v 4.0.0.0)
I have tried looking in the Event Logs on the Host and there doesn't seem to be any storage related errors there. I am trying to establish if this is a false positive, why it is happening and if it is safe to override and ignore.
There is nothing on the Product Knowledge tab and nothing on the Alert Context other than what I have already mentioned (see below).
Thanks for responding.

Can I get the reference to all objects in JVM Heap?

Hello,
Thanx in advance for reading (and replying) to this problem.
I need to find an object whose reference I dont have.
I feel the best place to search for is the JVM heap.
If I get that JVM heap, and am able to get all the objects created, I can locate the particular object that I am looking for.
Is there a way to od this????
Any suggestions ????
Vikas

JVMTI will mostly help you in this case. But i recomend you to review you application design, because such services are unsafe and rather tricky.

So I think that if can off JVM heap Memory used in the Near-Cache front-tier?
Or can help how to config the off JVM heap Memory used in the Near-Cache front-tier.
Thanks.

Only local-scheme and class-scheme can be used in the front-scheme of a near cache.

2. NetWeaver 7.0 (2004s)
3. HP JDK 1.4.2 64bit
in machine one, also host one , the Message Server(SCS) | Central Instance and Oracle DB instance installed.
the DI (Dialog Instance) installed in second host alone. and it contain two server node .
what is the best configuration about JVM heap and GC parameters for each host(CI adn DI)
please help

The best configuration depends not only on your hardware, but also on the number of users and the way the system is being used.
For parameter recommendations of JVM, please check note 723909 - Java VM settings for J2EE 6.40/7.0
Kind regards,
