JR45498: ORACLE CONNECTOR JOB WITH LARGE SCHEMA/ARRAYSIZE FAILS WITH APT_BADALLOC WHEN USING BIG BUFFER API
A fix is available
Closed as program error.
An Oracle Connector job with a large schema and array size (specific case was 200+ NVarChar columns with no length set, getting default of 4000 bytes) fail with APT_BadAlloc when using Big Buffer API (new to 9.1). Job completes when using a smaller schema and/or array size or disabling Big Buffer API.
Work Around: Disable the big buffer APIs in V9.1
Big Buffer API uses a single buffer for an entire array of records, so if the array size and the record size are large enough, the connector will attempt to allocate a buffer larger than 2 GB. This size overflows the data type used to specify the length of the buffer, so this allocation cannot be allowed to happen.
If the Big Buffer initialization code determines that a buffer greater than 2 GB is about to be allocated, the connector will revert to the pre-9.1 method of transferring data with the connector framework.
Disable Big Buffer. Reduce the schema size (possibly by specifying lengths for strings). Reduce the array size.
