short.text=CMGR RPC call returns NULL

long.text=The ndmapi_sendcmd RPC call made by the API to the CMGR returns a NULL pointer.There is probably an RPC error.ndm.action=None user.action=First, check if the ndmcmgr is still running; it could have been killed accidently.If so, then abort the current CLI and restart the CLI. If the same problem occurs again, try to increase the value of wait time (if set) in the API configuration file (ndmapi.cfg).

Precompressing/Decompressing Files Using the Standalone Batch Compression Utility

The Standalone Batch Compression Utility (cdsacomp) enables you to precompress files and then transfer the precompressed files to remote Sterling Connect:Direct nodes using Sterling Connect:Direct Processes. You have the following options for decompressing the files. A file can either be:

vDecompressed as it is received by the remote node (available on all Sterling Connect:Direct platforms)

vStored on the remote node and later decompressed offline using cdsacomp (available only on Sterling Connect:Direct and Sterling Connect:Direct for z/OS).

Because cdsacomp can be used offline, it allows you to allocate some of the overhead associated with compression to non-peak times. For example, if you need to send the same file to several remote nodes, use this utility so that the file is precompressed only one time. You can also use cdsacomp to determine how much compression can be achieved for a file without having to transmit the file.

The cdsacomp utility is located in the Sterling Connect:Direct /bin directory.

Special Considerations for Using the Standalone Batch Compression Utility

Consider the following when you are using cdsacomp to precompress files:

vIf you precompress a file with the cdsacomp utility, then you cannot specify any compression options in your Sterling Connect:Direct Process when you copy that file.

vYou cannot specify data transformations (xlate, codepage, strip blanks, and so on) when sending a precompressed file with :precompress=yes: sysopts (for on-the-fly decompression). The following transformation options are available:

–-x

–-p

–-s

–-a

vIf you precompress a file with the cdsacomp utility on a Sterling Connect:Direct node, then you cannot specify a checkpoint interval in your Sterling Connect:Direct Process if you decompress the file as it is received by the remote node.

vWhen you are copying a precompressed file to z/OS without :precomp=yes: (for deferred decompression):

–The Copy operation must specify DCB information for the destination file. The physical block size of the destination file on Sterling Connect:Direct for z/OS must match the logical block size of the precompressed source file on Sterling Connect:Direct for UNIX.

–The logical block size of the source file defaults to 27920 unless overridden by the -b parameter.
