I have a database with almost 1T of free space. I want to run the compaction process to reclaim and subsequently free that space. I am aware that this process is a background process but will the level of processing required to move this volume of space to the end of the file to allow for reclamation impact system usage while this process is running. Essentially, does this process run at a low priority and use processing as available. I am trying to determine if I should run this over a weekend or can this be run at any time.
InterSystems Certification has redesigned their IRIS System Administration certification exam, and we again need input from our community to help validate the topics. Here's your chance to have your say in what topics are covered on the InterSystems IRIS System Administration Specialist exam! And, yes, we'd like to hear from you Caché admins too!
Here's the exam title and the definition:
InterSystems IRIS System Administration Specialist
Has anyone found a good terminal emulator replacement for Cache Terminal?
We want one where the up arrow works to bring back the last command typed (without extraneous characters appearing at the beginning of the line) and be able to run D ^JOURNAL and have it display correctly.
I tried WebTerminal a couple of years back and but it didn't work properly with the journal. I've tried RoyalTS and that doesn't do up arrow or the journal correctly even though it's supposed to be emulating a VT400.
I have a question about how to modify a XData Block programmatically . Assume i have a impl.cls and there is a XData Block (like XData OpenAPI [ MimeType = application/json ]) in the impl.cls. In other class, can i write a fucntion to modify the context in the XData Block?
Ps: The document already show how to read the XData blcok, if i want to insert something into the block and save it back, how can i do this programmatically (eg write a method and read the block from other class, write something into the block and save it ) ??
Impedance mismatch is a term commonly used to describe the problem of an object-oriented (OO) application housing its data in legacy relational databases (RDBMS). C++ programmers have dealt with it for years, and it is now a familiar problem to Java and other OO programmers.
The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.
In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.
Pass multiple values from one class to an excel report class using multiple tabs?
I want to request the data in the request class using a SQL statement changing values in the SQL statement, and then parse the values to the excel report to each sheet respectively.
I setup an account in Cache and when I try to sort the dictionary item in the file by using the command SORT DICT filename, where filename is the name of the file i.e. SORT DICT TEST, I get the following error CMQL: The DICT entry "FIELD.ASSOC_" is not defined
The LISTDICT works correctly. Any thoughts on how to correct this error?
Maybe I haven't seen anything about it in the documentation, but why isn't there a way to list all the Resources from the %SYS namespace from a class rather than through ^SECURITY
Thinking maybe something like this: ##Class(Security.Resources).ListAll(.result)
As more people join Developer Community, and with increasing efforts to promote code sharing, I'd like to draw fresh attention to this post I wrote a year ago. It spotlights a feature within the class compiler which is both useful and dangerous. When importing code (e.g. from an XML export of classes received from someone), it's worth considering the risks.
Even if that post doesn't seem relevant to you at the moment you may wish to note it for the future. A handy way of doing this is to click the star icon at the end of it.
I have embedded html within a <script language="cache" runat="server"> block. Within that I'm defining and using a macro, but it doesn't display at all. Something like:
For volatile tables (tables with many INSERTs and DELETEs), storage for bitmap indexes can become inefficient over time.
For example, suppose that there are thousands of data with the following definition, and the operation of bulk deletion with TRUNCATE TABLE after being retained for a certain period of time is repeatedly performed.
Looking for a way in which I could possibly pass a flag through a property when performing an Insert statement, on a mapped class.
insert into my.class (serialNumber, modelNumber, myFlag) value ('testSerial', 'testModel', 0) myFlag is not stored in the DB.
The mapped class then calls a legacy routine (MAC) via CodeMode = 'objectgenerator', (Insert method within the 'objectgenerator')
Within the legacy routine, I am setting an index... but I don't always want to set it (multiple inserts, and I will only set the index on the LAST insert)
I have created a view to stage some data in a different format and then want to reference that view in a SQL query from a table that filters the data from the view using a property of the table.
Example:
select MsgId, FileName, (select ReportName from custom_view where MsgId = ReportId ) as ReportName from main_table
Is this even possible? When I try this, I get an error table not found for the view?
