Not able to register WCC with EEM

[Sunish Mittal]

Hello All,

I was not getting event drop down options in wcc quick view tab. I tried to add wcc user in event policy but still it was not showing. As per article given by Broadcom, i unregistered my WCC from EIAM URL and trying to register again.  
I am experiencing below error while registering WCC with EEM. I have restarted EEM service as well as wcc service but still getting error. Also wcc id and pw is correct. Please help here.

Note: Autosys scheduler, WCC and EEM are on same server.

[root@svcas0067 bin]# ./wcc_config.sh -u ejmcommander -p ejmcommander --displayeem
Logging in as 'ejmcommander' - FAILED
IAM not available.

Error in wcc log file:

Hi Sunish, 

That java.io.FileNotFoundException: ....(Too many open files) in log seems to suggest that the user owning the WCC process is hitting the max open files limit (ulimit nofile)
Try bumping it up and see if these errors go away. 

$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited

See if you are able to connect to the EEM server using the safex command line.

1. Create a XML file like so:
$ cat ~/safex_wcc.xml
<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<Safex>
<Attach label="WCC0004"/>
<Detach/>
</Safex>

$ /opt/CA/WorkloadCC/safex/safex -h <EEM_hostname> -u EiamAdmin -p <EiamAdmin_Password> -f ~/safex_wcc.xml
Setting Translation file:safex.tr
Setting back end to "<EEM_hostname>"

Setting locale to "en_us"
