ORACLE 12C pdb受限解決思路

PDB in restricted mode ,getting following error while trying to connect  :

ORA-01035: ORACLE only available to users with RESTRICTED SESSION privilege

SQL> select CON_ID,NAME,OPEN_MODE,RESTRICTED,OPEN_TIME from v$pdbs;

CON_ID NAME OPEN_MODE RESTRICTED OPEN_TIME                 <<<<<<<<<<< RESTRICTED

3      PDB1 READ WRITE YES 31.01.19 10:22:46,761000000 GMT

Pending Errors in pdb_plug_in_violations

SQL>  select name, cause, type, message, status from pdb_plug_in_violations where type = 'ERROR' and status !='RESOLVED' order

PDB1 Sync Failure ERROR "Sync PDB failed with ORA-65177 during 'alter user "xxx" ...' " PENDING     <<<<<<<<<

To solve the issue ,delete the offending statement ( alter user "xxx" ) from PDB_SYNC$ for both CDB and PDB

On CDB root ,make a backup of  PDB_SYNC$  table and delete de offending rows
