CLOSE return and reason codes
When your program receives control after it has issued a CLOSE macro, a return code in register 15 indicates whether all VSAM data sets were closed successfully, as Table 1 shows.
| Return code | Meaning |
|---|---|
| 0(X'0') | All data sets were closed successfully. |
| 4(X'4') | At least one data set (VSAM or non-VSAM) was not closed successfully. |
If register 15 contains 4, use SHOWCB to display the ERROR field in each access method control block to determine if a VSAM data set was not closed successfully and the reason it was not. See z/OS DFSMS Macro Instructions for Data Sets. Table 2 lists the reason codes that the ERROR field might contain after close processing.
| Reason code | Meaning |
|---|---|
| 0(X'0') | No error (set when register 15 contains 0). |
| 4(X'4') | The data set indicated by the access method control block is already closed. |
| 129(X'81') | CLOSE TYPE=T was issued for a VSAM data set that is not open for VSAM processing. |
| 132(X'84') | An uncorrectable I/O error occurred while VSAM was reading the job file control block (JFCB). |
| 136(X'88') | Not enough virtual storage was available in your program's address space for a work area for close processing. |
| 144(X'90') | An uncorrectable I/O error occurred while VSAM was reading or writing a catalog record. |
| 145(X'91') | An uncorrectable error occurred in the VSAM volume data set (VVDS). |
| 148(X'94') | An unidentified error occurred while
VSAM was searching the catalog. For a UNIX file, an unidentified error occurred. |
| 167(X'A7') | For MACRF=RLS, abend occurred during open or close processing. |
| 170(X'AA') | For MACRF=RLS, the required CF Cache is unavailable from this system. |
| 172(X'AC') | Close was successful, but DFSMStvs was unable to write a close record to the log of logs, the forward recovery log, or both. |
| 184(X'B8') | An uncorrectable I/O error occurred while VSAM was completing outstanding I/O requests. For a UNIX file, an error occurred while VSAM was flushing output data or disconnecting from the file. |
| 185(X'B9') | LSR/GSR - Error in WRTBFR: I/O for data set not quiesced before WRTBFR TYPE=DS during close processing. |
| 188(X'BC') | The data set indicated by the ACB
is not the type that may be specified by an ACB. For MACRF=RLS, an invalid ACB address is specified for close processing. |
| 236(X'EC') | System logic error because the function no longer is supported. |
| 246(X'F6') | A call to compression management services (CMS) failed. |
In addition to these reason codes, VSAM writes a message to the operator's console and the programmer's listing further explaining the error.
