How to add another LPAR with a new vlan to an existing SEA.
- Without downtime: Create one more virtual Ethernet with new vlan, then add this adapter to the current SEA and change the property with chdev command.
chdev -dev entX -attr virt_adapters=entY,entZ
(where entX is the SEA and entY is the adapter that was already part of the SEA and entZ is the new virtual adapter.
- With Downtime: Simple destroy and recreate the SEA with extra vlan tag port.
Advanced Analytics to Boost Business Intelligence (BI)
It has been almost a year that IBM acquired SPSS. Still many business users ask how to get more out of BI tools such as Cognos. Quoting IBM:
The combination of C8 BI and SPSS predictive analytics gives IBM customers more power and accuracy in answering the question of What should I be doing in the future? The combination of the powerful C8 BI analysis of current and historical data with the predictive analytic capability of the SPSS portfolio provides IBM customers with the predictive ‘brains’ for the next generation of decision making and business optimization.
The addition of the SPSS portfolio allows customers to leverage and extend their C8 BI investment by enhancing their analysis capabilities with predictive analytics. More specifically, the addition of SPSS predictive analytics helps analyze patterns found in historical and current transaction data as well as attitudinal survey data to predict potential future outcomes and proactively act upon that insight to drive better business outcomes.
Together with the market leading reporting and dashboarding capabilities of C8 BI, this predictive intelligence can be broadly distributed ensuring that decision makers across the organization gain those insights to drive business performance.
This may sound abstract, but in practical terms, with the ability to build sophisticated data models, SPSS enables extracting the essence of the heaps of data available today, and as a result dramatically reducing the time to present actionable information to decision makers. Still too abstract? By deploying models built with SPSS, decision makers can get answers to questions that otherwise might have required massive IT investment in more infrastructure, such as storage, memory and processing power.

If you need to go beyond classic SPAM and Virus filtering for your IBM Domino environment, we recommend you take a look at Lotus Protector for Mail Security. Starting at only $29.50 one time license fee per user, it is easy to see how the ROI over 1 year beats most commercially available solutions, and the ROI the 2nd year can mean as much as 75% savings over comparable solutions. A 90 day trial is available to test drive the product.
You reached the limit or your unhappy with the performance or features of your database server, and you want to move to DB2. The transition can be simple with respect to your code, as it may be just a matter of changing a few lines of code for the connection string, and setting the correct compatibility mode in DB2. But how do you move your data?
IBM has published a data migration toolkit, that has been updated to work best with DB2 9.7. Make sure you have service pack 2 installed, which is the latest service pack available as of this writing.
If you are migrating from MySQL or PostgreSQL, enable the ability to do limits and offsets in the where clause with:
echo Set compatibility to 01 or 0F
IBM has a comprehensive approach to encourage security by design. A free Red Book is available for developers: The IBM Redbook for Security in Development

If you are familiar with Linux and Solaris where the logs are typically in
/var/adm/messages, looking for the logs on an AIX system might be frustrating at first. The usual file locations are empty or non existent. By default the logs are actually in
You can change that behavior by configuring
There is also a system tools to view specific logs:
alog -o -t <log>
For example to view all the logs available, you can use:
Then you can request the boot logs for example with:
alog -o -t boot
There is a simple command that can be used to make sure that the basic configuration of sendmail is correct:
echo \$Z | sendmail -d0.1
The output of that command should look like:

When you look for a process in the
ps output, the command line of
grep often shows up:
ps auwwx | grep sshd
root 648 0.0 0.0 3732 1012 ? S Apr06 0:00 /usr/sbin/sshd
user 20807 0.0 0.0 4836 680 pts/0 S 04:31 0:00 grep /sshd
This can make writing scripts for automating sys admin tasks difficult.
There are many ways to get around this problem. Grep has for example exclusion pattern option. However, there is a simple way when you use a shell that allows character regular expressions: using a simple expression that will not alter what you are searching for, yet prevent the command line itself from being matched. For example:
$ ps auwwx | grep /ssh[d]
root 648 0.0 0.0 3732 1012 ? S Apr06 0:00 /usr/sbin/sshd
Notice the grep command line doesn’t appear any more in the results.
You heard that SPSS can dramatically improve the efficiency of your data warehouse, reporting and data analytics processes. But how to get started?
Here are some links that will get you pretty far:
Since Windows Vista (that includes Windows 7), the place where programs store some of their information has changed. This makes finding the DB2 log files (equivalent of
db2diag.log) more difficult.
The log files have moved under the directory tree node
C:/Program Data/IBM/DB2/DB2COPY1/DB2. Under that directory there is a
log and an
events directory. This being Windows, the
events directory has the logs that on Linux/Unix are the equivalent of the
Windows Vista: Where is db2diag.log location?
