Why 12C Grid Control shows Target status down/Unavailable?

Hello,
The grid control 12.0.2 on Oracle Linux 5.9 shows that status of target /EMGC_GCDomain/GCDomain/EMGC_ADMINSERVER as down where as it is up and running and I can log into admin console.
Please note that repository, OMS, weblogic all components are on same server.
It is also showing that following are unreachable where as these are up on same server
EM Website System
Management Services and Repository
How can I diagnose and fix this? Where to start?
Thanks.

Have you checked the agent status with emctl status agent? Is the OMS available there and when was the last upload time?
You can also try emctl upload agent and see if this helps.
Is the dbsnmp account unlocked with correct password in the target database?

Oracle 12c Grid dashboards shows wrong status of target database

Hello Community,
A database in the 12c Cloud control, even if the database target is up, it says it is down. Agent, listeners are also added as target on that particular host. They show correct state where as database target show as down. Database is in 12c. [12.1.0.2.0] I have referred doc.id 1535613.1. That did not help here.
Every time it is showing down with an additional message "got a minus one from read call "
Agent Core version is 12.1.0.3.0
Could you please guide me in this problem?
Kindly let me know if I am giving sufficient information for preliminary investigation or I need to provide some more details.

Hi ,
Did you try to test the connection?

Grid control shows process down but process is up

How can I correct this issue?
the processes are running, but grid control shows them down, is there a manual refresh that needs to be done?

the agent is running on a windows server.
it has been showing down for about a week, and it is still showing down, but all the processes are running.
while looking in grid control the arrow on the top left is pointing down, and red
but when I look further down the screen, I see that all of the arrows are pointing up and green.

Monitoring oracle database from OEM 12c grid control

Hi,
I am using OEM 12c grid control to analysis various server's performance. The application database in oracle database v11g. Is there any problem if i add database on oem to monitor? To be more clear, If it creates any conflict between database's em and oem's em when i want to deploy em agent on database ? Is it necessary to remove database's EM before installing oem agent on it?

DB target status shows "Up" in Grid Control console, but actually "Down"

We've recently installed Grid Control 10.2.0.5. We recently noticed issue regarding false status indicators for several db targets monitored. From GC console, db target show status "Up" (Green Arror) when db is actually down. Should show status as being down (Red Arrow). Is this a known bug? Has anybody experienced this behavior? Can anybody please advise and/or provide solution to this issue?
Thank you in advance.
Best,
Doin

It seems that properties are missing..
Follow the steps,

Grid Control showing excessive amount of disk utilization.

Hi Folks,
I understand that Oracle doesn't support their products 100% on non Oracle VMs, but I thought I might take a stab at it.
I decided to stick with a simple installation of Oracle Grid Control running on a Windows 2003 R2 32 bit os, here are the steps I took.
1. Run Guest OS Windows 2003 R2 32 bit on a Windows 2008 x64 running Hyper-V (Yes I know why not EL5 running XEN, long story)
2. Install Grid Control with Database and Agent versions 10.2.0.2.1
3. Patch agent and oms to 10.2.0.5.0
4. Some minor issues, but managed to get by those.
- First off EM Website shows down, got to take a look at that, probably need to fix the beacon, not sure!
Problem:
- Grid shows that the host running em is over 100% disk utilization.
- According to Metalink this is a known bug in Windows 2000 Performance Counters (not 2003?)
- More specially Microsoft KB article Q310067.
- Metalink Doc Id: 303788.1
- Note, I'm running 2003 on a Hyper-V Guest, so anything can go wrong!
The specific error is:
Metric               Disk Device Busy (%)
Disk Device               0 C:
Severity               Critical
Alert Triggered          Jun 3, 2009 7:57:54 PM
Last Updated          Jun 4, 2009 3:48:48 PM
Acknowledged          No
Acknowledged By     n/a
Message               Disk Utilization for 0 C: is 587.86%, crossed warning (80) or critical (95) threshold.
More info:
- Guest is running on a Dual Quad Core Xeon System with 16 GB of RAM
- Guest has dedicated 4096MB of ram
- Guest has dedicated 2 CPUS
- Guest is configured with a Virtual Disk (specifically partition c:\) to be on local Hyper-V disk array
- Windows 2008 Hyper-V host disk array is in a RAID 5 configuration running 10k SAS drives
- Windows 2008 Hyper-V host utilization is literary at most 5% (current is 1%)
- Windows 2008 Hyper-V disk utilization according to graphs is showing 100KB/s usage (less than 1%)
Temporary solution is to turn off the metric, but not sure if that's such a good idea.
- Note that 11g EM and 10g EM running on Hyper-V server had the same issue.
- Note that 11g EM and 10g EM running without visualization had no issues.
Any thoughts?

It may be related to Bug 8677212: BACKUP INFORMATION FOR SOME DATABASES SHOWS INCORRECTLY
Although bug info says it for HP-UX, I've also seen the same problem on Grid Control 10.2.0.5 running on Solaris.
You may want to apply 10.2.0.5.4 Grid Control Patch Set Update (PSU) [ID 1139563.1] to fix it.

Why is Mission control showing me icons instead of smaller representations of active apps?

Why is Mission Control looking like this? If I put away Mission Control and reopen it things change a little, the tiny white window in the middle dissapears. I've updated, restarted etc etc.. Any ideas?

http://www.apple.com/feedback/macosx.html
I have never seen this before. which MBP are you on???
This could be an issue with a widget in you dashboard or a plugin in safari.
https://discussions.apple.com/thread/3251015?start=0&tstart=0
this link (the poor chum no one replied to him) https://discussions.apple.com/thread/3251015?start=0&tstart=0 would suggest a safari plugin you may have on. turn off all your extensions in safari>preferences>extensions for a second and restart or just close safari and reopen (restart if this doesn't do anything)
here's a wild idea, and not sure if it'll do anything, have you tried to relaunch finder? hold option and then right click the finder icon and hit relaunch.
have you tried reseting safari?
either way send this to apple.
You may have to reinstall lion.

Why does volume control show during video playback

I am playing a tutorial video for Cubase and I get a volume indicator which stays right in the middle of the screen and blocks some content while playing back the video. I don't need it and would like to know how to turn it off, but I have not found the secret setting to do so. Is anyone able to point me in the right direction. All the tutorials from this company do the same thing on my ipad. When i close the app the volume control goes away with it. There do not seem to be any internal settings within the app that would allow me to select on or off of this volume control display, and the general settings tab did not help either.
Thanks for any help you can offer. I am trying to remember the name of the company that created the video. I am afraid if I close this window to open ithe app I will lose my post, so I will post this much and try to find the company name and add it to a later post.
Steve

Macprovideo.com is the name of the company that produces these tutorials.
I am replying to my own post to give further info.

Grid Control 에서 새 target node를 추가한 이후에 기존OMS와 새 Agent 간의 HeartBeat fail 해결방

Grid Control 에서 새 target node를 추가한 이후에 기존OMS와 새 Agent 간의 HeartBeat fail 해결방법
=========================================================================
다음은 Grid Control 을 설치한 이후에 node를 관리해 오다가 새로운 관리할 Target node를
추가한 이후에 Grid Control 이 있는 node의 OMS와 새로 추가한 node의 Agent가 HeartBeat 통신
실패 시에 해결책을 소개하고 있습니다.
Problem Description
Grid Control 에서 새로운 node를 추가한 다음에 그 새로운 node 에서
emctl status agent 명령 수행 시 다음과 같은 에러가 발생합니다.
Environment :
mesdev01 : 새로 추가한 Agent가 있는 node명
mesdev02 : 'Central Grid Agent' 존재 & 'Repository database가 존재하는 node'
새로 추가한 node에서 아래와 같이 emctl status agent 명령을 수행합니다.
그런데, OMS에 대한 HeartBeat fail 이 발생했음을 알 수 있습니다.

원인
이 에러가 발생하는 원인은 새로 추가한 database의 Agent process가 GRID Control 이
install된 main server의 OMS와 연결되지 않기 때문인데, 이렇게 새로운 node를 추가한 이후에
수행해줘야 할 절차가 있습니다.
OMS_HOME/sysman/log 의 secure.log 를 확인해 보면 OMS is "secure locked" 라는 에러가 보입니다.
The OMS is "secure locked", then the agent also needs to be secure.
[ 사전 check 사항 ]
1. 두 node 모두 DNS server에 등록되어 있는지 확인한다.
2. 두 node 모두 쌍방 간에 /etc/hosts file에 서로의 ip address와 hostname을 넣어준다.
위 두가지 check 사항이 충족된 경우에도 발생한다면 새로 추가한 node 쪽에서 자신의 정보를
OMS(즉, Repository node) 에게 정보를 upload하지 않았기 때문입니다.
Upload를 하는 방법은 간단하게 아래와 같은 emctl upload agent 라는 명령으로 가능합니다.
emctl upload agent
Upload를 하게 될 때 그 정보는 XML 형태로 중앙 Repository에 저장됩니다.
Solution Description
아래 절차 중에 1번만 Grid Control이 설치된 OMS server에서 수행을 하고,
2번~7번까지는 새로 추가한 Agent node에서 수행합니다.
1. On oms server: (Grid Control 이 설치된 서버에서 수행)
<OMS_HOME>/bin/emctl status oms -secure
OMS node인 mesdev02 node에서 우선 emctl status oms -secure 를 수행합니다.

Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
Stopping agent ... stopped.
3. Verify no residue emagent processes running:
이와 같은 명령으로 남아 있는 emagent process가 있는지 확인합니다.
ps -ef|grep emagent
[mesdev01:/oracle/app/oracle/product/agent10g/bin]ps -ef|grep emagent
oracle 4353 3125 0 16:19:34 pts/tb 0:00 grep emagent
4. If running secure please resecure agent on :
<AGENT_HOME>/bin/emctl secure agent
emctl secure agent 를 수행하는 목적은 모든 agent에 대해서 secure communication 을
하기 위해 필요합니다.
[ 주의사항 ]
emctl secure agent 명령은 Grid Control installation 과정에서
--> 'Specify Security Options' 단계에서
--> Management Service Security 항목에서
--> OMS와 함께 Secure Communication을 하고자 하는 agent에 password 설정을 하는데,
--> Require Secure Communication for all agents 를 check 표시하였다면
install 이후에 아래와 같이 emctl secure agent 명령을 수행하여야 합니다.

Status Pending on Grid Control

Hi,
On the Grid Control -> All Targets Type=Cluster
I have the "Status Pending" on my target Cluster.
All the nodes are up as also as all the agents, instances, etc...except the cluster that appears to be "Status Pending".
I tried to restart all the agents and refreshing the configuration, but the "status pending" remains.
Anyone has any idea?
Thanks.
Best regards,
José Carlos

Grid Control server can connect to target database 1521(listener port)?
Grid Control server -> target database:1521
Grid Control server -> target database:agent port (3872)
target database -> Grid Control server: 4889 ; (upload agent file)
http://download.oracle.com/docs/html/B12013_03/firewalls.htm
Please check your connect
After that clear state
1. Stop the agent on the target node
emctl stop agent
2. Delete any pending upload files from the agent home
cd $AGENT_HOME/<hostname>/sysman/emd/
rm -r state/*
rm -r collection/*
rm -r md/upload/*
rm lastupld.xml
rm agntstmp.txt
rm blackouts.xml
3. Issue an agent clearstate
emctl clearstate agent
4 Start the agent
emctl start agent
5. Force an upload to the OMS
emctl upload agent
Good Luck

Hi,
I just came across the same problem.
In my case, I hit this issue while trying to reinstall Oracle EMCC 12g.
Since previous installation failed, I decided to start from the beginning again but I am now hitting this.
Before trying to reinstal, I dropped SYSMAN and a few other users created on the provided DB.
Did you solve this issue?
I believe I may have not "clean up" the database properly. Which would be the right way of wiping out the DB without actually rebuild it again?
Thanks
Angel
