Hi Surender,
My point is this:
The main purpose of the immloader is to load the imm as fast as possible (a
cluster restart is *the* archetypical
high-availability problem, if there is any). If the loading fails due to a
corrupt imm.xml file then the only priority
for the imm-loader is to clearly report that there _is_ a problem with the
file. It must not waste time/complexity/risk
on trying to do detailed diagnosis of exatly _what_ the error in the file is.
Currently the syslog printouts porvide the unambiguous reporting that make it
plain and simple to understand
when there is a problem with loading the imm.xml file.
The detailed analysis of what the problem is with an imm.xml file will have to
be done off-line using tools like immxml-validate.
So what you could do is to apply that tool to the corrupt file. If that tool
does not report clearly enough what the problem is,
then you could write a ticket on immxml-validate.

Subject: [tickets] [opensaf:tickets] #1145 IMM incorrect/irrelevant logging
during loading with modified/corrupt xml file
when you dump an object to xml, which doesn't have implementer set either to
class or object, then the implementer attribute is NOT dumped in to xml file.
I edited the xml file VERY carefully. NO syntax error nor any tags missing.
I didnot add ANOTHER implementer name. Just added the first one by editing the
dumped xml file.
Yes, if i revert the edited tags, the load works properly.
The multivalued error is not for the object information that i edited.Instead
it is for different object.
Attaching test.xml
To reproduce do
immcfg -f test.xml
immdump /tmp/imm.xml ( this xml does not have implementer attributed dumped )
Edit the dumped imm.xml and add the implementer attribute tags as said above.
Now load this new imm.xml
Attachment: test.xml (1.6 kB; text/xml)

Test:
Create a class and object

Edit the xml file to include the below tags under the object DN
<attr>
<name>SaImmAttrImplementerName</name>
<value>IMPL</value>
</attr>
i.e From :

<value>accessclass</value>
</attr>
<attr>

Now upload this modified xml file, with RepositoryInit pointing to load from
XML file.
Below is the ERR_INVALID_PARAM is observed and the reason being "it is not

All IMMNDs will restart
Sep 30 19:06:41 SC-1 osafimmd[11982]: NO Cluster failed to load => IMMDs will

In the modified xml file, nothing has been changed w.r.t object
logStreamSystemLowLimit. Yet, the irrelevant error.
