OEM Real-Time Data not Displayed

Hi all,
So I was facing the follwoing situation in a client:
– SYS as SYSDBA passoword working to connect on database.
– Connecting to targets with this credentials working fine.
– However when loading real-time graphs it was simply not working.
– Tried to create manually the named credentials, still not working now with the error:

Listener refused the connection with the following error: ORA-12514, TNS:listener does not currently know of the service requested in connect descriptor.

See what I was getting from database home:

Weird, but hey, the solution was already posted in Grepora!

Ok, I discovered anyway from MOS BUG 28513706 – 13c2EM: DB home page shows Connection Cache with this Cache Name does not exist. it miht be related to connection pools.
Even thought this was closed as not a bug, a learned a new workaround for it:

1. [OMS_HOME]/bin/emctl set property -name use_pooled_target_connections -value false 

2. Restart oms 

[OMS_HOME]/bin/emctl stop oms -all 

[OMS_HOME]/bin/emctl start oms

Hope it helps!
Cheers!

Oracle New Visual Online Tools

Hi all,
So, after a long time of same old documentation style, Oracle started sharing some nice and visual pages for some specifics. Here are 2 examples:

1. Oracle Move to Cloud  (http://www.oracle.com/goto/move)
This one was shown to me by Ricardo Gonzalez, and it’s a GREAT tool if you are planning migrations to Oracle Cloud in general.

The part I like most is where you select the source and destination formats/versions you want and all recommended migration methods are suggested. Of course additional validation on database are required for each method, but it can potentially remind you of things you may be forgetting.

Something else I like very much as well is the section with executive summaries of each migration tool. It’s basically ready for a print screen to put in the slides you are going to present to your boss… 🙂

Also, you have handy some links to papers for the most different migration scenarios, as per:

2. Oracle Database Features: (https://apex.oracle.com/database-features/

NewScreenshot 2019-05-08 às 16.52.14

And by selecting any of the features you can see more info in a very simple way, as per below. By the way, with one click you can be directed to the documentation (the old fashioned one):

Hope you enjoy those as much as I did and hope Oracle continue providing those sort of interfaces to us!

Cheers!

OEM Report: Last 6 month Database Space Usage and Growth [2]

Hey,
So I see you liked the last OEM Report post. But some have asked me for a table with all database space usage something like a summary table for executive view, once the last report gives it by the database, right…

Here it goes:
– I hid the target names for safety, but check on the last column “AVG 6-m Growth”. This is the one you want.
– This obviously needs to be in another Report, once no DB filter is present. So, here is an example of the table and the code:

ExecutiveReport.png

And let me ask you: Would you like to have this view from the ASM Perspective? Like this?

ASM-Growth

Great, right?
The codes for this:

NOTE: We got comments on this regarding the sysdate implicit conversion to timestamp. It worked fine to by, but in case you have any issue, you might want to check over this. Thank you for pointing out, Günter Nowak!

AWS EC2: Custom Functions to Verify Passwords

Hello all!
Looking forward to create password functions on EC2? Easy, we just need to use AWS internal functions for it. Check below an example:

# To create it:

begin
    rdsadmin.rdsadmin_password_verify.create_verify_function(
        p_verify_function_name => 'CUSTOM_PASSWORD_FUNCTION', 
        p_min_length           => 12, 
        p_min_uppercase        => 2, 
        p_min_digits           => 1, 
        p_min_special          => 1,
        p_disallow_at_sign     => true);
end;
/

In case you want to double check the code created, here goes a quick trick: Check on DBA_SOURCE:

col text format a150
  select TEXT  from DBA_SOURCE 
   where OWNER = 'SYS' and NAME = 'CUSTOM_PASSWORD_FUNCTION' order by LINE;

Hope it helps. Cheers!

OEM: HttpConnectionException:Response code:404

Hello all,
So, a client’s OEM Information Report was running and email being sent, but all queries (Report sections) resulting on error:

Unexpected error getting the HTTP response stream while generating report: oracle.sysman.eml.ip.publishJob.HttpConnectionException:Response code:404

 

Weird?
I had a silar issue, as per documented on this post: OEM Information Reports: ORA-00600 [kpndbcon-svchpnotNULL]

This is happening due TCP timeout while executing Report after 5 minutes. By default, Idle Timeout set for Profile parameter (TCP) for the virtual server in F5 is 300 seconds, for example.
I simulated manually execution of each SQL on report and noticed report takes around 8 minutes to run.

What I did? I took some of the slow queries and transformed to a Materialized View with daily refresh.

This was valid in my case because the report runs only once a day. Remember to always check on your own situation. Perhaps an hourly refresh or so is better for you.

Another possibility is to engage the LB admin to modify this parameter by setting a new protocol profile for the virtual server or modifying the existing one.

NOTE: After modifying SLB Values, you may need to restart OMS :

emctl stop oms -all
emctl start oms

Reference?
MOS oracle.sysman.eml.ip.publishJob.HttpConnectionException:Response code:404″ Errors for reports run from EM (Doc ID 2061361.1)

OEM Report: Last 6 month Database Space Usage and Growth

Hello All!
So I had worked in some very useful reports to have in OEM. In next weeks I’ll share some code you may like… 🙂

To create it? Enterprise -> Reports -> Information Reports. There are several nice default reports there you me like.

Now, let’s go to the first Report, as per title:

1. First you Select the Database:

Select_DB.png

2. Then you see the report:

Report3

That’s nice, right?
Here is a report for another database with actual 640GB average growth per month (its expected, once DBSize is over 60TB):

Growth

So, Mat, can you share the queries? Of course:
