"No suitable driver found" error when connecting to different database with Pega rule base

zolly — Mon, 02 Jun 2014 18:15:00 GMT

Go into SMA -> Advanced -> Etier Runtime Environment

For Java class name (e.g.: com.microsoft.sqlserver.jdbc.SQLServerDriver) click on the Lookup Java Class button and confirm that the Java class is being found in the lib directory where you have put the jar file.

If the class is not found there please confirm that you restarted the app server after adding the jar file to the lib directory.

If the class is found in the lib directory like it should be please go back to the Database rule and try the test connection again and this time it should work.

Java��d��Oracle BLOB字段�C�Z��

zolly — Tue, 28 May 2013 05:33:00 GMT

导入导出Oracle BLOB字段不能使用SQL�Q�可以��用EXP或者EXPDP

EXP导出�C�Z��Q?br />

exp name/password@orcl file=E:/exp.dump log=E:/exp.log table=(tb_emp) query="""where UserName='FN'"""

EXPDP导出�C�Z��Q?br />Sample.bat

expdp name/password@orcl parfile=E:/expdp.par

expdp.par

DIRECTORY=dir_dump
DUMPFILE=backup.dump
LOGFILE=backup.log
TABLES=pr_data_admin
QUERY=pr_data_admin:"where UserName='FN'"

以上�Ҏ(gu��)��因�ؓ(f��)我电(sh��)脑上的Oracle版本对不上，��L��报错�Q�后来采用java的方法，本文主要介绍如何使用java��d��Oracle的BLOB字段�Q�达到复制�{�U�BLOB数据的目的。代码如下，加入ojdbc.jar�Q�复制代码可以直接运行：(x��)

��Z��Java Bouncy Castle的PGP加密解密�C�Z��

zolly — Fri, 24 May 2013 00:37:00 GMT

PGP即Pretty Good Privacy�Q�是一个基于RSA公钥&�U�钥及AES�{�非对称加密��法的加密��Y件系列，比较��h��代表性加密解密客��L(f��ng)��已被Symantec收购�Q�详见www.pgp.com�Q�在Symantec的网站上可以下蝲最新版客户端��Y件�?br />
本文讲的是��用Java��Z��Bouncy Castle包的PGP加密解密�C�Z��Q�按照以下步骤即可轻村֮�玎ͼ�(x��)

1. 客户端��Y�?br />�׃��Symantec的PGP客户端是收费软�g�Q�本文只需要��用其中的生成�U�钥和加密文件的功能�Q�用该��Y件有些浪费，所以我下蝲了Java 免费版的Portable PGP(http://sourceforge.net/projects/ppgp/)

2. 下蝲Bouncy Castle�?br />http://www.bouncycastle.org/latest_releases.html

bcprov-jdk15on-148.jar和bcpg-jdk15on-148.jar
Bouncy Castle支持大量的密码术��法�Q�其中包括OpenPGP�Q�引用很�q�泛�Q�Pega��是使用Bouncy Castle寚w��件和客户重要数据�q�行加密解密的�?br />它既可以安装成JDK扩展也可以放到特定java��目中��用�?br />
3. 在Oracle官网下蝲UnlimitedJCEPolicy

http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html
JDK默认Policy只能支持<=128位Key�Q�GPG的密钥从1024-2048�Q�所以必��L��展该Policy。具体安装方法参考文件中的ReadMe文�g�?/div>
4. �~�写代码

使用Portable PGP加密文�g后生成Public Key和Private Key。把试用Public Key加密的文�?Encrypted File.txt"和Private Key "Key.asc"一同放到项目文件夹中�?br />使用以下代码卛_��解密文�g�?拯��以下代码可以直接执行�Q�以下代码也是来自Bouncy Castle源代码包)

SQL删除某些字段重复的记�?只保留一�?

zolly — Thu, 02 May 2013 16:30:00 GMT

�?x��)员数据需要用到的是下面三个字�D?ID(自增),MemberName,MemberAddress.只要�?x��)员姓名与�?x��)员地址相同��p��为是重复记录,重复记录在删除时只保留ID最大的那个.SQL如下:

delete MemberInfo where ID not in (
select max(ID) from MemberInfo group by MemberName, MemberAddress)

not in的效率可能会(x��)低些,但因为是直接操作数据�?所以这�q�不重要.�q�个句子�q�是非常的简单有效的.
在真正的删除操作�?通常�?x��)先了解一下重复记录的情况.可以使用下面的句�?

SELECT COUNT(MemberName) AS TheCount, MemberName, MemberAddress
FROM MemberInfo
GROUP BY MemberName, MemberAddress
HAVING (COUNT(*) > 1)

Legacy System (or Legacy based Application) definition

zolly — Fri, 18 Dec 2009 08:26:00 GMT

1. Obsolete computer system that may still be in use because its data cannot be changed to newer or standard formats, or its application programs cannot be upgraded.
http://www.businessdictionary.com/definition/legacy-system.html

2. An information technology or other automated system that is technologically obsolete. It may be too expensive to update or replace, but it is still needed for the companyÂ’s operations and thus is kept operational even though a newer system is in use.
http://www.yourdictionary.com/finance/legacy-system

3. Legacy system from Wikipedia (http://en.wikipedia.org/wiki/Legacy_system)

http://topic.csdn.net/t/20050719/22/4155342.html

　　目前�Q�学术和工业界对遗留�pȝ��的定义没有统一的意见。Bennett�?995�q�对遗留�pȝ��作了如下的定义[1]�Q�遗留系�l�是我们不知道如何处理但�Ҏ(gu��)��们的�l�织又是臛_��重要的系�l�。Brodie和Stonebraker寚w��留系�l�的定义如下[2]�Q�遗留系�l�是指�Q何基本上不能�q�行修改和进化以满��新的变化了的业务需求的信息�pȝ��?

How to read and write Properties from pzPVStream column?

zolly — Mon, 01 Jun 2009 09:22:00 GMT

As we know, we can extract unexposed Property rules value from pzPVStream by using Obj-Open or Obj-List method in Activity steps, that is the only way we could operate binary data stored in pzPVStream.

I don't know how Obj-Open and Obj-List work, how to read pzPVStream to get the unexposed property. Is there any general way to get the binary data form database? If the pzPVStream image data is standardized data format, if not, how the PegaSystems to write and read it.

Can we read and write column value from pzPVStream by Java code directly out of PRPC? Any body who could provide any solution?

PDN said, Rules XML stream is stored in BLOB. Generally, BLOB column is not encoded if we don't check "Encrypt BLOB?".
Developer can read information by following: it is the way to read XML Stream from CLOB column.

Reader reader = ResultSet.getCharacterStream();

I try to use this method to write the stream into file, the content is always encode. I don't know what was wrong.

Business Intelligence Extract (BIX)

zolly — Wed, 27 May 2009 01:48:00 GMT

What is BIX?
BIX stands for Business Intelligence Extract , enables custormer to extract SmartBPM case data for the purpose of merging it with information from other enterprise systems in a centralized data warehouse. Organizations now have the ablility to quickly and easily select and extract all BPM data including work detail, assignment in various formats including SQL tables, comma-separated-values (CSV) files, and XML files. You can directly import these outputs into popular business intelligence applications for analysis and reporting. BIX can be added to any V5.1+system.

All data available for BIX. Extract concurrentlyfrom one or multiple PRPC.

BIX actually is a PRPC rules which havd functions that can extract Property rules data including Blob data from database into SQL statement, CSV and XML format file.
BIX as an general system rules be deployed on V5.5+ system.

That's the benchmark from Pega...and normally 500ms is the standard...any SQL/Activity , if the execution exceeds 500ms, it's not normal., we need to find out why...
