Crystal APS service connection unavailable

[dchant]

For past few weeks, our monitoring tool on another machine has been getting alerts that Crystal APS service is DOWN, when in fact it is still UP.

System working well for past 5 months on clustered environment.

We are using Robocopy to sync up files on the FileStore between 2 servers.

Most times but not all the time, it seems that during the Robocopy run, connection to the Crystal server and Crystal APS service is unavailable.

Hence we get the alerts re: Crystal APS.

Any suggestions as to reason for this to occur. Cannot recall any configuration changes in server/network. Was working well, then these alerts are occurring regularly now.

Have you looked at the event logs for your servers? You may also want too turn on the -trace option to assist you in trouble-shooting the issue.

The event logs has no records indicating that Crystal services have stopped. The server seems to "hang up" temporarily while the Robocopy is running.

The performance monitor and task manager show process usage about 40%. So there should be capacity to service at least some reports or even mapping from another machine.

Hi,
Since the FRS information is written to the APS, perhaps Robocopy's manipulation of the files is causing a write-back issue when updating the database..Or the contention between programs may be the issue if attempting to access the same file/directory ( Perhaps Robocopy locks files or changes access permissions during operation).

Personally,I would not have such a process ( or, similarly, a backup process) running during production hours..Have the replication done at night or use some other method of clustering that does not involve a separate 'copy' type process - ( Maybe a RAID or SAN solution)..
