Implementing the Library Upgrade for SAP Snap Pack
Overview
The following SAP libraries for SAP Snap Pack are upgraded. The JCo library also depends on a native library which needs to be updated:
JCo from 3.1.4 to 3.1.10
IDoc from 3.1.1 to 3.1.3.
Implementation
The SAP JCo lib 3.1.10
is compatible with both 4.37main26341
and 4.38main27765
Snap Pack versions. To upgrade the JCo library on a specific JCC node, follow these steps.
Make sure there are no running pipelines on the node. In other words, put the node into maintenance mode to prevent new jobs from being created.
Shut down the JCC.
Required. Install the SAP JCo native library only on JCC nodes and not on FeedMaster nodes. However, installing it on FeedMaster nodes will not cause an issue.
Copy the updated native library:
For Linux, copy the updated native library
libsapjco3.so
file to the/opt/snaplogic/ldlib
folder on every node in the Snaplex.For Windows, copy the updated native library
sapjco3.dll
file to theC:\opt\Snaplogic\ldlib
folder on every node in the Snaplex.
Note: For Snaplexes with multiple nodes, make sure to install the library on every node.
Restart the JCC.
After the nodes resume, validate or execute the pipelines.
This upgrade can be done in a rolling manner so other nodes can be running, and the pipelines can resume. Refer to the FAQ for more information.
