Integrated Jco Version on NW 740

[former_member217468]

Hi ,

we have an NW Portal 740 SP10 system installed and trying to figure out the JCO version, would anyone know how to check it ( we need to know that for  setting the MAX_CPIC_CONV parameter as per SAP note 2124330

SAP NetWeaver Application Server Java release 7.1X and with JCo 3.0.X, the maximum number of CPIC conversations must be set via the Java property jco.cpic_maxconv.

I can see the following from system info , but that does not correspond to version 2 or 3 of JCO

Thank you

Hello Jonu,

com.sap.mw.jco belongs to JCo 2.x

com.sap.conn.jco belongs to JCo 3.x

You get this result because you filtered for *mw*, but that way you will only see the JCo 2 component. Please remove it and and the JCo3 will also appear. On 740 we have JCo 3.

See Implementation Considerations section on this page, for information about why you see both versions here.

Best Regards,

Peter

Thank you Peter, i can see both the jar files on our portal , so if both the files are available how does the portal know which one to choose, and lets say if we remove the (com.sap.conn.jco belongs to JCo 3.x), will it then choose Jco 2.x

Hi Jonu,

You do not need to remove or disable anything. They (both) are there by default and for a reason.

But it is up to the application which API will be used. If an application was developed for 3.x, it will use 3.x. Since the APIs are very different it is not like the way you described (you remove one and it would jump to the other).

Best Regards,

Peter
