【Python / Ansible】 Ansible実行時、pycryptoのバージョンによりAttributeError
pycrypto(バージョン2.4以上)をインストールしている状態でansibleを実行すると、下記エラーが出るみたい？
pycrypto 2.3 をインストールすると正常に動作することを確認し、2.4、2.6.1(執筆時点での最新バージョン)インストール状態で動作確認した際はエラーとなりました。

追記(2015/04/30)
下記issue内にてエラー発生源の処理をコメントアウトする方法で対応した方もいましたので、そちらも紹介致します。
※紹介先サイトで対応した方も、正しい対応かはわからないけど...と言っていますので、こちらの対応が正かどうかは自信ありません。申し訳ございません
下記対応を入れた状態で、pycryptoのバージョンを2.4以上のものにアップデートして、正常に動作することを確認しました。
/usr/lib64/python2.6/site-packages/Crypto/Util/number.pyの下記処理(56～57行目)をコメントアウト

【vagrant】 Vagrant up時に ゲストOSのGuest Additions moduleビルドに失敗する
vagrant up時にプラグイン「vagrant-vbguest」をインストールしておくと、ゲストOSのVirtualBox Guest Additionsのバージョンチェック＆更新をしてくれる。
しかし、利用しているBoxイメージによってはkernelのversionが古いためにGuest Additions moduleのビルドに失敗する様子。
そのため、この状態では共有ディレクトリのマウントに失敗します。
対応方法をいろんな人が同じような記事を書いていますが自分もメモ。

The headers for the current running kernel were not found. If the following
module compilation fails then this could be the reason.
The missing package can be probably installed with
yum install kernel-devel-2.6.32-431.3.1.el6.x86_64

An error occurred during installation of VirtualBox Guest Additions 4.3.26. Some functionality may not work as intended.
In most cases it is OK that the "Window System drivers" installation failed.

Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:
mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant
The error output from the last command was:
/sbin/mount.vboxsf: mounting failed with the error: No such device

【vmware】 1つの仮想マシンに設定できる仮想NIC数上限(vSphere5.5)
vSphere ESXi上の一つの仮想マシンに仮想NICはいくつ追加できるのか調べてみました。
環境
vSphere 5.5
上限
仮想NICの上限値は 10
公式ドキュメントを見ると 10^6と表記されていてると見間違えてしまったが、実際は注釈でしたので、最大10個まで仮想NICは設定できるみたいです。 http://www.vmware.com/files/jp/pdf/vsphere-55-configuration-maximums.pdf
【Oracle】 DBインスタンス起動時に予めバッファーキャッシュに指定テーブルの表データを格納するトリガー
概要
DBインスタンスを起動する際に、事前に指定テーブルの表データをバッファキャッシュに格納するためのトリガー設定
ヒント句を用いて対象テーブルをフルスキャンかけてキャッシュに読み込ませる。
トリガー
create or replace trigger "<schema>"."<trigger_name>" after startup on database declare cnt number(10); begin select /*+ full(<schema>.<table>) */ count(*) into cnt from <schema>.<table> end; /

【Oracle】 RACバックグラウンドプロセス(11gR2)
RAC関連のバックグラウンドプロセス
- RAC Background Processes
- Lock Monitor Processes (LMON)
- Lock Monitor Services (LMS)
- Lock Monitor Daemon Process ( LMD)
- LCKn ( Lock Process)
- DIAG (Diagnostic Daemon)
OracleRAC関連の隠しパラメータによく_lm_hoge_fugaみたいに、lmから始まるものが多くて、lmって何の略だろうと思っていたが、Lock Monitorの略ってことでいいのかな？

【Oracle】 カーディナリティ・フィードバック(Cardinality Feedback)
同じSQLを実行しても同じ実行計画が選択されない場合がある。 そのような状況が発生している場合、11gR2より実装されたカーディナリティ・フィードバック機能(Cardinality Feedback)が影響している可能性がある。
カーディナリティ・フィードバック(Cardinality Feedback)
- 実行計画を生成するCBOのインプット情報に実データのカーディナリティを加えることによって、より最適な実行計画を生成する機能
- ハードパース時、統計情報と実データのカーディナリティにかい離がある場合、そのカーディナリティを記録し、その後実行される同一SQLの実行計画は、実データを加味して最適になるように変更される可能性がある

設定方法
※ 隠しパラメータは通常、「サポートセンターの指示なしでは設定すべきでない」パラメータですのでご注意ください
隠しパラメータ _optimizer_use_feedback をTRUEに設定する(デフォルト値はTRUE)
