How to call SlaveOK on query in Mongoose? for example, I have this: SiteModel.find({}, function(err, docs) { .... } ); Should I do this??? SiteModel.slaveOK().find({}, function(err,docs) { ... } ); Here's the official example from the Mongoose.js website: Model .where('age').gte(25) .where('tags').in(['movie', 'music', 'art']) .select('name', 'age', 'tags') .skip(20) .limit(10) .asc('age') .slaveOk() .hint({ age: 1, name: 1 }) .run(callback); So I guess your example above would probably work, but do it like so: Model.find(conditions).slaveOk().run(callback); mongoose.Query.slaveOk has been

I have a Jenkins master (running on a small Linux box) and a Jenkins slave (running on a "correct" XP machine). I have configured both for all jibs to be run on the Windows XP slave. Unfortunatly, each time a build is run on that slave, the build fails due to the following error : ERROR: Ignore Problem expanding maven opts macros org.jenkinsci.plugins.tokenmacro.TokenMacro Found mavenVersion 3.0.3 from file jar:file:/E:/java-ext/apache-maven-3.0.3/lib/maven-core-3.0.3.jar!/META-INF/maven/org.apache.maven/maven-core/pom.properties Parsing POMs ERROR: Echec à la lecture des POMs hudson.util

I couldn't find an answer to my question. I have 2 mysql servers. Master server Slave server Now i want to add another Slave server but i have other website running on that server. Can i replicate just one database? Frank Fang Yes you can If you want to replicate just one database from master, you can set replicate-do-db in your /etc/my.cnf or set replicate-do-db as mysql argument, for example: replicate-do-db=db01 If you have multi databases to be replicated, /etc/my.cnf should be like this: replicate-do-db=db01 replicate-do-db=db02 If you just want slave to ignore some database, you can set

I'm trying to set one device for playback and another one for capture, my nano /etc/asound.conf has this: pcm.!default { type asym playback.pcm "plughw:1,1" capture.pcm "plughw:1,0" } ctl.!default { type hw card 0 } I can play sound perfectly, but I cannot record sound, my python code is throwing this errors: ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA

概述 Redis 支持简单且易用的主从复制（master-slave replication）功能， 该功能可以让从服务器(slave server)成为主服务器(master server)的精确复制品。 以下是关于 Redis 复制功能的几个重要方面： Redis 使用异步复制。 从 Redis 2.8 开始， 从服务器会以每秒一次的频率向主服务器报告复制流（replication stream）的处理进度。 一个主服务器可以有多个从服务器。 不仅主服务器可以有从服务器， 从服务器也可以有自己的从服务器， 多个从服务器之间可以构成一个图状结构。 复制功能不会阻塞主服务器： 即使有一个或多个从服务器正在进行初次同步， 主服务器也可以继续处理命令请求。 复制功能也不会阻塞从服务器： 只要在 redis.conf 文件中进行了相应的设置， 即使从服务器正在进行初次同步， 服务器也可以使用旧版本的数据集来处理命令查询。 不过， 在从服务器删除旧版本数据集并载入新版本数据集的那段时间内， 连接请求会被阻塞。 你还可以配置从服务器， 让它在与主服务器之间的连接断开时， 向客户端发送一个错误。 复制功能可以单纯地用于数据冗余（data redundancy）， 也可以通过让多个从服务器处理只读命令请求来提升扩展性（scalability）： 比如说， 繁重的 SORT

I need some help here, It's been a week I'm with this problem, can't figure out what's going on. I'm not able to clone a git repo from a slave node (Jenkins). I added the ssh key, host and slave (I've already tried generating a single key and one for each virtual and host)). On Jenkins: url:git@github.com: < repo> Credentials: Here I tried with username/password, username with ssh file, username with ssh key directly, and -none-. It doesn't seems like there is an authentication problem since I can clone the repo manually from console (both, slave and host). I can also connect with ssh -T git
