HBA_LoadLibrary() is unable to load library in Aries

[Kanagaraj M]

Hi,

In one of the application which uses the HBA_LoadLibrary() is aborted while executing with following error:

unable to load library /usr/lib/pa20_64/libhbaapihp.sl
unable to load library /usr/lib/hpux32/libhbaapihp.so
unable to load library /usr/lib/hpux64/libhbaapihp.so
unable to load library /usr/lib/pa20_64/libhbaapifcd.sl
unable to load library /usr/lib/hpux32/libhbaapifcd.so
unable to load library /usr/lib/hpux64/libhbaapifcd.so
Aries ERROR:[pid=16929] Got masked synchronous signal. Aborting...

Can anyone help to solve this issue?

Thanks

Something strange here. It seems to be loading both the PA and IPF versions of one shlib. Also 32 and 64 and .sl and .so.
Somebody is very persistent. :-)

suppose, Its the nature of the HBA_LoadLibrary(), a SNIA API. It will try to load all registered library in /etc/hba.conf file.

Any idea, on what scenario the error "Aries ERROR:[pid=xxxx] Got masked synchronous signal. Aborting..." occurs.

your help is very much value here !!

It could be the case if you have blocked signals and then have gotten that signal. This results in an infinite loop. Later HP-UX versions will now abort you.

Make sure you have the latest Aries and linker/dld patches. What OS version are you using?

Greetings,

HBA_LoadLibrary API should check the library being loaded against architecture, 32-bit/64-bit data model and load the matching one. The error is coming most likely due to failed library loading and reference to an invalid library handle by the application, HBA API library or the PA-RISC dld.

The error message from ARIES shows that application has blocked the signal (it could be in application code, HBA API library, dld). ARIES sees no point in continuing with synchronous exception if it cannot be delivered to application. Thus it kills the process with an error message.

Are you able to load the libraries from an Itanium native application? I wonder how will Itanium or PA-RISC dld can handle libraries of both architecture in same process.
