Disk

Use this page to monitor the information about the three areas of space used by Enterprise Replication.

When a queue in memory fills, transactions are spooled to disk and saved in the following spaces:

• Row Data: The sbspaces that store the data to be replicated. They are defined in the CDR_QDATA_SBSPACE parameter.
• Transaction Record: The dbspaces that store the transaction record. They are defined in the CDR_HDR_DBSPACE parameter, if it is defined; otherwise, by the ROOTNAME parameter.
• Grouper Paging: The sbspaces used for large transaction handling. They are defined first by the SBSPACETEMP parameter, if it is defined; by the SBSPACENAME parameter, if it is defined; otherwise by the CDR_QDATA_SBSPACE parameter.

Important: When these spaces fill, ER stops responding until you either resolve the problem that is causing it to spool, or allocate additional disk space.

For each of these spaces, the Disk Usage page specifies the following information:

• Name: The name of the disk space
• Status: The state of the space, which can be:
  • Disabled
  • Recovering
  • Operational
• Size: The size of the space.
• Free: The amount of free area in the space.
• Used: The amount of occupied area in the space.
• # of Chunks: The number of chunks in the space.
• Logging Type: For sbspaces, whether the space was created with or without logging, indicated by ON or OFF.
