Speaking at E4!

I’ll be co-speaking with Randy Johnson (one of the authors of Expert Oracle Exadata) at E4 to share about the war stories and detail on a bunch of technical stuff on a Peoplesoft and BIEE consolidation project we had on one of our clients. See the abstract below:

Randy Johnson & Karl Arao

The effect of ASM redundancy/parity on read/write IOPS – SLOB test case! for Exadata and non-Exa environments

Last week I had a lengthy post at oracle-l that tackles Calibrate IO, Short Stroking, Stripe size, UEK kernel, and ASM redundancy effect on IOPS Exadata which you can read here
followed by interesting exchange of tweets with Kevin Closson here (see 06/21-22 tweets) which I was replying in between games at UnderwaterHockey US Nationals 2012 which we won the championship for the B division ;) I have my awesome photo with the medal here

This post will detail on the ASM redundancy/parity effect on IOPS… if… by changing the ASM redundancy (external, normal, and high) will it decrease the workload (more...)

Important R12 FV PO Commitment Accounting Attribute Assignment Updates identified in patch 13610367

Patch 13610367, released earlier this year, provided an update to the seeded Federal Purchasing AAD that is important for all R12.1 Federal PO Customers to understand, even if not using the seeded Federal SLA definitions.  The AAD change included updates to a couple of the key Accounting Attribute Assignments for the FV PO Commitment JLT. 

The changes were:

Accounting Attribute Assignment: Allocated to Distribution Type, changed to source: Allocated to Main Document Distribution Type
Accounting Attribute Assignment: Allocated to First Distribution Identifier, changed to source: Allocated to Main Document Distribution Identifier

The SLA configuration we’re using at my current gig is non-seeded and agency-unique but modeled (more...)

Poll Results and upcoming Oracle Event in Pune

Last month I have posted a poll on my blog and LinkedIn group Oracle Database Performance Tuning about suggestions for a topic for webcast. I am enraptured by the response I got and as you can see below majority of the people have voted in favor of presentation title “Database Capacity Planning how to start?”.

This is inline to my expectations. Last year I have delivered a presentation at AIOUG’s annual meet Sangam11 on the topic “Day Someone Say the word Capacity?”. It was about the basics and concepts related to Capacity planning in general with some specific (more...)

Java 7-Auto-Update Warning

It looks like, that all forms-applications run into a huge problem, starting next week, July 3rd 2012.

Oracle's Java 1.6-Updater will automatically update the JRE to 1.7 on all PC's, where auto-update is activated. And Java 1.7 is not certified with Forms 10g, Forms 11g or the E-Business-Suite (EBS-forms-components)

I try to find all relevant informations to that topic and blog them afterwards. So feel free to share this blog to all customers who may have this problem next week.

ORA-16792 configuration property value is inconsistent with database setting

As per the reference this error literally means:

Cause: The values of one or more configuration properties were inconsistent with database in-memory settings or server parameter file settings. This may happen by altering initialization parameters directly instead of altering property values using Data Guard broker.

Actions: Query property the InconsistentProperties on the database or check the Data Guard broker log to find which properties are set inconsistently. Reset these properties to make them consistent with the database settings. Alternatively, enable the database or the entire configuration to allow the configuration property settings to be propagated to to the (more...)

Exadata motherboard replacement


This photo story is about a motherboard replacement in an Exadata X2-2 database server (Sun Fire X4170 M2).

While setting up a half rack Exadata system, we discovered a problem with the motherboard in database server 4, so we got ourselves a new one. Even for an internal system, I had to log an SR, get our hardware team to review the diagnostics and have them confirm that a new motherboard is required. I had a full customer experience with me being both the customer and Support Engineer! Anyway, a replacement motherboard arrived the next day.

A small change in parallel insert with serial data access between 11.1 and 11.2

There is an interesting small change in parallel insert between 11.1 and 11.2 in queries with parallelized insert, but serialized data access. On a practice the simplest case where we can see this it is CTAS or parallel insert as select from remote table.
As an example I will use CTAS from remote table.

create table tbllocal parallel 2
    as select *
  from tblremote@dblink;

Note: even if remote part of this query (select from tblremote@dblink) will be parallelized, it will be run in parallel on remote side. Communication between remote and local servers will be performed in one (more...)
