Mit dem Patchday Oktober 2012 ver\u00f6ffentlichte Microsoft ein Update (KB2661254), das die\u00a0Verwendung von RSA-Zertifikaten, die Schl\u00fcssel verwenden, die k\u00fcrzer als 1024 Bit sind, blockiert.
\n„Die Webseite kann nicht angezeigt werden“ oder „Internet Explorer cannot display the webpage“.
\n<\/p>\n

Dies kann zur folge haben, dass der Zugriff auf Grid Control 11g nicht mehr funktioniert, da dort standardm\u00e4\u00dfig ein selbst erstelltes bzw. signiertes RSA-Zertifikat mit 512 Bit hinterlegt ist.<\/p>\n

Um dort ein st\u00e4rker verschl\u00fcsseltes Zertifikat zu erstellen sind folgende Schritte n\u00f6tig:<\/p>\n

Stopp Grid Control OMS:<\/p>\n

%OMS_HOME%\\BIN> emctl stop oms\r\n\r\nOracle Enterprise Manager 11g Release 1 Grid Control\r\nCopyright (c) 1996, 2010 Oracle Corporation.  All rights reserved.\r\nStopping WebTier...\r\nWebTier Successfully Stopped\r\nStopping Oracle Management Server...\r\nOracle Management Server Successfully Stopped\r\nOracle Management Server is Down<\/pre>\n
Neues Zertifikat erstellen und hinterlegen:<\/p>\n
%OMS_HOME%\\BIN> emctl secure console -self_signed -key_strength 2048\r\n\r\nOracle Enterprise Manager 11g Release 1 Grid Control\r\nCopyright (c) 1996, 2010 Oracle Corporation.  All rights reserved.\r\nSecuring Console... Started.\r\nSecuring Console... Successful<\/pre>\n
Start OMS:<\/p>\n

Nachtrag zur DB Console (10.11.2012)
\nOracle hat einen Patch ver\u00f6ffentlicht, der die „Verschl\u00fcsselungsst\u00e4rke“ f\u00fcr die lokale DB Console der Version 11.1 bis 11.2 ver\u00e4nderbar macht. Nach Installation von Oracle Patch 14503114, m\u00fcssen nur noch folgende Schritte erledigt werden:<\/strong><\/p>\n
Stop DB Control:<\/p>\n
%ORACLE_HOME%\\BIN> emctl stop dbconsole\r\nSecure the DB Control console\r\n%ORACLE_HOME%\\BIN> emctl secure dbconsole -key_strength 1024 -reset\r\nStart the DB Control\r\n%ORACLE_HOME%\\BIN> emctl start dbconsole<\/pre>\n
Aber wie immer gilt RTFM der beiliegenden Patch-Readme.<\/p>\n
F\u00fcr DB Console 10.2 gibt es keine L\u00f6sung, au\u00dfer einen anderen Browser zu verwenden.
\n12.1 Cloud Control ist von diesem „Problem“ nicht betroffen.<\/p>\n
