Does Shareplex support Automatic Storage Management (ASM)?
ASM is a new feature in Oracle Database 10g that provides the database administrator with a simple storage management.
Whether Shareplex supports ASM depends on its version.
Shareplex version 5.3
For this version,Shareplex does not support ASM managed online redo and archive log files stored in a filesystem managed by Oracle.
Shareplex cannot read ASM-managed files. Redo log and archive log files must be stored in a location that is not ASM-managed. Multiplexed redo and archive logs to an operating system or clustered file system (CFS) location will resolve this limitation for Shareplex. You must specify at least one member of the redo log on a regular file system NOT ASM managed so that shareplex can read this redo log member. In addition, enable the parameter SP_OCT_LOG_MEMBER with argument specifying non-ASM redo log member locations. Refer to the Shareplex Reference Manual for more information about this parameter.`
There is a known issue with this Paramter SP_OCT_LOG_MEMBER in Version 5.2 and 188.8.131.52.Capture will stop working when this parameter is set. This is fixed in 5.3.3.
Shareplex Version 6.0.1
ASM is now supported with this version. However, if the redo_log or archive_log that SharePlex is currently reading is involved in “rebalancing” due to the removal of a disc group, the Capture process will pause until the rebalance procedure for that file is complete.
NOTE: Working with ASM requires Shareplex 5.3 or above.
