GAE sdk 1.1.9 problem with django helper(appengine_django)

2009-04-16 03:55:35   Category:Python   Comments:0   Reference:1   Tags:

The django helper could not find the app.yaml when I updated the gae sdk to 1.1.9 and djano version is 0.96. We need add the content into the app.yaml file to enable uploadding the app.yaml into the development envirment :

skip_files:
- ^(.*/)?app\.yml
- ^(.*/)?index\.yaml
- ^(.*/)?index\.yml
- ^(.*/)?#.*#
- ^(.*/)?.*~
- ^(.*/)?.*\.py[co]
- ^(.*/)?.*/RCS/.*
- ^(.*/)?\..*

Then django/core/management could not find the django.get_version function. We need modify the __init__.py in django directory:

VERSION = (0, 96.2, None)
def get_version():
    return Version

It works fine.

First day of oracle knowledge

2009-03-11 09:09:00   Category:Database   Comments:0   Reference:0   Tags:

1.Java, SQL and PL/SQL can be executed in the oracle server.
2.There are data file, redo log file and control file on the server.
3.1Multiple instances open one database in RAC(Real Application Cluster).
  3.2Streams is a tool of data synchronization between two databases or more.
  3.3 Data Guard is used to synchronize data between a primary database and a standby database.
4.An oracle instance consists of a block of SGA and some blocks of PGA. SGA contains buffer cache, log buffer(this is nearly real time, it must be written into disk when users commit), shared pool(include:library cache, data dictionary cache,PL/SQL area, result cache).

Install svn on turbolinux whith rpm package

2009-03-09 08:03:36   Category:管理   Comments:0   Reference:0   Tags: svn , turbolinux , rpm

  I installed the rpm version on my turbolinux and it work fine. Three files are needed:
    http://www.open.collab.net/nonav/downloads/subversion/gpg-key/RPM-GPG-KEY-csvn.asc
    http://downloads-guests.open.collab.net/files/documents/61/1375/CollabNetSubversion-client-1.5.5-1.i386.rpm
    http://downloads-guests.open.collab.net/files/documents/61/1376/CollabNetSubversion-server-1.5.5-1.i386.rpm
First, import the GPG key.
     sudo rpm --import /path/to/RPM-GPG-KEY-csvn.asc
Second, install the client.
     sudo rpm -ivh /path/to/client.rpm
Third, install the server.
     sudo rpm -ivh /path/to/server.rpm
Fourth, configure the path. add the following line to /etc/profile:
     PATH=/opt/CollabNet_Subversion/bin:$PATH
Fifth, configure the server and start the service.
    sudo Configure-CollabNet-Subversion
  The subversion server will be started automatically when the OS is started, because the collabnet_subversion is put in the /etc/rc.d/init.d/.

Modify the service port in Xampp

2009-03-05 07:52:41   Category:管理   Comments:0   Reference:1   Tags: xampp , port , bugfree

I　wanted to install a bugfree on a turbolinux. The Xampp was downloaded from http://www.apachefriends.org/en/xampp-linux.html and extracted into /opt/lampp/. I found that the service port is used by other application when I executed the command :/opt/lampp/lampp start. So I had to modify the ports to another valid ports.

First, I opened the /opt/lampp/lampp file(It checked the ports of apache) to modify the http port and ssl port.
Second, modified the http port in /opt/lampp/etc/http.conf("Listen 80" and "ServerName localhost").
Third, modified the ssl port in /opt/lampp/etc/extra/http-ssl.conf("Listen 443" and "ServerName www.example.com:443").
Then we can start our server: /opt/lampp/lampp start.

install svn server in my computer

2009-02-27 09:10:30   Category:管理   Comments:0   Reference:0   Tags: version , svn

I installed a svn server on my computer. It occured problem when I use different version server software and client software. For example we can not see the log messages. So we need get a svn server software and a appropriate version client software. I use svn server of version 1.5.5  and client of version 1.5.8. It work.
  The install of svn server is very simple on my winxp.
1. Get the svn server on http://www.open.collab.net/servlets/OCNDirector?id=CSVN1.5.5WINS.
2. Install it.
3. Create a repository:
    svnadmin create d:\svn\project1
3. Modify the \conf\svnserve.conf
    anon-access = none
    auth-access = write
    password-db = ../../passwd
    authz-db = ../../authz
4. Modify passwd
    harry = harryssecret
    sally = sallyssecret
5. Modify authz

    [/foo/bar]      #this path definition is used on all projects
    harry = rw
    &joe = r
    * =

    [project1:/baz/fuz]   #this path definition is used on project1
    @harry_and_sally = rw
    * = r
6. Start the server:
    svnserve -d -r d:\svn\
If you create some repositories in d:\svn\, they can be accessed.

project management software

Teamwork is a commercial production. It support to import project information from microsoft project file.
Achievo is a open source project software. It does not support microsoft project file. It can not show the tree structure of all tasks and gantt chart. I feel that it is not easy to make a plan.
XPlanner is a open source project management software developed in java. It does not support microsoft project file. It can not show the tree structure of all tasks and gantt chart. And the statistics function  is not enough for a project manager.
JIRA is a commercial production. But the workload statistics is based on the quantity of tasks. This is not very exact.
Projectivity is  open source project management and document management platform. It can show the tree structure of all tasks and gantt chart. This  is very useful, though it does not support microsoft project file. I am trying to use it.
