Re: Session count
Hi Calvin,
My app was already fetching the application().activeSessionsCount() from
the server every 30 seconds.
So now in the same DirectAction I also update a new small table in my
database with a row for each of my instances and two columns(Instance ID,
active count). I can now fetch this data and display the active counts of
the other instances of my app. I had to add a little extra so that when an
instance's last session terminated the count in the database would go down
to zero, to do this I overrid the terminate() function in Session.java to
something like this:
public void terminate(){
// If this is the last session on the instance we update the DB session
count to 0 before terminating it
if(this.application().activeSessionsCount() == 1){
EOEditingContext editingContext = this.defaultEditingContext();
String instanceId =
String.valueOf(this.context().request().applicationNumber());
WebInstance instance = WebInstance.fetchRequiredWebInstance(editingContext,
ERXQ.equals(WebInstance.ID_KEY, Integer.valueOf(instanceId)));
instance.setActiveCount(0);
editingContext.saveChanges();
}
}
super.terminate();
}

Re: get active session count for all instances
Thanks Marco, I found a solution to this. Yes I have got all this in my JavaMonitor, but I needed to retrieve the info in java to display on screen from within one of the instances. So now I just continuously update a small table in a database with the active counts of each instance.

get active session count for all instances
Hi all, I'm not sure this is possible but is there an easy way to get the total number of active sessions in all the instances of an application? We have 4 instances of the app in a javamonitor, this.application().activeSessionsCount() will return the count for the current instance only, whereas I'd like the sum of all 4. Thanks in advance!

Virtual Column equivalent in EOModel ?
Hi, In one of my Oracle tables I've got a virtual column. In my EOModel I had to set this field as Read-Only in order to do an Insert in this table. Otherwise the generated SQL included this field and an Oracle error occured. My problem now is to edit/update a row in this table because even with this field as Read-Only in the EOModel the generated SQl includes this field in the 'Where' clause of it's 'UPDATE' query. Is there a certain way to set this field in the EOModel for it not to be included in the sql for an edit/update? Or should I just use rawrows?

ERXExistsQualifier
Hi, The ERXExistsQualifier currently doesn't seem to work when multiple tables are referenced in the 'exists' condition. I think a few people are already aware of this but could anyone tell be if they know a way to work around this ? Because the only alternatives I see are either redesigning tables in my database or trying to correct the ERXExistsQualifier.class myself. Thanks in advance for any advice! Here's the SQL output of two examples explaining why one works and not the other: 1) Example 1 - where the exists condition only refers to one table (works because OBS table is correctly aliased exists0) SELECT t0.* FROM PTF t0 WHERE ( EXISTS ( SELECT exists0.ID FROM OBS exists0 WHERE exists0.OBS_DATE BETWEEN date1 AND date2 AND exists0.PTF_ID = t0.ID ) ) 2) Example 2 - where the exists condition refers to multiple tables (doesn't work because OBS table is aliased t0 instead of exists0, ...and the PTF_LOC table shouldn't be aliased T1 either) SELECT t0.* FROM PTF t0 WHERE ( EXISTS ( SELECT exists0.ID FROM OBS t0, PTF_LOC T1 WHERE T1.LAT BETWEEN -40 AND 91 AND exists0.PTF_LOC_ID = T1.ID AND exists0.PTF_ID = t0.ID ) ) Next exception:SQL State:42000 -- error code: 904 -- msg: ORA-00904: EXISTS0.PTF_ID : identificateur non valide ...And here's the 2 equivalent queries but with the IN qualifier(same problem): 1bis) SELECT t0.* FROM PTF t0, PROGRAM T1, MASTER_PROG T2, PTF_STATUS T3 WHERE (t0.ID IN ( SELECT exists0.PTF_ID FROM OBS exists0 WHERE exists0.OBS_DATE BETWEEN ? AND ? ) ) 2bis) SELECT t0.* FROM PTF t0 WHERE (t0.ID IN ( SELECT exists0.PTF_ID FROM OBS t0, PTF_LOC T1 WHERE T1.LAT BETWEEN ? AND ? AND exists0.PTF_LOC_ID = T1.ID ) ) ___ Do not post admin requests to the list. They will be ignored.

NSTimestamp
Hi, what is the simplest way these days to convert a string or Date to NSTimestamp ? I can't seem to use SimpleDateFormat because java.util.Date cannot be cast to com.webobjects.foundation.NSTimestamp ...

Best way to use raw SQL

[no subject]
Is there a known bug on ERXExistsQualifiers? The generated SQL code is false. It compares the primary keys of both tables instead of the foreign key and primary key as specified in the relationship. Someone posted this same bug in 2011, has anyone been able to use them since and otherwise what would be the best alternative ? ___ Do not post admin requests to the list. They will be ignored.
