BCAM memory values:

The values for the maximum size of the resident and paging memory for data transfers are calculated by BCAM at startup from the size of the system memory (BS2000 MEMSIZE system value). The relevant RESMEM and PAGMEM parameters should not be generally be specified in the BCAM /DCSTART, /DCOPT and /BCMOD commands, but should retain their values set by BCAM.

Memory monitoring can be activated with the BCAM /BCMON command (RECORD=(RES-MEMORY,PAG-MEMORY)) and this allows detection of whether the current values reach the limits.

Any adjustments to the memory values should only be made in agreement with the responsible first level support.

Parameter service:

The following class 2 system parameters have been supplemented:

- FILECRYP

Defines which symmetric encryption method is used for converting into an encrypted file with the ENCRYPT-FILE command.

Possible settings: AES (default) or DES.

The parameter can be changed during operation. The change has no effect on files that are already encrypted.

- FREFCRYP

The optional parameter can be used to limit the number of crypto passwords by only allowing new crypto passwords to be assigned for files of a specific ID.

Only the crypto passwords of reference files from this specific ID can be selected for files on other IDs.

The files from this ID are then assigned the same password as the reference file.

- NTPSHIGH

The parameter can be assigned the value "N" (default) or "Y". In the setting "Y", the time server NTP (NETWORK-TIMEPROTOCOL) is specified as the highest priority time server in BS2000.

With the default setting "N", the time quality (stratum value) is the deciding factor. NTP is assigned the highest priority if the stratum value is from 1 to 4.

Note: The parameter may only be used on S servers.

- JTSHMEM

Defines how much memory space (in MB) JITSYS is to use for stor- ing share compilations on SX servers.

Memory values between 0 and 255 MB can be specified. The default is 64 MB.

The memory size specified with JTSHMEM is allocated immediately when JITSYS is initialized.

Specifying JTSHMEM = 0 prevents share compilations from being created.
