Order and Service Management (Communications Industry) (MOSC)

Orders are not creating in Sequence when we use Oracle RAC and getting skipped to 1000000 in OSM 7.2

This is expected behaviour in OSM 7.2, OSM will not use oracle sequence id for creating the order id's. For more information, please refer the OSM 7.2 release notes.

See OSM 7.2 release notes.

Order ID Generation

OSM 7.2 uses a new order ID generation mechanism. Each database server instance allocates order IDs in blocks. The instance then provides an order ID to each newly created order from the block, When all order IDs from the block are used, a new block is allocated. The overhead normally incurred by each instance to allocate sequence numbers such as the order ID one at a time and synchronize with other instances is avoided.

Howdy, Stranger!
