DBSNMP User Hangs - RESOLVED

I am experiencing an odd problem. I have 2 identical DBs (10gR2 running on Linux RH EL4). They both have a DBSNMP user. However, I am able to log directly into DB - A as DBSNMP, but this user hangs when I log into DB - B. I have dropped and recreated the user on B, but still it hangs. I verified that the users were identical on both DBs and have checked all of the dump directories and the alert log for messages, but there are none. Any ideas? I need to get this user operational in order to monitor the DB via GRID.
Cheers

I didn't see anything in the trace files or alert log. All I knew was that the sys and system users were the only ones that could successfully log in. Whenever I tried to connect as another user, I was forced to kill the session. When this happened, the following error messages were received:
===============================
Error accessing PRODUCT_USER_PROFILE
Warning: Product user profile information not loaded! You may need to run PUPBLD.SQL as SYSTEM
ERROR: ORA-03114: not conneted to ORACLE
Error accessing package DBMS_APPLICATION_INFO
SP2-0575: Use of Oracle SQL feature not in SQL92 Entry Level.
===============================
I ran PUPBLD.SQL as SYSTEM, but this did not resolve my problem. Another entry in OTN suggested that a re-run of catalog and catproc be done. This resolved the issue.

Changing password of Sysman and DBSNMP users in Oracle 10g (10.2.0.3.0)

Hi,
When i changed my sysman and dbsnmp password, these users are frequently locking.
For sysman password change i do the following steps.
1) emctl stop dbconsole
2) change password of sysman and dbsnmp from sql
3) Post sysman password change to emoms.properties file
4) Post DBSNMP password change in targets.xml
5) emctl start dbconsole.
DBSNMO AND SYSMAN users were locked.
Stop dbconsole again
Unlock the user sysman and dbsnmp
then again restart dbconsole
Sysman user locked
Another thing do we need to have same password for dbsnmp and sysman
Regards,
irfanb146

Now Sysman and DBSNMP users are unlocked after i made the password of sysman change again and they are not locking.

Hi,
Ok i will do in future.
I did as you said but issue is still coming.Now the error is bit different in the log file For this same error i found solution in meta doc id 337260.1 for exact error In the solution i have to to set the value as below but it has already same value.
Error:
CONFIG: SQLEngine created successfully and connected
May 29, 2010 5:03:06 PM oracle.sysman.emcp.DatabaseChecks validateUserCredential
CONFIG: Failed to update account status.
oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-01034: ORACL
E not available
Solution:
In order to fix the Invalid username/password message
Check the profile limit for the users SYSMAN, DBSNMP and MGMT_VIEW
select u.username, u.profile, p.resource_name, p.limit
from dba_profiles p, dba_users u
where p.profile=u.profile
and u.username in ('SYS', 'SYSMAN','DBSNMP','MGMT_VIEW')
and p.resource_type = 'PASSWORD'
order by u.username, p.resource_name;
If the value of LIMIT for PASSWORD_VERIFY_FUNCTION is not NULL:
Change the password so that it meets the function requirements.
If the value of LIMIT for PASSWORD_REUSE_MAX is not UNLIMITED:
Change the password so that it is different from a password that has already been used the number of times set in PASSWORD_REUSE_MAX.
Or
Change the value of LIMIT for PASSWORD_REUSE_MAX to UNLIMITED for the profile.
Below output of 1st query:
USERNAME     PROFILE     RESOURCE_NAME     LIMIT
DBSNMP     DEFAULT     FAILED_LOGIN_ATTEMPTS     UNLIMITED
DBSNMP     DEFAULT     PASSWORD_GRACE_TIME     UNLIMITED
DBSNMP     DEFAULT     PASSWORD_LIFE_TIME     UNLIMITED
DBSNMP     DEFAULT     PASSWORD_LOCK_TIME     .0006
DBSNMP     DEFAULT     PASSWORD_REUSE_MAX     UNLIMITED
DBSNMP     DEFAULT     PASSWORD_REUSE_TIME     UNLIMITED
DBSNMP     DEFAULT     PASSWORD_VERIFY_FUNCTION     NULL
SYS     DEFAULT     FAILED_LOGIN_ATTEMPTS     UNLIMITED
SYS     DEFAULT     PASSWORD_GRACE_TIME     UNLIMITED

Password for the DBSNMP user Keep Changing

Hi ..
I see frequent change in the password for the DBSNMP users, as a result facing metric collection error for the target instances. Please advise what could be the reason for it. I have created a separate profile for the this user and changed the failed_login_attempts to Unlimited.
Thanks.

Thanks.Also set password expiry date to unlimited otherwise password will expire.
You can check expiry date , account_status from dba_users .

DBSNMP User Password

[Version 10.2.0.2]
Problem: I am trying to recreate the repository for the enterprise manager and I continue to receive invalid/username password errors for the dbsnmp user.
What I've done so far:
1) I've modified the monitoring_profile so that the account will not expire or lock.
2) Using the emca I've dropped the repository AND configuration files
3) I've logged into the database using the new password.
4) I've bounced the database.
5) When I go to the $ORACLE_HOME/sysman/emd/targets.xml file the file only contains an empty Targets element.
Any suggestions on how I can recreate the repository or get beyond this dbsnmp user/password problem?
Thanks in advance.

High Concurrent SQL query of DBSNMP user

OS Linux
DB 11.2.0.2
we have a 12 node RAC box on exadata. We are doing the monitoring through the OEM GRID. In the 12th node we see a high concurrent sql query owned by the DBSNMP user.The concurrency is about 98% and it the top query in that instance. Please suggest me what we shoud do to decrease it.
Below is the query
SELECT s.inst_id, s.name, i.instance_name
FROM gv$active_services s, gv$instance i
WHERE s.name = :p1 AND s.inst_id = i.inst_id

Hi,
We applied the patch 9482559 which was suggested by oracle for a different issue and after applying this patch the high concurrent dbsnmp sql issue is gone.

DBSNMP User suddenly locked

Hi all,
we have a problem with a locked DBSNMP-User.
We are monitoring our databases with Cloud Control 12c. Single-Instance databases are configured with DBSNMP-User, databases in DataGuard-Environment are configured with SYS-User.
Some of DataGuard-databases (production) were cloned on regulary basis for stage, this stage databases should be monitored by DBSNMP, because they are single instances.
Unfortunally the DBSNMP User in the production databases is locked, so monitoring on stage failed.
We unlock DBSNMP on production, but after a while the user is locked again. It seems that the agent connects with dbsnmp and wrong password to the database instead with the configured SYS-User.
Does anybody saw this behaivor? Is this a bug or a feature? Any ideas what to change?
Regards
Jürgen

Hi Sam,
we had similar idea.
But we see this on some database, not only one.
We think, that there is a "clodControl-process" which tries to connect with User DBSNMP not with SYS, what is configured. So it seems, for some processes the user DBSNMP is hard coded and we like to know which processes this are.
Regards
Jürgen

DBSNMP user consumes too much cpu resource

Hello,
for a couple of weeks, I realized that DBSNMP user is always in top user list and it seems at least 15 percent of cpu has being used! as i know this is not normal. is there any one who experienced something like that ? I search for it but couldnt find anything useful.
thanks

HI,
DBSNMP is the account used by Oracle’s intelligent agent to logon automatically to remote servers in order to provide information for presentation via Enterprise Manager. DNSMP has the SELECT ANY DICTIONARY system privilege which can read the passwords from SYS.USER$ and enables the account to do its work for the Intelligent Agent. The problem is that an Attacker could log on to Oracle as DBSNMP especially if the default password has not been changed. The attacker could then read the password hashes from SYS.USER$.
dbsnmp is used by OEM as Intelligent agent for nodes discovery
Can you please restart dbconsole service and check.

Microsoft Exchange Server 2013 - Windows Server 2013 Standard - When logging in user hangs on - "Applying user settings" message

Dear colleges,
Thanks in advance for viewing and suggesting!
Now for whatever reason it is the XCHG server is not responsive at all when launching ECP from the other computer on the domain. When logging in to the virtual box EXCH server is hosted on it hangs on the "Applying user settings" message for
an about an hour when finally logged in 4 or 5 XCHG services won't start... I don't remember exactly which ones - "...Mailbox Transport..." is one of them.
I read about the similar being an issue with Win 2008 R2 and EXCH server 2010, and followed the advice that I needed to add some entries to the registry - didn't help, disabling IP6 (which by the way makes no sense as XCHG needs one) - still didn't help.
Would you suggest to rebuild virtual server and reinstall EXCH all together as troubleshooting Windows issues may be lengthy?
Thanks!

Thanks folks! I think I have a clue what's going through don't know how fix it yet.
The problem is with DNS unable to resolve my main domain vwc.local. It makes some XCHG services to time out when starting. The error messages in the event log suggest about domain being unavailable
to contact.
When I tried resolving vwc.local with nslookup and ping it pinged THE OLD domain's IP address. When I setup server at home I specified this old ip address but changed it to a new one when I
moved box to the office. In the office everything worked very well - I introduced office's desktops to vwc.local, built a virtual box, introduced it the domain as well. Everything was good up until I started messing with XCHG. Now the domain is not resolvable
even though I made to be pinged to the new address by updating network adapter settings at the main server by selecting some checkboxes. But the vwc.local is still not available at VW where the XCHG is hosted on. When I open Server Manager/AD DS/AD DS
manager it gives me an error message about the DC being unavailable to contact.
How do I fix this domain mess now? Now I have 3 issues to deal with:
1. My remote desktop stopped working due to trial expiration even though I licensed server for 5 RDSCALs. This is a known issue with RDS and AD DS roles hosted on one physical box. Nobody seems
to know the step by step solution to the issue. I just got bunch of recommendations that I already followed. It looks like I need to call Microsoft and have them deal with their buggy software altogether.
2. DNS/domain issues described below. Something very weird. May I try re prepping the AD DS on the main server. I didn't try that may be I will.
3. XCHG not receiving messages from the outside.
:) Let's just focus on DNS/domain for a moment.
Thanks in advance!

Sp user not resolving in the people picker SharePoint 2010

Hi All,
i have an account domain/bimoffice, this account resolves in all the site collections but only in one site collection is does not so not able to give permission to him
for example
http://acm/sites/gis works !
http://acm/sites/ww - works!
http://acm/sites/op - not works!
how to fix this?

so do you have problem only with single account in http://acm/sites/op, or other users are also not resolved?
One more idea: is user domain/bimoffice still active in AD? May be it was active before and used on other site collection, but after that it was disabled and can't be resolved on new site http://acm/sites/op anymore.

How to create dbsnmp user manually?

Does anyone know how to create dbsnmp manually?

Sadly, you do not include the database version.
Assuming 10g, you want to use emca with the 'repos'
option. Many samples to be found by searching the
forum using keywords 'emca report'lol. Hans must have a very sad day.
For OP, you should have the user created by default, it's just locked. err, assuming you are on 10g.
This script catsnmp.sql has the actually create statement. But it should have been called by catalog.sql

Guest user hang

Since a while (before Mavericks), when my main account is logged and one of my children want use the guest account, my 2013 iMac 27" hang in the loggin process.
If I do cancel, it goes back to sleep mode. When I wake up the iMac, it's at the same login step.
I need to do a hard reboot to get rid of this problem.
Any clues?

had updated, ran disk utility (rep. perm.) --restarts in between doing the bigger things.
User - movies - imovie projects: the preview of the first offending project shows up fine for the project and lists 59.3MB for size, so no '0' issues there. If I 'show package contents' on the project...
the 'Proxies' folder is not there on the project w/ issues vs. the ones that are fine.. (I had tried deleting the ones that beach balled so I know a few of the good vs. ones w/ issues---then decided to time machine them back in hopes of saving and finding a resolution)
Could this 'Proxies' thing be that which determines the synapse? And how would I reconnect if so?
ideas anyone?
