一、DESede加密(对应SunJCE不提供模式和填充的情况)
declare
result raw(2000);
l_mod number := dbms_crypto.ENCRYPT_3DES+dbms_crypto.CHAIN_ECB+dbms_crypto.PAD_PKCS5;
begin
result := dbms_crypto.Encrypt(src => utl_i18n.string_to_raw('wwww'),typ => l_mod,key => hextoraw('123456789012345678901234567890123456')
);
dbms_output.put_line(result);
end;
/
二,摘要
dbms_crypto.Hash(utl_i18n.string_to_raw('input'),dbms_crypto.MD5))

用了几天jira管理对它的权限模式有了初步理解:
project和permission schema多对一,从而形成了permission schema的重用
而permission schema本身则代表了group/user和pemission之前的映射关系
另外,jira还有一个Project Role的概念更增加了jira权限管理的灵活性
其实它实质上就是一个角色(RBAC中的R),可以和group/user多对多关联,
(当然也可和Permission通过schema进行关联)
使jira的权限配置更新灵活的同时,也增加了相当的复杂性

一,造libmysql.def文件
1, ${mysql_home}/include/libmySQL.def文件如果有直接用
2, 否则下载pexports工具,执行pexprots libmySQL.dll> libmySQL.def(libmySQL.dll在${mysql_home}/bin目录下一般会有)
二,转换成静态库
dlltool --input-def libmySQL.def --dllname libmySQL.dll --output-lib libmysql.a -k
三,配置Eclipse(静态库和动态库加法都是-L${DIR} -l${libname},但谁的优先级高呢?)
1, 加上库目录,如"${workspace_loc:/hello_mysql/libs}"
2, 加上libmysql.a的库名: mysql
3, 构建,报错: #ff0000 reference to `mysql_real_connect@32'之类的错
4, 修改def文件,将mysql_real_connect改成mysql_real_connect@32,其它错误同理,并重新生成静态库
5, 重新构建完成
四,示例程序(只须修改连接信息及表名)
#include <stdio.h>
/*下面这一行一定要加上*/
#include <my_global.h>
#include <mysql.h>
int main() {
MYSQL mysql;
MYSQL_RES *result;
MYSQL_ROW row;
int numrows, numcols, c;
mysql_init(&mysql);
if (!mysql_real_connect(&mysql, "localhost", "opencart", "opencart", "opencart", 0, NULL, 0)) {
fprintf(stderr,"Failed to connect to database: Error %d:%s\n", mysql_errno(&mysql), mysql_error(&mysql));
}
char query[] = "SELECT * FROM product";
if (mysql_query(&mysql, query))
{
fprintf(stderr,"Error executing query: Error %d: %s\n", mysql_errno(&mysql), mysql_error(&mysql));
}
result = mysql_use_result(&mysql);
if (!result) {
fprintf(stderr,"Error executing query: Error %d: %s\n", mysql_errno(&mysql), mysql_error(&mysql));
}
numcols = mysql_num_fields(result);
while (row = mysql_fetch_row(result)) {
for (c = 0; c < numcols; c++) {
printf("%s\t", row[c]);
}
printf("\n");
}
}

一、安装
1, 安装xampp
2, 安装zend studio[6]
二、配置调式
1,在http.conf中指定php.ini的位置
PhpIniDir "D:/xampp/php"
2, 在php.ini中的zend的部分指定以下内容(ZendDebugger.dll是从zend studio中搜出来的)
[Zend]
zend_extension_ts = "D:\xampp\php\zendOptimizer\lib\ZendDebugger_5.2.12.dll"
;下面部分可选
zend_debugger.allow_hosts=127.0.0.1/32,127.0.0.1/24
zend_debugger.expose_remotely=allowed_hosts

放在/usr/local/bin下,挺好用
#!/bin/sh
# this script converts an rpm into a plain tarball
mkdir $$.cpio
rpm2cpio $@ > $$.cpio/foo
cd $$.cpio
cpio -i -m -d < foo
rm -f foo
find . -type d -perm 700 -exec chmod 755 {} \;
tar cvzf ../`basename $@ .rpm`.tar.gz .
cd ../
rm -rf $$.cpio

1,去http://rpm.pbone.net/下载下列rpm包并安装
libnasl-2.2.9-1.fc5.i386.rpm
nessus-core-2.2.9-1.fc5.i386.rpm
nessus-core-debuginfo-2.2.9-1.fc5.i386.rpm(可选)
nessus-libraries-2.2.9-1.fc5.i386.rpm
nessus-server-2.2.9-1.fc5.i386.rpm
nessus-gui-2.2.9-1.fc5.i386.rpm
2, 找个能用的邮箱去http://www.nessus.org/plugins/index.php?view=register注册一下
3, 按邮件中的方式运行nessus-fetch --register ****
4, 运行nessus-adduser增加一个没有rule的用户
5, 运行nessus-mkcert造个证书
6, 运行nessus-fetch --check检查一下状态
7, 如果前面没啥问题,运行service nessusd start
如果这一步除了成功没啥别的输出就ok啦

限制本机的对外访问(例如不让测试环境访问生产库):
iptables -t filter -A OUTPUT -d 192.168.2.2 -p tcp --dport 1521 -j REJECT
#端口转发到另一台机器上
-A PREROUTING -d $ip1 -i eth0 -p tcp -m tcp --dport $port1 -j DNAT --to-destination $ip2:$port2
-A POSTROUTING -d $ip2 -p tcp -m tcp --dport $port2 -j SNAT --to-source $ip1
#本机端口相互映射
-A PREROUTING -p tcp --dport $port1 -j REDIRECT --to-port $port2

pre-commit.tmpl,然后更名pre-commit并加上执行权限:
#!/bin/sh
REPOS="$1"
TXN="$2"
RES="OK"
# Make sure that the log message contains some text.
SVNLOOK=/app/subversion/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | egrep "[^[:space:]]+" >/dev/null || unset RES
if [ "$RES" != "OK" ]
then
echo "You must input some comments for you commit" >&2
exit 1
fi
# All checks passed, so allow the commit.
exit 0

一,将pem格式的key文件导入keystore
摘抄备用:http://www.agentbob.info/agentbob/79-AB.html
说明: 经试验证书的pem文件可能通过keytool直接导入keystore中的
Apache Tomcat and many other Java applications expect to retrieve SSL/TLS
certificates from a Java Key Store (JKS). Jave Virtual Machines usually come
with
keytool
to help you create a new key store.
Keytool helps you to:
- create a new JKS with a new private key
- generate a Certificate Signung Request (CSR) for the private key in this JKS
- import a certificate that you received for this CSR into your JKS
Keytool does not let you import an existing private key for
which you already have a certificate. So you need to do this yourself, here's
how:
Let's assume you have a private key (key.pem) and a
certificate (cert.pem), both in PEM format as the file names
suggest.
PEM format is 'kind-of-human-readable' and looks like e.g.
-----BEGIN CERTIFICATE-----
Ulv6GtdFbjzLeqlkelqwewlq822OrEPdH+zxKUkKGX/eN
.
. (snip)
.
9801asds3BCfu52dm7JHzPAOqWKaEwIgymlk=
----END CERTIFICATE-----
Convert both, the key and the certificate into DER format using
openssl :
openssl pkcs8 -topk8 -nocrypt -in key.pem -inform PEM -out key.der -outform DER
openssl x509 -in cert.pem -inform PEM -out cert.der -outform DER
Now comes the tricky bit, you need something to import these files into the
JKS. ImportKey will do this for you, get the
ImportKey.java (text/x-java-source, 6.6 kB, info) source or the compiled (Java 1.5 !)
ImportKey.class (application/octet-stream, 3.3 kB, info) and run it like
user@host:~$ java ImportKey key.der cert.der
Using keystore-file : /home/user/keystore.ImportKey
One certificate, no chain.
Key and certificate stored.
Alias:importkey Password:importkey
Now we have a proper JKS containing our private key and certificate in a file
called keystore.ImportKey, using 'importkey' as alias and also as password. For
any further changes, like changing the password we can use keytool.
二、将私钥导出成pem文件(默认keytool是不能导出私钥的)
import sun.misc.BASE64Encoder;
import java.security.cert.Certificate;
import java.security.*;
import java.io.File;
import java.io.FileInputStream;
class ExportPriv {
public static void main(String args[]) throws Exception{
ExportPriv myep = new ExportPriv();
myep.doit();
}
public void doit() throws Exception{
KeyStore ks = KeyStore.getInstance("JKS");
String fileName = "store.jks";
char[] passPhrase = "password".toCharArray();
BASE64Encoder myB64 = new BASE64Encoder();
File certificateFile = new File(fileName);
ks.load(new FileInputStream(certificateFile), passPhrase);
KeyPair kp = getPrivateKey(ks, "alias", passPhrase);
PrivateKey privKey = kp.getPrivate();
String b64 = myB64.encode(privKey.getEncoded());
System.out.println("-----BEGIN PRIVATE KEY-----");
System.out.println(b64);
System.out.println("-----END PRIVATE KEY-----");
}
// From http://javaalmanac.com/egs/java.security/GetKeyFromKs.html
public KeyPair getPrivateKey(KeyStore keystore, String alias, char[] password) {
try {
// Get private key
Key key = keystore.getKey(alias, password);
if (key instanceof PrivateKey) {
// Get certificate of public key
Certificate cert = keystore.getCertificate(alias);
// Get public key
PublicKey publicKey = cert.getPublicKey();
// Return a key pair
return new KeyPair(publicKey, (PrivateKey)key);
}
} catch (UnrecoverableKeyException e) {
} catch (NoSuchAlgorithmException e) {
} catch (KeyStoreException e) {
}
return null;
}
}

去年rails正火的时候,仿active record用hibernate实现了一个BasePo,当时用的是一个
静态sessionfactory注入的方式,感觉很不好,当明也没想到好的方案,后来发现有人通过
threadlocal实现了下面这个,可以看看:
1 public class Persistent implements Lifecycle, Validatable, Serializable {
2
3 protected Serializable _id;
4 protected int _version;
5
6 public Serializable getIdentifier() {
7 return _id;
8 }
9 public void setIdentifier(Serializable id) {
10 _id = id;
11 }
12 public int getVersion() {
13 return _version;
14 }
15 public void setVersion(int version) {
16 _version = version;
17 }
18
19 public Long persist() throws HibernateException, SQLException {
20 HibernateSession.currentSession().saveOrUpdate(this);
21 return _id;
22 }
23 public void delete() throws HibernateException, SQLException {
24 HibernateSession.currentSession().delete(this);
25 }
26 public void refresh() throws HibernateException, SQLException {
27 HibernateSession.currentSession().load(this, _id);
28 }
29 public void lock() throws HibernateException, SQLException {
30 HibernateSession.currentSession().lock(this, LockMode.UPGRADE);
31 }
32
33 public boolean onSave(Session s) throws CallbackException {
34 return NO_VETO;
35 }
36 public boolean onDelete(Session s) throws CallbackException {
37 return NO_VETO;
38 }
39 public boolean onUpdate(Session s) throws CallbackException {
40 return NO_VETO;
41 }
42 public void onLoad(Session s, Serializable id) {
43 _id = id;
44 }
45
46 public void validate() throws ValidationFailure {
47 }
48 }
原文:http://hibernate.bluemars.net/46.html?cmd=prntdoc
下面是hibernatesession的源码,应该考滤一下如何与spring事务结合的问题(还是加一个doInTransaction 的callback?)
1 import java.util.Collection;
2
3 import net.sf.hibernate.HibernateException;
4 import net.sf.hibernate.Session;
5 import net.sf.hibernate.Transaction;
6
7 import org.apache.commons.logging.Log;
8 import org.apache.commons.logging.LogFactory;
9
10 /**
11 * @author Ralph Schaer
12 * @version $Revision: 1.6 $ $Date: 2004/05/22 12:24:32 $
13 */
14 public class HibernateSession {
15
16 private static final Log LOG = LogFactory.getLog(HibernateSession.class);
17 public static final ThreadLocal SESSION = new ThreadLocal();
18
19 public static Session currentSession() throws HibernateException {
20
21 Session s = (Session) SESSION.get();
22 if (s == null) {
23 s = HibernateFactoryManager.getSessionFactory().openSession();
24 SESSION.set(s);
25 }
26 return s;
27 }
28
29 public static Session getSession() throws HibernateException {
30 return HibernateFactoryManager.getSessionFactory().openSession();
31 }
32
33 public static void closeSession() {
34 try {
35 Session s = (Session) SESSION.get();
36 SESSION.set(null);
37 if (s != null) {
38 s.close();
39 }
40
41 } catch (HibernateException e) {
42 LOG.error("HibernateSession: closeSession", e);
43 }
44
45 }
46
47 public static void rollback(Transaction tx) {
48 if (tx != null) {
49 try {
50 tx.rollback();
51 closeSession();
52 } catch (HibernateException he) {
53 LOG.error("HibernateSession: rollback", he);
54 }
55 }
56 }
57
58 //Utility methods
59 public static int collectionSize(Collection coll) throws HibernateException {
60 return ((Integer) currentSession().createFilter(coll, "select count(*)").iterate().next()).intValue();
61 }
62
63 }
还有一种考虑泛型的方式可以参考:

1,设置好WEB-INF/classes/xplanner-customer.properties中的数据连接,建mysql库[xplanner]
2, 运行会自动创建数据库表和sysadmin/admin用户
3, 中文乱码,先导出数据库[主要保存用户维护数据]
mysqldump --opt --database xplanner > xplanner.sql
4, 将sql中的create database语句改成default charset utf8;
5, souce xplanner.sql
6, 将server-config.wsdd[WEB-INF]下的附件上传位置改成合适目录
7, 重启xplanner即可

概念:
唯一的就是一个候选键(数据库理论基础)
所以要增加唯一性就是增加一个Alternate key
操作:
单击表模型,选中keys签,增加一个key,不选primary即可
信息来源sybooks online:

查找unique constraint找出和PDM相关的内容

网上说的比较多
不过一定要记住
看服务进程的log:
view /var/log/mysql.log
在我这里问题是:
/usr/libexec/mysqld: Can't create/write to file '/tmp/'
说明mysql用户无权使用/tmp目录,改一下目录权限就好了
chmow -R 777 /tmp

一,JIRA安装
1, 下载最新的JIRA(要注册才能得到测试liense)
2, 创建数据库用户[注意:jira用的utf8],create database jira default charset utf8; (mysql)
3, 按官网WIKI配置数据库,所有表会自动创建
二,SUBVERSION-PLUGIN
1, 下载插件
2, 拷完lib到指定位置即可(不要拷properties)
3, 在管理端增加仓库位置
三,svnwebclient
1, enscript不是语法加亮,只是加彩而已(而且大部分linux版本自带)

1, 下载http://www.allwiki.com/wiki/Mediawiki
2, 解压放到/var/www/html下,将config目录权限改为777
3, 给apache增加一个配置文件mediawiki.conf,内容如下:
<Directory "/var/www/html/mediawiki">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>
4,浏览器中输入:http://hostname/mediawiki/index.php
5,安装看是否缺php-mysql,如果缺到fc5的cd-rom中安装
6, 创建数据库
mysql -u root
create database mediawiki;
grant all on mediawiki.* to mediawiki@'localhost' identified by 'mediawiki';
6, 输入各项配置
7, mysql5创建表有问题,尚未解决,实在不行只能换个wiki看看了

1, 下载bugzilla
运行./checksetup.pl
2, 根据提示安装perl模块
位置:http://search.cpan.org/search?query=IO%3A%3AScalarArray&mode=all
下载后:
perl Makefile.pl
make
make test
make install
(过程如果有依整性错误,请安装相应模块)
3,配置mysql
mysql -u root
create database bugs
grant all on bugs.* to bugzilla@'localhost' identified by 'bugs'
4,配置vi ./localconfig设置数据库
5, 再次运行./checksetup.pl会创建数据库和设置bugzilla管理员(以mail作为登录名)
6, 将bugzilla目录拷到/www/html/下
7, 在/etc/httpd/conf.d/下增加bugzilla.conf内容如下:
AddHandler cgi-script .cgi .pl
<Directory "/var/www/html/bugzilla">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>
8,运行apachectl restart
9,访问:http://hostname/bugzilla/index.cgi
