Bug in Sharing Connection Cache between C and ActiveX components

I am using the sample PowerBuilder code that Sybase provides on their web
site.  In the README.TXT for the Server Code, there is this paragraph:

There is an issue that Sybase is still addressing
 with the sharing of a connection cache between a C component
 and an ActiveX component. This will affect the results from
 this sample application if any of the Powerbuilder component
 methods are called after a C component method made use of a
 connection within the same cache. Due to this issue if you
 execute either the RPC, GenerateResultSet, or OLE Automation
 portions of this application after the Datawindow portion of
 the application, you will not receive the intended results.
 Please exit the Powerbuilder client and restart the Jaguar
 Server before running it again.

I'm using Jaguar 1.1.1.  Has this been fixed in either the 1.5 or 2.0
BETA's?  Clearly if this issue still exists, it severly limits the use of
Jaguar in a Production setting.

Connection cache problems with Direct Connect on Jaguar CTS 3.6.1
Hello all, I need to connect to CICS and execute transactions using Jaguar CTS 3.6.1, powerbuilder component and UNIX Sun Solaris 8.0. I've made a connection cache (via Jaguar Manager) using Open Client driver and it seems to work fine, because i can ping it. But, the problem is: When i try to access the connection cache within a powerbuilder 7.0 component using the Direct Connect driver (DBMS property) and specifying the connection cache name in the DBParm property, in NT (Win 2K) the connection cache is not used (Direct Connect bypasses Jaguar), in Solaris 8.0 it says it do...

Connection caching on jaguar cts
I am using a Jaguar CTS connection cache in my jaguar component. As described in "PowerBuilder Application Techniques" I perform CONNECT in the activate() event and DISCONNECT in the deactive() event. The component works terribly slow, it seems, that the connection caching does not work: Tracing the odbc-api calls shows that the jaguar server performs SQLConnect() and SQLDisconnect() to the database instead of caching the connection. What might be wrong ? On Tue, 15 Feb 2000 17:53:20 +0100, Manfred Huber <Manfred.Huber@voest.co.at> wrote: > >I am using a Jag...

Where is connection cache info stored? - Can't find cache "props" files in \Repository\ConnCache

Shared PowerBuilder Components in Jaguar CTS
Is there any recommended way to use a shared component. We cached a subset of data from a table into a shared component (35,000 records) and use another component to filter data from that cache. It does not seem to perform very well. Would it make more sense to just have the middle-tier component hit the table directly. That's what I would do. The db will use a index to get the needed data. -- Dean Jones, CPD Professional Team Sybase dean@powerobjects.com PowerTeam, Inc. http://www.powerobjects.com Chuck Kiefriter <ckiefriter@caci.com> wrote in message ne...

Jaguar connection caches and stateless PB components
Hi all, I've encountered a strange ocurrence with my EAS-Web application. I'm using an EAS C5 configuration with PB 7.0.3 and PD 7.0.2. I reported earlier that I had a problem with the Jaguar server crashing when I put a bit of load on it while I specified the threads of both HTTP and Jaguar to over a 1000. The cause of this was the fact that I had instance pooling on for my PB components. When I deactivated this property for my PB components , It could handle 27 of the heaviest queries my application had ( 1 minute retrieval time, about 700 rows a query). SO far so good. ...

How can I resolve this problem? thanks Never tried it. Why are you using this option?

connection cache DBParm in PB jaguar component
I'm trying to use a connection cache from my powerbuilder component deployed in Jaguar. I set the transaction object as such: mytrans.DBParm="CacheName='myconnectcache'" The cache works fine when I use it with Java components within Jaguar, but does not work from within my PB component. The "ping" test in Jaguar manager works fine. I tried two different connection caches: a JDBC one and an ODBC (both of which I know are valid). However, I get an error when I try to do any database operation (no valid db connection) when attempting to use the ca...

Altering the connection cache used by Jaguar Components
All My application consists of a Powerbuilder client and a number of Powerbuilder NVOs deployed to a Jaguar Server. The server objects are stateless; they connect to the database through a connection cache in the Activate event and disconnect in the Deactivate event. I would like to modify these objects to use a different connection cache dependant upon a client side setting. The only way I can see of doing this is to move the connect to database code from the activate event into each function and add the connection cache name to every function as a parameter. Is this correct or i...

Jaguar CTS 3.5 Connection Cache to Oracle9I
We are in the process of ugrading Oracle to 9I and need to reconfigure the connection cache to look at the new database, however there does not appear to be a choice for 9I. (there is no radio button on the Driver Tab of the Connection properties for Oracle9i). We have not installed to Oracle9i Client Software on the Jaguar machine to date. (we are hesitant to due this until we are actually going to use the new database. Will installing Oracle Client fix this problem, or is something else needed?
