list-match problem with EMI2 WMS

Details GGUS #90240

Some CEs have enabled only a group or a role in their queues, not the entire VO:

GlueCEAccessControlBaseRule: VOMS:/gridit/ansys
GlueCEAccessControlBaseRule: VOMS:/gridit/ansys/Role=SoftwareManager

so, when your primary attribute is:

attribute : /gridit/ansys/Role=NULL/Capability=NULL

if you use an EMI-2 WMS, you cannot match those resources (instead you can if use EMI-1 WMS)

It seems that the problem is in the value of WmsRequirements contained the file /etc/glite-wms/glite_wms.conf: the filter set in that variable is different from the one used in the EMI-1 WMS. The developers are investigating on it

UPDATE Jan 31st: the fix will be released in EMI-3. However, the developers provided us a rpm, glite-wms-classad_plugin-3.4.99-0.sl5.x86_64.rpm, which we have installed on our EMI-2 WMS servers, and the issue has been fixed

LFC-Oracle problem

Details GGUS #90701

The error is occurring with EMI2 emi-lfc_oracle-1.8.5-1.el5 and Oracle 11:

#lfc-ls lfc-1-kit:/grid

send2nsd: NS002 - send error : client_establish_context: The server had a problem while authenticating our connection
lfc-1-kit:/grid: Could not secure the connection

Experts suspect it is due to the use of Oracle 11 client when the LFC code has been compiled against the Oracle 10 API. The LFC developers expect to provide rpms built against Oracle 11 shortly.

UPDATE Feb 5th: solved by applying the work around with:

add in /etc/sysconfig/lfcdaemon:
export LD_PRELOAD=/usr/lib64/libssl.so:/usr/lib64/libglobus_gssapi_gsi.so.4

the Oracle 11 build wasn't tested because the service is in production
