max_allowed_packet error in mysql

-


Caused by: java.sql.BatchUpdateException: Packet for query is too large (1434172 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.


The max_allowed_packet variable can be set globally by running a query.
However, if you do not change it in the my.ini file (as dragon112 suggested), the value will reset when the server restarts, even if you set it globally.

To change the setting for everyone until the server restarts:
SET GLOBAL max_allowed_packet=1073741824;

    I executed your suggestion (SET GLOBAL max_allowed_packet=8777000;) at MySQL Workbench, and it seemed to work. But now it hangs with no reason. Sigh.

Changing the Java VM Memory Limits in Pentaho BI

-
You can find docs biserver-ce\tomcat\webapps\pentaho\docs\ Changing the Java VM Memory Limits If you are running out of memory even though your server has a lot of RAM, you probably need to increase the resources allocated to the JRE instance that runs the Pentaho software you're trying to improve performance on. Adjusting the memory limit is an easy configuration change to make, but the instructions differ depending on the client tool or Web application server you're using. Refer only to the sections below that apply to your situation. Note: If you are running multiple Pentaho programs concurrently, the sum of their JVM maximum memory limits must not exceed the available RAM minus system overhead. Increasing Memory Limits on Microsoft Windows with a Graphical Installation By default, Tomcat has a relatively low memory allotment. This can cause out-of-memory errors in the BA Server fromtime to time. The below instructions will explain how to increase the mem

CAS with Pentaho Community Edition

-
In this week I integrate one of the most useful feature i.e. CAS (Single Sign on) with the help my collegue and online user community . So with my boss’ blessing, I decided to document what I had to do to make this work in the spirit of giving back to the community. Plus with the rising awareness of the benefits of BI even for small to medium corporations, I have no doubt that this information would be useful for someone somewhere. The need 1) CAS Server 2) Pentaho BI 3.x server (Community Edition) 3) Install certificate IMPLEMENTATION OF CAS CLIENT IN PENTAHO BI SERVER 1) \biserver-ce\pentaho-solutions\system\applicationContext-spring-security.xml make changes in applicationContext file for CAS Client. and add following jars in biserver-ce\tomcat\webapps\pentaho\WEB-INF\lib folder 1) spring-security-cas-client-2.0.5.RELEASE.jar 2) cas-client-core-3.1.10.jar After added jars and configuration in applicationContext file then install certificate step-1) download

utf8_general_ci VS utf8_unicode_ci what should we use?

-
These two collations are both for the UTF-8 character encoding. The differences are in how text is sorted and compared. Note: in new versions of MySQL use utf8mb4 , rather than utf8 , which is the same UTF-8 data format with same performance but previously only accepted the first 65,536 Unicode characters. Accuracy utf8mb4_unicode_ci is based on the Unicode standard for sorting and comparison, which sorts accurately in a very wide range of languages. utf8mb4_general_ci fails to implement all of the Unicode sorting rules, which will result in undesirable sorting in some situations, such as when using particular languages or characters. Performance utf8mb4_general_ci is faster at comparisons and sorting, because it takes a bunch of performance-related shortcuts. On modern servers, this performance boost will be all but negligible. It was devised in a time when servers had a tiny fraction of the CPU performance of today's computers. utf8mb4_unicode_c
