Editing EM12c Jobs in Bulk

I recently received requests for suggestions on how to edit EM12c jobs in bulk. The two examples that were presented to me were:

  1. Change the start time of 70+ jobs
  2. Change the oracle home path in 80+ RMAN script jobs

So how do we do this?

EM12c Release 4: Job System Easter Eggs - Part 1

So you just installed a new EM12c R4 environment or upgraded your existing EM environment to EM12c R4. Post upgrade you go to the Job System activity page (via Enterprise->Job->Activity menu) and view the progress details  of a job. Well nothing seems to have changed, its the same UI, the same multi-page drill down to view step output, same no. of clicks, etc. Wrong! In this two part blog post, i talk about two Job System Easter Eggs (hidden features) that most of you will find interesting. These are:

  1. New Job progress tracking UI
  2. Import/Export of job definitions

So before i go any further, let me address the issue of why are these features hidden? As we were building these features, we realized that we would not be ready to ship the desired quality of code by the set dates. Hence, instead of removing the code, it was decided to ship it in a disabled state so as not to impact customers, but still allowing a brave few to experiment with it and provide valuable feedback.

1.  New Job Progress Tracking UI

The job system UI hasn't changed much since its introduction almost 10 years ago. It is a daunting task to update all the job system related UIs in a single release, and hence we decided to take a piecemeal approach instead. In the first installment, we have revamped the job progress tracking page.

Old Job Progress Tracking UI

The current UI, as shown above, while being very functional, is also very laborious. Multiple clicks and drill downs are required to view the step output for a particular target. Also, any click leads to complete page refresh, which leads to wastage of time and resources. The new UI tries to address all these concerns. It is a single page UI, which means no matter where you click, you never leave the page and thus never lose context of the target or step you where in. It also significantly reduces the no. of clicks required to complete the same task as in the current UI. So lets take a look at this new UI.

 First, as i mentioned earlier, you need to enable this UI. To do this, you need to run the following emctl command from any of the OMS:

./emctl set property -name -value true

 This command will prompt for the sysman password, and then will enable the new UI.

NOTE: This command does not require a restart of the OMS. Once run, the new UI will be enabled for all user across all OMSes.

EMCTL Output

Now revisit the job progress tracking page from before. You will be directed to the new UI.

New Job Progress Tracking UI

There are in all 6 key regions on this new single page job progress tracking UI. Starting from top left, these are:

  1. Job Run Actions - These are actions that can be performed on the job run like suspend resume, retry, stop, edit, etc.
  2. Executions - This region displays all the executions in the job run. An execution, in most cases, represents a single target and hence runs independently from other executions. This region thus shows the progress and status of all executions in a single view. The best part of this region is the column titled 'Execution Time'. The cigar chart in this column represents two things - one, the duration of the execution, and two, the difference in start times. The visual representation helps in identifying runaway executions, or just compare execution times across different targets. The Actions menu allows various options like start, stop, debug, delete, etc.
  3. Execution Summary - Clicking on an execution in the above region, paints the area on the right. This specific region shows execution summary with information like status, start & end date, execution id, command, etc
  4. Execution Steps - This region lists the steps that make up the execution.
  5. Step Output - Clicking on a step from the above region, paints this region. This shows the details of the step. This includes the step output and the ability to download it to a text file.
  6. Page Options - We imagine that learning any new UI takes time, and hence this final region provides the option to switch between the new and the classic view. Additionally, this also allows you to set the auto refresh rate for the page.

Essentially, considering that jobs have two levels - executions and steps, we have experimented with a multi-master style layout. EM has never used such a layout and hence there were concerns raised when we chose to do so.

Master 1 (region 2) -> Detail 1 (regions 3, 4, & 5)

Master 2 (region 4) -> Detail 2 (region 5)

In summary, with this new UI, we have been able to significantly reduce the no. of clicks required to track job progress and drill into details. We have also been able to show all relevant information in a single page, thus avoiding unnecessary page redirection and reloads. I would love to hear from you if this experiment has paid off and if you find this new UI useful.

In the next part of this blog i talk about the new emcli verbs to import and export job definitions across EM environments. This has been a long standing enhancement request, and we are quite excited about our efforts.

EM12c: Using the LIST verb in emcli

Many of us who use EM CLI to write scripts and automate our daily tasks should not miss out on the new list verb released with Oracle Enterprise Manager The combination of list and Jython based scripting support in EM CLI makes it easier to achieve automation for complex tasks with just a few lines of code. Before I jump into a script, let me highlight the key attributes of the list verb and why it’s simply excellent!

1. Multiple resources under a single verb:
A resource can be set of users or targets, etc. Using the list verb, you can retrieve information about a resource from the repository database.

Here is an example which retrieves the list of administrators within EM.
Standard mode
$ emcli list -resource="Administrators"

Interactive mode
The output will be the same as standard mode.

Standard mode
$ emcli
Enter password :  ******

The output will be the same as standard mode.

Contents of script
print list(resource="Administrators",jsonout=False).out()

To get a list of all available resources use
$ emcli list -help

With every release of EM, more resources are being added to the list verb. If you have a resource which you feel would be valuable then go ahead and contact Oracle Support to log an enhancement request with product development. Be sure to say how the resource is going to help improve your daily tasks.

2. Consistent Formatting:
It is possible to format the output of any resource consistently using these options:


  This option is used to specify which columns should be shown in the output.

Here is an example which shows the list of administrators and their account status
$ emcli list -resource="Administrators" -columns="USER_NAME,REPOS_ACCOUNT_STATUS"

To get a list of columns in a resource use:
$ emcli list -resource="Administrators" -help

You can also specify the width of the each column. For example, here the column width of user_type is set to 20 and department to 30.
$ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE:20,COST_CENTER,CONTACT,DEPARTMENT:30"

This is useful if your terminal is too small or you need to fine tune a list of specific columns for your quick use or improved readability.

  This option is used to resize column widths.
Here is the same example as above, but using -colsize to define the width of user_type to 20 and department to 30.
$ emcli list -resource=Administrators -columns="USER_NAME,USER_TYPE,COST_CENTER,CONTACT,DEPARTMENT" -colsize="USER_TYPE:20,DEPARTMENT:30"

The existing standard EMCLI formatting options are also available in list verb. They are:
-format="name:pretty" | -format="name:script” | -format="name:csv" | -noheader | -script

There are so many uses depending on your needs. Have a look at the resources and columns in each resource. Refer to the EMCLI book in EM documentation for more information.

3. Search:
Using the -search option in the list verb makes it is possible to search for a specific row in a specific column within a resource. This is similar to the sqlplus where clause. The following operators are supported:
           is (Must be followed by null or not null)

Here is an example which searches for all EM administrators in the marketing department located in the USA.
$emcli list -resource="Administrators" -search="DEPARTMENT ='Marketing'" -search="LOCATION='USA'"

Here is another example which shows all the named credentials created since a specific date. 
$emcli list -resource=NamedCredentials -search="CredCreatedDate > '11-Nov-2013 12:37:20 PM'"
Note that the timestamp has to be in the format DD-MON-YYYY HH:MI:SS AM/PM

Some resources need a bind variable to be passed to get output. A bind variable is created in the resource and then referenced in the command. For example, this command will list all the default preferred credentials for target type oracle_database.

Here is an example
$ emcli list -resource="PreferredCredentialsDefault" -bind="TargetType='oracle_database'" -colsize="SetName:15,TargetType:15"

You can provide multiple bind variables.

To verify if a column is searchable or requires a bind variable, use the –help option. Here is an example:
$ emcli list -resource="PreferredCredentialsDefault" -help

4. Secure access
When list verb collects the data, it only displays content for which the administrator currently logged into emcli, has access.

For example consider this usecase:
AdminA has access only to TargetA.
AdminA logs into EM CLI
Executing the list verb to get the list of all targets will only show TargetA.

5. User defined SQL
Using the –sql option, user defined sql can be executed. The SQL provided in the -sql option is executed as the EM user MGMT_VIEW, which has read-only access to the EM published MGMT$ database views in the SYSMAN schema.

To get the list of EM published MGMT$ database views, go to the Extensibility Programmer's Reference book in EM documentation. There is a chapter about Using Management Repository Views. It’s always recommended to reference the documentation for the supported MGMT$ database views.  Consider you are using the MGMT$ABC view which is not in the chapter. During upgrade, it is possible, since the view was not in the book and not supported, it is likely the view might undergo a change in its structure or the data in it. Using a supported view ensures that your scripts using -sql will continue working after upgrade.

Here’s an example
  $ emcli list -sql='select * from mgmt$target'

6. JSON output support   
JSON (JavaScript Object Notation) enables data to be displayed in a collection of name/value pairs. There is lot of reading material about JSON on line for more information.

As an example, we had a requirement where an EM administrator had many 11.2 databases in their test environment and the developers had requested an Administrator to change the lifecycle status from Test to Production which meant the admin had to go to the EM “All targets” page and identify the set of 11.2 databases and then to go into each target database page and manually changes the property to Production. Sounds easy to say, but this Administrator had numerous targets and this task is repeated for every release cycle.

We told him there is an easier way to do this with a script and he can reuse the script whenever anyone wanted to change a set of targets to a different Lifecycle status.

Here is a jython script which uses list and JSON to change all 11.2 database target’s LifeCycle Property value.

If you are new to scripting and Jython, I would suggest visiting the basic chapters in any Jython tutorials. Understanding Jython is important to write the logic depending on your usecase.
If you are already writing scripts like perl or shell or know a programming language like java, then you can easily understand the logic.

Disclaimer: The scripts in this post are subject to the Oracle Terms of Use located here.

 1 from emcli import *
search_list = ['PROPERTY_NAME=\'DBVersion\'','TARGET_TYPE=
 \'oracle_database\'','PROPERTY_VALUE LIKE \'11.2%\'']
 3 if len(sys.argv) == 2:
 4    print login(username=sys.argv[0])
 5    l_prop_val_to_set = sys.argv[1]
   l_targets = list(resource="TargetProperties", search=search_list,
 7    for target in l_targets.out()['data']:
 8       t_pn = 'LifeCycle Status'
 9      print "INFO: Setting Property name " + t_pn + " to value " +
      l_prop_val_to_set + " for " + target['TARGET_NAME']
 10      print  set_target_property_value(property_records=
 12   print "\n ERROR: Property value argument is missing"
  print "\n INFO: Format to run this file is <username>
  <Database Target LifeCycle Status Property Value>"

You can download the script from here. I could not upload the file with .py extension so you need to rename the file to before executing it using emcli.

A line by line explanation for beginners:

 1 Imports the emcli verbs as functions
 2 search_list is a variable to pass to the search option in list verb. I am using escape character for the single quotes. In list verb to pass more than one value for the same option, you should define as above comma separated values, surrounded by square brackets.
 3 This is an “if” condition to ensure the user does provide two arguments with the script, else in line #15, it prints an error message.
 4 Logging into EM. You can remove this if you have setup emcli with autologin. For more details about setup and autologin, please go the EM CLI book in EM documentation.
 5 l_prop_val_to_set is another variable. This is the property value to be set. Remember we are changing the value from Test to Production. The benefit of this variable is you can reuse the script to change the property value from and to any other values.
 6 Here the output of the list verb is stored in l_targets. In the list verb I am passing the resource as TargetProperties, search as the search_list variable and I only need these three columns – target_name, target_type and property_name. I don’t need the other columns for my task.
 7 This is a for loop. The data in l_targets is available in JSON format. Using the for loop, each pair will now be available in the ‘target’ variable.
 8 t_pn is the “LifeCycle Status” variable. If required, I can have this also as an input and then use my script to change any target property. In this example, I just wanted to change the “LifeCycle Status”.
 9 This a message informing the user the script is setting the property value for dbxyz.
 10 This line shows the set_target_property_value verb which sets the value using the property_records option. Once it is set for a target pair, it moves to the next one. In my example, I am just showing three dbs, but the real use is when you have 20 or 50 targets.

The script is executed as:
$ emcli subin Production

The recommendation is to first test the scripts before running it on a production system. We tested on a small set of targets and optimizing the script for fewer lines of code and better messaging.

For your quick reference, the resources available in Enterprise Manager with list verb are:
$ emcli list -help

Oracle Enterprise Manager 12c Release 3: What’s New in EMCLI

If you have been using the classic Oracle Enterprise Manager Command Line interface ( EMCLI ), you are in for a treat. Oracle Enterprise Manager 12c R3 comes with a new EMCLI kit called ‘EMCLI with Scripting Option’. Not my favorite name, as I would have preferred to call this EMSHELL since it truly provides a shell similar to bash or cshell. Unlike the classic EMCLI, this new kit provides a Jython-based scripting environment along with the large collection of verbs to use. This scripting environment enables users to use established programming language constructs like loops (for, or while), conditional statements (if-else), etc in both interactive and scripting mode.

Benefits of ‘EMCLI with Scripting Option’

Some of the key benefits of the new EMCLI are:

  • Jython based scripting environment
  • Interactive and scripting mode
  • Standardized output format using JSON
  • Can connect to any EM environment (no need to run EMCLI setup …)
  • Stateless communication with OMS (no user data is stored with the client)
  • Generic list function for EM resources
  • Ability to run user-defined SQL queries to access published repository views

Before we go any further, there are two topics that warrant some discussion – Jython and JSON.

Creating a generic service with emcli ( Oracle Enterprise Manager Command Line Interface )

This blog walks you through the steps to create an Enterprise Manager Cloud Control 12c generic service using the command line API emcli.  At the end of the walk through you will have created a service consisting of;
  • A Host, an Oracle Fusion Middleware Farm, a Database and a Listener
  • HTTP and JDBC Service Test

  • System based performance and usage metrics

  • Service based performance metrics

The following emcli verbs will be used during the exercise;

For this exercise we need to create an XML file consisting of the service test definitions and substitution variables.  The documentation for the create_service verb implies that we can specify separate files in the -input_file parameter, one for the tests and one for the variables; however the documentation is wrong and this is being addressed by (Bug 16329952).

The XML schema definition transaction-template.xsd, contains the definition for both variables and template files, however we recommend that you create a template from an existing service definition using the UI and then use the emcli verb extract_template_tests command to extract a pre-existing template, however if you are comfortable with XML file creation then you can review the examples template.xml and variables.xml.

Creating a template from an existing service definition

Using the UI navigate to Enterprise > Monitoring > Monitoring Templates

Click on the Create button

Click on Target for the Copy Monitoring Settings using option button and enter the name of an existing service that you want to copy and then click Continue.

In the next screen provide the Name of the template and click OK; this will accept the defaults that were provided from the target being copied.

Extract the service test definition from the template using emcli.

emcli extract_template_tests \
    -templateName="myTemplate" \
    -templateType=generic_service \

At this point you need to edit the file myTemplate.xml and ensure that you have the correct values for the substitution variables at the top of the file.

   <variable name="HOST1" value=""/>
   <variable name="PASSWORD1" value="thepassword"/>
   <variable name="PORT1" value="7799"/>
   <variable name="PROTOCOL1" value="http"/>

Create the System and Service definition

Now we can start by creating the system definition.

emcli create_system \
    -name="mySystem" \
    -add_members="EMGC_GCDomain:oracle_ias_farm" \
    -add_members="" \
    -add_members="" \
    -add_members="" \
    -timezone_region="PST8PDT" \

Before we can create the service we must first ensure that we have a beacon to replay the tests.  Create a beacon on an existing agent.

emcli add_target \
    -name="myBeacon" \
    -type="oracle_beacon" \

Now we are ready to create the service.

emcli create_service \
    -name="myService" \
    -type="generic_service" \
    -availType="test" \
    -availOp="or" \
    -timezone_region="PST8PDT" \
    -systemname="mySystem" \
    -systemtype="generic_system" \
    -input_file=template:"/u01/app/oracle/home/myTemplate.xml" \
    -beacons="myBeacon:Y" \

NOTE: Although -timezone_region is optional if it is not specified then the availability computation of the targets will fail and the service and its tests will always show status pending.  Therefore you MUST specify the timezone_region parameter (Bug 16344350).

Additionally if you try to create a service with a name that has been used before it will fail with the error;

Oracle Error :ORA-20233: Target with guid CB9DED6762A117EC708709489C883230 does not exist

This is fixed by Patch 10096491.

We can now create a bunch of Usage and Performance metrics for the service definition that we can alert on.  The key to these metrics is the MGMT$METRIC_COLLECTION view, from this view you will use the METRIC_NAME and METRIC_COLUMN field for the metric definitions for each target type. First we will create the Usage metrics which can only be based on the system definition and not the service.

Let’s add a Usage metric based on the Active HTTP Requests across all targets on the system definition.

emcli set_metric_promotion \
    -name="myService" \
    -type="generic_service" \
    -category=Usage \
    -basedOn=system \
    -aggFunction=AVG \
    -promotedMetricKey="Active HTTP Requests" \
    -metricName="ohs_server" \
    -column="" \
    -depTargetType="oracle_apache" \
    -depTargets="/EMGC_GCDomain/instance1/ohs1" \
    -threshold="125;100;GT" \

Now one for the Average Active Sessions for the database targets in the system.

emcli set_metric_promotion \
    -name="myService" \
    -type="generic_service" \
    -category=Usage \
    -basedOn=system \
    -aggFunction=AVG \
    -promotedMetricKey="Average Active Sessions" \
    -metricName="instance_throughput" \
    -column="avg_active_sessions" \
    -depTargetType="oracle_database" \
    -depTargets="" \
    -threshold="150;125;GT" \

Next the Performance metrics, the first one based on the system definition for CPU Utilization (%).

emcli set_metric_promotion \
    -name="myService" \
    -type="generic_service" \
