we use Rose to do HA with cache2016.2, the database is placed on the hard disk array, which is essentially an instance, and the same array disk is mounted by rose switch, another mirror machine is made.
Is there any problem with this structure for disaster recovery and backup, I hope to give some advice. Thanks!
I am trying to populate a table using the sql Data Import Wizard. The input file is a tab delimited text file. But the import keeps failing with a 104 error showing validation for the columns which use %Library.TimeStamp and %Boolean datatypes is failing. Yet when I insert values into the table through a SQL insert command, the values get saved correctly in the table.
For the TimeStamp format in the wizard form, I am choosing YYYY-MM-DD-HH:MI:SS because there was no option for this format: YYYY-MM-DD HH:MM:SS.
I'm using a JDBC driver to connect PGSQL -> Cache. I'm noticing when I run SELECT queries and COUNT(*) command against the same table, I get different result sets. I'm pretty new to Cache in general - so I'm trying to understand why these would be different.
Examples (TransID and InvNum should occur in every "row"):
SELECT COUNT(*) FROM ACCT.Services = 1,090,324 WHERE ACCT.Dept = 483
SELECT TransID FROM ACCT.Services = 1,085,776 WHERE ACCT.Dept = 483
SELECT InvNum FROM ACCT.Services = 586,023 WHERE ACCT.Dept = 483
We've traditionally run a selection of development environments from a single cache instance using different namespaces for DEV TEST PREP etc. This has come with a few drawbacks, mainly that you then cant break down into namespaces per environment and everything is sharing various options.
Is there a massive overhead to running multiple cache instances from the same 'box' instead?
How best to share the memory setup in that situation, we usually pre-define around 80% for the instance, do we just share that evenly between the multi instance scenario?
I have some code in a mac routine that use indentation and the "." character :
IF condition1 DO
.WRITE YCR,...
.WRITE YCR,...
.WRITE YCR,...
I would like to add a try / catch block between the write statements. I can't refactor the whole code and use indentation with curly braces instead (there is too much code, not written by me)
I have tried the following but it does not work (it compiles, but code stop running right before the try keyword)
I have run into two annoyances when using VS Code for server-side editing of Objectscript and was wondering if anyone knows of any solutions or workarounds.
1. In .mac routine files, class names that aren't fully qualified (e.g. ##class(example) instead of ##class(Package.example)) fail to be understood, so the class will have a red squiggly underneath it and a problem that reads
"Class 'example' does not exist. InterSystems Language Server".
I am using MDX2JSON do display data, it uses CSP REST to retrieve data and uses Password Authentication. I enabled LDAP authentication for this applicaiton, but it does not work.
I have a requirement to delete the Ensemble interfaces , as per User request. I would like to write a routine for that and once I execute, it should remove the interface components through code. Could you please provide code samples for the following actions ?
Deleting an individual rule from a rule class
Deleting a class from Ensemble
Deleting a Host (Service/Operation/Process) from the Production.
we read data from an Oracle database. The desired order is created by an 'order by' in the sql statement. The individual elements of the result set are converted into objects and inserted into a parent object using 'insert' on a property, which implements a one-to-many relationship with the result objects. Later, we iterate over the objects in a for loop and process the contents. At this point the order is apparently no longer identical to the order in which the elements were inserted.
There is an undocumented command, $preprocess, that can be called as below. In this case it takes the class name and converts its code into a text array. That includes comments as well. Two questions about it if you know:
I have a REST client that calls a REST service and as a response gets a stream containing a JSON structure. The service is placing some weird non-printable characters into some places in the JSON document that is throwing off parsing of a down-stream XML document.
What I would like to do is just remove the non-printable characters from the response stream that comes back from my call to the REST service.
Does anyone have a handy utility or method for removing all non-printable characters from a character stream?
