PI 7.1 - Message Monitoring - Adapter Engine (Database Overview)

Hi Friends,
In Message Monitoring --> Adapter Engine --> Database (Overview) is not working. It throws the following error message.
no_connection Exception Message: RemoteException in Method: CentralViewManager: getIProfiles( IApplication, boolean ). Communication-related failure. Message: java.rmi.RemoteException: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.wsdl2java.ClientProtocolException: An error occured while reading data from the destination sap.com/com.sap.aii.af.service.profile.proxy/com.sap.aii.af.service.statistic.proxy.ProfileProcessor/basicPort_Document.

The error was Internal error during the decryption process...
But, Adapter Engine --> Database option is working. What could be the problem ?
Kindly clarify, friends.
Kind regards,

Hello friend,
May be it is related with connection problem check with your basis people .

Monitoring Physical standby database through OEM

HI ,
We are monitoring Physical standby database through OEM and we monitor from console using SYS user
As per our company policy we change our sys password every month so after change it we need to change SYS password from console also
so is any way we can change SYS password on console using command line utility? if yes then please give us the command
Thanks

we monitor from console using SYS userYou have to monitor it using a SYSDBA user not necessarily SYS. So you can create a user e.g. SYS_MONITOR which has different policy than SYS. Although it is best to change that password on regular bases too, maybe every 3 months.
so is any way we can change SYS password on console using command line utility?I don't get your question. Are you asking if it is possible to change the monitoring username/password using some command line utility? If so, I haven't heard of such tool. But there could be a package like MGMT_TARGET which you can manipulate the credentials if you know how to use it.

Can Grid control 11g monitor Oracle 9i database

Can Grid control 11g monitor Oracle 9i database? This is on Linux5.7
Thanks for the help
s.

Yes but Enterprise Manager 11.1 Grid Control requires the 11.1 Agent.
Then go to the Targets tab, then Databases. It should self-discover the 9i database.
Also see Advanced Uses of Oracle Enterprise Manager 11g

Grid Control supplies a common, standard interface to set up and manage Oracle Data Guard for Oracle Database 9i, 10g and 11g databases

Solution manager and CCMS monitoring of remote database

I have Solution Manager 7 SP Basis 6 installed. I have oracle remote databases connected successfully. Under DBCockpit I see the instances I want to monitor. I can see the backup, tablespaces, etc. These remote instances are SAP Portal JAVA only version 7 but under the dbcockpit alerts only shows alert monitor. The database check and check conditions are in white. Is there a way to see these and be able to report on them? The CCMS tree under the local solution manager also shows these connected remote instances but they are also white in color as if inactive. All CCMS agents and saposcol are running perfectly on the remote systems. The stats tables have been built, the synonyms for the solution manager are in place. What am I missing?

Hi,
Please download that attachment "scripts_1139623.sar" provided in SAP Note 1139623 - Using transaction RZ20 to monitor remote Oracle databases.
Upon extraction of scripts_1139623.sar the following files you will get.
rz20_nonabap.sql
dbcheckora10_oltp.sql
dbcheckora.sql
Then Perform the below mentioned Steps to resolve your issue.
Step 1: Create tables DBCHECKORA and DBMSGORA:
sqlplus SAPSR3DB/<pwd>
SQL> @rz20_nonabap.sql
Step 2: Fill the table DBCHECKORA:
sqlplus SAPSR3DB/<pwd>
SQL> @dbcheckora10_oltp
Step 3: Create the synonyms (as user ora<sid>):
brconnect -u / -c -f crsyn -o SAPSR3DB
sqlplus "/as sysdba"
CREATE PUBLIC SYNONYM SAP_DBSTATC FOR SAPSR3DB.DBSTATC;
CREATE PUBLIC SYNONYM SAP_DBCHECKORA FOR SAPSR3DB.DBCHECKORA;
CREATE PUBLIC SYNONYM SAP_DBMSGORA FOR SAPSR3DB.DBMSGORA;
Step 4: Grant Privileges for OPS$<SID>ADM User for the above created Tables
sqlplus "/as sysdba"
grant all on SAPSR3DB.DBSTATC to OPS$<SID>ADM;
grant all on SAPSR3DB.DBCHECKORA to OPS$<SID>ADM;
grant all on SAPSR3DB.DBMSGORA to OPS$<SID>ADM;
grant all on SAPSR3DB.DBSTAIHORA to OPS$<SID>ADM;
grant all on SAPSR3DB.DBSTATHORA to OPS$<SID>ADM;
grant all on SAPSR3DB.DBSTATIORA to OPS$<SID>ADM;
grant all on SAPSR3DB.DBSTATTORA to OPS$<SID>ADM;
commit;
Step 5:
Now after successful execution of above mentioned Steps , in DBACOCKPIT (system configuration), try to save the Remote DB entry with "Collect Alert Data". It will be saved without any error.
If you find any errors, post the error contents as a reply of this thread message.

How to monitor Amazon RDS databases

Hi All,
We are trying to monitor Amazon RDS databases with Oracle Enterprise Manager Cloud Control. We have installed the Amazon Plug in, and now trying to follow the document http://download.oracle.com/otn/java/oem/emaws.pdf?AuthParam=1370564532_780559001200353ecd9e646d78bafa9a but we are stuck with configuring the SSL component.
Does anyone know how/where to get the information to complete the following command, in particular StoreLocation?
./emcli set_monitoring_credential \
-set_name="SSLTrustStoreCredentialSet" \
-target_name="demodb" \
-target_type="AmazonRDSService" \
-cred_type="StoreCredential" \
-attributes="StoreLocation:<truststore location>;
StoreType:JKS;StorePassword:<password>"
Any help would be appreciated.
Thanks
Les

Well, remember you are trying to connect to it with a
database user to monitor it. So, whether manage or
monitor, you need to create a Data Guard entry for
it. This I have done and it works for me.i did that too but get
a) metric collection errors if connecting as sydba or
b) instance down if connection as non-sysdba
targets->database shows both databases, primary and standby as primary and standby.
targets->database->primary->dataguard shows the standby under "standby databases".
i didn't create these entries, that was done by GridControl during discovery.
it seems that GridControl tries to collect all metrics even if the database is running as standby.
which user do you use to connect to the standby, sysdba or non-sysdba?
thanks & regards,

Interesting things to monitor via syslog/snmp etc on 5508?

Hi all,
We don't use Cisco prime for network monitoring. I'm interesting and monitoring and alerting on any potential wireless performance or security issues.
Has anyone got any suggestions for interesting things to monitor on a 5508 WLC? We have a range of AP's some of them CleanAir and some older.
We can monitor or alert on specific syslog messages, snmp traps, or snmp gets.
Has anyone got any favorite things the like to monitor?

This is a tough one, specially if you do not have cisco wireless management system (like WCS or Prime)
Here is WLC system message guide, you may need to go through it & find what to look at depend on your interest (there are so many)

Monitoring/debug the database connection process

Hi,
I am trying to define a new database connection using the JDBC-ODBC Bridge (trying to connect to a legacy apps), and keep getting an error message from the ODBC driver manager, which work perfectly fine outside the JDev environment.
Is there a way for me to monitor/debug the database connection process, prior to a successful test connection, in order for me to find out exactly where/what the problem is?
Thanks for the help,

Monitoring an Oracle Database Appliance w/Ops Center?

Is anyone using Ops Center to monitor an Oracle Database Appliance?:
http://www.oracle.com/us/products/database/database-appliance/overview/index.html
I'm looking for a monitoring solution that won't require a lot of 'expect' gathering/parsing work.

A stack trace for the exception would be very useful!
Anyway, perhaps you should check that the username/password specified in the code correspond to those required to access the database (username = "Kotzwinkle", password = "whatever"). Sometimes you can get away with specifying these in the ODBC data source, in which case you shouldn't pass them to the getConnection method.
Hope this helps.

Sharepoint databases are not getting monitored including config database

Hi,
I've imported the MP for Sharepoint server 2010 and i have also imported IIS and SQL server 2008 MP before importing SP MP. I am able to successfully discover the farm and the web applications
and the services are being monitored. Somehow the sharepoint Databases (both content and Config) are not monitored.
We are also monitoring one more database server which is not related to the sharepoint and the databases in this external server are monitored. I am not sure what i am missing for the sharepoint
databases alone.
Can somebody please help to figure this out? Thanks!
OS: Windows 2008 R2
SQL server: 2008 R2
Thanks,
Jegu

The guide also suggests importing IIS and SQL server management pack. And it's also talking about duplicate alerts for some specific components but not exactly with the databases. I suppose Config
and content databases are part of SharePoint 2010 and that's why there are sections called ConfigDatabases and ContentDatabases within SharePoint Management Pack and also a in a diagram view. It's clearly shows it's in "not monitored" state and I believe something
is missing somewhere. The Guide is not designed for troubleshooting any of these issues.

How to monitor oracle 11g database sessions on Windows 2008 server?

Hi Experts
How to monitor the Oracle 11g database sessions on Windows 2008 server (other than SQL Developer tool), which procedure or query is taking more time with Java application.

Recently i found this tool- myorasql on the net to monitor the performence of database, easy to setup and check the performence. i never tested it but seems impresive. It is free and i think it would be use ful to you.

You can also use Quest - Toad or sqlplus if you are very good at sql commands and all dictionary tables or OEM/EM grid if it is configured .

Publication is not listed in reolication monitor after manual database failover

Hi All,
I have three servers using which I have configured database mirroring and transactional replication with pull subscription.
ServerA--Publisher/Distributor/principal
ServerB--Subscriber
ServerC--Mirror
After failover now ServerB pulls the data from ServerC which is the new Principal andI have set the -PublishfailoverPartner as ServerC .
After the failover is performed I see subscriber is pulling transactions from ServerC and transactions are getting replicated but I cannot see the publication listed under new publisher(ServerC) nor under old publisher ServerA from replication
monitor.
What is the reason I cannot see the publications from replication Monitor. How will distributor know that ServerC is now the publisher.
Also I got the error when I executed below command for distribution agent. But still transactions are getting replicated after failover.
exec
sp_add_agent_parameter@profile_id
= 4,
@parameter_name =
N'-PublisherFailoverPartner',
@parameter_value =
N'ServerC
Msg 21806, Level 16, State 1, Procedure sp_MSvalidate_agent_parameter, Line 63
parameter -PublisherFailoverPartner. The value must be an integer. Verify that replication is installed properly and that sp_add_agent_parameter is invoked with a valid value.The agent profile creation process cannot validate the specified agent parameter
value: the profile_id 4 does not exist or it does not support the
Any inputs will be of great help.

Best Way to monitor standby, primary databases, including alert logs, etc.

Hi, Guys, I finally cutover the new environment to the new linux redhat and everything working great so far (the primary/standby).
Now I would like to setup monitoring scripts to monitor it automatically so I can let it run by itself.
What is the best way?
I talked to another dba friend outside of the company and he told me his shop not use any cron jobs to monitor, they use grid control.
We have no grid control. I would like to see what is the best option here? should we setup grid control?
And also for the meantime, I would appreciate any good ideas of any cronjob scripts.
Thanks

System Monitoring setup: missing database

I would like to set up System monitoring functionality for satellite system in SOLMAN.
The following problems occurred:
1) Missing database component of the system in System Monitoring set up
Usually the system has the following components in System Monitoring set up:
a) SAP Application Server
b) Server <servername>
c) Database <SID>-Database
For my satellite system the Database component c) is missed.
How can this component be activated? The satellite system has MaXDB
2) Missing system entries in tcode RZ20
I miss the entries of the system e.g. Shortdumps Frequency, AbapErrorInUpdate, Shortdumps in tcode RZ20.
How will the system values added into the RZ20?
Thank you very much!
regards
Thom

Solved!
You just need to maintain the DB in SMSY

Monitoring Standard Edition Databases

Hello,
We are currently an all 9i on Solaris shop that is beginning to work on upgrading to 10g and moving to linux 64 bit where possible. As a part of cutting costs, we are moving several production databases from Enterprise Edition to Standard Edition and likely dropping the Database Diagnostics Pack.
From what I can tell from initial testing with 10gR3 Grid Control and Database Control, I am unable to set Notification Rules, blackouts, etc so that I can manage email notifications.
So, is it true that if using Standard Edition databases or Enterprise Edition databases without the Database Diagnostic Pack, I can't email alert and job notifications? Do these same rules apply if I were to do all my monitoring from Database Control instead of Grid Control?
Thanks for any and all feedback.
Terry

So, is it true that if using Standard Edition databases or Enterprise Edition databases without >> the Database Diagnostic Pack, I can't email alert and job notifications?That is true. If you go to Setup --> management Pack Access, at the bottom there is a link to a licencing page which gives you details on all the packs and what they allow you to do.
I've never used database control, so I'm afraid I cannot help you on that one.
