\nEasier than unplug\/plug, you can move pluggable databases with remote cloning. It’s the same idea but you don’t have to manage the files yourself: the are shipped through database link. However, this uses the ‘remote file protocol’ and it fails with version mismatch:<\/p>\n

ORA-17628: Oracle error 17630 returned by remote Oracle server\nORA-17630: Mismatch in the remote file protocol version client  server<\/code><\/pre>\n
<\/p>\n
Remote cloning<\/h3>\n
I’ll describe the full operation of remote cloning in a future post. This is the error I got when I tried to remote clone from 12.1 to 12.2:<\/p>\n

The error is received from the remote side. There is not a lot in local alert.log<\/p>\n

Patch<\/h3>\n
Fortunately, version mismatch of remote file protocol has already been a problem in previous versions with other features that have to transport files, and a patch exists to bypass this version checking:<\/p>\n
Patch 18633374: COPYING ACROSS REMOTE SERVERS: ASMCMD-8016, ORA-17628, ORA-17630, ORA-06512<\/p>\n
And you can download it at https:\/\/updates.oracle.com\/download\/18633374.html<\/a><\/p>\n
My 12.1.0.2 DBaaS has the July 2016 PSU applied, as well as a merge of patches specific for the cloud:<\/p>\n
[oracle@HP121 ~]$ $ORACLE_HOME\/OPatch\/opatch lspatches\n19469538;\n24310028;\n22366322;\n20475845;\n18043064;\n21132297;\n23177536;Database PSU 12.1.0.2.160719, Oracle JavaVM Component (JUL2016)\n23054246;Database Patch Set Update : 12.1.0.2.160719 (23054246)<\/code><\/pre>\n
Today, there is no patch to download for this configuration. There is one for April 2016 PSU but there is still a conflict with patch 24310028<\/p>\n
To be able to continue, I’ve removed following patches from the 12.1 source:<\/p>\n
[oracle@HP121 ~]$ $ORACLE_HOME\/OPatch\/opatch rollback -id 23177536\n[oracle@HP121 ~]$ $ORACLE_HOME\/OPatch\/opatch rollback -id 24310028<\/code><\/pre>\n
But then, the parameter “encrypt_new_tablespaces” that has been introduced by 24310028 is unknown:<\/p>\n
\nSQL> startup\nORA-01078: failure in processing system parameters\nLRM-00101: unknown parameter name 'encrypt_new_tablespaces'<\/code><\/pre>\n
You have to remove this one from the SPFILE. Basically it forces TDE when in the cloud, even when not specified in the DDL.<\/p>\n
So what?<\/h3>\n
I hope this patch will be included in future DBaaS versions. Currently, the Oracle Public Cloud has no simple button to upgrade a service from 12.1 to 12.2 and the easiest way to do it should be remote cloning of PDB. But with those version mismatch and patch to apply, unplug\/plug<\/a> is probably easier.<\/p>\n","protected":false},"excerpt":{"rendered":"
