\n

A partir da vers\u00e3o 4.5 Build 228, o E3 possui um recurso chamado Hands-Off Mode<\/b>. Esta ferramenta permite abrir os arquivos de projeto (.PRJ e .LIB) no modo hands-off<\/i>, possibilitando o sincronismo autom\u00e1tico entre dois servidores utilizando o DFS (Distributed File System).<\/p>\n

Algumas aplica\u00e7\u00f5es que utilizam Hot-Standby juntamente com auto-configura\u00e7\u00e3o (criar\/alterar\/salvar objetos em tempo de execu\u00e7\u00e3o) precisam propagar as altera\u00e7\u00f5es do PRJ para o micro standby. Para este e outros in\u00fameros casos, a solu\u00e7\u00e3o encontrada \u00e9 utilizar o DFS <\/b>(Distributed File System<\/b>), uma ferramenta do Windows Server que permite espelhar duas pastas em micros diferentes. Desta forma, ao salvar o PRJ em uma m\u00e1quina, o DFS se encarrega de copiar automaticamente o arquivo para o servidor standby.<\/p>\n

Para habilitar o Hands-Off Mode<\/b>, deve-se criar a chave abaixo (a chave HandsOffMode <\/i>\u00e9 um DWord):<\/p>\n

HKEY_LOCAL_MACHINE\\SOFTWARE[\\Wow6432Node]\\Elipse Software\\EFS\\HandsOffMode = 1<\/span><\/pre>\n
Quando este modo est\u00e1 ativo, os arquivos .PRJ e .LIB s\u00e3o carregados mas ficam liberados (o E3 faz uma c\u00f3pia dos arquivos para a pasta Temp<\/b>, e acessa os arquivos apenas nesta pasta, deixando os arquivos originais liberados). Isto permite que ferramentas de sincronismo de arquivos (DFS) possam copiar arquivos modificados no Hot para o Standby, e vice-versa.<\/p>\n
Com este modo habilitado, o procedimento do E3 para abrir arquivos .PRJ e .LIB \u00e9 o seguinte:<\/p>\n
    \n
  1. O arquivo PRJ ou LIB \u00e9 copiado para a pasta Temp <\/b>do usu\u00e1rio. O nome do arquivo gerado \u00e9 “EFS_{clsid}.tmp<\/span>“.<\/li>\n
  2. O arquivo tempor\u00e1rio \u00e9 aberto no modo direto (isto \u00e9, sem criar um snapshot) e mantido aberto pelo E3 enquanto estiver em uso.<\/li>\n<\/ol>\n
    Nos logs do E3, \u00e9 poss\u00edvel verificar que foram logados os m\u00f3dulos EFS. Por exemplo:<\/p>\n
    \n
    172013-11-20 15:52:27.22299603076EFSHandsOffMode: Temp file 'C:\\Windows\\TEMP\\EFS_{06632077-BAB3-4193-A689-110B63A29CF7}.tmp' was deleted14<\/span>\r\n\r\n182013-11-20 15:52:27.24499603076EFSHandsOffMode: Temp file 'C:\\Windows\\TEMP\\EFS_{49656153-0FAF-4656-87B1-B118D237EEA5}.tmp' created from 'C:\\Program Files (x86)\\Elipse Software\\Elipse E3\\Gallery\\SymbolFactory.prj'14<\/span><\/pre>\n<\/div>\n
    Os arquivos tempor\u00e1rios criados s\u00e3o apagados da pasta Temp <\/b>apenas em duas situa\u00e7\u00f5es:<\/p>\n
      \n
    1. Na primeira vez em que um arquivo \u00e9 aberto no Hands-Off Mode e um novo processo \u00e9 executado (antes que o arquivo seja aberto, ele tenta apagar os arquivos EFS_*.tmp que est\u00e3o na pasta Temp<\/b>); e<\/li>\n
    2. Sempre antes que um arquivo for aberto no Hands-Off Mode, desde que j\u00e1 tenham se passado 60 segundos desde a \u00faltima limpeza da pasta Temp<\/b>.<\/li>\n<\/ol>\n
      Desta forma, \u00e9 normal que alguns arquivos sobrem na pasta Temp <\/b>depois que um processo E3 for fechado. Normalmente, estes arquivos ser\u00e3o deletados na pr\u00f3xima vez que o E3 for executado.<\/p>\n
      Requisitos para utiliza\u00e7\u00e3o do Hands-Off Mode<\/b>:<\/p>\n
