Abstract:
Techniques herein make and use a pluggable database archive file (AF). In an embodiment, a source database server of a source container database (SCD) inserts contents into an AF from a source pluggable database (SPD). The contents include data files from the SPD, a listing of the data files, rollback scripts, and a list of patches applied to the SPD. A target database server (TDS) of a target container database (TCD) creates a target pluggable database (TPD) based on the AF. If a patch on the list of patches does not exist in the TCD, the TDS executes the rollback scripts to adjust the TPD. In an embodiment, the TDS receives a request to access a block of a particular data file. The TDS detects, based on the listing of the data files, a position of the block within the AF. The TDS retrieves the block based on the position.
