Summary0012478: Installation with Oracle fails

When installing Mantis with Oracle, the automated installation fails, with Fatal error: 401.
So I asked Mantis to generate SQL script which I runned manually. This failed again. I had to do 3 modifications on the script for installation runs to the end:

  1. Replace “;;” (on lines “CREATE OR REPLACE TRIGGER … END;;” with “;\n/\nshow errors;” (not sure the show errors is needed). So the lines now look like:
    show errors;

  2. Replace the index name “idx_project_hierarchy_parent_id” with “idx_project_hierarchy_parnt_id”. I removed the last “e” because the identifier was initially too long for Oracle (limit: 30 characters).

  3. Change the table name for the last “INSERT INTO mantis_config_table”. The table name is hard-coded. For Oracle, we need to change default table names because mantis prefix and table sufix creates identifiers too long.

Hope this will help doing a clean Oracle installation process…

Sorry, I will not have time to make a patch for this issue, as my company finally abandoned the idea of using Mantis with Oracle.

Thanks. Out of curiosity, have you abandoned the idea of using Mantis or just switched to another DB?

We are actively using Mantis, but with MySQL…
I made some tests about Oracle, and based on those, we considered that there were too many risks switching to this it.

Fix 0013227: Oracle database support (oci8)

Mantis 1.2.6 currently does not work with Oracle DB:
1. Installation:
1.1. Oracle DB autocreates PK, so index creation for same field forbidden
1.2. Oracle DB uses datetime literal format timestamp'YYYY-MM-DD HH-MI:SS'
1.3. Oracle DB don't allows altering field property NOT NULL into NOT NULL
1.4. Oracle DB max object length is 30 chars, so some index names must be reduced
1.5. Oracle DB means empty string as NULLs, so NOT NULL restriction must be disabled for some field
1.6. Oracle DB can resolve database server name through TNS, so database name cannot be required
2. General:
2.2. Direct DB query execution result accessing instead of db_fetch_array() 1.3. usage didn't works with Oracle DB
2.4. Oracle DB binds variable by name, so bind names in statement must be sorted to address them.
2.5. Oracle DB handles NULL/DEFAULT values with specific way.
2.6. Oracle DB returns NULL value as true PHP null
2.7. Oracle DB handles sequence access with specific syntax
2.8. Nothing returned by db_prepare_string() in case of oci8
2.9. Oracle DB max object length is 30 chars, so table names must be reduced
2.10. Oracle DB uses LOB literal format similar to mssql
2.11. GetRowAssoc returns empty field values with oci8, it's need to enable returning both associative and indexed arrays.

The original patch was provided by DKuranov. He reckons that this also resolves
