I had to do something similar for a client at Harmony Heart Group. They were looking for the same type of access but didn't want it to interfere with their patient files. Great info.

Comment on installing TIBCO TRA 5.6 on a debian 64bit by Sol Mumey

Thanks! Great investigative work. Might be worth noting that you really DO need to make the file undeletable. On an ext4 filesystem I used

chattr +i /tmp/kernelbits_smumey.txt

After finishing the install:
chattr -i /tmp/kernelbits_smumey.txt

Comment on Tibco EMS with database backend (postgresql) by jens

Hi Jeff,

I downloaded the EMS 5.1, used a fresh installation and got the same error.
The solution is rather simple. As the error states, the process cannot find the stores.conf file starting from the tibemsd.conf. Starting with that error I fired a strace up and got to the following line in the log:
stat(“\”/home/jens/tibco/ems-conf/tibco/cfgmgmt/ems/data/stores.conf\”", 0x7ffc449705d0) = -1 ENOENT (No such file or directory)

-> As you can see, TIBCO reuses the quotes in the actual filename. If you unquote the stores.conf entry in the tibemsd.conf the application works fine.

Further to that I found that the classpaths for the “dbstore_classpath” had changed. Here I just used the absolute path to be sure.

I”m having the same problem as Harti with EMS 5.1.2. The stores.conf file exists:

-rw-r–r– 1 tibco tibco 2162 Oct 28 11:49 stores.conf

And contains entries for the DB stores. But the error keeps popping up:

Hi,

I’m sure you figured it out by now, but just for the record.
The stores.conf file will be generated automatically by the EMS on the first startup. So just start the EMS with the default config an then use the stores.conf generated.
A college of mine also mentioned one exception to this behavior with EMS 6.0. With the new release this seems no longer to work. In order to get a stores.conf he had to create an empty file called stores.conf and then start the server. After that the server would write its config to this file. Why TIBCO changed the behavior to this really is a mystery to me.

Regards,
jens
