Re: Unable to start EMS

Some other process has acquired a lock on the file and the EMS server is trying to gain access to the file when the lock hasn't been released by the earlier process.

Its quite possible that the same log file is configured within multiple EMS servers you may have configured on the server.

Re: Unable to start EMS

Could you try flock -u ../datastore/async-msgs.db and flock -u ../datastore/sync-msgs.db?

This should release all the locks on the file. If this doesn't work perhaps you could consider a machine restart, but off-course this depends upon your environment if you could afford downtime.

You could also take some advice from some linux guru.

Re: Unable to start EMS

Hi Yeshodhan

Thanks for the timely responses.

One thing i observed is, when i try to run EMS from root user, its giving errors like

1)Creating store '$sys.nonfailsafe' file 'datastore/async-msgs.db' ...
Creating store '$sys.failsafe' file 'datastore/sync-msgs.db' ...
ERROR: Unable to open store file 'datastore/async-msgs.db', file may be locked.
ERROR: Unable to open store file 'datastore/sync-msgs.db', file may be locked.
Creating store '$sys.meta' file 'datastore/meta.db' ...
ERROR: Unable to open store file 'datastore/meta.db', file may be locked.
FATAL: Exception in startup, exiting.

2)Reading configuration from '/tibco/cfgmgmt/ems/data/tibemsd.conf'.
FATAL: failed to open log file '/tibco/cfgmgmt/ems/data/datastore/logfile'.
FATAL: Exception in startup, exiting.

I observed these errors in all unix platforms AIX, RHEL, SOL SPARC, HP,

And when i tried doing the same with non-root user, it works fine.

In documentation its given that, both root/non-root user should work.

Any other recommendations?

Thanks

Manoranjan

Re: Unable to start EMS

Hi Manoranjan,

on unix-platforms you have filemasks on the created datastore-files and logfiles. Please check this at first.

The first user who starts ems get this files writeable. My datastore-files have 644 (rw-r--r--) and belongs to non-root user.

Therefore the root-user fail with starting EMS, because tibemsd wants to open these files and have the writeable right.

Regards

Konstantin

Re: Unable to start EMS

Hi Manoranjan,

I suspect that your stores.conf file refers to a datastores in a specfic directory, however in tibemsd.conf file you were unable to find the path to stores.conf file. Assuming you took care of permission issues, please do the following and see if it works.

mkdir /opt/tibco/ems/Test/config and move tibemsd.conf & other config files to this directory.

mkdir datastore in /opt/tibco/ems/Test directory

In tibemsd.conf file make sure the store parameter is pointing to:

store = /opt/tibco/ems/Test/datatore.

The bottomline is when you have the a mismatch between the store parameter in tibemsd.conf file & datastore directory you usually get this error.

Try these out and let us know how it goes.

Re: Unable to start EMS

Hi,

I had the same problem while starting tibemsd. I installed ems as root and used setuid option. When I started tibemsd I always got error that log file cannot be opened. When I changed permissions on the folder where ems comfiguration files are kept, I was able to start tibemsd.

Siju

Re: Unable to start EMS

Hi Srini,

structure of tibemsd.conf file for EMS 4.x and EMS 5.x is different. I think you might the using a wrong configuration file for that particular EMS version.
