Last updated on APRIL 26, 2021

Applies to:

Oracle WebLogic Server - Version 10.3.6 and later
Information in this document applies to any platform.

Symptoms

On Oracle Linux 6, Proxy plugin 11g works fine with WebLogic Server 10.3.6. However after configuring SSL per <Document 1384737.1 > and <Document 867883.1>, Apache can not be started with error below in error_log:

[Date&TimeStamp] [info] Shared memory session cache initialised
[Date&TimeStamp] [info] Init: Initializing (virtual) servers for SSL
[Date&TimeStamp] [info] mod_ssl/2.2.15 compiled against Server: Apache/2.2.15, Library: OpenSSL/1.0.1e-fips
[Date&TimeStamp] [notice] WebLogic Server Plugin version 1.1 <WLSPLUGINS_11.1.1.7.0_LINUX.X64_130212.0859>
[Date&TimeStamp] [info] mod_weblogic: init_mod: mpm doesn't support threads.
[Date&TimeStamp] [info] mod_weblogic: Testing Debug=ALL LogFile=/path/logs/wl_proxy.log TempDir=(null)
[Date&TimeStamp] [info] mod_weblogic: created global log context in child
[Date&TimeStamp] [crit] (20014)Internal error: WL SSL Init failed for server: (null) on 0
[Date&TimeStamp] [error] Error Initializing SSL: Return value is -2

 

And I see error below in wl_proxy.log:

[Date&TimeStamp] mod_weblogic(ssl): Cannot Load library: libwlssl.so
[Date&TimeStamp] mod_weblogic(ssl): Cannot Load library: libwlssl.so
[Date&TimeStamp] mod_weblogic(ssl): Cannot Load library: libwlssl.so
[Date&TimeStamp] mod_weblogic(ssl): Cannot Load library: libwlssl.so

 

strace results shows that the libwlssl.so is in the right place and Apache can successfully locate it and read it:

25983 16:54:23 open("/path/lib64/httpd/modules/libwlssl.so", O_RDONLY ) = 16
25983 16:54:23 read(16, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\240\31\0\0\0\0\0\0"..., 832) = 832
25983 16:54:23 fstat(16, {st_mode=S_IFREG|0755, st_size=26420, ...}) = 0
25983 16:54:23 mmap(NULL, 1067720, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 16, 0 ) = 0x7f9ac1b5c000
25983 16:54:23 mprotect(0x7f9ac1b61000, 1044480, PROT_NONE ) = 0
25983 16:54:23 mmap(0x7f9ac1c60000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 16, 0x4000 ) = 0x7f9ac1c60000
25983 16:54:23 close(16 ) = 0

 Installing libaio per <Document 1531922.1> does not solve the issue.
