Why did we need a Mobile User Interface?

Why don’t we use EM12c Mobile Application?

EM12c Mobile Helps you to manage Incidents

Hard to Navigate

Needs More Features

It shouldn’t be hard to develop it!

Here is The Plan:

My Mobile Application

Views and Procedures in EM12c Repository

• MGMT$TARGET – Target information (name, type, guid, hostname...)

• MGMT$INCIDENTS – All incidents (id, summary, severity, owner, status...)

• MGMT$PROBLEMS – All problems (id, problem key, summary, status...)

• EM_EVENT_MANAGER package – suppress_issue – close_problem

You can find more at Oracle Enterprise Manager Cloud Control Documentation

Oracle Application Express

• Web Applications with SQL and PL/SQL

• Supports Mobile Development using jQuery Mobile

• Fully supported, no cost option of the Oracle Database

• Installed as part of the standard Oracle Database › Needs to be upgraded!

• Right tool for the job!

Oracle Application Express

• Download the APEX (from Oracle.com)

• Easy update/installation:

$ unzip apex_4.x.x.zip -d /home/oracle

$ cd /home/oracle/apex

$ sqlplus / as sysdba

SQL> @apexins.sql SYSAUX SYSAUX TEMP /i/

SQL> @apxldimg.sql /home/oracle

SQL> @apxchpwd.sql

Welcome to Oracle APEX

• Login to: http://yourserver:8080/apex/

Preparations

• Create A Workspace – Workspace will also create a database user

• Give required permissions to schema

• Login to Your New Workspace

grant EXEMPT ACCESS POLICY to youruser;

grant EXECUTE on SYSMAN.EM_EVENT_MANAGER to youruser;

grant SELECT on SYSMAN.MGMT$INCIDENTS to youruser;

grant SELECT on SYSMAN.MGMT$PROBLEMS to youruser

grant SELECT on SYSMAN.MGMT$TARGET to youruser;

Quick Tips for the Application

• While Creating The Application we should select jQuery Mobile Smartphone as User Interface!

• EM12c Users are also DB Users in Repository, so we can use «database users» for authorization.

Quick Tips for the Application

• We can use empty HTML regions to put buttons!

Quick Tips for the Application

• ListView is flexible component you can use for Mobile Applications

List Incidents (Page 2)

• We can use below query to list open incidents:

SELECT i.INCIDENT_ID, i.CREATION_DATE, i.SEVERiTY, t.TARGET_NAME || ': ' || i.SUMMARY_MSG MSG FROM MGMT$INCIDENTS i, MGMT$TARGET t WHERE i.TARGET_GUID= t.TARGET_GUID AND i.OPEN_STATUS = 1 AND i.iS_SUPPRESSED = 0 ORDER BY i.CREATION_DATE DESC;

• We need to link to another page from ListView:

• The above link will call page 4, and set P4_INCIDENT_ID variable in page 4 to INCIDENT_ID of the selected row.

f?p=&APP_ID.:4:&APP_SESSION.::::P4_INCIDENT_ID:&INCIDENT_ID.

List Problems (Page 3)

• We can use below query to list open problems:

SELECT p.PROBLEM_ID, p.CREATION_DATE, p.SEVERITY, t.TARGET_NAME || ' : ' || p.SUMMARY_MSG MSG FROM MGMT$PROBLEMS p, MGMT$TARGET t WHERE p.TARGET_GUID= t.TARGET_GUID AND p.OPEN_STATUS = 1 AND p.IS_SUPPRESSED = 0 ORDER BY p.CREATION_DATE DESC;

• We need to link to another page from ListView:

f?p=&APP_ID.:5:&APP_SESSION.::::P5_PROBLEM_ID:&PROBLEM_ID.

Incident Details (page 4)

SELECT i.SEVERITY,i.INCIDENT_NUM, t.TARGET_NAME,t.HOST_NAME, i.PRIORITY,i.CREATION_DATE, i.LAST_UPDATED_DATE FROM MGMT$INCIDENTS i, MGMT$TARGET t WHERE i.TARGET_GUID= t.TARGET_GUID AND i.INCIDENT_ID = :P4_INCIDENT_ID;

Development Demo

How About Some Extra?

• APEX supports HTML5 Charts, If we create dblinks to our target databases, we may even query ASH to draw nice performance charts.

How About Some Extra?

select null, TO_CHAR(sample_time, 'DD HH24:MI') st, avg(CPU) cpu, avg("User I/O") userio, avg(total-CPU-"User I/O"-"System I/O") others FROM (SELECT sample_time, sum(decode(session_state, 'ON CPU', 1, 0)) as CPU, sum(decode(wait_class, 'Scheduler', 1, 0)) as Scheduler, sum(decode(wait_class, 'User I/O', 1, 0)) as "User I/O", sum(decode(wait_class, 'System I/O', 1, 0)) as "System I/O", sum(decode(wait_class, 'Concurrency', 1, 0)) as Concurrency, sum(decode(wait_class, 'Application', 1, 0)) as Application, sum(decode(wait_class, 'Commit', 1, 0)) as Commit, sum(decode(wait_class, 'Configuration', 1, 0)) as Configuration, sum(decode(wait_class, 'Administrative', 1, 0)) as Administrative, sum(decode(wait_class, 'Network', 1, 0)) as Network, sum(decode(wait_class, 'Queueing', 1, 0)) as Queueing, sum(decode(wait_class, 'Other', 1, 0)) as Other, sum(1) total FROM gv$active_session_history@XXXXX WHERE sample_time > sysdate - (1 / 24) GROUP BY sample_time) group by TO_CHAR(sample_time, 'DD HH24:MI') order by 2;

How About Some Extra?

...with some dedication

Result:

What’s Next?

• Assigning Incidents to Users

• Reports (Be careful about licensing)

• Target Home Pages
