Hi,

I am trying to support a use case where a test instance is created from a production backup. At a high level, the process works by mounting all relevant file systems and then bringing the instance up. This works well as long as the file systems are mounted using same mount points as the source instance. However, I would like to support a case where file systems are mounted using different paths.

Hi,

I am wondering if there is a way I can change the GUID of an instance. The use case is that I am restoring from a backup on an alternate host and start the instance there. However, the restored instance ends up with same GUID as that of source. Is there a way I can tell this newly restored instance to use a different GUID?

Thanks,

Raghu

Hi,

After restoring all the Cache related files on a machine, I am performing journal recovery using the command "^JRNRESTO". It works as described in the document and the recovery succeeds. However, the command is interactive. Is there a way I can run it in a programmatic way? I don't want to just supply a text file containing answers to all the prompts. I am wondering if there is way I can pass all the information upfront to the command.

Thanks,

Raghu

Hi,

I am placing Cache instance in backup mode by using the command:

csession <INST> -U%SYS "##Class(Backup.General).ExternalFreeze()"

and I see in the console log a message similar to follows:

"Journaling switched to: /cache/mgr/journal/20170330.002"

Now, is there a way to programmatically find out this journal file name? In fact, I am interested to find out the journal file that is switched. For example, in the above case, that would be "20170330.001".

Thanks,

Raghu

Hi,

I am exploring a simple restore procedure for a Cache instance and would really appreciate any help.

Basically, I have a CentOS machine with a Cache instance and let us say I backed up all the mount points where Cache data is located (install dir, DAT files, journals, WIJ etc). On another identical machine (without Cache installed), I mounted all these file systems exactly using the same mount points so all the data is back with the same paths.

Hi,

I am trying the following command in order to freeze the instance before backup is done:

csession CACHE -U%SYS "##Class(Backup.General).ExternalFreeze()"

The command requires user name and password to be supplied when prompted. Is there any way that this command can be run where it doesn't query the credentials? I am wondering if it can use OS level permissions (root or effective user who owns Cache processes etc) .

My test is on a CentOS 6 machine if that helps.

Thanks,

Raghu

I have posted my first question in "Cache" forum this morning and since then, I started receiving emails whenever a new topic is posted. I don't want to receive such emails and looked for a way to tweak for "email preferences". However, I couldn't find any such option. Can someone please tell me how I can stop emails for all the posts?

Thanks,

Raghu

Hi,

I have downloaded an evaluation copy of Cache and installed on a Windows 2016 R2 machine. I wanted to Configure different locations for DAT, WIJ, and Journal files but the installation process didn't give me such a "custom" option. I do see that the installation guide mentions the presence of such an option so I am wondering if this is a limitation of evaluation copies. Can someone please confirm?
