Mirroring

Syndicate content 12 

I have a DR Mirror   with a WIJ that is 5 times as large as the Primary Failover member. My Read-Write Reporting mirror WIJs are the same size as the Primary.  I don't  know why the DR WIJ i so large and would like to shrink it to the same size as the others.  Any suggestions are welcome. Thanks!

Hi guys

I've added a new mirrored failover member to an existing one.

They are both Arbiter controlled.

When I do Add database to mirror on the primary I'm always getting an error. Missing Mirrored database.

I followed everything in the documentation and always get the same error.

I've copied the CACHE.dat file after umounting the database on both servers. then mounted them.

Could you help me out?

 

Kind Regards

Hi, would really appreciate your advice on how I can restart the mirror-monitor. I've followed the instructions and restarted the mirror monitor, and still the status seems to be down. Can you point me to some resource or steps that I can follow ?

I logged into %SYS terminal and restarted the mirror monitor and it says that it is running

In System Administration | Configuration |  System Configuration | Journal Settings there is a check box for Freeze on error.

From reading the documentation, it sounds like the choice to freeze on error is one of system availability vs system integrity.

Curious to know whether Ensemble users choose to freeze on error or not.

If you have a best practice recommendation based upon your experience or knowledge, that would be helpful information too.

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

 

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live.  Or does this even matter?

I need to have both Cache and the Mirroring Arbiter startup when the HP UX system starts.  Having not worked on HP UX much I am not familiar with the method for accomplishing this.

I would appreciate any information or even sample scripts that would help resolve this.

Hi All

I'm looking for some field experiences, lessons learned, or actual deployed solutions to the problem of replicating non-CACHE.DAT data in a mirrored Cache environment.  

Environment:

  • Operating System is IBM AIX
  • Hardware is IBM Power w/ virtualised storage
  • Cache 2017.1
  • 2x Production mirror members
  • 1x DR mirror member

 

There are a number of different data types that we're looking at mirroring, and a number of identified solutions.  The two main types of data to be mirrored outside of Cache mirroring are:

Hello,  Thanks in advance for all replies.  I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks.  I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues.  Now I am setting it up in lockdown mode with encryption and this one is testing me.  I have everything setup but my async dr member cannot connect to the primary.

Hi,

Initially when setting up a cache instance one creates or imports the user/ resources roles etc .

After the Mirror has been activated you can add users, resources etc. But when trying to add new SQL Table privileges to a namespace where the databases are mirrored it seems that you are not able to , Getting error: 

ERROR #5002: Cache error: <DIRECTORY>SQLUserPrivsExecute+13^%SYS.SQLSEC

SOURCE ELEMENT: %CSP.UI.Component.SQLTables (SQLTables)


How do you maintain these privileges?

I have setup an async reporting mirror member with Read only access.  My problem is that if I try to do any sql reporting against that data I am getting errors.  I am sure that this is because the DB is read only, but I had assumed that setting up a reporting mirror would handle this.

 

I there a setting or mapping  I am missing?
