Place Files under the Management of CA-L-Serv

Consider the following factors before placing a file under CA-L-Serv management:

Before it can be opened, a VSAM file must be connected to a buffer pool. By default, VSAM assigns each file to a private (NSR) buffer pool. Optionally, you can direct the file server to create shared (LSR) buffer pools and assign your files to these buffer pools.
Deciding whether to use NSR (non-shared) or LSR (locally shared) buffer pools for a given VSAM data set is the function of a number of criteria including, the mix of I/O operations the client application performs. The application documentation generally recommends which of its files are assigned NSR and LSR pools and provides sample definitions.
You can assign a change log to each file. A change log collects information about updates to a file. See CA-L-Serv Configuration for more information about change logs.
You can assign each file to a file group. The files in a file group contain data that a particular client uses. All of the files in a file group must have the same file group characteristics. The client application documentation specifies which of its files must be part of a file group.
