I’m installing ODI agent on our database server using OUI. I selected the “Server” option at install time to get the Agent only, but looking in oracledi/bin odiparams.sh is missing: $ls -l *.sh -rwxrwxrwx 1 odiadm dba 685 Nov 21 15:58 agent.sh -rwxrwxrwx 1 odiadm dba 908 Nov 21 15:58 agentscheduler.sh -rwxrwxrwx 1 odiadm dba 707 Nov 21 15:58 agentstop.sh -rwxrwxrwx 1 odiadm dba 941 Nov 21 15:58 agentweb.sh -rwxrwxrwx 1 odiadm dba 724 Nov 21 15:58 jython.

If you work with a file in Windows and Unix at some point you might end up with windows line feed characters in your Unix file. It’ll look like this: one line of text ^M next line ^M and next line with more ^M To remove the ^M character, load the file into vi on unix and enter as a line command the following: :1,$s/^M// but instead of typing ^M do Ctrl-V Ctrl-M to get the charaters

We’re getting problems with an instance of Informatica / out-of-the-box OBIA on a new set of servers.

The Oracle BI Publisher Enterprise Cluster Deployment doc which I just found through Metalink highlighted a couple of points: - Report repository should be shared - The scheduler should be configured for a cluster Report Repository Through Admin>System Maintenance>Report Repository I changed the path from the default, /xmlp/XMLP to a NFS mount data/shared/xmlp and restarted the xmlpserver application in OAS. On coming back up Publisher complained because all its config files (in xmlp/Admin), had disappeared.

I’m learning about a lot of the Oracle BI stack through reading manuals and trial-and-error. One thing I’ve realised is that Metalink holds a whole heap of useful information. For example, simply searching on “publisher cluster” throws up these two very pertinent docs: OBIEE Clustered Installation with BI Publisher (Doc ID 744515.1) BI Publisher does not accept cluster jdbc connection strings (Doc ID 559795.1) The first one is a publically available PDF, the second one is the answer to the problem I spent more time than I needed to scratching my head over yesterday.

In setting the scheduler in Publisher I discovered a useful difference in jdbc drivers. Our repository is on Oracle 11g. According to the manual oracle.jdbc.driver.OracleDriver should be used, but previous installations have used oracle.bi.jdbc.AnaJdbcDriver so I tried this too. In experimenting with both I found you get more useful feedback from the second one. Here’s the same problem reported by both drivers: · Exception [TOPLINK-4002] (Oracle TopLink - 11g Release 1 (11.

Following my previous work on configuring Publisher, I wanted to note down where the changes were written to. The -mname syntax of the unix find command comes in handy here: find /app/oracle/product/obiee -mtime -1 Shows me all files under the specified path which were modified in the last 1 day and helpfully throws up: /app/oracle/product/obiee/xmlp/XMLP/Admin/DataSource/datasources.xml

I’m setting up a clustered OBIEE 10.1.3.4 production environment. There are four servers; two BI Server + Cluster Controller + Scheduler and two OAS + Presentation Services + Publisher. Clustering of BI is configured, now I’m setting up the other bits. Today is Publisher. On publisher instance A connections to the BI Servers directly work fine: jdbc:oraclebi://serverA.fqdn.company.net:9703/ jdbc:oraclebi://serverB.fqdn.company.net:9703/ both work individually as Connection Strings (with database driver class of oracle.bi.jdbc.AnaJdbcDriver) - verified with “Test Connection” button.

As I explore the current world of data & analytics engineering, one of the things I’m trying to grok is the idea of a Metric Layer (described by Drew Banin in this keynote: https://www.youtube.com/watch?v=MdSMSbQxnO0 and Benn Stancil here https://benn.substack.com/p/metrics-layer). It strikes me as conceptually similar to what #OBIEE did in its logical layer with measures. Admittedly it was almost always exposed through the tool’s front end itself, but there was an ODBC and JDBC (https://rmoff.
