How To Determine Secondary Database State With RDBSyncForward?

Hi, We are using redundant Oracle databases using RDBSyncForward, setup as per the ETM White Paper "Oracle Historian Replication EN". My question is: how can I tell if the connection to the secondary Oracle database is healthy? I see we have the internal DPEs _RDBArchive.dbConnection.connected to le...

Re: Problem moving offline archives to backup (RDB/Oracle)

We managed to trace the cause of this issue and I'm happy to say it is now resolved. The second error message was the clue: C:\app\oraclehome\product\12.2.0\ client_1 \bin\rman. It seems that during the original RDB installation the RDB_config.sql file had been set up to point at the Oracle bin dire...

Re: Problem moving offline archives to backup (RDB/Oracle)

A bit more information: we are running v3.16 patch 12 and Oracle 12.2.0.1. Like I said, the WinCC OA log is not throwing up any errors, but after digging around on the internet, it seems that the ARC_LOG table is a good place to find any Oracle errors. Sure enough, there are 3 errors in the ARC_LOG ...

Re: Force Write to Oracle

Thanks for the reply Leopold. I understand your point about not being able to detect PLC changed data. I think the use case is that archives are deleted fairly regularly. e.g. imagine archives are deleted weekly, but a particular DPE last changed 2 weeks ago, then changed again today. If you run a r...

Force Write to Oracle

Hi, On my project there is a requirement that for all DPEs with archive configs, there shall be at least one value sample logged in the Oracle database per hour, even if the value has not changed. Is there a way to force writes to Oracle in this way? We are using 3.16 with RDB archiving using redund...

Stop Trend Auto Scroll

Hi,

Is it possible to stop the trend widget from automatically scrolling when the trend line (i.e. the current time) reaches the right hand edge?

Thanks.

Re: Remove DialGauge Needle Shadow

Thanks for the suggestion but it does not address the question.

Can anyone at ETM confirm if removing the needle shadow is possible?

Remove DialGauge Needle Shadow

Apologies if this has been asked before - how do you turn off the needle shadow in the DialGauge widget?

With our colour scheme the shadow is prominent enough to be distracting.

Thanks in advance.
