Hash values of columns

I try to find a function, which generates hash values of columns. In MS SQL Server I can use

select hashbytes('sha2_256', my_column) ...

to create hash values of my_column. Is it possible to use such things in Caché?

Thank you
André

Whenever the Windows SNMP Service restarts, the snmpdbg log says the following.

13:08:59 :Attempting initial TCP connection(s) with 1 Cache instances ...
13:08:59 :Get connection with ENSEMBLE on port 1972
13:08:59 :Connection refused on port 1972, check if Cache instance ENSEMBLE is started.
13:08:59 :Cache iscsnmp.dll initialized for 1 configs

Ensemble and all productions are running. I've set up Caché SNMP agent on many other servers in our company and those are working fine. However this one server won't budge.

$ZF(-100,..) issues

Hi, I found some issues with $ZF(-100) whilst replacing our old $ZF(-1) calls following the security alert. They're easy enough to work around, just figured it might be useful to someone :)

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

Let's say I have this simple script file try.script

write 1
write 0

I can execute it in a terminal (csession) by calling:

csession cache < try.script

And I get the following output:

%SYS>
1
%SYS>
0

However I want to use a try catch block in my script:

try {
write 1/0
catch {}
halt

But as script is executed line by line, it's interpreted like this:

Python has become the most used programming language in the world (source: https://www.tiobe.com/tiobe-index/) and SQL continues to lead the way as a database language. Wouldn't it be great for Python and SQL to work together to deliver new functionality that SQL alone cannot? After all, Python has more than 380,000 published libraries (source: https://pypi.org/) with very interesting capabilities to extend your SQL queries within Python.

Hi,

I am trying to load all the data tables from one iris server to a client server but some of the tables data failing to load all the time. But I can load around 100 tables successfully but 8 to 10 tables are failing all the time. I made an IRIS odbc connection using odbc driver to load the data from tables.

Also I can see read server loop error message on the iris server side as the same time the table loading fails.

Please find the screen shot attached which shows the error on client server.

Hello; we have users on the system with cache logins. They have access to a specific namespace, and no access to %SYS of course. I'd like to give each user the ability to change his own password from within our application, using Security.User.PasswordExternal. This only exists in the %SYS namespace, and the average user can't get to it.

Should I give the users access to this column in this table (column Password, table Security.Users)? What about access to the namespace? Is this possible? Has anyone done this before?

Thanks,

Laura
