If one fails then it is must to restart from step 1? Or one can re-start the process from step3? Is it necessary http://www.dbforums.com/showthread.php?627619-HADR-problems one take every time 0 level backup if answer is then why it is require? Is there any alternative? I found an alternative but it some time work some time not i.e. the following If HADR not established after applying all steps then 1 down the primary server 2 down the secondary server 3 bring up the secondary server 4 bring up the primary server Note:- Do not bring up the primary server until secondary server writes in log files following lines DR: Cannot connect to primary server DR: Turned off on secondary server In this way primary can connect to the secondary server and replication would be started. Once I established HADR this way. Now I'm trying again I’m facing problems while I’m bringing up secondary server it writes following lines in log file: 02:33:59 Event alarms enabled.

replication of one instance to another, to add resilience. Should the master (or primary) instance fail the replicated (or secondary) can be switched to read-write (or standard) mode, either http://www.oninit.com/reference/index.php?id=hdr.html automatically or manually. The secondary instance can also be used as a read-only instance whilst replication is running, perhaps processing reports to take some load from the primary. What isn't it? It http://support.novabackup.com/customer/portal/articles/1774876-dr-%2250003-99-65%22-fail-in-1-minute-error-c0000001-50003-99-65-and-error-unexpected-failure-backup-failed-due-to-invalid-credentials-specified-for-the-destination isn't Enterprise Replication, which allows databases to be distributed across multiple servers. This is designed for scenarios such as regional offices having their own servers and instances, with all data replicated to a failed to head office instance - each regional database contains only local data, but the h/o database is a read-only (or read-write) composite of all the regional databases. This does not add resilience, nor is it designed to. In version 9.40 it is possible to mix the two, e.g. the primary server can be part of an Enterprise Replication topography, the earlier releases do not allow such a dr failure recovery setup. How does it work? Essentially the secondary server is in permanent logical recovery, it has done a physical recovery from the primary's level 0 archive, and is continually rolling forward logical log activity from the primary instance. Logical log entries are copied to the replication buffer, and this is transferred across the network to the secondary. It therefore follows that only loggable activity is replicated, if there are any unlogged databases on the primary server they will not be replicated to the secondary. Neither will any blobs which are not held within blob spaces (smart or otherwise). What do you need: The server Another server, with the same version of the Informix engine installed. The two servers must be at least the same manufacturer, o/s version and architecture. One could use a 4-way Sun E450 as the primary, and a 2-way E280 as the secondary, but not a E450 primary and a Sparcstation 20 as the secondary. It's quite common to use a somewhat lower specification server for the secondary, just make sure it can keep up! What do you need: The instance The dbspaces must be similarly configured on the tw

DR "50003.99.65" fail in 1 minute, Error: c0000001.50003.99.65 and error: unexpected failure: Backup failed due to invalid credentials specified for the destination NovaBACKUP Last Updated: Dec 04, 2014 08:15AM PST Disaster Recovery job(s) targeting a network path for the storage location whichfailin thefirst minuteof executionwith an error code ending in "c0000001.50003.99.65". This will occurfor one of two reasons, one is that your destination storage device is a network storage location such as a NAS or network share. If that is the case you will need to create a Device in our software in the "Device" tab for your NAS and be sure to enter the Username and Password for the user with full access rights to the Share that you are pointing our DR image/backups to (for example\\NAS\Backup\), that is usually the same username as the admin user of the NAS that you utilize to log on to the NAS's management interface. The Manual Disaster Recovery Backup job cannot be utilized to point to the "Device" of your NAS only the "Scheduled Disaster Recovery" job can do that. You can tell if you are using a Scheduled Disaster Recovery job if the log file for your Disaster Recovery shows that the destination media nameis "BackupImage-xxxx.ndf", if it is BackupImage in the name then it means that is a manually created Disaster Recovery job. AScheduled Disaster Recoveryjobusesa custom name set which would never be automatically named"BackupImage-xxxx.ndf", which is how the Manual DR job is created as. A guide onhow to create a Device in NovaBACKUPwhich shows screenshots is here, shown in "Step 1" of theguide here: http://support.novabackup.com/customer/portal/articles/1708948 An example log output for this type of error code for aDisaster Recoveryjob (54623687.dr.txt) would look like this: Destination:\\NAS\Backup\BackupImage-20141111.ndf [DRTAGID]:1 ERRO "Engine.cpp(814) unexpected failure: Backup failed due to invalid credentials specified for the destination."
