Appendix A: CMX replication configuration settings

RUNCMXREP_STARTUP_SLEEPTIME_MS

The time to wait for the cmxrepsvr process to initialize before loading the subscriptions.

REP_MIN_REQUIRED_COMPRESSION_LEN

The minimum data length required for compression.

DEF_KEYHASH_THRESH

A positive value indicates the bulk transfer of data to the destination where table hashing is deferred until all records have been received.

DEF_CLIENT_TIMEOUT_SECONDS

The number of seconds before a remote procedure call (RPC) call times out.

DEF_NUM_LZW_BUFFERS

The number of buffers to allocate for the Lempel–Ziv–Welch (LZW) compression algorithm. Each buffer is 2 MB.

DEF_SUSPEND_TIMEOUT_SECONDS

The number of seconds the route has been suspended before an integrity update request is issued.

DEF_BULK_BLOCK

Determines whether to block on bulk transfers. Block if set to 1; don’t block if set to 0.

DEF_COMPRESSION

Determines whether to compress on transmission. The value can be 0, 1, or 2 for REP_COMPRESSION_NONE, REP_COMPRESSION_RLE, or REP_COMPRESSION_LZW, respectively.

DEF_FULFIL_TX_INTERVAL_SECONDS

The number of seconds between each fulfill transmission.

DEF_FULFIL_KEEPALIVE_INTERVAL_SECONDS

The number of seconds to wait before sending a "keep alive" message to the destination when the cmxrepsvr process has no data to transmit.

DEF_FULFIL_BUFFER_SIZE

The maximum buffer size for each fulfill transmission, in bytes.

MIN_FULFIL_BUFFER_SIZE

The minimum buffer size for each fulfill transmission, in bytes.

DEF_INTEG_HOLD_OFF_TIME_MILLISECONDS

The delay for issuing the integrity update requests, in milliseconds.

DEF_MAX_NUM_INTEG_FAILURE

The maximum number of consecutive integrity update failures. When this value is reached, the cmxrepsvr process waits for the integrity update hold-off time to expire before issuing another integrity update request.

DEF_XFRQ_STALE_FULFILTIME_SECONDS

The maximum number of seconds necessary to declare the transfer queue staled when no update is sent to the destination.

DEF_XFRQ_STALE_UPDATELENGTH

The maximum number of bytes allowed to be queued on the transfer queue. When this value is exceeded, the queue is declared stale.

DEF_XFRQ_MON_THROTTLE_MILLISECONDS

The number of milliseconds the transfer queue monitor will wait before it continues to pull the messages off the queue.

DEF_XFRQ_DUMP_STATS_THRESH_SECONDS

The interval where the statistics for the transfer queue service thread are printed out.

MAX_XFRQ_MESSAGE_SIZE

The maximum size of the transfer message, in bytes. If this is changed, MAX_UPDATE_SIZE will need to be recalculated.

DEF_MAX_DST_MESSAGE_SIZE

The maximum size of the message received at the destination, in bytes.

MAX_XFRQ_FORMAT_SIZE

The maximum size of the pre-processed data, in bytes.

If this is changed, MAX_UPDATE_SIZE will need to be recalculated.

MIN_SEND_TIME_MILLISECONDS

The minimum time interval for sending data to the destination.

DEF_PROCESSQ_MIN_POOL_SIZE

The minimum default queue size for the destination queue, in bytes.

Note: Always set this value to match the value of DEF_PROCESSQ_MAX_POOL_SIZE.

DEF_PROCESSQ_MAX_POOL_SIZE

The maximum default queue size of the destination queue, in bytes.

DEF_TIMERQ_THREAD_SLEEPTIME_MILLISECONDS

The number of milliseconds between each queue check.

MIN_TIME_INCREMENT_MILLISECONDS

General wait time used by the cmxrepsvr process.

MAX_UPDATE_SIZE

MAX_XFRQ_MESSAGE_SIZE + MAX_XFRQ_FORMAT_SIZE + 5024

CMXREP_REVERSE_COMMAND_DELAY_MS

A delay to fix RealTime sync issues (default: 10000 ms).
