• Article Type: General
• Product: Aleph
• Product Version: 21

Problem Symptoms:
The following error occurs in AIK step 3.1 (ikit_3_1) ("Extract Oracle software") for an Aleph 21 site upgrading to Aleph 22:

"Error: Existing Oracle Home has version , PLease upgrade to 11.2.0.4.0 before you can continue"

Cause:
Cause 1:
This is a version 21 instance and /exlibris/app/oracle/product/11r2 contains the v21 Oracle 11.2.0.3.0, which needs to be upgraded.

Cause 2:
AIK Step 3.1 is implemented by the script /exlibris/ftp_from_exlibris/AIK22/ikit_3_1.
The script ikit_3_1 calls the shell function CHECK_ORA_VER which is defined in the file /exlibris/ftp_from_exlibris/AIK22/param_bash.func.
The function CHECK_ORA_VER calls the program $ORACLE_HOME/bin/sqlplus with the option -v, in order to display the version of that program.
The version of sqlplus is equivalent to the version of the Oracle software installed in the directory $ORACLE_HOME.
The function CHECK_ORA_VER returns the Oracle version in the variable $ORAVER.

In the case of Aleph 22 the AIK variable $ORACLE_HOME has the value /exlibris/app/oracle/product/11r2.
If the directory /exlibris/app/oracle/product/11r2 exists but the program /exlibris/app/oracle/product/11r2/bin/sqlplus does not exist (e.g. because the directory 11r2 is empty),
then the function CHECK_ORA_VER returns an empty string (ORAVER = "").

After that the script ikit_3_1 executes the following function:

ERROR "Existing Oracle Home has version $ORAVER, PLease upgrade to $ORACLE_VERSION before you can continue"

This function writes the following error message to the AIK log file /exlibris/ftp_from_exlibris/AIK22/log/aleph_installation_kit.log:

"Error: Existing Oracle Home has version , PLease upgrade to 11.2.0.4.0 before you can continue"

Root cause:
===========
This behavior of the AIK script ikit_3_1 is a bug (in the case of this Cause #2).

Resolution:
For Cause #1:
Upgrade the v21 Oracle 11.2.0.3.0 to 11.2.0.4.0. See Article 000036538 ("Aleph 22: AIK Step 3.3 fails with error message "ERR: Oracle software versions are different on the target and source servers" ) in this regard.

For Cause #2:
This is a version 21 instance and /exlibris/app/oracle/product/11r2 contains the v21 Oracle 11.2.0.3.0. In this case, the 11.2.0.3.0 needs to be upgraded to 11.2.0.4.0. Consult Article 000036538 (see link below).

General workaround:
-------------------
If no Oracle software exists in the directory /exlibris/app/oracle/product/11r2, then remove that directory.
After that, execute AIK Step 3.1.

Development is working on a change to prevent this message in this case (Cause #2).

Note: in the case of a TWO_TASK set-up, see Additional Information below.
