Can't locate object method "header_in" via package "Apache2::RequestRec" AdjustRemoteAddrAccordingToHeader.pm line 9

Ao migrar o Oracle Portal para versão 11G, o script AdjustRemoteAddrAccordingToHeader.pm começou a apresentar o seguinte erro:

Can't locate object method "header_in" via package "Apache2::RequestRec" at /u01/app/oracle/product/Middleware/asinst_1/config/OHS/ohs1/AdjustRemoteAddrAccordingToHeader.pm line 9

Para resolver este problema, basta acrescentar o seguinte:

use Apache2::compat;

AdjustRemoteAddrAccordingToHeader.pm:

package Apache::AdjustRemoteAddrAccordingToHeader;

use Apache2::compat;

sub handler
{
my $r = shift;
my $configuredValue = $r->dir_config ("UseIPFromHeader");
if ($configuredValue)
{
my $ip = $r->header_in($configuredValue);
if ($ip)
{
$r->connection->remote_ip($ip);
}
}
else
{
print STDERR "AdjustRemoteAddrAccordingToHeader: PerlSetVar UseIPFromHeader is not set, so I did not do anything\n";
}

# Adjust for Oracle HTTP Server and REMOTE_ADDR
# Remove this line if not necessary
$r->header_in("ClientIP", $r->connection->remote_ip());

return OK;
}

return 1;

Recommended Patches for Oracle Portal 11g (Doc ID 1443292.1)

13:09 No comments

Atualizar a versão do OPATCH 11.1.1x --> Patch:6880880

Aplicar o Patch:15844859 - MLR: MANDATORY PATCH FOR PORTAL 11G PATCHING V3 --> mesmo sendo da versão 11.1.1.4 ele é obrigatório para aplicar os patchs no 11.1.1.7.0

O Portal continua na versão 11.1.1.6, então mesmo no 11.1.1.7, deve-se aplicar os patchs abaixo:
Portal Repository Patch 15997732 - Generic Platform
Portal Repository Patch 13938784 - Generic Platform

Atualizar o WEBCACHE:

Oracle Web Cache 11.1.1.7.0
WebCache 11.1.1.7 Oct 2013 CPU Patch 17306880 or higher

Documentos interessantes:
Unable To Apply Oracle Portal 11g Patches Using OPatch Getting Too Many Arguments And OS Undefined Variable (Doc ID 1465506.1)

Error 1:
=======
opatch: line 386: [: too many arguments
- This is caused by using the double quotes " " in the opatch command. The readme incorrectly has these around the -pre section and they should not be there.

Error 2:
========

Please set your ORACLE_HOME to your 10.1.2 midtier installation home.
.....................................................................
OS: Undefined variable.

Command invocation returned Error... 'OS: Undefined variable.
', Return Code = 1

- This is caused by a few issues. Ensure you have the latest 11.1.0.0.0 OPatch version downloaded, and ensure you have the Mandatory Portal 11g Patching Patch which fixes issues with the patching tool itself.
Reference: Note 1443292.1 Recommended Patches for Oracle Portal 11g
- That patch applies to all Portal 11g versions.

OPatch found the word "warning" in the stderr of the make command.
Please look at this stderr. You can re-run this make command.
Stderr output:

/u01/app/oracle/product/11.2.0.3/db/precomp/lib/env_precomp.mk:2160: warning: ignoring old commands for target `pcscfg.cfg'

This is a warning only which opatch is reporting. The Patch has applied successfully and the warning output can be safely ignored.
