Shareplex for Oracle Alter table drop column is not supported by shareplex.
解决办法
Shareplex does not currently support alter table drop column. If you wish to issue this command you should remove the table from replication before issuing this command.
1. Copy the currently active config to a new file name and removed the line for the table you want to remove. 2. Restrict user access to table 3. Activate the new config with the table removed. 4. Issue a flush in sp_ctrl 5. Issue your alter table drop column on the source 6. Reactivate the original config 7. When the target post is stopped due to flush you can issue the alter table drop column on the target and then start post. 8. You are finished.
