Question David Foard · Mar 29, 2021 Purge strategy for parent-child persistent objects We are seeing performance issues in purging objects/tables that have parent-child relationships defined. Due to the number of child objects we're seeing very long duration to purge a single parent and all child tables. Is there a better way to do this and get a more performant purge task? I was thinking to purge the child tables individually first and then delete the parent is one way. Is there any other approach? David #InterSystems IRIS for Health 0 1 0 311
Question David Foard · Oct 13, 2020 FQDN ? Is there an undocumented class method that will output the FQDN? $SYSTEM only reports the part of the name concatenated with the namespace. Checking $SYSTEM.INetInfo doesn't provide the full DNS name, only a partial value that matches $SYSTEM. I can do a call out to the OS to get that value which seems to be the only way I can get the value. #InterSystems IRIS for Health 0 4 0 292

Question David Foard · Jun 12, 2020 Question on configuring /api/monitor for SAM I have a couple of questions regarding /api/monitor and configuring it to use with SAM. In our environment we only expose port 443, so even though I define the Web Application to use unauthenticated, SAM is unable to make a connection. Is there any alternatives to get this working? Also, even if there is a way to configure using port 443, unauthenticated access will never fly in our environment. Are there any plans to enhance SAM so it you use OAuth or even mutual TLS?

Question David Foard · Nov 15, 2019 Question on sharding Prior to IRIS, using ECP to share databases under heavy I/O load has known latency issues (in our environment), which pretty much restricted using shared database with relatively static or slow-changing data. In IRIS, will sharding mitigate the latency issue and allow any table to be shared? David #Sharding #InterSystems IRIS for Health 0 2 0 251
Question David Foard · Nov 7, 2019 Compatibility between %CSP.BinaryStream and %Stream.GlobalBinary? Is %CSP.BinaryStream compatible with %StreamGlobalBinary because reviewing the classes this doesn't look to be the case? What I am trying to do is zip large documents before sending over a REST interface. I compress the file and add that to an Ens.StreamContainer which is then passed to the operation to build the REST payload. We are using %Net.MimePart class to build the payload and use the BodySet method to add the zipped Ens.StreamContainer. The issue is when the REST interface receives the POST, it doesn't recognize the data as a zip compressed item. #Ensemble 0 1 0 232

Question David Foard · Dec 3, 2018 Using %INLIST in a SQL query using cursors I am trying to use %INLIST in SQL query using a cursor and the query fails to return results. It appears that the variable I use against %INLIST returns an empty string. All the examples I have seen use result sets and build the query as a string.
