When exporting using the Export() method of the %Library.Global class, if the export format (fourth argument: OutputFormat) is set to 7, "Block format/Caché block format (%GOF)," mapped globals cannot be exported (only globals in the default global database of the namespace are exported). To export mapped globals in "Block format/Caché block format (%GOF)," specify the database directory to which you want to map them in the first parameter of %Library.Global.Export().

An example of execution is shown below.

The maximum number of namespaces that can be created in one instance is 2047. However, to use a large number of namespaces, you will need to configure memory accordingly.

The maximum number of databases (including remote databases) that can be created in one instance is 15998. Depending on the type of license, there may be restrictions on the number that can be created. For details, please refer to the following document.

In SQL, NULL data and the empty string ('') are different data. The method for setting and checking each is as follows.

(1) NULL data

[SQL] 

insertintotest(a) values(NULL)
select * fromtestwhere a ISNULL

[InterSystems ObjectScript]

setx=##class(User.test).%New()
setx.a=""

(2) Empty string ('')

[SQL]

insertintotest(a) values('')
select * fromtestwhere a = ''

[InterSystems ObjectScript]

setx=##class(User.test).%New()
setx.a=$C(0)

For more information, please refer to the following documents:

This can be achieved by using the CSV() procedure of the %SQL.Util.Procedures class.
Below is an example of usage code. (Assuming that the file test.csv is in c:\temp.)

If you do not specify the option to remove the mirror attribute of the mirror database when deleting the mirror configuration, the database cannot be restored to a normal state and will be mounted read-only the next time it is mounted. To restore the database to a read-write state, you must remove the mirror attribute using the system routine ^MIRROR.

The procedure is as follows (execute in the %SYS namespace):

To compile class routines including the mapped modifier, specify the compiler modifier "/mapped=1" or "/mapped". For example, do the following:

[Example 1] Get the class list and compile 

do$System.OBJ.GetClassList(.list,"/mapped")
 // build your classes starting from .listdo$System.OBJ.Compile(.list) 

[Example 2] Compile all classes 

do$system.OBJ.CompileAll("/mapped")

$ZTIMESTAMP returns the date and time in UTC format, so to change it to the local time zone, use the following system method: 

$SYSTEM.Util.UTCtoLocalWithZTIMEZONE($ZTIMESTAMP)

The above output will be in the format ddddd,sssss.fff.

    ddddd: Same format as $HOROLOG dates
　sssss: An integer indicating the number of seconds elapsed since midnight on the current date
　fff: Variable number of digits indicating the fractional part of a second

* Similar to $HOROLOG, except that $HOROLOG does not include fractional seconds.

Data for InterSystems products (table row data, object instance data) is stored in global variables.
The data size of each global can be obtained by clicking the properties of the global you want to view from the Management Portal > System > Configuration > Local Database > Globals page, and then clicking the Calculate Size button on the Global Attributes page that appears.
To display the data sizes of globals in a namespace, you can call ^%GSIZE utility on the terminal.
The method of execution is as follows.

After upgrading your system, you may receive the error below when you try to open the Management Portal:

ERROR #5001: Server version of object does not match version sent from the client: %ZEN.Component.vgroup

This error is caused by outdated information remaining in your browser's cache.

You can resolve the error by clearing your browser's cache.

If you restart the OS after changing the machine name without stopping InterSystems IRIS (hereinafter referred to as IRIS), a problem occurs when IRIS cannot start.

To get started, delete the <installation directory>\mgr\iris.ids file.

iris.ids file stores the started node name and shared memory information (shared memory ID). It is created when IRIS starts and deleted when stopped (iris stop or iris force). If you stop (restart) the OS without stopping IRIS, iris.ids, which contains IRIS startup information, may remain.

To run an online backup from a command you can use the API BACKUP^DBACK routine.
An example of performing a full backup is as follows.

set  status = $$ BACKUP ^DBACK( "" , "F" , "full backup" , "c:\backup\full.cbk" , "Y" , "c:\backup\full-log.log" , " NOINPUT" , "Y" , "Y" , "" , "" )

The return value is 1 if the backup is successful, and 0 if the backup is unsuccessful. Please refer to the log file for details on failure.

Additionally, you can specify C for the second argument TYPE to specify a cumulative backup, and specify I to specify a differential backup.

InterSystems FAQ rubric

You can set the maximum size of the IRISTemp database at IRIS startup by setting a configuration parameter called MaxIRISTempSizeAtStart.

After setting, the system will truncate IRISTemp to the set value (MB) at the next IRIS startup. If the current size is less than the specified MaxIRISTempSizeAtStart, no truncation will occur. Also, if 0 is specified, truncation will not be performed, so the size will start without changing. (Default) Settings are made from the menu below.

Hi,

My customer is implementing HL7 validation using EnsLib.HL7.Util.Validator.Validate in an HL7 production.
They set validation spec "dmr-z" because they want to allow unrecognized Z-segments and verify the presence of required fields.
Despite using "-z", Z-segments are not allowed and the following error occurs:
<Ens> ErrGeneral: Cannot validate segment schemas without a category.Unable to validate segment 8: ZPR.
Aside to that, when the verification spec is “dm-z”, the Z-segment is allowed as expected.
Can 't "r" and "-z" be used together? 
Is there any other way to implement both validations?
