log4j:ERROR Failed to read IPF startup parameters from ICCLConfiguration; error CAM-CRP-1057 Unable to generate the machine specific symmetric key.

Cause:
Cause:
------
Basic explanation: the encryption keys of the Java Virtual Machine of Cognos have become unusable.
Possible root cause: the ARC application was copied to another server.

Resolution:
Resolution:
-----------
(1)
Back up the existing Cognos configuration file /exlibris/crn/arc3_1/c8/configuration/cogstartup.xml by saving it under a different name, e.g. cogstartup.xml.sav.


(2)
Display the differences between the template file cogstartup.xml.tml and the existing file cogstartup.xml with the following command:

$ diff cogstartup.xml.tml cogstartup.xml


(3)
Open the file cogstartup.xml in a text editor.


(4)
Replace every line containing the string encrypted="true" with the corresponding XML element from the template file.

Example:
--------
$ diff cogstartup.xml.tml cogstartup.xml
[...]

< <crn:value xsi:type="cfg:credential">
< <credential>
< <username>C8AU@_AL_COPY</username>
< <password>C8AU@_AL_COPY</password>
< </credential>
< </crn:value>
---
> <crn:value xsi:type="cfg:credential" encrypted="true">MIHjBgkqhkiG9w0BBwaggdUwgdICAQAwgcwGCSqGSIb3DQEHATAKBggqhkiG9w0DBICBshxYPWHcWZMdJmWNjDlNsS0olrLaE2ZmALAlC95gN/svFd2tDLoLtPpS44WeyeWjoYfxw/3mPMV09slkk8tokv9iUxUIOMdsE2R0kKKC2xVpzwoy4x5BtVI8wTEnJJBRKyWI5rfpa/uZ5EDAj0SQwI7Ck2dX06LjRTMhg09ZUkasALn4CpRBp53lKjt0n6W1xoXJ/RoxwF7FiF+AQKUvZ4qo0aDrS2GkTpgrL3spZ7g0DfA=</crn:value>

(5)
Replace the placeholder @_AL_COPY with the value of the UNIX environment variable $ARC_COPY.

Example:
--------
$ echo $ARC_COPY
1

In this case the credentials in the file cogstartup.xml would look as follows:

<username>C8AU1</username>
<password>C8AU1</password>


(6)
Save the file cogstartup.xml and make a backup under the name cogstartup.xml.from_tml. That way you will not have to do all the manual editing in Step 4 again if you have made a mistake.


(7)
Start up the ARC processes with the following command:

$ cd $arce_root
$ ./arc_startup
