001 – Error by select the Namespaces node
Question: I’am using Cache 2009.1, apparently the application connects to the server however, when I try to click on the Namespaces node, the following error appears:
Caché Monitor-Version 0.57
Java Version 1.6.0_15
VM Name Java HotSpot(TM)
Client VM Driver Version:2009.1.1.504
com.intersys.objects.CacheException at com.intersys.cache.jbind.ReadOnlyDatabase.parseStatus(ReadOnlyDatabase.java:1640) at com.intersys.classes.CPPStoredProc.getJavaClassDef(CPPStoredProc.java:1774) at com.intersys.cache.metadata.CacheClassMetadataImpl.

Fix this behavior by changing the default namespace of the Server registration. Go to the Server Properties (right click on server node -> properties) and change the default namspace from %CACHELIB to e.g. SAMPLES. You find more details about this topic: here
002 – Caché Monitor didn’t start properly:
Question:When I launch Caché Monitor, a splash screen is projected, but then nothing else occurs. If I check the process monitor on my XP machine, I see that CacheMonitor.exe is running, but nothing happens and there are no other screens.
This behavior occurs if you haven’t extract the entire zip file from Caché Monitor. Caché Monitor are missing important files and can’t start properly.
In the zip file is a folder called “lib” this folder is mssing in your installation folder.
Extract all files and folders from the zip file into you installation folder and start Caché Monitor again.
003 – Communication link failure
I can’t connect to my Caché Server, i always get an “Communication link failure”
If you register a new server in Caché Monitor the default Port is 1972. This can be the wrong port! If you get a “Communication link failure”, please check the port first. You can do that by open the “Server properties” dialog:
Here are some Information about the port handling in Caché:
Caché 2007.1 and above chooses the default ports for installation differently from previous releases. The new algorithm is: If port 1972 is unused, choose it. Otherwise, choose the first available port number equal to or greater than 56773.
Caché 5.2 does it in this way: Use 1972 or the first available subsequent number.
004 – User are not allowd to query for namespaces
Question: My connection is not allowd to use the %SYS namespace. What can i do?
Answer: If your account haven’t the right to access the %SYS namespace wich is the needed for the namespace list you can disable the query for namespaces.
006 – How can I transfer a single computer license to another computer
Question: I wish to transfer my Caché Monitor Single Computer license to a new PC. Are there any instructions on how to deactivate the license from the existing PC?
Answer: This can’t be done by a Caché Monitor User itself. You have to contact support with detailed license information, so they can remove a previous activations. After this you can activate on another machine.
