BI Web service security client - authentication operations for 11.1.1.6 and 11.1.1.7.x

This wlst/python script connects to bi security web service to authenticate a user specified in the "ObieeWebServiceClient.properties" file. In 11.1.1.7, this calls: getAuthenticatedUserWithLanguageAndProperties operation of the /bisecurity/service web service.

In 11.1.1.6, this calls authenticate operation of the /bimiddleware/security/service web service.

This returns as part of the xml response the user unique identifier (guid) and other permissions/roles for the user. This is useful when debugging an issue with OBIEE security.

The script has to be run with %ORACLE_HOME%\oracle_common\common\bin\wlst.cmd (sh)

Script is available there: https://blogs.oracle.com/pa/resource/ObieeWebServiceSecurityClient.zip

Following are the useful nqcmd command lines arguments:

a. In your environment set the "export SA_NQCMD_ADVANCED=yes"

b. Following is the description of the nqcmd command line arguments for BIServer (nqsserver) testing:

-d = Datasource.
-u = username.
-p = password.
-s = inputsqlsfile.
-o = outputfile. counters will be in outputfile_Counters.txt.
-td <secs> = timeduration in secs. nqcmd will run until <secs> elapses.
-qsel r = select queries random manner from inputsqlsfile.
-ds <secs> = dump statistics to outputfile_Counters.txt every <secs>.
-T = Timer is on. Otherwise you won’t get correct statistics.
-t <number> = generate users . if you give -t 50, 50 users will be there.
-q = turn off row output - mandatory flag for nqsserver load testing.
-n <number> = used for login test run for <number> iterations.
-w = thinktime (in seconds).

BI Check with WLST - SQL Datasources part 2

This second post continues with the BIEE security checks using WLST and python. This time, the following information is gathered about BISQLGroupProvider:

*  looking for SQLGroupProvider in the configured providers
*  retrieving the SQL queries
*  retrieving the JDBC source details
*  testing the connection pool, for each server that uses it (make sure your BI server is up and running)
*  testing the SQL queries directly against the database, with the test.user and test.group provided in the automation.properties file

OBIEE Web services with javascript

OBIEE web services provide a large set of operations on ibots, jobs, metadata, analysis, webcat...

http://docs.oracle.com/cd/E23943_01/bi.1111/e16364/methods.htm

A wsdl is provided for these services, and it is common to call them in a process running in Weblogic server (java custom application).  However, it is also possible to call them using javascript in a browser, or in a server with a javascript engine (Nodejs.org, or else).

EPM Infrastructure Tuning Guide v11.1.2.2 / 11.1.2.3

Applies To: This edition applies to only 11.1.2.2, 11.1.2.3.

One of the most challenging aspects of performance tuning is knowing where to begin. To maximize Oracle EPM System performance, all components need to be monitored, analyzed, and tuned. This guide describe the techniques used to monitor performance and the techniques for optimizing the performance of EPM components.

TOP TUNING RECOMMENDATIONS FOR EPM SYSTEM:

Performance tuning Oracle Hyperion EPM system is a complex and iterative process. To get you started, we have created a list of recommendations to help you optimize your Oracle Hyperion EPM system performance.

This chapter includes the following sections that provide a quick start for performance tuning Oracle EPM products. Note these performance tuning techniques are applicable to nearly all Oracle EPM products such as Financial PM Applications, Essbase, Reporting and Foundation services.

1. Tune Operating Systems parameters.
2. Tune Oracle WebLogic Server (WLS) parameters.
3. Tune 64bit Java Virtual Machines (JVM).
4. Tune 32bit Java Virtual Machines (JVM).
5. Tune HTTP Server parameters.
6. Tune HTTP Server Compression / Caching.
7. Tune Oracle Database Parameters.
8. Tune Reporting And Analysis Framework (RAF) Services.
9. Tune Oracle ADF parameters.

Essbase Best Practice: Essbase Security File Auto Backup Intervals

By default, Essbase will automatically backup the Essbase security file, Essbase.sec, every 300 seconds (5 minutes). Most customers find the frequency of the default backup interval overhead to be unnecessary given their security update needs. It is recommended to change the default setting before the “build” and “go-live” phases to have better Essbase.sec file backups proportionally spaced between backups and improve overhead.

Essbase 11.1.2.x - Changing Essbase ODL Logging Levels

ODL (Oracle Diagnostic Logging) information is recorded for both the Essbase agent and the Essbase application server. The level of the logging that is recorded can be amended if required.

These are the 2 ODL logs for Essbase:

  • EssbaseAgentODLLogger is for the Essbase agent. This writes to the ESSBASE_ODL.log in MIDDLEWARE_HOME/user_projects/epmsystem1/diagnostics/logs/Essbase/Essbase
  • DefSvrLogger is for the Essbase application server (ESSSVR). This writes to the <appname>_ODL.log in MIDDLEWARE_HOME/user_projects/epmsystem1/diagnostics/logs/Essbase/Essbase/app/<appname>

The level of logging for these Essbase ODL logs is controlled by the logging.xml file.
