tips and tricks

Table and cloumn comments can be queried from sys.systables and sys.syscolumns system views in Sybase IQ. Comments are stored in remarks column.

Hi All;

This is my Informatica 9.5.1 hot fix 2 preinstallation check list for IBM AIX.

1. Download Informatica software 9.5.1 HF1 for AIX from my.informatica.com via Global Customer Support.
2. Get the correct licence files from Global Customer support
3. Install Java version 6.
   http://www.ibm.com/developerworks/java/jdk/aix/service.html#java6
4. Install JDK 1.6.0 build pap6460sr13fp2-20130424_01(SR13 FP2) exactly.

5. There are some problems with AIX TAR, Install GNUTAR.
   http://www.gnu.org/software/tar/
6. Create User for informatica. (ex: infa, infauser, etluser... etc.)
7. Set u limit to 16.000 (or unlimited.)
   set ulimit -n to 16000
8. Create a database user for each Power Designer domain. (ex: INFADOM)
9. Create a database user for each Power Designer repository. (ex: INFAREP)
10. Verify that the database users have CONNECT, RESOURCE, and CREATE VIEW privileges.
11. For Oracle repositories Set the open_cursors parameter to 1000 or higher
12. If exist, open the following port range: 6000 to 6113 on firewall.
13. Do not believe curse of 13.
14. Reserve at least 1GB for Domain and repository database space (both users in the same tablespace)
15. Reserve at least 30GB file system space for installation on the server

Although Power Center shows this as possible, unfortunately you can not move binary or raw columns from source to target normally. You can try relational writer or external loader result is same. Binary/Raw column will be null.
It is impossible to convert this column as well.

Easiest way to do this is changing column definitions to varchar or nvarchar2 in Power Center. You do not have to change it on Database level at all. Data will start to move around as magic :)

find . -exec grep -l "search string" {} \;

In default to load data to Sybase IQ with Informatica external loader you have to transfer data to Sybase server.

With following code you can add follwing features to Informatica Sybase IQ External loader

• To be able to load data directly from Informatica Server
• Parallel External load, now instead of getting error, Informatica is waiting other transactions locking target table to finish. (Default unlimited, you can specify wait time if needed)
• Cleaning data, log and ctl files after successful load.

V1.1 updates

• External loader errors are logged file_name.err file

To configure your external loader simply point to this new file

Save following script to your Sybase IQ bin64 directory.
