#System Administration

Hi,

We have an HTTP business operation where the messages gets stuck and we had to recycle the operation to resume the processing. We are trying to work around this (for time being until we find the root cause) using below code which should recycle the component.

During a Caché system management training course today we discussed structural database integrity (a.k.a. physical integrity) and the tools InterSystems provides for checking integrity and fixing problems.

Today I helped someone solve a mystery. He had been trying to use the -U namespace argument of a csession command to specify the namespace in which to run a particular routine, and was puzzled when the routine could not be found.

Since most of our customers moved to Caché 2015.1, some admins became abused with CPUPct warnings (sometimes alerts) in console log without other signs of lacking CPU power.
Documentation states that:

hi

I want to online backup one Caché database by windows bat, I find some article from the online documentation about terminal script and the ^DBACK tool and External Entry Points for ^DBACK, so I can invoke the External Entry Points for ^DBACK from terminal script like this: send: Do BACKUP^DBACK<CR>

Is there other better way for backup database from bat/script?

Thanks

Hello everyone.

I'm new to Caché.

I would like to know how I can connect my PHP application to the intersystems database.

Is it the same as MySQL?

Need help.

Thank you

A few years ago InterSystems announced a tool to help Caché system managers on sites with a large number of Caché instances. It was called Enterprise Manager.

When I recently searched for information about it I didn't have much success.

Have you ever thought about leveraging IIS (Internet Information Services for Windows) to improve performance and security for your Caché web applications?
Are you worried about the complexity of properly setting up IIS?

See the webinar Configuring a Web Server presented by @Kyle.Baxter, InterSystems Senior Support Specialist. Learn how to install IIS, set up it up to work with the CSP Gateway, and configure the CSP Gateway to talk to Caché.

I only recently noticed the presence of a local database named CACHE alongside the more familiar CACHESYS, CACHELIB, CACHETEMP and CACHEAUDIT.

A bit of digging through the documentation archive led me to conclude that the CACHE database arrived in 2010.2, where the release notes say:

Hello,

Usually I recommend to set the global buffer (GB) as large as possible in order to maintain in memory more globals as possible. I don't know if this is a standard recommendation, but I want to discuss what should be the best buffer size for a Ensemble instance that only process messages.

In this post, I am going to detail how to set up a mirror using SSL, including generating the certificates and keys via the Public Key Infrastructure built in to Caché. The goal of this is to take you from new installations to a working mirror with SSL, including a primary, backup, and DR async member, along with a mirrored database. I will not go into security recommendations or restricting access to the files. This is meant to just simply get a mirror up and running.

Currently, we have an application running in one namespace ("Database B") that has globals and routines mapped to another database ("Database A"). After enforcing clean up on Database A, we found that 90% of the disk is free. We would like to compact Database A and release the unused space. However, we are running OpenVMS, which seems to be the issue.

For databases consisting of only globals, we are able to use ^GBLOCKCOPY; however, we need to ensure that the routines and mappings are also copied.

I have been asked to assist in the planning of the a new server for our database, which we will be changing operating systems from OpenVMS to Linux (RedHat distribution). However, its difficult to find material regarding what would be recommended, which is likely due to the database being proprietary.

In looking at the information provided below and hoping to decrease processing time, would anyone be able to recommend type of configuration we should have for the new Linux server? Please feel free to ask any clarifying questions.
