bob*_*bob 6 linux db2 odbc ibm-midrange
我试图在Linux Centos服务器上访问php作为/ 400(iSeries)db2数据库.
我尽可能地使用这个IBM指南,(尽管我们无法使GUI配置实用程序正常工作.)
http://www-03.ibm.com/systems/i/soft...ide/index.html
我下载并成功安装了iSeriesAccess驱动程序和先决条件.
rpm -i iSeriesAccess-5.4.0-1.6.i386.rpm
我已配置这些文件来定义驱动程序/ DNS:
/etc/odbc.ini和/etc/odbcinst.ini
[iSeries Access ODBC Driver] Description = iSeries Access for Linux ODBC Driver Driver = /opt/ibm/iSeriesAccess/lib/libcwbodbc.so Setup = /opt/ibm/iSeriesAccess/lib/libcwbodbcs.so Driver64 = /opt/ibm/iSeriesAccess/lib64/libcwbodbc.so Setup64 = /opt/ibm/iSeriesAccess/lib64/libcwbodbcs.so Threading = 2 DontDLClose = 1 UsageCount = 1
文件/etc/odbc.ini为空,所以我添加了这个配置:
[AS400] Description = iSeries Access ODBC Driver Driver = iSeries Access ODBC Driver System = 172.999.999.999 (from netstat option 1) UserID = my_user Password = my_pass Naming = 0 DefaultLibraries = QGPL Database = ConnectionType = 0 CommitMode = 2 ExtendedDynamic = 1 DefaultPkgLibrary = QGPL DefaultPackage = A/DEFAULT(IBM),2,0,1,0,512 AllowDataCompression = 1 LibraryView = 0 AllowUnsupportedChar = 0 ForceTranslation = 0 Trace = 1 DSN = AS400
我认为这些都有效,因为我可以跑
isql -v AS400
并且我成功连接到db2数据库可以从Linux框执行查询.
但是我无法在Linux机器上的PHP中获得make和ODBC连接.还有另一种方法可以从php测试DSN吗？或获取更详细的错误信息？
$server="172.999.999.999";
// tried with both system name and "AS400", the dsn name
$user="my_user";
$pass="my_pass";
$conn=odbc_connect($server,$user,$pass);
if ($conn == false) {
echo "Not able to connect to database...
";
}
结果:
**Not able to connect to database...**
phpinfo()显示php是使用unixODBC编译的,启用了unixODBC.
任何帮助表示赞赏!
尝试仔细检查odbcinst.ini和odbc.ini配置文件.您是否在odbc.ini中设置了正确的数据库名称/默认库？我按照这些说明成功了:
http://werk.feub.net/2010/11/ingredients-php-db2-and-unixodbc/
一个区别是我找到了一个包含libXm.so.3的openmotif版本.
http://rpm.pbone.net/index.php3/stat/3/limit/2/srodzaj/1/dl/40/search/libXm.so.3/field[]/1/field[]/2
安装php-odbc后重启apache.
/etc/odbc.ini
[ISERIES]
Description = iSeries Access ODBC Driver DSN for iSeries
Driver = iSeries Access ODBC Driver
System = 192.168.1.1
UserID = MYUSER
Password = MYPASSWORD
Naming = 0
DefaultLibraries = QGPL
Database =
ConnectionType = 0
CommitMode = 2
ExtendedDynamic = 0
DefaultPkgLibrary = QGPL
DefaultPackage = A/DEFAULT(IBM),2,0,1,0,512
AllowDataCompression = 1
LibraryView = 0
AllowUnsupportedChar = 0
ForceTranslation = 0
Trace = 0
示例PHP:
<?php
if (!$db = odbc_connect ( "ISERIES", "MYUSER", "MYPASSWORD") )
echo 'error!';
$result = odbc_exec($db, "SELECT * FROM MYUSER.TABLENAME");
while (odbc_fetch_row($result)) {
echo odbc_result($result, "ID")."\n";
}
odbc_close($db)
?>
我有类似的问题.我终于找到了这篇帖子:https://adminramblings.wordpress.com/2015/02/27/odbc-from-linux-to-iseries-as400-for-php/帮助我安装了正确的驱动程序,配置它们并连接到数据库.我将在此处包含以下信息以防万一:
从Linux到ODBC的ODBC(AS400)用于php
发布时间:2015年2月27日| 作者:Stephen Dart | 提起下:未分类|发表评论
使用linux(Ubuntu)框连接到IBM iSeries(AS400)以使用php查询和报告
IBM ODBC驱动程序(需要登录)http://www-03.ibm.com/systems/power/software/i/access/linux/guide.html
使用php和odbc模块安装apache.
sudo apt-get install libapache2-mod-php5 apache2 php5-odbc
安装unixodbc
sudo apt-get install unixodbc
将下载的iseries odbc驱动程序复制到服务器并安装
sudo dpkg -i ibm-iaccess-1.1.0.2-1.0.amd64.deb
将库符号链接到/ usr/lib文件夹以供系统使用
sudo ln -s /opt/ibm/iSeriesAccess/lib64/libcwb* /usr/lib
我们现在可以使用驱动程序创建odbc设置.找到SYSTEM odbcinst.ini和odbc.ini文件的位置:
odbcinst -j
unixODBC 2.2.14
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
编辑文件,odbcinst.ini文件应该已经在其中安装了IBM iseries驱动程序作为驱动程序安装的一部分,但默认文件缺少我发现导致问题的标题[ODBC驱动程序],因此可以添加到最佳.
/etc/odbcinst.ini
[ODBC Drivers]
IBM i Access ODBC Driver
Description = IBM i Access for Linux ODBC Driver
Driver = /opt/ibm/iSeriesAccess/lib/libcwbodbc.so
Setup = /opt/ibm/iSeriesAccess/lib/libcwbodbcs.so
Driver64 = /opt/ibm/iSeriesAccess/lib64/libcwbodbc.so
Setup64 = /opt/ibm/iSeriesAccess/lib64/libcwbodbcs.so
Threading = 0
DontDLClose = 1
UsageCount = 2
[IBM i Access ODBC Driver 64-bit]
Description = IBM i Access for Linux 64-bit ODBC Driver
Driver = /opt/ibm/iSeriesAccess/lib64/libcwbodbc.so
Setup = /opt/ibm/iSeriesAccess/lib64/libcwbodbcs.so
Threading = 0
DontDLClose = 1
UsageCount = 2
现在为您的特定系统创建odbc.ini,这对创建[ODBC数据源]和[DSN]很重要
示例odbc.ini
[ODBC Data Sources]
DEV = DEV
[DEV]
Description = iSeries Access ODBC Driver
Driver = IBM i Access ODBC Driver
System = FQDN or IP
UserID = USER
Password = PASSWORD
Naming = 1
DefaultLibraries = QGPL
Database =
ConnectionType = 2
CommitMode = 2
ExtendedDynamic = 1
DefaultPkgLibrary =
DefaultPackage = A/DEFAULT(IBM),2,0,1,0,512
AllowDataCompression = 1
LibraryView = 0
AllowUnsupportedChar = 1
ForceTranslation = 1
Trace = 0
odbc中括号内的名称是DSN,在这种情况下,odbc.in中的[DEV]驱动程序需要匹配odbcinst.ini中指定的名称
System是fqdn或IP中的网络名称.
用户ID和密码是登录iseries所必需的.
DefaultLibraries,Database和DefaultPkgLibrary可以根据需要指定或留空并在php中指定更高,我只使用DefaultLibraries.
使用命令行isql和DSN测试连接.
isql -v DEV
[unixODBC][Driver Manager]Can't open lib '/opt/ibm/iSeriesAccess/lib64/libcwbodbc.so': file not found
哦错误,这不好......但我找到了解决办法!
ispository驱动程序和libodbcinst的unixodbc库之间存在差异,这可能导致使用驱动程序时出现上述无意义错误.
该文件位于该位置,但实际库存在问题,并且错误消息不是很清楚.
要查看真正的错误,我们需要使用ldd来查看libcwdodbc.so的链接依赖项
ldd /opt/ibm/iSeriesAccess/lib64/libcwbodbc.so
linux-vdso.so.1 => (0x00007fff86dfe000)

在ubuntu软件包(当前版本为2.2.14p2-5ubuntu5)中有unixodbc的修复打包版本之前,我们可以将符号链接so.1到so.2.
sudo ln -s /usr/lib/x86_64-linux-gnu/libodbcinst.so.1 /usr/lib/x86_64-linux-gnu/libodbcinst.so.2
关于此的IBM文章:http: //www.ibm.com/developerworks/ibmi/library/i-ibmi-access-client-solutions-linux/
运行ldd现在可以看到所需的库.
ldd /opt/ibm/iSeriesAccess/lib64/libcwbodbc.so

现在我们可以重新运行isql和test.
isql -v DEV

SQL
Woot,连接!
好的,现在你有一个与你的iseries有效的ODBC连接,所以你可以通过DSN和你的应用程序使用它.
下一步是使用php链接到这个odbc.
Php页面使用select语句连接到DSN [DEV]并将结果放入表中:
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
</style>
</head>
<body>
<?php
try{
$as400conn = new PDO(‘odbc:DEV’);
// Note: The name is the same as what’s in our square brackets in ODBC.ini
$as400conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$library = “as400 library”;
$file = “as400 file”;
$i = 0;
$fields[$i++] = “file field 1?;
$fields[$i++] = “file field 2?;
$fields[$i++] = “file field 3?;
$AryLength = count($fields);
// Create SQL Have to include first field for comma separate outside of the while loop. field,field
$sql = “SELECT ” . $fields[0] ;
for($x = 1; $x < $AryLength; $x++) {
$sql = $sql . “,” . $fields[$x] ;
}
$sql = $sql.” FROM ” . $library . “/” . $file ;
echo $sql;
echo “<br>”;
$result = $as400conn->query($sql);
// Print Table Header //
echo “<table><tr>”;
for($x = 0; $x < $AryLength; $x++) {
echo “<th> $fields[$x] </th>”;
}
echo “</tr>”;
// Output Data of each row
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
echo “<tr> “;
for($x = 0; $x < $AryLength; $x++) {
echo “<td>” . $row[$fields[$x]] . “</td>”;
}
echo “</tr>”;
}
echo “</table>”;
$as400conn = null;
//end of try
}
catch (PDOException $e) {
echo $e->getMessage();
}
?>
</body>
</html>
我使用本教程安装了32位和64位版本的Ubuntu.如果要安装32位版本,只需调整一些文件夹名称即可.希望这有助于其他人.
