All credits go to Ricardo Maeda as I knew that we’ll release a Bundle Patch for Oracle sometime this week – but I couldn’t find it linked from the usual MOS notes. And please don’t ask my why that is.

GIMR DB in Oracle Database 12.2

I did blog in the past already about the Grid Infrastructure Management Repository Database (GIMR DB):

Grid Infrastructure Management Repository (GIMR)database now mandatory in Oracle GI

SID and DBNAME are kept the same in Oracle Database 12.2. But there are a few changes and additions in Oracle Database

Is your APEX version certified with your Database release?

Last week I’ve had an interesting discussion with a customer about the certification of APEX and Oracle Database

I did a bit of research and emailing – and thanks to the APEX team – this is the source of truth for APEX certifications.

Minimum Database version for APEX

See MOS Note:1344948.1: Application Express (APEX) Database and Web Server Certification Reference:

  • For APEX 4.0, the minimum database version is
  • For APEX 5.0, the minimum database version is
  • For APEX 5.1, the minimum database version is

Minimum APEX version per Database

What happens to PASSWORD_VERSIONS during an upgrade to Oracle 12.2?

I did blog a day ago about ORA-1017 connection issues in Oracle Database 12.2 once you would like to use the deprecated init.ora/spfile parameter SEC_CASE_SENSITIVE_LOGON=FALSE:

Having some fun with SEC_CASE_SENSITIVE_LOGON and ORA-1017

But how can this change actually happen?

Let’s check how the PASSWORD_VERSIONS is set in a fresh Oracle Database database with the January 2017 Proactive Bundle Patch applied to it:
